Liuri went to the Naruto Building and it didn't take long to return home again.

When he came back, Shiraishi saw Liuli holding a scroll in his hand and threw it to Shiraishi.

"Thank you."

Shiraishi was not pretentious either, so she caught the scroll directly.

"Just study the magic quickly."

"This kind of thing is really a bit difficult. After all, there is too little information about immortal arts. Even if it is a reference, if there is a system of immortal arts in the three holy places that can be studied, it will undoubtedly be of great help to my work."

"Give up. If you hadn't signed a psychic contract with the three holy places, it would be difficult to find there, let alone obtain immortal arts from there."

"So, Sannin is really a unique ninja."

The three ninjas of Konoha have close ties with the three holy lands, and this kind of rumor has long been common.

Not only is the disciple of Naruto, but also the three holy lands behind him. For ordinary ninjas, they are beyond the reach of the world for the rest of their lives.

"But even the three ninjas, I have never heard of them successfully practicing immortal arts."

"Of course, I don't know if the immortal arts practiced by the psychic beasts are different from the immortal arts I studied, but the fusion of natural energy with ordinary chakra does have considerable risks, and it may be a death."

Shiraishi sat down in the room, took a sip of tea, and then spread the scroll in his hand.

The beginning of the scroll records the developer and name of the ninjutsu.

The art of spiritual transformation.

Developer's previous generation Naruto Tobirama.

According to records, the art of spiritual transformation is a way to allow the soul to leave the body, and to shuttle ignoring the distance and directly kill the enemy.

However, after the soul leaves the body, the spirit body will retain the consciousness of the caster. Therefore, this kind of ninjutsu is very useful and can not only be used in combat, such as transmitting intelligence, large-scale perception, or even transmitting chakra to companions. All spiritual techniques can be accomplished.

I have to say that the predecessor Naruto Senju Tobirama who developed this ninjutsu was a respectable figure.

It was a pity that I heard that I had sacrificed myself on the battlefield of the First Ninja World War.

Shiraishi agrees with many of the previous Naruto's thoughts.

Build a ninja school, set up an antebellum organization, differentiate and suppress the ninja clan, enhance the status of civilians, and create various secret techniques and ninjutsu belonging to the Konoha school... He is all in politics, science, and military fields, and he was the first to create and was imitated by ninja villages from various countries.

The era of one country and one village was created by the Chiaju clan and the Uchiha clan, but this system is actually just a famous and has little content. If it weren't for the previous Naruto Tobirama, the so-called ninja village... Think about it carefully, it is no different from the war-torn pattern of the ninja clan separatist side in the Warring States Period.

It was not until the previous Naruto took office and carried out a series of epoch-making reforms that this abnormal pattern of the village ruled by the ninja tribe gradually changed to a better place, using the civilian class to restrain the ninja tribe. Since then, Konoha has formed a stable balance, restraining each other, and relying on each other.

The balance means make people feel ashamed of.

The only shame is that there is no follow-up.

With the outbreak of the first Ninja World War, the previous Naruto Senju Tobirama passed away. Even if he still had unfulfilled ambitions and ideals in his heart, he could only go with the wind and entrust the future of the village to the current third Naruto.

As for the third generation of Naruto, Shiraishi didn't know much about it. It may be because the previous generation of Naruto was ahead, which led many people to ignore the actions of this third generation of Naruto.

After all, many systems have been perfected during the Naruto period of the previous generation, which has led to the fact that future generations can't surpass the previous generations. Therefore, we can only look forward to what amazing things will happen to the third generation of Naruto in the future.

After thinking about this, Shiraishi returned to the underground laboratory with the scroll of the Technique of Spiritualization.

He has injected natural energy into the experimental body and it takes some time to observe and collect data.

Then, it's time to consider the issue of the "Cage Bird" curse seal.

Shiraishi has actually been studying the cage bird for a while, but due to the lack of data and the deeper structure of chakra that has not been fully analyzed, the progress in this area has stagnated for a long time.

According to Ayane, once the cage is carved, it will follow for a lifetime and will only be eliminated when it dies.

In other words, the cage bird can be relieved under the condition of "death".

So, what is the state of "death" in death?

Body or soul?

What characteristics does chakra have been given in this?

People are born with chakra, and if they lose chakra, they will die.

If Ayane is trapped in a state of death with chakra exhaustion, will the cage bird be eliminated?

Of course, this kind of death is not real death, but a fake death state similar to death.

Then he repeatedly assigned Ayan Chakra to wake her up from her fake death.

The prerequisite for doing this experiment is to first verify a point of view.

That is, will people really die after losing chakra?

If a person loses chakra, it may not necessarily die, then...how did chakra come from?

Why has it become the energy of life activities necessary for human survival?

Is the death of losing chakra a physical death or a soul death?

Can humans enter a very wonderful state of false death after losing chakra, and come back to life after re-giving chakra? Can this happen?

If all of these can be confirmed through experiments, then eliminating cage birds is likely to be no longer a problem.

It also solved many of the doubts in Shiraishi's heart.

Shiraishi carefully recorded these guesses one by one on the laptop she carried with her.

As for science, you can guess first if you have questions, and then you can argue whether it is right or wrong.

Therefore, the study of soul ninjutsu is very necessary.

The only troublesome thing is that it is the era of war, and he may go out to perform tasks at any time, resulting in no time to conduct experiments here.

Listening to the strange shouts from the experimental subject on the operating table, I was in a state of pain. I couldn't make a sound if I wanted to scream. I clearly felt that my throat was about to be shouted, but I could only hear the slight sound of myself struggling on the operating table.

Shiraishi calmly looked at the experimental subject who was spasming his body on the operating table and was distorted and painful. He had no emotions in his eyes. He skillfully moved and cut off a piece of the epidermis eroded by natural energy. The epidermis appeared light green, put it in a vessel, and observed with a microscope.

Then, looking at the computer's light screen, which timely displayed the heartbeat frequency of the experiment on the operating table and the fluctuation value generated after the fusion of natural energy and chakra.

These experimental subjects went from being uncooperated at the beginning to being played with dolls with numb expressions, and they didn't even have the feeling of fear in their eyes.

Shiraishi said that he was a little wrong with this.

Unexpectedly, after natural energy merges with chakra in the human body, it will cause such a terrible mental and physical impact on the person involved.

Therefore, whenever an experimental subject shows signs of collapse in spirit, stop the experiment in time, prescribe a pair of calming drugs for him, and exchange it for another experimental subject.

This repeated sustainable use can also be considered a cost-effective way.

Shiraishi looked at the other people trembling by the wall and shook his head. It's true that these guys had no energy to devote themselves to science at all.

If his experiment can be successful, these people can suddenly turn from ordinary people into ordinary people with fairy chakra in their bodies. Although they don’t know any ninjutsu, their vitality, strength, speed, and reaction will all increase qualitatively.

I dare not say anything else, longevity should be no problem.

As for immortality... Shiraishi had no choice but to think about it, the more he thought about it, the more he became more outrageous.

"The research on natural energy is almost done here. The immortal chakra needs to further deduce data to improve the success rate of fusion. Next, we can focus on dealing with the problem of bird curse seal in the cage..."

Hum? Wait!

Shiraishi suddenly discovered a very serious problem, that is, how can he collect detailed physical data from Ayen's current state.

He is currently living in the Uchiha tribe, and Ayan is a Hyuga tribe ninja.

If Ayano brought over and was accidentally discovered by Liuli...

A trace of cold sweat broke out on Bai Shi's face.

Hurry up and calculate what your survival rate will be after being discovered?
