Immortal mode is a state that can use immortal chakra, which is several times or even dozens of times more powerful than in the ordinary state, and can make itself have super perception ability, ninjutsu, body art and illusion will greatly increase the power. After entering the immortal mode, the body will become immortal, and it will change differently depending on the nature of the natural energy absorbed. Based on the face of the Immortal, it is possible to determine the degree of perfection of the user's Immortal Mode, that is, the degree of control over natural energy.

The ninjutsu of a person himself is activated by activating the chakra in the body, and the ordinary chakra is obtained by mixing his own physical energy and spiritual energy, and the immortal chakra is formed after absorbing natural energy (most likely the world's origin power) and perfectly fusing on this basis.

However, in order to maintain the balance of the three chakras (ninja, body, and immortal), each must be maintained at one-third, that is, 33.333......%, once it exceeds or is too low, it will be swallowed by the natural energy in the body because of the conflict between its own chakra and the immortal chakra, and because of the disappearance of the chakra, it will become a stone statue, even if it is lucky not to become a stone statue, there is a high probability of becoming a waste person (more garbage than the five scum of the battle).

Tsunade worriedly tried to persuade Yasuo to give up the practice of immortal arts.

"Yasuo, don't learn the immortal mode, you're already strong now. Originally, I could have practiced, but the difficulty was so good that I almost died at the most dangerous time. ”

Yasuo shook his head: "I don't want to either, but I always have a feeling that something big will happen in the ninja world in the future, and if I can't continue to get stronger, I'm afraid I'll lose my beloved and friends!" ”

"You don't understand! As one of the three blessed lands, the Wet Bone Forest has not succeeded in learning the immortal mode for many years, if you really want to learn, it is better to go to other blessed lands, at least they have successful examples in recent years......" Tsunade's emotions were a little excited, she didn't want Yasuo to take risks with such a low success rate.

The little slug looked at the two people who disagreed, and neither of them could convince anyone, and made a suggestion.

"Two adults, let me make a suggestion next!"

Yasuo and Tsunade were attracted by its words, and since they disagreed, let's listen to it.

"That's right, it's true that no one in the Wet Bone Forest has been able to learn immortal art for many years, and the reason is that the Wet Bone Forest has a lot of differences from the immortal patterns of other blessed lands. For example, the unique toad oil of Myoki Mountain can help practitioners automatically perceive natural energy, which increases the chances of success. Similarly, the Dragon Cave also has a special method to increase the chance (the black cat guesses that there is a special white snake that swallows the cultivator in the stomach or wraps around the whole body, which can not only absorb the power of nature for him, but also rescue him in times of crisis). You can also share your own opinions. Only the Wet Bone Forest doesn't have that kind of thing, everything has to be explored by the cultivators themselves, but they can also provide assistance in times of crisis, but the speed of turning into stone is often very fast, so if it is not pulled back in time, it is still irretrievable. ”

The little slug paused for the two of them to digest it well, and then continued: "My suggestion is that it is better to learn to control the power of the tailed beast first, and when the adult can perfectly maintain the three chakras (1/3 of the ninja tail), then practice the immortal mode, so that the difficulty of each of the four powers will naturally be reduced by 25%. ”

Tsunade reluctantly agreed, but kept muttering: It's going to be a waste of our time again, and I still want to get married sooner......

The war in the Land of the Wind is not over yet, and Tsunade has been delayed for several days, which is a dereliction of duty as a front-line commander, so he went back without continuing to accompany Yasuo.

After a day of adjusting to the best condition, Yasuo began to control the tailed beast.

"Drink!" Opening the seal on his body, a stream of pure tailed beast chakra poured out of his body. Due to the isolation of the Wet Bone Forest, the Morizuru's deity was unable to influence it.

The control of the tailed beast was successfully completed, and at this time, the cyan tailed beast coat began to appear.

Wanting to test its strength, Yasuo pulled out the knife in his hand, and naturally, the cyan chakra covered the knife in full.

After warming up as usual, Yasuo felt that his various attributes had increased by about 20%. Don't underestimate this 20%, the stronger the person, the more difficult it is to increase, let alone 20% of all attributes! This is not a simple 1+1, and the boost it will bring will be huge.

"Now try the Half-Tailed Beast!"
