The research on ninjutsu is rigorous. After unremitting efforts and a lot of experiments, Mito finally confirmed that no existing sealing technique could be used to make such a scroll.

A powerful and brand new sealing technique is required, and the materials need to be found separately. At least the skin of metasequoia cannot be used.

Afterwards, Mito plunged into the vast sea of ​​books, and the development of the new seal technique was not easy. At least the level of this seal technique was far higher than that of the S-level seal, otherwise it would be impossible to seal something magical like time.

Xuan naturally went to help. Although he was not very good at sealing techniques, as the three gods of the Warring States Period, his attainments in ninjutsu were undoubtedly master-level. The ninjutsu exchanged from the system also needed to be developed and used. Xuan had worked hard in this area since he was a child.

When Uchiha left, a lot of the books were taken away by Gen. In addition, the various materials about sealing techniques collected by Mito and the "Akira" organization itself were developed, which was a vast sea of ​​books.

Most of the information is naturally useless, and it is like this that it can be developed, boring and boring.

It took about three months before the two men read all the information. Xuan even took her to the moon, allowing her to feel the power of the reincarnation eye up close.

After returning, Uzumaki Mito chose to go into seclusion, and even Ken was driven out and locked himself in the house alone.

It was another two long months.

When she saw Mito again, she was extremely haggard, but a smile appeared on her face.

Xuan hurriedly stepped forward and supported her, and said with concern: "Are you okay?"

Mito fell softly in his arms, shook his head weakly, "It's okay, it's just overdrawn."

"This is for you."

Gong took it and it was a ninjutsu scroll. It did not open it now, but helped Mito go to the residence to rest.

"This is a new sealing technique I developed. Sorry, I can't complete it all. I have checked various ninjutsu scrolls and classics, and can only propose a rough set of theories and effects. I don't know whether it can be done." Mizuto said tiredly when she was supported by Ken. Her eyes kept drooping as she walked, looking like she was about to fall asleep.

"It's already good. Go and have a sleep to keep your energy healthy. When you wake up, I've got everything done."

Without replying, Ken lowered his head, and Mito was already asleep in his arms.

He carried her into the room and put her in the bedding, and then ordered the little maid to take care of her. Xuan turned around and left.

...

Somewhere in my backyard, I opened the scroll that Mito gave me, with dense words written on it, and nothing else.

After reading it by Xuan himself, the above is a completely inference of a brand new sealing technique, which is derived from the theories of several existing strongest sealing techniques, such as the Four Symbol Seal, the Eight Trigrams Seal, etc.

Even if it is deduction, it is not a complete random guess, but a complex and cumbersome process. Even Mito recorded these words clearly.

After reading it carefully, Xuan put away the scroll silently. The theory inside is not complicated, and it is basically something that can be traced.

The reason why the power of time and space is difficult to be sealed by the sealing technique is that all the current sealing techniques are changes formed by ordinary chakra. At the initial level, the possibility of sealing the power of space and space is lacking.

If she wants to complete a new seal, she must make a fuss about the source of Chakra, so Mito conceived a brand new seal, which she herself called the "Yin Yang Time and Space Seal".

The reason is very simple. In the sealing technique, he used the most creative chakra, the most creator-attributed chakra, and then developed a new sealing technique based on the "Li Si Si Seal" and "Psychological Seal", which was the "Yin and Yang Time and Space Seal" he conceived.

However, there are several unsolvable problems in this set. The first point is that the consumption of chakra. The chakra required for this set of seals will be huge according to Mito. I am afraid that no one can afford it except the tailed beast.

Qian was not very worried about this. Not to mention that he had a system that could restore chakra infinitely, even if he had to exceed his upper limit, he still had the perverted and heretic golem. At a big deal, he could still capture a tailed beast, and there was a giant reincarnation eye in the moon. Anyway, there were many ways.

The second point is the material problem. Sealing techniques at this level have reached the level of six-level seals, and the carrier has deviated from the scope of general materials. According to Mito's inference, the skin of Metasequoia is incompetent. There must be a material with strong vitality, and it also needs to be that kind of soft vitality.

On this point, Xuan frowned. He could find a way to solve other things, but the material problem could not be solved by ninjutsu.

After thinking for a while, Xuan stood up and left, and there was only one step left before success. If he was stumped by the material problem, wouldn’t it be a joke?

Afterwards, he activated the ability of the "Xiao" organization and asked to collect the skin of Metasequoia for more than a hundred years.

The entire "Xiao" was dispatched under the command of the leader. In fact, after years of development, "Xiao" has expanded to an extremely exaggerated situation. It is no exaggeration to call it a giant. Even in its own inventory, there are many metasequoia skins and other objects, but only two of them have been in more than a hundred years.

After all, this kind of thing is hard to find. With the power of "Xiao", only one piece of inventory that has been more than a hundred years old was found, and it was collected by a large family in the Tea Country.

Later, Hinata Tamamo took action. It was said that he had secretly gone to the Hinata clan in Konoha Village and got two hundred-year-old metasequoia barks there.

On the third day after the order was issued, Xuan sat at home and five hundred-year-old bark were sent to Xuan's hands.

After that, Xuan put away, thought about it and asked them to send the "Shui Yuanzhu" from the base, and then went to the moon alone.

When he came to the inside of the moon, he went directly to the reincarnation eye.
