The Obsidian Princess and the Seven Dwarves -2-
"Schlurp!! Schlurp!!"

"Hngh…♥ Haaah…♥"
With Mari's sweet moans spilling from her lips as my soundtrack, I slurped away at her pussy, feasting on her nectar, until we finally arrived at Rocktustaji—the southernmost city of the dwarf kingdom, home to Bitan Fortress.
Barunni hadn't lied. Entry was strictly controlled; not even fellow dwarves could pass without permission. Yet we slipped inside without issue. And there, at the city's absolute southern edge, stood the towering, colossal fortress wall dividing the city from the outside world.
Beyond the wall lay a massive underground passage plunging even deeper. Unlike typical subterranean cities and tunnels lit by myriad light sources, this one had none—swallowed by endless darkness.
Atop the wall facing that passage bristled with enormous magic cannons, giant ballistae, bomb launchers, and a full arsenal of dwarf weaponry. Armored dwarves—presumably the gunners—stood guard in meticulous, unyielding formation.
"Hoo."
According to the dwarves, the current guard was substantial, but before the Demon King War, even more troops had been stationed here. Not that it mattered. Our goal lay beyond that fortress, down the passage.
"So, the city where the Obsidian Princess was is beyond there, right?"
"Fua-fu~"
Mari began explaining the target's location at my words. She'd been the one to recommend the Obsidian Princess during our last marathon meeting.
The Obsidian Princess dated back to the era when Mari's original, the Rose Witch, was alive (witches lived forever). Before the Demon King was even born, she'd died buying time for her seven finest knights and her people to evacuate during one of the periodic monster floods from the northern demon realm.
Back then, the dwarf kingdom centered on the south, not the north like now; this area had been uncharted wilderness.
"Then why do the dwarves live up north now?"
"Fua?"
Mari didn't know either. Her original had died while the kingdom was still in the southern Arakasia Mountains.
Something must've happened in between...
Not important. What mattered was the Obsidian Princess's location. She'd been buried in one of the holy cities back then: Volcanix.
"You know where Volcanix is?"
"Fua~"
Mari nodded. Her original witch had kidnapped dwarf engineers to build a massive cavern and castle beneath the Forest of Beginnings, touring their cities in the process and memorizing the layouts.
"Good. Stay put inside for now."
"Fua~"
I stored Mari in my Living Death King's territory. Everyone except Nero was already tucked away there. My permission only covered entry to Rocktustaji, not beyond Bitan Fortress. Sneaking past seemed wiser.
Mari or I could've used stealth or teleportation magic, but we opted for something quieter and more discreet.
"Count on you, Nero."

