The moment they crossed the threshold, the air changed.

  It wasn’t just colder. It was heavier, thick with something that made Yukio’s chest tighten with every breath.

  The stone corridor ahead stretched downward at a shallow angle, walls carved from ancient rock streaked with dark stains that looked far too organic to be mineral deposits. The faint glow of Aurumspire’s warding runes behind them faded quickly, swallowed by shadow.

  Michibiki stopped after only a few steps.

  “…This isn’t normal mana,”

  She said quietly.

  She raised one hand, fingers weaving a practiced sigil.

  “Light Magic: Blessing of the Luminous Veil.”

  Soft light burst outward, wrapping around each of them like a translucent cloak. The pressure in the air eased just slightly, enough that Yukio could breathe without feeling like something was pressing on his lungs.

  Kaede flexed her fingers, watching the light cling to her skin.

  “Good call. Feels like the place is trying to crawl inside my mouth.”

  Yukio forced a small grin.

  “Glad I’m not the only one getting bad vibes.”

  They moved deeper.

  The ruins widened into an old passageway, tall enough for giants once, judging by the scale. The walls were etched with symbols Yukio didn’t recognize, spirals, jagged lines, angular runes that seemed to twist if he stared too long.

  “Those aren’t dungeon markings,”

  Michibiki murmured.

  “They’re… older.”

  Yukio swallowed. The Threads brushed against his awareness again, restless and uneasy.

  “…They don’t like this place,”

  He said.

  Kaede snorted.

  “First time your weird fate thing is nervous?”

  “Yeah,”

  Yukio replied.

  “And I don’t like it.”

  A low growl echoed down the corridor.

  All three froze.

  The sound came again, closer this time. Multiple throats. Hungry.

  From the darkness ahead, shapes emerged.

  Wolves.

  But not really.

  Their bodies were elongated and twisted, joints bent at wrong angles. Patches of fur had sloughed off, revealing gray, scarred flesh beneath. Their eyes burned a sickly crimson, and black veins pulsed visibly along their necks and limbs.

  The stench hit them seconds later.

  Michibiki and Yukio activated Appraise simultaneously.

  Monster Type: Grotesque Wolf

  Level: 70

  Threat Level: Dangerous

  Status: Corrupted

  Kaede tightened her grip on her hammer.

  “Yeah. Definitely not forest wildlife.”

  The wolves didn’t hesitate.

  They lunged.

  Kaede stepped forward first, wind compressing beneath her feet as she slammed her hammer into the lead wolf mid-leap. The impact shattered stone and sent the creature crashing into the wall in a burst of dust and blackened blood.

  Michibiki followed instantly, light forming into spears that struck two more wolves, pinning them to the ground with sizzling precision.

  Yukio moved to support.

  And the wolves turned.

  All of them.

  Their snarling faces snapped toward him in unison.

  “…That’s not good,”

  He muttered.

  They charged him.

  Vaelora’s voice snapped into his head.

  “Yuki, don’t. Not yet.”

  He instinctively reached for the Wheel.

  “Everything here is tilted against you,”

  Vaelora warned.

  “This place doesn’t follow probability the way it should.”

  A wolf leapt at him.

  Yukio barely rolled aside, claws slicing through the air where his head had been. He threw a wind-enhanced kick, but the force felt… off. Weaker. The creature skidded back but didn’t fall.

  “What the hell?”

  Yukio hissed.

  Another wolf slammed into him, knocking him across the stone floor. Pain flared as his shoulder struck the ground.

  “Yukio!”

  Michibiki shouted.

  Kaede roared, her aura flaring as she crushed a wolf’s skull beneath her hammer, then spun, intercepting another mid-charge before it could reach him.

  Michibiki raised her hands, eyes blazing.

  “Light Magic: Radiant Severance!”

  A wave of condensed light tore through the remaining wolves, ripping the corruption apart from the inside. The creatures collapsed, bodies dissolving into foul smoke that quickly dispersed.

  Silence followed.

  Yukio pushed himself up slowly, wincing.

  This book is hosted on another platform. Read the official version and support the author's work.

  “…Okay. That sucked.”

  Kaede offered him a hand, hauling him to his feet.

  “You good?”

  “Yeah,”

  He muttered.

  “Just… that felt wrong.”

  Michibiki knelt beside him, scanning him carefully.

  “They were focused on you. Not the strongest target. Not the closest.”

  “…Me,”

  Yukio finished.

  Vaelora sighed softly in his mind.

  “They’re reacting to the Threads. Or what’s attached to them.”

  Kaede frowned, glancing down the corridor.

  “So this place hates him.”

  “Seems mutual,”

  Yukio said.

  They pressed on.

  The deeper they went, the more the ruins changed.

  Passages branched unnaturally, looping back on themselves in ways that shouldn’t have been possible. The symbols on the walls grew denser, sharper, etched with purpose rather than decoration.

