Immortals and demons have different paths, and they should travel the world with you. The Book of Hidden Demons written by Bei Mingyou contains many demons he created sealed. People in the six realms are afraid of it, but want to steal it. But this great creator who existed when the world first opened was actually a very sloppy person. Everyone thought that he realized that the power was too powerful and was afraid that future generations would covet it and steal it, so he created a container to seal the Book of Hidden Demons. But little did he know the truth was: one day he picked up the soul of a starved man on the roadside and felt pity for it, so he wanted to write it into a book. However, who knew that the starving man was always greedy and actually ate the book of hidden demons. Later, due to his carelessness, the book of hidden demons was left behind by him. Eventually, the soul absorbed the essence of heaven and earth and transformed into a female doll. The noble Immortal of the Immortal Realm could not sit idly by and handed the girl over to the Demon King of the Demon Realm. However, because of this decision, the Tiger Clan of the Demon Realm was annihilated. ..."This soul-gathering bead... Contains the souls of all members of the Tiger clan, but not yours."
