Konoha Village, Naruto's house, food payment day.

This time, the Sandaime Hokage not only came to deliver this month's food expenses, but also brought two sets of ninja school textbooks.

"I heard that you want to learn Ninjutsu, so I brought you Ninjutsu school textbooks. As promised in advance, I will be able to teach you Ninjutsu on this day." The Sandaime patted the pile of textbooks. Seriously.

With the Sandaime's step-by-step explanation, Hideyoshi and Naruto also had a clear understanding of the study of Ninja School.

Ninja School, the full name of Ninja School, has five main categories of courses: theory, exercise, experience, history, and practice.

The old man Sandaime is only responsible for training and experience. Theory and history rely on self-study. In practice, the two can only improve each other by fighting against each other.

The old man Sandaime clearly said that he would not talk about history, and then he talked about the will of fire history class in front of Hideyoshi for an hour, and then slowly entered the exercise class and said:

"Chakra is the basic energy for performing ninjutsu, genjutsu, and taijutsu. The first lesson for any ninja is to learn the art of chakra refining."

Just when Naruto was already drooling, Hideyoshi began to observe when Naruto's eyes closed. The Sandaime Hokage said in his unique sleeping voice: "Today, I will guide you in the practice of chakra extraction."

Upon hearing this, Hideyoshi immediately elbowed Naruto at the same table. Naruto shook his whole body and said loudly: "Yes, we must study hard."

The Sandaime Hokage was not surprised. After all, his three disciples, Jiraiya, Orochimaru, and Tsunade, were all like this.

After the Sandaime patiently explained it, Hideyoshi felt that it was really not difficult to get started with the Chakra Refining Technique. It sounded like a special breathing meditation method.

Even if the steps are wrong, it will only affect the effect of the chakra refining technique, but will not invalidate it.

Hideyoshi suddenly realized that a child of several years old in the original novel could use it, how could this thing be difficult?

I learned from the Sandaime Hokage that there are three sources of chakra. One is the physical energy in human cells, the other is the spiritual energy obtained through chakra refining techniques, and the third is natural energy. This is a special situation.

It can be seen that the essence of Chakra Refining Technique is a method of exercising spiritual energy. In addition, it is also a method of using Chakra.

Naturally, the Sandaime Hokage will not wait for Hideyoshi and the others to develop the chakra of mental energy. Today, he will just let them learn to use the chakra of physical energy.

Within about half an hour, Naruto showed an excited smile.

"Grandpa Sandaime, do you think this is chakra?" Naruto said excitedly as he stretched out his hand.

The Sandaime Hokage smiled, held Naruto's hand to confirm, and touched Naruto's head.

"Naruto-kun is a genius."

As expected of the Nine-Tails Jinchuuriki, the amount of chakra must have exceeded that of an average jounin.The Sandaime Hokage sighed.

At this time, he looked at Hideyoshi, who had a strange look on his face from the beginning, and asked aloud: "Did Hideyoshi-kun encounter any trouble in practicing the Chakra Refining Technique?"

After listening to the Sandaime Hokage's explanation, Hideyoshi felt that it was very easy to get started and he could master it in just one practice, faster than Naruto.

But it was a bit weird after practicing, it was not the feeling that the Sandaime Hokage said, and he was struggling with whether to confess his situation to the Sandaime Hokage.

According to the Sandaime Hokage, chakra is extracted from human cells. As the chakra refining technique is activated, one feels the cells in the whole body move and the body heats up slightly.

The refined chakra gathers quickly along with the blood, and at this time I will clearly feel the newly refined chakra.

When the chakra refining technique is stopped, unused chakra will disappear spontaneously.

Instead, Hideyoshi's chakra slowly gathered along with his bloodline, and he could also control it.It is not like the Sandaime Hokage said that chakra will disappear spontaneously after being refined, but it will "remain" in the body.

The specific situation cannot be described, but Hideyoshi can feel that his chakra "remains" in his body in another form.

Hideyoshi guessed that this should be the influence of Saiyan blood, but the Sandaime Hokage asked him, so he still explained the situation clearly and let professionals answer it.

The Sandaime Hokage chuckled: "Don't forget your unknown blood inheritance limit. Relax your mind and body, don't be nervous, let me see your situation."

After the Sandaime Hokage finished speaking, he placed one hand on Hideyoshi's belly to feel the chakra flow throughout Hideyoshi's body.

Well, the total amount of chakra is quite ordinary, better than civilian ninjas, the Sandaime Hokage thought to himself.

"Hideyoshi-kun, try refining chakra now."

When Hideyoshi heard this, he started running the chakra refining technique.

The Sandaime Hokage continued to observe the chakra in Hideyoshi's body. Hideyoshi was right, it was gathering very slowly.

Hideyoshi-kun has now stopped the chakra refining technique.

Why did his chakra not disappear slowly, but spontaneously integrated into Hideyoshi's body? The Third Hokage was amazed.

Ninjas are refining too much chakra, so in order not to waste it, they will attach it to their fists and feet to enhance their attack power. However, ninjas who have not been trained will allow chakra to attach to their internal organs, causing waste.

The act of attaching will also consume chakra, which is what the Sandaime Hokage calls disappearance.

The Sandaime Hokage touched his beard, what is going on?
