Harem System in an Elite Academy
Chapter 183: Descent Into the Hollow Chamber
CHAPTER 183: DESCENT INTO THE HOLLOW CHAMBER
The staircase wound downward in a steady, deliberate spiral, as though carved by someone with infinite patience and no regard for the natural layout of the earth. Arios kept his hand on the stone wall as they descended, not for balance, but to understand its texture, its age, the lingering mana woven deep beneath its surface. The stone felt neither cold nor warm—just there, timeless, like a wall that had existed long before any academy had laid claim to the island.
Lucy and Liza followed him closely. No one spoke for several minutes. The silence was not heavy, but attentive, stretched thin like a taut string waiting to be plucked.
A faint breeze still rose from the depths, brushing against their faces with unnatural consistency. It carried the scent of old stone and something faintly sweet—like crushed white petals that had wilted centuries before. The sweetness should have been comforting, but it wasn’t. It was misplaced, out of context, like perfume drifting through an empty tomb.
They turned another corner of the long spiral.
The glow appeared again.
Soft. Pale. A quiet pulse rising from far below, like a heartbeat buried deep in the earth.
Lucy stopped for half a breath. "It’s getting brighter. Whatever is down there... we’re getting close."
Liza’s ears twitched. "I don’t hear anything hostile yet. But don’t relax. Silence is worse."
Arios said nothing. He simply continued downward.
The stone beneath their feet had changed. The stairs were becoming smoother, the edges more refined. Earlier steps were rough—carved manually or with raw magic—but these lower steps were polished, precise, intentional. They belonged to a place shaped by a different type of creator. Someone who valued symmetry, ritual, design.
Lucy noticed it too. "This craftsmanship... it’s centuries old at least. Maybe more. The academy didn’t build this. They couldn’t."
Liza ran her fingers along the wall. "Feels like something ancient was buried under the island... and they didn’t even know."
Arios suspected the academy knew more than they admitted—but that thought he kept to himself.
They descended for what felt like another ten minutes before the spiral path widened. A soft vibration hummed through the soles of their boots. Not loud, not aggressive—simply present. A mana signature, stable but old, deeply embedded in the structure.
As they rounded the next curve, the staircase ended abruptly.
The three of them stepped onto a broad stone platform.
A cavern stretched before them.
And it was enormous.
The chamber dwarfed anything the island had shown above ground. A hollow, smooth-walled sphere carved with precision so impossibly perfect that no human tool could have made it. The ceiling soared high above, lost in dim shadow. The pale glow they saw earlier emanated from veins of faintly luminescent mineral embedded throughout the chamber walls, like mana-rich quartz veins chiseled by nature or forgotten magic.
But the true illumination came from the center.
Floating above a shallow circular indentation in the floor was a sphere of light—no larger than a lantern, but brighter, purer, concentrated like crystallized moonlight. It hovered silently, its glow casting gentle shadows that swayed with no source of wind.
Lucy exhaled very slowly. "This... is not normal dungeon architecture. This is a relic chamber."
Liza stepped closer, eyes narrowing. "Why is something like this under the academy’s exam site?"
Arios observed the sphere, his senses sharpening. It wasn’t a trap. It wasn’t a monster. It wasn’t any spell he could immediately categorize.
It was... waiting.
As they stepped further into the cavern, the ground shifted subtly—an almost imperceptible tremor that moved like a sigh through the stone.
Lucy froze. "Did you feel that?"
Liza’s tail stiffened. "The chamber reacted to us again. It’s alive. Not literally, but magically. Like the whole place is bound to a core."
Arios moved toward the floating sphere.
Every step he took, the glow strengthened. Not overwhelmingly, but with intent—as though acknowledging his presence, measuring him, weighing him.
Lucy’s hand brushed his sleeve gently. "Careful. You’re provoking a response."
Arios kept moving.
The sphere pulsed.
Once.
Twice.
Then very gently, the sphere drifted toward him.
Liza drew her dagger instantly, but Arios lifted a hand. "Standby."
The sphere hovered a few inches from his chest, humming softly.
Then—
It flared.
Light washed across the chamber like a gentle wave. Not blinding, not hot. Just... clarifying. Revealing. For a moment, the entire hollow room illuminated, reflecting off hidden carvings high above, off runic patterns embedded in the floor, off faint inscriptions that lined the walls.
Lucy gasped softly. "Arios... look at the runes."
The floor was covered in them.
