Naruto's strongest shock

Hongdou didn't feel any discomfort or pain, and even completed the second stage very comfortably, but it was still unbearable for other people.

After another experiment failed, Yu Naito sighed and shook his head.

"It looks like it really isn't that easy to succeed. Hongdou, you are really special."

Saying that, Naito Yu touched the little head of Hongdou who was standing aside.

Hongdou is now very familiar with Naito Yu, and she is no longer so in awe, but looked up at Naito Yu with a smile, and said: "Of course, I am the person Yu Naito-sama likes."

"..."

Yu Ye always felt that this sentence was a bit weird, but he didn't say anything.

Naito Yu called this transformation of himself the transformation of a fairy body.

If he can complete five transformations in a row, he should be able to reshape the immortal body and achieve a physique similar to Naito Yu's. Of course, this is too difficult.

Even the second stage of transformation was only successful on Hongdou, and the future is even far away.

After going through the second stage, Hongdou's strength has taken another leap, directly approaching the level of jounin, and stepping into the level of jounin in one fell swoop. If she is not too young and has too little mastery of ninjutsu, she even has the elite level of ninjutsu. Tolerance is not impossible.

It is obviously impossible for Anko's talent to be compared with Kakashi's, but after these two stages of transformation, he has already caught up with Kakashi's footsteps.

Orochimaru didn't pay much attention to the disciple Ando at first, he just treated it as a temporary assistant, but after two transformations, Orochimaru was very surprised.

Originally, he really wanted to study the red beans, but Naito Yu directly warned Orochimaru not to think about the red beans casually, so Orochimaru could only honestly give up, and at the same time felt helpless.

Whose disciple is Hongdou?

In the following time, Naito Yu did not continue the third stage of the experiment on the red bean, because the research of Orochimaru finally achieved results, and this result attracted Naito Yu's incomparable attention.

The deepest connection between Chakra and the soul was found by Orochimaru!

Naito Yu has long known that Chakra and soul are connected, body, Chakra, and soul, there is an absolute connection between the three, the connection between body and Chakra is very easy to find, and it does not even need to be found, it exists by itself .

Not to mention the body and soul, if the body and soul are not connected, then this person is already a dead person.

However, the connection between Chakra and the soul is always vague, disconnected, and difficult to find. Although some connections can be deduced according to the technique of spiritualization, it is difficult to touch the core.

And Orochimaru, after continuously researching the chakra and soul of the tailed beast, finally thoroughly found the essence of the connection between the soul and chakra!

The soul is nourished by chakra!

As we all know, once the physical strength and chakra are completely exhausted, it basically means that life has come to an end and one is facing death.

There is a problem here. Physical strength undoubtedly represents the body, and exhaustion of physical strength means that the physical body has no strength.

And the exhaustion of Chakra simply means that the Chakra is exhausted.

But what about the soul?

Why is the soul disconnected from the body because of the exhaustion of chakra and physical strength, that is, death?

The connection between the soul and the body does not need to be studied, the focus is on the relationship between the soul and Chakra, and Orochimaru has been tested and proved that the soul exists in the human body with Chakra as a nutrient.

Once the chakra is exhausted and loses nutrients, the soul will become sluggish, which is why ninjas who have exhausted chakra will feel particularly tired.

If the physical strength is exhausted again, the soul will completely disconnect from the body, leave the body, and be summoned by the undead world, which is death.

Just like the technique of reincarnation, it uses a part of the reincarnated person's body, plus chakra, and when the two are combined, the soul is forcibly channeled back from the undead world.

After getting the research results of Orochimaru, Naito Yu completely cleared away the clouds and mists about many things, and only felt that everything was clear.

The soul takes chakra as nourishment, and the way to strengthen the soul is very simple, that is to nourish it with chakra, but it requires a special method.

Orochimaru did not study this special method in detail, but it also gave a rough prototype, coupled with Naito Yu's ideas and ideas, and quickly researched it out.

It's roughly similar to the reverse use of Undead.

But at this time, Naito Yu also discovered a problem.

His body, chakra and soul are perfectly combined, that is to say, his own chakra can only nourish the soul, but cannot strengthen his own soul.

To strengthen the soul, you need to devour the chakra of the outside world.

Moreover, the devoured chakra must also be unconscious and cannot have a soul, otherwise the two souls will conflict, resulting in damage to the soul.

The reincarnation of the corpse studied by Orochimaru is because of the forcible suppression and devouring of other people's souls, which caused his soul to be damaged, so that he was directly killed by Uchiha Itachi's illusion in the original work.

Between souls, even if one party's soul is extremely strong and the other's soul is extremely weak, as long as they devour each other, they will definitely be damaged.

Or it can be said simply that two different souls are like fire and water. If you insist on merging the two together, the water will evaporate or the flame will be extinguished.

If you want to devour chakra to strengthen your soul, you must meet two conditions.

The first condition is to be clear about the nature of soul and chakra, and have a method of devouring chakra with soul, that is, secret technique.

The second condition is that chakra must be a soulless, unconscious free chakra, just like the natural energy scattered between heaven and earth, without a soul.

If you can strengthen yourself by devouring the chakra and souls of other ninjas, then the second generation of Naruto Senshoubojian, who also understands the mysteries of souls and chakras, would not be invincible long ago.

Thousand Hands must understand the mysteries of the soul and Chakra. He is the creator of the Jutsu of Reincarnation of Dirty Earth.

With the existence of Senshoujuma, Senshou Feima can get almost any experimental materials he wants, and the tail-grabbing beast is just like playing. The experimental environment is much better than Orochimaru, and it is not surprising that he can master more things.

If you want to find unconscious, soulless pure chakra, the conditions are more stringent.

Any ninja must have a soul, their chakra is absolutely impossible to swallow, and the chakra of the tailed beast can't make this idea either, the tailed beast also has a soul.

Chakra with soul cannot be devoured and absorbed. If it is replaced by other people, I am afraid that there is nothing to do about it. I don't know how to find chakra without soul, but this is not a problem for Naito Yu.

Naito Yu knows more than one kind of pure chakra without soul and consciousness!

Whether it is the dragon vein of Loulan, or the "star" of Xingren Village, etc., these should be free chakras without souls.

In other words, these chakras can be used to nourish and strengthen the soul. For Naito Yu, the strength of the soul is the key to breaking the shackles of the body and opening the seventh or even the eighth door.

Naito Yu didn't know how to strengthen the soul, break the shackles of the body, and open the seventh door of the true eight-door dunjia before, but now, he finally has a clear path in front of him!

The Naruto world has too many power gaps, and Naito Yu seems to be invincible in the Ninja World today, almost surpassing Senju Hashirama and Uchiha Madara back then, but facing the Six Paths Sage, Kaguya Hime Otsuki, who is almost a god-like existence, Still not enough to see.

At the beginning, Senju Hashirama and Uchiha Madara were able to suppress the existence of the entire ninja world on their own, and in the later period of the original book, there appeared a more powerful ten-tailed, six-level class, so Naito Yu would never Stop and keep going.
