Demon Progenitor Development Project

The grotesque stitched-together monster stared intently at Shugo, while a sinister smile appeared on Ubuyashiki Eiji's distorted face, his mouth stretched wide as if he were about to tear his entire face apart.

After a long while, it finally managed to squeeze out a low, hoarse voice from its throat.

"Fujiwara Shugo, you shameless and despicable scoundrel! Give me back my son right now! Otherwise, today is your death day!"

Upon hearing this, a disdainful sneer flashed across Shugo's face. He raised his head and met the Stitched Monster's venomous and murderous gaze without fear, responding coldly.

"Hmph! You still have the nerve to say that? You don't care at all, Muzan was raised by me with great care!"

"So you don't care? You've given me a chance to care!"

After his eldest son was sent to the Fujiwara Kita family, his biological father could only see him a few times a year. How could such a father-son relationship be cultivated?

This is clearly Fujiwara Shugo deliberately severing their father-son relationship!

Looking back on those events, Eiji Ubuyashiki felt even more aggrieved.

"You raised him? You raised a blood bag?" Ubuyashiki Eiji mocked.

"Isn't he the one you tricked out of me?"

"I've always been curious, it's as if you already knew he would become a ghost, and you placed your bet in advance. Did you have precognition, or did you accidentally receive information about the future?"

Ubuyashiki Eiji's hoarse voice struck at Shugo's deepest secret, which was also the source of his inspiration for manipulating the Ubuyashiki clan using so-called precognition.

Shugo's face remained largely unchanged, but he was secretly surprised. He couldn't underestimate the ancients; Ubuyashiki Eiji had already guessed part of the details correctly.

His behavior back then was indeed abrupt and strange, which is an unavoidable flaw.

According to Eiji Ubuyashiki, not answering is already a tacit agreement.

"Back then, I deliberately cultivated him, cut off all his connections, and made Muzan trust only you. Wasn't that all I was waiting for to reap the rewards? If I hadn't had the Emperor assassinate you, Muzan, you would have been dead long ago, wouldn't you?"

The subtext is that Muzan will be drained of his blood after he becomes a demon.

Hiraga is displeased; this is clearly a baseless speculation!

He didn't stop Muzan from making friends! Nor did he intend to drain Muzan dry!

...At most, he would only kill him when things were hopeless, such as when Muzan insisted on causing him trouble.

Hiiragi touched his forehead guiltily.

Komaji really wanted to go deaf at that moment.

Komaji: I shouldn't be here.

Oh, it's no use poking it deaf, the ghost will automatically recover!

Can he possibly hear the secrets of his boss?

Tongmo pricked up his ears, listening with great interest.

Wait, so Muzan and this giant monster are father and son!

Muzan-sama was still taken away by Shugo-sama!

She was raised by someone!

Doma remembers that kind of relationship between Muzan-sama and Shugo-sama, right?

Child adopter?

Isn't this just like Genji?

Doma was already rave about the gossip, inwardly praising himself for accepting the mission and thanking Komaji!

Ubuyashiki Eiji's gaze had already turned to the awakened Muzan Neko.

Muzan remained quiet and didn't say anything, nestled obediently in Shugo's arms without moving.

Shugo doesn't think Muzan will be swayed by just a few words, unless Muzan's head is as sharp as a certain great monster general's and has been squeezed. However, he is definitely suspicious.

I'll explain after I've finished hitting you.

Slightly guilty, Shugo secretly offered an explanation in his mind.

【…】

Once this matter is settled, I'll tell you my secret, okay?

Having received no response, Shugo lowered his stance and tried to coax her with a few words.

【…Don’t lie to me!】

Muzan could only issue such a weak warning, like a kitten hissing at its owner to stop trying to pet it when its fur is about to be plucked bald.

Okay. I've never lied to you before, have I... at most I've just changed the subject or only told part of the truth.

[Liar! Big liar!]

Muzan was so angry that he yelled and screamed in the mental channel, but he still swallowed his anger and reluctantly jumped out of Shugo's arms, transforming into his demon form.

It's the form with its lower body covered in black hair and a big mouth.

Shugo looked at Muzan, who was naked from the waist up, and after a moment of silence, said, "Muzan, why don't you change back?"

Muzan understood Shugo's gaze, snorted coldly, and, having already developed a rebellious streak, completely ignored him. The spiked whip and the tube whip behind him emitted a crisp popping sound, heading straight for Ubuyashiki Eiji.

Shugo sighed, knowing that Muzan was just being stubborn, and didn't say anything more.

He needed to vent his anger; he didn't want to become a target.

Muzan was indeed throwing a tantrum, and his fighting style was completely chaotic; he was simply using Ubuyashiki Eiji as a punching bag.

The arm transformed into a massive fleshy arm, and the enormous mouth at the end of the arm opened wide, tearing chunks of flesh from Ubuyashiki Eiji's body.

The giant monster, in pain, instinctively retaliated, but Muzan nimbly dodged it.

Damn!

Eiji Ubuyashiki deeply understood the inconveniences of his large size, but he could no longer reduce his size.

So only...

Ubuyashiki Eiji's face darkened, but he gritted his teeth and stopped retaliating. Instead, he bent over, straining his abdomen until his face turned purple.

The person's condition resembles that of someone suffering from constipation, and they are currently undergoing a process of consuming grains.

Suddenly, an egg fell from between the other person's legs? (It already has a woman's head, so it's only natural that the Frankenstein's monster is a hermaphroditic creature and can reproduce!)

Ubuyashiki Eiji breathed a sigh of relief; the entire monster felt refreshed.

Shugo paused for a moment as he released his empty blade, startled by this bizarre and strange situation.

The egg quickly hatched, and a humanoid monster covered in slime roared as if celebrating its birth.

After ending its roar, the hideous monster charged towards Muzan and Shugo, its eyes filled with bloodlust.

Hiiragi: So you can mass produce units? Where did you come from, Zerg Queen?

With the first egg, there was a second one. Having overcome her psychological barriers, Eiji Ubuyashiki was now fearless!

If he doesn't have a baby soon, he'll be the one who dies when these ghosts in front of him are killed!

Soldiers emerged like dumplings being dropped into a pot, charging menacingly towards the ghost's side.

Komaji and Doma finally came in handy, starting to eliminate the small monsters one by one.

The snowflake-shaped compass needles and the temperature drop caused by frost are clearly visible.

These lesser monsters are born quickly and die quickly; their numbers are nowhere near those of elite veterans like Doma and Komaji. For a time, the battle was completely one-sided.

Suddenly, at the ancient underground grotto ruins that were once silent but have now turned into deep pits, an extremely sharp sword aura shot out from underground like lightning, soaring straight into the sky.

Immediately afterwards, a figure was seen slowly and laboriously crawling out from underground.

The figure was covered in dust, looking disheveled. His purple robes had turned grayish-black and were no longer clean. Hei Shi Mu quickly crawled out and peeked at the battlefield.

Kokushibo: ...I always feel like he missed out on a lot?