Hundreds of glyphs. Thousands. Circular patterns overlapping like layers of a forgotten cosmos. Some were cracked from age, others pristine, untouched by time.
The sphere dimmed back to its original glow.
A faint shifting echoed above them—like stone adjusting, settling, or preparing.
Arios’ gaze traced the runes slowly. "It’s reacting to our presence. To mine, specifically."
Lucy swallowed. "It recognized you on the surface too... but this is stronger."
Liza folded her arms, pupils narrowing. "Feels like it’s scanning us. Or testing us."
The sphere circled around Arios once, twice, then drifted slowly toward the center of the rune formation. It hovered above a depression—like a pedestal meant to hold something.
Arios stepped closer.
Lucy and Liza followed cautiously, each ready to pull him back at the first sign of danger.
The sphere lowered.
Touched the ground.
And the runes awakened.
Lines of pale light shot outward, traveling through the entire circular pattern like veins filling with blood. The entire chamber thrummed, deep and ancient, as coils of mana awakened beneath them.
Arios’ eyes narrowed. "This is no ordinary chamber. It’s a mechanism."
Lucy whispered, "A nexus."
Liza hissed under her breath. "A gate?"
A rumble passed through the floor.
Slow. Intentional.
Something deep beneath the runes stirred.
A circular seam cracked open, dust drifting into the air as the stone slowly parted, revealing a descending platform—no stairs this time, just a silent mechanism lowering itself from ancient machinery.
Arios tightened his grip on his sword hilt. "We’re being invited."
Liza’s ears pressed flat. "Or lured."
Lucy’s eyes flicked rapidly between the moving stones. "The mana density below is high—dangerously high. But stable. Whatever is down there hasn’t decayed."
Arios watched the platform settle.
A soft white fog drifted out of the opening.
Warm.
Fragrant.
Alive.
He stepped toward the platform.
Liza reached out instinctively. "Arios—wait."
He paused, turning slightly.
Lucy’s voice was quieter. "We don’t know what’s below. We don’t know if we can come back up."
Arios’ tone remained steady. "This place isn’t hostile. If it wanted us dead, it had countless chances already. It wants to show something."
Lucy bit her lip. "That’s what scares me."
Liza sheathed her dagger reluctantly, growling under her breath. "Fine. But I’m going with you."
Lucy nodded. "Me too."
Arios stepped onto the platform.
Lucy stepped beside him.
Liza on the other side.
The mechanism hummed.
The descent began.
Slowly, the platform lowered into the depths of the unknown.
The chamber above faded from view, swallowed by darkness.
As they descended, faint lights flickered on within the shaft—soft blue sigils illuminating one by one in tall vertical lines, like descending through the spine of a massive magical apparatus.
The air grew warmer.
The fog thicker, but pleasant, not suffocating.
A low hum echoed far below.
Lucy whispered, "This doesn’t feel like a dungeon anymore."
Liza exhaled slowly. "Feels like a sanctuary. Or a vault."
Arios spoke quietly.
"No."
The light beneath them grew brighter.
"It feels like something ancient is waking up."
The platform continued downward—
And the next chamber revealed itself.
The fog cleared just enough to show outlines.
A vast underground garden.
Lush vegetation. Bioluminescent flowers. Vines creeping along stone pillars that reached toward a ceiling lost in shadow. Water flowed across smooth channels carved into the floor, glowing faintly with magical residue.
Central to it all—
A massive tree.
White bark. Radiant leaves. Roots weaving through the garden like a web of light.
Lucy gasped. "A... mana-tree. A living one. But they’re extinct."
Liza stared, breathless. "This island... isn’t just an exam site. It’s hiding a relic ecosystem."
Arios stepped forward.
The tree pulsed once—gentle, warm, like a heartbeat in the air.
The island had awakened.
And it recognized them.
The three of them stood there in silence, the soft glow of the great tree washing gently over their faces. For a moment, the island felt completely still—no wind, no distant echoes, no shifting stone or cryptic signals. Only the quiet pulse of the ancient mana, steady and measured, like a sleeping giant exhaling beneath the earth. Arios felt the weight of it settle on him, not as a burden, but as a confirmation that whatever lay ahead was larger than the exam, larger than the academy, larger even than the strange fate that had shaped his year so far. Lucy moved a little closer without speaking. Liza tightened her grip on her weapon, eyes fixed on the luminous roots. And beneath the glow of the underground world, the three of them understood—unspoken and without protest—that they had crossed a threshold. There was no turning back now. The island had chosen to reveal itself, and from this point forward, everything would change.
