Xu Hua, a history major at Qingyun University, is one of the top scholars at the institution. While browsing through the books in the library, she stumbled upon an old and inconspicuous book that caught her attention. As she began to read, she found herself experiencing various flashbacks.

“I will pass on this artifact to protect you and your descendants for time immemorial.”

Throughout the story, Xu Hua starts having vivid dreams of the Xu Dynasty, in which she takes on the role of Wu Jinghua, a girl from a declining noble family. To save her from the enemies of her father, Wu Jinghua is sent to the palace as a maid, where she eventually becomes the personal servant of the Emperor's beloved concubine.

As Xu Hua reads about the neglect and incompetence of the Xu Dynasty's Emperor in the present age, she finds herself dreaming of an Emperor who is kind and benevolent. Confused by this revelation, she frequently visits the library with the help of her friend Fan Li Jun, a history enthusiast, to try and make sense of her dreams.

Believing that her experiences are more than just dreams, Xu Hua becomes determined to uncover the truth.
