Transformed into Cosmic Horror in a Sci-Fi Universe

[ Of course, a Heavenly Demon is essential in martial arts stories. Whether as a villain or protagonist! ]

But this isn’t quite traditional martial arts fiction.

Nowadays, shouldn’t a Heavenly Demon be a woman to really hit the spot?

I’ve learned that’s what passes for traditional martial arts fiction these days.

I’ve seen quite a few of those in the newly emerging universes.

First, the Heavenly Demon killed countless martial arts masters in a war 100 years ago, and in the end, was sealed away along with the Martial Alliance Leader’s ultimate technique.

Barely surviving by separating their soul with a soul-splitting technique, they had to spend 100 years recovering their inner energy.

After 100 years, having regained enough strength to create a new body, the Heavenly Demon is resurrected.

[ Kuhehe, finally. Finally, this day has come. Now that I’ve returned, this martial world is finished! ]

But something went wrong, and all the accumulated inner energy disappeared?

Even worse, the body became that of a beautiful woman.

[ Huh? Uhhh??? ]

Realizing something was amiss, the Heavenly Demon examines their body.

[ W-What in the world is this! Where has my decades’ worth of inner energy gone! And this body? This voice? Anyone can see it’s that of a woman! ]

Of course, the Heavenly Demon was originally quite pretty, so in their powerless days, they were often mistaken for a woman and even suffered abuse from martial artists who enjoyed male companionship.

That’s the kind of backstory explaining why they hate the world and want to destroy the martial arts world.

Now they’ve become a true woman, undeniably beautiful with brown ponytailed hair, perky breasts, and a slender waist.

[ T-This can’t be! Did the resurrection technique fail?! ]

Hehehe, let’s see how this Heavenly Demon, now turned into a woman, will survive.

#

Whether due to a malfunction in the resurrection technique, all inner energy had disappeared and the body had transformed into that of a woman.

However, the Heavenly Demon Baek Hui was not flustered…

“Ah, no!! My inner energy! My crotch! Aaaargh!”

He was extremely flustered.

“Ugh! There’s no choice now. I’ll have to build it up from scratch. With a woman’s body, there will inevitably be limitations… but I should still be able to recover to about 80% of my original efficiency.”

Of course, befitting a Heavenly Demon, he quickly regained his composure and formulated a plan.

First, breathing.

The Heavenly Demon’s core technique, the Demon Absorption Breathing Method, is a demonic art from the Evil Sect that steals life force from surrounding living beings and converts it into inner energy.

It was a terrifying technique befitting the Heavenly Demon of the Evil Sect, causing surrounding life forms to wither and die just by breathing.

After building up basic inner energy with this, the next step would be to use the Heavenly Demon Absorption Technique to completely drain the life force from any living being touched, causing them to wither and die while accumulating inner energy.

With these demonic arts, the Heavenly Demon was able to gather decades’ worth of inner energy in just over ten years.

This time would be the same.

The only difference was that there was no foundational inner energy to start with, and being in a woman’s body meant less inner energy could be accumulated compared to when he was a man.

‘It’s frustrating, but what can I do? The resurrection technique is a one-time skill that can’t be used twice. I must see this through to the end.’

Still, he wasn’t worried.

Although the efficiency was about 80% compared to a male body, the inner energy that could be accumulated through the Demon Absorption Breathing Method and the Heavenly Demon Absorption Technique was limitless.

In exchange for only being able to use life-devouring demonic arts forever, that vitality would be absorbed from surrounding life forms.

In other words, as long as living beings existed, the Heavenly Demon’s inner energy was virtually infinite.

Even though efficiency was reduced in a woman’s body, the infinite inner energy remained unchanged.

It would just take a bit more time.

Thinking this, he closed his eyes and inhaled.

He could feel the surrounding life force being drawn in along with the air.

It naturally circulated through the body once, beginning to open up blocked meridians.

Fssssss─

There was a burning sensation as if the life force was scorching the blood vessels as it passed through.

But the Heavenly Demon, seemingly accustomed to it, continued to inhale and exhale, channeling the life force through the blood vessels.

The impurities inside the body began to burn away from the life force and were expelled through the skin.

Black, congealed sweat-like substances flowed out of her body.

Being naked, the black sweat trickled down her perky breasts and slender waist, dripping onto the ground.

The life force that had circulated through the entire body then opened the closed gate of the dantian and entered, becoming inner energy.

A tiny amount.

A truly minuscule amount of inner energy had accumulated.

“Inhale. Exhale…”

After circulating and opening the meridians and dantian, the Heavenly Demon looked down at her naked body covered in sticky impurities.

