Human Baseline
The handle went down.
Leo moved before the door could open.
He shoved the warm registration strip into his left jacket pocket, set the delivery bag against the wall, and stepped to the hinge side of the doorway. The folding utility knife shook once as he opened it. He tightened his grip until the blade stopped moving.
The black GBA beacon stood three meters to his right. Its blue line pulsed across the empty corridor. Beyond it lay the severed white tether and the blank wall where the stairwell had been.
No agents returned through it.
No one called his name.
From inside apartment 4812, Leo's voice said, “Not there. The other side.”
He did not obey.
The door opened inward.
First came a narrow slice of the small entry area. It opened directly into the living room, with the black stone of the kitchen to the left and the short passage toward the bathroom and bedroom to the right. Nothing crossed the threshold. No hand held the handle from inside.
The door stopped halfway.
Leo waited beside it with the knife raised.
The apartment smelled of old dust, wet plaster, and the coffee still cooling inside his delivery bag. The layout was the same one he had searched while the delivery anomaly still held him. The furniture remained decayed. The stains remained dry. The D-rank description did not return.
Whatever had spoken in his voice was not standing where he could see it.
“Come in,” the voice said from the bedroom.
Leo looked at the open apartment, then at the corridor.
The route was gone. The GBA had left him beside a wall that had answered a question. Somewhere inside the tower, “Tenant from the Wrong Floor” was still active. Apartment 4812 was either shelter or a mouth holding itself open.
The wallpaper behind the beacon darkened.
At first the stain looked like a person seen through several layers of paper. Then a shoulder peeled away from the wall. A flat head turned toward Leo. One long black arm slid outward without gaining thickness.
The Tenant had appeared between him and the place where the stairs should have been.
Leo kept the knife down.
He already knew what violence would do. One pull of D-17's trigger would have given the thing a body. His blade would be a smaller mistake, not a different one.
The silhouette moved along the wall toward him. Its fingers opened. A vertical seam appeared in its face, and something clicked behind it like a lock being tested.
Proof first.
Leo had no key.
D-17 had brought the ring of keys marked for this floor. The key stamped 4811 had last been in the scout's hand; now neither it nor any other key lay within Leo's reach. Leo had the nameplate on the door, but the rule he had seen was specific: a key from an apartment on the current floor.
The black fingers lengthened across the wallpaper.
From the bedroom, his voice said, “Left pocket.”
Leo's left pocket held the folded registration strip. He had put it there seconds ago. Nothing else.
Metal pressed against his knuckles when he reached inside.
He pulled out a brass key.
4812 was stamped into its round head.
The key was warm, as if it had just come from someone else's hand.
Leo's breath caught. The Tenant reached the edge of the doorframe.
Questions could wait.
He raised the key without pointing the knife.
“Forty-eighth floor,” he said. “Apartment four-eight-one-two. I have the key.”
The silhouette stopped.
Its featureless face stretched toward the brass. A lock turned somewhere inside the wall.
Once.
Then the long fingers folded back into the wallpaper. The shoulder flattened. The head sank last, leaving a dark human outline beside the beacon.
The blue light passed over it and did not change.
Leo remained still until the lock-sound faded.
The key had bought him until the next day. The silhouette would not ask again before the daily reset.
The voice inside the apartment said, “Good.”
It sounded relieved.
That frightened him more than if it had laughed.
Leo picked up the delivery bag and backed across the threshold, keeping the corridor in view until he could swing the entrance door between himself and the outline in the wall.
The new key entered the lock without resistance.
He turned it once. A bolt slid into place.
He tried a second rotation. The mechanism stopped like an ordinary lock.
Ordinary was now something he tested instead of something he trusted.
Leo backed away from the door.
The small entry area opened directly into the living room. The kitchen occupied the left side, separated from the rest of the space by a broad stone island. Panoramic windows filled the far wall. To the right, a short passage led past the bathroom to the bedroom. There were no other rooms and nowhere else for a person to hide except the cupboards, wardrobe, and spaces beneath the ruined furniture.
He checked them anyway.
