[Campus Building B3 Basement, Collapse Day Unknown, Midday]
The basement was loud.
Not normal loud. Weapon loud.
The heads on the tree branches were screaming, dozens of voices layered over each other until the sound was a physical thing that pressed against the chest and settled behind the eyes.
Men. Women. A child.
"Help me! It hurts! Please!"
Chloe's hands flew to her ears. Her knees hit concrete hard.
"Make it stop!" She pressed her palms flat. "They're alive!"
Ren didn't cover his ears.
He gripped the fire axe.
"They're not alive," he shouted over the wall of noise. "They're fruit. Don't listen to them."
'Fruit,' he reminded himself. 'Just fruit. Weird murder fruit.'
A root punched up through the concrete. Thick as a man's thigh, moving with the kind of confidence that came from knowing exactly where it was aimed.
Ren's chest.
He side-stepped.
[Dash.]
He swung.
Thwack.
The blade buried deep. Green sap sprayed in a wide arc and hissed wherever it touched the floor, eating into the concrete like something hungry.
The tree screamed again. All the heads opened wider, jaws unhinged to a degree that made no anatomical sense.
"Intruder! Meat! Eat him!"
Three more roots burst from the ground, moving like whips, cracking through the air.
One got his ankle.
It pulled. Hard. No warning.
Ren went down. The axe clattered out of his grip and skidded six feet away across the wet floor.
The root dragged him. Concrete scraped against his back as the trunk loomed closer, the bark peeling open to reveal a toothless, gaping maw dripping green slime. The smell hit him first: rotting flowers and copper, hot and wet and deeply, specifically wrong.
'So that's what a tree's mouth smells like. Horrifying.'
"Ren!" Chloe yelled.
He kicked the root with his free foot. It didn't care. The grip was mechanical, indifferent, like being held by something that had never once considered the concept of letting go.
His fingernails scraped concrete. Two broke.
Five feet from the trunk now.
"Chloe!" he roared. "The chemicals! Throw them!"
Chloe wasn't moving. She was staring at one of the faces. It looked exactly like her math teacher, mouth wide open, screaming. 'That's Mr. Harfield's voice. His voice. I watched him die in the gym why is he in the tree why is he—'
"Throw it!"
She snapped.
She grabbed the bottle from her bag without aiming, without thinking, and hurled it at the trunk as hard as she could.
It hit just above the open mouth and shattered.
Hisssss.
Acid burned dark across the bark and across the screaming faces near the impact zone. The tree shrieked at a pitch that made the remaining chemical bottles in Chloe's bag vibrate.
The roots went loose for one second.
That was enough.
Ren rolled. He grabbed the axe from the floor without standing up, fingers closing around the handle from muscle memory alone.
He didn't run away.
He ran toward the trunk.
"You want to eat?" he yelled. "Eat this."
He drove the axe into the open maw.
Crunch.
The blade sank into soft, fleshy wood, nothing like real bark, more like muscle and pulp compressed into a shape. Green blood gushed out in a hot wave and soaked through Ren's shirt instantly.
[Warning: Corrosive Sap.] [Health -5%]
The itch started immediately. Not painful yet, just insistent. The kind of itch that informed you it intended to become a problem very soon.
'Fast. Need to finish this fast.'
Through the split in the trunk, past the ruin of the maw, he could see it. A glowing green organ pulsing behind the wood. The size of a football. Shaped like an oversized grape, wet and luminous and unmistakably alive.
The hunger moved in his chest.
Mine.
Ren let go of the axe.
He reached into the tree.
The roots came back. They whipped across his back, hard and rhythmic, like punishment.
[Health -10%]
He didn't care. His hand closed around the organ. Slippery. Hot. Throbbing with a pulse that didn't match any heartbeat he had ever felt before.
He pulled.
The tree went insane. The heads screamed at a frequency that shattered the glass on every remaining bottle in Chloe's bag. The walls vibrated. Dust fell from the ceiling in long, heavy curtains.
Ren ripped the heart out.
It sat in his hands, football-sized and still pulsing, glowing faintly green against his sap-soaked skin.
He bit into it.
It exploded.
Sweet. Battery acid sweet. Honey cut with something chemical and deeply wrong, flooding his mouth in a wave that his brain categorized simultaneously as wonderful and terrible and more, somehow, more.
He swallowed chunks without chewing. Couldn't have stopped if he tried.
Gulp. Gulp.
[Gluttony Activated.] [Consumed: Heart of the Flesh Tree.] [Critical Absorption!]
The energy wave hit him like a physical impact and knocked him flat onto the wet floor, arms spread, staring at the ceiling while his veins lit green and then faded back to normal over the course of about four seconds.
[Vitality +5] [Strength +2] [New Skill: Regeneration (Low)] [Description: You heal slowly over time. Can reattach small limbs.] [New Passive: Bark Skin (Low)] [Description: Your skin is tougher. Minor resistance to cuts.]
