I'm in Naruto Cultivation

Minato went out and finally suppressed Kushina temporarily, and everyone's attention returned to the thunderstorm symbol.

"Xuan Yue, this thunderstorm talisman is indeed as effective as the detonating talisman, especially in creating traps. However, how difficult is it to make such a talisman? It seems that two kinds of chakra, Yin and Yang, are used?"

Minato asked questions one after another.

Xuan Yue was already prepared and said with a smile: "In terms of difficulty, it is almost the same as the detonating talisman. As for the two chakras of Yin and Yang, the Yin and Yang seal I just developed does require the power of Yin and Yang, but it is used for sealing ninjutsu. But don't need it.

Big Brother Minato, you should still remember that in my theory of the Four Elements of Yin and Yang, any chakra contains the conclusion that the power of Yin and Yang is included.Therefore, as long as you know the sealing technique, it is not difficult to perform this sealing technique which I named 'Pseudo Yin-Yang Seal' to perform sealing ninjutsu! "

"I see!"

Minato smiled and then asked: "Then the Thunderstorm Talisman can be used on a large scale, but do you plan to make it yourself and sell it to the village or other ninjas like the Explosion Talisman?"

Xuanyue shook her head decisively: "Such a thing will spread sooner or later, there is no need to hide it!"

There is no copyright protection in the ninja world. Although the sealing technique of pseudo yin and yang seal is quite sophisticated, it is not difficult to learn. Not to mention Konoha Village, even other ninja villages will piracy sooner or later.

In this case, it is better to use it openly to cooperate with those ninjas. For example, the Sarutobi clan would be happy if they were taught how to make thunderstorm charms and then take a commission from the thunderstorm charms sold.

Of course, the most important thing is that the Uzumaki clan only has him and Kushina in Konoha, and there are only three people in the Kasuimon clan.

"Very wise choice!"

Watergate agreed.Kushina muttered a few words, but in the end did not object.

The matter was settled like this, the three of them went home and had lunch first.In the afternoon, Xuanyue specially made ten thunderstorm talismans and handed them over to Minato, who went to see Hiruzen Sarutobi.However, Kushina was afraid that her husband would suffer, and went to the Hokage office together.

In Shigu Forest, Xuan Yue picked up the compiled experimental data and browsed it quickly, then frowned and said: "In other words, as long as the pineal gland does not become diseased, the state of unity between man and nature can last for up to sixty minutes. , that is, one hour. After more than one hour, the disease will occur. If it exceeds two days, the pineal gland will gradually lose its ability to control emotions, and it will be in a state of harmony between nature and man. However, if it exceeds thirty days, the state of harmony between nature and man will become unstable. State, emotionally out of control!”

"What a disappointing result!"

Xuan Yue couldn't help but sigh.

"Not to mention disappointment, these are all expected!"

Tsunade said calmly, then pointed to the experimental record in Xuan Yue's hand and said: "If the time to enter the state of unity between heaven and man is limited to ten minutes each time, then you can have up to twenty opportunities, twenty Within a few times, the pineal gland will not be affected!"

After hearing this, Xuan Yue immediately turned to the next page. After browsing it, she finally showed a hint of joy: "Twenty times, it is really a blessing among misfortunes!"

"No, twenty times is just an ideal state based on experimental data, but Xuanyue, don't forget, you use the technique of spiritualization to control the clone to enter the state of unity between heaven and man. It also has an impact on the main body, although it is not very obvious. But you have to be careful!"

Tsunade solemnly reminded: "To be on the safe side, you should not use your original body to enter the state of unity between heaven and man more than fifteen times, and each time should not exceed ten minutes. Even if you control the clone body, it is best to enter the state of unity between nature and man every time. It shouldn’t take more than an hour.”

"Teacher, I understand, I will pay attention!"

Xuan Yue nodded honestly.

"It's just that you can't enter the fairy mode by yourself now?"

Tsunade asked again.

"Yes, but the preparation time is too long, the induction of natural energy is too weak, and the efficiency of absorbing natural energy is too low."

Xuan Yue smiled bitterly: "If I don't rely on the state of unity between heaven and man, I can only condense a large amount of magical chakra in advance and store it in a Yin seal. Under such circumstances, the maintenance time will not exceed an hour! Although The original intention of studying Sage Mode was not for fighting, but teacher, you also know that the current situation in the ninja world is becoming increasingly tense, and no one knows when the war will break out.
