The howling wind of the decompression wave dragged Danny Vance’s boots closer to the dark mouth of the pneumatic chute, the spinning blades of Chute 4-B's exhaust fan screaming below like a mechanical leviathan waiting to grind his flesh to pulp.

He had no traction. His Slick-Shoes, permanently fused to the tight black rubber of his Slipstream Suit by the searing heat of the border wall's laser grids, offered no grip against the warped concrete of the gantry. The air in the Sealed Maintenance Shaft was vanishing, sucked down the broken conduit by a massive, violent vacuum that rattled his teeth and threatened to collapse his lungs.

Every second was a physical trial. His left leg was a column of white-hot fire, the makeshift splint inside his suit grinding directly against his fractured femur with every micro-shift of his weight. His right shoulder, dislocated during his desperate block of the shrapnel, hung uselessly from his torso, a dead weight that sent a nauseating throb up his spine. His hand-assembled shortwave radio was a shattered ruin of wires and plastic against his ear, completely dead. He was entirely alone, cut off from Blind Bobby’s navigation and Silas Vance’s guidance.

*If I slide down that chute, I die,* Danny thought, his mind racing through the calculations of momentum. *But if I stay here, Vance’s guards will execute me. I have to find a vector out of this vacuum.*

Using his rigid, numb fingers—the synthetic skin grafts on his palms completely dissolved into raw, weeping dermis—Danny clawed at the manual pressure valves on the chest of his suit. He couldn't feel the metal dials; he had to watch his blood-smeared fingers clamp around the emergency release, relying on visual tracking alone. He forced his fingers to twist the valve, executing the Pressure Balance Method.

Pressurized fluorocarbon gas vented from his shoulder ports with a sharp *hiss*, equalizing the internal pressure of his suit with the rapidly decompressing chamber. The sudden drop in internal pressure caused his remaining skin grafts to blister violently, but it stabilized his core.

"Now," Danny rasped, his voice a dry, hollow rattle inside his Sovereign Respirator.

He stomped his heels together, activating his power and dropping his lower-body friction coefficient to near-zero. He didn't try to slide away from the vacuum; instead, he let the wind carry him toward the chute, utilizing the Vector Angle Calculus to align his trajectory with a massive, vertical steam conduit that ran parallel to Chute 4-B.

Just as his boots reached the lip of the decompressing chute, Danny deactivated his power.

He engaged Surface-Adhesion, stomping his warped chromium soles hard against the rusted iron pipe. Sparks erupted in a blinding, orange shower as the rough metal of his boots ground against the steel. The violent deceleration jerked his dislocated shoulder, forcing a choked scream from his throat, but his boots held. He clung to the pipe, his body suspended over the screaming exhaust fan as the vacuum wind roared past him.

Behind him on the gantry, Officer Vance’s guards struggled to maintain their footing, their heavy security armor making them easy targets for the decompression wave. Vance roared a command through his external speakers, but the words were swallowed by the deafening rush of air.

Danny didn't wait for them to recover. He released his grip, dropping his friction coefficient once more, and slid horizontally along the curved surface of the steam pipe. He moved like a shadow, slipping through a narrow maintenance hatch that led away from the decompressing shaft and into the deeper, silent corridors of Sector 7.

***

Ten minutes later, Danny collapsed in a narrow, dimly lit drainage conduit. He lay on his side, his chest rising and falling in ragged, shallow gasps. The air here was cold and smelled of ozone and chemical ice.

He raised his hands to his face. In the faint, flickering light of a nearby maintenance terminal, his palms looked like raw, weeping meat. The synthetic epidermal grafts Dr. Carter had applied were gone, dissolved by the extreme thermal friction of his near-sonic slide at the border. The dry, pressurized air of the mid-tiers was actively drying out his exposed dermis, causing his skin to crack and peel in large, painful sheets.

*I need the grafts,* Danny thought, his vision blurring from exhaustion. *If I don't get the military-grade shielding gel, my skin will slough off completely. I won't be able to slide. I won't be able to save Clara.*

The thought of his sister was the only thing that kept his heart beating. He could still picture her pale, frail form resting on the cot in Level 0, her veins glowing with the cold, blue light of the Delta-Strain mutation. He had sent the medicine down the chute, but his own survival was still unwritten.

He dragged his broken body forward, his left leg scraping against the cold steel of the conduit. Up ahead, the narrow pipe opened into a massive, vaulted chamber that hummed with a deep, low-frequency vibration.

Danny peered through the rusted grating of the exit.

He had reached the outer perimeter of the Liquid Nitrogen Depots.

The depot was a vast, subterranean cavern of sterile white concrete and frosted steel. Towering cylinders of liquid nitrogen stood like silent sentinels in the center of the vault, their surfaces coated in a thick layer of white frost. Frosted pipes ran along the ceiling and walls, venting thin, lazy plumes of freezing white vapor that settled over the floor like a dense, low-lying fog. A series of narrow, ice-coated metal catwalks suspended thirty feet above the pressurized storage tanks connected the various sectors of the facility.

