After a cultivator dies, or even before death when the soul departs from the body and occupies another person's shell, this is called soul possession.
But doing so usually causes conflicts between the soul and the body. After all, they are not original, but rather foreign to each other, which generally leads to rejection phenomena, causing both to weaken.
Nevertheless, the cultivation world has developed to an extremely prosperous and thriving state; various cultivation techniques and skills emerge continuously and advance. Therefore, the skill level of soul possession has also become increasingly high and developed.
In comparison, the situation of great power reincarnations is much rarer.
Reincarnation implies being reborn.
Rebirth and possession have differences.
