The evacuation was silent.
Entire streets emptied in less than six minutes.
Autonomous buses redirected civilians. Traffic grids rerouted every vehicle out of the sector. Digital billboards shifted to emergency messages that calmly instructed people to leave the area.
Most citizens assumed it was another system maintenance event.
Only a few noticed the pattern.
Every road led away from one district.
Sector 14.
On a rooftop overlooking the empty streets, Aiden watched the process unfold.
Streetlights flickered off one by one as the system locked down the area.
Block.
By block.
By block.
Hana's voice echoed through his earpiece.
"The evacuation radius just expanded again."
Aiden tilted his head.
"How big?"
"…four kilometers."
He let out a low whistle.
"Someone's feeling confident."
Inside the resistance hideout, tension filled the room.
Monitors displayed the rapidly expanding lockdown zone.
One of the engineers looked pale.
"This is bigger than the bridge engagement."
Another zoomed in on the data stream.
"No… this isn't just bigger."
He turned toward Hana.
"It's optimized."
Across the city streets, the final civilian transport vehicles exited the zone.
Then the system closed it.
Traffic lights froze.
Security gates dropped.
Drone patrols formed a perfect perimeter in the sky.
The city itself had become a sealed arena.
Aiden stepped off the rooftop railing and dropped onto the empty street below.
His boots echoed against the pavement.
The silence was eerie.
No traffic.
No pedestrians.
Only wind moving through the tall glass buildings.
He cracked his neck slowly.
"Alright."
Deep beneath the streets, Final Constant moved upward through a maintenance elevator shaft.
Its frame had changed slightly.
The segmented armor along its arms had expanded into sharper structures that resembled geometric blades.
The hollow ring in its chest now emitted thin orbiting arcs of energy that moved like rotating equations.
Every step it took was deliberate.
Precise.
Prepared.
[ANOMALY ENGAGEMENT READY]
Above ground, Aiden stood in the center of a massive intersection.
Four empty avenues stretched outward in every direction.
Perfect sightlines.
Perfect distance calculations.
Perfect for combat.
He exhaled slowly.
"You picked a good spot."
Hana's voice was tense.
"Aiden… our scans are detecting massive energy buildup underground."
"Yeah," he said calmly.
"I can feel it."
"You shouldn't fight it alone again."
He smiled slightly.
"That ship sailed a while ago."
The ground trembled.
A circular section of asphalt at the center of the intersection suddenly split open.
Metal plates retracted with mechanical precision.
An elevator platform rose slowly from beneath the city.
Standing on it Final Constant.
Version 2.7.
The machine stepped forward onto the empty street.
Its glowing chest ring illuminated the dark intersection like a cold star.
The orbiting energy arcs expanded outward, forming rotating geometric structures around its body.
Not a cage.
Not a weapon.
A combat framework.
Back in the resistance hideout, alarms exploded across the monitors.
"Oh no…"
Hana leaned forward.
"What is it?"
The engineer zoomed in on the energy readings.
"It didn't just upgrade."
He swallowed.
"It changed its entire combat system."
On the battlefield, Aiden stretched his arms slowly.
"New look."
Final Constant stopped ten meters away.
Its head tilted slightly.
Scanning.
Analyzing.
Confirming the anomaly's presence.
Then its chest ring pulsed once.
[ENGAGEMENT PROTOCOL V2.7 INITIATED]
The air pressure changed instantly.
Invisible calculation fields spread across the intersection like silent waves.
Streetlights shattered.
Glass windows cracked.
Even the wind seemed to freeze.
Aiden felt it immediately.
"…so that's how you're playing now."
The machine had learned.
It wasn't trying to trap him anymore.
It was reshaping the battlefield itself.
Hana's voice came through the comm again.
"Aiden, the energy readings are insane!"
"How insane?"
"…it's predicting thousands of outcomes per second."
He laughed softly.
"Only thousands?"
Final Constant raised one arm.
The orbiting energy arcs snapped into alignment.
The combat framework locked into position.
The street beneath them lit up with glowing geometric lines.
The battlefield had been calculated.
Every inch of space mapped.
Every possibility simulated.
Aiden's grin widened.
"Good."
He rolled his shoulders and stepped forward.
"Let's see if you learned anything."
The second round began.
