The chime of the global apocalypse announcement faded, but the structural vibration in the concrete foundation of Apartment 302 did not stop.
The ambient air in the second-floor unit smelled sharply of burned copper wire, evaporating ethanol, and the metallic tang of fresh blood.
Lynn Cross knelt on the worn linoleum floor of the kitchen, his senses expanding with unnatural, razor-sharp intensity.
Through the psychic link forged by the primordial soul-tether, a flood of cool shadow mana circulated through his vascular system, synchronizing his heartbeat with the small creature resting against his leather boot.
Through the tether, Lynn felt the rapid, rhythmic tremor of Nox's chest—two hundred and ten beats per minute, steady as an industrial timepiece.
The kitten’s amber irises were dilated until only a razor-thin crescent of gold framed pupils of fathomless black.
Every micro-vibration in the floorboards traveled up through Lynn's bare feet, translating into spatial coordinates: three tenants scrambling in panic on the landing above, the dry rattle of a deadbolt turning in Apartment 301, and the slow, heavy drip of water from a cracked cast-iron waste pipe in the wall cavity.
The changes hit his nervous system like an intravenous dose of liquid ice.
His vision sharpened; the dim shadows in the corners of the room resolved into crisp, high-contrast outlines as his retinas adapted to low-light wavelengths.
`[Soul Symbiosis Active: Sensory Synchronization (Stage 1).]`
`[Agility: 8 -> 11 (+3).]`
`[Perception: 13 -> 16 (+3).]`
`[Trait Acquired: Low-Light Darkvision (Basic).]`
Beside his knee, Nox sat completely still.
The coal-black kitten was no larger than a loaf of bread, weighing barely four and a half pounds, but its transformation was unmistakable.
Its jet-black fur seemed to absorb the dim grey daylight filtering through the blinds, and its unsheathed claws gleamed with an obsidian, metallic finish that bit cleanly into the floorboards without sound.
Its right ear—bearing that ragged, triangular notch from its former life as an alley stray—flickered toward the corridor.
A sickening crunch of splintering wood echoed from across the hallway.
The heavy pine door of Apartment 304 tore inward under immense, brutal pressure, showering the corridor with splintered timber and shattered hinges.
A tenant screamed—a short, strangled shriek that was violently cut off by the wet, sickening snap of a fractured femur.
A deep, wet snarl vibrated through the floorboards, accompanied by the wet tearing of meat.
It was Rex, the building manager’s prize guard Rottweiler.
In the past timeline, this animal had been a menacing hundred-and-ten-pound beast; now, under the violent catalytic pressure of the atmospheric mana storm, its cellular mass had mutated out of all natural proportion.
Its weight had doubled to over two hundred and twenty pounds.
Thick, calcified armor plates of dirty-gray bone had ruptured through the flesh along its spine and shoulder blades, forming a crude, jagged dorsal crest.
The floor beneath Lynn’s soles pitched with rhythmic, heavy thuds—each step delivering hundreds of foot-pounds of concussive force against the aged floor joists.
Its hide had split along the flanks, weeping viscous lymph fluid over dense subcutaneous muscle bundles that bunched and rippled like braided steel cables.
Its snout was elongated, split by multiple rows of serrated, needle-sharp teeth that dripped foul, foaming yellow saliva onto the cement floor, etching faint sizzling marks into the synthetic dust.
The beast had torn through two unlucky tenants in less than fifteen seconds.
Now, its armored, dinner-plate-sized paws turned on the slick concrete of the corridor, sniffing the heavy air.
It caught the scent of analytical-grade ethanol and fresh human blood wafting from the threshold of Apartment 302.
A guttural, chest-shaking growl built in its throat as heavy claw-falls began their deliberate, predatory march toward Lynn’s door.
Lynn remained frozen in a low tactical squat, his breathing measured and nearly imperceptible.
His mind processed the tactical geometry of the apartment building with icy clarity.
A normal Level 0 survivor, panicking at the sound of the beast, would have pushed bookcases against the door and prayed for rescue.
Lynn knew better.
A two-hundred-and-twenty-pound mutated canine possessed enough kinetic energy to batter through a residential hollow-core or pine door in three charges.
If the creature breached the apartment and entered the open living room, Lynn would have zero spatial advantage.
The beast's massive weight, speed, and jaw pressure would crush a human ribcage in a single glancing blow.
