early morning.

Inside a dilapidated wooden house.

Nezuko was sleeping quietly in the bed.

She has been sleeping for two years since Tanjiro brought her here.

If she wasn't still breathing, even her brother Tanjiro would suspect that she was dead.

The sleeping Nezuko is not far away.

Tanjiro knelt down respectfully in front of Xuanhao, who was disguised as 'Rin Taki Sakonji', and listened carefully to the teacher's last instructions before he left.

"According to the current intelligence of the Demon Slayer Squad, there is only one ghost in the world who can use his own blood to turn humans into ghosts. You should know who I am referring to, right?" Xuan Hao asked in a deep voice.

"Is this the ghost king you mentioned before, Muzan Kibutsuji?" Tanjiro's expression became a little solemn when the teacher mentioned this matter again.

"Yes, Tsuji Muzan was the first person to become a ghost more than a thousand years ago. He is the enemy who killed your family. He may also be the key to turning Nezuko back into a human." Xuan Hao said,

"Currently, humans have not yet mastered a method that can restore humans who have turned into ghosts to their original state, but if it were Ghost King Muzan Onibatsuji, he might know something."

"Teacher, what you're saying is...if I want to help Nezuko turn back into a human, do I have to find Muzan Kibutsuji?"

"Yes, this is one of the tasks I want to give you."

Xuan Hao nodded lightly, "However, Ghost Dance Tsuji Muzan has been hiding for a long time, and it won't be that easy to find him..."

"Kibutsuji Mumei is the strongest ghost in the world and the source of ghosts. As long as you kill him, ghosts will no longer appear in this world. But even if you find him, you may not be able to do so with your current strength."

He will be his opponent, so be careful, understand?"

"I understand, teacher!"

Tanjiro's face was full of seriousness, "I will definitely find a way to turn Nezuko back into a human, so I will definitely find Kibutsuji Muzan!"

Whether it is for the sake of his deceased family members or to prevent more people from suffering the same fate as himself, Tanjiro believes that he must find a way to turn humans back into ghosts and must find a way to kill this ghost king.

"That's good." Xuan Hao nodded slowly, looking at the determined young man in front of him with some relief, "Now you can leave here and go to Tengxi Mountain to participate in the 'final selection'."

"Yes, teacher! It's just..."

As he spoke, Tanjiro turned his gaze to Nezuko, who was still unconscious.

Nezuko has been sleeping here for two years. As an older brother, it is impossible not to worry. It was only because the teacher kept comforting him that Nezuko would be fine, that he could concentrate on training.

"Don't worry."

Noticing Tanjiro's gaze, Xuanhao also cast his gaze on Nezuko, and his gaze under the mask became much softer.

"Nezuko is different from ordinary ghosts. In her current state, she should be using sleep instead of eating human flesh and blood to restore her physical strength. You must know that ordinary ghosts will fall into a trap if they do not eat human flesh and blood for two years.

In a state of madness.”

"Is that so?"

The worry on Tanjiro's face dissipated a little. He now fully trusts the teacher's words, "Then... Nezuko will temporarily trouble the teacher. After passing the 'final selection', I will be back soon."

!”

"No trouble, no trouble."

Xuanhao gently knocked on Tanjiro's head, making a crisp sound.

This young man's head... is not ordinary.

"I have been taking care of Nezuko for nearly two years. Don't worry, go ahead."

"Ah! Okay, teacher!"

Tanjiro covered his head which hurt a little from the knock.

After Tanjiro left with the Nichirin Sword, Xuanhao focused his attention on Nezuko, who was sleeping beside him.

"What should we do next?"

He looked at Nezuko with a headache.

With Tanjiro's ability to be close to Hashira, he has no worries about what will happen when he participates in the final selection. But the most critical issue now is Nezuko.

In the past two years, he has also tried to find a way to turn Nezuko back into a human, but unfortunately he has not been able to find any way.

After the innocent blood is injected into the human body, it will cause the cells in the human body to mutate. Mutation is not damage. What is needed is remodeling rather than repair. Therefore, even if Xuan Hao wants to repair it with the power he currently has, it will have no effect at all.

