Reincarnation is not rebirth. Chaos ends because of you and opens up because of you. The soul protects the final pure land. No matter it is the pure time of the God Realm, or the ghost world of the Demon Realm, or the pleading of the loved ones in the mortal world, they cannot stop them from being completely sealed, allowing you to spend this long life with your child.
Purpose: To seek peace for the world
