Chapter 31: Muzan who forgot the pain after the scar healed

Did I draw the gender backward?

After Muzan Kibutsuji entered the Infinity Castle, he looked at his buttocks that had been blown to pieces, and there was still a strong stinging burning sensation on it.

This made him feel a sense of humiliation, and a burst of anger suddenly ignited in his heart! He wished he could tear Zero into pieces!

And those small missiles not only blew up Muzan Kibutsuji's buttocks, but also destroyed a large area of the houses around him.

"This damn demon slayer! I will never let you go!" Muzan Kibutsuji thought fiercely in his heart, then controlled the tube whips behind him to cut open the burning part of his buttocks and completed rapid regeneration!

"Where exactly did that demon slayer come from? Why does he have so many strange weapons!?"

This made Muzan Kibutsuji a bit confused, but what he cared more about was what Zero had said—that his age was not even half of his, so in that way, Zero was at least a person who had lived for more than two thousand years!?

"Can humans really live for so long?" Muzan Kibutsuji thought to himself.

It seemed very absurd, but for some reason, he always felt that the demon slayer hadn't lied! His intuition was also constantly responding to Muzan Kibutsuji: this is true!

"If I devour this demon slayer, can I become the same as him?! No, turning him into a demon is more appropriate. Then I only need to read his memory to know what this secret is?! Hehe... Hahahaha...!!"

Muzan Kibutsuji felt that he seemed to have grasped some shocking secret, completely forgetting what had just happened!

If Zero knew what Muzan Kibutsuji was thinking now, he would definitely verify his previous guess again: his IQ is worrying!

Five brains share the IQ, and he forgot the pain after the scar healed!

"That's how it is, but having said that, Giyu, how did you know there were evil demons here?"

Zero and Giyu Tomioka and Tanjiro and the others returned to the house and told the general story.

And Nezuko was lying on Zero's lap wearing his cloak and hood, looking drowsy and wanting to sleep.

Tanjiro was comforting Takeo and the other three.

"It was Grandpa Saburo who told me." Giyu Tomioka said.

"Saburo?" Zero was a bit confused; he didn't know who the Saburo that Giyu Tomioka mentioned was?

"Master, Saburo is the name of the Water Hashira's Messenger Crow, he is an old senior among our Messenger Crows!" The Messenger Crow, Yuki, on the side explained.

After Yuki's explanation, Zero finally understood who the Saburo Giyu Tomioka mentioned was; it turned out to be his Messenger Crow.

Looking at the Messenger Crow beside Giyu Tomioka, it was already a bit old. No wonder Yuki would say that Saburo was an old senior among the Messenger Crows.

But thinking about it, Giyu Tomioka was not good with words, so he probably couldn't get along with other Messenger Crows, and Saburo, as an old senior among the Messenger Crows, had seen a lot, so naturally, he understood more.

"Lord Zero Hashira." The old voice of the Messenger Crow, Saburo, came over.

"Thank you for being willing to get along with Giyu, this child is just not good with words, so every time he speaks, it is easy to be misunderstood! If there is anything wrong, I apologize to you on his behalf!"

The Messenger Crow, Saburo, always thought about Giyu Tomioka in everything he said, but because of his old age, he was already powerless.

Zero: "Hmm, don't worry, I will."

Messenger Crow, Saburo: "Thank you."

Next was waiting for Rokuta and Kie's treatment to end. Since it would take a few hours, and he didn't know what to do, Zero began to consider how to settle Tanjiro's family.

He had thought about this before, and he intended to arrange for Tanjiro's family to stay in the Demon Slayer Corps first, living in his mansion.

But without the consent of the leader of the Demon Slayer Corps, Kagaya Ubuyashiki, he didn't know if it would work?

Even if it worked, with the personalities of those Hashira in the Demon Slayer Corps, Nezuko becoming a demon would probably be even more inappropriate.

Especially Sanemi Shinazugawa, who was not only irritable but also full of malice toward evil demons, wishing he could kill all evil demons!

Once brought to the Demon Slayer Corps headquarters, it wouldn't be long before it was discovered, and then Nezuko would be pushed to a dead end!

Even if Nezuko didn't eat humans, it was the same!

Moreover, although Nezuko had broken free from Muzan Kibutsuji's control, how could he guarantee that it was completely broken free or just temporarily broken free?

If it was temporary, then the location of the Demon Slayer Corps headquarters would definitely be exposed. At that time, Muzan Kibutsuji would probably come to the door, and that would definitely be a bloody and fierce battle!

"Sigh~ what exactly should I do?"

Just as Zero was thinking and trying to find a way, Tanjiro appeared on the side and interrupted his train of thought.

