I'm in Naruto Cultivation

It doesn't seem to matter much!

But Xuanyue vaguely remembered that in her previous life, the word chakra came from Indian Sanskrit, and the practice of ninja also came from Indian yoga.

And he happened to know the theory of three pulses and seven chakras in Indian yoga. Of course, he was also involved in the study of traditional Chinese medicine in his previous life, and his knowledge was very limited.

But by coincidence, the brow chakra in the seven-chakra energy field happens to be the same location where the Yin seal stores chakra.

So this is why Xuan Yue wants to get the Yin Seal, and wants to know whether this technique is related to the seven-wheel theory that she knew in her previous life.

"The Yin seal fine-tunes the chakra of the whole body, which can be used to seal up the extra chakra, and another effect it brings is to maintain youth."

"However, does this effect come from the Yin Sealing technique itself, or is it because the position of the chakra it seals is just in the human energy field of the eyebrow chakra?"

"Furthermore, as for the Yin seal, can chakra only be sealed between the eyebrows?"

"Is it true that it is for beauty?"

Xuan Yue frowned, dissatisfied with Tsunade's answer.

"This teacher is so irresponsible..."

Xuanyue secretly complained, but she forgot that Tsunade was not willing to be a teacher at all.

"The specific situation cannot be determined by just looking at the principles. You can only feel it by practicing it yourself!"

"It's just, is it really good to seal Chakra between the eyebrows, I'm a man..."

Xuanyue's face suddenly twitched, and she thought about it: "It seems that you have to plan to cooperate with Orochimaru. If you want to explore the seven-round energy field, you must use a clone, and shadow clones are useless!"

He doesn't know much about cloning, but fortunately there is an Orochimaru.However, this guy is also a dangerous person.

"However, the most important thing right now is the Yin seal and the Yin Escape Chakra!"

Concentrating on her emotions, Xuan Yue began to study the Yin seal attentively.

The next day, Xuan Yue still separated a shadow clone and went to school, while the main body stayed at home to study the Yin seal. After last night's research, he already had an in-depth understanding of the Yin Seal. For him, the biggest difficulty of this technique is not elsewhere, but in the chakra control that he is already good at.

There is no doubt that this technique is a sealing technique, and the Uzumaki clan started from the sealing technique, and they are extremely talented. Xuan Yue has already learned the sealing technique with Kushina, so this aspect is not difficult, and this technique has great influence on chakra. The control requirements have reached the heaven-defying level.

All he can say is that it is indeed the first ninjutsu of those two forbidden arts!

Another important point is that the acupoints and meridians used in the Yin Seal are connected to the pituitary gland.

Xuan Yue finally understood why Tsunade became so fierce. Of course, this is not the point. The point is that the secret of Tsunade's youthfulness and beauty comes from this.

"Learn the Yin Seal, and if you give me time, I should be able to create the two forbidden techniques of Creation and Regeneration and the Technique of Hundred Heroes without Tsunade's teaching. Of course, this will take a long time..."

This is not because Xuan Yue is boastful and arrogant, but because he has an amazing understanding of the human body.Judging from the effect of creating regeneration and the technique of Baihao in the original work, the key lies in the pituitary gland, which is closely related to the Yin seal.

why?Because the pituitary gland can secrete seven very important hormones.

First of all, growth hormone can promote growth and development, protein synthesis, and bone growth.Secondly, prolactin, this needs no explanation...

The focus is on thyroid-stimulating hormone, which stimulates thyroid hyperplasia, cell enlargement, and increase in number.

All in all, the pituitary gland is the master switch that regulates the health and balance of the body, controlling the secretion of various hormones that are important for metabolism, growth, development, and reproduction.

After the average person is 40 years old, the pituitary gland shrinks, and the human body will begin to age rapidly.

Obviously, the Yin Seal has a huge role in maintaining and nourishing the pituitary gland with chakra, so much so that in the original work, Tsunade is still like a young woman when she is , or years old.

"It's a pity I don't have a blank eye..."

Looking at the human anatomy diagram on the scroll, Xuan Yue couldn't help but sigh, but his eyes were not on the pituitary gland, but on another location.

Pineal gland!