“Oh my, I need to wash up.”

As a foul odor rose, the Heavenly Demon frowned and surveyed the surroundings.

Then, she took a step towards where she smelled water.

Thud.

Suddenly stopping, she looked around blankly.

“……”

And after a moment, she realized.

“Ah, I can’t use the Heavenly Demon Step right now. How inconvenient…”

Heavenly Demon Step.

The highest level of lightness skill that allows one to move dozens of li in a single step.

But now, with insufficient inner energy, such a feat was impossible.

Realizing she had become an inconvenient body, the Heavenly Demon clicked her tongue and walked towards where there was water.

Although her body felt sticky, unpleasant, and smelled bad, as the Heavenly Demon, she couldn’t stoop to running around vulgarly, so she walked slowly.

After walking for about 20 minutes, she finally arrived at a pond in the forest where water had collected.

“Tsk, to think I have to wash directly without being able to move the water.”

Originally, she would have used martial arts to move the water and wash directly.

No, after accumulating a certain level of inner energy, there wouldn’t even be waste products in the body, so there would be no need to wash at all.

It had been an extremely long time since the Heavenly Demon had performed the act of washing her body.

Moreover, since it was a woman’s body, the awkwardness was doubled.

“Tch, what an inconvenient body. At least it’s more flexible compared to a man’s body. This could be useful.”

While washing, she tried moving her body in various ways, and as a result, she learned that although the overall physical abilities were weaker compared to a man’s body, the flexibility was remarkably high.

This felt like something that could be well utilized in martial arts.

“Well, that Sword Princess also used her body’s flexibility and elasticity incredibly well. Though I killed her.”

The Heavenly Demon smirked, recalling the past.

But then.

“Whoa, what the hell is this?”

“Wow, isn’t this something?”

A group appeared at the pond where she was washing.

“We came to check who was making water sounds in our territory, and look what we found? This is a real catch!”

They were a group of bandits who had claimed this area as their territory.

Four in total.

A big guy wielding a huge axe, another of similar build holding a flail.

A slightly smaller one with a greatsword.

Lastly, the smallest one holding a thin rapier.

‘That one is the strongest.’

She could tell without even sensing their inner energy.

The Heavenly Demon’s instinct for combat was telling her.

The shortest one with the rapier was the strongest among them.

“Hehehe, hey miss. Since we’ve met like this, why don’t we have some fun?”

“Being naked here means that, right? You’re trying to seduce us, aren’t you?”

The bandits approached the Heavenly Demon with lecherous expressions.

Seeing this, the Heavenly Demon made a disgusted face and said,

“Be on your way. If you knew who I am, your hearts would stop from shock.”

Still, these were the first humans she had met since her resurrection.

Thinking she might show a bit of mercy this time, the Heavenly Demon kindly gave them a warning.

Even if she caught them, she couldn’t use the Heavenly Demon Absorption Technique yet, so she could only slowly absorb their vitality, and there wasn’t enough time for that.

“Hahaha! This woman’s got some spirit that could pierce the heavens. Come on, tell us who you are, pretty one.”

But starting with the biggest guy wielding the axe, the rest of them didn’t back down either.

It was natural.

What stood before them was a delicate and, moreover, beautiful naked woman.

“Sigh… To ignore this one’s warning, truly foolish beings.”

Saying this, the Heavenly Demon looked around and picked up a fallen branch.

“Huh? Puhahaha! Don’t tell me you’re going to face us with that?”

“Has she gone mad from fear?”

“It’s probably just for self-defense.”

The bandits sneered.

But there was one who couldn’t laugh.

“…Her stance is perfect.”

It was the smallest bandit with the rapier.

“Everyone, don’t let your guard down. She might be more skilled than we think.”

“Huh? Brother, she’s just a woman. We can just have some fun after a long time…”

“Hey, wait!”

As the big man with the axe said this and stepped forward towards the Heavenly Demon, just as the bandit with the rapier was about to stop him,

“Hehehe. I’ll show you a sword technique too good for the likes of you. This is the Sword Princess’s sword.”

Whoosh─

The Heavenly Demon’s body twisted with incredible elasticity.

And then her body sprang forward, propelled by that elasticity.

At its end was the branch she had picked up earlier.

Thwack!

The tip of the rotating branch made contact with the approaching axe-wielding bandit.

Whump!!

“Ugh?!”

The axe bandit staggered back two or three steps and fell to his knees.

“W-What?!”

At this situation, not only the axe bandit but everyone was greatly shocked.
