Ironholm’s Prosperous Secret

In the lands of Terramyr, the remote nation of Ironholm had made an irreversible decision: to submit to the rule of the invading Demon King.

Thanks to this, in exchange for their loyalty, the foreign sovereign not only granted them protection but also blessed them with control over a "factory" driven by a new and grotesque variant of slime.

In their natural state, the slimes of Terramyr were harmless creatures, vital to the ecosystem. By absorbing plant debris, waste, and decaying organic matter, they dissolved everything inside themselves to obtain nutrients. Upon dying, their dried remains turned into an extraordinarily rich fertilizer that nourished the crops, making them inherently beneficial beings for life in general.

However, the mutated species birthed by the Demon King’s arts and entrusted to the rulers of Ironholm possessed the exact opposite property.

This new type of slime did not digest plant or animal corpses; instead, it devoured living matter with an insatiable appetite. The residue it expelled after drying did not enrich the soil; rather, it withered and poisoned fields upon the slightest contact, rendering the land barren as crops withered away.

In those early days, when the shadow of the war against the Demon King was just beginning to loom over Terramyr, humanity remained completely in the dark regarding the true nature of the enemy.

Around that time, adventurers' guilds began discussing a series of strange and disturbing discoveries made in the depths of all kinds of dungeons: the persistent discovery of female corpses abandoned in the deep dark.

Given the inherent dangers of the adventurer profession, finding bodies was not a novelty in itself; however, that every single victim belonged to the same gender was an anomaly too glaring to ignore.

Yet the most bewildering detail lay in the condition of the remains.

None of the bodies bore external wounds or signs of physical violence, remaining in an eerily intact state. Upon examining the symptoms, healers concluded that all the victims had perished from severe, sudden vital exhaustion.

What baffled everyone most back then was that there was no evidence of the women having been restrained or bound.

Instead, judging by their posture and appearance, it seemed as though they had simply weakened progressively until fading away and dying in complete silence.

During that time, the mystery deepened even further when, in nearly every inspection, a "viscous fluid" was found in the private parts of the deceased. However, in a world accustomed to the dangers and fluids of cavern creatures, the detail was not considered a major issue, overlooking the first dark signs of a large-scale tragedy.

Ultimately, the terrifying connection between those mysteriously deceased bodies and the viscous substance would not come to light until twenty years later, following the outbreak of open war against the Demon King.

"We've won again!"

"Long live the kingdom! Long live the great Demon King!"

In the present timeline, the streets of a prosperous city within the kingdom of Ironholm were wrapped in an atmosphere of festivity and debauchery.

"Glory to Ironholm! Glory to the Sovereign!"

"No one can stop us! The whole world will be ours!"

"Long live the Demon King! Long live the conqueror!"

"Look at those banners! Our flag flies high once more!"

"Our territory expands, and so does our wealth! We are invincible!"

The crowd fervently celebrated another crushing victory for the invading sovereign's forces, cheering the conquest of new territories for their ever-expanding nation with praise directed at their leader.

However, the reality was that a mere two decades ago, Ironholm was nothing more than an insignificant, forgotten country in a remote corner of the continent.

Despite that, in recent years, its national power and military influence had grown at a terrifying pace thanks to the sinister "gift" bestowed by the Demon King to whom they pledged allegiance. Driven by that dark blessing, their armies continuously expanded their borders, devouring neighboring nations and flawlessly executing their mission.

"Oh...♡ It's coming...!♡"

How had such a small and insignificant kingdom been capable of thriving and expanding at such a terrifying speed in so short a time?

"Ha... I'm getting bored of seeing this scene every single day..."

The secret of their rapid military advancement lay in a modest factory hidden in a strictly restricted zone on the outskirts of the kingdom, guarded day and night by top-security military perimeters.

"My life is coming out...~♡!"

Upon crossing the iron gates, the scene unfolding inside barely resembled a conventional industrial structure.

"Hurry up and force it out already!"

Inside, dozens of armed human guards methodically watched over numerous completely naked women, suspended in the air with their limbs bound and spread wide, while a dense, purple fluid gushed continuously from between their legs.

"Tch! This one isn't expelling as much as before!"

Every single prisoner held in the facility was an elf of sublime beauty and long, pointed ears.

"Come on, calm down, man..."

Upon reaching the climax induced by the parasitic creature within them, these elves repeatedly defecated and expelled the viscous substance, letting out uninhibited shrieks and cries that echoed off the factory rafters.

"...Well, even if it's not as much compared to before, it's still quite a lot... Besides, we captured a new one today."

With their faces completely melted in involuntary, uncontrolled pleasure, the elves' moans of ecstasy echoed throughout the installation alongside the casual conversations of the guards, just as the main gates opened to bring in a new captive fresh from the front lines.

"W-What are you going to do to me...?"

Restrained and completely naked, the newly arrived elf asked her question with a trembling voice as she watched the scene around her with visceral horror.

"Stop talking, livestock."

Her eyes sparkled with deep hatred toward the human guards, who, without bothering to answer, took a strange metallic device resembling a specialized vibrator and shoved it unceremoniously into her vagina.

"A-Ah...! Oh... oh...!"

As a result, a stifled cry escaped her as she felt the foreign object force its way deep into her abdomen.

"...."

Without flinching, the guard in charge turned the crank integrated into the base of the instrument with practiced hands and methodical routine.

(SCHLICK!)

And after completing the turn, he pulled the artifact out in a single yank.

"Hoo...♡"

However, despite the instrument being removed, the elf's abdomen remained strangely swollen, as if a considerable volume had been deposited inside.

(Glup, glup, gluup!)

Seconds later, the swelling began to shift slowly, writhing and twisting beneath the skin of her stomach like a coiled serpent.

"Fughu...!♡"

Because of this, the captive tried to resist the sensory assault, her face locked in an expression of intense agony.

(Glrsh... glrsh...!)

Bit by bit, the bulge in her belly began to shrink with a dull internal gurgle.

(GURGLE-GURGLE...!)

Yet far from marking the end of the torment, that was merely the prelude to something infinitely worse.

"O-Oh...? Ohhhhh...!♡"

As her first uncontrollable moans began to escape, the mass of mutated slime that had entered her body ascended toward the center of her organism.

(Crac... cloc... glu...!)

And upon reaching its destination, the parasitic creature began to greedily devour the "nourishment" concentrated inside her.

"Ahhh...♡ Fuuh...♡"

It was only six years ago, after intensive research revealed the true nature of that viscous substance, that the world of Terramyr finally understood the truth: that slime variant, birthed by the Demon King’s dark arts, was actually a synthetic lifeform capable of dissolving and processing pure magical energy to use as nutrients.

"Haaah...♡!"

Thanks to that discovery, the authorities and scientists of Ironholm began conducting continuous, ruthless experiments to exploit those properties for their own gain...

"Uhhh♡ Aaaaaah!"

As a result of those tests, they unlocked the ultimate method to colonize the bodies of their captives, utilizing the parasitic slime to invade, dissolve, and endlessly extract the magic reserves of other living beings for their own benefit.
