Due to various reasons, the level of power in the ninja world is constantly declining, and the upper limit of the supernatural power is not high. This point can be seen from the drawbacks of the immortal mode of the Shuimu version. The ninja world is indeed suppressed. The birth of too powerful forces, such as Samsara, Tensei and so on.

As the most powerful immortal in the ninja world, it is impossible not to notice this.

Neither of Kaguya Otsutsuki's two sons had inherited the world-destroying pupil technique called Samsara.

The descendants of the Six Path Immortals could not even inherit the Eye of Reincarnation. No one can inherit the body of the Immortal and the Eye of Immortal. Even the Eye of Reincarnation has degenerated into a person whose fighting power is not bad, but its influence on the ninja world is greatly weakened. Another kind of blood following the boundary pupil technique - writing round eyes.

The secret art of kaleidoscope writing wheel eye, whether it is Amaterasu, Moon reading, Shenwei, or even forbidden art such as Izanagi and Izanami, is not much worse than Samsara Eye, but the most critical point is to control The ten tails, that is, the power of the divine tree, was stripped away; the power of reincarnation, which can bring people back from the dead, was only slightly comparable to the forbidden art of Izanagi; other manipulations of gravity, spirit, Soul, memory, chakra's ability to escape from yin and yang are all gone.

The eye of reincarnation should not appear again, not only the objective conditions of the ninja world, Shuimu thinks so, the immortals of the Six Paths have also made restrictions with practical actions, the difference between yin and yang of Chakra is the proof. For thousands of years, no one has ever been able to gather yin and yang to escape. Force to open the eye of reincarnation, until Madara Uchiha had an accident under Hei Jue's calculations.

Another clue is the ten tails. After extracting the chakra, it is divided into nine tailed beasts with Yin and Yang escape. The intention of the six-path immortal is undoubtedly good. Although the birth is not very glorious, the essence of the nine tailed beasts is indeed the collection of human will. , Juwei once said that he is the natural energy, although this is not accurate, but it does not lie.

The contribution of human beings to natural energy is manifested in the form of tailed beasts. The immortals of the Six Paths created the nine tailed beasts not only to create a super-powerful combat force to protect mankind through the dangerous and barbaric era.

The three psychic beast holy places have the inheritance of the immortal model. They can filter and utilize natural energy well, but when humans dominate the ninja world, there is a big problem.

At the beginning of the birth of human beings, the ninja world has been extremely declining, and there is still an existence such as the divine tree that continuously absorbs natural energy.

From the very beginning, human beings have been in an extremely unfavorable situation. Humans with poor aptitude are not only unable to use natural energy, but also have extremely narrow ways to master extraordinary power.

The immortals of the Six Paths are divided into Yin and Yang, which can also be said to limit the eye of reincarnation. Then, why was the ninjutsu of the five elements of earth, water, fire, wind, and thunder born?

In fact, the answer is not difficult to guess, because this time, the spirit of all things has become so weak that most individuals cannot use the power of chakra. The concept of jutsu is passed down, Chakra itself does not matter what attributes, but human beings have to use secondary powers such as knot seal and ninjutsu according to their own aptitude.

You must know, when the Six Paths Immortal Otsutsuki Yui and his younger brother Otsutsuki Yumura use chakra and what attribute seals do they use? Freely control all chakra changes, and it is only your own will that affects its form and nature, not any physical aptitude.

Humans as a whole have been unable to control the power of chakra, and have to inherit the use of chakra in a way of separating the five elements. Isn't it even more unusable for natural energy, the biggest treasure trove for human beings? Coupled with the influence of the divine tree, the "bad deeds" that humans once betrayed basically eliminated the possibility of using the power of the immortal mode.

Regardless of the unexpected help like the Holy Land of the Spiritual Beasts, the Six Path Immortals' purpose of creating the Nine Tailed Beasts, through this series of clues, a looming vein surfaced in Shuimu's heart.

The nine tailed beasts are most likely the helpers arranged by the Six Paths Immortals to help humans learn to use natural energy and control the power similar to fairy magic. This is the most likely explanation after Shuimu sorted out the information and guesses.

"There is toad oil in Mt. Miaomu, and humans have tailed beasts. Only the cultivation method of my immortal mode is orthodox, although it is a bit off track! 』

The methods provided by other intelligent races are no problem, just like a small car, with different grades of gasoline, most of them can drive fast and well, but the most suitable one is always the best grade when the car is designed. , not only easy to use, but also does not damage the engine. The nine big-tailed beasts are the bodyguards and nanny customized by the Six Paths Immortals to **** and **** humans, plus the enlightenment and protection medium using the immortal mode.

It's a pity that humans screwed it all up.

In the fourth ninja battle, Naruto Uzumaki showed the kind of powerful power, not only can identify the maliciousness to human beings, but also distribute the power of the nine tails to many people for protection, the fighting power of the nine tails It is an existence that can directly confront Madara Uchiha, and that is a model of joint operations between humans and tailed beasts.

As for Shuimu, unfortunately, the difference in soul made Shuimu choose a violent and wrong way of using it, and the drawbacks are inevitable.

Therefore, Mizuki wanted to test it on the aborigines of the ninja world, what the six-path immortals expected to get along with human beings and tailed beasts, and how to use natural energy stably and safely.

"It's definitely not enough to just use the tailed beast Chakra as a medium for sensing and absorbing natural energy, and I have already proved it by my own experience that it is not desirable! 』

How should it be? Shui Mu can't try it himself. Without using the tailed beast Chakra to absorb natural energy, he doesn't even have the ability to perceive. The plight of reality made Mizuki quite helpless, so he had to make up his mind on Sakura.

"You're not here just to make fun of you, right?"

"Of course there is something important!" The clone said with a smile, "exchange memories first, and you'll know."

…

After a quarter of an hour, Mizuki's body was carefully experienced for a while.

"The third attribute of Chakra, the change in the nature of thunder, has it been completely completed! It's been almost half a year, and it's really slow enough!

"I wasted a lot of time on other things, and it would have been much more difficult to develop attributes that I am not very good at."

Shuimu nodded, in fact, the clone came this time, just to confirm, what to do next!

"Let's develop the wind attribute first, the water attribute is really unfamiliar..."
