The temporary leader, Kouji, who was immersed in his research, raised his head.

"That's true. I'm sure you already know the general result. But there are still big problems in practical application, because when it comes to these metaphysical studies, in addition to philosophical exploration, more importantly, there is a lack of experimental proof at the quantum theory level..."

"Let's not talk about this for now. So-called science, including quantum theory, was originally just a branch of philosophy. It was only later that it was divided into natural science and humanities and social sciences. We don't need to understand it now, as long as we can use it."

"I understand that this kind of purely theoretical stuff really can't be understood by just using chakra tricks."

"Let's be practical. To make a long story short, I'll just slowly look through your memory of what happened."

Gongzhi nodded, sorted out his thoughts, and explained:

"Yin Yang Release, a magical art that creates miracles of life, is one of the most basic rules of the Ninja World. First, we must understand what life is..."

"Are you trying to argue with me? We've discussed this before. We can't define what life is. The most we can do is to confirm what life is. Animals, plants, summoned beasts, microorganisms, fungi, viruses, etc. are all life. By the way, because of chakra in the ninja world, there are many non-carbon-based life forms. I won't list them all..."

Gongzhi waved his hand.

"I know all this. We can only add bricks and tiles to the concept of 'life' and improve it bit by bit, but we may never get an accurate answer. For example..."

Gongzhi kicked the rock stool next to him.

"We can't even tell whether this thing is considered life!"

Stones are definitely not organic matter. If they were in the previous life, they would not even be considered life. However, in the ninja world, because of chakra, the definition of life has been greatly broadened.

The ninja world is pan-conscious, and uses chakra as a medium and the beliefs in tailed beasts and various gods as carriers to subtly support this world.

This stool without any signs of life is also a part of the ninja world. If you insist on saying that it is a life, it is not too far-fetched.

Just like a person is a life, each cell that makes up him will definitely die if taken separately, but when they form a whole human being, they are indeed full of vitality.

Perhaps, the stool under your feet is a cell or tissue of the "big life" of the ninja world, contributing its own strength to the vitality of the ninja world - natural energy.

The lack of life characteristics may be due to the fact that humans cannot observe them. Just like in previous science, humans cannot observe dark matter and dark energy, but can prove their existence through indirect methods.

But Shuimu doesn’t have the time to study these basic things now. Without the full support of the world, he won’t be able to come up with anything in one or two hundred years.

"That's right. We can determine from experience that something is life, but we cannot confirm that it is not life, because..."

"Because of Chakra!"

"That's right!"

Gongzhi nodded.

"Like Immortal Technique: Inorganic Reincarnation Technique and Thousand Commands, both use natural energy to give life to lifeless inorganic matter or even chakra derivatives, but is this really giving life? Maybe we just happen to activate their invisible vitality. Otherwise, do you think you can create life with such a lame method? Not even temporarily! It's not that I look down on humans, but to create life out of thin air, you still need a creator like God."

"That does make some sense."

Shuimu lowered his head and thought for a while.

"It seems that getting the reincarnation of Chiyo-san is still very helpful."

"certainly!"

Creating life out of thin air? Shuimu didn't have such an arrogant idea!

Saving others' lives with his own? Shuimu is not that selfless yet!

Apart from the Rinnegan's Outer Path, the Rinnegan's Natural Technique, it is the only forbidden technique that can truly bring the dead back to life. It is not restricted by bloodline limits and is truly a perfect reference material.

Mizuki had also studied Nagato's Impure World Form, but the Yin-Yang Escape of the Rinnegan was more like an instinct, and Nagato was simply unable to analyze it himself. Nagato's Impure World Form, who was already dead, could not use the Gaiden Rinnegan Technique, so the research on Yin-Yang Escape was progressing very slowly.

Fortunately, I got the reincarnation of Grandma Chiyo not long ago. I didn’t expect to make a discovery in just a few days.

"Kisei Tensei can give life to lifeless puppets and save Gaara. There are two problems here..."

Kouji said.

"Can the puppets of 'father' and 'mother' awakened by Kisei Tensei really awaken the souls of Scorpion's parents? Is the resurrected Gaara still the same Gaara as before?"

“This is really a topic worth discussing…”

Shuimu pondered for a long time, then answered seriously.

"I think that Chiyo developed the reincarnation technique not to make a moving puppet to please Scorpion, but to truly revive the souls of his parents! Similarly, Gaara must have been truly resurrected, otherwise, what's the point of creating a 'copy' of Gaara that she imagined? But if that's the case, then it means..."

"It means that Jisei Reincarnation can call back the soul of the Pure Land, but this forbidden technique based on medical ninjutsu does not have a psychic effect..."

If there really was a power similar to the Impure World Reincarnation, which could summon dead souls from the Pure Land to the Ninja World and then revive them, this would undoubtedly be ideal, but the Jisho Tensei does not have such a function.

"If that's the case?"

Shuimu really couldn't figure out anything.

"It's very simple. First, we need to figure out what is the core of life? The body... No, to be precise, it should be the carrier, or the soul. Which one is more important?"

"Soul!"

If it is a world where supernatural powers in the previous life are not obvious, then there is no doubt that the body is important. If the body dies, then it is truly dead.

But it is different in the ninja world. The importance of the physical body is greatly reduced. For a genius like Orochimaru, changing bodies is just like changing clothes. Mizuki really doesn't think the physical body is so indispensable.

"You are wrong! The body and the soul are equally important!"

“Nonsense!”

Shuimu would not agree with this point of view. If this were true, the problems in this world would be incredibly troublesome.

"If the two are equally important, do you know what the consequences will be? If one of the body and soul of a life is not completely dead, it means that it is not completely dead. How is this possible?"

What is the point of the Pure Land if there is no death?

How does life deal with itself?

What exactly is the ninja world where the sun shines and everything is nurtured?
