  • Chapter 49: The Blood-Stained White Corridor

    The girl wasn’t mute because of a physical disability. She had chosen silence. And now, she broke that silence only to save the life of an awkward barista.“Y-you… spoke,” Raka whispered weakly. A bitter laugh bubbled with blood from his lips. “And you’re telling me to hold on? When I feel like a lump of ground meat?”Luna didn’t respond.With a rough pull that made Raka’s shoulder creak painfully, she jerked his body upward, dragging him past the third-floor window frame.THUD!Both of them tumbled onto the hospital floor.Raka coughed violently, vomiting more dark blood onto the dirty white tiles, while Luna lay beside him, breathing heavily.Outside the window came the frantic flapping of wings, followed by a very inelegant landing.“Honk!”&

  • Chapter 48: The Hospital Gate

    The monsters no longer cared about Raka, Luna, or Baginda standing stiffly at the edge of the blockade. Their sense of smell had locked onto the nearest source of fresh blood.“Help! Help me!”The dreadlocked gang leader tried to crawl away from the pile of motorcycles, using hands whose fingers Raka had already broken.A mutant dog monster leapt from the top of a wrecked car and immediately sank its massive jaws into the man’s calf.A piercing scream shattered the evening air, followed by the wet sound of flesh tearing and bones being ripped apart.The slaughter feast had begun.Raka turned his face away, his stomach churning with nausea.“Luna, Baginda, we’re leaving,” Raka whispered hoarsely, pulling the girl’s arm with his left hand. “Now. While they’re busy having di

  • Chapter 47: Symphony of Exhaust Pipes

    The dreadlocked gang leader riding the modified black chopper burst into loud laughter.His right hand spun the barbed chain in the air, preparing to swing it at Raka’s head on the next pass.“Where are you going to run now, Little Rabbit?!” he shouted, his voice nearly swallowed by the thunder of engines. “You can’t run faster than a 1200cc V-twin engine!”Raka stood with his back to Luna, shielding both her and Baginda. His right shoulder throbbed painfully, forcing him to lean forward slightly.He glanced at Luna.She stood upright, gripping her twin knives tightly, her sharp eyes tracking the motorcycles’ movements.Luna was searching for an opening, the right timing to throw her knives. But the bikes were too fast, and the dust too thick.If she missed, she would lose her weapons.&nbs

    “Luna.”Raka woke Luna with a light tap on the shoulder and pointed at the three distant figures with his index finger.The girl wasted no time. She rose, grabbed her bow, and nodded. They immediately moved away from the damp bus stop before the criminals’ binoculars locked onto their position.An hour later, the three of them had reached the outskirts of the district where St. Mary’s Hospital stood.The white building now rose clearly about three blocks ahead of them. Hope began to spark in Raka’s chest.But in the apocalypse, hope always came with a price.They hid behind a pile of concrete debris from a collapsed office building.Ahead of them, the main road leading directly to the hospital was completely blocked. Not by monsters. Not by burned-out city buses.But by r

  • Chapter 45: Hypothermia and an Embrace

    “One… two… three…”Raka began performing chest compressions, recalling fragments of CPR training he had once seen in an internet video years ago.His movements were clumsy because of his injured right shoulder, but desperation gave him extra strength.“Come on, breathe! Don’t die here!”He pinched Luna’s nose, took a deep breath, and gave her rescue breathing. The air he exhaled felt useless against the girl’s ice-cold lips.‘System! What should I do?!’ Raka shouted in his mind.His hands continued pressing down on Luna’s chest again and again.[System: Emergency Scan: No heartbeat detected. Lungs filled with contaminated fluid. Survival chance: 0.1%. You are not a doctor, Raka. Stop before you break her ribs.]<
