The fire had burned down to embers, leaving only the faint pulse of mana crystals to light the hollow. Kael rose slowly, joints stiff but mind sharp, and slung his pack over one shoulder—the weight of supplies and spell components grounding him.

  Above, Rimuru drifted in a soft blue haze, while Nyaro stretched with a low rumble, his golden coat rippling like liquid light in the dim cavern.

  The break was over. It was time to go deeper.

  Kael tightened the strap on his right glove and glanced once at the cracked ceiling above, where a thin sliver of night sky had been visible hours ago. Now, only the crushing weight of the dungeon pressed down.

  He turned toward the stairwell cut into the rock—spiraling downward like the throat of some ancient beast.

  “Ready?” Kael asked, keeping his voice low.

  Rimuru flared a bright green—Ready.

  Nyaro shook out his fur once, then moved to the front without hesitation.

  Kael’s smile was faint, but there was steel behind it. With the slime at his shoulder and the panther in the lead, he stepped into the stairwell.

  The descent into Floor 2 began.

  The air shifted the moment they left the landing. Heat pressed in from all sides, thick and uneven, carrying the faint taste of ash. Mana currents twisted unpredictably through the stone, bending the passage into odd angles that sent their echoes skittering in the wrong direction.

  Every footstep seemed to last too long.

  Kael flexed his fingers, drawing a thread of fire into his palm. He shaped it carefully, keeping the heat caged until it settled into a controlled glow.

  One by one, small orbs of flame winked into being around him, drifting like patient fireflies. Their light clung stubbornly to the walls instead of vanishing into the dark.

  

  Kael let out a slow breath. “Feels like the dungeon’s watching closer now.”

  

  Nyaro padded ahead, steps soundless on the jagged floor. Rimuru drifted just above Kael’s shoulder, her glow flickering between blue and yellow like she couldn’t decide between caution and excitement.

  Every so often, the carved walls shivered and exhaled faint gusts of superheated air, as if the whole place were breathing.

  Kael’s eyes narrowed. “Yeah… it’s breathing.”

  Rimuru’s glow dimmed to a wary orange. Nyaro’s ears flicked back, catching something deeper in the dark.

  The passage tightened around them, the floor breaking in places into narrow cracks where molten mana pulsed far below like veins of buried fire.

  They stopped at a ledge where the heat thickened, rolling toward them in slow, heavy waves. Beyond it, the corridor opened into a vast cavern where shadows shifted without a source.

  Rimuru dimmed her light to a pale shimmer. Nyaro sank low to the ground, tail sweeping in tight, deliberate arcs.

  Kael drew a measured breath and kindled a single flame in his hand—small, steady, ready.

  Beyond the threshold, something shifted at the edge of the light. It moved too quickly for stone, too deliberately for debris.

  His grip tightened. Whatever waited ahead, the real descent was about to begin.

  The cavern stretched wide, but Kael’s focus locked on the flickers sliding just beyond Rimuru’s glow. At first they seemed like drifting smoke, curling across the stone.

  Then the haze twisted, pulling into lean, skeletal shapes.

  One lunged—fast as a whip of fire.

  Kael barely shifted aside as white-hot eyes and clawed hands streaked past him, leaving scorched air in their wake.

  Fire Wraiths.

  Instinct took over. Kael caught the heat building in his chest and pulled it into his palm, compressing it until it glowed white-orange. He slammed the orb into the wraith’s chest.

  The creature screamed—a high, tearing sound like burning reeds—before folding in on itself and scattering into embers.

  Dozens more slid from cracks in the floor, their unstable bodies flickering between collapse and form.

  Kael dropped into a low stance.

  

  Nyaro lunged first, a streak of gold through the smoke. His claws, charged with Kael’s residual mana, ripped through a wraith’s chest, scattering it in an instant.

  Rimuru hardened her form into a spiked shield, smashing two more aside with wet, bone-jarring impacts.

  Kael reached deeper, pulling his flame into thin, whip-like strands. They lashed out with surgical precision, spearing unstable cores one after another.

  Each wraith collapsed instantly, ash scattering at his feet. The survivors circled warily, their motions jerky with agitation.

  Kael pressed the advantage, weaving between jagged outcroppings to break their line. He drew them out one by one, striking fast before they could swarm.

  Rimuru mirrored his movements, knocking enemies off balance with quick bursts.

  Nyaro stalked the edges, darting in for sudden, decisive kills.

  The fight wore on, favoring control over power.

  Sweat traced a line down Kael’s temple as the last wraith let out a piercing screech and unraveled into ash. Silence rushed in, broken only by the faint hiss of cooling stone.

  

  Kael crouched beside the nearest pile of ash, spotting a faint ember floating where the creature’s chest had been. Barely the size of a marble, it pulsed with residual heat.

  He plucked it from the air, feeling its warmth settle into his palm. “First real loot,” he murmured, slipping it into his pack.

  He glanced at Rimuru’s triumphant green glow and Nyaro’s steady, waiting gaze.

  “Good work,” Kael said, his voice carrying in the still cavern.