  More monsters emerged.

  Not in packs anymore.

  They came in formations.

  Corrupted beasts flanked each other, retreating when pressed, drawing Kaede forward while others circled wide. Some feigned injury, only to strike when someone turned away.

  “They’re thinking,”

  Kaede growled after crushing another twisted creature.

  “That pisses me off.”

  Michibiki nodded grimly.

  “This isn’t instinct. Something’s directing them.”

  Yukio stayed back this time, supporting where he could, but every spell felt sluggish, like the mana resisted him. Even simple wind magic drained more than it should have.

  The Threads pulsed in warning.

  “Not yet,”

  Vaelora repeated gently.

  “Whatever’s down here… it wants you to use them.”

  That thought chilled him more than the ruins ever could.

  The aftermath of the wolves left the ruins unnaturally quiet.

  No echoes. No scuttling. Not even the faint drip of water against stone.

  Only the low hum of corrupted mana lingering in the air, clinging to the walls like smoke that refused to dissipate.

  The trio moved forward carefully, boots crunching over fractured stone and scorched markings left behind by the fight. The deeper they went, the older everything felt. The architecture shifted subtly, arches carved with precision rather than brute strength, corridors shaped with intention instead of convenience.

  Yukio dragged his fingers lightly along the wall as they walked, frowning.

  “This place doesn’t feel like abandoned,”

  He muttered.

  Michibiki nodded.

  “Monsters now occupy these ruins, humans used to live here.This was built by the city's ancestors.”

  Kaede snorted quietly.

  “Built by people who really liked creepy symbols, apparently.”

  She wasn’t wrong.

  As they rounded a bend, the corridor widened into a circular chamber. The walls curved upward into a domed ceiling, faintly illuminated by veins of mana embedded deep within the stone. Symbols lined the walls in repeating patterns most eroded by time, others intentionally preserved.

  Michibiki slowed, her gaze locking onto one symbol in particular.

  “…Stop.”

  Yukio and Kaede halted immediately.

  Michibiki stepped closer to the wall and raised her hand just short of touching it.

  There, etched into the stone with deliberate precision, was a crest.

  A crescent moon.

  Cradled in its hollow center was a ring of ash, etched so deeply that the stone itself looked burned.

  Kaede’s breath caught.

  Her vision tunneled.

  For a split second, the chamber vanished.

  Flames roared.

  Smoke choked her lungs.

  The shadowed figure hovered above the burning streets, black armor etched with the same symbol, watching her kneel beside her mother’s body.

  Watching.

  Enjoying.

  Her fists clenched.

  Her heartbeat thundered in her ears.

  “Kaede?”

  Michibiki asked gently.

  The sound snapped her back.

  Kaede’s eyes sharpened, jaw tightening as she stepped forward.

  Without warning, she drew back her fist and punched the wall.

  The impact exploded through the chamber.

  Stone cracked outward in a web of fractures before collapsing entirely, chunks of the wall crashing to the floor in a cloud of dust. The symbol was gone, obliterated.

  Kaede rolled her shoulder, shaking out her hand as if she’d just swatted an insect.

  “I’m fine,”

  She said flatly, forcing a grin.

  “Just remembered something from a while back. Let’s move.”

  Yukio stared at the ruined wall, then at her.

  “…That was, like, years of ancient history,”

  He said, reaching out and flicking her forehead lightly.

  “Now it’s gone.”

  Kaede shoved him forward roughly.

  “Who cares? We’ll blame it on the monsters.”

  Michibiki didn’t push the issue, but her eyes lingered on Kaede’s back longer than usual.

  They pressed on.

  The corridors narrowed again, descending deeper into the ruin. The air grew heavier with every step, pressing against Yukio’s senses like an invisible tide.

  Then the Threads screamed.

  Yukio staggered.

  His knees hit the stone hard enough to rattle his teeth.

  “Yukio!”

  Kaede barked, spinning around.

  The world blurred. His vision flooded with red as pain tore through his skull like lightning. He clutched his head, gasping as something warm slid down his face.

  “…What the hell…”

  He choked.

  Blood dripped from his eyes.

  Inside his mind, chaos erupted.

  The Wheel spun wildly, faster than he’d ever seen, its golden surface burning red as probability collapsed into something hostile and wrong. The Threads twisted and snapped, pulling in every direction at once.

  Vaelora’s voice echoed sharply.

  “Yuki! Don't fight it! Don’t pull back!”

  “I’m not…!”

  Yukio groaned, barely conscious.

  Michibiki was already beside him, forcing a potion to his lips.

  “Drink.”

  He swallowed reflexively.

  Another potion followed immediately.

  Then another.

  Kaede shoved past Michibiki, holding out two more.

  “Again.”

  Yukio coughed, choking down bottle after bottle, his body barely keeping up.

  “…How many was that?”

