After the Endurance World War II, orochimaru failed to control the pollution and metempsychosis, and Watergate and others soared. Why?

In Naruto, Watergate found the mask of death, released his soul from the belly of death, and was resurrected by orochimaru. One possibility is that orochimaru succeeded from the beginning. Because of the loss of several shuriken and seals, can it really stop the reincarnation of filth? Could it be that Watergate escaped by flying Raytheon after knowing his reincarnation? After all, orochimaru's mastery of filth metempsychosis at that time was still very limited! Another possibility is that the worries of Watergate and others have settled, and the cycle of filth has failed for them.

Inferior soil metempsychosis is an alien psychic forbidden art developed by Muhuoying's second generation. It can summon the souls of people who have passed away back to the world and resurrect them in the form of entities, which was improved by orochimaru and carried forward by Yakushi Kabuto. There are conditions for using inferior soil for metempsychosis, namely: (1) First, a certain number of people's bodies need to be pre-metempsychosis, and those who do not meet this condition cannot be metempsychosis; (2) then the living will be sacrificed as a container for people before reincarnation; (3) The soul of reincarnation must exist in the pure land of bliss. If the soul is sealed, it cannot be summoned. Although performers will be bound to perform, reincarnated people will be liberated by emotional stimulation. From this point of view, Shui Sheng may have finished his thought, and the water gate released by the soul is no longer controlled by the polluted soil and can soar.

According to the story at that time, four generations were not summoned. There are two possible reasons: first, it was stopped by Japan and India, which is what Japan and India said, and there was a printing action; Another reason may be that the soul of Watergate is not in the pure land and cannot be reincarnated. But this guess is not convincing compared with the former. Therefore, the most likely reason is that the liberation of the bound makes the cycle of filth invalid.
