Upon return to the human world, his parents and sister strangely disappeared, and due to an incident whilst traveling from the fairy world to the human world, he lost his magic weapon and his cultivation became almost zero. Major forces took this opportunity to hunt him down. The fairy emperor became the target of public criticism, and his family was in danger!
