Dungeon Corpse Stacker: I Absorb Everything to Become Ominous Monarch

Chapter 188 - 189: The Secret Underground Laboratory under District 1



The industrial excavation lift descended through two miles of solid basalt and granite with a deep, rhythmic mechanical thrum that echoed off the damp shaft walls.

As the lift passed below the deepest ammunition vaults and star-iron storage bunkers of Sector Zero, the air outside the open-steel cage grew noticeably denser, colder, and heavy with the sharp, static metallic tang of ancient, dormant mana.

Renan stood at the front of the heavy lift platform, his dark woolen coat buttoned tightly to his throat, his pale hands resting calmly inside his pockets.

The twin-chambered core within his chest beat in a heavy forty-beat cycle, its twenty-eight thousand units of core density suppressed behind tight internal spirit locks, yet radiating enough passive gravitational mass to cause the condensation droplets clinging to the lift cables to freeze mid-air.

Behind him stood Thorne, his massive eight-foot combat frame anchoring the platform, his single amber optic sensor scanning the descending rock face with mechanical vigilance.

Beside Thorne, Chief Quartermaster Miller adjusted his spectacles while holding an encrypted tactical scanner, and Sylas watched the dark shaft above from the upper iron framework.

"The industrial drill bits shattered three hours ago when they struck the outer shell, Sovereign," Miller reported, his breath condensing into pale mist in the freezing subterranean air. "Our metallurgy team confirmed that the alloy surrounding the vault contains zero trace of terrestrial titanium or modern steel. It is a dense star-iron matrix woven with spatial dampening runes that predates the earliest recorded gate break in human history by thousands of years."

The excavation lift came to a smooth, hydraulic stop at the two-mile mark, settling onto a heavy steel platform erected inside a colossal natural cavern.

Illuminated by rows of temporary high-intensity floodlights, the far wall of the cavern was not composed of rough basalt stone.

It was a seamless, vertical bulkhead of dark, iridescent metal that absorbed the white floodlights like dry sand absorbing water.

In the center of the bulkhead sat a massive circular iris door, thirty feet in diameter, etched with intricate geometric runes that pulsed with an extremely faint, rhythmic silver light that matched the exact spatial frequency of the Mariana rift.

Thorne stepped off the lift first, his heavy metal boots clanging sharply against the steel floor plates as he approached the circular iris door.

"The mechanical locks are non-responsive to conventional force, Sovereign," Thorne reported, raising a massive gauntlet to touch the dark metal surface. "The door is not sealed with mechanical bolts or hydraulic clamps. It is held closed by a localized gravimetric lock that requires a minimum threshold of condensed core energy to disengage."

Renan walked past Thorne, stopping three paces from the ancient circular door.

He raised his bare right hand, extending his long, pale fingers until his fingertips brushed the cold, smooth star-alloy.

The moment his skin touched the metal, the dormant geometric runes etched across the iris door ignited with a brilliant, blinding surge of silver-violet fire that illuminated the entire subterranean cavern.

A deep, deafening sound of grinding stone and shifting star-metal echoed through the two-mile shaft as the ancient gravimetric locks disengaged.

The thirty-foot circular iris door rotated smoothly in a counter-clockwise motion, its heavy metal plates retracting inward into the surrounding bulkhead with a quiet, pneumatic hiss that released a cloud of preserved, bone-dry air that had been sealed away for millennia.

Sylas dropped silently from the lift superstructure, landing beside Renan with his void blades drawn, his optical visor set to broad-spectrum thermal and spatial detection.

"No biological or mechanical threat signatures detected inside the entryway, Sovereign," Sylas reported, his voice crisp and vigilant. "The atmospheric pressure inside the facility is completely stable."

Renan stepped through the open iris threshold, his dark woolen coat trailing behind his boots as he led his officers into the secret underground facility.

The space beyond the iris door was not a rough cave or a primitive stone tomb.

It was a vast, multi-tiered laboratory complex constructed from dark, unyielding star-metal, spanning over three hundred yards in length under a high vaulted ceiling lined with glowing crystal conduits that ignited automatically as the monarch entered the hall.

Dozens of towering glass containment cylinders filled with clear, stagnant preservation fluid lined the side walls of the main gallery.