The bathroom came first. Cracked gray tile. An empty bathtub beneath a broken showerhead. A cabinet above the sink with its mirrored doors hanging open. Leo kept his eyes below the mirror and searched behind it, under the sink, and inside the narrow utility closet.
No one.
He crossed the passage to the bedroom.
The door stood open. A low bed sagged beneath a layer of dust. One panoramic window looked down over central Meridian. The wardrobe contained three damp wooden hangers and nothing else. Leo crouched far enough to see beneath the bed without putting his face near the dark gap.
Nothing waited there.
He straightened.
From the kitchen behind him, his voice said, “Bedroom clear.”
Leo turned.
The passage was empty.
To reach the kitchen, anything leaving the bedroom would have needed to pass within arm's length of him. Nothing had. The voice had simply changed rooms.
“You're not a recording,” Leo said.
No answer came.
He shut the bedroom door. From the paper receipt on the delivery bag, he tore a thin blank strip and wedged it between the door and frame at knee height. If the door opened, the strip would fall.
Then he searched the living room and kitchen.
The overturned couch had no intact upholstery left to conceal anything. Dust filled the cabinets. Most of the plates had broken inside them. The refrigerator door stood open, revealing black shelves and a smell that made Leo close it at once. In a lower drawer he found two sealed garbage bags, a box of water-damaged matches, and a roll of foil.
No person. No fresh footprints. No second source for his voice.
His own tracks from the first search still crossed the dust. They led from the kitchen to the bedroom passage, doubled back, and ended at the entrance where he had escaped the apartment anomaly.
A new footprint lay beside them.
Same length. Same worn edge on the right heel. Same diagonal cut in the sole of his courier shoe.
It pointed from the bedroom toward the kitchen.
There was only one.
Leo looked down at his shoes, then at the closed bedroom door.
The paper strip remained in place.
He used the edge of his shoe to draw a circle around the print. Next to it, he scratched a line into the dust and added the time shown on his phone. The screen had no network, but the clock still advanced.
“If another one appears, I want to know,” he said.
From behind the bedroom door, his voice replied, “You will.”
Leo stared at the intact paper seal.
Then he dragged one of the dining chairs into the entry area and braced its back beneath the door handle.
It would not stop an anomaly. It might stop a door from opening quietly.
That was enough to make it useful.
The tap worked.
Leo stood to one side of the kitchen sink and turned the handle with the tip of the folded knife. The pipes coughed. Brown water spat into the basin, cleared slowly, and became a steady cold stream.
He let it run while he watched for impossible behavior.
The water fell downward. It remained inside the sink. Its reflection moved at the same time as the stream.
None of those observations would have deserved a thought that morning.
He filled a glass, smelled it, and held it up to the light from the windows. No text opened across his vision. That did not prove the water was safe. It only proved that, if something was wrong with it, his ability had not recognized an active anomaly.
Leo drank one mouthful.
He waited.
Nothing spoke from inside his stomach.
He drank the rest.
The cabinet above the sink clicked open before he reached for it.
Leo froze with his hand halfway up.
The door swung a few centimeters and stopped. Inside stood a clean tumbler that had not been there during his search.
He closed the cabinet without touching the glass.
The apartment had given him a key when the corridor demanded one. Now it had offered a cup after he found water.
Helpful was not the same as safe.
The GBA commander had never called him hostile. She had not needed to. An unknown S-rank effect was enough to leave him behind.
He understood her logic better now than he wanted to.
Leo carried the original delivery bag to the island and unpacked it. Black coffee. Beef broth in a sealed container. A slice of apple pie. All three had crossed with him from his world. The receipt still showed the destination, the price, and the order number, but the recipient field contained only:
ADDRESSEE NOT FOUND
The food no longer belonged to a specific person. The mark in his left forearm stayed silent when he lifted the bag. Right of Delivery did not tell him where to go, create a route, or invent someone willing to receive it.
One authorized door would be useful later.
It was not an escape plan.
The broth was still warm. Leo removed the lid and waited for a face to appear in the surface.
Only ceiling cracks looked back at him.
He drank half the container before his stomach reminded him to slow down. Then he ate the pie with his fingers. The sweetness felt obscene in the dead apartment, but his hands stopped trembling quite so badly.
