Naruto's opening eternal eye

Scorpion has already determined the production method of the regenerative nucleus, but it has not been practiced yet.

The production method of the regenerative core is similar to that of the human puppet's chakra core.

It is necessary to separate the places with the highest chakra density in the ninja's body as much as possible before the ninja is alive, and then use special methods to preserve them.

Then perform a sealing technique to turn these chakra-active bodies into chakra cores that can use chakra and ninjutsu in life.

This can preserve the puppet's original strength to the maximum extent.

The more completely the part of the body with high-density chakra is preserved, the closer the strength of the human puppet will be to the one in life.

But the part of the body that is made into the chakra core will lose its activity, so the puppet cannot make chakra by itself, but needs the user to transmit energy to it through the chakra line.

On this basis, the regeneration core retains the activity of that part of the body.

Then, by constantly replenishing some special chemical solutions, the chakra can be continuously regenerated like a living person, which is also the origin of the name of the regenerating nucleus.

The last step is to use a sealing technique taught secretly by Sand that can seal consciousness, and inject consciousness into the regeneration core.

At this time, the regeneration core is completely perfect. It can replace the body as the core carrying soul and chakra, and can also control the puppet's body through puppetry.

After getting the method to make the regeneration core, Mo Nan's first reaction was that he had got something useless.

It is made in a place where the regenerative core requires the use of a large amount of chakra accumulation in the body. The more chakra is accumulated, the more important that part is to the body.

Maybe they won't die immediately after separating those bodies, but the damage to the whole body is also great.

Coupled with the loss of a large amount of chakra, even if you can find a way to barely survive, the whole person is basically useless.

Although the regeneration core is quite interesting, it is impossible for Mo Nan to make such a big sacrifice just to try a ninjutsu.

Moreover, in order to complete the most important step of the regeneration core, he would completely abandon his original body and inject his consciousness into the regeneration core. This is also a stupid thing that Mo Nan would never do.

Mo Nan, who studied many sciences in his previous life, including physics, chemistry, and biology, has a deep understanding of how mysterious and powerful the human body is.

Obviously, he doesn't have much understanding and development of himself, but for the so-called pursuit of art, Xie actually looks far away.

It would be foolish to give up the truly great works of art that nature makes.

But just when Mo Nan thought that the regenerative core was useless and was about to forget about it.

However, Mo Nan thought of the tree clone that he had left in the Forest of Death and had no other use except being able to sense the surrounding situation.

"What is needed to make a regenerative core is mainly the chakra lodged in the body, not the body itself.

Maybe not a human body, but something else with chakra accumulation would it be okay too.

If I extract a part of the tree clone to make a regeneration nucleus, as long as the activity of that part can be preserved.

And relying on the connection with the avatar Chakra, even the step of injecting consciousness can be omitted, and it can be completed directly. "

Thinking of this possibility, Mo Nan was stunned, as if he was calculating something in his mind.

At this time, the ANBU ninja also arrived at the Hokage building and was talking to the third generation.

"Reporting to the third generation, we just found signs of someone fighting in the woods to the north.

According to the traces left at the scene, one of them should be the puppet master of Sand Yin, while the identity of the other party is temporarily unknown. "

The third generation heard the reports from his subordinates and thought to himself that the battle with Sunagakure Village was over and he was already preparing to sign an alliance agreement.

At this time, there is a ninja who is hidden in the sand fighting with people outside Konoha Village. What does it mean?

Either Sunagakure had other ideas, or someone was deliberately setting the blame, intending to reignite the conflict between the two villages.

This matter must be handled with caution, if you are not careful, the war that has just subsided may be rekindled.

Thinking of this, the third generation sighed and said:

"In that case, I'm going to see for myself. I want to know who has the guts to run wild in Konoha."

The third generation and this Anbu arrived at the place where the huge movement had just happened, and the third generation was shocked as soon as he arrived at the scene.

A large number of fallen trees and severely deformed ground are definitely not something ordinary ninjas can do.

If there are only two people fighting, then the strength of these two people is simply incredible.

After seeing the third generation coming, the former dark army leader hurried over to report to the third generation.

"Akagi, you guys have been here for a while, right? Did you find anything else?"

The third generation asked Akagi, the ANBU captain who rushed over.

"Yes, Sandaime. After careful investigation, we found that there were only two people on both sides of the war.

But there was a third person here, but I don't know why he didn't join the battle. "

"The strength gap between the two warring parties should be huge, because we found some bloodstains at the scene.

But the blood was only from one of them, and no trace of injury was found on the other. "

"And there were no bodies at the scene. I don't know if they were taken away after being defeated by another person, or if they managed to escape on their own."

"Furthermore, the three people at the scene seemed to be very cautious, and they were very clever in covering their tracks.

In addition to being able to vaguely judge from some footprints, one of them probably came from the direction of Konoha Village.

The other two showed no sign of appearing or leaving at all. "

After hearing Akagi's report, Sandai also had some speculations of his own.

The scene was filled with the remains of a large number of puppet masters, but there were no traces of the ninjutsu used by another person.

Being able to cause such havoc is not something a puppeteer can do.

It is very possible that these destructions were done by another person who was fighting with this puppet master.

"Have you carefully examined the traces left by the other ninja? Do you know what kind of ninjutsu caused them?" Sandai asked again.

There was no emotion on Akagi's masked face and he just apologized:

"Sorry Sandaime, the other ninja left too few traces, and we really can't figure out what kind of ninjutsu was used to cause it.

It was only discovered that there were some strange footprints left at the scene, like the bones of some huge creature.

It may be some kind of psychic beast left behind, but we really can’t tell what kind of psychic beast’s footprints it is. "

"The footprints left by some kind of huge biological skeleton, it can't be!"

The third generation felt a little heartbroken when he heard this, and hurriedly asked.

"Where is that footprint? Hurry up and take me to see it"

So Akagi led the three generations to the place where Mo Nan summoned Susan, and saw several rows of huge footprints on the scene.

It was left behind when Mo Nan controlled Susanoo to jump in order to avoid the poison gas attack of the scorpion.

There is also a large circular pit with spiral marks next to it, which was caused by Mo Nan when he used the spiral shield.

Sandai didn't know what this strange pit was about, but the rows of huge footprints were very familiar to him.

Because he had just seen it on the Wind Country battlefield before.

The third generation thinks that he will never be wrong, Susan's footprints are quite special.

There are very few large psychic beasts, and the shape of this footprint is quite close to the shape of human footprints. It is definitely Susanoo's footprint.

That is to say, the other party involved in the battle is Uchiha Hua!

Why did he clash with the ninja of Sand Hidden around Konoha again? What is his purpose of wandering around Konoha?

What is the purpose of that puppet master around Konoha? And who is the third person watching the game?

Many questions suddenly popped up in Sandai's mind, but he didn't know where to get the answers.

"It just so happens that the people sent by Sha Yin to negotiate are about to arrive. I might take this opportunity to learn something from them and hear their explanations."
