Demon Progenitor Development Project

Chapter 130 Ubuyashiki Yoshiya

"I'm going to kill him!"

Muzan suppressed his fear and murderous intent, cursing under his breath. His expression became increasingly ferocious as he struggled to maintain his composure.

Muzan found it unbearable to hear the whole thing; this was clearly another monster like Yoriichi Tsugikuni.

One of these monsters is enough, why is there another one?!

He was about to explode inside the house, and if Shugo hadn't stopped him, Muzan would have definitely killed the couple.

Shugo grabbed Muzan's hand and tried to pull him away.

"Calm down!"

"Tanjuro is not Yoriichi Tsugikuni, he is going to die."

The word "death" silenced Muzan.

“You should be able to sense it, right? Tanjuro’s life force is constantly draining away. He’s awakened his Demon Slayer Mark. He’ll die at the age of twenty-five,” Shugo said, enunciating each word clearly.

Demons are able to sense the life state of humans, and Muzan is no exception.

However, Muzan had been immersed in the memories of everything that had happened to Tsugikuni.

“We don’t need to do anything, he will die,” Shugo added.

Muzan recalled the man with that sickly air about him; it seemed that was indeed the case.

Muzan fell silent.

"I remember when you skipped training before, didn't you say you were very confident in beating Yoriichi Tsugikuni?" Shugo added sarcastically.

"What Tanjuro? Why are you calling him so affectionately!"

Muzan got angry and forcibly changed the subject.

Shugo stroked the ruffled Muzan cat's fur gently and showered it with compliments.

The sound gradually faded away.

Muzan looked at Shugo suspiciously, wondering why he wasn't continuing to coax him.

Hiiragi suddenly had an idea.

He had always been puzzled by the reason why the Kitchen siblings were able to overcome the sunlight.

So many people turn into demons, but it was Nezuko Kamado who overcame the sunlight.

Is there anything special about Nezuko Kamado?

The most unique thing is that Nezuko has never eaten a human.

There is no difference between man-eating ghosts and non-man-eating ghosts; he had already conducted observations and experiments and found no difference.

At first, he could only attribute it to the protagonist's sister's special constitution.

However, the protagonist Tanjiro later overcame the sunlight.

Are people with special physical conditions appearing in wholesale markets?

Hiiragi is more inclined to believe that there is something wrong with the mountain where the Kamado family lives.

Despite searching for the Blue Spider Lily for so many years, there has been no trace of it. Although Shugo doubts how effective the Blue Spider Lily can be, it is still very frustrating.

Muzan poked Shugo in dissatisfaction.

"I'm asking you a question! What about Sun Breathing?"

Shugo snapped out of his daze and replied, "Sun Breathing is not something ordinary people can learn, and even if they did, it wouldn't be of much use."

Besides Yoriichi Tsugikuni, the founder of the original sect, the only other sect in the original work was Kamado.

We can monitor them afterward; maybe we can even catch the Demon Slayer Corps by the skin and wipe them out in one fell swoop.

Shugo had also had enough of the Demon Slayer Corps' harassment over the years.

They left the hill where the Zaomen family lived.

"Go collect all the plants and stones from the nearby mountains and send them to the laboratory for analysis."

Hiiragi casually found a subordinate to do the work.

A true corporate slave: ?! What an enormous workload!

The Ubuyashiki family's secluded retreat.

“Yasu.” Yuya Ubuyashiki, the current leader of the Demon Slayer Corps, waved to his son.

Yaozai ran over quickly and began to read the contents of the paper seriously.

The father has gone blind and needs Yaozai's assistance in handling affairs.

The Demon Slayer Corps didn't have many tasks at the moment, and they finished them quickly.

Ubuyashiki patiently teaches his son essential knowledge for the Demon Slayer Corps lord, such as how to handle relations with Tokyo and how to reconcile relationships with his teammates.

Yaozai was only five years old, a child with a three-headed figure, but his expression was not like that of a child. Instead, he was mature and sensible, patiently listening to his father's rather tedious teachings.

The Ubuyashiki father and son, one big and one small, sat side by side, looking as if they were printed from the same template. Their face shape and bone structure were identical, and even their faces looked very similar at first glance.

However, the father's face was severely disfigured.

Because of the curse, no Ubuyashiki generation has ever lived past the age of twenty, so the education of the heir must begin from a young age, without any delay.

While ordinary children were playing carefree, the members of the Ubuyashiki family had to study hard.

It's truly heartbreaking.

Ubuyashiki spoke leisurely for a while, his throat dry. He raised his teacup to moisten his throat and gave his son time to react.

After asking a few questions, Ubuyashiki looked at his son with a relaxed and contented expression.

His son is smarter than him.

The Ubuyashiki family has a successor, and so does the Demon Slayer Corps' mission.

However, the Demon Slayer Corps is currently in a very bad situation.

There are very few swordsmen left; only the descendants of the old generation of Demon Slayer Corps swordsmen still join, and many even leave because they don't believe in the existence of demons.

The ghost chose to lie low, using various companies, groups, and other overt forces to carry out its activities, and even relying on government power.

This made things even more difficult for the Demon Slayer Corps.

Not long ago, Ubuyashiki Yuya foresaw the location of the swordsman of the Sun Breathing technique and hurriedly dispatched a hidden person to invite him to join.

The result was a rejection.

The other party had absolutely no interest in the noble cause of killing demons to save the world, and was indifferent to the fact that killing demons could make money.

Afterwards, Kagaya Ubuyashiki sent people to inquire about the Kamado family and carefully studied Tanjuro Kamado's personality based on the report from the hidden one.

Tanjuro Kamado is indifferent to fame and fortune, unconcerned about his immense strength. He has no intention of making a quick profit and continues to diligently mine charcoal every day to support himself, only wishing to live a peaceful life with his family.

Moreover, the other party's increasingly weak body is indeed not suitable for joining the team, and well, there are no ghosts for him to kill.

It seems difficult to get Tanjuro to join the team. I'll try my best to get him to teach me Sun Breathing. Ubuyashiki Yuuya thought to himself.

"Father, is the Breath of the Sun important?" Kagaya asked.

He nodded leisurely, "A breathing technique named after the sun is naturally the nemesis of Muzan Kibutsuji."

"In this case……"

Looking at the intelligence report, Kagaya said in a calm voice, "We can invite Tanjuro's son to join the team."

"Sun Breathing is the Hinokami Kagura passed down by the Kamado clan, and Tanjuro will definitely teach it to his son."

He nodded leisurely: "The important thing is the Sun Breathing and the markings."
