Five days have passed since Yu Shirakawa and Madara Uchiha explain their dreams to each other.

These days, Yu Shirakawa's personal life rules have barely returned to their usual normal levels.

It was Uchiha Madara who became more concerned about teaching Shirakawa Yu and his practice was even more harsh.

Forbidden art, secret art, illusion art, physical art, and ninjutsu were all taught to him just like they don’t have money.

Among them, there are not only ninjutsu inherited from Konoha Village, but also Uchiha Madara, the inherited ninjutsu inherited from the other four major villages and small villages.

This made Yu Shirakawa a little stunned.

It’s worthy of being Lord Madara!

He is simply the strongest collector in the ninja world!

There are no ninjutsu and forbidden techniques in the five major ninjutsu villages that Uchiha Madara can't do.

It can be said that during this period, Yu Shirakawa was under great pressure to study.

Basically, he fell asleep late at night, but he himself enjoyed it and tirelessly absorbed all the knowledge.

Even when he went to Ninja School to class, Yu Shirakawa used the Shadow Clan art to help him perfunctorily.

The body is to follow Uchiha Madara to concentrate on learning.

...

Ninja School Library—

Yu Shirakawa traveled through the vast library, and from time to time he reached out to take out basic books from the bookshelf and stuffed them into his hands.

"Ancient Records", "The Myth of Heaven", "The Destiny of the Imperial Sect", "The Origin of the Legend of Chakra"...

"You little kid, what's the use of these things?"

Seeing Shirakawa Yu constantly collecting books about myths, Uchiha Madara couldn't help but frown: "They are just false history and people's wishful thinking."

Upon hearing this, Yu Shirakawa looked up and explained: "Mr. Madara, if you want to understand the essence of power, it takes a lot of research to prove it."

"Even if some of these things are false history, small things are often hidden in this constructed false history."

After all, the strangest group of guys who record history are the guys, and they often like to be a mixed reality.

In the fictional history, real fragments are stuffed into it, waiting for later generations to discover their evil tastes.

Uchiha Madara hugged her chest with her hands, looking thoughtful.

It was not that Yu Shirakawa's words woke him up, but that he remembered the Uchiha family, the stone tablet under the Nanga Shrine, which contained the words left by the Six Paths of Immortals himself.

Before he came into contact with it, Madara thought that the six immortals that spread to the world in the legend, connecting the heart to the heart, were false, and were delusional legends made up by people.

But after Uchiha Madara saw the message on the stone tablet and opened the Reincarnation Eye, he had to believe the existence of the Six Path Immortals even if he didn't believe it.

After finding all the books you needed, Shirakawa Yu said goodbye to his classmates and returned to his home.

With compensation from the big merchants Aima Heiyan and Hinata family, he is not short of money at this stage.

Therefore, Yu Shirakawa opened a small research room underground in his home, which stored a large number of purchased experimental instruments and materials.

Anything related to his research was bought with a wave of his hand.

In order to prevent being discovered by someone, Shirakawa Yu also specially asked Uchiha Madara to learn barrier techniques and hide his underground laboratory.

What surprised Yu Shirakawa was that even though all the technology trees in the ninja world were tilted, computers and computers still existed.

Although it is not very high-end compared to the Internet era in the previous life, some are better than none.

"In myths and legends, chakra is the exclusive power of the Six Path Immortals, but when he established the Ninja Sect, he specially taught it to the world in order to allow people to understand each other and connect their hearts together."

"At this point, the people in the world have the power of chakra."

Listening to Yu Shirakawa reading out the legends in the book, Uchiha Madara sneered disdainfully.

After identifying the stone tablet under the Nanga Shrine through the Manelidid Sharingan, he realized that the origin of chakra did not come from the Six Paths of Immortals.

The true origin of chakra is a sacred tree that runs through the sky and the earth.

At the same time, the first person who owned a chakra was definitely not the Six Path Immortal, but a guy who was called a goddess in ancient times.

After putting down the books about the Six Paths of Immortals and Chakra, Yu Shirakawa looked melancholy.

The reason why he wanted to understand the true nature of chakra was to prepare for the last moment.

Through understanding of the original work, the so-called Ten Tails of the Divine Tree are nothing more than things from the Otsutsuki clan, and even the source of chakra may also be from the Otsutsuki clan in the sky.

Shirakawa Yu's dream and ideal are to go to the top, and in the future, he is likely to face the Otsutsuki clan personnel.

He didn't think that the chakra he mastered could be better than the Otsutsuki clan who had mastered both chakra and the sacred tree for many years.

Those who want to defeat the Otsutsuki clan either have a higher degree of mastery and understanding in the chakra and the sacred tree than they do, or they are looking for other solutions.

The first method is obviously a bit difficult to accomplish and is not very realistic.

To this end, Yu Shirakawa is preparing to find a second way to surpass the Otsutsuki clan from other aspects.

"Yu Xiaogui, do you want to understand the nature of chakra?" Uchiha Madara asked, looking at Yu Shirakawa who was thinking about it.

"yes."

Yu Shirakawa, who came back to his senses, nodded and said, "Master Madara, in my opinion, Chakra is actually a power that is both dangerous and can bring miracles!"

"Danger? Miracle?"

Uchiha Madara repeated these two words.

"That's right, it's a miracle. Chakra can make people use ninjutsu, illusion, sealing, and time-space ninjutsu with various attributes. Isn't this a miracle?"

"You know, lightning, flames, earth, forests, and sea are all miracles and great powers that originally belonged to nature!"

Yuko Shirakawa said seriously, "When dangerous, Lord Madara, do you remember what chakra was extracted from?"

“The mix of body and mental energy ratio.”

Based on his own understanding of chakra, Uchiha Madara naturally couldn't answer wrongly.

"But why can the mixture of body and spirit be able to extract chakra?"

"The life energy of both the body and the spirit is proof that humans can live in the world!"

Yu Shirakawa stood up from the chair, his face full of excitement.

"Suppose that ordinary people who cannot extract chakra have a general life expectancy limit of 150 years!"

"And the ninjas who can extract chakra, because they mix their bodies and spirits into chakra to fight, their daily consumption, what is their general life span?"

"Mr. Madara, you have also said that chakra is a mixture of energy between the body and the spirit, and is born from the cells in the process of refining!"

"But once the chakra is refined, will it wear out on its own lifespan?"

"Where did they go to the upper limit of their lifespan that they could live to during the process of refining chakra?"

"Mr. Madara, if this proof can be successful, then Chakra undoubtedly uses human lifespan to obtain the dangerous power of power!"