He left the coffee untouched. His heart had done enough work for one night.
In the bathroom, Leo washed the dried blood from his mouth. The split inside his lower lip opened again when he touched it. His right forearm ached from wrist to elbow, and the black 81 beneath the skin looked darker under the bathroom light. On his left arm, the first of ten circles held the tiny door-shaped mark of the absorbed function. The other nine remained empty.
His face in the mirror looked exactly like his face.
He checked because he no longer trusted that to remain true without supervision.
Average height. Light-brown hair stuck to his forehead. Gray eyes ringed with exhaustion. A courier's jacket smeared with dust and someone else's dried plaster.
No scales. No second mouth. No black line dividing him into before and after.
The GBA had still printed S-RANK beside his name.
Leo lowered his gaze.
The warm registration strip lay folded beside the sink. On one side, the GBA ordered any attempt to take him beyond external containment suppressed at any cost. On the other, something had welcomed him home.
Two authorities had assigned him a place within minutes.
Neither had asked where he wanted to live.
He picked up the strip and returned it to his pocket beside the impossible key.
Forty-eighth floor. Panoramic windows. No mortgage. At least he finally had an apartment of his own.
The neighborhood was rough even by end-of-the-world standards.
Leo laughed once, then stopped.
For several seconds, the apartment was quiet.
Then three knocks came from the bedroom.
Not the entrance door. Leo could see the chair still wedged beneath that handle. The sound came from the far side of the bedroom door, where the strip of receipt remained pinched between wood and frame.
Three polite knocks.
The same number the delivery instructions had required.
Leo did not answer.
He took the utility knife from the bathroom counter and sat behind the island, using the stone as cover while keeping the sealed bedroom door in view. His body wanted him to keep moving. Search again. Open the bedroom. Prove it was empty for the third time.
That was how the first anomaly had controlled him: it had made the next reasonable action part of its sequence.
He stayed seated.
The knock did not repeat.
“You aren't the Recipient,” Leo said.
No reply.
The causal kernel of “Recipient Does Not Answer” had collapsed. He had watched the false delivery break apart. Its rules had vanished. The remnant now existed as a mark in his arm and a reduced function he could feel when he touched it.
The voice could be residue. A recording caught in the apartment. A final loop continuing after the machine that produced it had stopped.
But recordings did not put keys into pockets.
Recordings did not open the correct cabinet.
Leo opened the notes application on his phone.
The battery icon was lower than he wanted. He switched on power-saving mode, reduced the brightness, and typed a heading.
DO NOT DIE
He looked at it, deleted it, and tried again.
PLAN
That was less dramatic and more useful.
He numbered the first line.
1. Secure shelter.
Apartment 4812 had water, one entrance, a key accepted by the corridor anomaly, and a phenomenon using his voice. Calling it secure required a generous interpretation of the word.
NovelFire is the home of this novel. Visit there to read the original and support the author.
Still, the tower outside contained changing arrows, missing stairs, and walls that checked residency by touching people. The apartment was the only place that had helped him twice without demanding blood.
He added:
Use 4812 as base. Mark every door and object. Never assume empty means empty.
“Two,” his voice said from the bedroom.
Leo's thumb stopped above the screen.
He had not spoken the number.
He typed it anyway.
2. Water, food, medicine, sleep.
The bathroom cabinet contained antiseptic wipes in intact foil packets, a roll of gauze, and painkillers whose printed date had faded. The cupboards held no edible food. The meal from his world would last until morning if he saved the rest of the broth. Water ran, but he had no way to know whether it would continue.
He filled every clean container he could find: the stockpot, two bottles from a lower cabinet, a glass jar after washing it, and the bathtub to below the cracked overflow drain. He did not use the clean tumbler the apartment had produced.
When he turned toward the kitchen, the refrigerator was still closed, but the rotten smell had returned to the room.
He crossed to the appliance and pulled the handle open with the knife tip.
The black shelves remained empty.
The smell came from the bedroom passage.
It faded before he reached the first tile.
Leo returned to the island and typed:
Find sealed supplies elsewhere on floor. Do not eat anything newly offered by apartment.
