Naruto: The Strongest Sage.

Kumogakure, the Raikage's office. At this time, the office had been smashed to pieces by the Raikage.

In fact, ever since Aoba cut off his arm, the Raikage has been in a bad mood. The last time they went to war with Konoha, the elite troops of the Kumogakure vanguard were all killed, which made the Raikage so angry that he vomited blood.

Although he also understood the latter two, Kumogakure and Iwagakure were used as pawns. But it was an indisputable fact that thousands of soldiers died at the hands of Konoha.

The most important thing is that his brother Killer Bee was also missing in that battle. The Raikage has been almost depressed since then.

Not long ago, Akatsuki attacked Kumogakure. Although they retreated quickly, Kumogakure was unable to retain any of the other side.

One of the five great ninja villages in the ninja world was being taken over by a bunch of scoundrels who came and went as they pleased. Every time the Raikage thought of this, he felt like vomiting blood.

This time, the Raikage was furious again because he received news that the Akatsuki guys were going to come to Kumogakure again.

"Gather the best 100 elite soldiers in the village, with the wooden man as the core, and set a trap. This time, no matter how many people come, I want them to stay here forever."

In fact, Kumogakure had already guessed that the Eight-Tails had fallen into the hands of the Akatsuki organization. But the Raikage still held out a glimmer of hope, hoping that Killer Bee had only been captured and was not dead.

His idea was that if he could capture someone from Akatsuki, he might be able to get his brother back.

While Kumogakure was preparing for war, the Akatsuki organization in Rain Country was also holding a pre-war meeting. However, only Nagato, Konan, and Hiruko Kakuzu attended the meeting.

Of course, when Hokuro was present, Nagato appeared in the form of Tendou.

The internal structure of Akatsuki is very interesting, because both Konan and Nagato know clearly that the members of Akatsuki are of complex composition and cannot all be trusted.

At present, the only people that Konan is truly sure to trust are Kakuzu and Hiruko. These two guys have no way out and are truly committed to the cause of the Akatsuki organization.

Among them, Kakuzu is responsible for the finances of Akatsuki, and Hiruzen is responsible for various research and development work.

Unlike other people in Akatsuki, Hiruko did not have so many small thoughts in Akatsuki. His purpose was very simple. At present, the Land of Rain was the only country that accepted him and supported his research.

In addition, Nagato is the master of the Samsara Eye. His strength is the best in the ninja world. Whether it is resources or safety, the Rain Village is full. Therefore, Hiruko has a strong sense of identity with this place.

He might be the person who least wants the Rain Country to have problems, except for Nagato Konan. After years of wandering, he even thinks of this place as his home.

After a period of observation, Xiaonan also found that Beiluo could be trusted to a certain extent, so he gave him Nagato's cells, hoping that his exploration could help Nagato.

Unfortunately, Nagato's problem was not physical, but the exhaustion of his vitality. This was not something that could be solved by technical means. At least that's what Hiruko thought at first.

Until Xiaonan received the life potion sent by Qingye. This thing is made of extremely pure life force. It can directly replenish the energy consumed by Nagato.

After Beiluhu studied and analyzed this thing for the first time, he felt that all his three views were overturned.

"This is a very pure potion that concentrates life force. I don't know how this was done. On the surface, it seems that a sealing technique was used to bind the life force.

But the key question is, how can we separate the vitality? It is simply impossible, right? "

"You can study these questions later. What I want to know now is, is this medicine harmful?"

"Of course not. Strictly speaking, this is not a potion at all. It is a concentrated ball of life force. No matter who it is given to, it will only benefit them and not harm them."

"Very good. I'll leave the sample for you. Try to see if you can replicate it."

After confirming the effect of the potion, Xiaonan also understood the intention of Qingye's letter.

At the same time, in the Kirigakure laboratory, Black Zetsu swallowed another White Zetsu and finally managed to stabilize his body.

"Lord Madara, according to our intelligence, the defense of the Rain Country will be loosened in three days. Their elite masters will go to Kumogakure to capture the Two-Tails."

"Very well, then let's take this opportunity to get back the Rinnegan. I've had enough of this body without feeling."

"But Madara-sama, it is the Rinnegan after all, should we make more preparations? I can awaken an army of White Zetsu."

"That's not necessary. He is not the master of the Rinnegan and cannot bear the consumption of the Rinnegan. Not to mention exerting the true power of the Rinnegan. Just act according to the plan."
