Demon Progenitor Development Project

Shugo looked at the unusually calm Kokushibo and said coldly, "Kuroshibo, you should calm down."

After saying that, Shugo raised his hand, intending to use a spatial vortex to swallow his opponent.

Although his Blood Demon Art's spatial storage and teleportation abilities are inferior to Nakime's, its offensive capabilities far surpass them.

"Lord Fujiwara, I do not wish to be your enemy."

As if sensing something, the black mist even condensed into the internationally recognized gesture of surrender—hands raised.

"Oh?"

Shugo did not lower his hand, but stared at the black mist with a scrutinizing gaze.

He needs intelligence.

He could sense that Muzan was now deep underground.

The fact that Muzan didn't watch the battle from the outside but went deep underground already foreshadowed bad news—this stupid cat had been caught.

However, since the heart is not responding, it should be in a safe state for the time being.

Kurogiri knew that Fujiwara Shugo wanted his pledge of allegiance.

"I'm sorry, sir, I don't want to do what you're asking, nor can I do it."

The black mist muttered to itself, "Although the master I serve makes me work every day, he always sends me out..."

Is it really the most troublesome and disgusting mental discipline?

And 'he' lacks manpower?

Having deciphered the message from the black mist's words, Shugo narrowed his eyes and, without saying anything more, simply said, "You may continue!"

Hiiragi walked straight inside.

Before long, they encountered a river made of corrosive liquid. Shugo used a short teleportation to cross it and soon encountered the humanoid monster that Doma and Komaji had encountered.

These monsters, aside from their decent strength and speed, are basically easy targets that can be killed with a single strike, but there are just too many of them.

In that narrow and long passage, countless monsters with ferocious faces and vaguely human-like shapes surged forth from the depths of darkness like a surging black tide.

They bared their teeth and claws, drool dripping from their mouths, as if they wanted to tear apart and devour all living things.

As the monster army continued to advance, the monsters at the rear were unable to continue charging forward because the front was already crowded with their companions.

However, these ferocious creatures did not stop there. Instead, they raised their feet without hesitation and stomped hard on the backs of their kin.

And so, one monster after another stepped on the bodies of the monsters in front, forming a "bridge" made of flesh and blood.

This terrifying "bridge" was stretching towards Shugo, who was standing at the other end of the passage, his eyes filled with a voracious appetite.

"He has intellectual disabilities."

Shugo simply set up a spatial vortex in the direction they were charging from, and these foolish monsters kept rushing towards them, showing no ingenuity whatsoever.

Shugo pulled over a monster, and after examining it, he discovered a fact.

These mindless monsters, whose minds are consumed by nothing but food, seem to be... ghosts too.

However, it is an unknowingly extremely degraded demon, unable to generate blood demon magic, devoid of intelligence, resembling a wild beast with only brute strength and a certain degree of self-healing ability. All its characteristics conform to those of a low-level demon.

This monster, whose bloodline is so thin that even the aura of a demon cannot be discerned, is probably beyond Muzan's control.

Shugo had made an assessment of his potential opponents.

We need to hurry up and prevent that old guy from running away.

Following the faint guidance from his heart within his chest, Shugo placed the spatial vortex in front of him and headed directly towards Muzan's location.

Ubuyashiki Eiji is deep underground.

The art style of this place contrasts sharply with its surroundings, making it seem completely out of place.

Upon entering the house, the first thing that catches the eye is the intricately carved furniture. It is exquisitely crafted, and every detail showcases the superb skills and boundless creativity of the artisans. The furniture is carved with lifelike floral and bird patterns and inlaid with dazzling gemstones.

Then look at the expensive silk bed. The soft and smooth silk fabric exudes a faint luster and is embroidered with exquisite patterns, like a magnificent and colorful painting unfolding on the bed.

Being in such a room, one is drawn to its unique style and experiences an elegant aesthetic atmosphere.

If you didn't step outside and stand there surrounded by a pale, fleshy blanket, you probably wouldn't believe that such a beautiful dwelling existed here.

As a nobleman, Ubuyashiki Eiji had high standards for his quality of life.

He wouldn't have wanted to live underground if it weren't for the need to control Tokuko.

Tokuko was originally the name of the Pale Flesh Blanket. That may not be the most accurate name, but it was its original name. After devouring countless living beings, it was transformed into this form by Eiji Ubuyashiki through multiple modifications.

When Eiji Ubuyashiki stole Muzan's blood from the Fujiwara residence, he not only used it for himself, but also conducted experiments as a precaution.

The test subjects were Lady Tokuko and her son, whom he had banished. (In the Heian-kyo arc, he attempted to eliminate Muzan's stepmother and younger brother who had risen to power.)

The blood that was stolen was somewhere between humans and ghosts, its nature was uncertain, and no one knew what its effects would be.

Kurogiri-kun and Lady Tokuko have turned into a large chunk of meat that only knows how to eat.

Ubuyashiki Eiji suspected it might be related to bloodline, so he conducted experiments on his son, the future Kurokiri-kun. He was a successful sample, but he permanently lost his physical body and could only exist in that form.

The pressure to control Tokuko is increasing. It seems she has consumed too many humans and her mind is becoming increasingly confused. If it weren't for Ubuyashiki Eiji's spiritual blood demon magic to control her, she would be in serious trouble.

This thing's first instinct is to devour all life, not to be as quiet as it is now.

As a result, Eiji Ubuyashiki was also trapped here and could not leave for long.
