Although the two are very similar in origin, their development paths are very different.

Orochimaru values ​​the combat capability and life-saving function of the Eight-Headed Technique more, while Mizuki cares more about the spiritual connection attribute of the Okisou. This is the fundamental reason why the two ultimately go in different directions.

"Come to think of it, the original intention of our developing Xishuixiang has almost been forgotten!"

Shuimu hesitated for a while and said uncertainly.

"The overly violent and unrestricted Sage Mode caused my spirit to be severely eroded by natural energy! But it is indeed surprising to see it reach this point..."

As a trump card for turning the tables after defeat, it was only put on the agenda later.

Mizuki, who rejects the idea of ​​becoming a non-human being from the bottom of his heart, actually doesn't like becoming like Orochimaru, lost in the unrestrained expansion of self-cognition. What he fears most is turning himself into a "god" or "devil" with no humanity left.

This irreversible mental change is more difficult for Shuimu to accept than the physical transformation.

The latter can be solved as long as Shuimu uses biotechnology to create a suitable body and then uses reincarnation or some other reincarnation technique. However, the permanent mental change is irreversible.

In fact, it is said that it cannot be reversed. Shuimu cannot even guarantee that when he notices the changes, he can still stick to his original ideas. This is the most frightening thing.

Shuimu absolutely could not accept that his inner intentions were silently reversed, and that the changes were caused by external interference.

Use Xishuixiang as an intermediary to connect all physical clones and other sub-personalities captured by illusions, so that the original Shuimu has enough buffer to resist interference with itself.

The incarnation of obsession condensed by Xishuixiang is undoubtedly a part of Shuimu's original spirit, and it can be controlled freely without any abnormalities.

This not only provides sufficient defense for the main body, but also is the embodiment of mental obsession that combines offense and defense, and is also the last barrier that isolates Mizuki from the erosion of the ninja world.

"Now, is my true body not affected by natural energy?"

The Xishui Township that suffered the damage has not shown any abnormalities and is still growing steadily. There should be no problem. However, Shuimu always feels that some details seem to have been overlooked!

Gongzhi followed the proper procedure, checking Xi's sleeping state, and then explained:

"There are actually two isolation shields between the main body and the outside world. Logically, natural energy will no longer directly corrode you, but will first react on the obsession incarnation. However, the obsession incarnation is supported by us. If something goes wrong, then our physical clones must have lost themselves. In other words, you don't have to worry about your mental state before we show any abnormalities."

Mizuki nodded.

"I know that I designed this mental defense system, but it's better to be safe than sorry!"

The illusory spiritual level, once there is a lack of consideration, it will be a big problem that is difficult to make up for. Orochimaru was disturbed for decades because of a careless move, and he had to wait for the right moment to escape from danger.

If there is a problem with Shuimu itself, there will not be decades for Shuimu to slowly adjust.

Hope fiddled with the unconscious Kakuzu on the ground as if it had nothing to do with her, and said lazily:

"Let's put these troubles aside until you get through the disaster of the Ten-Tails' resurrection!"

"That's true!"

If Kaguya Otsutsuki is dealt with, Mizuki will have enough time to think slowly. If he fails, the ninja world will probably be destroyed, and Mizuki will also be dead, and all worries will be useless.

Since Orochimaru was able to abandon the past and start over without hesitation, if there were major and irreparable problems in Xishui Township, it would not be unacceptable to simply abandon it.

The only trouble is that all the physical clones may be implicated and mental shock is inevitable. As for escaping from Shuimu's control, there is nothing that can be done about it. Although there are some backup plans in the curse imposed on the physical clones, only God knows whether they will be of any use in front of the physical clones that have inherited Shuimu's knowledge.

At that time, for these physical clones who had always lived in the shadow of water and wood, the sea was truly wide for fish to leap and the sky was high for birds to fly.

If that time really comes, it can only be considered bad luck for the ninja world, and we can only wish for the best.

Just as Shuimu was thinking, there was finally movement in the corner of the ground.

It seemed that the guy who had just awakened was still a little uncomfortable. After standing up, he moved his head and wrists before stopping.

"How do you feel?"

Mizuki asked with interest.

"As you expected, the spirit in this body is actually a mess. This guy doesn't remember things that happened decades ago very clearly. The memories that his soul can hold are only between 20 and 30 years. His impression of the assassination of the first Hokage, Senju Hashirama, is already very vague. He only roughly remembers that this happened, but the details are completely gone."

If this continues, the breadth of Kakuzu's soul will surely decrease again, and he will gradually become an increasingly forgetful, demented ninja, and even forget how to perform ninjutsu and how to use the Earth's Grudge, and then of course he will die of old age and lose his body functions.

"This is really surprising. The three famous immortals in the ninja world, Hidan, Orochimaru and Kakuzu, have become lunatics, paranoids and dementia patients. As expected, for short-lived species, it is difficult to get through the first hurdle if they want to live forever."

Mizuki Shin doesn't think highly of this kind of longevity technique. He thinks the method of a wise man like Orochimaru is more reliable, although it's too disgusting.

"You should still use Kakuzu's name. After leaving the Land of Rain, just continue to symbolically search for Konan, and then wait for Uchiha Obito to summon you to participate in the Fourth Shinobi World War."

"I see. Without further ado, I'll leave first."

Kakuzu's own condition also needs to be adjusted. If he stays here for too long, he might be discovered by White Zetsu, who has super reconnaissance capabilities.

After the perfect spy sent by Shuimu left, Shuimu once again focused his attention on Xishuixiang.

This illusion space with its own spatial properties has the incarnation of Mizuki's obsession. Although there are many devout believers who provide power all the time, making it stronger and stronger, but at this speed, it is still difficult to say how much effect it can play when dealing with Uchiha Madara and Otsutsuki Kaguya, who are the Ten-Tails Jinchūriki.
