The Weapon Genius: Anything I Hold Can Kill-Chapter 182: One Night (Part Four)

The rumble hit like distant thunder, vibrating through the walls of the south wing. Dust shook loose from old ceiling vents, and half the prisoners lounging around looked up from their dice games and crude arm wrestling contests.

"...What the hell was that?"

Seul paused mid-step, her brow tightening.

From somewhere above—far north—a muffled crash echoed again, more distinct this time. A few of the inmates started to rise. Some whispered. Others, already on edge from the earlier warning about possible intruders, moved faster.

"Yo, did they say something was happening in the north sector earlier?" a bulky guy grunted, pushing off the wall and heading for the nearest stairwell. "Whats with all this noise so late."

"Nah, there was no announcement," another barked—but he was already standing, eyeing the path northward. And then—

A sharp whistle cut the air.

Across the corridor, a tall woman in a grey-marked jumpsuit stepped onto an overturned bench, her voice booming.

"All squads stationed on South 2, converge on the northern flank. Now. Leader’s orders."

That was all they needed.

The entire hallway came alive. Prisoners who had been playing it cool seconds ago surged toward the stairwells and doors, many unsheathing their weapons or summoning gear mid-run. The air thickened with noise—boots, curses, metal scraping on concrete.

Chul clenched his fists. "They’re gonna flood the north wing."

"They think the threat’s only there," Hanseong said calmly.

"Then this is the time," Seul said, already unfastening the front of her disguise. "We start now. Keep them split."

The last of her words were punctuated by the shimmer of system particles taking off her false uniform.

A guard who turned too late caught a wave of gravitational force to the chest. His body arched upward—weight turned sideways mid-air—before slamming against the wall and dropping limp.

Chul moved in behind her, driving his heel into the floor. A split-second later, the kinetic release blasted outward like a ripple, catching a group of runners and hurling them back like rag dolls.

Hanseong didn’t speak. He moved.

His blade drew clean—silver steel glinting as he carved through the sudden chaos. Not to kill—he aimed for pressure points, limbs, disabling without excess. Prisoners shouted, stumbled, scrambled.

Someone screamed. Another threw what looked like a barbed spear—but it bent mid-flight, crushed under Seul’s expanding gravity field.

The corridor transformed into a full warzone within seconds.

"South wing under attack!"

The words echoed down the stairwell.

Too late.

More prisoners poured in.

Unlike the rest of the prison’s chaos, this wasn’t a simple brawl anymore. They were organized now, aware. A few of them wielded real weapons—system-issued or artifact class—and even the ones who didn’t were already beginning to synchronize.

"You see this?" Chul grunted, ducking a thrown axe and cracking the floor open beneath another attacker’s feet. "They’re holding back."

Seul’s gravity field surged again, forcing half a dozen to the ground—but more took their place. "They’re trying not to destroy their base."

"They’re pros," Hanseong said, flicking a shadow-slicked blade around an incoming chain. The weapon hissed past his ear, striking the wall behind him.

He didn’t flinch.

Seul exhaled. "Good thing we are too."

A metallic hiss snapped through the air—faster than sound.

Seul spun.

Something red and gleaming arced toward her neck. Thin as a whip, shaped like a fluid chain.

Before she could react, Hanseong stepped into its path.

His blade caught it—barely.

Sparks flew. The air cracked.

Hanseong was forced back a half-step from the pressure, his katana vibrating under the strain.

Across the corridor, standing calmly between the bodies, was a woman draped in a high-collared jumpsuit with burnished crimson accents. Her eyes were unreadable. Her expression still.

She said nothing.

But the chain—that whip of shifting metal—retracted toward her wrist like a snake slithering home.

Seul’s breath caught. She hadn’t sensed a thing. No approach. No hostile intent. Nothing.

That’s not possible, she thought.

Hanseong didn’t speak.

The woman began to step forward.

Seul raised a hand, energy coiling.

"No," Hanseong said firmly, keeping his stance centered, blade low but ready.

He didn’t glance back at them. "I’ll handle her. You two—go."

Seul hesitated. "You sure?"

"Yeah. It would be smart to split up from here to make it harder for them to possibly stop us and cause more damage." 𝓯𝓻𝒆𝙚𝒘𝓮𝙗𝓷𝒐𝓿𝙚𝒍.𝙘𝓸𝙢

He didn’t wait for her to agree with him.

He stepped forward.

His blade gleamed under the lights—no aura, no posturing, just steel and breath.

"Go," he said again.

Seul didn’t like it. Not one bit.

But she nodded.

Her hand clutched Chul’s sleeve.

They turned and broke off, Seul pulling a gravity bend to vault them over a crumbled ledge and deeper into the corridor, leaving Hanseong behind.

