[University Science Building, Basement Storage Level, Day 3 Post-Skyfall, 10:14 AM]
The roots did not breach the surface slowly. They erupted the way a closed fist delivers an uppercut, violently punching through the thick epoxy resin floor in heavy sprays of pulverized grey concrete and chalky dust. Five distinct tendrils broke through in the first second. Each root matched the exact circumference of Ren's forearm, terminating in a sharply tapered point hardened to a density far exceeding natural wood. A sickly, bioluminescent green light pulsed rapidly through the exposed vein-network of the tree's massive root system, illuminating the cavernous basement from below. Every shattered fissure in the floorboards radiated the toxic glow. The smell hit the stagnant air immediately, a layered, suffocating stench of rotting gardenias, overripe fruit, and the sharp, metallic tang of raw copper.
Ren shifted his weight before the primary root even crested the epoxy.
His Tremor Sense tracked their approach three full seconds before they shattered the floor. He felt the intense pressure differentials grinding through the substrate and solid stone, telegraphing their exact upward trajectories. He registered the next cluster surging from his left flank, immediately stepping hard to his right. SHUKK. The hardened wooden points violently pierced the empty space his left thigh had occupied a fraction of a second prior, slamming upward into the steel underside of an industrial equipment rack with enough kinetic force to tip the heavy metal structure entirely over.
The central tree screamed. SKREEEEEE.
All twelve human heads embedded in the upper branches snapped their jaws open at wildly varying widths, projecting different agonizing pitches that layered over each other into a deeply unnatural dissonance. Their individual eyes rolled independently in their sockets, frantically tracking his movements across the ruined basement floor. The thick grey-brown bark of the central trunk had aggressively fused upward into their jawlines, physically swallowing the lower halves of their human faces from the outside in.
Tear the meat. Protect the amber core. Feed the roots.
A chaotic, fragmented loop of panic radiated from the entity. Twelve partial minds running the exact same defensive alarm in parallel.
Ren swung the heavy fire axe in a brutal horizontal arc. The high-carbon steel blade, perfectly weighted for breaching structural doors, easily compensated for his lowered Strength stat. The axe head sheared completely through the closest attacking root like wet paper. The severed appendage instantly sprayed highly pressurized, glowing green fluid across the floor. Hissssss. The acidic sap melted into the epoxy resin, burning the air with the smell of ozone and melting plastic.
The twelve heads shrieked louder, their fused throats vibrating violently.
Six additional roots surged upward simultaneously in a perfect radial pattern centered dead on his physical coordinates. He caught the dense vibration tearing through the floorboards a half-second before the concrete buckled.
"Chloe!" Ren shouted over the noise. "The ammonia!"
She stood pressed flat against the far northern wall, thirty feet away. Her knuckles were white as she pressed both trembling hands tightly over her nose and mouth. Her dark, shoulder-length hair clung to her sweat-slicked cheeks, her eyes wide and panicked, but she remained functional. She ripped the heavy canvas bag open. Glass bottles clattered loudly against each other.
If he dies, I'm alone in the dark with this thing. Please get up. Please.
Ren lacked the time to check her progress. Two thick roots breached the concrete directly inside his defensive guard, spaced far too closely together to allow a proper swing. He dropped the axe handle into a horizontal block, catching the tapered points of both roots squarely on the thick wooden shaft. The immense kinetic impact traveled sharply up his forearms and directly into his shoulder joints. His heavy boots skidded backward six exact inches across the slick epoxy before his Strength stat checked against the overwhelming pressure and held firm.
The hardened root tips dug deeply into the wood. The handle emitted a sharp, cracking sound.
He violently shoved back, redirecting the massive force upward. The roots stabbed harmlessly through the open air on either side of his ribs, burying themselves deeply into the cinderblock wall behind him. Ren instantly released the axe with his left hand, wrapping his bare fingers tightly around the pulsing green root-stem. He engaged his Strength stat entirely, the dense muscles in his back and shoulders loading up as he ripped the root backward. KRAKK. The appendage tore entirely out of the masonry, bringing a thick shower of chalky mortar dust with it. Using the sheer momentum of his rotation, he swung the torn root like a massive whip directly into a fresh cluster trying to surface near the small wooden chest at the tree's base, smashing them back into the floor before they reached full extension.
