​"Lick that floor clean, Zac. You are not paid to daydream."​Bryan's baritone voice echoed loudly against the ceramic walls of the Force City Central Hospital morgue. His white silk surgical coat hung perfectly without a single speck of dirt. His crocodile leather loafers gleamed, reflecting the pale neon light from the ceiling.​Zac pressed down on the mop handle using his right hand. His left arm hung stiffly at his side. The motor nerves in that arm were completely dead due to a raging fire three years ago. His left fingers curled inward, resembling a broken bird's claw. The thick scent of formaldehyde mixed with carbolic acid stung his nostrils.​"I have cleaned this block three times since this morning, Dr. Bryan." Zac straightened his back, glaring directly into the eyes of his former best friend.​"This floor is still crawling with germs." Bryan scoffed condescendingly. He reached into his trousers pocket and tossed a silver coin.​The metal spun through the air, bounced off t

​[Absolute cardiac shock successfully executed. Welcome back to the mortal realm, Dr. Zac.]​The mechanical voice echoed in perfect unison with Zac's first gasp of air. His lungs inhaled the air violently, with a desperate greed. The bodies of the two monsters that had just lunged at his chest were blown forcefully backward. A wave of static shock erupted from behind Zac's ribcage, slamming into them like a giant hammer. The two walking corpses crashed into the row of morgue refrigeration doors, leaving the metal heavily dented and mangled.​Zac coughed violently, hacking up the foul-smelling remains of dark blood from his throat. His eyes snapped wide open, staring up at the ceiling, which was bathed in the dim red glow of the emergency siren.​The agonizing pain in his neck vanished instantly. The skin cells and muscle tissues torn apart by the monster's bite knitted themselves back together at an impossible speed. The gaping wound closed flawlessly, leaving absolutely no trace of a

​"Rot in hell, you crippled freak!"​The deafening crack of a gunshot exploded through the ruined ground-floor hallway. A bright muzzle flash erupted from the barrel of a nine-millimeter pistol. Hot lead tore through the air, aimed squarely at the center of Zac's forehead. The firing distance was less than five meters, making the projectile virtually impossible for a normal human to dodge.​[Critical danger warning. High-velocity projectile detected. Activating level-five maximum neural reflex compensation mode.]​The system's mechanical voice buzzed just a fraction of a second before the bullet arrived. Time immediately surrounding Zac seemed to slow down drastically. The dusty air in the hallway appeared to freeze in place. Zac could clearly see the spiraling grooves of the bullet spinning rapidly toward his face.​Zac tilted his head slightly to the left. The hot projectile whizzed past his right ear, singeing a few strands of his hair, before burying itself deep into the concrete

"Break down that wooden door and destroy every breathing thing inside!"​Captain Viktor's voice was heavy and muffled behind his protective mask. The execution order echoed with crystal clarity in Zac's ears, piercing right through the thick door of the medical records room. The synchronized stomping of steel-toed tactical boots advanced steadily toward his hiding place.​Zac's eyes scanned the pitch-black room at lightning speed. He spotted two massive medical oxygen tanks standing upright in the corner of the room, right beside a storage rack filled with liquid chemicals. An incredibly insane and highly risky idea flashed through his genius mind.​"What is the absolute maximum pressure inside those green oxygen tanks?" Zac asked rapidly inside his head.​[A standard medical oxygen tank holds a maximum pressure of two thousand psi. A sudden, critical breach of the main valve will generate a projectile thrust completely equivalent to the blast of a mid-level improvised explosive devic

​"Destroy the southern sector right now!"​Captain Viktor's roar echoed from the main hallway, shattering the silence of the hospital. The giant of a man wasted absolutely no time trying to figure out his subordinate's fate. He responded to Zac's threat with the most brutal military action possible. He lowered the barrel of his assault rifle. He raised the forty-millimeter grenade launcher mounted beneath the main barrel.​"Burn to ashes, you crippled bastard!" Captain Viktor pulled the grenade launcher's trigger without a single ounce of hesitation.​Zac had barely tossed the communication radio to the floor when the whistle of the projectile sliced through the air. The high-explosive grenade struck the concrete wall of the medicine storage room right in front of Zac's face.​A devastating explosion instantly tore the building's structure apart.​An orange shockwave violently swept through the entire room. The concrete walls shattered into thousands of pieces, turning into lethal pro
