Seo Rin was screaming.
Not in pain.
In fragmentation.
Her body wasn't tearing apart the way flesh normally did. It was folding inward, collapsing around invisible points as if reality itself had decided she occupied too much space. Blood floated away from her skin in thin red threads, suspended midair by Zero's presence.
Crimson held her desperately, arms locked around her collapsing frame.
"No," he snarled. "No—stay with me. Stay real."
The Cultivation of Sin surged violently, pain flooding every channel, every carved rune igniting at once. Crimson forced agony inward, trying to anchor Seo Rin the same way he anchored himself—through suffering, through refusal.
It didn't work.
Her breath hitched.
Her eyes lost focus.
"Crimson," she whispered, voice echoing strangely, like it was coming from far away. "I can't… feel my hands."
He pressed his forehead against hers, teeth clenched so hard they cracked. "You're not allowed to leave."
Above them, Correction Unit Zero observed.
Secondary anomaly degradation progressing.
Shen Tai shouted, panic cracking his carefully composed voice. "Stop this! She's irrelevant—she changes nothing!"
Zero turned its head slightly.
Incorrect.
The word hit the battlefield like a verdict.
Emotional interference introduces non-linear instability.
Crimson looked up, blood streaming down his face. "Then take me instead."
Zero regarded him.
You are already scheduled.
Seo Rin laughed weakly, blood bubbling from her lips. "Figures… Heaven's timing was always bad."
Crimson shook her gently. "Don't joke."
"I'm not," she whispered. "I'm scared."
The word broke something inside him.
Zero extended its hand again.
The pressure intensified.
Seo Rin's ribs collapsed inward with a sickening crunch. Crimson screamed as he felt it through her body, through the bond forged by shared blood and survival.
He did the only thing left.
He let go.
Not of her.
Of restraint.
The Cultivation of Sin detonated—not outward, but downward, compressing into the voids Zero had carved inside him. Pain became structure. Madness became alignment.
Crimson stabilized.
Something inside him snapped into place.
He stood.
Still holding Seo Rin.
Zero paused.
Deviation state altered.
Crimson felt it then.
Not power.
Weight.
The attention of something deeper than Heaven.
Something that existed before correction needed permission.
Crimson raised his head and spoke—not to Zero, but to the sky itself.
"You made rules," he said hoarsely. "You made failsafes. You made prophets."
His voice carried across the frozen battlefield.
"But you never made consent."
The sky responded.
Not with light.
With silence so deep it swallowed sound.
Shen Tai staggered back, face drained of color. "No… that layer isn't supposed to—"
Zero's posture shifted.
External interference detected.
For the first time since its awakening—
Correction Unit Zero took a defensive stance.
Seo Rin convulsed violently.
Crimson felt her slipping again, faster this time.
"No," he whispered. "Not like this."
Her fingers twitched weakly against his chest. "Listen to me," she said, forcing the words out through shattered breath. "You don't get to save everyone."
"I don't care," he growled.
She smiled faintly. "That's why they're afraid of you."
Her eyes met his, steady despite the collapse.
"You promised… to make Heaven choose."
Crimson swallowed hard.
"I choose you."
Seo Rin shook her head slowly. "Too late for that."
Then she did something unexpected.
She pushed him.
Not physically.
Existentially.
She severed the anchor.
The runes carved into her flesh—mirrors of Crimson's own—flared once, then burned out.
Seo Rin tore herself free from his hold.
Crimson screamed her name.
Zero reacted instantly.
Anomaly self-terminating.
Seo Rin turned toward Zero, blood floating around her like a crown.
"If Heaven needs a price," she said softly, "take something that hurts."
She smiled at Crimson one last time.
"Live long enough to regret it."
Then she stepped forward—
And vanished.
Not erased.
Exchanged.
The pressure disappeared.
The battlefield crashed back into motion violently. Suspended attacks slammed into the ground. Cultivators screamed as formations collapsed chaotically.
Crimson fell to his knees, clutching empty air.
"No," he whispered. "No… no…"
Zero stood motionless.
Transaction recorded.
Shen Tai stared at the space where Seo Rin had been, horror overtaking his expression. "What did you do?"
Stabilization achieved, Zero replied.
Primary deviation preserved. Secondary anomaly consumed.
Crimson slowly raised his head.
His eyes were empty.
Not hollow.
Clear.
"You took her," he said quietly.
Zero did not deny it.
Crimson stood.
The world felt… thinner now.
Easier to bend.
"You said you remove instability," Crimson continued. "She was the only thing keeping me human."
Zero tilted its head.
Assessment updated.
Crimson smiled.
It was not sane.
"Congratulations," he said softly. "You just made me cheaper."
Shen Tai backed away, fear finally overwhelming control. "This wasn't the plan. Heaven didn't authorize—"
Crimson turned toward him.
Every cultivator who met his gaze felt it.
Not killing intent.
Finality.
"You sold peace," Crimson said calmly, "by spending lives that weren't yours."
He stepped forward.
The ground cracked beneath his feet.
"I'm going to refund you."
Shen Tai screamed for guards.
None moved.
They were all staring at Crimson.
At the thing Heaven had failed to erase.
Zero spoke once more.
Deviation approaching irreversible state.
Crimson nodded. "Good."
He looked at the sky.
"I hope she was worth it," he whispered.
Above them, Heaven reevaluated priorities.
Correction Unit Zero remained active.
But for the first time—
It no longer knew if containment was possible.
