The Dreadnought tore down the broken asphalt of the Presidente Dutra Highway at a hundred and thirty kilometers per hour. Valéria had swapped the tank treads for vulcanized rubber tires with improvised adamantium so we could gain speed on the road.
"Silas Vilela," I said, reading a coffee-stained file on my cracked tablet. "He was the director of the S?o Paulo Institute of Computing. While my father wanted to merge humans with aliens, Dr. Vilela thought flesh was obsolete. He spent the early days of the apocalypse downloading the human internet and the consciousness of a few volunteers into an armored mainframe."
"And where is this supercomputer?" Luna asked from the backseat, clutching her seatbelt as the truck bounced over the carcass of a charred bus.
"In the basement of the MASP. The S?o Paulo Museum of Art. The irony is he used Latin America's largest art vault to store memes, Wikipedia articles, and, hopefully, a cyberwarfare algorithm lethal enough to fry the Piper."
"We're reaching the state border," Gristle pointed out the turret window. "The sky looks... weird."
She was right. The tropical blue was left behind.
Ahead of us, a dome of perpetual pollution covered the horizon. It wasn't magical fog like Petrópolis. It was a swirling storm of concrete dust, asbestos, and dead nanobots. The sun barely penetrated the cloud, bathing everything in a sickly, sepia filter.
"Activate cabin filters," I ordered. The Parasite vibrated in my liver, analyzing the air composition outside.
[TOXICITY ALERT: SHARP PARTICULATE MATTER DETECTED.]
[BREATHABLE AIR CONTAINS 40% MICRO-GLASS. INHALATION WILL CAUSE PULMONARY HEMORRHAGE IN 10 MINUTES.]
"Nobody open a window," I warned. "S?o Paulo's air was always bad, but now it literally chews your lungs."
We passed the rusted sign that read "Welcome to S?o Paulo".
The city wasn't in classic ruins. The buildings hadn't fallen; they had fused. The magic of the apocalypse reacted with hyper-urbanization, creating artificial mountains of reinforced concrete. Bridges twisted like steel roots, connecting skyscrapers that looked like stalactites sprouting from the ground.
There were no plants. There was no clean water. The Tietê River, running alongside the Marginal expressway, was now a canal of fluorescent green sulfuric acid that bubbled slowly.
"A city without biomass," murmured Luna, impressed and scared. "What lives here?"
The ground shook before I could answer.
It wasn't an engine tremor. It was a rhythmic earthquake. THUMP. THUMP. THUMP.
Valéria braked hard, making the Dreadnought skid sideways, stopping inches from the acid river's low wall.
The asphalt of the Marginal Tietê burst open a hundred meters ahead of us.
A creature erupted from the earth. But it wasn't made of flesh.
It was a subway train.
Or rather, the carcass of a Yellow Line train, whose cars had fused with steel cables, rails, and static magic, forming a colossal mechanical centipede. The train car doors opened and closed like gills, and the driver's cabin was a blind "head" full of broken headlights and teeth made of sharp turnstiles.
"Subway Worm," I identified, feeling a mix of dread and professional fascination. "An urban elemental. The city came to life and is angry about the traffic."
If you spot this tale on Amazon, know that it has been stolen. Report the violation.
The Worm let out a metallic screech—the sound of train brakes amplified a thousand times—and dove back into the asphalt as if it were water, swimming under the street toward us. The ground rippled like a rug being pulled.
"It's coming from underneath!" Gristle shouted, spinning the harpoon cannon turret. "I can't aim at something in the dirt!"
"Valéria, evasive! Get off the Marginal!" I yelled.
"The access ramp is blocked by fused cars!" She threw it in reverse. "We're going to have to play matador!"
The asphalt exploded right beneath the truck's front axle.
The Worm's turnstile mouth tried to bite our engine. Valéria floored the Ether nitrous, making the truck "jump" backward. The monster's metal fangs scraped our front armor, throwing sparks.
The colossal Worm rose into the air, projecting three car lengths above us, blocking the little sunlight.
"Luna! The sonic radar! Find this thing's 'heart'!" I ordered, activating my surgical gloves.
