A world where [humans, demons and immortals] coexist.
Zhang Quan had an accident when he went to the toilet, and switched bodies with Liu Huaian, who happened to have an accident when he went to the mountain to collect medicine.
In order to snatch the Immortal Bead, the Nether Sect killed one hundred and twenty-four members of the Qingyun Sect. Only the leader, the Great Immortal Qingyun, was seriously injured and fought his way out of the siege. The Nether Sect chased and blocked Qingyun, forcing Qingyun to a cliff. Qingyun jumped off the cliff and was rescued by a roc bird. Later, Qingyun found out that the Immortal Bead in his arms was the result of the emergence of Dapeng's companion. Liu Huaian's father Liu Qiao rescued Qingyun while hunting and took him home for treatment, but unexpectedly the family was destroyed. Liu Huaian became an orphan and depended on Qingyun.
Zhang Quan felt that he was living a useless life in the 21st century, so he practiced painstakingly for ten years using Liu Huaian's body and the immortal beads presented by Qingyun Immortal, just to avenge Liu Huaian's parents and the death of more than a hundred Qingyun disciples, and also to prove that he was not a wimp.
However, the power of the Nether Sect has penetrated the entire world, which means that the revenge of Liu Huaian and Qingyun Immortal will be more difficult. The Nether Sect has turned into a cult and has cultivated many puppets through mind control. Huai'an and Qingyun went straight to Huanglong through the clue of Famen Temple.
In the end, Liu Huaian was surprised to find that the real mastermind behind the Netherworld Sect was actually a woman. This woman also traveled from the 21st century.
