Demon Progenitor Development Project

After finally managing to coax the person to sleep, Shugo left wearily to investigate the origin of the sword. After a series of interrogations, he came to a conclusion.

That sword was brought by Muzan himself.

Bringed from the Ubuyashiki family.

Ubuyashiki... The image of a gentle and kind old man flashed through Shugo's mind.

Even now, the approachable head of the Ubuyashiki family, Eiji Ubuyashiki, is still awake.

He is over fifty years old and can be considered an old man.

Looking back on his life, Eiji Ubuyashiki felt that he was quite successful.

Aside from the issue of succession, which is causing him some worry.

An heir who is so ill that he could die at any moment cannot provide any sense of security.

However, due to pressure from the Fujiwara Kita family, the heir could not be changed.

He couldn't afford the price.

However, he also raised another healthy son.

Tsukihiko was simply unable to handle the family affairs, so finding someone else to assist him became inevitable, and Fujiwara Shugo was unable to stop it.

However, Tsukihiko is currently seriously ill, and if his son dies, the support from the Fujiwara Kita family will definitely decrease significantly.

Most importantly, his son had no offspring and could not inherit his political assets.

The old man, deep in thought, made a decision: to fulfill the marriage agreement.

-

The next morning, Muzan woke up and hugged the human-shaped body pillow in his arms tightly, as if he wanted to shrink himself into a ball and hide in Shugo's arms.

Shugo looked haggard and hadn't slept all night; he could imagine it.

What kind of rumors will circulate about their relationship?

Faced with Muzan's current state, Shugo had no choice but to appease him and apply to work from home.

It's been like this for several days in a row.

Being clung to like an octopus makes working much more difficult.

Over the course of several days, I didn't get any work done; I just spent all my time taking care of Muzan.

Muzan, whose emotions were in turmoil, was immediately given a critical condition notice by the doctor.

Shugo didn't care about the backlog of official duties; it was only a few days and no one would rush him.

The efficiency of office work during the Heian period was truly remarkable.

However, adjusting Muzan's current mental state is now an urgent matter.

After such a long time, Muzan, who had finally stopped trembling, was able to understand human speech a little better.

Shugo carefully tended to the man, who was so thin he was practically skin and bones, and coaxed him in a low voice, "Take good care of yourself. I'll be back tomorrow. I have to participate in a hunting event organized by the Genji tomorrow morning, so I might not be back for a few days. I'll bring you a present then..."

After rambling on and on, Muzan curled up in the warm bedding, looking like a lump of dead flesh. His voice was barely audible, and he held onto Shugo's hand tightly, repeatedly confirming Shugo's promise.

"...If I don't come back, I won't pet the cat anymore, and I'll give it to someone else." With no other choice, Shugo made this promise with a heavy heart.

After a slow, deliberate thought, Muzan reluctantly let go, barely managing to trust Shugo.

This shows just how deeply ingrained Shugo's cat-loving persona is in people's minds.

Shugo was too exhausted to even complain, and hurriedly left to deal with the mountain of official business and the overwhelming public opinion.

A few days later, Ubuyashiki Eiji arrived at the bedroom where Muzan was temporarily staying.

The timing was perfect; Hara Shugo had just left, and Muzan hadn't rested yet.

He waved his hand, signaling the servants to step aside for the time being.

As Eiji Ubuyashiki looked at his son, who had changed so much, his worry grew stronger.

Muzan looks like he's not far from death.

"...Fulfill the marriage agreement?"

Muzan didn't react to what his own father had said for a long time, and just stared at his father blankly.

Even with a mind clouded by illness, it still felt incredible.

If he were to fulfill his duties as a husband in this condition, he would probably die on the spot in bed.

Will the marriage produce offspring?

Have you given up on me?

Are you absolutely certain I will die?

So you want me to have offspring?

Completely hitting a nerve, Muzan stared at his own father with an extremely gloomy look, like a sharp knife that would stab someone until they bled, making Ubuyashiki Eiji's whole body tremble with fear.

Ubuyashiki, who couldn't help but shift her gaze, was taken aback.

Given Muzan's serious illness and the father-son relationship between the two, no formal hospitality was served.

Muzan met his father while lying in his hospital bed.

Upon hearing these words, Muzan's thin hands gripped the bedsheets tightly, veins bulging, but that wasn't the point.

Muzan's fingernails were growing strangely, shimmering with an eerie blue-purple hue, and were as sharp as the claws of a wild beast.

The quilt, covered in fine stitches, had been pierced, but Muzan was completely unaware.

Ubuyashiki Eiji broke out in a cold sweat.

Is this his son?

Although belief in ghosts and spirits is very popular in Heian-kyo, the extent to which one believes in them depends entirely on the individual.

Eiji Ubuyashiki happened to be one of those who were half-believing and half-doubting.

After managing to say a few perfunctory words and making polite remarks, Ubuyashiki Eiji quickly left.

The old man ran away as fast as he could.

The old man ran away, leaving his resentful son behind.

"Lord Tsukihiko, it's time for your treatment," the maid supporting Muzan said tremblingly.

Muzan, whose aura was like that of a vengeful ghost, said nothing, but his sinister and vicious gaze swept over the maid's entire body, like a venomous snake about to spray poison.

Seeing the medicine bowl on the plate, the enraged Muzan overturned the table, spilling the black medicine all over the floor.

Maid (strong): Another job added to my workload.

Muzan's curses were incessant, and his fear grew daily in response.

The maid carefully tidied up the broken pieces.

"Get out of here right now!" came a shout.

The maidservant lowered her head and obediently replied, "Yes."

Muzan's only kind gestures were reserved for Fujiwara no Shugo.

Being indifferent to others is considered mild.

They treated servants who were not considered "human" with beatings and verbal abuse, venting their fear to the fullest.

Therefore, all the servants who served Muzan eagerly awaited the arrival of Lord Shugo every day.

Not only will this calm Muzan down, but Shugo will also give these servants an extra sum of money to appease their resentment.

After Muzan's emotions fluctuated wildly, a servant went to inform the doctors.

The arrival of several doctors forced Muzan to suppress his temper.

After the doctor examined the patient, they discussed the patient's condition in hushed tones.

A child comes to have his blood drawn as is customary.

In ancient times, there were no syringes, so people had to use sterilized knives and silver needles to create wounds and obtain samples.

This was Hiiragi's private instruction.

The doctors were impressed but didn't understand, so they didn't object.

Crimson blood dripped slowly from the wound into the container below.

?

The boy looked at the blood that had stopped dripping and became puzzled. Having practiced many times, he knew that the wound was cut just right. How could it not be enough?

When the child examined the wound, he was surprised to find that it seemed to have healed a little.

Remembering the patriarch's instructions, the child silently inflicted wounds again.

After collecting the blood, the child got up and left nimbly.

We must inform Lord Shugo of this matter.
