In front of Duran were three students, two boys from the Uchiha family, and one was his eldest apprentice, Kazeka Xiaoxue. Since www.biquge.info he has taught himself, he can't favor one over the other, even if Xiaoxue's talent is not good, he still receives the same education.

Now the three of them are refining the chakra while listening to Duran's lectures.

Chakra is derived from the fruit of the sacred tree, which is later contained in the human body, and ninjas need to practice hard to integrate mental and physical strength to stimulate the power of chakra in the body.

So one life is two, two is three, and three is ninjutsu. One is the sacred tree, the second is physical strength and energy, and the third is chakra, which is the same for ninjutsu all over the world.

"The third is the cooperation of two, and the embodiment of two is one. "Everyone in the world knows that beauty is beautiful because there is evil, and everyone knows that good is good because there is evil." Therefore, it doesn't matter if you have shortcomings or deficiencies in the process of cultivation, with these you can know your own strengths. "Remember not to refine chakra for the sake of refining chakra, chakra is just a means to your ends, think more about your goals. ”

Duran also wondered if his three apprentices could refine a chakra that was different from his education.

The chakra of the Divine Tree is just a concept, and it does not limit the situation of the chakra, so adding other things in addition to physical strength and energy can also become a different chakra. For example, if you add natural energy, then it is an immortal chakra.

If you can add others, there may be a new chakra, and these lessons are in the hope that students will be able to have an epiphany from the book and think of other powers.

For example, the breath of the abyss, the spirit of the mountains, the soul of animals, the color of plants, and even the god of stars, the spirit of the sun and the moon, and the root of existence.

Immortal Chakra only uses a small amount of natural energy between heaven and earth, and only in places like Miaomu Mountain and Dilong Cave can the natural energy become the cornerstone of Immortal Chakra, which is obviously unscientific, Duran does not believe that the natural energy in other places cannot make people practice Immortal Chakra.

Of course, adding things to the chakra is only with the help of external objects, and Duran hopes to allow students to change them at the root by learning this very reasonable knowledge.

For example, to reforge their psychic powers, or to change their bodies through epiphany, to change chakras from a more fundamental place.

And to Duran's surprise, it seems that it really can. The state of mind of a person can completely change his mental state, and among the three, Uchiha Itachi can be said to be the most talented, and he can be called a demon, so as he learns deeper, his understanding of what Duran said is also the deepest. The Great Dao is natural, the heaven and the earth are the same, Uchiha Itachi is completely different from before, and his spirit is undergoing a transformation.

If Itachi's spiritual power is a heavenly sword, then Duran's teachings are a whetstone.

A few months later, when Uchiha Itachi was refining Chakra to use ninjutsu, the flames of the Ho Fireball Jutsu suddenly turned cyan.

The flames were blazing, the heat was blazing, and the destructive power of the cyan fireball was beyond imagination, and the trees and rocks turned into ashes when they touched it. Everyone was dumbfounded when they saw the Uchiha Itachi's mutated fireball technique.

Duran's eyes lit up, but he could be regarded as a result, and he only relied on his mouth to give birth to a new power in this world. But this is not the result of Duran alone, the main thing is that Uchiha Itachi has a good understanding, and Duran's education is just a catalyst. Although Itachi was only four years old, he already had the style of a grandmaster, far more mature than adults ten or even twenty years older than him.

However, seeing such a change in his ninjutsu, Uchiha Itachi couldn't help but be amazed. Zhishui asked him what he did and how he did it, and he didn't know it himself, because what he did was no different from what he usually did, why did he suddenly turn into a cyan flame without any warning?

"How are you feeling?" asked Duran.

"It feels very strange, it seems that my understanding of the world is clearer, I see things more thoroughly, and all the confusion of the previous period is gone. Uchiha Itachi said strangely, "And I suddenly understood a lot of the truth you said, Teacher. ”

"It's not all of a sudden, it's that you haven't stopped thinking about it, and today you've finally figured it out. "I'm glad to be a teacher, you're the first to comprehend this brand new chakra. "Actually, Duran doesn't know if he can do it, but since Uchiha Itachi has done it, it shows that his whimsical idea is still justified, but the requirements for human talent are extremely high.

Now it's time to name this new chakra, let's call it 'Pure Green Chakra'. Simple and straightforward.

Xiaoxue was dissatisfied: "Master, aren't you a self-proclaimed great writer, why are you so straightforward in your name." The name is too watery. ”

"I think it's very good, it's the same color as the ferrez's flame, it's simple and easy to remember. Zhishui thinks it's good: "It's just a name, it's just a code name, and if you are too persistent, you will fall to the lower level." "And the teacher also said that if there is a lack of great success, the new chakra of the ferret is an unknown power, and it is better to take an ordinary name to continue to develop. ”

Look at this child to be smart, what he learns is used in life.

Uchiha Itachi's chakra changes were naturally impossible to hide from their parents, and they were all taken aback. Originally, they objected to them apprenticeing to Duran, but later they reluctantly agreed considering Duran's growing prestige in the village, but they didn't expect that the chakra of Uchiha Itachi had undergone earth-shaking changes in just a few months, and it was even richer than the results of their hundreds of years of learning, and they were not calm.

Just looking at the destructive power, the pure green chakra is several times that of the ordinary chakra, and the destructive power is what the Uchiha family has been pursuing. So they immediately asked Uchiha Itachi to tell them the method of cultivating pure green chakra, and they also thought that Duran had taught different refining methods to give Uchiha Itachi new powers. But in fact, Duran is only responsible for lecturing and teaching, and there is no special refining method at all, only Uchiha Itachi's talent against the sky.

However, since there are ninjas who can learn to master the powerful new chakra, it is only natural that some people will follow suit, because no one will think that they are inferior to children. It can only be said that these people are also confident enough.

And the content of Duran's lecture written by Uchiha Itachi has become a secret book of martial arts for the Uchiha family, and many people have begun to read hard behind closed doors, hoping to understand the power of Uchiha Itachi.

Although the martial arts cheats are not passed on, the new chakra of Uchiha Itachi can't hide it at all, and for a while, Konoha Village knows that he is a super genius who can comprehend new powers at a young age, and he also knows that everything comes from the strange man Duran.

Seeing that the Uchiha family may become bigger, Hinata Hinata can't stand it, Duran is Hinata's stepfather, but it can be seen that Duran only teaches the children of the Uchiha family and not the Hyuga family, isn't this partial?

Duran said that the Hyuga clan had no school-age children, and Hinata and Ninji were still young and had no chance to teach.
