The stench of the Ruin Zone was different down here in the gut of the abyss; it wasn't just rot, it was the smell of time itself decaying.
Kael's lungs burned, each breath tasting like copper and wet silt.
He didn't have the luxury of a stance.
There was no "form" taught by Master Aris that covered lying face-down in primordial muck while a Rank F Slasher Wolverine tried to turn your ribcage into a buffet.
The beast lunged, a mass of shadow and clicking claws.
Kael didn't think. He reacted.
The [Bone Blade] erupted from his forearm again, a sickening shuck sound—like a knife through leather—as it tore through his own skin to exist.
He didn't swing like a master; he flailed like a dying man.
The wolverine's teeth snapped inches from his throat, the sound like a gunshot in the cramped silence of the pit.
Kael shoved the jagged, ivory-red protrusion upward.
The impact vibrated straight into his marrow, a dull, agonizing thud that felt like his own arm was being hammered back into his shoulder.
Lashes of white-hot pain sparked behind his eyes as the monster's weight bore down, snapping the tip of his makeshift sword.
Chunks of calcified blood and bone splintered off, spinning into the dark.
Kael let out a sound that wasn't quite a scream—a guttural, desperate rasp.
He was losing.
The blade was unstable, vibrating with a frantic, dying heat.
Every time the wolverine's serrated claws raked against the bone, Kael felt the "cut" in his soul.
It wasn't just a weapon; it was his literal life force, brittle and screaming under the pressure of a predator that didn't know how to quit.
He rolled, the monster's claws missing his scalp by a hair's breadth, tattered fabric of his tunic fluttering away like dead leaves.
He was bleeding—real blood this time, not the system's fuel.
The world was spinning, a kaleidoscope of red eyes and black fur.
Then, the "Impulse" hit.
The System didn't speak. There was no helpful tutorial voice explaining the mechanics of combat.
Instead, Kael's vision suddenly fractured.
A thin, translucent line of neon-violet light streaked through the darkness, anchoring itself to a specific patch of fur just behind the wolverine's left ear.
It was a tether. A roadmap to a kill.
Kael's heartbeat slowed, thumping heavily against his cracked sternum.
He didn't understand what he was seeing, but his body—starved of hope and hollowed out by betrayal—latched onto the directive with religious fervor.
The wolverine gathered its hind legs for a finishing leap, its throat vibrating with a kill-growl that rattled Kael's teeth.
Kael didn't retreat.
He took a staggering step forward, intentionally exposing his left shoulder—the one Darius had already ruined.
The beast took the bait.
It launched, jaws wide, aiming for the "weak" side.
Now.
Kael dropped.
He didn't just fall; he pivoted on his good heel, the violet line in his vision turning into a solid, glowing bolt.
He felt the system draw on his remaining stamina, a cold vacuum sensation in his gut.
The [Bone Blade] on his right arm didn't just grow; it refined.
The jagged edges smoothed out into a needle-thin spike of condensed hemoglobin and calcium.
As the wolverine sailed over him, Kael thrust upward.
No, he didn't thrust—he guided the blade into the path of the violet line.
The resistance was momentary.
Then, a sickening squelch.
The spike sank deep into the soft tissue behind the ear, piercing the brain stem with surgical, accidental precision.
The silence that followed was absolute.
The wolverine didn't even whimper. It simply... stopped.
The massive body went limp in mid-air, its momentum carrying it over Kael to crash into the mud with a heavy, wet slap.
It twitched once, a reflexive jerk of a clawed paw, and then the crimson light in its eyes faded into dull, lifeless glass.
Kael stayed on his knees.
His chest heaved, each gasp a struggle against the gravity of his own exhaustion.
The [Bone Blade] began to liquefy, the solid bone softening and receding back through the slit in his forearm.
It didn't just disappear; it felt like it was melting back into his veins, leaving behind a trail of ice-cold fire.
He waited for the pain to return—the agony of the fall, the bite of the bridge.
But instead, the air around him began to shimmer.
[MISSION CONCLUDED: SURVIVAL.]
[TARGET ELIMINATED: RANK F SLASHER WOLVERINE.]
[INITIATING REGENERATION PROTOCOL... REMAINING MANA: 4%.]
It started as a pins-and-needles sensation in his toes, quickly escalating into a frantic, internal heat.
Kael watched, mesmerized and horrified, as the skin on his chest began to knit together.
The deep gashes from the wolverine's claws closed, leaving behind unblemished, pale skin.
Inside him, there was a series of muffled pops—his ribs realigning, the jagged edges of bone sliding past each other to fuse back into a solid cage.
The hole in his shoulder—the one Darius's blade had made—burned the brightest.
He felt the muscle fibers weaving themselves back together like a frantic loom.
Within seconds, the lethargy of blood loss evaporated. His mind cleared.
He stood up, his legs no longer trembling.
He felt... repaired. Not just healed, but factory-reset.
The mud on his face felt itchy now, a nuisance rather than a shroud.
"I'm alive," he whispered, the words sounding alien in the hollow tomb of the abyss.
He looked at his hands. They were steady. Too steady.
As if responding to his realization, the air in front of him curdled, weaving itself into a semi-transparent interface.
Unlike the flicking, cheap HUDs used by the mercenary guilds, this one felt ancient, its edges decorated with spectral carvings of weeping swords and faceless women.
