Strongest Family System

Robert stayed beside the narrow opening in the stone without stepping through it.

A current of spiritual energy rose steadily from below, faint but unmistakable, brushing against his senses the way a distant breeze brushes against skin. Rather than descend blindly, he extended his own spiritual perception into the opening first, feeling the shape and quality of what moved through it. Then he asked inwardly.

"System, analyse the spirit flow."

Spiritual Quality: Stable.

Contains: Weak Spiritual Energy.

Origin: Deep Underground.

Estimated Connection: Large Underground Structure.

Recommendation: Continue investigation.

He studied the opening differently after that. This was not a simple crack venting stale air from some forgotten hollow. It was a passage carrying energy from something large enough and active enough to still be producing a spiritual aura after all this time.

Sai crouched at the opening's edge and ran two fingers lightly along its carved rim, reading the stone the way he read most things—patiently, without rushing to conclusions. Fine lines were cut into the rock in careful, deliberate strokes, forming what looked like the remnant of a formation node long since worn smooth by time.

They were not from the original construction. The monument above, the archive walls, and the carved characters throughout the settlement all carried the soft, rounded weathering of three thousand years. These marks were sharper.

This section stands out as being much younger than the rest of the place. It looks like someone came along and either reinforced or renovated this passage well after the original Keepers, who built the settlement, had faded away.

Whoever still walked barefoot through this sealed archive, leaving fresh flowers behind, was also responsible for maintaining whatever formation kept this spirit passage flowing.

Ronan stepped to the edge without hesitation, spiritual energy already gathering faintly beneath his feet.

"i will take a look," he said and dropped into the opening feet-first, his cultivation slowing his fall to an easy drift rather than a plunge. He descended for what felt like a long stretch of silence, his outline growing fainter in the dark below until even that disappeared.

He returned a few minutes later, rising back through the opening the same way he had gone down, his expression thoughtful rather than alarmed.

"It does not end on a floor," he said. "Twenty meters down, maybe more, and it just opens up. No walls close by. There was no ground beneath it that I could feel with my senses." He shook his head slightly. "Whatever's down there, it is big."

Nobody spoke for a moment. Robert turned the information over. If Ronan's spiritual senses—trained through months of foundation work and combat awareness—had found no clear boundary at that depth, whatever lay beneath them held real scale, not just depth but open space.

"System, estimate the underground structure."

Estimated Size: Unable to Determine.

Known Levels: Greater than One.

Recommandation: Continue investigation.

Greater than one level. The archive was not the underground structure. It was a doorway into something with genuine dimension, layered beneath the settlement in ways none of them had yet begun to map.

Eissa had kept working through the room while the others focused on the passage, and it was she who found the ledger, tucked inside a storage recess whose wooden fittings had long since rotted away, leaving only stone shelving and the thin plates that had rested undisturbed within it.

Unlike the Keeper's journal, written under clear emotional strain, these plates carried the flat, practical language of routine record-keeping. Short entries. Dates. Tasks completed in the plain tone of someone documenting maintenance rather than confiding fear.

Most of them had faded to the point where they were unreadable. However, a few were still legible enough to make out.

Formation inspection completed. Spirit channels were cleared. Guiding lamps are renewed. Seal energy is stable.

Generations of careful, unremarkable upkeep recorded the way any well-run clan might record its daily duties. The final legible entry carried a date that placed it almost exactly three hundred years past, matching everything the journal and the empty settlement above had already suggested.

It read only, "Primary Guardian has not returned."

Nothing followed. The remaining plates sat blank, the record simply ending there.

Robert read it twice before setting the plate down with care.

Whoever had stood at the head of this settlement's guardianship—the Primary Guardian, whatever authority that title carried—had vanished at the same moment the maintenance records stopped entirely. Whatever had emptied this valley of its people had taken its leader as well.

The system activated on its own while he was still turning the words over.

He read it without any visible reaction and accepted it silently, letting the notification fade before anyone noticed his attention had drifted. This was not something he intended to explain here, in a sealed chamber far from anyone who already understood what the system was.

