I, a Celestial Dragon!

The doctor's treatment actually kept him alive...

Although this kind of living has countless side effects, he needs flesh and blood to continue to survive.

And as his desire for flesh and blood grew, Amaterasu completely rejected him.

He could no longer step into the sunlight.

He became a ghost that could only move at night.

At this moment, Muzan, who had regained his life, had his last regret.

That is what he regrets the most to this day.

He shouldn't have killed that doctor!

He shouldn't have taken the life of the doctor who was treating him when he was in despair!

Muzan, who had encountered a sudden change, went from hating and despising the doctor to missing and trusting the doctor immensely.

He believes that the doctor's treatment of him would be effective if the doctor were still alive and continued to treat him.

Then he can return to the sunshine and have a complete life again!!!

Therefore, Muzan had a second goal in life at that time.

After keeping himself alive, Muzan’s second goal is to find the blue spider lily!

Because the legendary blue spider lily, which is rarely seen in a thousand years, is the main medicine used by doctors to treat Muzan!

However, it would be difficult for him to collect information about the blue spider lily by relying solely on himself.

He was alone and could only go out at night.

It seemed that he was aware of Muzan's need for subordinates.

Or maybe that is the ability that Muzan himself possesses.

In short, not long after, Muzan discovered that his blood could infect other people and turn them into life forms similar to himself.

From then on, demons appeared, and Muzan continued to expand the area of ​​attack, bringing more and more people into the attack range, while spreading his blood madly.

And as Muzan attacked more and more, as he killed and devoured, he also transformed more and more humans.

The curse has come upon Wuzan!

Muzan is becoming more and more afraid of the sunlight!

This curse even spread through Muzan's bloodline to the Ubuyashiki family, to which Muzan belonged during his lifetime.

Ever since Muzan became the ancestor of demons, all the men in the Ubuyashiki family could not live past the age of 26.

Therefore, the Ubuyashiki family and Muzan became completely opposed to each other, and the Demon Slayer Corps came into being under such circumstances.

Ubuyashiki himself was a daimyo in the Kanto region, and his family already had considerable resources.

The doctor who treated Muzan was even able to find blue spider lily, and the Ubuyashiki family, who provided the materials to the doctor, originally had considerable power in Japan.

With them in the lead, the initial scale of the Demon Slayer Corps even far exceeded that of the Demon Slayer Corps in the Taisho era.

From then on, the war between demons and humans was completely launched, and the war between Muzan and his family during his lifetime was completely kicked off.

And just after this curtain lasted for nearly a hundred years.

Tsugikoku Yoshiichi appears...

What kind of demon king was Muzan before he met Yoriichi Tsugikoku?

We can completely regard Muzan at that time as the complete version of Dio.

He has far more subordinates than Dio, and has far more power to suppress the world than Dio.

Kibutsu Kenmu Zan encountering a world without breathing techniques is like Dio encountering a world without wave power and stand users!

What was Muzan's famous saying at that time?

"Consider being killed by me as a great disaster, and don't think too deeply about it.

There were violent storms, volcanic eruptions, and earthquakes.

No matter how many lives the scourge takes, no one will attempt to take revenge on it!

The dead cannot be brought back to life, so stop dwelling on something that cannot be undone.

Earning money steadily and living peacefully, that's enough!"

That's right!

At that time, Muzan's thoughts were even more advanced than Dio's.

At the peak of his powers, DIO only defined himself as evil itself, the dark side of the world and the savior of evil.

But no tragedy.

He believes that his existence is an indispensable part of nature.

He attacks, he kills.

That's as natural as wind and rain.

In a world without justice or evil, or even life.

The wind will still blow and the rain will still fall.

From this perspective, the life of Muzan, who was once full of vigor and vitality, has really reached its climax.

As a result, just when he was most proud, his life completely collapsed...

At first, after learning that the breathing technique had spread among humans.

Guiwu Qianwuzhan's mentality is relaxed.

A slightly stronger human would only expand Kibutsu Muzan's fun.

As for Tsugakuni Yoshiichi, he had heard of that man, a member of the Demon Slayer Corps who was known to be terrifyingly strong, and a subordinate that his own younger generation, the Ubuyashiki family, relied on particularly.

But what is Yuichiro Tsugikoku?

Tsugikoku Yuichi is a piece of shit!

Even your lord is just my, Kibutsu Muzan's descendant.