  But there was no time to linger—the dungeon wouldn’t stay quiet for long.

  He turned toward the shadow-soaked tunnel ahead, its narrow mouth drawing them deeper. “Let’s keep moving.”

  Together, they stepped into the tightening dark.

  The walls closed in as they entered Floor 3, jagged stone jutting like broken teeth from floor and ceiling. The air thickened, clinging to Kael’s skin with a faint smell of scorched minerals.

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

  Every step carried a low tremor through the ground, and the faint light from his flame orbs seemed to vanish too quickly, as if the stone was drinking it in.

  Collapsed bridges and vents of glowing magma broke the path ahead, while dead-end tunnels shimmered faintly with illusion magic, bait for the unwary.

  

  Kael gave a short nod, motioning Rimuru closer while Nyaro advanced in slow, deliberate steps.

  Half an hour later, the tunnel spilled them onto the edge of a broken bridge spanning a twenty-meter chasm. Below, a river of molten mana flowed in lazy waves, its surface popping in bursts of gold and crimson.

  The bridge’s center was gone—five meters of empty air between the crumbling halves, too far to jump, too unstable to rebuild.

  Kael crouched at the edge, studying the gap. He drew the fire in tight, shaping it into something that could hold.

  Heat shimmered in the air as a disk of hardened flame formed—a floating platform just wide enough to stand on. It wobbled in place, radiating dry heat.

  

  Nyaro crouched low, muscles tensing.

  “Go,” Kael ordered.

  The panther sprang, paws touching the platform for barely a heartbeat before landing clean on the far side.

  Rimuru zipped after him, weightless.

  Kael followed last, boots hitting the flame disk just as it began to sag, and leapt clear.

  Behind him, the platform crumbled into sparks over the molten river.

  He straightened, breathing hard, and let a faint grin slip. “Not bad for my first flame bridge.”

  Rimuru projected a shaky thumbs-up.

  Nyaro flicked his tail, already prowling toward the next tunnel.

  Kael tightened his grip on his pack straps and followed, leaving the cooling glow behind him.

  The tunnel funneled them into an even narrower throat of stone. Kael’s flame orbs dimmed, not from lack of mana but because the walls seemed to drink in the light.

  Every footstep echoed too long, as if the dungeon were memorizing their presence.

  He raised a hand, signaling Rimuru and Nyaro to stay close.

  

  Kael’s eyes swept the rough walls. “Define anomaly.”

  

  His pulse quickened.

  True artifacts, buried deep where no casual explorer would ever reach.

  Faint outlines shimmered under Rimuru’s light—rings of runes buried beneath mineral crust, each with a narrow slit at its center, like a weapon sealed in stone.

  Kael asked.

  

  Kael clicked his tongue.

  He marked the wall a few paces back with Emberleaf’s spiraling flame sigil, a warning for whoever came next.

  Rimuru drifted closer, extending a thin pseudopod toward one of the rune rings.

  The air rippled as black threads of corrupted mana bled outward, snaking toward her.

  “Rimuru—!” Kael shouted.

  But she was already absorbing it, Predator flaring to life. The taint vanished into her body, neutralized before any trap could trigger.

  She wobbled once, then steadied, glowing a confident gold.

  Kael let out the breath he’d been holding. “You reckless slime,” he muttered, half a laugh in his voice.

  Rimuru projected a tiny doodle of him holding a 10/10 scorecard.

  “Yeah, fine—ten points,” he said, shaking his head. “Just give me warning next time.”

  Nyaro’s ears flicked toward the dark ahead, urging them on.

  They marked two more artifact sites but kept their distance, the air feeling sharper each time.

  The dungeon was starting to wake.

  The tunnel spilled abruptly into a wide, circular chamber etched from floor to ceiling in spiraling rune work. Static prickled across Kael’s skin as mana pulsed through the air in invisible tides.

  He took one cautious step inside—

  The runes flared crimson and orange, lines racing outward in jagged webs.

  The walls split with soundless force.

  And a tide of Fire Wraiths poured in from every direction.

  Kael snapped up a barrier of compressed flame, catching the first claw swipe before it could tear into him.

  

  Kael hissed between his teeth.

  He cut down two wraiths with a whip of fire and shouted, “Rimuru, the runes are feeding this. Show me the pattern.”

  Rimuru shot upward, her body flattening into a shimmering plane of condensed mana. The chamber’s runes reflected across her surface, lines and nodes lighting up as the structure revealed itself in real time.

  

  Kael ducked another swipe, slammed his palm onto the matching floor glyph, and felt the outer runes flicker weaker.

  One step down.

  More wraiths surged in, each death ending in a burst of volatile mana shards. Kael weaved through them, blasts sparking off his barrier.

  Rimuru’s projection shifted, three glyphs flaring at once.

  

  Kael sprinted for the first, slamming it with a surge of flame-wrapped mana.

  Rimuru hurled herself into the second with a wet, decisive smack.

  The chamber shook, outer runes dimming to a strained flicker.

  Two wraiths collided midair, detonating in a chain of explosions that rattled the walls.