Behind them, the woman’s hand shifted, the chain uncurling like a tongue from her palm.

Hanseong rolled his shoulders once.

"Didn’t think I’d see you again, sister."

The woman stepped forward, lowering the hood of her jagged-collared jumpsuit. Her hair was tied back now—sharper than he remembered—and her eyes held none of the warmth they once did.

"Well," she said, one shoulder rolling with casual force. "You always did know how to show up where you weren’t wanted."

Hanseong didn’t move, blade held low but poised. His eyes flicked briefly to her belt—still wrapped in steel cords, the unmistakable glint of a chain whip hidden beneath the folds. A legendary-grade handle rested at the base, gleaming in faint pulses.

"You’re working for them now?" he asked.

"I’m not working for anyone," she replied. "I’m here because I chose to be."

"And you chose this?" His voice didn’t rise, but the disappointment in it cut sharper than any blade. "Running with criminals, taking over ruins, pushing others down just so you can play queen of the ashes?"

Her mouth twitched into a grin. "Everyone’s building empires now, oppa. You just chose the boring side."

"There’s still time," Hanseong said, stepping forward. "Come with us. I don’t know what happened after the collapse—but I know you. You’re not like this."

She laughed once, dry and sharp. "I found people who took me in. Who didn’t care who I used to be. This place is my home now. These people? My family. So don’t take it personally when I break your legs and burn your friends down to the ground."

Hanseong’s blade twitched.

"None of them are my friends."

She tilted her head.

"Not all of them, anyway," he continued. "But I owe some of them. That’s enough."

She rolled her neck again and stepped sideways, circling now—slow, coiled, ready. "Owe someone enough to fight me?"

He didn’t answer.

"I remember your footwork from when we dueled each other," she said, her fingers brushing the chain hilt at her hip. "All straight-line offense. You still can’t pivot worth a damn, can you?"

"That was long before the system ruined everything and I’ve been trained since then," Hanseong said.

"By who?"

He exhaled. "Someone who’s a hell of alot better than you."

"Really now?" She clicked her tongue, then suddenly flicked her hand.

The whip shot out with a snap, its segmented links flashing in the low hallway light. It curved mid-air, razor-edged and fast, but Hanseong was already moving. His blade met it clean—a sharp clang ringing out as steel met steel—and he pivoted, deflecting the second lash before it could wrap around his arm.

Her eyes narrowed.

She struck again, faster this time. The whip coiled low, aiming for his legs, but he jumped, kicked off the nearest wall, and landed just far enough to avoid the rebound. The moment his boots touched ground, she was on him again, whip whirling like a storm.

Hanseong ducked under one strike, then stepped inside the second—his katana slicing at her exposed side. She turned with it, letting the whip drag her into a spin that carried her away from the arc.

Not bad.

Definitely not rusty.

She smiled, more impressed than annoyed. "You’ve improved."

"Had time to," Hanseong said, adjusting his stance.

"But not enough." She planted her feet, and her arm snapped forward again—this time the chain moved differently, its runes lighting up in staggered flashes. The whip split mid-strike into three separate arcs, all aimed from different directions.

Hanseong’s eyes tracked them. A beat passed.

And then—

One step. One breath. Three slashes.

Each precise. Each timed perfectly.

The chains deflected, redirected. One even rebounded into the wall behind her with a snap.

She whistled, genuinely surprised. "Okay. I’ll admit it. That was clean."

"You haven’t seen anything yet," he said, breathing steady.

She twirled the whip around her wrist and let it fall loose again, slower now. "You’re good. Better than I remember. But no way you’re handling this."

The whip began to hum. A low, pulsing thrum of power that spread out like a heartbeat.

"Because this..." she said, her voice dropping as the runes along the chain turned crimson, "isn’t just metal and edge."

Hanseong didn’t flinch.

"You’re not the only one who’s trained," she went on. "You’ve been dodging tricks. This isn’t a trick."

He tightened his grip on his katana.

She pointed the tip of her chain toward the floor. "This weapon has a special skill called Iron Pact. Every strike that lands will weigh you down. Every movement you make will slow. And when you fall..."

The hallway shook faintly with pressure as the weapon pulsed.

"...you stay down."

He didn’t back away.

Didn’t blink.

Only lowered his blade slightly, and said evenly, "Then I’ll just have to make sure none of your hits land."

Her eyes widened slightly—just a flicker—before narrowing again, focused.

"You really think you can stop me without even using your skill?"

He exhaled slowly, grounding his stance.

"Hell yeah."

And just like that, the hallway stilled.

Tension wound in the silence, sharp as steel.

They stared each other down—siblings standing on opposite sides of a war neither had chosen, both about to show just how far they’d come.

And the real fight had only just begun.
