Chapter 13: INDUSTRIAL DEAD ZONE
The metallic scent of industrial grease and stale rain clung heavily to the air of Sector 21.
Unlike the polished commercial core of Sentinel City, where high-speed mag-rail lines cut cleanly between towers of glass and neon light, this district had been forgotten. It was an industrial wasteland, a sprawling grid of decaying automated factories and hollow steel warehouses that had sat abandoned since the initial structural re-zoning seventy years ago.
Noah Kurtz adjusted the collar of his dark coat against the freezing midnight wind, his boots making a dull, heavy sound against the corroded iron walkway. Below him, rows of rusted cargo containers stretched across the gravel yards like a layout of giant, dead beetles.
A single holographic lantern flickered weakly at the entrance of a collapsed transit terminal, its yellow light casting long, unstable shadows over a security perimeter fence.

The pale blue system box floated across his vision, its dim light illuminating his steady, gray eyes.
Noah reached into his inner pocket and lightly touched the bronze hunter card resting against his chest. Beside it, the triangular obsidian fragment he had retrieved from the alleyway felt cold through his shirt, vibrating with a very faint, almost imperceptible frequency that matched the steady circulation of internal Ki within his spine.
"F-rank dungeon," Noah murmured to the empty yard, his voice flat. "Perfect."
He approached the steel turnstile at the perimeter fence. There were no armed guards here, no recruiters from major guilds, and no luxurious transport airships waiting to extract high-profile prodigies. High-yield organizations didn’t waste resources monitoring a site that offered nothing but low-grade essence stones and a high probability of structural collapse.
Instead, a solitary automated validation terminal hummed beside a localized spatial gate—a spinning vortex of heavy, translucent gray mist that physical light could not pierce.
Noah stepped forward, pulling his bronze card from his coat and sliding it cleanly through the scanner slot.
Beep.

Tracking Array: Initializing... Active.
The gray vortex rippled violently, the ambient atmospheric pressure around the turnstile dropping instantly as the gate recognized his license.
Noah didn’t look back at the distant, artificial glare of the city skyscrapers. He took a steady breath, checking the loose grip of the cheap utility knife inside his coat, and walked straight into the gray mist, letting the spatial transition consume his physical frame entirely.
The transition completed with a sharp, iron-like taste at the back of his throat.
Noah’s boots slammed down onto a floor composed of ancient, cracked flagstones covered in thick layers of dark moss and black ash. The air inside the catacomb was incredibly cold, thick with the suffocating stench of rotting sulfur and ancient stone. There were no modern energy lanterns or safety arrays here; the only illumination came from patches of glowing, bioluminescent blue fungi that grew along the vaulted, arched stone ceiling.
The structure didn’t look like a natural cave system or a standard dimension portal habitat. The walls were lined with massive, geometric pillars that had been carved out of dark basalt, covered in weathered, geometric engravings that had been smoothed over by centuries of complete neglect.

━━━━━━━━━━━━━━━
Noah stood perfectly still, his eyes narrowing as he looked down at his own legs.
The moment his card registered his entry into the dungeon, the Association’s automatic tracking array had begun broadcasting a slow, continuous energy ping from his bronze card to the external city server. If he moved too quickly or demonstrated an output of kinetic energy that didn’t align with an F-rank profile, the server would immediately flag his data for discrepancy.
"Let’s see if the record matches," Noah whispered.
He closed his eyes for a split second, drawing his awareness completely down into his legs and heels.
Circulate.
He activated [Ashen Step].
The microscopic thread of internal Ki within his meridians split smoothly, flowing down through his thighs and entering the specialized marrow channels of his calves. A high-frequency, completely silent vibration rippled through his lower muscles.
Noah opened his eyes and took a step forward.
His boot met the moss-covered flagstone. There was no sound. No friction. The physical resistance of the uneven ground seemed to slide around his stance entirely, his weight distributing across the shifting stone with impossible, liquid balance.
On his floating system interface, the metric tracker that recorded his physical output remained completely static, displaying the sluggish, low-efficiency numbers of an uncoordinated civilian. The technique wasn’t just hiding his presence from the monsters; it was literally masking the kinetic signature of his footsteps, turning him into a complete ghost within the Association’s monitoring grid.
A soft, scraping sound echoed from the dark corridor ahead.
Noah didn’t retreat. He didn’t drop his stance. He adjusted his posture slightly, leaning forward into a minimalist balance frame as three figures emerged from the shadows of the pillars.
They were low-grade iron cave ghouls.
The creatures stood roughly four feet tall, their hairless, ash-gray skin tightly stretched over emaciated, skeletal frames. Their elongated arms ended in jagged, black claws that dragged along the stone floor, making a sharp metallic scraping noise. Their eyes were completely hollow, covered in thick cataracts that could only sense motion and changes in temperature, while their jaws dripped with a sluggish, acidic saliva that hissed softly as it hit the moss.
"Screee...!"
The lead ghoul caught the sudden scent of human warmth, its jaw opening wide as its muscular legs coiled to spring.
To an average academy rookie or an E-rank supporter, three ghouls attacking simultaneously in a narrow, pitch-black stone corridor would be a scenario that required immediate panic and heavy defensive magic. But Noah just watched them with an absolute, chilling calm.
The perspective of The Ash-Walker ran through his brain like a cold current, calculating the exact trajectory of their bodies before they even left the ground.
The first ghoul launched itself forward, its long claws aiming straight for his face.
Noah didn’t swipe blindly. He didn’t activate any flashy elemental spells. He simply moved his right foot an inch to the side, executing a tiny, flawless slip-step using the Ashen Step to glide right through the blind spot of the monster’s vision.
The creature flew past his shoulder, hitting nothing but cold air.
In the exact same microsecond, Noah’s hand moved. The cheap steel utility knife slid out of his pocket like an extension of his own fingers. He didn’t push with raw physical strength; he allowed the momentum of the ghoul’s own jump to guide the blade.
Puch.
The steel point slipped perfectly into the narrow, unarmored space between the base of the skull and the first spinal vertebra—a precise, hidden neural node that standard academy biology books didn’t list.
Noah gave the handle a tiny, clockwise twist.
Circulate.
A microscopic spark of Ki traveled through the metal blade, disrupting the creature’s core neural transmission instantly.
The ghoul’s limbs went completely limp mid-air. It hit the stone floor with a dull thud, its gray body twitching twice before dissolving into dark gray dust, leaving behind nothing but a tiny, pebble-sized blue stone that rolled softly across the flagstone.
The remaining two ghouls let out a confused snarl, their gray heads turning toward the spot where their pack mate had vanished. They couldn’t understand how a target could move without causing a single vibration in the air or earth.
Noah stood in the shadows of the basalt pillar, his utility knife held loosely at his side, his thumb resting flat along the guard. His breathing remained perfectly slow, perfectly steady, while his steel-gray eyes remained fixed on the monsters before him.
"Two left," Noah said softly, pointing to the dark corridor.
He didn’t wait for them to charge this time. His body shifted forward, blurring into a silent, low-profile advance as he moved deeper into the ancient, forgotten stone vaults of the catacomb.
