World view: Souls can be exchanged. If a person dies, they can be borrowed to live in someone else's body (the prerequisite for exchange and borrowing is the consent of the parties involved. If the exchange or borrowing is forcibly carried out, the body will explode and die; after three years of exchange or borrowing, both parties will die, and the other soul will perish if it takes more than a day to come out. If you want another soul to live in another body, the soul of the original body must agree and the body will soon perish, but after the soul is exchanged, the body will recover, and the soul of the original owner of the body will perish immediately when it comes out)
Purpose: Equality
