The ventilation shaft was a coffin of rust and darkness.
Maya crawled first, elbows scraping against jagged metal, knees burning on the rough surface.
The laptop bag dragged behind her like a dead weight, its strap cutting into her shoulder.
Every breath tasted like dust and old iron.
Leo followed close, his saxophone case bumping against the walls with every movement.
His breathing was steady—calm, controlled, as if he had done this a hundred times before.
Behind them—muffled explosions.
The bunker door had finally given way.
Shouts echoed through the shaft, distorted and distant.
"Fan out! They're in the vents!"
Maya's heart slammed against her ribs.
She could feel the agents' boots vibrating through the metal.
"Faster," Leo whispered. "They'll use thermal scans. We're sitting ducks if we stop."
Maya pushed harder.
The shaft sloped downward—steeper now.
Her palms bled from gripping the rough edges.
Suddenly—the shaft ended.
A rusted grate blocked the way forward.
Maya shoved against it.
It didn't budge.
Leo crawled up beside her.
"Hold on."
He pulled a small multi-tool from his jacket, wedged it into the grate's edge, and twisted.
Metal groaned.
The grate popped free.
They tumbled out into a wide, echoing sewer tunnel.
Water rushed ankle-deep—cold, filthy, smelling of decay.
Maya landed hard, gasping.
Leo helped her up.
"This way," he said, pointing left. "Three blocks to the surface. Old maintenance ladder."
They ran.
The tunnel was massive—vaulted ceiling lost in shadow, walls dripping with slime.
The water rushed past their legs, threatening to pull them under.
Maya's laptop bag was soaked.
Her mind raced.
The virus was spreading.
The Aegis was offline.
The city was free.
But they weren't.
A low hum filled the tunnel.
Maya froze.
Leo stopped too.
The hum grew louder—mechanical, rhythmic.
A drone.
Not Aegis—something older, smaller, pre-algorithm tech.
It rounded the corner ahead—silver, sleek, red lens glowing.
It hovered.
Scanned.
Locked on them.
Maya's voice was a whisper.
"They adapted. The system learned from the EMP."
Leo's eyes narrowed.
"Then we adapt faster."
He raised the saxophone case.
Opened it.
Pulled out a small black cylinder—another jammer.
He clicked it on.
The drone stuttered—lens flickering.
But it didn't fall.
It advanced.
Leo cursed.
"It's shielded."
Maya's eyes darted to the walls.
Old pipes.
Rusted valves.
She ran to one.
Turned it hard.
Water exploded from the pipe—high-pressure, freezing.
The drone was caught in the blast.
It spun, sensors overloaded.
It crashed into the wall.
Sparks.
Silence.
Maya turned to Leo.
"We're not done."
Leo nodded.
"We're just starting."
They ran again.
The ladder was ahead—rusted, but solid.
Maya climbed first.
Leo followed.
Halfway up—the tunnel behind them lit up.
Flashlights.
Shouts.
"They're in the sewer! Seal the exits!"
Maya reached the top.
Pushed the manhole cover.
It moved.
She shoved it aside.
Rain poured in.
Fresh air.
The city street above—chaos.
Lights flickering.
Cars stalled.
People screaming as the algorithm collapsed.
Maya climbed out.
Leo followed.
They stood in the rain.
The city was waking up.
But so was the Aegis.
In the distance—sirens.
A low hum.
Drones.
Leo looked at Maya.
"We broke the cage."
Maya looked back at him.
"Now we burn it down."