The whip marks on his back started itching in a different way now. A closing way. The acid burns on his arms faded like someone was erasing them one careful layer at a time.
'Convenient.'
The tree stopped moving. The heads dried up fast, the screaming faces collapsing into grey husks one after another until the basement was quiet for the first time since they had come down the stairs. The green light died. What was left was just dark wood and the smell of acid and rotting flowers and nothing else.
Ren sat up. He wiped the sap from his eyes with the back of his wrist, which helped almost not at all.
"Ren?" Chloe whispered from behind a shelf. "Is it dead?"
Ren stood up. He felt heavy. Dense. Like his skin was a size too small in a way that felt like armor.
"It's dead."
The metal chest was still tangled in the dead roots. Military grade, the kind of thing that made you wonder what someone had been planning to need it for.
He kicked the roots. They snapped like dry twigs, all that terrifying strength gone the moment the heart stopped beating.
He pulled the chest free and smashed the lock with the back of the axe.
Clang.
Latch broke clean.
He opened the lid.
No weapons. No food.
A single book. And a vial of blue liquid.
He picked up the book. The texture was wrong in a way that took him a moment to identify, and then he identified it and immediately chose not to think about it further.
[Skill Book: Analyze (Rare)] [Class Requirement: None] [Do you want to learn?]
"Yes."
The book dissolved into light that shot through his forehead. A headache spiked sharp and immediate, then vanished like it had never existed.
He looked at the vial.
[Item: High-Grade Mutagen (Type: Mental)] [Description: Forces a mutation in the brain. High chance of death. Low chance of awakening a psychic skill.]
'Save it for later,' he thought, pocketing it. 'Or maybe forever. High chance of death is a strong opening sentence.'
"Dangerous," he said out loud. "Save it."
He looked at Chloe.
[Chloe (Lvl 1)] [Status: Traumatized] [Potential: High]
He looked at the "Potential: High" for an extra second and noted it without saying anything.
"We need to move."
BOOM.
The ceiling shook. Dust fell in sheets.
Without the tree's screaming filling the basement, the other sounds bled through clearly now. The heavy steel door at the top of the stairs groaned under something massive and very patient.
SCREECH.
Metal, tearing.
"He's coming down," Chloe whispered, eyes going wide.
Ren looked around the basement. One exit. The stairs.
"We can't fight him," he said. "Not yet. Not with what I have."
The dead tree's roots had ripped the concrete floor open when they were attacking. Under the tree, behind the tangle of dead wood, was a hole. A dark drop into a round tunnel below. Old brick visible on the walls. It smelled like standing water and rust, the specific smell of systems built to be forgotten.
"There," Ren pointed.
"Into the hole?" Chloe asked, looking at the slime coating the edges.
"Better than being flattened," Ren said.
CRASH.
The door at the top of the stairs blew completely off its hinges. The landing shook as it hit the steps with a sound like a car accident.
The Crusher stepped into the stairwell. Massive, barely fitting the space, its hammer arm carving a groove in the concrete wall as it descended. It saw them from across the basement.
"ROAR!"
It charged.
"Go!" Ren pushed Chloe forward.
She jumped into the hole.
Ren followed her into the dark just as the Crusher's hammer came down on the spot where he had been standing, the impact sending a shockwave through the ground that collapsed the tunnel entrance behind him like a mouth snapping shut.
He slid for a few seconds through cold mud, and then the floor disappeared and he hit water.
Splash.
He stood. Waist-deep. Cold enough to tighten his chest on the first breath. The smell was old rain and rust and decades of neglect layered into something almost solid. Thirty feet of brick tunnel visible in either direction, vanishing into dark.
"Chloe?"
"I'm here." A cough. "I lost a shoe."
Ren activated Night Vision.
"The old storm drains," he said. "Runs under the whole campus."
"Where does it go?"
"Away from him."
He checked his status.
[Name: Ren] [Level: 4] [Health: 90%] [Hunger: 40%]
Getting stronger fast. The enemies were getting stronger faster. He filed that observation away in the part of his brain designated for problems that had no solutions yet.
"We need the city exit," he said, moving. "Campus is done. We've taken everything worth taking."
"Ren."
He stopped.
"Something's following us."
He used Tremor Sense.
She was right. Small vibrations in the water. Ripples coming from the direction of the collapsed rocks, too small and too numerous to be the Crusher.
He looked at the walls.
Mutated cockroaches. The size of shoes, shells hardened to something closer to ceramic than chitin, clinging to the brick in a shifting, skittering mass. Moving with the specific patience of things that had learned to wait for prey to stop running.
'Several hundred, at least.'
Skitter. Skitter.
Ren gripped his axe. In the cold tunnel water, the faint bioluminescence from the cockroaches' shells painted green light across his face and the wall behind him both.
He grinned and started walking toward them.
"Good," he said. "I needed a snack for the road."
