Demon Slayer: The Demon King is actually a weak girl?!

Sun Breathing is the "ancestor" of all breathing methods and was created by Kuniyoshi.

Yoichi Tsugikuni is the twin brother of Kokushibo, and the object of Kokushibo's lifelong pursuit.

Back then, Kokushibo always thought that he was no match for Tsugakuni Yoriichi. For example, he had not learned Tsugakuni Yoriichi's Sun Breathing, and could only modify Yoriichi's breathing method according to his own characteristics and named it "Moon Breathing".

This is also one of the reasons why Kokushibo's defense was broken.

Muzan, who had read novels in her previous life, naturally knew all these things, but she would not say as gently as Kujo Shiozuki, such words as "The moon is also unique", which were picked up from somewhere on the Internet.

She just wanted to break his defense.

She just wanted to piss him off to death.

Who wants him to play her?

"Kuroshibo, the person you wanted to surpass is already dead, do you think you are the strongest swordsman?" Muzan raised his chin with contempt, his veil-like eyelashes hiding the calculation in his eyes, "I will learn the Breathing of the Sun and stand at the top, becoming an existence that surpasses Yoriichi Tsugakuni! And you, huh..."

Muzan recalled the speechless incident in his previous life when Kokushibo was "killed ugly" by him.

Originally, Kokushibo was fighting with those guys from the Demon Slayer Corps in full swing, and he had also broken the beheading limit like himself and Akaza. However, he did not expect that guy would accidentally see his own newly grown hideous head in the reflection of someone else's broken sword, and then began to doubt himself, deny himself, and finally go towards self-destruction.

What a bizarre death!

Of course, Muzan knew it in his heart, that was because the author set the upper ranks to be too powerful and ridiculous, and the setting of the Demon Slayer Corps was too weak. After all, how can flesh and blood defeat monsters with cheats? The only way was to force the monsters to go offline.

But when I think about it, I still get angry. After all, Kokushibo played him in two lives, two lives!

——Then let him get angry too.

Veins bulged on his body, Kokushibo clenched his fists, and his six eyes were filled with resentment and confusion.

He didn't understand that Lord Muzan had always been cooperative with him. It had been like this since Muzan tried to win him over.

But why did she anger herself now? Why did she say such words...

——There is no doubt that Muzan controlled him through his blood, and he had no way to defeat Muzan.

"Yes……"

Just as one word came out of his mouth, he was holding it in his throat.

——He is unwilling!

Muzan said she wanted to learn the Breathing of the Sun, how is that possible?

The Breathing of the Sun has clearly been lost...

"It's impossible... She can't possibly learn it."

Comforting himself in this way, Kokushibo slowly felt at ease.

"Yes, Lord Muzan." He said in a deep voice.

Muzan narrowed his eyes: "'It's impossible, she can't learn it'? How dare you think that?"

“……”Oh no, Lord Muzan can hear my inner thoughts. Kokushibo was really careless.

But he had heard it all, so he couldn't argue, and could only tell the truth: "I have nothing to say. The Breathing of the Sun has been lost, and it is very difficult. Besides, there is no need for you to learn it."

"As long as I can't learn it, you will always be the strongest swordsman, right?" Muzan smiled sinisterly, "Practice well. The Sun Breathing has not been lost, but has become a kind of dance. The user doesn't know what it is. Oh, by the way..."

Muzan tapped the tip of the man's nose with his slender fingers and winked at Kokushibo slyly, "Don't forget, you can't eat humans."

After she said all this, she went to Nightmare, and the two of them disappeared on the spot with the sound of the pipa.

Kokushibo was stunned, and the touch just now seemed to still leave some warmth on the tip of his nose.

He had no idea what was going on with Muzan.

"What does Lord Muzan mean by this? Do you want me to learn the Breathing of the Sun? But isn't that what she hates and fears the most?"

Moreover, it was also what he hated the most...

——No, actually he longed for it, but it was something that he could never achieve in his extremely short life.

"The only one who can reach there is..."

Whenever he thought of someone, Kokushibo felt that he could not calm down.

"Yes, since I can't get it, I'll just destroy it."

He longed for it and also hated it.

Why did Muzan want to dig out something that should have been forgotten for a short time? He even said that he wanted to learn that rare and bizarre thing...

Lord Muzan...what on earth are you thinking about?
