The sound of the rushing water changed instantly.
It stopped hitting the wet concrete walkway with the crisp, clean roar of high pressure. It hit with a thick, sickening, wet slop. The crisp, cold smell of the subterranean lake was violently replaced by a suffocating, chemical stench that smelled like rotting vegetation and heavy ozone.
Marcus sprinted past the shattered Burner clones and the severed hand. He grabbed his bleeding left arm tightly against his chest.
He reached the edge of the narrow concrete walkway and looked down into the massive cavern.
The fifty-foot drop to the subterranean lake was terrifyingly dark.
The perfectly clear, pristine drinking water of the Naples reservoir—the massive body of water Lucilla had just opened the valves to—was rapidly shifting.
It wasn't a slow discoloration. It was a violent chemical reaction.
Massive, swirling clouds of thick, toxic black ink were violently blooming beneath the surface. They spread with unnatural, aggressive speed, instantly swallowing the faint, eerie blue light cast by the broken Amp resting on the bottom of the lake.
The water was boiling without heat. Thick, dark bubbles violently broke the surface, releasing noxious gas into the enclosed cavern.
The Warlord's Warlord math clicked instantly in Marcus's mind.
It was a cold, horrifying realization.
Nero didn't just rig the acid bomb to fall from the ceiling. That was a theatrical distraction.
While Marcus was fighting the Burner Mech on the beach, while he was hanging upside down cutting wires, Nero had already introduced a slow-acting, highly concentrated terraforming defoliant directly into the main reservoir.
Nero didn't just want to blow the water up. He wanted to poison the well.
And Lucilla had just opened the main digital valves.
"Lucilla!" Marcus roared over the sickening sound of the black sludge hitting the concrete. His voice was frantic, the iron Warlord momentarily replaced by sheer panic for his people.
Lucilla scrambled up from the wet concrete, clutching her datapad. She stared at the swirling black lake in absolute horror.
"The valves are open," Lucilla stammered, her hands shaking violently. "Marcus, the pipes are running at maximum capacity! They're pumping millions of gallons straight into the ocean aqueduct!"
"Shut them down!" Marcus ordered, pointing at the massive glass terminal. "Right now!"
If that thick, toxic black water hit the Carrier's main intake valves miles offshore, it wouldn't just kill the five thousand scavengers. It would permanently contaminate the ship's entire internal plumbing system. The Carrier would become a floating coffin of poison.
The Warlord's thirty-six-hour clock hadn't been stopped.
It had been weaponized into a two-minute countdown.
Lucilla slammed the connection cable back into the main terminal. She didn't hesitate. She didn't cry. The Butcher was fully awake.
Her fingers flew across the datapad, her eyes scanning the rapidly cascading lines of green Board code on the massive screen.
"I'm initiating an emergency override sequence," Lucilla yelled over her shoulder, her voice tight with concentration. "I'm trying to force the primary intake valves to close!"
She hit the final execute command.
The massive terminal screen instantly flashed from bright green to a harsh, blinding red.
[OVERRIDE DENIED. SYSTEM LOCKED. ENCRYPTION PROTOCOL: VANE-OMEGA OMEGA. EXTERNAL ACCESS TERMINATED.]
A loud, mocking electronic buzzer echoed through the cavern.
"He locked it!" Lucilla screamed in despair, dropping the datapad. "Nero locked the entire grid from the inside of the elevator shaft before he confronted us! The digital bypass is completely dead!"
She spun around to face Marcus. Her pale face was desperate.
"Marcus, I can't hack it. The system isn't rejecting my code. The system is physically disconnected from this terminal. It's a hardline lockout."
Marcia ran to the edge of the walkway. She looked down at the boiling, black defoliant rapidly filling the massive cavern. The smell was physically burning her eyes, making her cough violently.
"Two minutes," Marcia choked out, covering her mouth with her torn coat sleeve. "If the water pressure is maximum, the poison hits the Carrier in less than two minutes."
Marcus stared at the red terminal screen.
He didn't have JARVIS to brute-force the hardware. He didn't have Galen to rewire the console.
He looked at his massive brother.
"Narcissus," Marcus commanded, turning to the Iron Dog.
The giant stood perfectly still, his heavily dented battleship steel armor still hissing faintly.
"Can you rip the terminal out?" Marcus asked. "Can you physically destroy the console and force a hard reset?"
Lucilla shook her head violently. "No! If he destroys the terminal, the default Board protocol is to leave the valves in their current state to prevent pressure buildup! If he smashes it, the valves stay open forever!"
The Warlord's Warlord math offered no digital solution.
Marcus looked back down into the massive, toxic lake.
Fifty feet down, directly beneath the metal grating where the collapsed catwalk used to be, he saw it.
It was barely visible through the swirling black ink.
A massive, rusted, ten-foot-wide manual shut-off wheel was bolted directly to the primary intake pipe on the concrete floor of the reservoir.
