The moment Ryuji's fist pierced the core, the entire chamber reacted.
Not gradually.
Not subtly.
Violently.
The impact didn't just crack the core—it ruptured it completely. The surface shattered inward and outward at the same time, jagged fractures spreading across its shifting mass like spiderwebs racing across breaking glass. Unstable energy burst free in violent pulses, the violet glow that had once pulsed with steady, ominous rhythm now flaring erratically, flashing in blinding intervals that distorted the space around it and made everything look like a nightmare caught in a broken strobe light.
For a single heartbeat, everything froze in stunned silence.
Then the dungeon screamed.
It wasn't a sound you heard with your ears.
It was a sensation—a pressure that slammed into their minds all at once, sharp and overwhelming, like something vast and ancient had just realized it was dying and wanted everyone to feel its pain.
Elrica staggered hard, her knees buckling as she clutched her head with both hands. "I— I can't—! It's too loud inside my head!"
Kaelina caught her instantly, strong arms pulling her back before she could collapse completely. "Stay with me," she said firmly, her voice cutting through the chaos like a lifeline. "Focus on me. My voice. Right now."
Darek braced himself against the wildly shifting ground, his boots grinding against the surface as fresh cracks spread beneath him like hungry mouths opening up. "That did it!" he shouted over the rumbling. "Tell me that did it! Please tell me we're not about to get buried alive for nothing!"
"Oh, it definitely did it!" Lumi snapped, her voice pitched higher than usual as she hovered frantically near Ryuji. "You just broke the core of a corrupted Abyss dungeon! Do you know what happens next?! Do you?!"
Ryuji pulled his arm free from the collapsing mass, shaking off fragments of dark energy that clung briefly to his skin like sticky tar before dissipating into nothing. His grin hadn't disappeared—it had sharpened into something wild and satisfied.
"…I'm guessing it's not good."
"The whole place collapses, you idiot!" Lumi shrieked.
"Yeah," he said calmly, stepping back just as another violent pulse rippled through the chamber. "Figured as much."
---
The core convulsed wildly.
The fractures deepened rapidly, spreading across its surface like lightning cracks in glass. Dark energy leaked out in violent surges, spilling into the air as unstable waves that distorted everything they touched—making the air ripple, the pillars bend, and reality itself feel like it was glitching. The warped pillars around them began to warp even further, bending and twisting as if pulled by an invisible, furious force.
Then the ground gave way.
Not entirely.
But enough to make hearts stop.
Chunks of stone—or whatever twisted parody of stone this dungeon used—broke free and sank into the darkness below with sickening finality. The circular platform that had risen earlier began to collapse inward, dragging everything toward its hungry center like a drain sucking down the whole world.
Kaelina's voice cut through the growing pandemonium again, sharp and commanding. "We retreat! Now!"
Darek didn't argue for once. "Finally, something I agree with! Let's get the hell out!"
Elrica nodded weakly, still recovering as she forced herself upright on shaky legs. "The entrance—do we go back the same way?!"
Lumi shook her head rapidly, wings buzzing in panic. "No! The structure's unstable! The path we came through might already be gone!"
Ryuji glanced at her, still moving with that infuriating calm. "Then we make a new one."
"That's not how—"
Another violent tremor shook the chamber, cutting her off as a massive section of the ceiling cracked open with a deafening groan. Debris rained down—not falling cleanly, but dissolving midair as the unstable energy consumed it like acid.
"…Okay," she amended quickly, eyes wide. "That might actually be how!"
---
The system flickered to life in front of Ryuji's eyes.
Then—
[Warning]
Dungeon Core Integrity: 12%
Structural Collapse Imminent
Evacuation Recommended
---
Ryuji glanced at the notification and snorted lightly, a short laugh escaping despite everything. "Well, at least it's polite about it."
Lumi stared at him like he'd grown a second head. "That's your takeaway?!"
"It said please."
"It did NOT say please!"
---
The chamber lurched again.
This time harder, like the dungeon was throwing a full-blown tantrum.
The ground beneath their feet tilted slightly as the entire structure shifted downward, the circular platform sinking faster now, pulling them toward oblivion. The core continued to collapse in on itself, its surface breaking apart into fragments that dissolved into raw, screaming energy before they could even hit the ground.
Kaelina adjusted instantly, pulling Elrica along as she moved toward the edge of the chamber with perfect balance. "We need higher ground," she said, voice steady even now. "If the center collapses, everything around it will follow like dominoes."
Darek nodded, already moving with heavy, powerful strides. "Got it! Stay close!"
Ryuji didn't follow immediately.
His gaze remained fixed on the core.
On something within it that refused to die with the rest.
"…Hold up," he muttered.
Lumi froze mid-hover. "What do you mean 'hold up'?! We don't have time for 'hold up'!"
"There's something in there."
"There's a collapsing Abyss core in there!"
"No," he said, narrowing his eyes with that familiar thrill. "Something else."
---
The collapsing mass shifted chaotically.
For a brief moment—
The chaotic energy parted like curtains in a storm.
And something became visible within the core.
A shard.
Small compared to the rest of the monstrous sphere.
But different.
It didn't flicker.
Didn't destabilize.
It glowed steadily, a deep, concentrated violet unlike the erratic, dying light surrounding it—calm, focused, almost calling to him.
Ryuji's grin returned full force.
"…Yeah," he said, eyes lighting up. "That's loot."
