I'm in Naruto Cultivation

After struggling to pick up the dead Tsunade home, Xuan Yue couldn't help but sigh a little as she looked at Tsunade who was drooling and talking in her sleep: "This is also a poor person!"

Shaking her head, Xuan Yue made the floor on the side, then continued to familiarize herself with the water escape chakra, and didn't rest until midnight. The next day he still got up early to exercise and practice forming seals.

Three poles in the sun, Tsunade held a piece of bread and leaned lazily at the door, looking at Xuanyue standing in the courtyard with her hands folded.

After staring for a moment, Tsunade couldn't help shouting, "Hey, kid, what are you doing?"

Xuan Yue was awakened, opened her eyes and turned around: "Lord Tsunade, I'm not called a kid, I'm Vortex Xuanyue!"

"As for this... of course I am practicing chakra!"

"Well, I get it..."

Tsunade waved her hand and then stepped forward: "Idiot, what a mess. Refining chakra indiscriminately will damage cells!"

Indeed, the chakra in Xuanyue's body was extremely disordered before, and if it goes on for a long time, it will inevitably hurt herself.

"This situation shouldn't last long."

Xuanyue also felt this point, but it shouldn't be a problem in a short period of time. As long as you succeed once and find out the rules, it will be much easier in the future.

Tsunade frowned slightly and was very curious: "What kind of training are you doing? Kushina taught you?"

"I am practicing to change the nature of wind chakra. Sister Kushina has not started to teach this knowledge yet. It is my own ideas!"

Xuan Yue explained.

"Idiot, how can the change in the nature of chakra be so messy!"

Tsunade drank it coldly. First of all, he has a good relationship with Kushina, and the Uzumaki family and the Qianshou family are even more distant relatives.Furthermore, I have a very good impression of Xuan Yue, and I don't want to see a child go astray.

Feeling Tsunade's concern for her, Xuan Yue couldn't help smiling, explained patiently, and brought out her own theory.

Concepts such as the Four Elements and the Five Elements also exist in Hokage, such as the Seal of the Five Elements and the Seal of the Four Elements, which all involve the theory of the Five Elements and the Four Elements.Tsunade is also proficient in sealing techniques, and naturally has a good understanding of these, but it is clear that the theory proposed by Xuanyue is very different from what she knows.

"The ratio of spiritual energy to physical energy, the rise and fall of yin and yang..."

Tsunade touched her chin and fell into contemplation. Judging from her practice experience, although the theory proposed by Xuanyue is a bit whimsical, it seems to be feasible.

"What a genius kid..."

Looking up at Xuanyue in front of him, Tsunade said, "Mental energy is illusory, how do you quantify it?"

"As expected of Tsunade-sama, one of the three ninjas, in one sentence!"

Xuan Yue helplessly spread her hands and said with a wry smile: "Based on my understanding of spiritual energy, it is currently impossible to quantify it. I can only rely on feeling!"

"Feel?"

Tsunade frowned, feeling that sometimes it was accurate, but sometimes it was not at all. It was like gambling by himself, every time he felt he could win, but every time he lost.

Xuan Yue obviously didn't think so, and explained carefully: "Because it is difficult to quantify mental energy, I found a reference."

"Reference?"

Tsunade responded quickly: "Water escape?"

"correct!"

Xuanyue gave a thumbs up: "Shui Dun corresponds to the Taiyin among the four elements, and the evolution from Taiyin to Shaoyang is the attenuation of Yin, which is the attenuation of spiritual energy. Well, although it is difficult, it requires countless trial and error. But as long as I do this step, then the following Fire Dun, Thunder Dun, and Earth Dun can be completed easily!"

"As for Yang Dun and Yin Dun, it's a bit troublesome!"

Xuan Yue frowned.

Tsunade was interested and said with a smile: "Well, if you can do it, I can teach you the use of Yang Dun!"

As an outstanding medical ninja, Tsunade naturally grasped the use of Yang Dun easily.

"Medical Ninjutsu, this is really a surprise!"

Xuan Yue was overjoyed: "Then, that's it!"

After saying that Xuan Yue continued to practice, Tsunade looked at his
