Konoha Hidden Village, there is an underground space up to 100 meters deep, with winding pathways.
This is both Root's base and Konoha's new shelter.
However, the refuge function of Root has never been used, because when Danzo was in office, he would only allow Root Shinobi to take refuge, and it was impossible to allow civilians to take refuge.
When Chen becomes Fourth Mizukage, the villagers of Konoha no longer need to take refuge.
At this time, in the deepest laboratory of Root, Chen was lying on the operating table, and beside him were busy Orochimaru and Hiruko.
Now that the war is about to begin, there is no need for Hiruko to work as an undercover agent for Akatsuki Organization. After all, he will not be the boss after three years and three years.
And for such a precious scientific researcher, Uncle Snake needs him.
So Hiruko returned to the arms of Konoha and became a scientific research dog again, and he naturally participated in this operation.
The entire operation is actually very simple. All you need to do is transplant the cells from the spots into Chen's body, thus completing the acquisition of Indra's Chakra.
This does not have much technical content. After all, Ban's cells are different from First Hokage's cells. The latter has strong phagocytosis, but the former does not.
Although the whole process is simple, it is a necessary step to obtain Rinnegan.
It's not just that a random Uchiha Clan opens Mangekyo Sharingan and transplants First Hokage's Cells, and you get Rinnegan.
Because the power of Indra and Asura is indispensable!
In the original time and space, Obito not only had First Hokage's Cells, but also Mangekyo Sharingan. He was even on the verge of death when absorbing Ten-Tails... It can be said that Madara has experienced both Sasuke and Sasuke.
But Obito still does not open Rinnegan.
Because he lacks the power of Indra.
Kabuto said that Sharingan can eventually evolve into Rinnegan.
This sentence seems correct, but it is not accurate.
Because these two eye techniques are not the same type.
Rinnegan cannot be obtained through the further evolution of Sharingan. The highest evolutionary level of Sharingan is Eternal Mangekyō Sharingan.
The reason why Madara and Sasuke were able to activate Rinnegan is because they are the reincarnations of Indra, the eldest son of Sage of Six Paths, and possess the power of Indra themselves.
On this basis, transplant First Hokage's Cells (Asura), fuse the two powers of Asura and Indra to guide Six Paths Power, and you will have the opportunity to open Rinnegan.
Without these two forces, it would be impossible to get Rinnegan.
This is the so-called combination of Yin Yang Power on Stone Tablet, resulting in All Creation.
Now, Chen finally got the power of Indra and Asura at the same time.
But it doesn't mean that he can turn on Rinnegan immediately after transplantation.
Even for Lord Madara, after he combined the two powers, he went through a long process of fusion and only turned on Rinnegan when he was dying.
Sasuke also went through the dying process, and Sage of Six Paths came directly to give him strength, so that Rinnegan could be activated immediately.
Chen didn't think that he could obtain the ultimate power that took Madara most of his life to obtain in an instant.
If that's true, that's bullshit.
What Chen needs now is a near-death process, between the cycle of life and death, to promote the integration of the two forces and obtain Rinnegan.
Therefore, Chen placed this process of life and death on the mirror's pair of Mangekyo Sharingan.
Mirror's Mangekyo Sharingan, one is in the hands of Uchiha Yama, and the other is in the hands of Danzo, and now they have all been taken back by Chen.
Chen originally planned to transplant these eyes and get Eternal Mangekyo, but now there is no need.
The function of Eternal Mangekyo can only prevent the eyes from blindness, but the cells of Hashirama also have this effect.
Secondly, the so-called relationship with Sharingan is not evolutionary, but the fusion of the powers of Indra and Asura, leading to Six Paths Power and obtaining the new pupil technique "Rinnegan".
The original Mangekyo Sharingan directly covers the original eye technique "Sharingan".
Once Rinnegan is obtained, Susanoo's power will still be retained, but Mangekyo Sharingan's pupil technique may not be retained.
So it doesn't matter whether there is Eternal Mangekyō Sharingan or not.
But here comes the question, how to create the process of reincarnation?
Chen has already thought about this.
The two eyes of the mirror, the pupil technique of the left eye is called Naobi God!
During the battle with Uchiha Yama, Chen had been hit by this Genjutsu and spent ten years in it. He almost doubted whether his experience of Shinobi World was true.
In the end, if it weren't for System's forced interruption, Chen would probably have lived in Genjutsu until old age, and then died of old age in Genjutsu.
It can be said that the effect is extremely photogenic, and it is not an exaggeration to call it the strongest Genjutsu.
The right pupil of the mirror is named Omoikane, which has the opposite effect to Naobi God.
Omoikane will independently intercept a memory of the victim and reproduce it.
Once the magician falls into Genjutsu, he will have to experience a certain day in his memory, and it will be repeated!
The effects of the two pupil techniques are exactly opposite.
Chen wants to feel the passage of time, so he will choose Naobi God and Genjutsu.
If you want to win Genjutsu from Mangekyo Sharingan, someone needs to transplant Mangekyo Sharingan, and the one who accepts this task is Xin.
Xin was Danzo's test subject before, and even gave his right arm to Danzo.
Since Orochimaru took over Root, Xin has become a loyal believer of Uncle Snake.
And this person has an extremely special talent and will not have any objection to the task, so he is the best candidate to use Naobi God.
"Are you ready?"
Orochimaru and Hiruko were both wearing masks, and Xin was standing not far away, with a hint of excitement on his face.
"Okay, let's get started." Chen nodded.
"Naobi God."
The Three Tomoe in Xin's eyes quickly connected into lines and turned into a weird pattern.
Chen accepted this Genjutsu without any resistance.
Although the reality may only be a few seconds, he will spend a life that lasts for decades until he wakes up or is forcibly awakened by System.
This feeling is very similar to Captain America traveling through time and space, but a few seconds later, he appears in front of Falcon with gray hair.
For Falcon, it only lasted a few seconds, but Cap experienced a lifetime.
Chen won't age, but he will have to experience similar things.
He felt dazed for a while, a wave of chakra came from his brain, and then Chen fell into a coma.
