Lin Xiaocha, a modern social animal, accidentally traveled to the fictional dynasty "Daxia Dynasty" and became the lowest-ranking maid in the palace. This world seems ancient, but it reveals absurd and nonsensical settings everywhere - the emperor is addicted to fighting landlords, the prime minister loves to read cool articles on the Internet, and the largest restaurant in the capital, "Zui Xian Lou", is actually a milk tea shop opened by time travellers. The heroine is a modern 996 social animal, and her major is "useless learning" (that is, learning a little bit of everything but not being proficient in it). A coward on the outside but a bitch on the inside, he is extremely adaptable and good at talking nonsense. It can turn any serious situation into a comedy scene, and inexplicably attract all kinds of weird characters.
