This is also the reason why he made a deal with Nagato, because Yin Yang Dun can improve and replace all his ninjutsu systems.

Not only can it be used as a clone, it can also be used in medical ninjutsu.

His medical ninjutsu has been added to the senjutsu system of the Shiggou Forest. If the yin-yang escape that creates life is integrated into it...does it mean that severed limbs can be reborn?

Or, can it further delay aging and increase lifespan?

In Shiraishi's view, this is something that has great potential.

The reason why Ruri and Ayane's bodies have remained at the age of eighteen or nineteen is because of his magic, which delayed the aging of human body functions and kept their appearance youthful.

For women, aging may be the enemy.

But this kind of youth is actually time-limited and cannot be superimposed forever.

In the final analysis, Shiraishi has not yet reached a higher level in his exploration of life.

His medical ninjutsu can only be used to connect severed limbs without seals. If the fatal part is damaged, he will still die.

But now that there is Yin Yang Escape, it's different.

According to Shiraishi, Yin-Yang Escape is the secret technique of exploring life.

Create something out of nothing, create life... If you can combine it with his magic, you can live forever... It is theoretically possible.

Of course, this is only theoretically, the power of the technique has been achieved, but the human body has its limits.

To be honest, if you abandon the natural energy and chakra, the creatures in the ninja world are actually very fragile.

The essence of human beings is that they are still borrowing external forces to change themselves, constantly accumulating the burden of magic, and sooner or later they will be backlashed.

In Shiraishi's opinion, this kind of thing also follows the laws of nature.

But thinking of immortality, Shiraishi thought of the immortal Kakuzu who was working as a debt collector at the Shion Flower Merchant Guild.

The opponent is a ninja left over from the Warring States Period.

The ninja of his generation, Senju Hashirama, was dead, and Uchiha Madara survived, but he was also a withered old man, becoming old, weak, sick and disabled.

But the power of time has not worked in all directions.

The local resentment in Kakuto can be preserved over time by constantly exchanging fresh hearts.

But in Shiraishi's view, this is still a way to capture life force to maintain body functions.

Shiraishi has studied Kakuzu's body and found that all the life sources of Kakuzu are on the tentacles of the Earthly Resentment.

It can be said that Kakuzu is no longer a human being, and his example cannot actually become a universal example.

Di Yu Yu is also difficult to copy.

Playing with the art of life will sooner or later be counterattacked by the art of life... Shiraishi, who used the art of spiritualization to cut his own soul and create a soul clone, can be said to be the most rigorous explorer of the art of life in the ninja world.

One of the ninjas.

Yin Yang Release can not only strengthen the soul clone and increase the medical ninjutsu, but it is also a good medicine for Shiraishi to expel the backlash of the spells from within the body.

Needless to say, exploring immortality, Shiraishi had the idea a long time ago. He is not yet thirty years old, and he is not yet old enough to lament that time is fleeting.

"Yin Yang escape is also a technique based on chakra. Sure enough, my initial guess was correct. Let's give it a try... If it works, things will be more interesting than imagined."

Many sciences in the ninja world are based on chakra and natural energy.

If you want to explore faster and more conveniently, you cannot do without the study of techniques.

Chakra and natural energy are only the foundation, while magic is a tool used to better explore science.

The advanced knowledge related to chakra and natural energy can actually be explored very limited using existing scientific instruments.

For example, when it comes to the level of soul and life, spells are often required to construct and maintain them.

The goal of the experiment is already there.

There is a very deep color in Shiraishi's eyes.

He walked to the glass cylinder on the side. There was a human body growing inside. It was just an irregular human body, or to be more accurate, it was an embryo. His bones and flesh were still in their embryonic form.

But Baishi felt a gaze staring directly at him.

This gaze comes from this unformed embryo.

"It seems that I have gained the preliminary wisdom to distinguish the world. It took shape a little faster than I thought. Yin Yang Escape. That guy Nagato really gave me a great gift..."