Lumi grabbed his collar instantly with both tiny hands, yanking desperately. "NO. ABSOLUTELY NOT. WE ARE LEAVING RIGHT NOW."
He didn't move an inch.
"Let go."
"I will drag you out of here myself!"
"Too slow."
"TRY ME!"
---
The chamber shook again.
Harder than ever.
The ground beneath them cracked further, entire pieces breaking away and vanishing into the void below with terrifying speed.
Kaelina turned sharply, eyes wide with urgency. "Ryuji! Move!"
Darek added his deep roar, "Now's not the time for sightseeing, you crazy bastard!"
Elrica looked utterly panicked. "Please don't do anything stupid!"
Ryuji glanced at them for half a second.
Then back at the core.
"…Define stupid."
Lumi screamed at the top of her lungs. "RYUJI—!"
---
He moved.
Fast.
Before anyone could stop him.
He dashed forward, weaving through the collapsing terrain with precise, efficient steps that looked almost casual. The ground broke beneath him twice, chunks vanishing into nothing, but he adjusted instantly, using the momentum to push off unstable surfaces and close the distance like it was nothing.
The core pulsed violently as he approached, reacting to his presence with pure rage.
The energy lashed outward in deadly whips—
He slipped past them with inches to spare.
The pressure intensified, trying to crush him—
He pushed through it, grinning the whole way.
"…Come on," he muttered under his breath. "Don't be shy now."
The shard flickered once.
As if responding.
---
The system surged in warning.
[Unknown Artifact Detected]
[Energy Signature: Unregistered]
[Warning: Interaction Risk High]
---
Ryuji didn't slow down for a second.
"…Yeah, yeah," he muttered. "Worth it. Totally worth it."
Lumi's voice echoed behind him, furious and terrified. "IF YOU DIE, I'M NOT REVIVING YOU AGAIN!"
"Good to know!"
---
He reached it.
For a split second, the chaos around the shard calmed completely—as if the space itself recognized his presence and paused in reluctant respect.
Ryuji didn't hesitate.
He grabbed it.
---
The reaction was immediate and overwhelming.
A surge of energy shot through his arm, sharper than anything he had felt before. Not exactly pain—but something deeper, like his body was being forced to process something ancient and powerful it didn't fully understand. His vision flickered wildly. The chamber distorted around him.
For a moment—
He saw something else.
Not the dungeon.
Not the core.
But something vast.
Watching.
Then—
It was gone, leaving only the shard pulsing in his grip.
---
"RYUJI!"
Kaelina's voice snapped him back to reality.
The chamber collapsed further in a final, furious surge.
The core's remaining structure shattered completely, releasing one last, violent pulse that cracked the ground beneath him entirely.
"…Yeah," he muttered, gripping the shard tightly as he turned. "Time to go. Right now."
---
He turned.
And ran.
---
The return wasn't clean. It was pure chaos.
The path behind them had already begun to collapse, sections of the floor missing entirely, replaced by empty, hungry void. The pillars were falling now, their warped forms breaking apart as the dungeon structure failed in spectacular fashion.
Kaelina moved first, leading the desperate path with flawless precision despite the instability. Darek stayed close, clearing debris when needed with powerful swings, while Elrica struggled to keep up, her mana nearly depleted and legs burning.
Lumi hovered beside Ryuji the whole way, still furious. "You are unbelievable! You just ran into a collapsing core for a random item!"
"It wasn't random."
"You don't know what it is!"
"Exactly."
"That's worse!"
---
The system flickered again.
[Item Acquired: ???]
[Classification: Unknown Artifact]
[Status: Unanalyzed]
---
Ryuji glanced at it briefly while sprinting.
Then smirked.
"See? Worth it."
Lumi looked like she might actually explode from sheer rage and terror.
---
The final stretch came into view.
The entrance.
Or what remained of it.
The doorway they had come through was still there—but unstable, flickering at the edges like it might collapse at any second and trap them forever.
Kaelina didn't slow. "Move! Faster!"
Darek grabbed Elrica, pulling her forward to increase their speed without losing her.
Ryuji followed right behind them, heart pounding with thrill.
The ground gave way beneath him one last time—
He jumped.
Cleared the gap with room to spare.
And crossed the threshold.
---
The moment they exited—
The dungeon collapsed.
---
The entrance sealed behind them with a violent surge of energy, the entire structure imploding inward as the corrupted core fully disintegrated. The ground outside trembled once, twice—then settled into sudden, blessed stillness.
Silence followed.
Real silence.
For the first time since they had entered this nightmare.
---
Darek dropped to one knee, exhaling heavily like he'd run a marathon. "…Yeah. I'm done for today. Completely done."
Elrica sat down right where she stood, breathing hard and shaking. "I… I thought we were going to die… Actually die this time…"
Kaelina remained standing, though her shoulders lowered slightly as the tension finally released from her body. "…We survived," she said quietly.
Then her gaze shifted.
To Ryuji.
"…Barely."
Ryuji rolled his shoulders casually, completely relaxed like he'd just finished a fun training session.
"…That was fun."
Lumi stared at him in exhausted disbelief.
"…You need help. Serious, professional help."
"Probably."
---
The system flickered one last time.
[Dungeon Cleared]
[Bonus Objectives Completed]
[Rewards Calculating…]
---
Ryuji's grin widened into pure satisfaction.
"…Now that's what I'm talking about."
But in his hand—
The shard pulsed once.
Quietly.
Secretly.
And far deeper than anyone else could feel—
Something responded.