Sai remained near the passage opening longer than the others; his head tilted slightly as though listening to something beneath the general stillness of the room.

"there is a rhythm to it," he said eventually, calling Robert back over. "The spiritual current is not constant. It rises every few minutes—just slightly—then settles again."

Robert extended his own senses into the opening and felt it for himself. A steady undercurrent of energy, and then, at intervals, a brief surge before it eased back to its baseline flow. Rhythmic. Patterned. Not the natural, irregular movement of ambient spiritual energy drifting through open stone.

It felt less like wind and more like breath—not the breath of something living in the ordinary sense but the operation of some vast and ancient formation still drawing energy through its channels the way it had been designed to, cycle after cycle, without anyone left to tend it.

"System, is this spiritual flow natural?"

Negative. Ancient Spirit Circulation Formation Detected. Operational Status: Active. Estimated Operation Time: Greater than 3,000 Years. Recommendation: Locate Formation Core

He read it a second time to be certain.

More than three thousand years. Whatever formation moved spiritual energy through this passage in that steady, cyclical rhythm had been active since before the Keeper settlement was even built above it. It had continued through the settlement's rise, through centuries of careful stewardship, through the sudden disaster that emptied it, and through the three hundred years since, untouched by all of it, still drawing breath in its own way, exactly as it had been formed to do.

Nobody spoke.

Almost in unison, the group came to a profound realization. This had never been a genuine ruin. Something lurking beneath Forgotten Moon City had been active all along, never pausing for even a moment in three thousand years, regardless of who was above or if anyone still remembered its true purpose.

Robert looked back into the opening, into a darkness that even Ronan's cultivated senses had not been able to fully measure.

Far below, at a depth impossible to judge, something shifted. A faint pulse of golden light rose briefly through the dark, therefore less than a heartbeat, and then it was gone, swallowed back into the black.

Nobody said anything.

Robert remained at the edge of the passage for a long while, looking down into a place that had carried its own quiet life for three thousand years and showed no sign, even now, of ever intending to stop.

Robert slowly withdrew his gaze from the darkness below.

The brief pulse of golden light had been real. Every person standing in the archive had seen it, yet none of them could explain what had produced it. It had not resembled the glow of spirit stones or the light emitted by ordinary cultivation techniques. It was calmer than that, almost restrained, as though something deep beneath the settlement had briefly stirred before falling silent once more.

Sai walked to the edge of the passage and looked into the darkness again, though he knew there was nothing left to see. After a long moment, he spoke quietly.

"If that light reached us from this depth, then whatever produced it must be far larger than we first imagined."

Robert nodded.

Everything they had uncovered pointed toward the same conclusion. The abandoned settlement above was only the surface. The monument, the archive, the Keeper records, and the hidden passages all existed for a single purpose—to protect or monitor whatever lay beneath them.

The true mystery had never been Forgotten Moon City.

It had always been the world hidden below it.

He looked around the archive one final time.

Every discovery they had made answered one question while raising several more. The Keepers had guarded this place for nearly three thousand years. Their final generation had vanished without explanation. Someone had continued maintaining parts of the ancient formation long after the settlement had fallen. Fresh footprints and a living flower proved that person—or whatever had replaced the Keepers—had been here only days ago.

Nothing about this place suggested abandonment anymore.

It suggested patience.

Robert turned toward the others.

"We've learned enough for today," he said calmly. "Rushing further without understanding what we're facing would only place us at a disadvantage."

No one disagreed.

Before leaving, Sai carefully copied the maintenance records and the final Keeper entry onto fresh jade slips taken from his storage ring. Eissa memorized the arrangement of the archive, while Ronan silently committed the location of every hidden passage to memory.

Robert took one last look into the endless darkness below.

Somewhere beneath that ancient settlement, beyond the reach of his spiritual senses, beyond even the System's current authority, something had continued existing for three thousand years.

And for the first time since arriving in Forgotten Moon City, he had the unmistakable feeling...

that whatever was waiting below already knew they were here.
