Darkness swallowed everything.
No ground.
No sky.
Only—
THUMP.
Muyeon opened his eyes.
He wasn't in the cavern anymore.
He stood in a void.
Black.
Endless.
"…A mental domain…" he muttered.
The voice returned.
Closer.
Clearer.
"…This is where you break."
Muyeon smirked faintly.
"…Or where I take everything."
Silence.
Then—
The Abyss appeared.
Not chains.
Not restrained.
Its true form.
A massive shadow—
Shifting—
Endless—
Eyes everywhere.
Watching him.
Muyeon's body froze for a split second.
Not fear.
Instinct.
Danger beyond logic.
"…So this is your real form."
The entity spoke.
"…No."
A pause.
"…This is only what you can perceive."
The pressure increased.
Muyeon's knees almost bent—
Almost.
But didn't.
"…Good," the entity whispered.
"…You resist."
Muyeon exhaled slowly.
"…Enough talk."
He stepped forward.
And attacked.
BOOM—!!
His fist tore through the void—
But—
It passed through.
Nothing.
The Abyss didn't move.
"…Physical attacks…" it said quietly.
"…Are meaningless here."
Muyeon clicked his tongue.
"…Then we do it your way."
The system flickered violently.
[SYSTEM CORE EXPOSED]
[MENTAL LINK ESTABLISHED]
Pain.
Instant.
Sharp.
Muyeon's vision cracked—
Fragments of memories—
Not his—
Screams.
Failed users.
Bodies breaking.
Minds collapsing.
"…They all tried…" the voice echoed.
"…They all failed."
Muyeon clenched his head.
"…Shut up…"
The pressure increased.
Trying to crush him.
Overwrite him.
Consume him.
[WARNING: EGO COLLAPSE IMMINENT]
Muyeon's breathing slowed.
Then—
He smiled.
"…So this is it?"
The entity paused.
"…What?"
Muyeon's eyes sharpened.
"…You think I'll break like them?"
The void trembled slightly.
"…You already are."
Muyeon laughed.
Low.
Cold.
"…You're wrong."
He stepped forward again.
Even as cracks spread across his body—
Even as his mind was being torn apart—
He moved.
"…I'm not resisting you…"
The Abyss stilled.
"…What are you doing…"
Muyeon raised his hand—
And grabbed the darkness itself.
GRIP—!!
"…I'm taking you."
Silence.
Then—
The entire void shook violently.
"…Impossible."
Muyeon's system exploded with light.
[ERROR]
[ERROR]
[CONTROL CONFLICT DETECTED]
Muyeon's voice turned colder.
"…You said it yourself."
A pause.
"…I can replace you."
The Abyss surged.
Trying to overwhelm him.
Consume him completely.
But—
Muyeon didn't let go.
His grip tightened.
Even as his arm began to shatter—
CRACK—!!
"…You're not the only monster here."
The system went berserk.
[FORCED ABSORPTION INITIATED]
[STABILITY: CRITICAL]
The Abyss roared—
For the first time.
Not calm.
Not composed.
Angry.
"…YOU WILL BREAK—!!"
Muyeon's vision went white—
Black—
Then—
Nothing.
Silence.
Then—
THUMP.
One heartbeat.
But this time—
It wasn't the Abyss's.
It was his.
Muyeon opened his eyes slowly.
The void was cracking.
Breaking apart.
"…Looks like…"
He exhaled.
"…I won this round."
The Abyss's voice was faint now.
"…No…"
A pause.
"…You only survived."
Muyeon smirked.
"…Same thing."
The system stabilized slightly.
[SYSTEM EVOLUTION: PARTIAL SUCCESS]
[NEW AUTHORITY GAINED]
Muyeon's eyes glowed faintly.
Different.
Deeper.
More dangerous.
"…We're not done," the Abyss whispered.
Muyeon turned away.
"…Good."
Because neither was he.
The void collapsed completely.
And Muyeon—
Returned.