"Fight it in the open, and you die," Lynn whispered beneath his breath. "Control the choke point, and you control the beast."
He slipped forward on bare, silent feet, gripping the heavy-duty 24-inch high-carbon steel construction pry-bar.
You might be reading a pirated copy. Look for the official release to support the author.
At its chisel tip, two fresh #11 surgical scalpel blades were clamped flush against the steel with locking hemostats and tightly bound with industrial duct tape.
It was an improvised weapon, but forged with brutal efficiency: 4.5 pounds of rigid leverage terminating in a surgical cutting edge.
Lynn did not rely on brute strength alone; in a contest of raw tonnage, a mortal human possessed no mathematical leverage against two hundred and twenty pounds of kinetic mass.
He positioned the high-carbon pry-bar at an oblique thirty-degree angle between the hardwood threshold and the lower edge of the solid door.
By locking the steel crook against the heavy baseboard and driving his heel into the rear notch, he created a rigid mechanical triangle.
If the beast struck the door, eighty percent of the impact energy would transfer directly into the reinforced foundation beam rather than his skeletal frame.
Lynn reached the heavy door.
With infinite slowness, he pulled the heavy deadbolt back, easing the door inward just five inches.
He jammed his left steel-toed boot against the lower baseboard and braced the flat curve of the pry-bar into the floor seam, creating an unyielding, rigid mechanical stop.
The gap was barely five inches wide—narrow enough to admit a snout, but far too constricted for the beast's armored shoulders to clear.
*BAM!*
The impact slammed into the solid wood like an artillery shell.
The entire frame groaned, peeling centuries of white paint and plaster dust from the door casing, but Lynn’s braced posture held firm.
The mechanical triangle absorbed the shock wave, channeling the massive kinetic pulse deep into the subfloor without dislodging his footing.
The mutated beast let out a frenzied, guttural roar, blinded by bloodlust and ravenous hunger.
Sensing the open gap, the Rottweiler shoved its elongated, armor-plated head violently through the five-inch crack.
Its nostrils flared, blowing hot, rancid breath across Lynn’s face.
Its thick neck and massive skull wedged between the solid door and the reinforced steel jamb.
The jagged bone spurs on its shoulders caught against the outer molding, jamming its front half completely in the bottleneck.
The beast thrashed furiously, its rear claws tearing deep gouges into the hallway floorboards as it tried to force its bulk inward, snapping its yellow fangs within inches of Lynn’s knuckles.
"Nox, blind it!" Lynn barked the command through the mental link.
From the shadow of the doorway, Nox moved.
The small kitten did not charge across the floor; it dissolved into a blur of violet-black mist, utilizing [Shadow Step] to bypass the floor entirely.
It materialized directly atop the beast's broad snout, its four paws anchoring into the coarse skin.
With twin, instantaneous swipes of its unsheathed metallic talons, Nox slashed across the creature’s bulging amber eyes.
*Snikt! Snikt!*
Both corneas ruptured in twin spurts of viscous vitreous humor and blackish-red ichor.
The beast shrieked—a high, agonized howl of blinding fury—and reared its neck upward in a violent reflexive spasm.
That spasm tilted its massive skull back, stretching the thick, unarmored tendons beneath the ear cartilage taut against the door casing.
The anatomical weak point was laid bare for a fraction of a second.
Lynn did not waste a millisecond.
Channeling the full eleven points of his newly enhanced agility, he drove his body forward, shifting his center of gravity into the thrust.
Lynn’s surgical training kicked in with automatic, icy detachment.
The blade did not wander.
It aligned precisely with the narrow transverse gap between the occipital condyles at the base of the skull and the first cervical vertebra.
The #11 scalpel blade, ground to a razor-thin edge of tempered carbon steel, cleanly severed the rectus capitis muscles and sliced through the posterior atlanto-occipital membrane without meeting bone resistance.
*THWACK-CRUNCH.*
Then came the rigid mass of the high-carbon pry-bar’s chisel tip.
Four and a half pounds of solid forged steel followed the surgical path, plunging four inches deep into the cranial vault and puncturing the foramen magnum.
Lynn twisted the shaft ninety degrees with a brutal, wrenching flick of his forearms.
*Crack.*
The medulla oblongata was pulped instantly.
The beast’s frenzied thrashing ceased in mid-motion.