This was the primary cooling hub for Sector 7's genetic research laboratories, and it was a death zone for Danny’s power.

*The cold,* Danny realized, a cold dread settling in his chest as he looked at the frosted catwalks. *Silas warned me. Extreme cold freezes the lubricating gels. It locks the joints instantly. If I lose my traction here, I’ll slip off the catwalks and fall into the nitrogen tanks below.*

But the depot was also where the corporate division stored its high-purity medical supplies, including the Synthetic Epidermal Grafts he desperately needed to treat his raw hands.

Because of the localized power drop caused by cutting the copper cables in the lower sectors, the automated security doors of the depot were glitching, their electronic locks cycling early. A heavy steel security door at the end of the catwalk was sliding open and shut in an erratic, stuttering rhythm.

This was his only window.

Danny squeezed his body through the drainage grate and stepped onto the narrow, ice-coated catwalk. The sudden, intense cold hit him like a physical blow. The air was so cold it burned his throat even through his respirator. Inside his suit, the remaining Fluorocarbon Radiator Fluid began to thicken, its viscosity rising as the temperature plummeted. His knee joints stiffened, turning his movement into a slow, agonizing crawl.

He had to move. He had to slide.

Danny stamped his heels together, dropping his lower-body friction coefficient, and launched himself into a slide across the catwalk.

It was a disaster.

The catwalk was coated in a thin, uneven layer of hard ice. In sub-zero temperatures, ice did not behave like a wet surface; it was dry, rough, and highly abrasive. Without a layer of liquid water to lubricate the slide, the warped chromium plates of his fused Slick-Shoes caught on the jagged frost.

His slide was rough and bone-jarring. Danny’s boots slipped sideways, his center of gravity shifting violently. He spun out of control, his body sliding toward the edge of the narrow catwalk.

*No!* his mind screamed.

He deactivated his power, engaging Surface-Adhesion in a desperate attempt to halt his momentum. His boots ground against the icy steel, throwing up a shower of frozen crystals. He slid to a halt just inches from the edge, his left leg hanging over the thirty-foot drop into the pressurized nitrogen tanks below. The violent stop sent a white-hot needle of pain up his fractured femur, nearly causing him to black out.

Danny lay on the catwalk, his chest heaving. His joints were locking. He could feel the cold seeping through the thin rubber of his suit, freezing the synthetic lubricating gel against his skin.

*I can't slide normally on ice,* Danny analyzed, his teeth chattering inside his mask. *The friction coefficient of dry ice is too high, and my gel is freezing solid. I have to use short, controlled bursts of speed. And I have to clear my joints.*

With a trembling, numb hand, Danny reached for the manual Coolant Flush Valve mounted on the chest of his suit. He pulled the lever.

*Hiss!*

A burst of warm, highly toxic Fluorocarbon Radiator Fluid flooded through the internal tubes of his suit, circulating around his knees and ankles. The intense heat cleared the ice from his joints, restoring a fraction of flexibility, but the cost was heavy. His HUD, flickering weakly, showed that his suit's coolant levels had depleted by forty percent. The sudden shift from freezing cold to intense heat caused a sharp, agonizing cramp in his knees—a mild joint calcification that made his legs feel like lead.

"Just a little further," Danny whispered, forcing himself to stand.

Using short, controlled bursts of speed, he glided across the catwalk, utilizing Surface-Adhesion to lock his boots to the metal every time he felt his balance slip. He moved from pillar to pillar, treating the icy catwalk like a series of short acceleration lanes.

He reached the security door. The heavy steel barrier was still stuttering, sliding open and shut with a loud, metallic *clack-clack*. Danny timed the rhythm of the glitch, sliding through the gap during a split-second opening and entering the central storage vault.

Inside, the air was even colder, a silent, white sanctuary of frosted cabinets.

Danny scanned the room, his eyes locking onto a row of sealed, blue cryo-containers labeled with the corporate insignia of the Bio-Genetic Division. Inside the transparent glass of the central container, several sheets of Synthetic Epidermal Grafts floated in a protective, glowing gel.

He approached the container, his raw, bloodless fingers trembling as he reached for the manual release latch. He couldn't feel the metal; he had to watch his fingers clamp around the handle, pulling it down with the last of his physical strength.

*Hiss.*

The cryo-container opened, venting a plume of freezing white vapor. Danny reached inside and pulled a sealed canister of the grafts free, clutching it to his chest.

But as the container’s seal broke, his body’s sudden heat adjustment—the warm radiator fluid still circulating through his suit—was detected by the vault’s highly sensitive thermal sensors.

A sharp, high-pitched klaxon began to blare through the chamber, its red warning lights flashing against the white concrete walls.

Danny gasped, his eyes widening in terror as a heavy, high-pressure valve directly overhead ruptured under the automated security system's lockdown protocol.
