For various reasons, the ninja world is constantly declining, and the upper limit of extraordinary strength is not high, which can be seen from the disadvantages of the Mizuki version of the immortal mode, and the ninja world is indeed suppressing the birth of too strong forces, such as the eye of reincarnation, the eye of reincarnation, and so on.

As the strongest Six Dao Immortals in the ninja world, it is impossible not to be aware of this.

None of the two sons of Otsuki Kaguya inherited the world-destroying level pupil technique of reincarnation writing wheel eyes.

The descendants of the six immortals have not even been able to pass on the reincarnation eye, and no one has been able to inherit the immortal body and the immortal eye completely, and even the reincarnation eye has degenerated into another blood inheritance limit pupil technique that is not bad in combat effectiveness, but has greatly weakened its influence on the ninja world-Writing Wheel Eye.

The secret technique of Kaleidoscope Writing Wheel Eye, whether it is Amaterasu, Tsukiyomi, Kamui, or even Izanagi and Izanami, etc., will not be much worse than the eye of reincarnation, but the most important point is that the authority to control the Ten Tails, that is, the sacred tree, is stripped away;

The eye of reincarnation should not appear again, not only the objective conditions of the ninja world, Mizuki thinks so, the six immortals also made restrictions with practical actions, the difference between chakra yin and yang is proof, for thousands of years, no one has ever been able to gather the power of yin and yang to open the eye of reincarnation, until Madara Uchiha had an accident under the calculation of the black absolute.

Another clue is the Ten Tails, after extracting the Chakra, it is divided into nine tailed beasts with yin and yang, the intentions of the six immortals are undoubtedly good, although the birth is not very glorious, but the essence of the nine tailed beasts is indeed the collective product of human will, and the ten tails once said that they are natural energy, although this is not accurate, but it is not lying.

The contribution of human beings to the energy of nature is manifested in the form of tailed beasts, and the six immortals created the nine tailed beasts, not just to create a super combat power to protect humans through the dangerous barbaric era.

The three psychic beast holy lands have the inheritance of the immortal mode, and they can well screen and use natural energy, but when it comes to the human dominance of the ninja world, there is a big problem.

At the beginning of the birth of mankind, the ninja world was already in extreme decline, and there was still an existence like the Divine Tree, which constantly absorbed the energy of nature.

From the very beginning, humanity has been in a very disadvantageous position, and not only have the unqualified human beings not only been unable to use natural energy, but also have extremely narrow access to their own supernatural powers.

The six immortals are divided into yin and yang, and it can also be said to limit the reincarnation eye, so what is the reason for the birth of the five elements ninjutsu of earth, water, fire, wind, and thunder?

In fact, this answer is not difficult to guess, because this time the spirit of all things has been so weak that most individuals cannot use the power of chakra, and as a last resort, the six immortals will leave behind and pass on the concept of seals, five elements, and ninjutsu, chakra itself does not matter what attributes it is, but humans have to use the secondary power of seals and ninjutsu according to their own qualifications.

You must know that when the Six Dao Immortals and their younger brother Da Barrel Mu Yu Village use chakra, what attribute seal can they use? Freely control all chakra changes, and what affects its form and nature is only their own will, not their physical qualifications.

Humans as a whole are no longer able to control the power of chakra, and they have to inherit the use of chakra in the way of dividing the five elements, so isn't the natural energy, the greatest treasure house for human beings, even more unusable? Coupled with the influence of the Divine Tree, the "bad deeds" that humans have betrayed have basically eliminated the possibility of using the power of the Immortal Mode.

Ignoring the unexpected help of the Holy Land of Psychic Beasts, the purpose of the Six Dao Immortals in creating the Nine Tailed Beasts, through this series of clues, a looming vein surfaced in Mizuki's heart.

The Nine Tailed Beasts are most likely the helpers arranged by the Six Dao Immortals to help humans learn to use natural energy and control similar immortal powers. This is the most likely explanation after Mizuki sorted out the information and speculation at the time.

"There is toad oil in Myoki Mountain, and humans have tailed beasts. Only my immortal mode cultivation method is orthodox, although it is a bit off!"

There is no problem with the methods provided by other intelligent races, just like a small car, with different grades of gasoline, most of them can drive fast and well, but the most suitable is always the best brand when the car is designed, not only easy to use, but also does not hurt the engine. The Nine Tailed Beasts are the bodyguards and nannies customized by the Six Dao Immortals to escort humans, plus the enlightenment and protection medium using the Immortal Mode.

It's just a pity that humanity screwed it all up.

In the Fourth Ninja War, the kind of powerful power shown by Naruto Uzumaki can not only recognize malice towards humans, but also distribute the power of the Nine-Tails to many people to play a protective role, and the combat power of the Nine-Tails is an existence that can directly confront Madara Uchiha, which is a model of joint combat between humans and tailed beasts.

As for Mizuki, it's a pity that the difference in soul makes Mizuki choose a violent and wrong way to use it, and the drawbacks are inevitable.

Therefore, Mizuki wanted to test the ninja ninja natives on how humans and tailed beasts would get along with each other, and how to achieve a stable and safe use of natural energy.

"It's definitely not enough to use the Tailed Beast Chakra as a medium to sense and absorb natural energy, and I've proven it undesirable with my own experience!"

What exactly should it be, Mizuki himself can't try it at all, and he doesn't even have the ability to perceive without using the tailed beast chakra to absorb natural energy. The real predicament made Mizuki quite helpless, so he had to make up his mind with Sakura.

"You're not here just to tease, are you?"

"Of course it's important!" said the clone with a smile, "Exchange memories first, and you'll know." ”

……

A quarter of an hour later, Mizuki himself savored it for a while.

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

"I lost a lot of time on other things, and it was already a lot more difficult to develop attributes that I wasn't very good at. ”

Mizuki 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 too unfamiliar......"
