Uchiha's Blade

Mana felt that she couldn't understand the thoughts of people in this world.

She couldn't understand why Tomioka Giyu was so angry!

If Mana felt that she had done something to make Tomioka Giyu hate him at first, the subsequent development seemed to be different.

Tomioka Giyuu did not come to her angrily and scold her, but began to practice hard, as if he was trying to improve his strength.

And when the two met one time, they firmly expressed their determination not to be held back next time.

Mana: "..."

I can’t understand this brain circuit at all!

If you don't understand it, you have to put it aside in advance.

For Mana, the most important thing at the moment is to study the sacrifice for the reincarnation of the dirty land.

The day Mana came back after snatching Heishimou's sword, the news spread throughout the upper echelons of the Demon Slayer Corps.

At least Uyashiki Yōya already knew what happened.

As for the handling of this knife, Ubuyashiki Yōya also listened to Mana's opinions.

"I need to study this knife. It is impossible for a normal knife to have eyes. If the guess is correct, this should be some kind of vampire technique, or it may be a part of Hei Shimo's body. After all, he has the most The striking feature is the six eyes, and the knife is also full of eyes.”

Ubuyashiki Yōya asked: "Can we deduce his weakness from this?"

Based on the reports of Tomioka Giyu and Mana, as well as the description of the Black Death Mou's strength, Ubuyashiki Yoshiya feels that if this encounter is not Mana who can fly the Thunder God Jutsu, but other pillars, it is very likely that he will Killed by Black Death Mou.

The demon, one of the upper strings, indeed has a strength that far exceeds that of Hashira.

Zhenna said: "Actually, there are two main reasons why I want to study him."

The first, of course, is the ghost's ability to recover quickly.

Mana roughly explained the art of reincarnation and said: "That's it. I cannot accept the use of innocent living people as sacrifices, but the sacrifices required for reincarnation do not necessarily have to be 'complete people'. As long as the conditions for sacrifice are met, it is possible to cultivate it in a laboratory."

Before Mana crossed over, Senju Tobirama was already conducting relevant research, but until Mana crossed over, the research did not make effective progress.

The basis of Senju Tobirama's research is Senju Hashirama's wood escape cells.

Considering that people in this world are obviously not adaptable to chakra, Mana feels that the effect of using wood escape cells is probably not very good.

...even though she does still have wood escape cells in her hands.

Fortunately, this world is not adaptable to chakra, but it also has 'local specialties' with strong vitality. Unless it is basking in the sun or being beheaded by a nichirin knife, it will not die even if it is cut into 800 yuan. ghost.

This is a magical physique that even Senju Hashirama does not have!

Mana decided to do research from the ghost's perspective.

After all, ghosts are also transformed by people, so it should be used as a reference to some extent.

"If everything goes well, we should be able to cultivate sacrifices for use in the research room."

Ubuyashiki Yoshiya said: "Isn't this a bit disrespectful to our ancestors?"

Mana said: "Be open-minded, Teacher Yaoya, if it's you, as long as you can contribute to killing Muzan, I don't think you care about being disturbed after death."

Ubuyashiki Yoshiya said: "Of course it doesn't matter to me, but those team members... no matter what, this technique is too contrary to human ethics."

Mana was silent.

Of course she knows that.

To a certain extent, the reincarnation of the dirty land is indeed a technique that plays with the dead and subverts life and death.

No matter how good the reason is, the most important point that cannot be ignored is that even if the target reincarnated by the foul soil is unwilling to obey the order of the caster, the caster can still control the target through the spell buried in the body of the foul soil reincarnation.

Ubuyashiki Yōya said: "Mana, please conduct this research in secret. I don't want to use this technique unless necessary."

Of course, he is not so pedantic that even if he is facing a desperate situation, he will never use this technique that can subvert the situation.

No matter what, the lives of the living are always more important than the feelings of the dead.

