The forge did not welcome them.
It pressed them.
The moment Ren crossed the threshold, the air itself collapsed inward, slamming against his chest like a wall. His boots scraped across the metal floor as his body instinctively lowered its center of gravity, muscles tightening before his mind could even process the danger.
Heat flooded his lungs.
Not fire.
Weight.
— …Tch, Ren muttered, teeth clenched.
Behind him, the entrance sealed shut with a heavy clang. The sound echoed through the chamber, deep and final, like a verdict being delivered.
The forge was vast.
A circular hall carved entirely from dark steel, its walls layered with impact scars, dents, and fractures—each one the mark of something that had failed. Thick pillars supported a domed ceiling lost in shadow, chains hanging motionless as if frozen mid-swing.
At the center stood a massive anvil.
Cracked.
Split straight down the middle.
As if something had struck it once—and never again.
Gōrin stopped a few steps behind Ren.
His breath slowed.
His eyes narrowed.
— …So it's still standing, he murmured.
Saeko glanced at him.
— You've seen this place before?
Gōrin didn't answer immediately.
— Not this forge, he said at last.— But one like it.
Iori stepped forward, scanning the chamber.
— There's no visible mechanism.— No weapon racks.— No conduits.
His fingers hovered over his device, then froze.
— …I can't read it.
The forge responded.
The pressure doubled.
Ren's knees buckled violently as gravity surged downward, forcing him to one knee with a sharp metallic crack as the floor dented beneath his weight.
— Ren! Saeko snapped.
Ren grunted, one hand slamming into the steel to steady himself.
— Don't—!— Don't interfere!
Veins bulged across his arms and neck as his muscles swelled, instinctively pushing back against the crushing force. His body responded the only way it knew how—more strength.
The forge did not care.
The pressure intensified again.
Ren's vision blurred.
Sweat poured down his face, droplets striking the floor and flattening instantly, unable to roll.
— This isn't resistance, Gōrin said calmly.— It's judgment.
Ren snarled.
— Then I'll punch my way through it!
He forced himself upright, muscles screaming as he stood.
The moment he did—
The pressure spiked.
Time fractured.
Ren felt it before he saw it.
The world slowed.
The hanging chains froze mid-sway. A single drop of sweat hovered inches from his brow, trembling but unmoving.
Ren's breath stalled in his chest.
— …What the hell…
A resonance filled the forge—not a voice, not sound, but intent.
It pressed against his bones.
Strength breaks.Weight endures.
Ren laughed hoarsely.
— You've got a funny definition of endure.
He tried to step forward.
Pain exploded through his legs as the forge rejected the movement entirely, forcing him back down to one knee. His muscles expanded violently, fibers tearing microscopically under the strain.
Saeko took a step forward—
Gōrin raised a hand, stopping her.
— Let him fall, he said quietly.— Or he'll never stand.
Ren's fists trembled.
Images flashed behind his eyes.
Charging forward.Punching harder.Being the shield.Being the wall.
Always taking the hit.
Always believing that more power would be enough.
His fist slammed into the floor.
— Damn it!
The resonance returned—deeper, heavier.
You carry weight like an enemy.You fight it.
Ren's breathing turned ragged.
— Then tell me how I'm supposed to win!
Silence.
Then—
The pressure shifted.
Not weaker.
Redirected.
Ren felt it slide—down his spine, through his hips, into his legs. The crushing force no longer targeted his chest.
It tested his stance.
Gōrin's eyes widened.
— There… he feels it.
Ren inhaled slowly.
For the first time since entering the forge, he stopped pushing back.
He lowered his shoulders.
Widened his footing.
Let his weight sink.
The forge reacted instantly.
Metal groaned.
The cracked anvil trembled.
Ren stood.
Not explosively.
Not defiantly.
He stood correctly.
The pressure settled onto him—not as an attack, but as a load.
His muscles changed.
Not growing larger.
Condensing.
Strength folded inward, refined, stabilized. Each breath felt heavier—but controlled.
Time resumed.
The sweat droplet fell.
Ren straightened fully.
— …So that's it.
He stepped forward.
The forge did not resist.
He drew his fist back.
Not fast.
Not wild.
Perfectly aligned.
— Let's try again.
Ren struck the anvil.
There was no explosion.
No shockwave.
No roar.
The impact was silent.
The anvil did not shatter.
It yielded.
The crack sealed itself as steel flowed inward, reshaping, accepting the blow. A perfect circular fracture spread outward across the anvil's surface, controlled, contained.
The forge shook.
Then—
It bowed.
Symbols ignited along the walls, ancient glyphs burning gold as the crushing pressure vanished entirely. The chains rattled, falling limp. The air lightened.
Ren staggered back, breathing hard.
Something had changed.
Not his strength.
His foundation.
Iori stared, hands shaking.
— …The forge registered him.
Saeko smirked faintly.
— Took you long enough.
Gōrin crossed his arms, a rare hint of approval in his eyes.
— You stopped fighting the weight.
Ren clenched his fist, feeling the power settle naturally into his body.
— Yeah.
He looked at the restored anvil.
— I learned to carry it.
The resonance returned one last time—clear, final.
剛心 — Gōshin.The Heart That Bears All Weight.
The chamber walls split open.
Cold light poured in—sharp, vertical, unnatural.
A passage unfolded ahead of them, revealing a vast cityscape layered impossibly upward, bridges crossing empty air, structures stacked upon one another like compressed eras of civilization.
The Second Floor.
Ren stared.
— …You've got to be kidding me.
Saeko whistled softly.
— That's big.
Iori swallowed.
— System density is off the charts.
Gōrin stepped forward, eyes dark.
— This is where they decide who keeps climbing.
Ren cracked his neck, rolling his shoulders as the weight of the forge faded completely.
— Then let's not disappoint them.
They stepped into the light.
Behind them, the forge sealed shut—its purpose fulfilled.
Ahead—
The Second Floor breathed.
