Global Mutation: The Hunger System-Chapter 27: The Pressure At The Bottom

The transition from air to water was completely seamless.

Ren broke the surface of the black lake, plunging into the freezing depths of the flooded transit tunnels. Instinctively, his chest hitched, the human remnant of his brain screaming that he was about to inhale toxic, freezing liquid. But as the freezing water rushed into his nose and mouth, his newly upgraded Aquatic Adaptation hijacked his biology.

His lungs didn’t spasm. Instead, they processed the dissolved oxygen in the stagnant water with perfect, effortless efficiency. The bitter, paralyzing cold that should have induced hypothermia within minutes felt no more invasive than a cool autumn breeze against his hardened grey skin.

He was breathing. He was entirely submerged, and he was breathing perfectly.

Ren clicked on the waterproof military flashlight. The harsh, narrow beam cut through the gloom, illuminating a drowned world.

The water was thick with suspended silt, rust flakes, and the decaying detritus of the Old World. Leather briefcases, waterlogged shoes, and shattered glass floated in the zero-gravity environment of the subterranean tunnels. Ren kicked his legs, testing his mobility. The passive skill had completely nullified the kinetic drag of the water. He didn’t swim; he propelled himself forward with the smooth, frictionless speed of a torpedo, his movements displacing the water perfectly.

He left the platform behind, following the curving concrete tunnel deeper into the subterranean transit hub.

His Echolocation pulsed in a continuous, rhythmic rhythm, mapping the pitch-black environment far beyond the reach of his flashlight. The sonic feedback painted a massive network of maintenance shafts, electrical grids, and collapsed stairwells.

The silence down here was absolute. It was a heavy, suffocating quiet, broken only by the steady, rushing sound of water moving through his own expanded lungs.

Ren navigated the labyrinth for ten minutes, descending further beneath Zone Two. The ambient pressure increased exponentially, pressing against his Chitin Shell with the weight of thousands of tons of concrete and water. To a normal human, the pressure would have ruptured their eardrums and crushed their ribcage. To the Glutton, it was just a gentle squeeze.

A massive pair of reinforced steel doors loomed ahead in the beam of his flashlight. They were heavily damaged, buckled inward by incredible kinetic force, but a faded yellow sign remained bolted to the metal: Sector 4 - Primary Water Filtration & Treatment. This was the military’s objective. The quartermaster’s dossier required the extraction of the backup filtration cores.

Ren slipped through the jagged gap between the ruined doors, entering the facility.

The chamber was cavernous. Towering industrial turbines and massive cylindrical filtration tanks dominated the space. Thick, rubberized power cables drifted in the water like a forest of synthetic kelp.

Ren’s Echolocation spiked violently.

The sonic feedback didn’t return the elongated, reptilian shapes of the Trench-Gators. It returned a single, massive silhouette hovering near the ceiling of the flooded chamber. It was vaguely humanoid, but horribly stretched, its limbs ending in elongated, multi-jointed fingers.

The System overlay flared, burning a crimson warning across his retinas.

[Mutated Benthic Weaver (Lvl 12)] [Status: Ambush Mode] [Warning: High-Tension Neural Webbing. Extreme Piercing Threat.]

A Level 12 apex predator. The undisputed master of this drowned tomb.

The creature didn’t roar. It didn’t charge blindly like the gators. It simply detached from the ceiling, dropping silently through the dark water.

Ren swept his flashlight upward. The beam caught the horror for a fraction of a second. The Benthic Weaver possessed pale, translucent skin stretched tight over a skeletal frame. It lacked a lower jaw entirely; instead, its throat opened into a massive, pulsating ring of muscular teeth. Dozens of glowing, bioluminescent tendrils drifted from its back, casting an eerie, pale blue light across the rusted turbines.

The Weaver flicked its wrist.

Three of the bioluminescent tendrils whipped through the water with blinding speed. They weren’t soft appendages; they were razor-sharp, neurotoxic wires designed to slice through bone and paralyze prey.

[Skill Activated: Dash]

Ren fractured the space, teleporting ten feet to the right. The glowing wires sliced through the water where his chest had been a millisecond before, cleanly severing a thick industrial steel pipe in half. The metal sheared silently, thousands of tiny bubbles erupting from the cut.

Ren didn’t retreat. He utilized the frictionless environment, launching himself directly off the side of a massive filtration tank, rocketing upward toward the Weaver.

[Skill Activated: Rending Claws]

His ten-inch metallic scythes slid from his fingertips. Ren swung a lethal, cross-body arc aimed directly at the creature’s neck.

The Weaver possessed impossible agility. It contorted its spine backward, dodging the strike by a fraction of an inch. Simultaneously, it lashed out with its elongated, multi-jointed fingers, raking them across Ren’s chest.