Therefore, Ubuyashiki Yōya did not blame Mana for digging Stepkuni Enichi's grave. As the leader of the Demon Slayer Squad, he still had this clear understanding.

After coughing twice, Uyashiki Yoshiya said: "Tell me about your second reason."

Mana sighed: "The second reason is Nezuko. I promised to heal her arm, but Kibutsuji Mukai's blood is indeed very overbearing. I took out the sealed arm before, and it was less than 1 I was so scared that I hurriedly sealed it back in minutes. Even if it was suppressed with medical ninjutsu, Kibutsuji Mumei's blood would completely erode Nezuko's arm within half an hour. But at the moment, the only material available in my hand is Nezuko's hand. That’s all, this time I got part of one of the upper strings, and together with the ghosts at Fujisei Mountain Pass, I think it should be able to help me lock in the power of Muzan Kibutsuji, and try to suppress and separate it.”

As one of the upper strings, Heishimou's strength far exceeds the ordinary ghosts on Fujirai Mountain, and the concentration of Kibutsuji Mumei's blood he possesses is also far higher than those ghosts. This is indeed a good material for research.

Ubuyashiki Yōya thought for a while and asked: "If the experiment on Nezuko Kamado is successful, is there any hope of developing a medicine that can turn ghosts back into humans? There are also many people who do not actively want to become ghosts. If you encounter ghosts that can eat people in the future, can you try to help them?"

In the past, even if the Demon Slayer Corps encountered such a miserable ghost, they could only cut off the ghost's head in a painless way because they had not had time to eat people, but if it could be cured...

Mana thought for a while: "This is an idea, but I can't give an answer yet. I know too little about Muzan and Oni. Recently, although I have read the information that Miss Shinobu left for me with my shadow clone. There is still a long way to go before we can truly integrate it.”

Ubuyashiki Yoshiya said: "Don't force yourself too much."

Mana said: "It doesn't matter, I want to cure Nezuko anyway."

The Kamado family are very good people. They saved Mana who was seriously injured and was living in the heavy snow. However, Mana felt that she failed to protect them, so she always felt a little guilty in her heart. If she could cure Nezuko, that would be great. But that's it.

Ubuyashiki Yoshiya said: "The burden on you will be too heavy. Originally, the trainers will be coming in a while, and this year's final selection will also be held. I originally wanted you to preside over it. Now it seems that I have to find other candidates. What do you think of Muichiro? Although he is still young, I think he can be trained more."

Mana: "Let me tell you one thing. Muichiro still hasn't been able to remember my name. It seems a little bit to put him in charge of this matter... I think Mr. Tomioka should try it. Don't you also say that Tomioka is responsible for this matter?" Does Mr. Oka seem to have some knots in his heart? It might be of some use to let him meet those young and enthusiastic children."

Ubuyashiki Yōya nodded: "I understand, I will talk to Giyu about this matter. In addition, the hidden troops reported that the new wisteria field you want has been built. It is modeled after the final selection examination room, surrounded by wisteria. Built surrounded by flowers.”

Mana said: "Then I will move all the ghosts in the examination room as soon as possible in the next few days. In addition, since the trainers are coming, if there are no special circumstances, let them bring a few ghosts to visit the Lord. Just give me a gift, it can be used for the final selection."

Ubuyashiki Yoshiya smiled helplessly: "In that case, why do we still need to build a No. [-] training ground?"

Mana said: "Because the hidden troops couldn't answer the question I asked before."

She explained to Uyashiki Yōya: "I asked them at the time, if the ghosts in the final selection examination room were not cleared after each exam, wouldn't they worry about raising ghosts that were powerful and far beyond the level that newcomers could handle? ?"

Ubuyashiki Yoshiya said: "Generally speaking, after the final selection, there will be no more humans in the venue, and ghosts will not be able to gain power."

Mana nodded: "The people in the hidden army also told me so, so I asked, can't ghosts increase their strength by eating ghosts?"

