Mortal World and Immortality

The vast universe is vast and consists of countless big worlds, small worlds, and secret spaces. The universe is divided into three levels: the lower realm is the mortal realm, which is the starting point for cultivators; the middle realm is the spiritual realm, which is the destination of those who ascend; and the upper realm is the divine realm, which is the realm of heaven. Above the Three Realms, it is said that there is a 'Dao Realm' beyond the God Realm, but no one has confirmed it.