It was the analog fail-safe. The physical override Executive Vane had built in case the terraforming grid lost power.
"The physical valve," Marcus pointed straight down into the black water. "It's submerged. Ten feet below the surface."
Narcissus immediately stepped forward.
The massive iron giant reached the edge of the concrete walkway, his hydraulic legs whining. He looked down into the boiling black liquid. He prepared to drop his two-ton weight into the abyss to turn the wheel.
"Stop!" Marcus grabbed the thick, cherry-red steel of Narcissus's arm.
He looked at the deep, ragged gouges in the giant's armor where the Burner clones had focused their flamethrowers. The thick metal was warped. The hydraulic fluid lines were exposed and leaking slightly.
"Your armor is compromised," Marcus said, his voice flat. "The seals are broken. If you submerge in that chemical defoliant, it will instantly eat through your exposed wiring. You'll short-circuit. You'll sink, and you'll never come back up."
Narcissus looked at the Warlord. His red optical sensors pulsed slowly in the dark.
"I am Warlord iron," Narcissus rumbled softly. "I hold."
"You hold the line up here," Marcus ordered, his Warlord iron absolute. "I'm not drowning you today."
Marcus realized the manual shut-off valve couldn't be turned by a machine. It had to be flesh and blood.
He was bleeding heavily from the deep cut on his left bicep. His muscles were exhausted from fighting the Burners. He had nearly drowned ten minutes ago.
But he was Warlord Commodus.
He reached over his shoulder and unlatched the heavy leather scabbard. He drew the polished Warlord sword.
He didn't throw it. He handed it to Marcia.
"Hold this," Marcus commanded.
Marcia took the heavy steel blade. Her scarred face was tight with absolute terror. She knew exactly what he was about to do.
"Marcus, you're bleeding," she said, her voice cracking. "That water is concentrated chemical acid. It will burn you alive."
"It's going to burn five thousand people if I don't," Marcus said coldly.
He didn't wait for her to argue. He didn't give her a chance to offer to go in his place.
He didn't look at Lucilla. He didn't look at Narcissus.
Marcus took three rapid, heavy steps backward on the wet concrete.
He took a massive, deep breath of the foul, ozone-choked air, filling his lungs to maximum capacity.
He sprinted forward.
He vaulted entirely over the narrow concrete railing.
He dove headfirst off the fifty-foot ledge, directly into the boiling, toxic black defoliant.
The impact was brutal.
The black water didn't just feel cold. It felt like liquid fire.
The highly concentrated terraforming chemicals instantly attacked his skin. The pain was immediate, agonizing, and absolute. It felt like millions of tiny needles driving directly into his pores.
The deep cut on his left bicep screamed in protest as the toxic sludge flooded the open wound, searing the muscle tissue.
Marcus squeezed his eyes tightly shut, but the chemicals still burned through his eyelids.
He was completely, terrifyingly blind.
He didn't panic. He let the momentum of his dive carry him downward. He kicked his heavy, melted combat boots violently, swimming straight into the dark abyss.
He swept his arms out in front of him, feeling the thick, sludgy resistance of the poisoned water.
Five feet. Seven feet. Ten feet.
His burned left hand slammed hard against solid, rusted iron.
He had found the wheel.
Marcus grabbed the thick, ten-foot-wide manual shut-off valve with both hands. He braced his boots against the slick concrete wall of the massive intake pipe.
He pulled.
He poured every ounce of his analog, Warlord strength into his arms. His muscles screamed. His lungs burned with the desperate need for air. The chemicals ate at his skin.
The massive iron wheel groaned in the dark.
It was rusted shut. It hadn't been moved in years. He was fighting the sheer water pressure of millions of gallons of moving liquid.
Marcus gritted his teeth, ignoring the blinding pain in his arm. He tapped his Neural Link, flooding his right arm with raw nanite energy, augmenting his physical strength.
He pulled again. Harder.
The rusted iron shrieked.
The massive wheel moved two inches.
Marcus didn't stop. He hauled the heavy iron downward, hand over hand, his boots slipping on the slick concrete. He turned it a quarter rotation. A half rotation.
The deafening rush of the water above him suddenly began to slow. The massive physical valves inside the pipe were slowly grinding shut, cutting off the flow of poison to the Carrier.
He was doing it. He was saving them.
Suddenly, the water beneath Marcus's boots shifted.
It wasn't the current of the intake pipe. It wasn't the violent boiling of the chemical reaction.
It was a massive, deliberate displacement of water.
Something immense was moving in the pitch-black depths of the lake directly beneath him.
Marcus felt the thick, sludgy water forcefully push upward against his legs.
He opened his burning eyes in the dark. He couldn't see anything in the toxic ink.
But he felt it.
A massive, heavy, leathery shape brushed hard against his left leg. It was easily the size of a small submarine. It was cold, incredibly fast, and moving with terrifying, predatory intent.
Nero hadn't just poisoned the water.
He had terraformed the life inside it.
