Gu Yebai was once the "Night King" who stood at the top of the world. After getting tired of the eternal loneliness and strife, he sealed almost all of his power and memory and chose to run a second-hand bookstore called "Wuyouzhai" in a mortal world. He just wanted to be an ordinary single dad.
His daughter An An is a cute four-year-old girl who is full of curiosity about the world. But Gu Yebai gradually realized that his desire to live a stable life seemed a bit extravagant.
Because An An has a pair of eyes that can see "reality".
When An An pointed at the kind old man on the street corner, he whispered: "Dad, that grandpa has a lot of black noodles on his head, and it's moving."
——Those are the descendants of the old rulers lurking in the human world.
When An An held the newly bought doll, she asked in confusion: "Dad, why does this doll always like to dance on the ceiling by itself at night?"
——That is a supernatural thing that harbors hundreds of years of resentment.
When An An watched the weather forecast on TV, she said innocently: "Dad, behind the big sister who reported the weather, there was a faceless aunt standing behind her, smiling at us all the time."
——It is an invisible ghost that heralds disaster.
An An's childlike words became Gu Yebai's most accurate "system prompt".
In order to let his daughter have an undisturbed and sunny childhood, and to protect the only treasure in his life, this man who once made all the gods and demons tremble had to return to his old career.
