Reborn Naruto, I rolled my eyes to the sky

According to Orochimaru's theory and explanation, Minato stretched out his right hand, circulated the chakra and gathered it in his palm, and a faint blue light slowly took shape, but before we could take a closer look, Minato disappeared in front of us in a flash.

After a moment, he returned to us, and almost at the same time, an explosion was heard not far away. It was Minato who felt that the chakra in his palm was difficult to control stably, so he used the Flying Thunder God Technique to throw it out.

Minato moved his palms and smiled bitterly: "It is indeed difficult to gather chakra outside the body stably. It seems that it will take some time to study it."

Although Jiraiya and Tsunade are also powerful elite jonin in Konoha, the development of ninjutsu is not their forte, so it is mainly Orochimaru and Minato who discuss and research it.

"It is indeed difficult to keep chakra stable outside the body, but in addition to the puppeteer's chakra threads, our Hyuga clan also has unique skills." I sometimes discuss this with Minato.

"You mean..." Although the Senju clan that Tsunade belonged to has been dispersed and integrated into Konoha Village, compared to the commoner origins of Jiraiya and Orochimaru, Tsunade still knows a lot about the secrets of Konoha's wealthy families.

"The Hyuga clan's secret Bagua Palm - Kaiten, is said to use chakra to form absolute defense outside the body, but isn't this the Hyuga main family's secret ninjutsu?" Tsunade glanced at my forehead protector. She should know that I am from the Hyuga branch family, and there must be a caged bird curse seal engraved on my forehead.

"That's right. The specific training methods are naturally the secret of the main family, but the basic principles can be found in the Hyuga clan's library." I replied.

"The key lies in rotation. The basic principle of Kaiten is to eject the unique chakra of the Hyuga clan from the acupuncture points around the body, and then use the rotation of the body to drive the chakra to form a perfect and leak-free absolute barrier."

I continued, "The secret of the main family is the so-called Bagua Palm - Huitian, which was discovered by successive generations of Hyuga clan masters. It uses the least amount of chakra, the least acupuncture points, and the least physical energy to form a relatively perfect defense."

I took a stance, showing the momentum of the Hyuga Soft Fist, and slowly swung my arms: "Of course I haven't learned any of this, but the most perfect defense is actually the one that uses the dumbest method to turn the world around."

My movements gradually quickened, and as the chakra circulated, a thin white barrier formed around me: "That is to release the chakra through the 365 acupoints all over the body, and then control it through the extremely fast rotation of the body to form a perfect ring around the body."

As I moved, my movements became slower and slower in everyone's sight, and the movement around me became smaller and smaller, as if it was still. The white light shield around me also gradually became transparent.

"Huh?" Orochimaru exclaimed in surprise and made a few hand seals: "Fire Style - Rain of Fire."

As Orochimaru formed hand seals, a flame burned towards where I was, but it did not touch the corner of my clothes. Instead, it hovered around me under the influence of an invisible force, like a fire cover.

Seeing that everyone, especially Minato and Orochimaru, seemed to be thinking about something, I shuddered slightly, and the flames around me flew away and extinguished. A strong wind spread in all directions, stopping the demonstration of Kaiten.

"This is my usual Hyuga Gentle Fist training method. Because the preparation time is too long, the consumption of chakra is very large, and the consumption of physical strength is also not small, so there is no opportunity to display it in actual combat."

"But the best way to attack is to point, and the best way to defend is to circle. This training method has made me understand the circle principle of Hyuga Soft Fist, which uses softness to overcome hardness, more deeply."

"Although it is not the same thing as the development of the Rasengan, rotation is indeed a very effective way to control and guide chakra."

"Through rotation, the restlessness of the internal chakra can be restrained, and the interference of external forces on the chakra can be calmed. It should be helpful for the development of this ninjutsu."

Minato looked thoughtfully at the circle formed under my feet when I practiced Kaiten just now: "It is more than helpful. I think this is the key to this ninjutsu."

Minato stretched out his hand and once again circulated the chakra to gather in his palm. As the dark blue chakra gathered, we all watched carefully the result of Minato's attempt.

I saw a ball of chakra slowly gathering in Minato's palm, and it was still slowly rotating under Minato's control, but the next moment Minato disappeared again and threw the chakra in his palm away.

Minato came back and looked at the chakra gathering that was more powerful than the previous explosion. He frowned and said, "It's difficult to control the chakra after it is released into the palm, and it's even more difficult to rotate it stably. But the power has been improved to a certain extent, which is a pleasant surprise."

"Rotation does increase the instability of chakra. The key lies in balance, and guidance after the balance is broken. This requires extremely high precision control of chakra."

"If we can solve these two problems, we can achieve the two goals of forming the Rasengan and only hurting others without hurting ourselves. The development and use of this ninjutsu will no longer be a fantasy."