"Nyaa~"
Nero had the best stealth among us. If she got caught, we'd all be busted.
—Shlrp.
My shadow suddenly expanded like a swamp, swallowing my body. Nero's skill,
Nightmare Shadow Reverse World
, pulled allies into the shadow realm.
Originally for sealing enemies, dragging them in for Nightmare Larva battles in a shadow-manipulated world, or stealth movement. Now more versatile in reality.
The shadow world mirrored ours but lifeless, everything pitch-black and inverted.
"Nyang~"
Nero guided me past the fortress. No guards here, naturally. Just us.
Once we'd cleared the wall and put some distance—
—Vmmm!!
—Shunk!!
"Good work, Nero."
"Nyanya~"
Back to reality, beyond the fortress.
"Come on out."
—Shlrp.
"Au!!"
"Uue!!"
"Fua~"
"Dau."
"Hau♥"
I released the Living Deaths from my territory. Sure, I was strong enough solo—thanks to reverse-engineered stats boosting combat—but necromancy was my core build. My undead were my weapons, my spells. This was like drawing from inventory.
Plus, eye candy mattered.
"Formation B."
"Au!!"
"Uue!!"
"Fua~"
"Dau."
"Nyaa~"
"Hau♥"
They took positions: tankiest Dena up front, me (next tankiest) at rear for ambushes. Melee DPS Kangjang behind Dena, ranged Mari and Masa mid, healer/reviver Sia right in front of me. A formation we'd drilled outside of sex.
The lightless tunnel was daylight to us undead, but caution never hurt.
"Maintain formation, advance. Mari, lead on."
"Fua~"
Mari navigated flawlessly—her ancient dwarf kingdom knowledge no bluff. Structure unchanged; dwarves were conservative about new tunnels.
Some new paths appeared, but—
—Whisper...
—Down there...
"Hm, thanks."
Nearby wraiths guided us.
No monster ambushes. Our unrestrained auras scattered them; we sensed them fleeing.
Undead stamina, supreme ranks, speed or teleports—progress was swift. Two days, with pit stops for sex.
This mountain range splits the supercontinent; no wonder it's vast.
"Fua~"
Mari signaled we were almost there. (Weakest physically, she flew with acceleration spells.)
Should've teleported...
I'd run hoping for corpses; found some in ruined ancient dwarf cities en route, but nothing useful.
Regrets aside, we passed the massive tunnel into Volcanix.
"Hm?"
Unlike prior cities, something stood out.
"Holes?"
"Uuu?"
A holy site dwarf city dwarfed modern metropolises, buildings preserved via ancient tech. Faded grandeur lingered. But the floor, ceiling, walls—riddled with cheese-like holes.
"Like worm-eaten."
"Uue.."
Holes dwarfed skyscrapers in diameter.
Barunni's words echoed: "Arakasia Great Death Worm", disaster-rank beast.
This world had a few like El Cuero; this worm-kin lived in southern deserts but claimed a mountain spot. Earth-scale: 1.5km long, 150m thick—pure calamity.
Rarely surfaced; its excrement was valuable, so dwarves left it be. Called "Arakasia Bull Worm" locally.
"Fua~"
Mari confirmed it hadn't existed in her time.
"Disaster-rank, huh... prime material."
"Dau."
"Hau♥"
Masa and Sia nodded; Sia especially, from same-rank stock, bobbed vigorously.
We eyed the central Volcanus Temple, her tomb. Unlike elsewhere, pristine—no holes.
Heading there—
—Grrrrumble!!!
"Hm?"
The ground and depths shook violently.
"Dau!!"
"Nyaa!!"
Masa and Nero—best armored—warned me. I sensed the source.
"Speak of the tiger..."
Our unleashed auras had drawn it, quaking toward us.
—Krummm!!!
"GRRROOOOAAARRR!!!!!"
The ceiling above exploded; a colossal form emerged. Annelid body, rubbery skin studded with protrusions.
"GRRROOOOAAARRR!!"
Over 100m maw filled our view, teeth like buildings.
Arakasia Great Death Worm.
It roared in fury, shaking the city. Intel said death worms ate minerals, not meat—incidental human swallows only, no hunts.
"GRRROOOOAAARRR!!!"
But this rage targeted us; its chasm-mouth charged.
Hostile confirmed.
"Fine by me. Planned to kill it anyway."
No sweat. El Cuero proved "disaster-rank" was no match here.
"Girls. Let's do it."
"Au!!"
"Uue!!"
"Fua~"
"Dau!!"
"Nyanya!!"
"Hau♥"
—Groooaa!!
—Fwoosh!!
—Czzzzt!!
We and the Living Deaths unleashed our auras.
—Grrrumble!!
Pale black death aura spread, vibrating air and earth, warping space, withering life.
We drew weapons, battle-ready—
—Krummm!!!
And attacked.
"Hngh!!"

Wraith Heart Sword - Black Death Flame Slash
—Fwoosh!!
I drew my heart sword, infused black flames, slashed—a crescent longer than the 150m-thick worm hurtled forth.
"Auuaa!!"

Living Death Heart Fist + Hellfire Demon God Art + Dragon Vortex Palm
Emperor Dragon Vortex
—Krummm!!
Kangjang wrapped her fists in hellfire and heart-force, swung—a massive ominous eastern dragon-shaped fist blast.
"Uue!!"

Sword of the Fallen Saint
—Fwoosh!!
—Vmmm!!
Dena swung her sword, unleashing her rare Immortal Brave ranged attack. The undead hero's holy sword blended dragon power and flames into a massive pale slash.
"Fua~"

Death's Apex Strike
—KABOOOOOM!!!!!
Mari conjured an ominous black magic circle; a death-force beam lanced from it toward the worm.
—Groooaa!!

"Dau!!"
—Clank!! Clank!!

Living Death Artillery Corps
—BOOM!! BOOM!! BOOM!!
Masa pulled siege weapons from her Necro Armory sub-space. Pale flames heralded anti-air cannons bigger than standard.
They belched death-flame shells, quaking the earth.
"Nyanya~"

Shadow Nightmare Binding
Nero shadowed her hand, swung. Worm shadows solidified into unbreakable threads, binding its bulk.
—Czzzzt!! Czzzzt!!

"Hau♥"
Death Holy Lightning Impact
—KABOOOOOM!!!!!
Sia fired a death-holy black lightning beam.
Seven Necros
The seven attacks harmonized into a cataclysmic blast.
"Krroooaa!?"
The worm sensed doom, twisted to evade—too late. Too massive. Nero's bindings held firm.
—Crunch!!
"KROOOAA!!!"
The fused strike hit dead-on—
—KABOOOOOM!!!!
The death worm burst spectacularly into a starburst.
