The medical technique was discussed for almost a week, and Tsunade felt that it was almost over, although she really wanted to continue, after all, she still had to teach Sun Moon medical ninjutsu. Pen, fun, pavilion www. biquge。 info In addition to discussing knowledge with Tsunade in the past half month, his doppelgangers have not been idle, continuing to practice the moon flash and launching the gossip empty palm with his fingers, and the white eye exercise and listening to the voice debate have not been left behind.

"Sun and Moon, today I officially taught you medical ninjutsu!" Tsunade said to Sun Moon with a smile.

"Yes, master. "The sun and the moon have been waiting for this day for a long time.

"I communicated with you for so long a few days ago, and you also know that in addition to the five basic attribute changes, Chakra also has Yin and Yang attribute changes. 'Yin' refers to the changes in the chakra that are dominated by spiritual energy, while 'yang' refers to the changes in the chakra that are dominated by the physical energy. ”

"Your Hyuga family's chakra is generally attributeless, although there are no five attribute changes, but it can produce yin and yang attribute changes. Because although the yin and yang changes of chakra are difficult, they are linked to the fundamental nature of chakra: the essence of 'chakra is a combination of spiritual energy and physical energy' will not change. ”

"The so-called yin retreat is the use of spiritual energy to create a material image from 'nothingness'. For example, the Nara clan's [Shadow Imitation Technique] gives a shadow entity that has no substance. Yang Dun, on the other hand, uses the energy of the body to inject 'chakra' or 'will' into 'matter', so that it has a similar vitality, which is simply to inject life into the material image. For example, the medical ninjutsu and the [doubling technique] of the Qiu Dao clan belong to Yang Dun. ”

"Well, you told me, master. Sun and Moon said that this chakra theory is somewhat similar to the Tai Chi Yin and Yang theory, so Sun and Moon are easy to understand.

"And the basis of medical ninjutsu is the change in the nature of chakra yang. For example, using the yang attribute chakra stimulates the cells of the injured person, so that the cells can accelerate the division and growth, so as to achieve the purpose of healing the wound; injecting the yang attribute chakra with a large amount of body energy into the cells can make the damaged and dead cells quickly activate, and the cells repair and rejuvenate themselves; release a large amount of yang attribute chakra, so that it flows in the body, so that the cells can divide and regenerate rapidly, and can even directly inject vitality into the patient's injury!"

"So medical ninjutsu requires very precise chakra control. Chakra is not well controlled, which can lead to cell rupture and death. If the chakra is too slow to act on the cells, the recovery is too slow. It works too fast and is prone to mistakes. You have to be able to control every chakra as you like!"

"I understand, master!" Sun Moon nodded, the precise operation he liked the most.

"Alright, now let's practice chakra's yang nature change first. Tsunade began to teach the sun and the moon.

Ninja's control of chakra is divided into several types, the more basic ones are: controlling the dosage, flow, distribution, characteristics and functions of chakra, etc., and the advanced control skills are the changes in the form of chakra and the changes in the nature of chakra. For example, the chakra needle used in the Sun Moon Soft Fist point is a simple change of chakra.

To make the chakra appear yin and yang changes is to make the extracted chakra show the nature of 'physical energy' or 'spiritual energy', which belongs to the advanced nature change of chakra.

The change of yin and yang has a certain relationship with the mixing ratio of the two energies in the chakra of the person itself. Due to the individual differences of people, some people have strong physical energy, such as Dingza, and his chakra has slightly more physical energy than spiritual energy, and chakra is a partial yang attribute. And some people have strong spiritual energy, such as Lu Jiu, who is the opposite, and his chakra has more spiritual energy than physical energy, so his chakra is yin. Just like Tsunade Ji is a thousand-armed clan, she has a strong vitality and physical energy, and she will get twice the result with half the effort when she uses Yang to escape.

Because of the time traveling, the sun and the moon have reincarnated eyes, and his spiritual energy is stronger than ordinary people. On the other hand, the immortal body of the sun and the moon has a strong vitality, and the body energy is far beyond that of ordinary people, so the chakra of the sun and the moon is basically neutral, and the mixture of the two energies is quite even.

The self-condensed chakra, if the spiritual energy and physical energy in it are exactly in equal proportion, it is the best, such a chakra is not only relatively pure, but will not be biased towards any one attribute. Moreover, after turning on the [Immortal Mode] and integrating natural energy, it is also very beneficial for the Immortal Chakra to perfectly achieve a 1:1:1 balance between the three.

