Dungeon Corpse Stacker: I Absorb Everything to Become Ominous Monarch

The concrete dust hanging over the breached Capital Iron Wall had not yet settled when the sky above Sector 1 turned a suffocating violet-black.

Standing before the fifty-story glass-and-steel monolith of the National Hunter Association Headquarters, Renan stared upward. The towering skyscraper—once the absolute symbol of human authority and martial dominance—now stood isolated against the stormy sky. Siren alarms blared across the empty financial district, their piercing wails echoing off the deserted glass towers.

Behind Renan, three thousand five hundred dark, armored Shadow Knights stood in silent, immovable military formation. Flanking him were seven Rank-EX Shadow Commanders: Ignis, Elena, Sylas, Vance, and the newly extracted specters of the Three Pillars—Shadow Commander Jonathan, Shadow Commander Ronald, and Shadow Commander Beatrice. Their combined, corrupted mana signatures created an oppressive atmospheric pressure that cracked the surrounding glass storefronts and caused the asphalt beneath their boots to hum with dark energy.

Inside the glass monolith, the total mobilization protocol had been triggered.

[Association Defensive Protocol: Code Apex Active]

Facility: National Hunter Association Central Tower

Defensive Unit: 500 Executive Enforcers (Rank-A / Rank-S Automated Golems)

Structural Barrier: Mana-Dampening Tungsten Plating (Active)

Directive: Total Elimination of Monarch Threat Entity ’Renan’

Through the thick, reinforced glass of the lobby, two hundred Executive Enforcers—the Association’s elite internal security force—lined the marble floor. Clad in heavy, magic-resistant obsidian alloy armor and wielding high-density plasma halberds, they formed a dense defensive phalanx behind a wall of automated Class-S mana-turrets.

Renan didn’t pause. He didn’t issue a demand for surrender. He simply stepped forward, his dark coat swaying in the hot, ozone-scented wind, and raised his hand toward the massive, double-reinforced glass entrance.

”Clear the threshold,” Renan commanded softly.

Shadow Commander Jonathan—the extracted former Leader of the Three Pillars—stepped forward. The colossal, spectral figure raised a massive phantom war-hammer, its surface crackling with corrupted golden and violet energy, and slammed it directly into the skyscraper’s primary entrance.

BOOOOOOM!

The four-inch-thick, spell-reinforced glass doors along with the structural titanium frame didn’t just shatter—they were vaporized into a cloud of fine metallic dust and crystal shrapnel. The shockwave swept ninety feet into the grand lobby, instantly destroying the automated defense turrets and launching twenty Executive Enforcers backward into the polished marble pillars.

”Intruders breached the lobby! Fire! Open fire!” an Enforcer Commander screamed into his comms.

A volley of concentrated plasma bolts and high-density mana shells rained down upon the entrance, lighting up the lobby in a blinding display of crimson and blue explosions.

Renan walked calmly through the curtain of plasma fire, completely unbothered. Before a single energy bolt could touch his coat, Shadow Commander Ronald raised his spectral hands, deploying a wide-area Ominous Arcane Absorption Barrier that swallowed the incoming projectiles, converting the thermal kinetic energy directly into Renan’s reserve mana pool.

[System Log: Mana Converted]

Reserve Mana: +2,400 Points

Current Reserve Mana: 24,000 / 24,000 (Maximum Overflow)

”My turn,” Shadow Commander Beatrice whispered, her spectral voice whistling like a freezing winter gale.

The extracted Wind Monarch vanished from the doorway. A fraction of a millisecond later, green-and-black atmospheric blades slashed vertically across the entire lobby floor. SLASH! SLASH! SLASH!

In less than three seconds, sixty Executive Enforcers were disarmed and thrown off their feet, their heavy armor sliced open as if it were brittle cardboard. Before their bodies could hit the polished marble, viscous dark miasma burst from the floorboards, binding their limbs and suppressing their mana cores.

Renan stopped in the center of the ruined lobby, beneath the massive, three-story bronze emblem of the National Association. He looked up toward the central elevator shaft, where fifty floors of heavily fortified defense sectors separated him from the executive suite on the roof.

[Absolute Extraction System: Facility Scan]

Target Location: Floor 1 - 50 (Association Tower)

Floors 1 - 20: Administrative & Enforcer Quarters (Secured)

Floors 21 - 40: High-Tech Mana Testing Laboratories & Automated Defense Arrays

Floors 41 - 49: Executive Enforcer Captains & Vault Defenses

Floor 50: Presidential Boardroom & Class-S Relic Storage

”He locked down the central elevators and activated the internal mana-dampening fields along the stairwells,” Renan murmured, his golden eyes piercing through the ceiling tiles, tracking the heavy mana signatures concentrated on the top floors.

Behind him, Shadow General Ignis stepped into the lobby, its abyssal broadsword dripping with black dragon-fire that scorched the pristine white marble floor.

”They believe forty-nine floors of concrete and steel will buy them time to prepare their relics,” Renan said, a cold, razor-sharp smirk curving on his lips. ”Show them that space is irrelevant before the Sovereign.”

Renan raised his right hand, extending his fingers toward the ceiling. Deep within his chest, the Monarch’s core pulsed with absolute gravitational authority.

[Skill Activated: ’Sovereign’s Vertical Collapse’]

Target Area: Central Structural Core (Floors 1 through 49)

Force Vector: Upward Kinetic Vacuum

CRACK-CRACK-CRACK!

A terrifying groan echoed through the fifty-story tower as the steel reinforced elevator shafts and concrete floor slabs began to buckle inward. The atmospheric pressure inside the building spiked dramatically, shattering every exterior glass window from the second floor to the fortieth floor in a single, simultaneous explosion of glinting glass shards.

”Ignis. Sylas,” Renan commanded, stepping onto the central elevator platform as the gravitational field lifted the debris away. ”Pave the path straight to the top floor.”

Shadow General Ignis roared, leaping vertically through the collapsing elevator shaft with terrifying momentum, its flaming broadsword cleaving through steel girders and concrete floor slabs like a heated knife through butter. Beside it, Shadow Commander Sylas turned into a dark blur, darting along the vertical walls to execute any automated defense arrays before they could fire.

Floor 10... Floor 20... Floor 30...

The vertical invasion was not a battle; it was a disciplined, unstoppable execution. Enforcers stationed on the upper floors barely had time to raise their weapons before the floor beneath them dissolved into dark miasma, replaced by the towering forms of Rank-EX Shadow Commanders clearing the way for their master.

On the 49th floor—the final barrier before the Presidential suite—the steel vault doors groaned under immense kinetic pressure.

Renan floated upward through the hollowed-out center of the skyscraper, landing softly on the reinforced carpet of the 49th floor corridor. His golden eyes flared through the darkness, locking onto the final blast door guarding President James’s sanctum.

”Preserve the President,” Renan ordered softly to the commanders standing behind him. ”I want his soul extracted while he watches his empire burn.”