Ubuyashiki Yoshiya said: "I think the hidden troops will tell you that there are no records of ghosts gaining powerful strength by eating the same kind."

"That's right!" Zana said: "That's what he said at the time, but I told him that this answer is the best reason."

"Because you can only answer me 'There is currently no such record' instead of 'This is something that would never happen' and come up with reliable evidence to prove it."

Zhenna said: "It's about the lives of those children, so we should be more cautious."

How to talk about the strength level of the ghosts encountered in the final selection? Since the Demon Slayer Team has standards, of course they must abide by this standard.

It's just a pity that all the ghosts in the examination room were chopped down. They were just used for experiments this time.

"It would be a pity to casually chop up the ghosts you worked so hard to capture."

Ubuyashiki Yaoya shook his head helplessly: "In that case, there should be nothing else for the time being."

Mana immediately said: "Then I will go back first. Teacher Yaoya needs to have a good rest. You have been too tired recently."

Ever since he learned that the records about the users of the Breath of the Sun that were circulated in the Demon Slayer Corps were all the works of Heishimou, Ubuyashiki Yōya began to re-examine the legacy of the Demon Slayer Corps with his wife Amane Ubuyashiki and several children. historical records.

However, the Demon Slayer Corps has been around for thousands of years. Even though it has experienced several major crises during this period and a lot of data has been lost, the amount of data that has been preserved to this day is still huge. This is why Uyashiki Teriya is not with Uyashiki Yōya today. , he was still busy reviewing records.

If the people following the information this time were not Mana and Tomioka Giyu but someone else, the consequences would be unimaginable.

In addition, according to the intelligence of Tomioka Giyu and Mana, one of the Uejo who met this time was probably a member of the Demon Slayer Corps in the past, and there is a high possibility of knowing Enichi Tsukuni. The breath he used Dharma is currently unable to see any inheritance of the 'breath of the moon'.

It does not belong to the five common basic breathing schools.

What's more, the breath of the sun and the breath of the moon, just from the names, always make people feel that there is some subtle connection.

Thinking about it again, it was just a matter of following the fate of the country...

Well, Mana is always bound to have some strange associations.

But fortunately, the research on the reincarnation of the dirty land was finally discussed by Uyashiki Yōya.

Therefore, Mana is actually quite relaxed at this time.

Ubuyashiki Yoshiya said that the burden on her was heavy, but that was for ordinary people. Mana was a ninja, the kind who knew shadow clones.

Of course, even if it is a shadow clone, Mana will remove the clone regularly and then clone it again.

When the shadow part and the body disappear, not only the memory will return to the original body, but the accumulated fatigue will also return together.

The physique of a ninja is better than that of ordinary people, but it is impossible to withstand fatigue without limit. It is also for this reason that the art of multiple shadow clones and bodies has become a forbidden art.

Executing multiple shadow clones not only requires a huge chakra reserve, but also a relatively simple brain and action mode. Of course, the most important thing is that if too many shadow clones are divided at once, the body of ordinary people really cannot bear it.

But only one or two are acceptable to Mana.

In just a few days of research, even with the help of the shadow clone, it is impossible to make any breakthrough progress.

But Mana was sure of at least one thing.

Hei Death Mou's knife is really a part of his body to a certain extent.

Wouldn't this be great!

Remembering that when Black Death Mo broke the shadow clone, the shadow clone used the sealing technique to take the opportunity to leave a secret Flying Thunder God mark in Black Death Mo's body, Mana was immediately ready to make a move.

Of course, the more research materials the better.

Back then, Senju Hashirama's Wood Release Cells were only produced by Senju Tobirama by sending his eldest brother to the laboratory from time to time for a set of blood tests.

"It's been several days. With the ghost's recovery ability, Hei Shimo should have a new sword by now, right?"

It's time to steal again!

The God of Thunder flew over with a swish, then grabbed the knife and ran away!

Don't fight. It's a shame. After all, it is a rare renewable resource.