  He slurred weakly.

  “Two,”

  Michibiki replied.

  “Three,”

  Kaede added, already uncorking another.

  “…Seven,”

  Michibiki muttered under her breath as the last one went down.

  Yukio finally managed to stand, legs trembling beneath him. The bleeding stopped, but the pressure in his skull refused to fade.

  Michibiki steadied him, her expression tight.

  “This isn’t safe. Whatever is down here is actively rejecting your abilities.”

  Yukio forced a shaky smile.

  “Guess I’m not welcome.”

  Kaede glanced down the corridor ahead, fists clenched.

  “…Yeah. Let’s head back.”

  They turned.

  And the air shifted.

  Four figures stepped out of the darkness ahead of them, their movements silent and unnatural.

  They were tall. Broad-shouldered.

  Encased in pitch-black armor etched with the same crescent moon crest, ash circling its hollow center.

  Kaede’s breath froze in her throat.

  The one in the center tilted its head slightly.

  “Humans,”

  It said, voice calm, hollow, and wrong.

  It raised one armored hand.

  “Kill them.”

  The three flanking figures moved instantly.

  Kaede surged forward on instinct, wind flaring beneath her feet but she was too slow.

  Their movements were precise. Controlled. Not wild like the corrupted beasts.

  One slipped past her swing effortlessly, blade flashing.

  Michibiki stepped forward, hands glowing brilliantly.

  “Stay back,”

  She commanded.

  Light exploded outward.

  She intercepted all three demons in a blur of motion, her spells landing in rapid succession, barriers forming mid-air, blasts of condensed light striking with surgical precision.

  Kaede watched in stunned disbelief as Michibiki forced them back, each attack calculated, each movement flawless.

  Yukio’s legs buckled again.

  Michibiki glanced over her shoulder.

  “Now!”

  She raised both hands, mana surging violently.

  “Dual Cast.”

  A spell circle flared beneath her feet.

  “Fire magic: sizzling combustion.”

  A second circle overlapped it instantly.

  “Spatial magic: Teleport.”

  The blast detonated, light and force tearing through the chamber.

  The central demon raised one hand and slapped the explosion aside as if swatting dust.

  But it was already too late.

  The world twisted.

  They reappeared violently at the ruin’s entrance, tumbling onto stone just outside the sealed gates.

  Alarms rang out instantly.

  Guards rushed toward them, weapons drawn, shouting orders.

  Kaede scrambled to her feet, spinning around.

  “…They followed?”

  Michibiki shook her head, breathing hard.

  “No. The spell was clean.”

  Yukio leaned heavily against the wall, chest heaving.

  “…That was too close.”

  The gates slammed shut behind them, sealing the ruins once more.

  High above, unseen.

  Four figures stood in the darkness.

  Waiting.

  Deep within the ruins, silence reclaimed the shattered chamber.

  Dust settled slowly where the teleportation blast had torn the air apart. The residual mana crackled faintly, then faded, leaving only the low, unnatural hum that pulsed through the stone like a heartbeat.

  Three armored figures emerged from the shadows, kneeling immediately before the fourth.

  “Sir,”

  One of them said, voice sharp and disciplined.

  “Should we pursue them?”

  The demon they addressed stood alone near the broken wall where the humans had vanished. Taller than the others, his armor bore deeper engravings, the crescent moon etched with thicker bands of ash. His presence weighed on the air itself, bending it subtly.

  He didn’t turn around at first.

  “No,”

  He replied calmly.

  The soldiers stiffened.

  The demon finally looked down the corridor leading toward the surface, crimson light glowing faintly from the slits of his helm.

  “Don’t waste your energy chasing them,”

  He continued.

  “They served their purpose.”

  One of the soldiers hesitated.

  “But sir.”

  “I said no.”

  The word carried enough pressure to make the stone beneath their feet tremble.

  The soldier lowered his head immediately.

  “Understood.”

  The demon lifted one clawed hand, gesturing toward the deeper passage.

  “Prepare the waypoint,”

  He ordered.

  “The foundation is unstable. We’ll anchor it here.”

  The three demons rose in unison and moved without another word, their footsteps echoing sharply as they disappeared down the corridor, already beginning the preparations.

  The chamber grew quiet again.

  The fourth demon remained where he was, staring at the fractured wall where Kaede’s fist had shattered ancient stone.

  A low laugh echoed from beneath his helm.

  “A Fate-breaker…”

  He mused, voice dripping with amusement.

  “And one of them doesn’t even realize what she’s seen.”

  He turned slowly, his gaze drifting deeper into the ruins, toward the heart of the corruption.

  “About time things got interesting,”

  He said, almost to himself.

  “I was growing bored.”

  With measured steps, he followed after his soldiers, his laughter lingering in the shadows long after he vanished.

  And far above, the city slept unaware of what had begun to move beneath its golden pillars.