Inside the cylinders sat the preserved fossilized skeletons and bio-mechanical fragments of ancient abyssal creatures whose structural anatomies far surpassed the complexity of the monsters emerging from modern S-rank gates.

In the center of the main gallery stood a massive holographic projector table forged from dark obsidian, surrounded by rows of terminal consoles built from the same iridescent star-alloy as the outer door.

Above the obsidian table, a three-dimensional star map constructed from floating violet light particles hummed softly, depicting the earth surrounded by an intricate web of dimensional fault lines that converged directly upon two specific points on the globe: the Mariana Trench in the Pacific Ocean, and the exact bedrock coordinates of District One.

Miller stepped up to the obsidian table, his eyes wide behind his spectacles as he stared at the floating violet star map.

"Sovereign... this laboratory was not built to study monsters," Miller whispered, his voice trembling with profound, unfeigned astonishment as he traced the glowing dimensional fault lines with his stylus. "This facility was built thousands of years ago to monitor and stabilize the dimensional crust of this entire planet."

Renan walked up to the central terminal console, placing his bare hand over the glowing control interface.

The holographic star map above the table shifted instantly, expanding to reveal thousands of lines of ancient technical schematics, spatial equations, and structural blueprints written in the primordial runic script of the abyssal lords.

Sylas’s optical visor flashed rapidly as his tactical gauntlet interfaced with the ancient database, downloading the massive stream of decrypted research files directly into Sector Zero’s central memory core.

"The decrypted logs reveal the true history of the peninsula, Sovereign," Sylas reported, his voice tight with focused intensity. "District One was never a random piece of coastal land. It was constructed directly above the primary terrestrial stabilization anchor designed to control the planetary gate networks."

Renan looked up at the floating blueprints, his violet eyes narrowing with cold, methodological precision as he recognized the structural diagrams of the massive crimson rift currently tearing open the bottom of the Mariana Trench.

"The humans in Geneva and the mages in North America believed that gates were random natural disasters that began thirty years ago," Renan spoke softly, his voice calm, level, and carrying a quiet absolute resonance that filled the ancient laboratory. "They believed that monsters were simply wild beasts spilling through tears in the sky."

He pressed his palm flat against the star-alloy console, causing the holographic blueprints to display the complete, unedited mechanism of the upcoming planetary gate breakout.

"The gates were never random disasters, Miller," Renan commanded, his voice dropping into a register of cold, terrifying clarity. "They are an automated planetary reset mechanism designed to purge the surface world when the dimensional core reaches total saturation. And the blueprint for that reset is sitting right before our eyes."

Miller stared at the scrolling equations, his face turning pale as he realized the sheer scale of the revelation.

The political wars, the financial blockades, and the guild rivalries that had occupied the human world for decades were nothing more than a blind, meaningless sideshow before the ancient, automated machinery sleeping beneath their feet.

Before Sylas could complete the data extraction process, a sharp, red warning glyph ignited across the center of the ancient holographic display.

The subterranean star-alloy laboratory vibrated with a deep, low-frequency hum as the ancient sensors embedded in the facility walls detected a sudden, massive spatial distortion detonating far out in the Pacific Ocean.

Sylas checked his tactical gauntlet, his visor flashing in solid, blinding crimson.

"Sovereign," Sylas reported urgently. "The deep-sea monitoring array reports that the Mariana Trench has just experienced its first physical structural breach. The crimson gate is no longer just leaking energy. It has begun spawning its first wave of Class-SS abyssal commanders."

Renan withdrew his hand from the terminal console, his dark woolen coat sweeping smoothly against his boots as he turned away from the obsidian table to face his officers.

"We have the blueprint, Miller," Renan commanded, his violet pupils glowing with sharp, unyielding light. "Extract every schematic file into our central database and return to the surface bridge. It is time to show the world how a Sovereign closes a gate."

As Renan led his officers back toward the iris door, leaving the ancient star-alloy laboratory behind in the cold, dark depths of the earth, the floating violet star map above the obsidian table flickered once, locking its final diagnostic vector directly onto the sovereign peninsula, setting the stage for the ultimate clash of Volume Two.
