The pit thrummed, a beast alive with noise, its concrete walls shaking under the afternoon's chaos. Sweat, blood, and smoke choked the air, thick enough to taste, as Jin stood in the center, chest heaving, knuckles throbbing from Makoto's fight. The crowd's roars crashed like waves, boots stomping, yen flashing in frantic hands, every shout a pulse against his skin. This was no mere gym, this was Seoul's underbelly, and Jin was here to carve his name, to build the Apex Syndicate one brutal fight at a time.
Across the pit, the gate creaked open, heavy and slow. A wall of a man stepped through, taller by a head, broader by more, his frame like poured concrete. Scars slashed across his chest, forearms roped with muscle, each step carrying the weight of a fighter who'd broken men and walked away. His taped fists flexed, knuckles cracking, as he rolled his shoulders, eyes locked on Jin, unblinking.
The crowd hushed for a heartbeat, recognition rippling through. "Holy shit," a man hissed, beer sloshing. "That's Gwan the Breaker, he's sent guys to the hospital." Another voice, low and eager, muttered, "This is gonna be good."
The announcer strutted on his platform, headset glinting under neon lights, voice booming through crackling speakers. "Ladies and gentlemen, our King of the Ring, the Apex, stands tall after smashing the Hammer, but now he faces a goddamn mountain! The bone-crusher, the grinder, GWAN!"
The pit exploded, cheers shaking the walls, gamblers shouting odds. Gwan didn't react, his gaze fixed, flat, predatory, like Jin was already meat.
Jin barely heard the noise, his focus narrowing, sharp as a blade. A flicker sparked at the edge of his vision. Golden text flared.
[System Notification: Optional Quest Available. Win the Tournament.]
[Reward: (1) Upgrade Card, (2) S-Rank Cards.]
He blinked, lips tightening. His ribs ached from Makoto's sledgehammers, bruises pulsing under his skin. Gwan was no lightweight, this was a man built to break. Jin couldn't tank hits, not from him. His eyes sharpened, resolve hardening. Fine, don't get hit, that's the only way.
The announcer's hand sliced the air. "FIGHT!"
The pit roared, a tidal wave of sound.
Gwan moved, not lumbering like his size suggested, but fast, precise, a predator closing in. His shoulders stayed tight, guard close, chin tucked, no wasted motion. This wasn't boxing, not street brawling, this was Close Quarters Combat, every move calculated to crush. Jin flicked a jab, testing range, but Gwan didn't bite, stepping in, eating space. His hands shot up, not to strike but to frame Jin's guard, shoving his balance back with brutal force.
Jin's feet slid, adjusting, but Gwan was relentless, a knee whipping up for his ribs. Jin twisted, the strike grazing his hip, shockingly fast, sending a jolt through his frame. That speed, from a man that size?
Jin's breath hissed, his Jeet Kune Do humming, urging him to flow. He ducked under an elbow aimed at his temple, the air shivering past, and circled out, feet light on the gritty floor.
The crowd roared, loving the chase, every dodge met with cheers, every swing of Gwan's arm with groans of anticipation.
"Get him, Gwan!" a woman screamed, won fluttering.
Jin's mind raced, sharp, clear. He's not a slugger, he's pressure, pure control, forcing me to move, to slip, to break. If I falter, I'm done. Gwan's forearm slammed into his chest, nearly toppling him, the pit's dirt floor scraping under his boots as he caught himself.
Jin darted in, snapping a cross at Gwan's chin, quick and clean. Gwan's wrist caught his, twisting hard, an elbow crashing toward his ribs. Jin jerked away, the strike grazing, air whistling. The crowd gasped, then cheered, the pit shaking.
Gwan pressed, a living cage, his arms framing, clinching, bumping, every move stealing Jin's space. A jab measured distance, not to hurt but to trap. An elbow sliced tight, aiming to shatter Jin's cheekbone. Jin wove, parrying with his forearm, but a hook slipped through, rattling his guard. A knee slammed his forearm, numbing it instantly, pain flaring like fire.
Jin's feet danced, side-stepping, weaving, his breath burning. Sweat slicked his skin, his arms heavy from blocking. Gwan was a tide, relentless, his strikes a blur, each one a hammer waiting to crush. Jin snapped a low kick into Gwan's thigh, the smack echoing, but the big man barely flinched, his eyes flat, unyielding.
The announcer laughed, voice crackling. "The Apex is slippery, folks, but Gwan's reeling him in! How long can he dance?"
Gwan barged forward, shoulder slamming Jin toward the pit's edge, the concrete wall looming. Jin shoved back, ducking a clinch, rolling to the side. He snapped another kick, aiming for Gwan's knee, but Gwan pivoted, absorbing it, his forearm crashing against Jin's chest again, forcing him back. The crowd screamed, "Break his ribs!" and "Don't fold, rookie!"
