In order to avoid being "hunted" by his ex-girlfriends, Lu Ze broke into an ancient temple deep in the mountains in a panic. He accidentally discovered an ancient painting with a koi carp, and sprinkled water on the painting, breaking the seal. The koi carp turned into a human being, but she was a little girl who didn't know any magic except longevity! How should he get rid of this sticky plaster? After rejoicing, the human and the demon take different paths, where should they go?