Its jaw clamped shut with a hollow clatter of teeth, its massive four-limb tremors shuddering once before going completely, totally limp.
The two-hundred-and-twenty-pound mountain of mutated muscle sagged forward, dead weight wedged tightly in the doorway.
Lynn exhaled a single, steady plume of white vapor into the cold air.
He braced his boot against the dead skull and pulled the pry-bar free with a dull suction sound, wiping the cerebral fluid clean with a piece of sterile gauze.
Beside him, Nox dropped lightly onto the top of the dead dog's head, licking its left paw with feline calm.
Then, the physical corpse began to dissolve.
Before Lynn’s eyes, the massive body collapsed into glittering swirls of dark-blue and violet aether particles, disintegrating into ambient mana.
When the light cleared, two objects rested on the blood-spattered hallway concrete:
A polished, thumb-sized hexagonal crystal glowing with faint smoky luminescence—a pristine [Tier-0 Standard Grey Shard].
And beside it, a heavy, foot-long chest forged from ancient, verdigris-coated bronze, wrapped in glowing chains of spectral light: a [Tier-0 Bronze Apocalypse Chest].
Simultaneously, a sharp, crystalline chime resonated directly within Lynn's auditory cortex:
`[REGIONAL ANNOUNCEMENT: Survivor Lynn Cross has claimed the Sector 04 First Blood!]`
`[Target Defeated: Mutated Bone-Spur Rottweiler (Tier-0 Elite Lv.1).]`
`[Achievement Unlocked: Regional Vanguard. Reward: 100 System Credits, Sector Reputation +10.]`
`[Experience Granted: Level Up! Lynn Cross: Lv.0 -> Lv.1.]`
`[Free Attribute Points Awarded: +2.]`
Lynn did not pause to celebrate.
Reaching down with quick, practiced hands, he scooped the heavy bronze chest and the hexagonal grey crystal into his apartment, slamming the solid oak door and dropping the iron security bar firmly across the frame.
He placed the bronze chest on the kitchen prep counter.
Touching the verdigris-covered latch, Lynn channeled a thread of his newly stabilized mana into the lock.
The glowing spectral chains hissed, dissolving into faint golden motes as the heavy lid popped open with a solid pneumatic hiss.
Resting inside on a bed of dark-violet velvet moss were three items:
Three sealed, thumb-sized glass ampoules filled with an effervescent, luminescent silver-blue fluid: [Refined Aether Extract x3].
Through the glass, the liquid churned with faint bioluminescent currents, exhibiting zero surface tension against the silica walls—a standard indicator of ninety-nine percent chemical purity.
And resting beside them, a heavy parchment scroll bound in braided silver wire, radiating concentric geometric arrays of optical runic circles: the [[Origin True Sight] Skill Book].
Lynn did not hesitate for a second.
He picked up the silver-bound parchment and pressed it firmly against his sternum.
"Learn," he commanded in a cold, steady voice.
The parchment dissolved into blinding silver light, surging up his carotid arteries directly into his optical nerves.
A cool, geometric sensation spread behind his eyelids as the system confirmed the integration:
`[Skill Learned: Origin True Sight (Tier-0 Passive/Active - Lv.1).]`
`[Ability: Perceive atmospheric mana flow lines, reveal hidden aetheric item stats, and identify biological structural stress points within 30 yards.]`
As the skill integrated, the visual field of Lynn's right eye shifted into spectral ultraviolet.
Faint, luminous azure ley-threads drifted through the kitchen air, swirling into miniature eddies where the ambient mana interacted with warm drafts from the steam radiator.
When he glanced down at his pry-bar, thin red stress vectors lit up along the steel shaft, marking micro-fractures in the metal grain where the tool had absorbed the dog's thrashing torque.
Down on Elm Street, a crescendo of frantic gunfire broke out, followed by the terrifying, synchronized howls of dozens of mutated pack beasts converging on 4th Avenue.
Outside Apartment 302, footsteps echoed from the stairwell as Marcus Vance and his thugs began their desperate, confused scramble.
Nox leaped silently onto Lynn’s left shoulder, its notched right ear twitching toward the window as its amber eyes glowed with steady violet fire.
Lynn looked down at his watch: 14:06 PM.
"The obelisk manifests in nineteen minutes," Lynn murmured, picking up his pry-bar.
"Time to clean out the street."