“Three,” said the voice.
This time it came from the bathroom.
From behind the island, Leo could see the bathroom doorway. No one stood there.
The voice was not simply trapped in the bedroom. It moved without crossing the passage, just as it had moved during his search.
He typed the next line.
3. Map the tower.
The building's internal numbering could change. The stairs had been replaced by a wall. Arrows contradicted one another. A route that existed for the GBA had folded shut in seconds.
A conventional map would become wrong.
That did not make observation useless. It made dates, directions, and return checks more important. He needed the emergency plan for the forty-eighth floor, every apartment number he could verify, and marks that showed when a corridor changed after he passed through it.
Courier work had taught him that buildings lied in ordinary ways. Service entrances were omitted. Elevators skipped floors. New towers reused apartment numbers across different sections because an architect liked symmetry more than delivery drivers.
Meridian lied with greater ambition, but it still had doors, hinges, pipes, and residents who had once needed to reach the street.
He added:
Photograph intersections from both directions. Leave paired marks. Trust a route only after returning by it.
The phone could store photographs without a network. Its battery could not last forever. Finding power became part of the same problem.
The kitchen outlets were dead. The bathroom light had not come from the ceiling fixture; it was the weak gray glow of the city entering through frosted glass. He tried his charger in each socket once, then unplugged it. No power.
The broken television clicked on behind him.
Leo turned so quickly that pain flashed along his right arm.
The screen showed a white battery symbol on black.
Below it, a number climbed from zero.
One percent.
Two.
Three.
His phone, lying unplugged on the island, vibrated. The battery icon began filling.
Leo snatched it up.
No cable. No wireless-charging indicator. The case felt cold.
The television number reached four.
Leo pressed the power button on the television.
The screen went dark. His phone stopped charging.
Four percent more than before.
He stared at the dead screen.
The apartment had understood a need he had not said aloud. It had not merely anticipated the next word in his list. It had acted on the problem behind it.
Helpful, again.
Leo wrote:
Apartment can affect phone. Do not let it charge unattended.
He considered turning the television back on. Four percent could matter later.
He left it dark.
“Four,” the voice whispered from beneath the island.
Leo drew his legs back.
Nothing occupied the open space below the stone counter.
His next line was harder to write.
4. Learn anomalies before touching them.
The apartment anomaly had tried to replace him. The Tenant had stopped when shown a key. The GBA agents had carried weapons capable of hurting things that ordinary bullets could not, yet they had lowered those weapons when a rule offered a safer answer.
Not every anomaly was an enemy. Not every helpful one was a friend.
Leo could not afford to change rules merely because he disliked them. A bad edit might make a manifestation stable instead of destroying it. Violence could do the same. He had seen how close D-17's finger came to materializing the Tenant.
D-17.
The scout's last words returned without permission.
Wait, I'm not through—
Leo looked toward the entrance.
The blank wall beyond it had flashed with the red of D-17's collar. A voice inside the wall had asked who escaped. It might have been the scout. It might have been something that had learned him in the last second before the route closed.
Leo could not go looking until he knew where the stairs were.
He hated how sensible that sounded.
He typed:
D-17 unknown. Do not assume dead. Do not follow voices into walls.
The apartment did not read the next number aloud.
Leo entered it himself.
5. Energy.
The number under his right wrist remained 81. It had not increased since the absorption. He knew the zone contained energy; he had watched GBA exoskeletons draw blue light from the air. He did not know whether his own reserve replenished with time, proximity, sleep, or anything else.
Assuming it did would get him killed.
What he knew was narrower. Rule edits spent energy. Resolving and absorbing one destabilized anomaly had restored fifty units and occupied one of ten slots. The function left behind had been weaker than the original anomaly but usable.
Nine empty circles were not an invitation to fill them carelessly.
If every absorbed rule remained in him, then survival could become another way of replacing himself piece by piece.
He added:
Record every change. Keep energy for emergencies. Absorb only after understanding what remains.
His thumb hovered before the final item.
The wall surrounded all 812 square kilometers of Meridian. The GBA could not maintain a route to the center. Their machine had calculated that taking him might pull a seven-kilometer section of the city to the wall. If he approached external containment, they had orders to suppress him at any cost.