SCREEECH.

The claws sparked against Ren’s Chitin Shell. The armor held, but the kinetic force knocked him backward, sending him tumbling violently through the suspended kelp-forest of power cables.

Ren righted himself, anchoring his boots against the concrete wall.

The Weaver was manipulating the environment. It swam rapidly in a wide circle around Ren, spinning a complex, invisible web of its neurotoxic tendrils between the rusted pipes and turbines. It was building a cage.

Ren watched the bioluminescent glow of the monster darting through the shadows. He couldn’t outmaneuver it in a complex, three-dimensional web. He needed to break the cage.

Ren closed his eyes, drawing a massive influx of oxygenated water into his lungs. He focused his mana, pooling the dark, violent energy at the back of his throat.

[Skill Activated: Psionic Scream]

He unleashed the telepathic shockwave.

In the open air, the scream was a devastating concussive blast. Underwater, physics magnified the violence tenfold. The psychic burst created a massive cavitation bubble—a vacuum of localized low pressure that expanded and collapsed in a thousandth of a second.

The resulting shockwave struck the chamber like a depth charge.

The water visibly distorted. The rusted turbines shattered, metal fragments spinning wildly into the dark. The Benthic Weaver’s neurotoxic web snapped instantly, the razor-wires dissolving under the kinetic crush.

The shockwave slammed directly into the Weaver. The creature’s translucent body shuddered violently. Its internal organs, unable to withstand the sudden, massive shift in pressure, hemorrhaged instantly. Pale blue blood erupted from its gills, clouding the water.

The monster went limp, spiraling downward toward the grated floor of the facility.

Ren didn’t wait for it to recover. He utilized his frictionless speed, diving straight down like a striking hawk. He landed heavily on the Weaver’s chest, pinning it to the metal grate.

He drove both hands downward, plunging his Rending Claws straight through the creature’s ribcage, bypassing the bone, and burying his blades deep into the pulsating, bioluminescent core in its chest.

The Weaver released a silent, final spasm.

[Target Dead: Mutated Benthic Weaver (Lvl 12)] [Experience Gained: 1200]

Ren stood over the corpse, the blue blood swirling around his boots in thick, oily ribbons. The hunger tore through his stomach, demanding the high-tier meat.

He used his claws to carve the glowing core from the monster’s chest cavity. It resembled a cluster of raw, pulsing nerve endings. He swallowed it whole. It tasted like battery acid and freezing ice.

[Gluttony Activated.] [Consumed: Bioluminescent Neural Core.] [Intelligence +4] [Perception +5] [New Skill: Neuro-Wire (Active)] [Description: You can secrete and manipulate a high-tension, razor-sharp filament from your fingertips.]

Ren raised his left hand. He flexed his wrist, and a thin, glowing blue wire slid from the tip of his index finger. It was as thin as a human hair, but when he casually brushed it against a nearby steel pipe, it sliced through the metal with zero resistance.

A deadly, localized garrote.

He retracted the wire, turning his attention back to the military’s objective.

Using his flashlight, he located the primary control console for the filtration system. Behind a shattered glass panel sat three cylindrical, sealed filtration cores. They were pristine, constructed from high-grade titanium and Old World purification technology.

Ren ripped the steel latches open, securing the three heavy cylinders. He strapped them tightly to the tactical webbing he had scavenged from the train car.

He had the bounty. He had the Black Tags secured.

Ren pushed off the grated floor, propelling himself back toward the ruined steel doors. He navigated the pitch-black labyrinth of the transit hub, retracing his sonic map with flawless precision.

Ten minutes later, he saw the faint, flickering glow of a flashlight penetrating the black water from above.

Ren broke the surface of the flooded tracks, the freezing water shedding effortlessly from his Chitin Shell.

Chloe was still sitting on the roof of the rusted commuter train. She had her pistol leveled at the water, her finger trembling on the trigger. When Ren’s ash-grey hoodie and dark hair breached the surface, she dropped the gun, burying her face in her hands in an overwhelming wave of relief.

Ren climbed the side of the train car, hauling the heavy titanium filtration cores onto the rusted metal roof. He wasn’t panting. He wasn’t shivering. He looked exactly as he had before he jumped in, save for the dark blue blood staining his jacket.

"You’re alive," Chloe breathed, her voice cracking.

Ren dropped the filtration cores at her feet. They landed with a heavy, metallic thud.

"I am the apex," Ren corrected softly, his violet eyes glowing in the gloom of the terminal. He looked toward the iron ladder leading back up to the surface. "Grab the cores. The sun is coming up, and the military owes us a place in the Inner Stadium."