When a person uses ninjutsu, there is as much mental energy as the physical energy consumption in the chakra. When using illusions, the energy mix of the chakra is still five to five, but the spiritual energy in the chakra is consumed more. Physical arts, on the other hand, consume more energy in the body. The chakra five-five ratio is not easy to deviate, and the technique can also exert greater power.

So all Sun Moon has to do now is to extract the chakra at the same time, so that the chakra can show strong physical energy. It wasn't difficult to do this, and Sun Moon quickly found the trick, which was to feel the feeling of vitality in the chakra with your heart, which was a feeling of vitality, jumping, and growth, and then release it. On the other hand, the yin nature changes, and the heart has to try to feel the spiritual power in the chakra, which is a feeling full of spirituality, radiance, and will, and then release it.

This is the same as Naruto's practice of the change in the nature of the wind attribute chakra, to feel the lightness, flow, sharpness, thinness and other characteristics of the chakra stroke attribute, and then try to make the chakra become what it feels like, and then use the chakra to try to cut the leaves to deepen the feeling of change.

The sun and the moon soon caused the chakra to change its yang nature, after all, there was a strong vitality in his chakra. Although the change is not perfect, and it cannot reach the extreme of the change of yang nature, it is just a beginner, but the ability to achieve the change of yang attribute so quickly still surprised Tsunade.

Sun and Moon tried the change of yin nature again, which was much more difficult than the yang attribute, but under Sun and Yue's keen and careful sense, he still quickly found the feeling of agility, radiance, and will in the chakra. The change in Chakra's yin nature was also successful, and Tsunade was a little stunned at this time.

At the same time, the sun and the moon also found that the two attributes of yin and yang are not only one at the same time, but the two are fused with each other, hidden from each other, and replaced by each other. Chakra can produce both yin and yang changes at the same time, but it is too difficult to have both yin and yang changes at the same time, and it is impossible to do it with the current sun and moon.

Sun and Moon guessed that this was the basis of the legendary 'Yin and Yang Escape', the combination of Yin and Yang Escape. But Sun and Moon didn't know that he had the possibility of using Yin and Yang Escape only after he had the reincarnation eye and the immortal body, and ordinary people could not let Chakra have two changes in the nature of Yin and Yang at the same time, which was limited by the blood inheritance snare, and belonged to the 'power that only immortals have'.

Tsunade looked at the chakra with a trace of yang attribute in Sun and Moon's hand and nodded: "It seems that you can already achieve the change in the nature of yin and yang." It's not yet mature, but it's pretty good. In the current situation, you can use the healing technique, but you can only barely do it!To reach a higher level, we need to start the 'Yang Attribute Change Special Training'!"

In the same way that Naruto used to cut leaves to train wind attribute changes, yang attribute changes also need to be cultivated, and Tsunade casually handed Sun Moon a basket of leaves that had turned yellow.

"Master, what is this?" asked Sun Yue, looking at the pile of yellow leaves. He didn't expect to practice Yang Dun, but he actually used leaves, shouldn't he use something like a fish, a guinea pig, or something like that?

"This is the training equipment, and you have to use the yang chakra to act on the blades. Then you have to make the whole yellow leaf green again!" Tsunade said with a smile.

"Ahh

"Where is this Mu Dun? Mu Dun is the combination of water and soil chakra, as the source of life, to control the growth and development of plants, and even use chakra to directly create plants. ”

"Master, what I taught you is to use the yang attribute chakra to stimulate plant cells, so that the chloroplasts in the cells can reproduce a large amount of chlorophyll! Plants have strong vitality, are not easy to die, and have cell walls, which are not easy to be damaged by chakras that you don't control, but they are also not easy to be stimulated by chakras, so there is a certain degree of difficulty. This is specifically for training yang attribute chakra changes!" Tsunade said, touching Sun Moon's head.

"Oh, I see. I thought it was to give the leaves a new lease of life. Then master, how can you train the chakra changes of the yin attribute?" Sun Yue asked curiously.

"Conversely, take a green leaf and turn the leaf yellow. Tsunade said.

"Ahh

"Yes, use the yin attribute chakra to act on the cells on the leaves, cut off the contact between the leaf cells with the outside world, and let the cells carry out the program of falling leaves in autumn, most of the chlorophyll in this plant cell will be gradually decomposed under the action of enzymes and oxygen, and the color of carotenoids and anthocyanins will be displayed, and the leaves will turn yellow. Tsunade said.

"Wow, this trick of deceiving plant cells is a bit like illusion! But plant cells have no intelligence, they are just adapting to the environment, as long as they artificially use chakra to affect the environment, they can affect it. Sun and Moon secretly nodded his head.

So the sun and the moon faced a pile of yellow leaves, and divided into 5 shadow clones.

"So, I'll get started!"
