The god of death created by the Sealing Technique: Shiki Fuujin, intercepts souls that should have gone to the Pure Land and uses them in the fighting in the ninja world.

Such behavior is, no matter how you look at it, digging into the Pure Land. The Immortal Clan is truly intolerable. This is much worse than exchanging one's own life for another's, or temporarily borrowing one's life for another's in the Impure World Reincarnation.

"So, my conclusion is that Yin-Yang Release is a backup plan left by the Sage of Six Paths. We should always leave a way out. We can't block all possibilities. The creator of the eternal peace and order also understands that a stagnant pool of water will not have any good results. When Kaguya Otsutsuki breaks out of the seal, we need the reincarnation of Ashura and Indra's chakra to use Yin-Yang Release to deal with her."

"In this case, wouldn't it mean that there is no way to master Yin-Yang escape through ordinary methods? Granny Chiyo, who used the reincarnation technique, died directly, and the Uzumaki family, who developed the Demonic Seal, was directly destroyed. Even this opportunistic method doesn't work. What should we do?"

Gongzhi smiled:

"Now that I know the reason, the application is a little simpler than I thought. Back to the original question, in the ninja world, the form of life is too ambiguous, so that the boundary between the body and the soul is not obvious, and chakra can be used to temporarily modify it, or even permanently change it. Haven't we discussed in the past why it is always difficult to accurately guess the state of the Impure World Reincarnation Body? Because there are too many influences, most Impure World Reincarnation Bodies remain the same as they were when they died. At the time of 'physiological death', the characteristics of the body are reflected on the soul through chakra, so Nagato's Impure World Reincarnation Body has the Samsara Eye, and Uchiha Madara's Impure World Reincarnation Body also has the Mangekyō Sharingan and even the Samsara Eye. However, the materials used for Impure World Reincarnation, as well as the strength and ideas of the caster, are also factors that affect the state of the Impure World Reincarnation Body. Think about the pupil technique of Kabuto Yakushi's Mangekyō Sharingan - Sukunami, and you will know that in the ninja world, because of the existence of chakra, 'others are hell' is definitely not just a psychological problem, but a living reality, especially for the vague life form of the Impure World Reincarnation Body, which is more susceptible to external influences."

Putting hope on such an unreliable force is not the right way after all. You never know when you will be retaliated by the Ninja World and the Pure Land.

"Directly manipulating the power of the soul is ultimately only a stopgap measure. Mastering Yin-Yang Escape is the most important thing. So, after studying Chiyo's reincarnation, what did you discover?"

"Yin Yang Escape can be practiced. Although the Samsara Eye is a shortcut to mastering Yin Yang Escape, it is not necessary to have it. We can't expect to have the talent of the Six Paths Sage, but his Yin Yang Escape is not something that can be done easily. We can do it, but it will be a little more troublesome."

As he spoke, Gongzhi took out two scrolls and spread them out. There was a circle of runes drawn on each of them, and a big "fire" character in the middle.

"Fire Sealing Seal? What does this have to do with Yin Yang Escape?"

"There are seven types of Yin-Yang and Five Elements escape techniques. I won't go into detail about the bloodline limits, bloodline elimination, and even bloodline nets that are produced by various combinations. If you want to understand them, it is enough to study these basic escape techniques."

As he spoke, Koji unleashed the two fire-sealing seals, and a ball of pitch-black Amaterasu flame and dark blue soul fire appeared in the basement.

"The flames of Amaterasu and the Two-tailed Matatabi are both Fire Style, but one is the strongest physical attack, and the other is a mysterious fire that burns the soul. Their characteristics are very obvious, one is a Fire Style with the power of Yang Style, and the other is a Fire Style with the power of Yin Style..."

"I know that. I once tried to use Amaterasu and Soul Flame to cast the Thousand Commands, but failed..."

"Try again..."

Koji slowly brought Amaterasu's dark blue soul flame closer together, and then, a little golden spark appeared in the overlapping part of the two, but it disappeared so quickly that it seemed like an illusion.

Although Shuimu was a little confused, he still activated the Sage Mode, and then natural energy slowly enveloped the two flames that were close together.

"No reaction, it's useless... Hey, that's not right!"

In Shuimu's perception, a few sporadic flames suddenly appeared, and then continued to devour the surrounding Amaterasu's flames and soul flames. After a while, under the control of Shuimu's natural energy, the two magical fire escapes were completely devoured.

"Be careful, the seal can't be maintained."

If it weren't for his mastery of sealing, these two indestructible fire balls would have devoured Mizuki's underground laboratory long ago.

Shuimu didn't know how to describe the feeling he had towards this newborn flame. He really couldn't find the right color to describe the shape of this strange, jumping flame.

"This is the Thousand Conquest Order, but... it seems a little different!"

It is so difficult to control, and I even feel vaguely that if I relax, I will lose control.

“Isn’t it amazing?”

Kouji said.

"Granny Chiyo's reincarnation is indeed amazing, because the body and the soul are equally important. In fact, the so-called 'resurrection technique' only needs to call back the vitality of the body and then use a special method to repair the soul mark in the body. The soul of the Pure Land will naturally return. There is no need to go through so much trouble. The Pure Land's restraint on the soul is really pitifully weak."

If it weren't for the constraints of the Six Paths Sage, the ninja world would have become something completely different.

"Granny Chiyo, first use the super-powerful medical ninjutsu to give the body vitality, and then use your own soul as a sacrifice to carve a unique soul mark. Because the soul is unique, the ninja world will place two souls that are recognized as the same individual together, so there is no need to worry too much."

This is just like the computer documents in Shuimu's previous life. The souls of the deceased are archived in a folder called Pure Land. The caster only needs to create a blank soul imprint with the same file name, and the system will automatically merge the two.

"The Pure Land stores the souls of 'physiologically dead' humans, but the Ninja World has lost the ability to distinguish between life and death. Granny Chiyo simply used a trick to deceive the Pure Land, making the Ninja World mistakenly believe that Gaara is still alive. This is the most sophisticated deception in the Ninja World!"

"Is it enough to just combine Yin escape and Yang escape?"

"You think it's not difficult enough?"

"Has no one discovered this method before?"

Gongzhi curled his lips in disdain:

"There are so few Yin-Tun and Yang-Tun techniques, and most of them are still secrets. How can we have the opportunity to study such things? Besides, do you really think there are no wise people in the ninja world?"

Indeed, if Uchiha Madara had not transplanted the cells of the first generation and combined the power of yin and yang, how could he have upgraded the eternal Mangekyō Sharingan to the Rinnegan?