  

  Kael’s gaze swept the room. One glyph burned high on the far wall. The other lay buried beneath cracked rubble.

  “Nyaro!” Kael shouted, pointing.

  The panther bolted, bounding up a fallen column and launching off the wall. His claws struck the high glyph dead-center, shattering it in a flare of light.

  Kael funneled flame into his legs and sprinted for the buried seal. He dove, slammed both palms into the fractured glyph, and forced raw mana through the stone.

  The rune screamed, then burst apart, taking the last of the chamber’s light with it.

  The runes along the walls and floor guttered out, leaving only drifting ash where the last wraiths had fallen.

  Silence pressed in, heavy and absolute.

  Rimuru floated down, projecting a shaky banner overhead: MISSION COMPLETE.

  Kael laughed once under his breath, more relief than humor. “Nice work.”

  Nyaro padded over, breathing hard but unscathed, as stone ground open nearby, revealing a stairwell descending deeper.

  They descended, the steps vibrating faintly beneath their boots and paws—not from instability, but from the hum of raw mana below. Sparks of wild magic snapped along the walls, painting the tunnel in shifting colors.

  

  The stairwell opened into chaos.

  Bolts of unaligned magic ripped through the passage, carving scars into the stone. Heat columns warped the air, and pockets of crushing gravity spun like invisible whirlpools.

  Kael raised a Flame Shield to block an incoming bolt, only for it to crack instantly under the pressure, backlash searing up his arms.

  Pain jolted through his mana flow, sharp and tearing, forcing him back a step.

  

  Another wild bolt slammed into the floor, throwing Kael off balance. His mana spiked erratically—seconds from rupture—

  Then Rimuru blurred forward, wrapping around him like a living shield.

  Predator flared, pulling the unstable energy from his body until the pain ebbed and his breathing steadied.

  

  Kael sagged to one knee, forcing a shaky laugh. “Saved my ass again, huh?”

  Rimuru pulsed gold and projected a tiny slime in a cape.

  Nyaro prowled nearby, intercepting stray bolts before they could come too close.

  Kael adjusted his stance, jaw set. From here on, it would take control, not output.

  They moved through the storm in tight formation. Kael ducked and weaved between arcs. Nyaro’s instincts pulled them clear of sudden bursts. Rimuru absorbed stray currents before they could bite.

  Each step forward felt like pushing against a river in flood.

  By the time they reached calmer stone, Kael’s hoodie was singed, his gloves scorched, and his mana reserves running thin, but they were still standing.

  He leaned against a cracked pillar, chest rising and falling in slow, measured breaths.

  Rimuru settled warm and solid on his shoulder.

  Nyaro sat nearby, tail flicking in quiet vigilance.

  Ahead, another spiral stair waited, vanishing into shadow.

  They didn’t hesitate.

  Survival alone wasn’t the goal anymore.

  The stair from Floor Four was short, almost abrupt, as if carved in haste. Kael climbed it with slow, certain steps, the storm’s chaos burned down into a hard edge of focus.

  They had made it through. Adapted. And now every instinct warned him they weren’t alone.

  The air changed first. Mana pressed heavy and condensed, patient, waiting just ahead.

  They slipped into a half-collapsed corridor, stone split by blackened vines and scorched fractures. At the far end, before the next stairwell, stood the Sentinel. A towering mass of cracked iron and stone.

  Fire glimmered faintly in the gaps of its armor. Its head hung low, almost at rest, but the slow, deliberate pulse of mana beneath the shell told a different story.

  

  Kael studied the fractures in its armor. There were weak points, but not ones he could afford to test after the storm.

  This wasn’t a fight to win.

  It was one to avoid.

  He mapped the rubble and shadows, then murmured, “We slip past. Quiet.”

  Rimuru dimmed to a faint green.

  Nyaro sank lower, muscles coiled, eyes never leaving the Sentinel.

  Kael led them forward, threading between fallen columns and broken stone. Every step sounded too loud in his ears.

  A loose pebble skittered across the floor.

  The Sentinel’s head twitched.

  Then stilled.

  They eased past the edge of its shadow and onto the stair without a sound, not stopping until the corridor curved away and the pressure finally eased.

  Kael leaned against a cracked wall and let his pack slide to the ground.

  Rimuru settled into his lap, her colors shifting in slow, tired waves.

  Nyaro dropped beside them with a quiet huff, tail tapping once against the stone.

  The silence here felt different. Heavy, but not threatening.

  Kael tipped his head back. Through a jagged break in the ceiling, stars glimmered faintly in the dark. Real or illusion, it didn’t matter. It was enough.

  A reminder that the world above was still there. Waiting.

  They had endured four brutal floors and kept moving.

  Kael let the sight steady him, then closed his eyes. “Almost there,” he murmured.

  The words faded into stone, heard only by Rimuru’s soft pulse, Nyaro’s steady breathing, and perhaps the dungeon itself.

  Whatever waited below, they would face it together.

  And as long as the three of them kept moving, Emberdeep would not have the last word.
