ECHOPRAXIA: The Last Heartbeat

The high-frequency hum of the mechanical vibration blade was the only sound permitted to exist in the bowels of Neo-Jakarta. It was a cruel, thin whistle, vibrating at a pitch that bypassed the human ear and settled directly into the marrow of the bone. In the suffocating darkness of the Sector 7 underground tunnels, the air was a thick, gelatinous soup of moisture and the shimmering, iridescent haze of Echo-V gas. Every breath felt like inhaling wet velvet. V held the knife with a hand that did not tremble. His pulse was a flat line of icy resolve, buried so deep beneath his consciousness that it didn't even register on the bioluminescent sensors embedded in his tactical glove. Before him, Kens was pinned against the weeping concrete wall. The man’s eyes were two white orbs of pure, unadulterated terror, bulging in the dim light. Kens opened his mouth to plead, to scream, to call out the name of the man who had been his best friend since the academy, but no sound emerged. V had already severed the necessary nerves with the precision of a master clockmaker. "Don't worry, Kens," V whispered, his voice a low, melodic rasp that barely disturbed the air. "The gas won't hear us. I am being very, very careful." The tip of the vibration blade touched Kens’s sternum. With a surgical flick of the wrist, the blade hummed through the bone. It didn't crunch; it melted through the calcium like a hot wire through wax. V watched with a detached, clinical fascination as the chest cavity opened. He could see the lungs struggling to expand, a pair of panicked birds trapped in a cage of ribs. "Why are you doing this, Delon?" Kens’s eyes seemed to scream the question, even as his life force began to drain into the shadows. V reached into the opening. His fingers were warm, slick with the lifeblood of a comrade, but he did not flinch. He found the pulsing mass of the heart and pinched the carotid arteries between his thumb and forefinger. It was a delicate maneuver, designed to prevent the internal pressure from causing a spray. A single splash of blood hitting the floor would create a vibration frequency high enough to ignite the Echo-V gas, turning the tunnel into a pressurized furnace. "I am not Delon right now," V replied, his eyes fixed on the small, crystalline implant nestled against the aorta. "Delon is sleeping. He doesn't like the sight of blood. But I... I find it quite beautiful in this light." With a sharp, rhythmic tug, V disconnected the Beat-Core. The tiny device flickered a violent, frantic red before fading to a dull, dead amber. As the core left the body, the light in Kens’s eyes simply went out. The body slumped, a discarded shell of meat and uniform, sliding down the wall into a silent heap. V turned his attention to the corner of the room. Grek was already there, lying in a tangled mess of limbs. His chest was an empty, gaping crater, the ribs splayed outward like the petals of a dark flower. V had already harvested his core. The two devices now sat in a lead-lined pouch at V’s hip, their signals muffled so the central military radar would perceive nothing but a localized ghost in the system. "Two brothers down," V muttered to the empty air. "And the world is still so very quiet." He stood up, wiping the blade on the back of his tactical vest. The silence of the tunnel was absolute, broken only by the faint drip of condensation from the overhead pipes. He looked at the bodies, feeling a strange sense of accomplishment. The mission—the internal mission that only he understood—was proceeding exactly as planned. "You were always the loud one, Grek," V said, looking at the second corpse. "You would have triggered the gas within seconds of the first shot. This is much cleaner. You should thank me for giving you such a peaceful end." Suddenly, a violent tremor shook the frame of the man standing over the dead. The cold, obsidian void in his eyes began to crack, replaced by a frantic, jagged light. The vibration knife slipped from his fingers, clattering onto the soft, blood-soaked fabric of Kens’s sleeve. "V? What... where am I?" a different voice emerged from the same throat. Delon felt the world rush back in like a physical blow to the stomach. The first thing he registered was the heat. The air in the tunnel felt like it was boiling, thick with the metallic, copper stench of fresh blood. He gasped, but the sound caught in his throat, turning into a silent, agonizing retch. He fell to his knees, his hands landing in a warm, sticky pool that had gathered around his boots. "Kens? Grek?" Delon whispered, his voice trembling with a sudden, sharp edge of hysteria. "Guys, wake up. This isn't funny. Stop playing around." He reached out, his fingers brushing against Kens’s cold, waxy cheek. There was no response. He looked down at his own hands and saw the deep, shimmering crimson staining his skin up to the elbows. He saw the gaping holes in their chests. He saw the clinical precision of the wounds—wounds that could only be made by a vibration blade. "No," Delon breathed, his heart beginning to thud against his ribs like a trapped animal. "No, no, no. I didn't do this. I couldn't have." He looked around the tunnel, his eyes darting frantically through the haze. There was no one else. No enemy soldiers, no insurgents, no monsters in the dark—only him and the two men he had called his brothers. The disorientation was a heavy weight, pressing down on his skull until his vision blurred. He remembered walking into the tunnel with them. He remembered laughing about a girl in Sektor 3. And then... nothing. Just a vast, cold silence. "I have to move," he told himself, the words a desperate mantra. "I have to get rid of the evidence. If the patrol finds me like this, I'm dead." He grabbed Kens by the heavy tactical webbing of his vest. The body was dead weight, dragging through the blood with a sickening, wet sound. Delon looked at his wrist sensor. The numbers were climbing. 85 BPM. 90 BPM. 92 BPM. "Keep it down, Delon," he hissed to himself, his teeth gritting so hard they ached. "If you hit one hundred, the gas takes you too. Breathe. Just breathe." He dragged the bodies toward the chemical waste tanks at the end of the corridor. These vats were filled with a caustic neutralizing agent for the Echo-V gas, but they were more than capable of dissolving organic tissue into an unrecognizable slurry. One by one, he pushed them in. The hiss of the chemicals felt like a scream in the silence. "I'm sorry," Delon whispered as the last of Grek’s uniform disappeared beneath the surface of the acid. "I don't know what happened to me. I'm so sorry." He stood over the vats for a moment, his chest heaving as he fought to bring his heart rate back into the green zone. He looked at the empty tunnel, the bloodstains on the floor already beginning to react with the gas, turning into a dark, harmless soot. "You did what you had to do," a voice whispered from the back of his mind. It was a cold, familiar voice, but Delon pushed it away, burying it under a layer of pure, unadulterated fear. "I need to get out of here," he said aloud, his voice cracking. "I need to wash this off. I need to find Elsa." He turned and began to run through the service ducts, his boots making no sound on the rubberized flooring. He was a ghost in the machine, a murderer in a hero’s uniform, moving through the veins of a city that was already dead. The memory of the knife slicing through bone played on a loop in his mind, a silent movie he couldn't turn off. "I'm still me," he lied to the darkness as he climbed toward the surface. "I'm still Delon." But as he reached the barracks and saw his reflection in the sterile light of the washroom, he saw the truth. Underneath his fingernails, a thin, dark line of blood remained—a permanent record of the minute he had spent as a monster. "You can wash the skin, Delon," the voice in his head chuckled. "But the heart... the heart is mine."
