Kai couldn't breathe.
The moment that dark glow entered his chest, everything stopped.
Not slowed.
Stopped.
Sound vanished.
The wind disappeared.
Even the pain in his body faded into nothing.
For a second, it felt like he no longer existed.
Then—
It hit.
His body jerked violently as a crushing force exploded inside him. Not outside. Not around him.
Inside.
Like something had just been forced into a space too small to contain it.
"Ghh—!"
He dropped forward, both hands hitting the ground as his vision distorted. The world bent unnaturally, twisting at the edges like reality itself couldn't hold steady.
"…Get out…"
The words came out weak.
Useless.
Whatever entered him didn't listen.
It spread.
Slowly at first.
Then faster.
Cold.
Not freezing.
But empty.
Like something that didn't belong to warmth, life, or anything human.
Kai's chest tightened.
His heartbeat became irregular.
Too fast.
Too slow.
Then both at once.
The system flickered violently.
[Warning]
[Foreign Energy Assimilation in progress]
[Host compatibility unknown]
Kai's fingers dug into the ground.
"…unknown…?"
His voice shook this time.
Not from fear.
From the pressure.
It kept building.
Layer after layer.
Something inside him was changing.
Not evolving.
Changing.
And that difference felt dangerous.
Very dangerous.
His vision snapped upward.
For a moment, he wasn't seeing the real world anymore.
Darkness stretched endlessly in every direction.
Not empty.
Watching.
Something moved within it.
Massive.
Silent.
Alive.
Kai's breath caught in his throat.
"…what is that…"
It didn't answer.
It didn't need to.
Because the moment he noticed it—
It noticed him.
A presence pressed down on him.
Not physical.
But absolute.
Like the weight of something that existed far beyond what he could understand.
Kai's body trembled.
Not from weakness.
From instinct.
Run.
Hide.
Disappear.
Anything but stay here.
But he couldn't move.
Something held him in place.
Forced him to look.
The shape in the darkness shifted.
Closer now.
Still unclear.
Still impossible to fully see.
But its eyes—
He saw those.
Not glowing.
Not burning.
Just there.
Endless.
Ancient.
Hungry.
Kai's heart skipped.
"…you're inside me…"
The realization came too fast.
Too sharp.
And the moment it did—
The world snapped back.
Kai gasped.
Air rushed into his lungs violently as his body collapsed fully onto the ground.
The sky returned.
The broken battlefield.
The corpse behind him.
Everything was back.
But nothing felt the same.
"…what… was that…"
His voice was barely a whisper now.
His body felt heavy.
But also…
Stronger.
Not in a simple way.
Not like before.
This felt deeper.
Unstable.
Like power that didn't fully belong to him.
The system reappeared.
Glitching.
Flickering.
Struggling to stabilize.
[Assimilation Complete]
[New Trait Acquired]
[???]
Kai stared at it.
"…You're not even telling me?"
No response.
The question marks remained.
Unchanged.
A cold feeling settled in his chest.
"…So even you don't understand it."
That was worse.
Much worse.
Kai pushed himself up slowly.
His body protested.
Every muscle ached.
Every wound burned.
But beneath it all—
There was something else.
A quiet hum.
Constant.
Alive.
He placed a hand over his chest.
Right where the dark energy had entered.
"…You're still there."
It wasn't a guess.
It was certainty.
Something had taken root inside him.
Something that wasn't part of the system.
Something older.
His eyes lifted.
And for a split second—
The world flickered again.
Not fully.
Just enough.
The ground beneath him looked the same.
But also not.
Cracks spread across it.
Dark ones.
Moving ones.
Like something beneath the surface was trying to break through.
Kai blinked.
It disappeared.
"…Great."
Now he was seeing things.
Or worse—
Seeing something real.
[Notice]
[Host has entered a new evolutionary path]
Kai froze.
"…New path?"
That hadn't shown before.
Not once.
His fingers tightened slightly.
"…What kind of path…"
The system didn't answer.
But he already had a feeling.
It wasn't a normal one.
It couldn't be.
Not after what he just saw.
Not after what he just felt.
Kai exhaled slowly.
Trying to steady himself.
Trying to think clearly.
That was when he heard it.
Footsteps.
Far away.
But approaching.
Fast.
More than one person this time.
Voices followed.
Sharp.
Alert.
"…Energy spike detected here!"
"Be careful, something's wrong with this gate!"
"Wait—there's someone there!"
Kai's head turned.
Figures appeared in the distance.
Not the same hunters from before.
Different.
Better equipped.
Stronger.
Their presence alone felt heavier.
More controlled.
A guild team.
And they were coming straight toward him.
Kai stood still.
Watching.
Waiting.
Something inside him stirred.
That same cold presence from before.
Quiet.
But awake.
The closer the hunters got—
The stronger it reacted.
Like it recognized something.
Or someone.
Kai's eyes narrowed slightly.
"…Don't start now."
But it didn't listen.
It pulsed.
Once.
Then again.
The air around him shifted.
Subtly.
But enough.
The leading hunter suddenly stopped.
His expression changed instantly.
From focused…
To alarmed.
"…Hold on."
The others froze.
"What is it?"
The man's eyes locked onto Kai.
Sharp.
Suspicious.
"…Something's wrong with him."
Kai didn't move.
Didn't speak.
But inside—
Something smiled.
Not him.
Something else.
"…Yeah," Kai whispered under his breath.
"…I think you're right."