Tanjiro: "Brother Zero."

Zero: "Hmm? What's wrong, Tanjiro?"

Tanjiro knelt down, put his hands in front, and said: "Brother Zero, please teach me to become stronger! I... I want to become stronger, protect my family, and find a way to turn Nezuko back into a human!"

This was also the method Tanjiro decided on after careful consideration.

After this incident, plus what Giyu Tomioka said just now, Tanjiro deeply realized his own weakness.

Therefore, he wanted to ask Zero to teach him to become stronger, so that he could protect his family and find a way to turn Nezuko back into a human at the same time.

"This... sigh, Tanjiro, do you really want to do this?"

"Yes, Brother Zero, I am sure!"

"Alright, get up first!"

Tanjiro raised his head and sat up straight, waiting for Zero's reply.

Zero didn't know what to do now either. After all, he was different from those people in the Demon Slayer Corps; he didn't know Breathing Techniques, but relied on his own thousands of years of combat experience and skills, as well as the weapons he created to kill evil demons.

And his training method was also extremely arduous; even the Hashira of the Demon Slayer Corps might not be able to bear it!

Simply, he looked at Giyu Tomioka to see if he had any ideas?

Seeing this, Giyu Tomioka thought about it and immediately gave an answer, saying to Tanjiro: "Go to the foot of Mount Sagiri and visit an old man who lives there named Sakonji Urokodaki."

"Just say that Giyu Tomioka told you to come. If possible, take your sister with you! Also, try not to expose your sister to the sunlight; demons cannot see the sunlight."

Giyu Tomioka let Tanjiro take Nezuko, who had become a demon, with him because he felt that this pair of siblings was different.

He had encountered such situations before, and those people had said the same thing, but the ending was that they all died!

Evil demons in a "starving state" would even kill and eat their parents, brothers, and sisters, because the flesh and blood of humans had high nutritional value for evil demons!

Up to now, Giyu Tomioka had seen such scenes I don't know how many times...

But just now, Nezuko, who was a demon, not only maintained her desire not to eat humans but also used her body to block in front of Giyu Tomioka to protect Zero and Tanjiro and the others behind her.

Hearing the reply, Tanjiro immediately became excited and replied: "Yes! Mr. Tomioka, thank you! And thank you, Brother Zero!"

Seeing this, Giyu Tomioka was also ready to get up and leave, but Zero called him to stop.

"Giyu, wait a moment!"

"What's the matter?"

"This matter is a long story, I'll tell you later. After you return to the Demon Slayer Corps, don't tell anyone for now! There are still many places I haven't figured out. After I handle it, I will personally return to the Demon Slayer Corps to explain the situation."

"Hmm, I know." Giyu Tomioka said, his figure flashed, and he disappeared in place.

However, not long after, Giyu Tomioka appeared in front of everyone again and handed something in his hand to Zero.

"What is this?" Zero took the thing Giyu Tomioka gave him; it was a muzzle made of small green bamboo, with red ropes connected at both ends.

"For her!" Giyu Tomioka pointed at Nezuko, and then his figure disappeared again.

Zero smiled helplessly, put the muzzle on Nezuko's mouth, and tied it for her himself.

Nezuko like this looked quite cute.

Afterward, he took out his pen and notebook and wrote a personal letter, folded it, and tied it to the leg of the Messenger Crow, Yuki.

"Yuki, please help me deliver this letter to the Master, I will wait here for you to come back. Also, don't report the incident of me meeting Muzan Kibutsuji and fighting him for now! Do you understand?"

"Understand, Master!" Although the Messenger Crow, Yuki, didn't know why its master didn't let it report, it wouldn't ask; it would do whatever Zero told it to do.

Finally, it flapped its wings and headed toward the Demon Slayer Corps headquarters.

Watching the figure of the Messenger Crow, Yuki, flying away, Zero fell into deep thought again. He now wanted to figure out one thing.

That was about that strange sound of the koto.

More than a year ago, when he hadn't joined the Demon Slayer Corps yet, he encountered Upper Moon Two—Doma, who was fighting Kanae Butterfly.

After saving Kanae Butterfly, he also fought Doma, but at the last critical moment, that strange koto sound rang out, and a wooden door appeared to save Doma, who was about to be killed by him!

And last night, it was the same!

It was also at the last moment that a sound of the koto made Muzan Kibutsuji escape.

Whenever that koto sound rang out, a wooden door connecting to other places would appear out of thin air!

Zero guessed that behind that wooden door, it might be Muzan Kibutsuji's lair!

According to this situation, there must be a powerful evil demon who can control space beside Muzan Kibutsuji!