An hour ago, Leo had worried about cold noodles and an alarm.
Now a multinational agency had printed instructions for killing him if he tried to go home.
His chest tightened. For a moment the apartment seemed to tilt, though the water in the glass remained level. He placed both palms on the island and waited until each breath reached the bottom of his lungs.
The GBA was not coming back to rescue him.
Even if another route opened tomorrow, the answer would remain the same. Human body. S-rank causal signature. Evacuation prohibited.
He could spend days waiting beside the beacon for someone to repeat the refusal, or he could decide that the refusal was information.
Leo typed:
6. Get out.
Not through the wall tomorrow. Not by following an arrow into concrete. First secure the apartment. Then the forty-eighth floor. Then the tower. Then central Meridian.
The apartment in his world and apartment 4812 occupied the same address. He had crossed between them once. That made this room his only evidence that a route home existed at all.
The collapsed delivery anomaly had briefly exposed a GBA route. Perhaps other resolved anomalies could reveal passages through the city. Perhaps Right of Delivery could open one locked door when he finally had a real recipient and a real route. Neither possibility was a solution yet.
They were directions in which a solution might exist.
He expanded the last line.
Leave the tower. Reach the edge of Meridian. Find why 4812 exists in both worlds. Return home.
The cursor blinked after the final period.
From the bedroom, his voice said, “That will take a long time.”
Leo looked at the sealed door.
“Then I'd better live that long.”
This time the apartment did not answer ahead of him.
Leo's plan had an obvious weakness.
It depended on Leo.
The GBA team had crossed central Meridian wearing powered armor. They had carried anomalous weapons, sealed containers, a route machine, and enough training to discuss a collapsing corridor without raising their voices. Four of them had reached the forty-eighth floor. Their armor had been torn open. The route machine had arrived dragging a severed tether with an armored hand still attached.
Leo had a folding knife designed for tape and cardboard.
Knowing a rule would not help if he died before he could finish reading it.
He looked at the black number beneath his right wrist.
Eighty-one units of energy had done nothing while they remained stored. Nineteen had broken a lethal obligation. The difference was not possession. It was use.
That did not mean spending all of it was brave.
It meant refusing to consider the question was cowardice disguised as caution.
Leo moved the knife, the key, and the glass away from his hands. He sat on the floor with his back against the kitchen island, both arms visible in front of him. If something went wrong, he wanted to see which part of him changed first.
The description had appeared when the GBA registered his name. He tried to recall the sensation: not looking at words in the air, but directing attention toward a structure that had always been behind his vision.
He focused on the name under the skin.
Leo Brown.
Not the sound. Not the letters. The thing the GBA scanner had found when it used the name as a designation.
Pressure gathered behind his eyes.
Text opened.
S-RANK ANOMALY
Designation: Leo Brown
Causal kernel: Forming.
Active internal rules: 5
Current anomalous energy: 81
Absorbed functions: 1/10
The five internal rules remained the same. Perception. Editing. Absorption. The restriction that erased human understanding of his power. The rule preventing any medium from bypassing that restriction.
Below them waited the two commands he had refused to touch in front of the GBA.
EDIT
ADD
Leo chose ADD.
The word opened like a blank field.
His first thought arrived without discipline.
Make me impossible to kill.
The blank field remained empty.
Too vague. Death could mean a stopped heart, a destroyed brain, a lost identity, a body erased from history, or a person who remained alive after becoming something else. Meridian had already demonstrated that ordinary definitions were openings, not protection.
Leo tried again. He defined what he wanted instead of what he feared.
Proposed permanent internal rule:
“The integrity and continuity of Leo Brown's body, mind, identity, and existence cannot be reduced, interrupted, overwritten, or erased by any force, process, anomaly, rule, or causal event.”
Cost: 1,000,000 anomalous energy.
Available: 81 anomalous energy.
Insufficient energy.
Leo stared at the six zeros.
The good news was that absolute invulnerability existed.
The bad news was that it was approximately as affordable as everything else he wanted.
Still, the response changed something important. The system had not called the rule forbidden. It had named a price.