Luna connected the baton to the dashboard and sent a pulse toward the monster's steel belly.
"Arthur, it doesn't have a heart! But the third car... is radiating extreme heat. It's the main battery!"
"Gristle! Aim for the third car!" I pointed. "Valéria, I need you to put the truck on top of it."
"On top of the giant worm that eats asphalt? Have you been drinking formaldehyde, Doctor?!" Valéria spun the wheel, dodging a headbutt from the monster that destroyed the river wall.
"It's armored on the sides, but the roof of the cars is fragile! That's where the AC exhaust vents were! Put me up there!"
Valéria didn't argue. She waited for the Worm to dive again. When the asphalt began to ripple toward us, she didn't back up. She accelerated toward the concrete "wave."
The monster emerged to strike. The Dreadnought used the Worm's head as a ramp.
We flew for a terrifying second and landed with a deafening thud on the "back" of the third car.
The monster roared and began to thrash, trying to throw us into the acid river.
The truck's rubber treads whined, trying to maintain grip on the moving car's metal roof.
"Keep it steady!" I opened the top hatch. S?o Paulo's toxic air invaded the cabin, but the Parasite was already filtering the oxygen through my closed pores.
I jumped onto the roof of the moving car. The wind, full of glass and concrete, cut my lab coat.
Beneath my feet, I felt the hum of an out-of-control power plant.
I drew my Mithril-coated scalpel.
[STRUCTURAL ANALYSIS: CARBON STEEL ALLOY. THICKNESS: 5 MILLIMETERS.]
[INITIATING MAJOR SURGICAL INCISION.]
I channeled the Parasite's purple energy into the blade and drove it into the car roof, running backward and tearing the metal like aluminum foil.
The inside of the car was exposed.
There were no seats. There was a pulsating core of high-voltage cables and dirty mana crystals, generating the anomaly that gave life to the train.
"Arthur, it's going to dive again!" Luna's voice cracked in my earpiece.
The Worm tilted its head down, preparing to dig into the concrete. If it went down, I would be crushed between the train and the asphalt.
I pulled a homemade Electromagnetic Pulse Grenade (a modified Seraph battery) from my belt.
"Last stop. Please disembark on this side," I murmured.
I threw the grenade straight into the core of exposed cables.
I ran and jumped back into the truck's hatch.
"Valéria, go, go, go!"
The Dreadnought skidded off the Worm's back the exact moment the grenade detonated.
There was no fire. There was a blue flash and a deafening ZAP.
The pulse fried the monster's electrical nervous system. The "head" headlights went out. The joints of the cars locked up.
The Subway Worm lost control of its dive and crashed face-first into the base of an overpass, folding up like a scrap iron accordion.
The dust settled. The Marginal returned to silence.
The truck stopped, smoking, a few meters from the inert creature.
Gristle opened the hatch and whistled.
"Nice reflexes, Doctor. But look up. I think we're here."
I looked through the dusty window.
We were at the beginning of Avenida Paulista.
On the horizon, suspended by its four iconic red pillars—now thick as sequoias and covered in fiber optic vines—was the MASP. The free span under the museum was sealed by lead gates.
It was the data fortress.
We drove slowly up to it, our headlights cutting through the dry fog.
There were no guards at the door. There was only a green-screen terminal and a mechanical keyboard stained with old blood.
I got out of the truck and walked to the terminal.
The screen was black. I tapped the keyboard.
A cursor blinked. Lines of code began scrolling down the screen at breakneck speed.
And then, a message appeared in perfectly formatted Portuguese:
[ACCESS REQUESTED. BIOMETRIC IDENTIFICATION DENIED.]
[...WAIT.]
[PARASITIC DNA ANALYSIS COMPLETE.]
[WELCOME, ARTHUR VERAS. YOUR FATHER SAID YOU WOULD EVENTUALLY NEED HELP.]
A hidden hydraulic door in the concrete floor opened with a hiss of decompression, revealing a staircase illuminated by blue neon lights descending into the darkness.
"The Ghost is home," I smiled, putting my scalpel away. "And it seems he's been waiting for us for twenty years. Let's go in."