Jin's smirk flickered, sharp, fleeting. This was it, the fight he'd come for, the test he needed for the Syndicate. But his lungs burned, his ribs ached, every graze and block piling up. Gwan's forearm smashed his jawline, a short, crushing strike, heavier than anything Makoto had thrown.
The world tilted. Jin's knees buckled, crashing into the dirt, breath choking out. Black spots danced in his vision, spinning like fireflies.
"What the fuck," he muttered, head sagging, pain searing through his skull. That hit, it was a goddamn sledgehammer.
The crowd roared, triumphant, Gwan looming overhead, fist cocked, eyes cold as stone. The announcer's voice boomed, savage with glee.
"And down goes the King!"
The announcer's shout shook the pit, laughter and jeers exploding from the stands. Money flashed, spectators roaring with glee as Jin sagged on his knees, head bowed, Gwan looming like a guillotine.
"Down he goes!" a man bellowed.
"Gwan's gonna end him!" another yelled, grinning.
"Break him, Breaker!" The pit thrummed, a beast of sweat and bloodlust, neon flickering over the scarred concrete.
Jin's ears muffled the noise, the crowd's roars like waves underwater. His pulse pounded, ribs screaming, jaw throbbing, vision swimming with shadows. His body refused to move, knees sunk in the dirt, hands trembling, barely holding him up. His breath rattled, sharp as broken glass. Move, his mind screamed, but his limbs betrayed him, heavy, unresponsive.
A flash seared his vision, blinding white drowning the pit. Golden text burned.
[Warning. User in Danger. Critical Condition Detected.]
[Forced Awakening Protocol: Activated.]
Jin's eyes widened, weak, his chest heaving. A fire sparked in his veins, slow at first, then surging, heat rippling through his blood, igniting his arms, legs, skull. His muscles twitched, convulsing under his skin, rewiring themselves.
"Ghhh," he choked, teeth grinding, sweat pouring, stinging his eyes. The crowd saw him seize, thought he was breaking under Gwan's punishment, but inside, something else stirred.
A new window flickered.
[Instinct Card: Engaged.]
Relief flickered, the card his lifeline before. But then the screen spasmed, gold and blue shattering into static, twisting into jagged black and bleeding red pixels. The card reformed, only to fracture again, glitching wildly.
"No, wait," Jin rasped, voice cracking, hands clawing the dirt, head lolling. He reached for the System, for clarity, but the glow warped, violent, unnatural. The Instinct Card pulsed, its light wrong, sick, hungry.
[Ultra Instinct — Corrupted]
The description below a mess of scrambled symbols, jagged lines that burned his eyes to read.
What the fuck is this? Jin thought, his mind hollow, echoing. His consciousness slipped, like hands shoving him into darkness, something alien rising in his place. His breath stuttered, his body no longer his own.
His head dipped, sweat dripping, pattering on the dirt. His hands stilled, muscles quieting, unnaturally calm. Slowly, deliberately, he rose, limbs unfolding with a fluid ease, no strain, no fight. His spine straightened, shoulders slack, like water filling a vessel.
The crowd's roar died, silence gripping the pit.
They thought it was desperation, a rookie's last stand, but Jin's movements were wrong, too smooth, too lifeless. Gwan frowned, his first sign of doubt, his stance tightening. He'd broken men, felt their spirits crack, but this, this wasn't that.
The announcer's laugh faltered, voice wavering. "And, uh, he's back on his feet, folks?"
Jin's head hung low, chin dipped, breathing steady, too steady, an eerie rhythm. His arms dangled, loose, lifeless. Then his neck creaked, tilting slightly, the sound sharp in the silence, like a predator sizing up prey.
Gasps rippled through the stands. A woman whispered, "What the hell's wrong with him?"
Jin's eyes lifted, and the crowd froze. The whites were gone, swallowed by black sclera, a void where humanity should be. His irises glowed faintly white, dark purple coiling in their depths, a storm trapped in glass. Someone screamed, the sound swallowed by unease.
Inside, Jin floated in a black sea, his voice echoing into nothing, clawing for control but finding no anchor. Through the haze, he saw his body, upright, limp yet composed, head cocked, eyes glowing like a demon's.
The announcer's voice cracked, panic bleeding through. "Our, uh, King of the Ring is back, but what, what is this?"
The crowd whispered, tension thick, no longer cheering, the spectacle turning unnatural. Gwan stepped back, fists raised, every instinct screaming danger. He'd crushed men, but this thing before him didn't feel human, didn't feel broken.
Jin, or what wore his body, raised its head fully, eyes locking onto Gwan. No smirk, no fire, just a void in flesh, a flicker of hunger in that purple glow. The pit waited, silent, breathless.