A price, not a prohibition.
He dismissed the proposal and touched the split in his lip.
Preventing all harm was impossibly broad. Repairing harm after it happened should be narrower.
He specified a living body because he did not want to discover, too late, that regeneration and resurrection were different words.
Proposed permanent internal rule:
“While Leo Brown remains alive, every loss of structure or function in his body—including disease, poison, organ loss, and limb loss—is immediately and completely restored to the healthy state defined by his active internal rules.”
Cost: 1,000 anomalous energy.
Available: 81 anomalous energy.
Insufficient energy.
Three fewer zeros did not make the rule useful tonight.
Leo dismissed it too.
The pressure behind his eyes eased. The cut in his mouth still hurt. Previewing a rule did not grant even a fraction of it, and closing the proposal returned nothing because nothing had been spent.
He checked the number under his skin.
81.
Next he considered skills.
Strength without knowing how to strike could break his own fingers. A knife was more dangerous to its owner when held badly. If ADD could alter the body, perhaps it could also place learned movement into the nervous system.
He began with a limited formulation.
Proposed permanent internal rule:
“Leo Brown possesses the motor patterns and practical judgment required for competent basic unarmed combat under real danger.”
Target-state cost: 10 anomalous energy.
Current acquired proficiency: none.
Ten.
He could afford it.
The possibility made his hands feel less like his own. Somewhere inside those words were stances he had never practiced, decisions he had never made, and the reflex to hurt another body before conscious thought caught up.
Leo refined the target rather than accepting it.
Proposed permanent internal rule:
“Leo Brown possesses the integrated motor patterns, timing, distance control, defensive reactions, and tactical judgment of an advanced unarmed combatant.”
Target-state cost: 25 anomalous energy.
Current acquired proficiency: none.
One more refinement.
Proposed permanent internal rule:
“Leo Brown possesses the maximum unarmed-combat technique, timing, adaptation, and tactical judgment attainable by a human without anomalous modification.”
Target-state cost: 50 anomalous energy.
Current acquired proficiency: none.
Target-state costs are not cumulative. The cost of existing acquired proficiency is deducted from a later upgrade.
Basic for ten. Advanced for twenty-five. The human peak for fifty.
Leo could purchase any one of them. If he bought the basic level now and later raised it to advanced, only the fifteen-unit difference would remain. The rule did not demand that he pay twice for the same learned movement.
For several seconds, he considered the basic version.
It was cheap enough to feel responsible.
That made it more dangerous.
Combat skill would help against a human attacker. It might help him keep the knife out of someone else's hand. It would not let him outrun a corridor folding shut, carry water up forty-eight floors, hold a door against a creature, or remain conscious after a night without sleep. It would not make an ordinary fist useful against a flat thing living in wallpaper.
The peak version demanded fifty because it had to create years of organized decisions inside his nervous system. Power and causal complexity were not the same thing.
And Leo did not want his first deliberate change to his mind to be a set of violent reactions he could not distinguish from instinct.
Not never.
Not now.
He dismissed the proposal.
The reserve remained 81.
What he needed first was not a weapon. It was more of what his body already did: run, climb, carry, notice, react, endure.
The simplest wording came immediately.
Leo Brown is twice as strong.
He did not submit it.
Muscle pulled against tendon. Tendon transferred force through joints. A stronger leg with ordinary balance could send him into a wall faster. Faster hands with ordinary perception would only make mistakes arrive sooner.
He needed the systems to change together.
The idea frightened him because it was sensible.
The face in the bathroom mirror had been his final piece of evidence. Human skin. Human eyes. Human pain. The GBA could call the whole arrangement an anomaly, but nothing in it had been chosen or built.
Now he was considering rewriting it on purpose.
If he added a new organ, a new sense, or tissue that no human possessed, he would spend every later day asking whether that was the moment the GBA became right.
Doubling what was already there felt different.
That might be self-deception. It was still a line he could define.
Before defining it, Leo decided to establish what the line contained.
He propped the phone against the coffee container and aimed its camera across the clear space beside the island. The clock, camera, and timer did not need a network. Neither did his body.
He started with controlled movements.
