Demon Progenitor Development Project

Muzan's consciousness was hazy, his thoughts were like meat being brutally churned in a blender, his body was like flesh being roasted in an oven, like meat being simmered, wanting to release but unable to find a way.

It felt like returning to the initial darkness.

Breathing, struggling, wriggling, suffocating.

So sad.

So painful.

Someone please save me.

The devout faces, distorted and bizarre like abstract paintings, whisper prayers for divine protection before the merciful statue, seeking something unattainable.

The images of servants and nobles praying to gods and Buddhas in the past flashed through my overheated mind like a kaleidoscope.

Imitation is a child's instinct.

The young learn from the elders to pray to the unknowable gods.

God, save me, God.

The statue, which pities humanity, cracked open in a smile at the dying believer, as if mocking the mortal's painful struggle.

God loves the world? That's a human illusion.

Humans are born to suffer; God doesn't care.

The disease mocks the struggles of mortals and continues its rampage.

Extreme heat turns to extreme cold, as if one were naked in the dead of winter, bones groaning in pain, muscles twitching.

"...and he can't get the medicine down his throat..."

"...It's very dangerous..."

"...has been running a fever..."

The hushed conversations of the crowd turned into white noise on the surface of sleep, and everything was indistinct.

Only the panic and anxiety in one's words leave a brand on the soul like a branding iron.

An inexplicable fear swept over my heart.

That is life's resistance to death.

"...Use strong liquor...to apply a warm compress..."

A calm voice emerged.

"The fever has gone down!" The joyful voice clearly reached my ears.

A hand touched my forehead, its cool temperature penetrating my skin.

Muzan, whose consciousness had become slightly clearer, tried to open his eyes, but could see nothing.

Noticing that his eyelids were slightly raised, Shugo said a comforting word in a gentle voice.

"Go to sleep, you'll get better."

Muzan relaxed, and his consciousness completely fell into the dream.

Afterwards, the head of the Fujiwara Hoku family had a special talk with his eldest son.

“Send that child back.”

The head of the Fujiwara family commanded in an unquestionable tone.

It's so unlucky for a child destined to die young to die in their own home.

“The news has already spread; sending it back now would be burying our heads in the sand.” With a slight sinking feeling, Shugo organized his words, trying to persuade his adoptive father.

“Doing this would make us seem too guilty, which would be detrimental to our reputation,” Shugo calmly analyzed.

"We should keep them here for at least a while, and we can use this opportunity to build the reputation of the Fujiwara Kita family. A child who was predicted to die young has survived in the Fujiwara Kita family..."

Before he could finish speaking, the head of the Fujiwara family already understood.

“If it weren’t for Agu, this wouldn’t have happened today…” Shugo added another reason.

The head of the Fujiwara family interrupted his eldest son, looking at him with a deep gaze.

"I hope you don't put the cart before the horse."

……

7 days after the shocking event:

This incident made me realize that the relationship between Agu and Muzan had become irreconcilable.

And Muzan's attitude towards me changed; he became exceptionally clingy, and our intimacy level increased.

She started to enjoy physical intimacy with me.

"Are you feeling alright?" Shugo, with a small, gloomy tail, walked into the bedroom filled with the smell of medicine, knelt down beside the bedding, and asked softly.

The black medicine was extremely bitter, and even Muzan, who had drunk too much medicine, couldn't keep his expression straight; his pale face wrinkled up and down.

Muzan was drinking his medicine when he glanced at the two of them.

The two brothers in front of me look remarkably alike, making it easy to tell that they are related by blood.

They are the real brothers.

Is it because of what happened before?

And what is he anyway?

Having faced death once, Muzan's thoughts were extremely calm, as if he had been immersed in ice water.

The medicine seemed to go straight to my heart; it was so bitter.

The child quietly finished drinking the medicine, and the bowl was taken away by the servant.

The sugar ball covered in frosting was then brought to my lips.

Muzan froze for a moment before biting into the candy ball.

The pale pink tip of her tongue touched the white fingertip briefly before separating.

Stroking his curly hair, Shugo pondered Muzan's psychology after surviving such a calamity.

"Ningning, you're amazing to be able to drink so much medicine in one go," Shuugo said in a softer tone.

