The Shikigami Fuujin officially appeared very rarely, and apart from the one that remains here with Tsunade, there may be no other inheritance at all.

Later, Orochimaru figured out the method to unlock the Shiki Fuujin only after accidentally obtaining the remaining information. Mizuki had never seen it, so he couldn't say for sure whether it was originally used this way.

"If that's the only reason, it won't convince me to give you the Demonic Sealing Technique. This technique is too dangerous. It's a forbidden technique that can cause people to be doomed to eternal damnation. It shouldn't be passed on to outsiders."

Mizuki already knew that it would not be easy to convince Tsunade, but he did not expect to be rejected so simply.

Every ninja knows that forbidden techniques hurt others and oneself, but when facing a life-and-death battle, they will always use this power unconsciously.

Once it spreads, it will be difficult to ban it.

Shuimu sorted out his words and said patiently:

"I have never seen this technique in person, so I cannot accurately judge its value. I only have some unconfirmed conjectures. It would be a bit troublesome to explain it in detail..."

"I have time, you can talk slowly..."

Tsunade poured herself a cup of hot tea and leaned back in her chair, waiting for Mizuki to explain in detail.

"The story begins more than ten years ago when the Fourth Hokage Minato sealed the Nine-Tails."

Mizuki had a reason that he had prepared long ago.

"The Nine-Tails in Naruto's body is not complete. The Fourth Hokage used the Demonic Fuinjin to split the Nine-Tails into two halves, and one half was sealed along with the Fourth Hokage."

"Only half of the Kyuubi?"

Tsunade thought about it carefully and then said.

"This is possible. Since the Nine-Tails is sealed, it is not inconceivable that the one in Naruto's body is only a part of the Nine-Tails. So, you mean to release the other half of the Nine-Tails?"

Whether it is to create another Nine-Tails Jinchuriki or to strengthen Naruto's combat power, it is a good choice.

Now there is a real member of the Uzumaki clan in the village, and Karin is also a good candidate for the Jinchūriki.

"As far as I know, there is no way to remove the Demonic Sealing Technique, right?"

"As long as it's a seal, there must be a way to unlock it!"

Others might be bragging when they say this, but it is hard to refute what Shuimu said. There are not many people who can brag with Shuimu about their attainments in the art of sealing.

"So you are capable of solving it?"

Mizuki shook his head.

"I've never seen it before, and I don't know what's going on yet. Just give me some time, and it shouldn't be a problem to figure it out."

"If that's the case, I reluctantly agree, but before you can unlock the Demonic Seal, you must get my consent!"

When it comes to the Nine-Tails, Tsunade has to be cautious. If Mizuki creates another Nine-Tails Jinchuriki for no reason, who knows how big a turmoil it will cause.

Not only that, the Shiki Fuujin contains the souls of the four Hokage and Orochimaru's hands. If Orochimaru recovers his strength, it will be a great threat to the village. So Mizuki must be urged to act cautiously.

"Now that we have reached an agreement, let's move on to the next question. What are you going to use in exchange? This kind of S-level sealing technique cannot be obtained with simple things!"

"S-class Wind Style Ninjutsu: Rasenshuriken!"

Anyway, it will be a long time before Naruto creates this technique, so there's nothing wrong with exchanging it!

Mizuki stretched out his right hand, chakra condensed in the palm of his hand, and a buzzing rotating blade wheel appeared in the small office. The phantom of the sharp edge of the blade made people feel palpitating, and the sharp aura contained in it hit them in the face.

"Okay, stop now. Be careful not to blow up the building."

Tsunade pressed her forehead and said helplessly.

"It's very powerful, worthy of the name of S-level ninjutsu. However, you just plagiarized the ninjutsu of the Fourth Hokage and changed it casually in exchange for the legacy left by the Fourth Hokage. Isn't this too much?"

"Casually? Too much?"

He spoke in such a arrogant tone. After all these years, no one has come up with such tricks or plagiarism. Mizuki admitted it. It would be an exaggeration to say that it was casual. It was obvious that he wanted to suppress the value of the Rasenshuriken.

Shuimu had no choice but to ask for help from others, so a heavy loss was foreseeable.

He reached into his ninja tool bag and took out a small wooden box, opened it and handed it to Tsunade.

"What's this?"

The short black stick, which seemed to be made of metal, looked inconspicuous.

Tsunade picked it up curiously, then her face changed drastically and she immediately let go of it, letting it fall on the table with a clanging sound.

"It can actually disrupt the chakra in the body?"

It was just a brief moment, a slight touch, and my body almost lost control. This was something I had never experienced before.

“Isn’t it amazing?”

Mizuki smiled, took out the tweezers he had prepared long ago, picked up the gangster, and put him safely into the wooden box.

"This thing is the product of Yin Yang Escape."

"Yin Yang Escape, is there really such a magical thing in the world?"

There are a few myths and legends in the ninja world that mention this word, and the origin of this word can be traced back to the Sage of Six Paths, but most of them cannot be believed.

"The Samsara Eye has appeared, so Yin Yang Escape is not surprising."

Not only the Six Paths Sage, the Rinnegan and the Yin-Yang Release, but also the Ten-Tails have appeared in the tales passed down from ancient times.

Most ordinary ninjas don’t even know about Jinchūriki. Those who know about the nine tailed beasts are the high-ranking officials of the five major ninja villages.

The legend of the Ten Tails was only mentioned in a few words by the descendants of the direct descendants of the Six Paths Sage. Mizuki had seen similar records in the library of the Hyuga family. The Senju and Uchiha, who were also descendants of the Six Paths, naturally knew about it. However, most people regarded it as a joke until the Rinnegan appeared in the world.

Tsunade looked at the small metal rod in front of her with complicated eyes.

"What's the use of it?"

"I don't know. I just found that it has a strong chakra-restricting effect. At the same time, it is also an excellent chakra-conducting material."

"Conducting chakra? Where did you get that?"

"I fought with those clones who possessed the power of the Rinnegan, and got it from them accidentally!"

"I know that. You never told me that you got this good thing before..."

"You didn't ask!"

Anyway, it is a private action outside the mission, so there is naturally no requirement to hand in the spoils. Just like when you go out for a walk in your spare time and pick up a large sum of money, you naturally cannot force it to be returned to the public. As long as no one claims it, it is yours.

…

After much trouble, Mizuki finally got the Shiki Fuujin and breathed a sigh of relief. The last piece of the puzzle in the plan was completed. As long as he could get the Death Mask kept in the Nanmen-do, the ancestral home of the Uzumaki family, the last variable would be under control. The Fourth Ninja War still needed the contribution of four former Hokage.