Ten push-ups, slow enough that momentum could not help. His arms began to shake on the seventh. On the tenth, the ache in his right forearm sharpened and he stopped rather than turning a baseline test into an injury.
He listened to his breathing while the phone timed its return to normal.
After each exhale, a softer breath followed from the bedroom passage.
Leo held his breath.
The second breathing stopped.
He waited until his lungs forced him to inhale.
The sound behind the bedroom door inhaled a fraction earlier.
Leo stood.
The paper strip remained wedged in the doorframe.
He walked to the entrance. The chair had not moved. The key remained in his pocket. The blue line of the GBA beacon passed beneath the door at regular intervals.
No one had entered.
When Leo returned to the kitchen, the phone recording contained only his own breathing.
He played it twice.
Nothing answered from the speaker.
The apartment remained silent while the recording played, as though it knew the difference between Leo and a copy of his sound.
He continued because stopping would not make the second breath less real.
The full stockpot stood on the floor beside the sink. Leo had filled it almost to the rim. He lifted it with both hands, placed it on the island, rested, and returned it to the same marked tile. The weight pulled at his shoulders and forced him to brace it against his body.
He made a note of the effort, not a claim about kilograms he could not verify.
For reaction speed, he balanced a spoon on the counter edge, released it with his left hand, and tried to catch it with his right before it struck a folded towel. The phone's slow-motion recording showed the same pattern across several attempts: his fingers began closing after the spoon had already fallen most of the distance.
For coordination, he walked heel to toe along a seam in the stone while looking toward the bedroom instead of at his feet. Fatigue pulled him off the line twice.
For sight, he placed the painkiller packet on the far end of the island and moved back until the smallest print blurred. For hearing, he stood in the living room and noted the faintest sounds he could separate: water shifting in the bathroom pipes, rain ticking against the fractured window, and the GBA beacon's internal printer making one dry mechanical movement each time its blue light crossed the casing.
He did not test maximum speed in a room full of stone corners.
The results were not impressive.
They were human.
Tired, untrained, frightened, and human.
Leo sat again and constructed the rule around that fact. The comparison had to be his healthy, unmodified body—not tonight's exhaustion and not the body created by the new rule. Otherwise double might feed on itself.
The apartment listened without speaking.
Leo submitted the wording.
Proposed permanent internal rule:
“The upper limits of Leo Brown's existing physical capabilities—strength, speed, reaction, coordination, endurance, and natural sensory acuity—are permanently set at 200% of their healthy, unmodified pre-edit baseline.”
New capabilities added: None.
Learned skills added: None.
Cost: 40 anomalous energy.
Available: 81 anomalous energy.
Energy after addition: 41.
Add rule?
Forty.
Ten less than peak combat mastery. A coordinated amplification of structures already present was cheaper than manufacturing the neural result of years of training.
The edit would leave him with forty-one—enough for two changes close to the narrow rule that had freed him from the delivery obligation, provided the next problems were equally specific. That was not a guarantee. It was a reserve.
Leo read the proposed rule again.
Strength. Speed. Reaction. Coordination. Endurance. Natural senses.
No combat technique hidden in the wording. No promise that wounds would close. No immunity to bullets, bad falls, hunger, anomaly rules, or his own decisions. The proposal did not make him something new. It raised the limits of systems already present and fixed the comparison to a version of himself that existed before the edit.
If he later asked to double the altered state again, the system would have to treat two hundred to four hundred percent as a new target with a new price. Repeating the same sentence could not silently purchase another identical forty-unit increase.
His right thumb hovered over the black number beneath his wrist.
The first edit had been made with a thing's hand on his shoulder. He had spent nineteen energy because the alternative was losing his face.
This time no one forced him.
That made the choice more frightening, not less.
Leo looked at the key stamped 4812 on the floor beside him. At the GBA registration strip protruding from his pocket. At the notes on his phone ending with Return home.
Waiting to remain unchanged would not preserve him. Meridian would make its own changes if he gave it enough time.
He chose ADD.
The number under his right wrist ignited.
Leo's arm locked straight. The black 81 sank toward the bone, each digit dragging a line of heat behind it. He tried to pull the arm against his chest and could not bend the elbow.
