The ground didn't stop trembling.
Even after the fight ended—
Even after the unknown commander left—
Something remained.
Unstable.
Arjun stood still.
Eyes on the map.
[Zone 17-D Status: Controlled]
But—
A new signal pulsed beneath it.
Irregular.
"…That wasn't there before," he said.
The drone reacted instantly.
[Sub-surface energy fluctuation detected]
"…Explain."
[Energy accumulation exceeding standard zone parameters]
Arjun's eyes narrowed.
"…So control triggered something."
The system pulsed.
Hard.
[WARNING]
The ground cracked.
Deep.
Not like before.
Not surface-level.
This—
Was coming from below.
The squad stepped back instinctively.
"…This isn't normal," the girl said.
"…No."
Arjun raised the rifle slightly.
"…It's reaction."
The system confirmed.
[Zone Guardian Protocol Activated]
Silence.
"…Guardian?" the older man said.
Arjun didn't respond.
Because—
The ground broke.
Completely.
A massive fracture split the street.
Dark.
Deep.
Then—
Movement.
Slow.
Heavy.
Something rose from within.
Not fast.
Not agile.
But—
Overwhelming.
[New Entity Detected]
The system identified it instantly.
Designation: Zone Guardian — G17-D
Threat Level: Extreme
The creature emerged fully.
Massive.
At least fifteen meters tall.
Its body—
Layered with dense, metallic armor.
Glowing lines pulsed beneath its surface.
Like—
Energy contained inside something too heavy to move.
"…That's not a Hunter," the injured man whispered.
"…No."
Arjun's grip tightened.
"…That's the zone itself fighting back."
The Guardian moved.
One step—
The ground collapsed beneath it.
Not from weight.
From force.
The system updated.
[Guardian Core Linked to Zone Stability]
Arjun's eyes sharpened.
"…So if it stays—"
[Zone control efficiency will decrease]
"…And if we kill it?"
[Zone stability will permanently increase]
Silence.
"…So this isn't optional," the older man said.
"…No."
Arjun stepped forward.
"…It's mandatory."
The Guardian's head turned.
Its glowing core—
Locked onto him.
Then—
It moved.
Not fast—
But direct.
Each step—
Crushing.
Unavoidable.
Arjun activated Threat Prediction.
The system flickered.
[Prediction: Partial]
"…Still not fully stable," he muttered.
The Guardian raised its arm.
Energy gathered.
Dense.
Compressed.
"…Move!" Arjun shouted.
The beam fired.
The street vanished.
Not shattered—
Erased.
The squad scattered.
Barely escaping.
"…That's elite level," the girl said.
"…No."
Arjun's voice stayed calm.
"…That's above it."
The Guardian advanced again.
Slow.
Relentless.
No hesitation.
No adaptation.
Just—
Execution.
"…It's not thinking," Arjun said.
The drone confirmed.
[Behavior Pattern: Fixed Protocol]
"…Good."
A pause.
"…Then it can be broken."
Arjun moved.
Not toward it—
Around it.
Circling.
Analyzing.
The Guardian reacted—
But delayed.
"…There's a lag," he realized.
The system updated.
[Reaction Delay: 1.6 seconds]
"…That's the opening."
He raised the rifle.
Fired.
The plasma blast hit its armor—
Minimal effect.
"…Not the surface."
The drone scanned rapidly.
[Core location detected]
A marker appeared.
Deep.
Center mass.
Heavily protected.
"…Of course."
The Guardian attacked again.
Arjun moved.
Timing it.
Using delay.
Every step—
Measured.
Every move—
Calculated.
"…We don't overpower it," he said.
"…We dismantle it."
The squad repositioned.
Following his lead.
For the first time—
They weren't reacting.
They were executing.
The Guardian roared.
The zone trembled.
And the battle—
Had just begun.
