As a living dead, he is the founder of the immortal world, Taoist world and Buddhist world, an immortal existence. He is in charge of the peace between demons, monsters and the human world. His indifferent heart makes him think that this world is extremely boring. He must find an heir, a person with a completely negative destiny. But this person seemed very different. He wanted to continue living, and found him in every life to be by his side.
Until the abyss of the demon world ruptures, there is no choice but to inherit the identity, and he also loses his immortal power, becoming a disembodied ghost that needs spiritual nourishment. It is explained that he has become a ghost and the ghost king of the underworld, and his identity and status remain the same.
Purpose: I will always be on the front line for my homeland.
