Dust lingered faintly in the stale air. The walls were smooth in places, jagged in others, like something unfinished. Or something constantly rewriting itself.
"Is it just me or does this feel a little too peaceful?" Haruki's voice echoed directly into the minds of the three of them, her tone edged with suspicion rather than relief.
Peace in a place like this was rarely a gift. It was usually a warning.
"Well, it's not a bad thing. If this happens till we get out, it'd be great." Hana replied, trying to sound optimistic. But even she kept her senses stretched thin, eyes scanning corners and shadows.
"Only if that's the case. But if they're actually going up, we'd have to deal with a lot of trouble." Haruto added quietly. His gaze drifted along the walls, tracking every crack, every unnatural line in the stone. He wasn't relaxed. Not even close.
"What makes you think they're going up?" Hana asked.
"I mean, I don't know for sure but... it's a possibility, isn't it?" he responded. His voice was calm, but his thoughts were not. If the upper floors were being cleared faster than expected, it meant something was accelerating the labyrinth's behavior. And that was never good.
They continued forward, the silence thick and strangely intact.
As they walked ahead, something surfaced in Haruto's memory.
"Oh, yeah. There's one of those big doors here. You said they're traps, right?" He glanced at Haruna.
She answered immediately, though there was a faint tremor in her voice. "Y-yes. But they could still be treasure chambers. They're usually the most guarded, so either way they're not good news." Her brows furrowed as another thought surfaced. "But... I never saw it when I came down. Maybe because I was too occupied trying to escape those monsters?"
Her memory of that descent was still sharp. Panic. Blood. The sound of things chasing her in the dark.
"Ah, look. There it is." Haruto pointed ahead.
Haruna followed his gesture.
And froze.
At first glance, it was just a wall. A broad, seamless stretch of smooth stone, unnaturally perfect compared to the rugged surroundings. But at its center stood a door.
Not just large.
Monumental.
It rose like the gates of a fallen empire. Taller than any castle entrance they had seen. Ancient runes coiled across its surface in layered patterns, glowing faintly under the dim ambient light. Symbols overlapped and intertwined like veins beneath skin, forming a language that felt older than memory.
It did not merely exist in the chamber.
It dominated it.
Yet the size wasn't what stole Haruna's breath.
"This is... This is where I came from!" she exclaimed, her voice breaking as she hurried toward it. Her steps quickened, almost frantic. "Where did this come from?"
Haruto's expression tightened. "What do you mean? This isn't one of those treasure chambers?"
"N-no." She shook her head, eyes scanning the wall desperately. "This is where the tunnel was supposed to be. I remember clearly. The tunnel was right here. On this smooth wall..."
Her fingers brushed the stone as if she could peel the illusion away.
And then it hit her.
"No... It can't be happening this quickly, can it?"
"Happening what?" Hana asked, stepping closer.
Haruna turned toward them, and the color had drained from her face.
"The labyrinth is starting to shift. It seems like we were wrong about its estimated time. It already started." She swallowed. "That means..."
She couldn't finish.
"That means... they've taken out most of the labyrinth's monsters?" Haruto completed the thought quietly.
Haruna only nodded.
The implication settled over them like a weight pressing against their ribs.
"We have to find the right way up again. Or..." Her voice trailed off. She didn't need to say the rest. Or they'd be swallowed by shifting passages and sealed inside like insects in amber.
This novel's true home is a different platform. Support the author by finding it there.
Haruto stepped toward the towering door. Its surface hummed faintly, barely perceptible. He placed a palm against the wood. It was colder than expected.
"Could it still be that the tunnel is behind this and the door is the only thing that got generated yet? We're still in here after all." His voice carried a fragile hope. Or maybe it was logic trying to impose order on chaos.
"I... don't know." Haruna's uncertainty was honest. "I only know the labyrinth can shift. Even that I heard from my teacher once."
Haruto hesitated.
His fingers curled slightly against the door's surface.
"I... probably shouldn't touch this, should I?"
"Man, just do it already!" Haruki snapped inside their minds, impatience flaring like sparks. "You're overthinking it."
"You say that but I don't see you doing anything."
"I don't have arms!" she shot back.
"Exactly." He didn't even turn around. "So let us handle this, okay?"
"Haruna, could you just do it already? He's just dumb." Haruki muttered irritably.
Haruna looked at Haruto instead, silently asking.
He exhaled slowly. The air felt heavier now.
"Okay, fine. I'll do it."
