"This world is composed of three independent but interdependent realms: heaven, yin, and yang. The two realms of heaven and yang are separated by the Milky Way, and the two realms of yin and yang are connected by the Qianmo Road and the water of the Styx. The three realms intersect with each other to form the system of reincarnation.
"To put it simply, all living beings exist in this world cyclically in six forms: gods, immortals, humans, demons, ghosts, and souls, and they will never be destroyed.
"This is called 'reincarnation'."