The chest sat exactly ten meters away.
His Eagle Eye skill resolved the visual lock with perfect clarity. A corroded brass padlock hung heavily on the front, the thick metal shackle partially dissolved by the acidic vines that had aggressively grown over it during the past three days. Organic plant tissue and rusted metal had seamlessly fused at the contact points. A deep, amber-gold light bled heavily through the seams of the rotting wood, entirely overpowering the sickly green glow of the tree's veins.
The internal hunger recognized the prize from twenty feet away. It was an ancient, demanding pull anchored deep beneath his Gluttony skill, forcefully orienting his entire biological focus toward the chest like a magnetic compass locking onto true north.
"Now!" he commanded.
Chloe hurled the heavy glass bottle of ammonia. Her throwing mechanics were entirely flawed, but the central trunk spanned the width of a commercial refrigerator, dominating the center of the room. The glass shattered violently against the thick bark, splashing the raw chemical in a wide, dripping radius. She already held the gallon jug of industrial bleach uncapped, launching it forward with both hands.
The resulting chemical reaction was instantaneous. The improper mixing ratio and ventilated basement space prevented the formation of a lethal mustard gas cloud, creating instead a violently corrosive, localized burn. The thick bark instantly flashed from grey-brown to a stark, dead white, then immediately blackened into charred ruin. The massive tree recoiled aggressively. The entire biological structure pulled inward and upward simultaneously. Dozens of roots aggressively withdrew from the concrete floor in a rapid, sequential retreat, sounding like thick plungers ripping away from wet stone.
The twelve fused heads released a single, unified wail of pure agony.
Ren broke into a dead sprint. He charged straight at the tree's exposed base, keeping his axe low. A thick branch swept downward, carrying a screaming head with wildly snapping teeth aimed directly at his jawline. He dropped his center of gravity, ducking cleanly under the bite, and drove the heavy axe blade deeply into the primary root-cluster choking the wooden chest. Two consecutive, brutal chops severed the thickest vine completely. The release of tension caused the small chest to drop six inches, hanging loosely by a single vine.
He flipped the axe, smashing the flat of the heavy steel head directly against the corroded brass padlock. The weakened shackle snapped cleanly. He yanked the splintered lid backward.
A single seed rested on a bed of dried bark fibers and coagulated green fluid. It matched the size of a large, misshapen egg, colored in a raw, crystalline amber. The object emitted a slow, ambient radiation of heat rather than a direct light source. Deep within the faceted surface, unidentifiable shapes rotated slowly.
[Primal Mutation Seed - System Origin] [Unclassified. Consume at your own discretion.]
A jagged root violently punched entirely through the splintered side of the chest, driving its tapered wooden point straight through the back of his left hand.
The pain registered cleanly and deeply. The thick spike impaled his palm completely, forcing his fingers to spasm and open involuntarily. The glowing seed dropped heavily back into the rot. Ren instantly reached in with his uninjured right hand, snatching the amber core, and violently ripped his impaled left hand entirely off the jagged wood in one fluid, brutal motion. The exit wound tore widely, spilling thick, dark blood heavily across his knuckles and wrists.
He shoved the entire seed into his mouth.
It lacked any biological texture. It tasted exactly like the sharp, deep-mineral scent of ozone during a heavy lightning strike, dissolving instantly against his tongue in a building, electrical heat. He swallowed forcefully.
The tree screamed continuously for three full seconds, the intense frequency aggressively rattling the steel equipment shelving across the room.
[Gluttony Activated.] [Consumed: Primal Mutation Seed - System Origin.] [SYSTEM RECOGNITION EVENT.] [Analyzing consumption profile...] [Rat. Student. Python. Void Parasite. Crow. Spider. Primal Seed.] [Profile classification: Apex Convergence.] [New Title Unlocked: Devourer.] [Effect: All future Gluttony gains increased by 30%. Consumed entities' highest passive skill flagged for potential extraction.] [New Active Skill: Assimilate.] [Description: Once per day, fully consume a target to extract its dominant genetic trait. Trait quality scales with target level.] [Health fully restored.] [Stamina fully restored.]