If Nagato hadn't come to negotiate Yin Yang Escape, I'm afraid it would have taken him at least ten years to make up for this gap.

Yin Yang Escape opened a convenient door for him.

The role of these clones is not only to improve combat capabilities and protect one's own life safety, but in essence, they are also the pathfinding stones used by Shiraishi himself to explore the science of chakra and natural energy.

"I really want to see you take shape soon..."

The Yang clone is Shiraishi's last clone.

It also means that Shiraishi's science of exploring chakra and natural energy has temporarily reached its end.

But Yin Yang Dun has paved the way for him again, and on this road, Bai Shi will feel that he can go further.

After Shiraishi finished murmuring these words, the embryo inside the glass cylinder suddenly started to squirm, its small red eyes narrowed, shining with a mysterious blood-colored light, and spread out in the solution inside the container.

"Don't worry, it's not the time for you to be born yet. As a 'Ninja Killer', I have high expectations for you..."

This might be his trump card to deal with Nagato's samsara eyes.

Prepare for a rainy day, this is Shiraishi's favorite thing.

Shiraishi doesn't like the word "always victorious". No matter how powerful a person is, he will fail one day.

Therefore, fully preparing various means is just to increase the winning rate.

Although he has very high confidence in his unborn Yang clone, there are many secrets hidden in the ninja world, and the Samsara Eye should not be underestimated.

Therefore, no matter how many white stones come to you, you will not be dissatisfied with means.

"Teacher Shiraishi."

The door was pushed open, and Lin's head appeared on the other side of the door.

Although this laboratory is relatively secretive, Lin is allowed to enter it at any time.

"What's up?"

"I have some questions I would like to ask."

"Have you encountered any difficulties?"

"Yes."

"Okay, I'll be there right away."

After hearing this, Lin nodded. Just when she was about to exit, her eyes met the blood eyes of the embryo in the cylindrical container, and her body couldn't help but tremble.

How should I put it? It's strange.

It was obviously still an embryo, but it gave Lin a very dangerous feeling.

The Nanao in her body was also roaring something extremely violently. This feeling was like encountering a natural enemy.

——This thing is more terrifying than Wood Release and Sharingan. What is your teacher creating?

Nanao said these words to Lin's body.

That chilling aura was conveyed through the blood eyes, making Nanao unable to remain indifferent.

It is clear that he does not have the power of the Six Paths Sage, nor does he have the limit of blood inheritance. In the final analysis, he is just a mortal who learned senjutsu by luck... However, the embryo is more frightening to Nanao than Sharingan and Wooden.

Lin knew that it was the Yang clone created by Shiraishi.

It's just that compared to the past, the Yang clone has undergone some earth-shaking changes.

However, this kind of thing is not something she can interfere with for the time being. It is obvious that Shiraishi has given the Yang clone a more powerful spell system.

Lin felt relieved when she thought that Shiraishi seemed to have mastered Yin Yang Escape recently.

It's probably because of the Yin-Yang Escape technique that it became so terrifying.

After Lin left the room, Shiraishi didn't stay long.

The road paved by Yin Yang Escape, don't rush for the moment.

Only after the Yang clone is completely formed can he determine how 'accurate' his guess is.

After staying in front of the container for a while, Shiraishi left the laboratory.

Staring at Shiraishi's back, the embryo in the container closed its pair of bloody eyes that could see through the essence, fell into a steady and powerful breath, and fell asleep.

Yuyin Village.

The never-ending rain of sorrow.

Sitting on the rain platform of the high tower, with her long red hair hanging down, her samsara eyes, which have lost all emotions and desires, are looking down at the entire Yuyin Village with incomparable indifference.

After many years, Amegakure Village has gradually regained its vitality. Business, ninja schools, and various people's livelihood problems have gradually improved due to the assistance of Orochimaru and others.
