INFINITE GROWTH SYSTEM: FROM NOTHING TO ABSOLUTE POWER

The darkness inside the building was heavier than it should have been.

Not just dark.

Alive.

Ethan stood just past the entrance, his breathing slow, controlled. The moment he stepped in, the system had flickered—then partially gone silent.

That alone told him everything.

"...This place isn’t normal."

The air felt thick, like something was pressing against his skin.

Watching.

Waiting.

A faint sound echoed deeper inside.

Footsteps.

Slow.

Measured.

Not like the mindless entities before.

This one was different.

Ethan tightened his grip on the metal pipe, but he didn’t move forward immediately.

Instead, he listened.

Rain tapped faintly against broken windows somewhere above, but inside... everything else was quiet.

Too quiet.

Then—

"You came in anyway."

The voice echoed again.

Calm.

Amused.

Ethan’s eyes narrowed.

"...Show yourself."

A low chuckle followed.

"You system users are always the same."

System users.

Plural.

Ethan’s heartbeat slowed.

"...So I’m not the only one."

The darkness ahead shifted.

A figure stepped into view.

Human.

At least... mostly.

A young man, maybe early twenties, wearing a dark jacket. His posture was relaxed, almost casual—but his eyes...

They weren’t normal.

They glowed faintly.

Like something was layered behind them.

Ethan didn’t lower his guard.

"...You’re human."

The man smiled slightly.

"That depends on your definition."

The system flickered violently in Ethan’s vision.

WARNING: HOSTILE HUMAN ENTITY DETECTED

THREAT LEVEL: HIGH

Ethan exhaled slowly.

"...So you’re not friendly."

The man tilted his head.

"Friendly? No."

He took a step forward.

"But useful?"

Ethan didn’t respond.

The man’s smile widened slightly.

"You’re new. I can tell."

His gaze scanned Ethan briefly.

"Weak stats. No skills. Barely awakened."

Ethan’s grip tightened.

"...You can see that?"

The man tapped his temple.

"Different system. Same rules."

Ethan’s eyes narrowed further.

"...System user."

The man nodded slowly.

"Exactly."

Silence stretched between them.

Then—

"Here’s how this works," the man continued. "You either walk away... and stay weak."

Another step closer.

"Or you fight me... and maybe learn something."

Ethan didn’t hesitate.

"...I’m not walking away."

The man’s smile sharpened.

"Good."

He vanished.

Ethan’s eyes widened—

Too fast.

A punch came from the side.

Ethan reacted instinctively.

He blocked—but the impact sent him sliding back across the floor.

Pain shot through his arm.

"Damn—!"

He barely regained balance before the man attacked again.

Faster.

Stronger.

Ethan dodged, but just barely.

"...He’s different."

Not like the entities.

Not predictable.

Not slow.

This was a real opponent.

The system flickered again.

COMBAT ANALYSIS INITIATED

Ethan’s vision sharpened.

The man’s movements slowed—just slightly.

Enough.

Ethan moved.

He swung the pipe.

The man blocked easily.

Metal clashed against his arm—but it didn’t even leave a mark.

"Too slow."

A kick followed instantly.

Ethan couldn’t fully dodge.

It hit his side—

He was thrown back hard, crashing into the wall.

Pain exploded through his ribs.

Ethan gritted his teeth.

"...He’s way stronger than me."

The man walked toward him slowly.

"You’re relying on instinct."

Another step.

"That won’t be enough."

Ethan pushed himself up.

Breathing heavier now.

"...Then I’ll adapt."

The system flickered violently.

SYSTEM RESPONSE: ADAPTIVE GROWTH TRIGGERED

Something inside him shifted again.

Not power.

Not yet.

Understanding.

The man moved again.

This time—

Ethan saw it.

Not clearly.

But enough.

He stepped aside just in time.

The attack missed.

The man’s eyes sharpened slightly.

"Oh?"

Ethan didn’t stop.

He moved forward instead.

Fast.

Faster than before.

The pipe swung again—

This time aiming not for strength...

But timing.

CLANG!

The hit connected.

The man stepped back slightly.

Not injured.

But surprised.

Ethan exhaled.

"...Got you."

The man smiled again.

But this time...

It wasn’t amused.

It was interested.

"Good."

He straightened slightly.

"Now it’s getting fun."

The pressure in the room increased instantly.

Ethan felt it.

This wasn’t the same level anymore.

"...He’s holding back."

The realization hit hard.

The system flashed again.

WARNING: ENEMY LIMITER REMOVED

Ethan’s heartbeat spiked.

"...Of course it is."

The man disappeared again.

This time—

Ethan barely reacted.

The hit landed.

Hard.

His body slammed into the ground.

Air knocked out of his lungs.

He coughed.

Pain everywhere.

"...Can’t... keep up..."

The man stood over him.

Looking down calmly.

"This is the difference."

He crouched slightly.

"Between someone who survives... and someone who grows."

Ethan’s fingers tightened.

"...I’m not done."

The system flickered violently.

CRITICAL CONDITION DETECTED

EMERGENCY GROWTH OPTION AVAILABLE

Ethan’s vision blurred slightly.

"...Option?"

A single prompt appeared.

ACCEPT FORCED GROWTH?

[YES] [NO]

Ethan didn’t hesitate.

"...YES."

The world snapped.

Pain surged through his entire body.

Like something inside him was being torn apart—

Then rebuilt.

Stronger.

Faster.

Sharper.

Ethan’s eyes snapped open.

Everything felt different.

Clearer.

The man stepped back slightly.

For the first time—

Surprised.

"...Now that’s interesting."

Ethan stood slowly.

Breathing steady again.

"...Let’s try this again."

He moved.

Fast.

This time—

The man’s attack came.

Ethan dodged cleanly.

No struggle.

No panic.

Just movement.

He countered instantly.

CRACK!

The hit landed solid.

The man was pushed back.

Ethan didn’t stop.

Another step.

Another strike.

Faster.

Cleaner.

Controlled.

The man blocked—but not easily anymore.

Their movements clashed repeatedly.

Back and forth.

For the first time—

It was a fight.

Not a one-sided beating.

Ethan’s breathing stayed controlled.

His eyes locked on his opponent.

"...I can keep up now."

The man smiled slowly.

"Yes..."

He stepped back.

"You’re finally starting to grow."

Silence fell briefly.

Then—

He turned away.

Ethan frowned.

"...What?"

The man walked toward the darkness.

"You’ve passed."

Ethan’s grip tightened.

"Passed what?"

The man didn’t stop.

"Your first real test."

He glanced back slightly.

"Survive longer."

Then he disappeared into the shadows.

Gone.

Just like that.

Ethan stood there.

Confused.

Breathing steady.

"...What the hell was that?"

The system returned fully.

QUEST COMPLETED: EXPLORATION

REWARD: SKILL UNLOCKED

Ethan’s vision flickered.

A new line appeared.

SKILL ACQUIRED: BASIC COMBAT INSTINCT (LEVEL 1)

Ethan exhaled slowly.

"...So that was a test."

He looked toward the darkness.

The man was gone.

But the feeling remained.

This world...

Was much bigger than he thought.

And far more dangerous.

Ethan tightened his fist.

"...Good."

A faint smile appeared.

"...Then I’ll grow stronger."