The heat reached his shoulder.
Then every muscle in his body contracted at once.
His back struck the island. His jaw snapped shut. Pain ran through his calves, abdomen, hands, and throat in one coordinated wave, too organized to be a cramp and too complete to escape by relaxing.
The room narrowed to the sound of his teeth grinding.
The 81 broke apart beneath his skin.
For a moment there was no number.
Then 41 surfaced in its place.
His body released him.
Leo folded forward, caught himself with both hands, and remained on the floor until the stone stopped seeming soft beneath his palms.
Air entered his lungs.
Too much of it.
He could feel the expansion between individual ribs. He could hear the scrape of fabric at his shoulder, water settling in the stockpot, rain striking different sections of the panoramic glass. The sounds had not become louder. They had separated.
The pressure behind his eyes opened one final panel.
INTERNAL RULE ADDED.
Current anomalous energy: 41.
Absorbed functions: 1/10.
The first circle on his left forearm still contained the tiny door. The other nine remained empty. No new mark formed.
Leo touched the cut inside his lip with his tongue.
It was still split.
His right arm still ached from both edits. Exhaustion remained lodged behind his eyes and across his shoulders. The rule had not healed him or replaced the sleep his body needed.
Good.
Not because pain was desirable. Because the result matched the words.
He waited for his breathing to steady, then rose carefully.
The careful part lasted one step.
He tested a fast rise with the force he normally reserved for standing while carrying a delivery. He shot upright too quickly and took two involuntary steps before his hip struck the edge of the island. His hand caught the counter before his balance failed, fast enough that he registered the fall only after he had already stopped it.
Pain bloomed along his hip.
Twice the capability did not mean twice the durability. Stone remained stone.
Leo adjusted his stance and tried again with less force.
His body obeyed.
He walked the seam in the floor. The small corrections that had required concentration now happened beneath thought. When he deliberately stepped off balance, his foot returned to the line before fear could tighten his stomach.
He lifted the full stockpot from the marked tile.
The weight had not changed. His relationship to it had. What had required both arms and bracing against his body rose cleanly to the island without touching him.
He set it down instead of testing how far he could throw it.
The spoon came next.
Leo balanced it on the counter, started the phone recording, and released it with his left hand.
His right closed around the handle almost immediately.
On the slow-motion playback, his fingers began moving while the spoon was still near the counter edge. Not before the release. Not by prediction. His eyes had registered the fall and his hand had answered in time.
He repeated the test twice. The result remained.
Ten push-ups no longer brought the tremor to his arms, although the old pain in his right forearm warned him not to turn proof into damage. His pulse rose more slowly and settled sooner. The smallest print on the painkiller packet remained clear from beyond the point where it had blurred before.
Leo stood in the center of the living room and listened.
Pipes ran through the walls in distinct vertical lines. Water moved somewhere several floors below. The beacon outside made a dry click beneath each pulse of blue light. Far beyond the fractured window, metal wheels crossed a gap in the city where no rails remained.
He was stronger.
Faster.
Still tired. Still hurt. Still holding a utility knife he did not know how to use in a fight.
But the next time a corridor collapsed, he might reach the safe side before the route closed. The next time a rule appeared while something moved toward him, he might gain one more second to read.
One second was not safety.
It was more than he had possessed before.
Leo picked up the apartment key and secured it inside the zippered pocket of his jacket. Then he checked the entrance chair, the water containers, and the line around the impossible footprint.
No second print had appeared.
The bedroom seal remained intact.
Only then did he notice the heartbeat.
His own was easy to identify: a hard, slowing rhythm inside his chest.
The second came from behind the bedroom door.
Leo stopped breathing.
The other heartbeat continued.
It beat once.
His heart answered a fraction later.
It beat again.
His answered again.
Not an echo. An echo followed its source.
This rhythm was leading him.
Leo touched two fingers to his throat. His pulse accelerated beneath them.
Behind the sealed door, the second heart accelerated first.
The paper strip between the door and frame did not move.
From inside the bedroom, Leo's voice said:
“Good. Now we're both stronger.”