The whole world is my ghost dance, so miserable! ! ! !

That’s right, Kibutsu Muzan in his prime is stronger than DIO in his prime.

Because his uncle's family always stands in Dio Brando's way.

But Kibutsuki Muzan has no uncle, and the Ubuyashiki family is not qualified to be Kibutsuki Muzan's uncle!

Until he met Yoriichi Tsugikuni.

ten years……

It's been ten years!

I have been in this gutter for ten years!!!

Since the first time he was chopped to pieces by Jiguo Yuanyi, Guiwu Qian Muzan has understood deeply.

I will never be a match for that guy!

Weak human flesh and blood is no longer enough to make him stronger.

As for the more ghosts he created, they would not be stronger than himself.

There is no one stronger than me, no one!

Therefore, he cannot defeat Yoriichi Tsugakuni now.

There will be no way I can defeat Yoriichi Tsugakuni in the future!

At this moment, Gui Wuqian, who had been hiding for a full ten years, even felt a little aggrieved.

I am a poor guy who cannot live past the age of 20 since I was born.

Even if I was cured, I would also gain eternal life.

I am still a poor person who can't even see the sun again!

I only have two goals. One is to find the blue spider lily, continue to heal myself, and allow myself to bask in the sun again.

The other is to endure the nausea and distribute the blood to more humans to create more ghosts.

He no longer wanted to start more killings, nor did he expect more demons to defeat Yoriichi Tsugikoku, whom even he, Muzan, could not defeat.

What's more, what qualifications do weak humans have to drink his blood?

The reason why he keeps creating ghosts now is just to find a mutant, special ghost that is not afraid of the sun, analyze the reason why this ghost is not afraid of the sun, and then let himself have that ability!!!

I'm so pitiful. Brother, can you please stop chasing my shadow on the street?

I'm so fucking scared that you keep following me like this!

Don't you know how terrible you are!

I am so weak, helpless and pitiful!

Can't you be kind?

You alone have made me afraid to show my face, and yet you found the Lord God from nowhere!!!

Do you really want to kill them all? ! !

"Ahhh, Yunyi, I hate you!!!"

With an extremely angry roar, Guiwu Qianwuzan completely collapsed in his own underground space.

The lord of the gods has always been the righteous god served by the Ubuyashiki family. When the Demon Slayer Corps had no breathing method, the official lord of the gods' protection allowed the Demon Slayer Corps to survive the initial stage.

Nowadays, when most daimyos know the existence of demons, the vast majority of them have become believers of the Shinto.

Neither Kibutsugu Yoshiichi nor the other demons under his command witnessed the battle between Tsugumi Yoshiichi and Takahashi.

But that doesn't mean Wuzan can't see it.

When he arrived in the wild, he sent his cannon fodder to the vicinity of Shinano, killed a farmer who was fortunate enough to witness the scene and turned him into a ghost.

In this way, Muzan, from the perspective of a peasant, witnessed with his own eyes the strength of the peak Tsugakuko Yoriichi, which had already broken the world level, and the even more unreasonable strength of Gawain!!!

"Why is this happening? Why? I just want to become a complete human being!"

Wuzan sighed in pain, wondering why there were always monsters of this and that appearing in the world.

I am not special, I need to hide myself more deeply!!!

Just like that, Muzan, who had already shrunk to the extreme, dug himself a little deeper, and incidentally opened up two more escape routes.

Then...

Including Kokushibo, and every demon under Muzan.

They can no longer contact their boss...

In response to this, Kokushibo's reaction was particularly strong.

Even though ten years have passed, Kokushibo will never get over the hurdle in his heart.

What did he do ten years ago?

In order to survive, he cut off the head of the lord of the Ubuyashiki family and presented it to Muzan Kibutsu.

Then he became a ghost.

As a result, less than a day after Kokushibo turned into a demon, Yoriichi killed Kokushibo's boss in response.

What do you call this?

This is the behavior of those who joined the KMT in 49 and didn’t last long at all!!!

This was not the most frustrating thing for Kokushibo. What really defeated Kokushibo was Muzan's defeat.

Before becoming a demon, Kokushibo's only pursuit was to survive.

After he had a long life, Kokushibo had only one thing left to pursue.

That is to defeat Yoshiichi!!!

After becoming a demon, Kokushibo's Moon Breathing Technique became countless times stronger, and he himself also acquired extremely powerful blood demon technique.