The ruined flesh of his left hand regenerated instantly. The gaping puncture wound aggressively closed from the inside out, the torn muscles and tendons knitting perfectly together in a fraction of a second. The smeared blood quickly dried and flaked away, leaving smooth, unblemished skin in its wake. The intense electrical warmth from the seed radiated heavily outward from his sternum.
He felt the massive entity looming directly above him.
His Tremor Sense registered the complete withdrawal of the root system. The remaining vines pulled tightly against the central trunk as the horrific ammonia burn continued eating slowly through the blackened bark. The twelve screaming heads abruptly fell dead silent. A dozen mouths snapped shut. A dozen pairs of frantic eyes locked directly onto his position, their collective expression shifting rapidly from aggressive alarm into cautious terror.
Ren tilted his head backward, locking eyes with the monstrosity.
[Mutated Flesh Tree (Lvl 7)]
The system question marks had vanished entirely. He analyzed the massive trunk, the twelve human faces fused into the upper canopy, the slow chemical decay destroying its armor. His internal hunger calculated the tree's worth just as it had evaluated the rat in the closet, but the newly acquired Assimilate skill aggressively pushed a secondary option to the forefront of his mind. A Level 7 entity. Pheromone production for biological crowd control. A wide-range root sensory network.
The massive tree shuddered violently, bracing its remaining vines tightly against the shattered concrete.
Ren stepped calmly to the base of the blackened trunk, gripping the heavy fire axe in his right hand. He raised his left arm, pressing his bare palm entirely flat against the thick, pulsing bark.
The Assimilate skill engaged instantly.
The enormous flesh tree went entirely rigid. The cavernous basement fell completely silent for ten consecutive seconds, save for the distant, rhythmic BOOM BOOM of the massive Crusher mutant hammering against a steel security door two floors above, the low electrical hum of the cryogenic units down the sublevel corridor, and Chloe's rapid, panicked breathing thirty feet behind him.
[Assimilate Complete.] [Dominant Trait Extracted: Rootsense.] [New Passive: Rootsense.] [Description: Extends Tremor Sense range to 200 meters. Can map structural layouts through ground contact.]
The massive entity collapsed inward. It lost structural integrity completely, folding down against the broken floorboards in heavy, dead sections. The remaining roots went entirely limp. The twelve human heads slowly closed their eyes as the sickly green bioluminescence fading from the vein network turned grey, then pitched into absolute darkness. The cloying stench of rotting gardenias vanished. The room smelled only of wet, dead wood, sharp chemical bleach, and chalky concrete dust.
Ren stood perfectly still in the dim lighting. His newly acquired Rootsense snapped violently open.
The input hit his neurological system like a secondary brain activating. Unlike the localized Tremor Sense, the new ability instantly mapped two hundred meters of continuous, three-dimensional geometry in every possible direction. He felt the heavy Crusher pacing aggressively in the upper lobby, its massive footfalls registering as heavy seismic impacts. He located six cooling, neutralized mutant corpses scattered throughout the adjacent basement corridor. He pinpointed Dr. Yuen hiding in the deeper sublevel, her steady, terrified pulse projecting a deep violet resonance that felt entirely different from physical vibration.
He mapped the devastated city standing beyond the concrete walls. Thousands of moving physical masses. Falling architecture. Uncontrolled fires consuming steel beams. And exactly three blocks north, heavily wrapped around the central skyscraper, he detected a biological signature so impossibly massive and hot that it registered as a shifting geological tectonic plate rather than a living creature.
Ren exhaled a long, slow breath.
"You ate a tree," Chloe said, her voice completely hollow.
He turned his head slowly. She remained pressed firmly against the far wall, her hands resting limply at her sides. She stared blankly at the colossal pile of dead, folded wood, and then directly at his face. Her brown eyes carried that same flat, deadened exhaustion she had worn since the ceiling spider encounter.
"I assimilated it," Ren answered smoothly.
"Is that..." She swallowed hard, her jaw tight. "Is that different from eating it?"
"Less chewing."
Ren grips the heavy wooden handle of the fire axe tightly in his right fist, turning his shoulders squarely toward the northern staircase leading toward the heavy pressure door, and he begins taking long, measured strides across the shattered concrete.
