Living Corpse Reincarnation

he Living Corpse Reincarnation is a technique that was developed by Orochimaru that allows him to transfer his soul to someone else's body. If periodically repeated, it grants the user immortality as long as they can find new host bodies and keep them alive. Orochimaru can only perform this technique once every three years. It also seems that when the three years are almost over, he is forced to move into another host, as the previous one begins to weaken and reject him.
