The deeper they went—
The less the forest felt like a forest.
The trees grew taller.
Thicker.
Twisted.
Their branches blocked out what little light remained, leaving only faint streaks of gray filtering through the canopy.
The ground beneath their feet changed too.
No longer soft soil—
But dark, hardened earth.
Almost like stone.
"…This isn't normal," Kael said quietly.
The girl walking ahead didn't stop.
"…Of course it isn't."
Her voice was calm.
Unbothered.
"This is where the forest begins to reject the outside world."
Kael frowned.
"…Reject?"
She stepped over a jagged root.
"…You'll understand soon."
Silence followed.
But it wasn't empty.
It was filled with something else.
Pressure.
Not overwhelming—
But constant.
Like the deeper they walked…
The more the world itself pressed down on them.
Kael adjusted his breathing.
"…My body feels heavier."
"Good."
He blinked.
"…Good?"
She glanced back slightly.
"…It means you're still adapting."
Kael didn't respond.
But his eyes sharpened.
Everything here was different.
The energy.
The air.
Even the flow he saw with Core Sense—
"…It's denser…"
Thicker.
More violent.
Almost like it was alive.
[Core Sense Activated]
The world shifted.
And what he saw—
Made him pause.
The energy in this place wasn't flowing normally.
It twisted.
Spiraled.
Gathering toward a single direction.
"…There's something ahead."
A source.
A center.
The girl smiled faintly.
"…Now you see it."
Kael's gaze hardened.
"…What is it?"
She didn't answer immediately.
Instead—
She stopped.
Kael nearly walked into her.
"…What—"
"Don't move."
Her voice dropped.
Low.
Serious.
Kael froze instantly.
The atmosphere changed.
Subtly—
But unmistakably.
Something was there.
Watching.
Slowly—
Kael activated Core Sense again.
Ignoring the faint pain in his chest.
And then—
He saw it.
A presence.
Not one.
Not two.
Dozens.
Hidden.
Buried beneath the ground.
Within the trees.
In the shadows.
"…What the hell…"
The girl spoke quietly.
"…Don't react."
Too late.
The moment Kael focused on them—
They moved.
The ground cracked.
BOOM!
Dark shapes burst out from below.
Fast.
Violent.
Kael jumped back—
Just as something tore through where he stood.
A creature landed.
Lean.
Humanoid—
But wrong.
Its limbs were too long.
Its skin pale and cracked.
Its mouth stretched unnaturally wide.
"…What are these things?"
More appeared.
One.
Two.
Ten.
Surrounding them.
The girl sighed.
"…Scavengers."
Kael tightened his grip.
"…They don't look weak."
"They're not."
She stepped forward slightly.
"…And they don't fight alone."
As if responding to her words—
More began to emerge.
From everywhere.
Kael's eyes narrowed.
"…We're surrounded."
"…Yes."
Her tone remained calm.
Almost bored.
"…Then why did you bring me here?"
She glanced at him.
A faint smile forming.
"…Because this is where you grow."
Before Kael could respond—
The creatures attacked.
They moved as one.
A wave of distorted bodies rushing forward.
Kael reacted instantly.
Step.
Slash.
The first one fell.
But—
It didn't stop.
Even with its chest split open—
It kept moving.
"…What—?!"
"They don't feel pain," the girl said calmly.
Another lunged—
Kael twisted—
Cutting its head clean off.
This time—
It dropped.
"…Head or core…"
He adjusted instantly.
The swarm closed in.
Kael moved.
Faster.
Sharper.
But there were too many.
One grazed his arm.
Another clawed his side.
"…Tch!"
His movements slowed.
[Warning: Host fatigue increasing]
"…Damn it…"
Then—
The girl moved.
Kael didn't even see it clearly.
One moment she was standing still—
The next—
She was in the middle of the swarm.
And then—
Everything died.
Silence.
Kael froze.
The creatures—
All of them—
Collapsed.
Clean cuts.
Precise.
Instant.
"…What…"
She stood there calmly.
Not even breathing heavily.
"…Too slow," she said, glancing at him.
Kael stared.
"…You could've done that from the start."
"…Yes."
"…Then why didn't you?"
She turned slightly.
"…Because you need to learn."
Kael's jaw tightened.
"…I'm not your student."
"…No," she agreed.
"…You're something more troublesome."
A pause.
"…And more fragile."
Kael didn't respond.
Because she wasn't wrong.
He looked around.
Dozens of corpses.
"…If there are this many here…"
"They're guarding something."
Kael's eyes sharpened.
"…The source."
She nodded slightly.
"…Come."
This time—
She didn't wait.
Kael followed.
The path ahead grew narrower.
The trees closing in.
The darkness deepening.
Until—
They reached it.
An opening.
A massive crater.
At its center—
Something pulsed.
Kael stepped closer.
Slowly.
"…What is that…"
At the bottom of the crater—
A massive core.
Not like the ones he had seen before.
This one—
Was alive.
It beat.
Like a heart.
Each pulse sent waves of energy through the area.
Feeding everything.
Corrupting everything.
Kael's breath caught.
"…This is…"
"The source."
The girl stepped beside him.
"…This is what creates everything you've been fighting."
Kael's eyes darkened.
"…Then I destroy it."
He stepped forward—
But—
A hand stopped him.
"…Don't."
Kael frowned.
"…Why?"
Her gaze remained fixed on the core.
"…Because you can't."
Silence.
"…Not yet."
Kael's grip tightened.
"…Then why bring me here?"
She looked at him.
"…To show you the truth."
A pause.
"…Power isn't just something you gain."
Her eyes flickered slightly.
"…It's something you survive."
The core pulsed again.
Stronger this time.
And then—
Something changed.
The ground trembled.
Kael's eyes widened.
"…What now…?"
The girl's expression shifted.
For the first time—
Serious.
"…We're too late."
From the core—
Something began to rise.
Slowly.
A shape.
Large.
Monstrous.
Kael's grip tightened.
"…That's not normal…"
"…No," she said quietly.
"…It's not."
The creature emerged fully.
Towering.
Twisted.
Its body formed from the very energy of the core.
And its eyes—
Locked onto them.
Kael's instincts screamed.
Run.
But he didn't move.
Instead—
He smiled.
"…Good."
The girl glanced at him.
"…You're insane."
"…Maybe."
Kael stepped forward.
"…But I need this."
The creature roared.
And the battle began.