"And one more thing, Agu."

Shugo looked down at Agu, whose little face was stubborn, his expression serious and full of pressure.

"Yes, I'm sorry, I shouldn't have scared you." Under the intimidating gaze of Shugo, Agu awkwardly stammered his apology.

After saying that, Agu wished he could bury his head in the floor.

Children also have self-esteem.

Muzan stopped crunching on the candy ball, turned his head away, and refused to look at the two of them.

The atmosphere froze for a moment.

“Nene, it’s okay if you don’t want to forgive Agu. Agu apologized because he did something wrong, but not all wrongdoings can be forgiven without question,” Shugo said, emphasizing each word.

If Shugo were in his shoes, and someone had put him on the verge of death, he would definitely want to kill the person who did it.

“Agu, people have to pay the price for their actions. Next time you do something, you should also consider the consequences and whether you can bear them.”

Shugo's tone was stern. To put it bluntly, if fate were to take a turn for the worse, Agu would have to bear the consequences of a life.

Even in ancient times, when human life was treated with utter disregard, a young child should not be allowed to become a murderer.

“Agu, come here. Ningning, slap him with all your might.”

Agu's eyes widened, revealing an expression of disbelief.

Brother, you are my brother, how could you let this outsider hit me?

Still going all out?

Shock and grievance overwhelmed his feelings of regret and fear. Just as Agu was about to resist, he was suppressed by Shugo.

Muzan, who had initially wanted to have a cold war because the other party had brought Agu, the culprit, around, turned around and looked over with an eager expression on his face.

The desire for revenge churned within him, and his unusually cold gaze fixed on the attempted murderer.

"Snapped--"

After the crisp sound, a small handprint was left on Agu's face.

The child's face is delicate; this handprint will probably stay for a while.

Muzan felt the joy of avenging his great enemy, especially the humiliated expression on his enemy's face, which pleased him greatly.

Agu ran away in humiliation.

Hiiragi didn't stop the other party, but simply ordered his men to follow.

Let the child lick their wound.

It's just a slap, which is better than being held a grudge in the future and being harassed by the progenitor of demons. That would be a real living hell.

Hiiragi thought to himself.

Shugo had no doubt whether Muzan Kibutsuji held a grudge or not.

There are no villains and no grudges.

The three thugs in the alley proved this with their lives.

Seeing Muzan's displeasure at being beaten back, Shugo had a headache.

One is struggling to survive on the brink of life and death, while the other was merely slapped in the face; they can hardly be considered equal.

"It just came out recently, so I sent it over to you first." Shugo said something that Muzan wanted to hear.

Hiiragi unwrapped the gifts he had brought.

Considering that Muzan might be bored while recuperating, Shugo sent over the toys he had made before.

It is an animal plush toy filled with expensive silk floss.

Muzan turned her head away, refusing to look at him, her lips forming a cold, sharp curve.

One slap is not enough!

Even if you give me a gift, it won't work!

"From now on, I'll only give them to you, okay? You have things that Agu won't have." Shugo gave his condition.

Muzan finally turned around to look at the new toy.

"Why are they all cats?" Muzan couldn't help but exclaim as he looked at the toys' appearance.

"Because I like cats, and Ningning is also like a bad-tempered cat." Shugo rubbed his head.

"Don't provoke Agu anymore." Shugo gave Muzan a deep look.

Muzan paused, still holding the doll, and stubbornly retorted, "I didn't provoke him on purpose; it's all Agu's fault."

He spoke with such confidence and conviction!

The future boss's style of avoiding internal strife and shirking responsibility is already beginning to take shape.

Shugo didn't say anything, he just patted his little head, and didn't intend to refute.

Muzan secretly glanced at Shugo's expression.

Has it been discovered or not?

"Give Agu a lesson for his personality."

Agumoto is a typical aristocrat, spoiled, willful, and quite self-centered. He is arrogant and rude to those below him, just like Muzan Kibutsuji.

He also didn't want his younger brother to grow up to be a spoiled, arrogant nobleman who bullies others and oppresses women.

I also don't want Muzan to end up like this.

“You won’t be able to eat sweets for the next month. It’s a good time to recover,” Hiiragi said leisurely.

Muzan froze for a moment, then let out a sharp scream.