As for whether the specific strength is strong or weak, it is still unknown...

Could it be one of the Upper Moon demons, or is it not an Upper Moon demon, just an ordinary evil demon who can control space?

But no matter what, this evil demon, even if it doesn't have powerful strength, just by being able to control space, is a troublesome guy!

If the Demon Slayer Corps headquarters is discovered, then he only needs to open the wooden door and release all the evil demons, which will be the doomsday of the Demon Slayer Corps!

If he could enter the Infinity Castle, maybe he could analyze the data, but Muzan Kibutsuji's cowardly personality, would he let him enter the Infinity Castle so easily?

Moreover, since it is Muzan Kibutsuji's lair, the Upper Moon demons and Lower Moon demons must all be gathered there, so it is also very troublesome to deal with!

However, what Zero didn't know was that one day later, he did enter the Infinity Castle and almost tore the Infinity Castle apart...

Demon Slayer Corps headquarters.

The Messenger Crow, Yuki, flew for several hours and arrived at the Demon Slayer Corps headquarters. Following Zero's instructions, it came directly to the Ubuyashiki mansion and handed the letter on its leg to Kagaya Ubuyashiki.

Kagaya Ubuyashiki saw the content of the letter, and the more he read, the more shocked he became. He didn't expect Zero to encounter Muzan Kibutsuji!

Not only that, but he also had a battle with him and forced him back!

Calming down his inner heart, he continued to read. The letter also mentioned the hope of arranging the Kamado family in the Demon Slayer Corps headquarters, living in his mansion.

Therefore, he requested to get Kagaya Ubuyashiki's consent, and he could serve as their guarantor...

After Kagaya Ubuyashiki finished reading the content of the letter, he said directly to Amane Ubuyashiki beside him: "Amane, please write a letter to Zero according to what I say. Also, notify the Hashira-level swordsmen to hold an emergency meeting after Zero returns!"

Amane Ubuyashiki: "Yes."

Not long after, Amane Ubuyashiki wrote a letter according to Kagaya Ubuyashiki's instructions and handed it to Zero's Messenger Crow.

Watching the Messenger Crow flying away, Kagaya Ubuyashiki fell into deep thought...

【Treatment countdown: 3... 2... 1...】

【Beep~ Treatment ended】

Following the treatment end prompt of the 【Healing Chamber】, Zero opened the lid, carried Rokuta out, and put on the clothes prepared by Takeo beforehand.

Rokuta also woke up at this time. Seeing Zero, he hugged him tightly.

"Alright, alright, Rokuta, good boy, good boy!" Looking at Rokuta in his arms, Zero gently pinched his little face.

"Brother Zero, my mother's side is also finished!" Hanako shouted in the room.

"Hmm, coming."

Coming into the room, Zero only opened a slit in the lid of the 【Healing Chamber】 and then left.

After all, it is not polite to look.

After a while, Kie Kamado also changed her clothes and walked out of the room with Hanako.

She was wearing a light blue kimono, her hair was disheveled, plus her purple pupils and the beauty mark on the corner of her mouth, she looked quite charming.

Subsequently, Kie Kamado led Tanjiro and the others to kneel in front of Zero, with their hands in front of their heads. This action frightened Zero.

Zero: "Aunt Kie, what are you doing?! Get up quickly. Tanjiro, you all get up quickly too."

Kie Kamado: "Zero, thank you! Thank you for saving my children, and thank you for saving me!"

Zero: "Aunt Kie, you get up first, let's talk properly."

As he said, he helped Kie Kamado up.

"Zero, if it weren't for the thing you gave me before, I'm afraid the children would have really... really... woo..." Kie Kamado said while leaving tears. Recalling what happened last night, she was still very scared.

That monster didn't know what was going on, directly broke in and started a massacre. Their family had never seen this monster before, and didn't understand why he wanted to do this?

If it weren't for the 【Quantum Shield】 that Zero gave Kie Kamado a year ago, I'm afraid they wouldn't have escaped the disaster!

"Aunt Kie, sorry, if I had rushed over earlier, you wouldn't have suffered such a disaster! Nezuko wouldn't have become like this..."

"Zero, please don't say that. If it weren't for you rushing over in time, my children and I would probably not be in this world now... And, no matter what Nezuko becomes, in my heart, she is my child, and this will not change!"

Looking at Nezuko, who was a bit confused in the corner, Kie Kamado felt a sourness in her heart.

"Don't worry, Aunt Kie, I will find a way to turn Nezuko back."

"Thank you, child!"

"Thank you, Brother Zero!"

"Thank you, Brother Zero!"