Without further hesitation, he stepped fully in front of the massive doors and placed both hands against them. The runes beneath his palms pulsed faintly, like something reacting to his touch.
He pushed.
For a split second, nothing happened.
Then—
The space around them warped.
Not gradually.
Not with warning.
The world folded inward like fabric caught in a vortex. Stone stretched. Air twisted. The chamber distorted violently, as if reality had been grabbed and wrung out by invisible hands.
Sound collapsed.
Light fractured.
The ground vanished beneath their feet.
In a blink, they were swallowed by nothingness.
Behind them, the monumental door began to fade, dissolving into particles like dust scattered by an unseen wind. The ancient runes dimmed, the structure unraveling as if it had never truly existed.
And where it once stood—
The original tunnel revealed itself once more.
Silent.
Waiting.
As if the door had only been a lie written over it.

…
As the cold, systematic voice declared the deconstruction of the great labyrinth, the earth itself answered.
It trembled.
Not violently at first. Just a low shudder that rolled through stone like a suppressed groan. Then the trembling deepened, spreading across walls, ceilings, foundations. The very geometry of the dungeon seemed to falter, as if whatever force had held it together was quietly withdrawing its hand.
Crystals lining the walls flickered and dimmed.
Moss shriveled into ash.
Stalagmites fractured down their length with dry, cracking sighs.
Soon, the labyrinth began collapsing inward. Not exploding. Not breaking outward.
Folding.
Every stone, every vein of crystal, every creeping herb and lurking monster was seized by an invisible mechanism and reduced to raw matter. It was not destruction born of chaos.
It was systematic erasure.
All that the Chaos Maw had been was deconstructed under the unyielding protocol established by Lord Charybdis himself.
A god’s final instruction.
And because Haruna and the others still counted as challengers of the labyrinth, that same protocol extended its impartial mercy to them. It granted them a final path, a fabricated space. A pseudo dungeon.
A temporary sanctuary.
A chance to escape before the original structure ceased to exist.
But then—
From the smallest cracks in the collapsing stone, something else answered.
A faint drop of blood slid free.
It did not fall heavily. It did not splatter.
It descended with deliberate slowness, like the first stroke on a blank canvas.
When it touched the ground, it did not disperse.
It expanded.
In the span of seconds, that single droplet multiplied tenfold. Then again. Then again. It spread across the stone in branching veins, thickening, darkening, swallowing cracks whole.
And then it surged.
From every fissure in the unraveling labyrinth, blood began to gush. Not as a chaotic flood, but as a ravenous tide moving with purpose. It poured from the ceilings, seeped from fractured pillars, erupted from beneath shattered crystal beds.
It did not merely cover the ruins.
It devoured them.
Stone dissolved into crimson currents. Monsters caught mid-disintegration were swallowed before the system could finish reducing them. Moss, dust, shattered gates, ancient runes, everything that had once composed the Chaos Maw was engulfed in gluttonous blood.
The labyrinth was not collapsing anymore.
It was being consumed.
Within moments, the great dungeon became an ocean of dark red, churning and thick, digesting its contents with terrifying efficiency. No debris floated. No fragments remained.
Only blood.
And silence.
Minutes passed.
Then the ocean began to recede.
The vast sea of crimson shuddered as if responding to an unseen call. Its surface trembled, then folded inward. The blood drew itself together from every direction, flowing back toward a single point with unnatural urgency.
Walls of liquid collapsed inward.
Streams converged.
Everything condensed.
In mere seconds, the entire mass compressed into a single, compact orb no larger than a fist.
It hovered briefly in the air, glistening.
Then fell.
The small sphere struck the now dry, barren ground with a soft, crystalline sound, like glass settling into place. It did not splatter. It did not deform.
It remained perfectly round.
A dark crimson marble, polished and flawless.
The orb shimmered faintly in the darkness, its surface reflecting the empty expanse around it. And within that reflection—
A silhouette stood.
Still.
Watching.
The orb emitted a radiant glow of quiet danger, pulsing as if something alive had been sealed within its depths.
A clawed hand reached down slowly.
Carefully.
The fingers were sharp and curved, yet precise in their movement, handling the orb with deliberate restraint so as not to scratch its surface.
The insectoid’s eyes gleamed, multifaceted pupils catching the faint red light. Satisfaction flickered across its expressionless face.
It had not intervened.
It had waited.
And now, it collected its prize.
Without another sound, without disturbing so much as a grain of dust, the figure dissolved into shadow. Its presence vanished as though it had never existed.
The crimson glow disappeared with it.
