I Was Reborn as the Apocalypse's Weakest Healer

Chapter 3: Silent Echoes

"Deal," Lucas whispered, the word tasting like copper and ash.

Valentina didn’t offer a handshake. She simply turned on her heel, her boots making almost no sound on the cracked pavement. "Keep up, Lucas. We don’t have all night, and the shadows here have teeth."

Lucas scrambled to his feet, his body protesting every movement. The phantom ache in his forearm from healing her earlier persisted, a dull, rhythmic throb that pulsed in time with his heartbeat. He looked at the holographic display flickering in his peripheral vision—a reminder that he was effectively a walking target for a cosmic debt collector.

[SYSTEM DEBT: 999,999 ESSENCE CREDITS REMAINING.]

"Are you always this charming, or am I getting the premium treatment?" Lucas muttered, jogging to catch up.

Valentina glanced back over her shoulder, her violet eyes cutting through the gloom. "I’m an asset manager, not a tour guide. Don't waste my breath on small talk."

"Asset manager," Lucas snorted, hopping over a rusted fuel tank. "Is that what you call kidnappers these days?"

"You’re alive, aren't you? If I were kidnapping you, I wouldn't have bothered patching you up. I would’ve just harvested the energy from your corpse." She stopped abruptly, holding up a fist.

Lucas skidded to a halt behind her. The silence of the ruins was absolute, save for the whistling wind.

"What is it?" he whispered.

"Infected," she said, her voice barely audible. "Move into the shadows. Now."

They pressed themselves against the side of a collapsed highway overpass. Below them, a section of the road had buckled, creating a natural trench. A group of creatures moved through the debris—humanoid, gaunt, their skin stretched thin over bones that seemed to shift and grow in ways human anatomy shouldn't. They didn't walk; they skittered, clicking their teeth like insects.

"What are those things?" Lucas’s heart hammered against his ribs.

"Discarded experiments," Valentina said, her hand dropping to a sleek, metallic rod strapped to her thigh. "The world didn't just end, Lucas. It got repurposed. Those things? They’re just looking for biomass. Don't make a sound."

Lucas held his breath, watching as one of the creatures paused, its head snapping toward their position. It sniffed the air—a wet, rattling inhalation.

"It smells us," Lucas whispered.

"I know." Valentina gripped her weapon. "Get ready. If they charge, you stay behind me. Don't heal me unless I tell you to. Understood?"

"Why? I thought you said I was your partner."

"You’re a green recruit who doesn't know the difference between a skirmish and a massacre. Stay behind me and observe. That’s an order."

The creature shrieked—a high, discordant sound that shattered the silence. Its companions surged forward, moving with unnatural speed. Valentina moved instantly, vaulting over the rubble and into the open. She was a blur of motion, her rod elongating into a humming energy blade that cut through the darkness like a beacon.

"Hey! Over here, you ugly bastards!" she shouted, her voice cold and commanding.

The creatures swarmed her. It was a chaotic dance of gore and light. Valentina moved with a fluid, terrifying precision, parrying strikes and delivering counter-blows that disintegrated the creatures upon contact. But there were too many. One of them, faster than the rest, lunged from behind a pillar, its jagged, bone-like claws raking across Valentina’s side.

She spun, decapitating it, but her movement faltered. A dark, viscous liquid began to bloom across her tactical vest.

"Valentina!" Lucas lunged forward, ignoring her order.

"I told you to stay back!" she snarled, parrying another blow, though her left arm was now sluggish.

"You’re bleeding out!" Lucas shouted, ducking under a stray claw. He grabbed her shoulder, his hands glowing with that familiar, violent warmth.

"Not now, you idiot!"

"Shut up and let me work!"

Lucas pushed his energy into her. He felt the trauma of the deep gash migrate into his own body. His vision shattered into white light, and he fell to his knees as the agony hit him with the force of a falling building. His left arm erupted in sensation—a searing, tearing pain that felt like hot wires were being pulled through his nerves.

"Dammit," Valentina breathed, her expression shifting from annoyance to a strange, sharp focus as her wound sealed instantly under his touch. She didn't waste the opening. She turned, her blade lashing out in a wide arc, cleaving the remaining creatures into silence.

The sudden quiet was deafening.

Lucas was on the ground, curled into a ball, his breathing shallow and ragged. His arm felt like it was still being shredded by invisible blades. He squeezed his eyes shut, his teeth grinding together to suppress a scream.

Valentina stood over him, her chest heaving, her violet eyes scanning the perimeter for more threats. Once she was sure they were alone, she dropped to one knee beside him.

"You’re an idiot," she murmured, though the edge in her voice had softened. "I told you not to burn yourself out."

"You're... welcome," Lucas wheezed, his voice thin and trembling.

"Yeah, yeah. Keep your energy up." She reached out, grasping his jaw to tilt his head toward her. "Lucas, look at me. Stay awake."

"I... I can't," he slurred. The world was swimming, a dark, heavy tide pulling him under. Every heartbeat sent a fresh jolt of agony down his arm, and the toll was becoming too much for his exhausted system.

"You don't get to pass out in the middle of a war zone," she said, though she shifted her weight so he was leaning against her. "Come on, move your feet."

"Just... let me sleep... for a minute," Lucas groaned. His eyelids fluttered, his consciousness fraying like old rope. The pain was receding, replaced by a deep, hollow numbness that felt just as dangerous.

"Lucas!" She slapped his cheek, not hard, but enough to snap his head back. "Wake up!"

"I am... awake," he lied. He sank deeper, his head falling against her shoulder. His body had reached its limit. The debt was being paid in full, and his mind couldn't handle the interest.

Valentina let out a sharp, frustrated breath. She pulled him closer, hoisting him up with surprising strength. "Fine. If you’re going to be a liability, you’re going to be a portable one."

She began to move, carrying him toward the shelter of a skeletal high-rise nearby. "You’re lucky you’re useful, little spark. Any other healer would have been left for the scavengers."

As she moved through the dark, the world faded to black for Lucas. But even in the darkness, the System persisted.

You think you are clever, little spark?

The voice wasn't his. It was ancient, cold, and melodic, echoing in the back of his mind as if from the bottom of a well.

Who... who are you? Lucas tried to think, but his thoughts were sluggish.

I am the one who remains when the flesh fails, the voice whispered, accompanied by the faint, shimmering sound of golden light. I am Asclepius. You carry a heavy debt, boy. Do you wish to see it paid in full, or will you let it consume you?

I just want to survive, Lucas thought, his consciousness slipping further away.

Survival is a choice, the voice echoed, fading as Lucas succumbed to a deep, feverish sleep. But power... power is a contract. We shall see what you are worth when you wake.

Valentina found a secure corner in the ruined office building. She set Lucas down on a relatively clean patch of floor, her hands checking his pulse. It was steady, if a bit frantic. She tore a strip of fabric from his sleeve to inspect the wound on his arm—a perfect, mirror-image scar of the one he had healed on her.

She sat back, watching him in the dim moonlight filtering through the broken windows.

"Survive the night, little spark," she whispered to the quiet room. "I’m counting on you."