[NEW ABILITY ACQUIRED: BONE BLADE (LEVEL 1)]

[STATISTICS: SHARPNESS - D | DURABILITY - F | CONSUMPTION - HIGH.]
[WARNING: PROLONGED USE MAY LEAD TO ANEMIA OR BONE DENSITY COLLAPSE.]
Kael squinted at the text.
It was a deal with a devil he hadn't met yet.
He swiped at the air, his fingers passing through the light like smoke. The screen shifted, the blue tint turning a deep, provocative rose gold.
[HAREM SYSTEM DETECTED: 0 / ???]
[CURRENT STATUS: DORMANT.]
[REQUIREMENT TO UNLOCK ADVANCED FUNCTIONS: ESTABLISH A 'BOND OF RECOGNITION' WITH A COMPATIBLE FEMALE WARRIOR.]
"Harem...?"
Kael's lip curled. The word felt like a joke.
He had just been betrayed by the one woman he thought he loved, thrown into a hole to rot by his "best friend," and now a magical window was telling him to collect wives like they were Rank cores?
"I don't need a harem," Kael spat at the empty air.
"I need a way out of here. I need a map. I need... revenge."
The system didn't argue.
It simply flickered, the words [BOND OF RECOGNITION] pulsing with a rhythmic, heartbeat-like glow.
It felt less like a suggestion and more like a biological necessity, an itch at the back of his brain that he couldn't scratch.
He turned away from the screen, looking back at the corpse of the wolverine.
He needed to move. If there was one of these things, there were dozens. And the smell of the kill would bring every scavenger in a five-mile radius.
He reached down to pick up a sharp piece of rebar from the bridge wreckage—he couldn't rely on the [Bone Blade] if it was going to collapse his skeleton—when he heard it.
Scritch. Scritch. Slide.
The sound was subtle, almost lost in the distant drip of water.
It wasn't the heavy, predatory thud of a monster. It was the sound of a boot on stone. A controlled, rhythmic movement.
Kael froze.
Every instinct he'd honed scavenging the Ruin Zone screamed at him to vanish into the shadows.
He retreated into the hollow of a jagged rock, his heart hammering against his newly healed ribs.
From the pitch-black mouth of a northern tunnel, a faint, rhythmic rasp echoed.
It was the sound of metal dragging against stone.
Slide... shhhkt. Slide... shhhkt.
A figure emerged.
The bioluminescent moss on the walls cast a sickly green light over a woman.
She was tall, but her posture was heavy with exhaustion.
Her armor—once a proud, polished silver—was dented, stained with the black ichor of monsters and the dark red of her own wounds.
One of her pauldrons was missing, and her left arm hung limp at her side.
In her right hand, she held a broken longsword.
The blade was snapped halfway up the length, the jagged edge leaving a shallow groove in the mud as she walked.
She stopped ten feet from the dead wolverine.
Her head tilted, her eyes scanning the area with a clinical, cold intensity that made Kael's skin crawl.
Her hair, a tangled mess of blood-matted sunset-orange, fell over a face that was strikingly beautiful and terrifyingly grim.
She didn't see him yet.
She looked at the wolverine, then at the hole in its skull.
"Messy," she muttered, her voice a low, melodic rasp that sounded like it hadn't been used in days.
"But efficient. Who's hiding in the mud?"
She didn't raise her broken sword. She didn't need to.
The sheer pressure of her presence—even in her battered state—felt like a physical weight pressing down on the cavern.
This wasn't a scavenger. This was a warrior.
Kael shifted his weight, and a small pebble skittered across the floor.
The woman's head snapped toward his hiding spot.
Her eyes—a piercing, icy blue—locked onto his.
"Come out, rat," she said, a faint, dangerous smile playing on her lips.
"Or I'll see if your neck is softer than that beast's."
As Kael stepped into the light, his vision didn't just see her.
The System interface exploded into a frantic, pulsing red.
[TARGET ACQUIRED.]
[NAME: SERA, THE FALLEN CAVALIER.]
[POTENTIAL: S-RANK SWORD-HEART.]
[WARNING: LETHAL INTENT DETECTED. CHANCES OF SURVIVAL WITHOUT BOND: 0.02%.]
Kael didn't look at the screen.
He looked at the broken sword in her hand.
"I'm not a rat," he said, his voice regaining its edge.
"And I'm not interested in dying today."
"Interesting," Sera said, her eyes dropping to the faint, sword-shaped scar on his forearm.
"Because the abyss doesn't take 'no' for an answer."
Before she could take another step, a deafening, earth-shaking roar tore through the tunnel behind her.
A wave of heat, smelling of sulfur and ancient malice, blasted into the clearing.
Sera didn't flinch.
She just tightened her grip on her broken blade.
"Well," she whispered, "it looks like our dinner guest has arrived."
Then, the floor beneath them began to crack.
[SYSTEM ALERT: BOSS ENCOUNTER INITIATED.]
[ABYSSAL TERROR: RANK D+.]
[CURRENT STATUS: UNPREPARED.]
[BOND STATUS: PENDING... TIME TO IMPACT: 5 SECONDS.]
Kael looked at the woman. She looked at the darkness behind her.
"Hey," Kael shouted over the rising roar.
"If we survive this, don't try to kill me."
Sera laughed, a harsh, jagged sound.
"Survival first, boy. Terms later!"
The ground vanished.
