The scale of Konoha Research Institute is now getting bigger and bigger.
Chakra Cloak has been developed to the fifth generation. Although it is still unable to be popularized by all people, the adaptation rate of civilian ninjas has increased several times. The gap with bloodline ninjas is rapidly narrowing.
According to this speed, within two generations, it should be completely equal. After that, the assembly work of Chakra Cloak can be fully promoted.
At present, the development work of Chakra Cloak is fully taken over by Sakura. As the research assistant of First-Generation Chakra Cloak, plus a personal user.
Among Konoha, except Aoba, no one is more familiar with this field than Sakura.
Tobirama Senju is responsible for more in-depth research.
Previous research on the body tissue of Black Zetsu has been temporarily sealed because there is really no progress.
The research on Aoba Mangekyō fusion has also been suspended. Because it is obvious that Six Paths secretly did something to prevent him from succeeding.
Therefore, Aoba gave Tobirama a brand new research topic, Pure Land.
As the developer of Impure World Reincarnation, Tobirama thought that no one knew this ninjutsu better than him. But what he didn't expect was that what Aoba wanted to study was not the jutsu itself, but the dead world.
"Any progress?"
In the laboratory, Aoba asked Tobirama.
"A little bit, but not enough." I asked at least twenty ninjas who came out of Impure World Reincarnation, and their descriptions of Pure Land were all... different.
Tobirama looked troubled. It seemed that this result also made him somewhat incomprehensible.
Although he died, he did not go to Pure Land. Instead, he was sealed in the belly of Reaper. Therefore, he has never seen the real Pure Land.
The descriptions of those reincarnated ninjas are Wuhua Eight Gates.
Some said that Pure Land was a void. They wandered around in it in a daze until they were summoned by ninjutsu and regained consciousness.
Some said that Pure Land was a darkness, and they were struggling hard in it. They didn't see a glimmer of light until they were summoned.
Others said that they had no memory at all. They lost any consciousness after death and did not remember that they were dead until they were summoned.
Such statements, Wuhua Eight Gates. I have listened to dozens of versions, but I still haven't gotten a definite answer.
However, Aoba never meant to give up. Instead, he let Tobirama continue to experiment, then record all the information, and compare them one by one from the massive information. Try to find the required information.
It's just that Tobirama Senju still doesn't know what Aoba wants to know.
"I actually don't know. Simply put, what I'm looking for is some kind of disharmony."
"Disharmonious?"
"That's right, something is obviously wrong with Pure Land in Shinobi World. Birth, old age, illness and death are human nature. And after death, life either completely dissipates or enters Reincarnation. Why is it stuck in Pure Land?"
"Why not?"
Unexpectedly, Tobirama Senju did not agree with him as expected. Instead, he had some strange questions from Aoba.
Aoba was stunned for a moment. He didn't expect that Tobirama Senju didn't notice this problem. But after thinking about it, he understood it again.
My concept of death comes from the past life, or the theory of the past life. After all, there is no final conclusion about the world after death and the past life.
But there are only a few possibilities: disappearing, or Reincarnation. But no matter what, it is impossible to stay in a certain world.
Even if it is hell, it is only punishment. After the punishment is over, you will still have to Reincarnation.
But in Shinobi World, there is no such concept. Going to Pure Land after death is a matter of course.
The lack of information leads to the different concepts of Tobirama Senju and Aoba.
Aoba thought for a moment and changed the angle.
"Let's put it this way. If all the people who died were in Pure Land, then shouldn't there be more and more people in Pure Land over the past thousand years?
According to this concept, how big does Pure Land need to be? Because as long as Shinobi World is immortal and civilization continues, more and more people will go to Pure Land. The simplest question is, how big is Pure Land to accommodate so many people? One day in the future, what will happen if it is not big enough?"
"..." After Aoba finished speaking, Tobirama Senju looked at him with a strange look.
"Why are your thoughts so strange? Is this kind of question something humans should think about?"
"Originally I didn't use it. But now I have to consider it."
"... To deal with him?"
"Yes, and there is no need to be too evasive. In fact, I don't think he can master everything about Shinobi World. To be more direct, he should only be able to master the information about Shinobi World through the reincarnations of Ashura and Indra."
"... I'm sorry, I can't be as calm as you when it comes to him. Also, are you sure my eldest brother can't come back?"
"About 99% sure."
"... Get out of my laboratory, I want to continue working."
Aoba was kicked out, but he was not angry. He could understand the feelings of Tobirama and Tsunade.
After all, that is Hashirama Senju. The god of Shinobi World, the existence of one person who subdued Shinobi World. He disappeared so silently, and may even have lost himself. It is good that the two of them did not have a cognitive breakdown.
Back at the training ground, Hinata and Neji have woken up and are now exchanging experiences.
"How is it? Did you gain anything?"
"With some teachers, I have begun to sense subtle changes at the muscle level. I have also noticed some hidden injuries left by previous training. With this kind of perception ability, we can perfectly control the training volume and master our own body information during training.
Always use the method that suits you best to train and improve yourself."
"The summary is very good, but it is still only superficial. You still need to have a deeper understanding of your own body, from muscles, to bones, to internal organs, to every small organ, and even to the cellular level."
The two of them didn't understand why they had to do it to this extent, but when the teacher spoke, they naturally had to work hard in that direction.
Aoba also has no explanation for the time being. The intention is actually a bit complicated.
The most basic demand is that Aoba wants to know the secret of Byakugan. Hyuga does not know, but Aoba does. Byakugan can be fused. But the technology is in the hands of the descendants of Hamura Otsutsuki on the moon.
What Aoba wants to do is to deeply study the composition of Byakugan and find out this method. It also hopes to bring some inspiration to the integration of Sharingan.
The deeper reason is that Neji and Hinata were booked by him, and they may become important combat forces on his side in the future.
I have drawn the future Hinata more than a dozen times, and I can barely get a hint of it...
