While people with supernatural powers all over the world are studying how to "scientifically control beasts", a young man from Northeast China who is regarded as mentally ill is being cried by the demons from the Book of Mountains and Seas, begging him to be their ancestor.
This is a modern myth about a descendant of the Northeastern Immortal who adheres to the ancestral motto of "Brother Chu", uses the simplest Jianghu morality and the subversive "group chat" magic to fight against the demon clan's conspiracy, bridge the gap between humans and demons, and is finally respected by all demons as the "ancestor".
