Everyone in the world knows that after death, the soul is left behind. If the obsession is too deep, one thought will turn into a demon and bring disaster to the world. Therefore, those who practice immortality say that if they see those who have too deep obsession and are unwilling to leave for a long time, they must first transform. If there is no result, then kill them. When the person dies, he will turn into a soul, and the soul will be destroyed and destroyed.
