From a fantasy point of view, this is the story of two people who made rude remarks on a rainy day and were punished by the Thunder God and the Lightning Mother. From a classical point of view, this is the struggle history of two girls traveling through unknown dynasties and generations on a rainy day. From a serious point of view, this is an inspirational record of two college students fighting against feudal ideas; well... In short, it is a story about two funny men with the same odor who were hacked back to a certain dynasty by the somewhat boring Thunder God and Lightning Mother, starting from "people" and accidentally entering the palace. Imaginary, time-traveling, funny, and occasionally serious.