As for other methods, such as using his blood to change the blood vessels in Nezuko's body, it's not like he hasn't thought about it, but the risk is too high. No one knows what kind of chemical reaction the ghost will cause after receiving his blood.

', there is no way he would risk Nezuko.

And even though it is impossible for Wuhan to monitor every move of every ghost, if someone wants to interfere with a certain ghost's bloodline, Wuhan cannot detect it.

"So we can only ignore it for now? But..."

Xuan Hao's brows furrowed more and more tightly.

Because if Nezuko cannot be turned back into a human, he will be helpless even if he finds Muzan Kibutsuji.

Wu Kai is the source of ghosts. If Wu Kai dies, the ghosts that have received Wu Kai's blood will also disappear. This is the most troublesome part.

"No matter what, we have to find a way to get Nezuko out of Muzan's control first..."

Xuanhao recalled whether there was any way to free ghosts from Wuhan's control.

Finally, he remembered a special ghost - Zhu Shi.

Although he didn't know if Zhu Shi was still alive after five hundred years, he clearly remembered that Zhu Shi had indeed escaped from Wu Mei's control through unexpected circumstances.

He remembered that the condition for Zhu Shi to escape Wu Mei's control seemed to be because Wu Mei was severely injured by Ji Guoyuan and was seriously injured and weak!

And if Zhu Shi is still alive in the world now, after so many years, maybe she will have other ways to get rid of Wu Mei's control...

"Looks like I have to find her again."

After sorting out his thoughts, Xuan Hao decided to meet the ghost named Zhu Shi again.

But now it was obvious that he couldn't leave here. Tanjiro hadn't come back yet, and Nezuko was in a coma. He had to stay and take care of Nezuko for the time being.

"Let's wait until Tanjiro comes back..."

"Dong-dong-dong-"

Just as Xuanhao was thinking, the door of the wooden house was lightly knocked.

"Dong-dong-dong-"

As if out of politeness, the other party knocked on the door very regularly, and such a wooden door could be pushed open easily.

Xuanhao frowned and looked in the direction of the door, "Yuyashiki? What are you doing here at this time?"

Even without opening the door, he could clearly sense the identity of the person coming outside.

There are three people in total.

Riding a carriage.

The people in the carriage were Ubuyashiki Yōya and his wife Ubuyashiki Amane, who was accompanying him to take care of him.

Because it was daytime, there were no Demon Slayer swordsmen as guards, only a hidden driver.

Yin knocked on the door very politely, but there was no response for a long time. He thought it was because there was no one in the room.

"Okay, no need to knock anymore."

Ubuyashiki Yōya got down from the carriage with some difficulty with the support of his wife.

"Yes." After receiving Uyashiki's order, Yin stepped aside respectfully.

Ubuya Shiki Yaoya slowly walked to the door of the wooden house with the support of his wife.

"Mr. Xuanhao, I have the liberty to ask for a meeting with you, Utsuya Shiki Yaozai."

He stood respectfully at the door waiting for the response from the people in the room.

Yin on the side looked at his lord's respectful behavior with some surprise. He remembered that no one in the Demon Slayer Squad seemed to be able to make his lord so respectful?

On the side, Ubuya Shiki Amane seemed to have known about this for a long time, but she also supported her husband respectfully and saluted the closed wooden door.

"Why are you here?"

Xuanhao opened the door and looked at Yoya Shiki, who needed help even to stand.

He didn't understand why Uyashiki Yōya came here.

This man is seriously ill and probably doesn't have long to live. As the spiritual leader of the Demon Slayer Corps, what this man should do now is to rest in the mansion and try to live longer so that he can better lead the ghosts.

Kill the team in battle.

If you have anything to do, you can send the message directly through Wei Ya. There is no need to travel all the way to visit in person.

"Mr. Xuanhao, can you let me in and talk again?"

Ubuyashiki Yōya smiled at the man in front of him. He could no longer see him, but he could feel that there was a person standing in front of him and blocking the way.

As for why Xuanhao blocked the door to prevent them from entering, he had already heard about it from Rin Taki Sakonji.

"Okay, but the two of them have to stay outside."
