The title of immortal is not just talk.

From using chakra refined by oneself to using natural energy, it is the sublimation of ninja from the inside out, and Senjutsu Chakra is the most concentrated manifestation of this change.

The ability to use tools and use them to make more complex tools is the dividing line between wisdom and barbarism; specifically in the ninja world, it is the boundary between intelligent creatures and beasts.

Ninjas changed from only being able to exploit their own strength to becoming immortals who borrowed natural energy. The increase in combat power was only one aspect; the key was a qualitative leap in life form.

Of course, the immortals here are different from the immortals that Shuimu originally understood to be like gods.

The Sage Mode focuses more on application and does not attempt to take natural energy for itself. It only passively changes imperceptibly in the process of using the Sage Mode.

After all, chakra is not an energy for cultivating immortals like the vital energy of heaven and earth, which can make one not need to eat or drink after being absorbed into the body, can live as long as heaven and earth, and dare to compete with the sun and the moon.

Although the principles of the two types of immortals are somewhat similar, they are very different in nature, and the difference in skills and ways is still very obvious.

In comparison, the Jinchūriki, especially the Ten-Tails Jinchūriki, actually goes one step further than the Sage Mode. It is a new form of life that combines one's own life with the representative of natural energy, the tailed beasts. In form, it is actually closer to the end of the power of the ninja world. Uzumaki Naruto's Nine-Tails Mode is a good example of this, but this quick-success method has too many hidden dangers and relies too much on the tailed beasts, making it far less convenient and free than the Sage Mode.

Sakura frowned and thought for a while, then shook her head helplessly:

"I roughly understand what Master said. Sage Mode is very powerful, but why are there so few people practicing it?"

"Not everyone is qualified to practice Sage Mode!"

Mizuki paused.

"Let's put it this way. Think of the ubiquitous natural energy as the ocean. The ninja is the fisherman who wants to go out to sea to fish. The chakra is the fishing boat that carries the fisherman through the wind and waves. The ninja's perception ability is the fishing net. If you want to catch the big fish in the ocean, both the fishing boat and the fishing net are indispensable!"

"Without good perception, even the most powerful ninjas can't catch fish. This is the dilemma of most ninjas. Limited by their innate talents, it is very difficult to improve! You are different. You can now feel the existence of natural energy, but you also have a problem that many masters who aspire to the Sage Mode cannot avoid - insufficient chakra. This is like a fishing boat that is not big enough or strong enough. The sea is not calm. A huge wave comes and the tragedy of the boat being destroyed and people dying is also common!"

Theoretically speaking, a large amount of chakra is not a necessary condition for practicing the Sage Mode. A truly talented person can develop the ability to turn rivers and seas upside down with bare hands. A fisherman paddling a canoe may not necessarily be unable to catch fish, and a captain driving an armored battleship is not infallible.

It’s just that the two have completely different abilities to resist risks. A bigger ship has a much stronger ability to resist risks. Even if it encounters difficulties for a while, it can return safely and have a chance to start over. A small boat can only sink to the bottom of the sea to feed the fish.

"Then I can't practice it? No, I can..."

Sakura suddenly came to her senses. The Breath-Concealing Technique, which had been working silently and had basically concealed Sakura's chakra weakness, finally revealed its true purpose. It is like the air that is needed for life at all times. Everyone knows that they cannot live without it, but they always intentionally or unintentionally ignore its important role.

"It's good that you understand! Chakra gives ninjas the foundation to use extraordinary powers. As long as you control the quality and quantity of chakra, it is equivalent to mastering the source of ninjutsu. Many things that are impossible for other ninjas are not a problem for you!"

Sakura finally understood what the high-level ninjas were thinking about. One or two high-level ninjutsu? How to defeat a strong enemy? Or come up with some unsolvable tactics?

This is something that only young ninjas would care about. When one's strength reaches a certain level, trivial matters will not play a decisive role. The cornerstone that supports one to make further progress is the understanding of the ninja profession and one's own choice.

"You want to practice Sage Mode, so I will teach you. But you must be aware of the dangers involved. Natural energy is very dangerous. Before I allow you, you must not take the initiative to absorb natural energy into your body. Otherwise, if something goes wrong, I may not be able to save you!"

The Eight-Headed Technique is a good way to compensate for mental damage, but it is wishful thinking to expect a little girl of fourteen or fifteen years old to have some understanding of the soul and spirit.

This is a spiritual practice that requires sufficient experience and understanding of life to find one's own path. If you talk about the philosophy of life to a little girl who is still obsessed with premature love, it would be like playing the lute to a cow.

After explaining the training plan for the next period of time, Mizuki sent Sakura back. For the training of Sage Mode, Mizuki only taught her how to sense natural energy. He didn't even tell Sakura how to synthesize Sage Chakra according to a certain proportion, for fear that she would not be able to control herself and accidentally make the wrong choice.

Practicing the control of the tailed beast's chakra and training the perception of natural energy are two-pronged approaches that should be able to promote each other. When the time is right, you can practice the Sage Mode in one fell swoop. This is the safe way.

…

As the leader of Konoha Village, Tsunade rarely pays special attention to any particular ninja.

Shuimu, who never makes big mistakes but keeps making small ones, often brings some small troubles, but most of these troubles are not caused by him. Shuimu just exposes these things hidden in the dark one by one.

Therefore, even if she was dissatisfied with him, as the Hokage, she could not do anything to Mizuki. Dealing with it impartially was her only option.

The feeling of powerlessness and inability to control one's own affairs made Tsunade, who had been the Hokage for more than two years, exhausted, especially when there was an old guy who was eyeing the position of Hokage and embarrassed her from time to time!

But recently, those guys finally did something gratifying.

"Mizuki, are you going to teach Sage Mode to Sakura?"

"Yes! I wonder what advice Lady Tsunade has for you?"

"Nothing, be safe!"

Shuimu's forehead suddenly went dark. Why did these words sound so awkward?

Looking at Tsunade's teachable expression, Mizuki curled his lips.

I guess some people have been looking forward to Mizuki passing on the Sage Mode for a long time.

Any method of practicing the Sage Mode is extremely precious. If no one can inherit it, the village will suffer a great loss.
