The Rinnegan is a good thing, but it is difficult to find a ninja who can be trusted and has the ability to withstand the consumption of the Rinnegan.

With Uchiha Obito's qualifications, his right eye is the Mangekyō Sharingan, his left eye is the Rinnegan, and almost half of his body is White Zetsu cells, which can provide extremely huge vitality. Under such conditions, he can barely use the power of the Outer Path Statue, and his control is not very effective, and he almost let the Ten Tails get out of control.

For an ordinary ninja, if they transplant the Rinnegan, it would be good enough if they could avoid being killed by the backlash. It is even more unrealistic to be able to use the power of the Rinnegan freely.

Not to mention the Rinnegan, it is not easy to transplant a Sharingan which consumes much less energy.

Otherwise, Kakashi Hatake's chakra amount wouldn't be so limited, and after Danzo Shimura seized Uchiha Shisui's Mangekyō Sharingan, he wouldn't have had such a hard time using it. Later, he took great pains, transplanted the first generation's cells, and asked Orochimaru for help, before he could barely use it.

It is truly amazing that Nagato, with his mortal body, can use the Rinnegan to such an extent.

He is neither a member of the Uchiha clan nor has he transplanted the cells of the First Hokage, Hashirama Senju and White Zetsu. But before summoning the Gaiden Demon Statue, he was able to use them freely and without any abnormalities. It is really amazing.

Looking at the current group of ninjas in Konoha, no one has such qualifications.

Even Uzumaki Naruto doesn't have this ability because he has to be distracted to suppress the Nine-Tails.

Karin, who is also a descendant of the Uzumaki family, is too young, and her talent and specialties are not super physical strength and huge chakra, but sealing techniques and perception. Although she is much stronger than other ninjas, she is still far behind Nagato.

In this case, if one wants to use the power of the Rinnegan, the only way is to rely on the methods of researchers like Mizuki and Orochimaru, and use biotechnology to allow talented ninjas to adapt to and be able to withstand the Rinnegan, thereby unleashing powerful combat capabilities.

It would be fine if it is not used, but if the power of the Rinnegan is to be used, a suitable successor must be found.

Jiraiya couldn't fully understand the advice of the Great Toad Sage, but he still agreed with this method of handling it, but...

"Why not use the power of the Rinnegan immediately?"

The Great Toad Immortal explained:

"The Rinnegan has not appeared since the Six Paths Sage, and there is a reason for that. Those who can possess and control the power of the Rinnegan are very powerful, but that is not necessarily a good thing. A power that is too powerful will be envied by the whole world. As long as this thing is not destroyed, it will always bring misfortune."

Even the eternal Mangekyō Sharingan cannot destroy the world to the same extent as the Rinnegan. The power to control the Ten-Tails is simply too terrifying.

"Please be patient for now, little Zilai..."

The Great Toad Sage looked at Jiraiya who was a little confused and shook his head.

"These things are important, but they are not as important as the child of destiny. Only he can decide the future of the ninja world. Watch Naruto carefully. He will solve these problems and bring a better future to this world."

"Understood!"

Although I didn't get the answer I wanted, I was able to sort out the priorities of the matter.

The most important thing is to improve Naruto's strength, guide the child of destiny and prevent him from going astray. It would be a pity if a tragedy like Nagato happened again due to negligence.

…

Things haven't been going smoothly for the Hidden Mist Village recently. They didn't get the Three-Tails that they had expected to retrieve, and they suffered heavy losses and returned empty-handed.

Although there were no serious injuries, it was still a setback.

The losses of the Hidden Mist Village were smaller than those of the Hidden Leaf Village, but the two's ability to withstand blows were completely different.

For the Hidden Mist Village, which is in urgent need of restoring its strength, every Mist Ninja is a valuable asset, not to mention that this time the losses are not just one or two.

The blame for this incident cannot be placed on Konoha Village. To say that the ally who was highly expected did not try his best would be a lie.

Even after mobilizing a large army and including Jiraiya, one of the Three Great Ninjas, who took action, they still did not get a satisfactory result. It can only be said that the enemy was still too strong.

Such a result made the Fifth Mizukage Mei Terumi quite disappointed.

When Yan Liu and the Mist Ninjas returned from the Land of Fire, they were no longer as depressed as they had been. After treatment and a short period of recuperation in Konoha Village, the survivors were basically no longer in danger of death, and most of them had recovered their health.

The medical system of Konoha Village taught the Mist Ninjas, who only knew how to kill, a good lesson about the strength and foundation of a great ninja village.

Because the operation to capture the tailed beasts was not smooth, the Sand Village and the Mist Village, led by Konoha Village, had to strengthen their cooperation again to resist the threat that might come at any time.

At the same time, Mifune, the leader of the Land of Iron, who had previously contacted the major ninja villages to sign an alliance but failed, sent envoys again, hoping to facilitate a Five Kage Conference to formally discuss how to deal with the "Akatsuki" organization that threatens the entire ninja world.

The undercurrents in the ninja world attracted the attention of many interested people.

But all this has nothing to do with Uzumaki Naruto for the time being.

Improving our strength is the top priority.

Under the watchful eyes of a large number of people, with the assistance of Kakashi Hatake, Tenzo and Karin, who provided a lot of help, and Sakura who came to help from time to time, Uzumaki Naruto finally mastered the Wind Style: Rasenshuriken.

After mastering this powerful ninjutsu which took him a lot of effort to practice, Uzumaki Naruto's joy was beyond words.

Although it cannot be used freely, and it still needs the help of two clones, one to control the shape changes of the spiral shuriken, and the other to inject wind-attribute chakra to change its properties, but it is at least a successful start.

However, after trying it a few times excitedly, Uzumaki Naruto couldn't help but become greatly frustrated.

"Why can't I throw the Rasenshuriken like Mizuki-sensei?"

As long as it left his palm for a while, it would explode violently, and he almost hurt himself a few times.

Not only that, every time he uses it, he puts a lot of pressure on his arms. It is hard to imagine that if this technique is a close-range ninjutsu, it is hard to say whether Naruto can successfully hit the enemy with his own physical skills. At this level, it is not much stronger than the Big Ball Rasengan.

It is enough to know only one ninjutsu with the same attack method and similar power.

In response to Uzumaki Naruto's complaint, Hatake Kakashi replied:

"Practice it first. If you want to use it better, you need to study hard. The next training will be even harder than it is now. Are you ready?"
