The talented girl Xu Yaocai is extremely smart and outstanding. Unexpectedly, one day when she is surrounded by stars, she suddenly encounters a strange incident where her sister is unconscious. In order to find out the truth, she traveled to the Five Dynasties and Ten Kingdoms through the Archmage's travels and became a "memorial girl". Unwilling to be a sacrificial victim, Yaocai was rescued by a handsome young man in white when she was running away from her pursuers. However, she was kidnapped by the cold and domineering third prince Li Zhen and became his concubine by mistake. In order to save her sister and help Li Zhen usurp the throne to become king, Yaocai had to stay with Li Zhen to assist him in exchange for completing the historical deed and making promises. The troubles made by the concubines in the palace and the catastrophe of the westward expedition made Yaocai get to know the seemingly demonic Li Zhen again. The relationship between the two also emerged and stabilized amidst the swaying winds and rains... Gu Yan, the young man in white who had repeatedly rescued Yaocai, also had a deep love for Yaocai. However, what Yaocai didn't expect even more was that the sister she had been searching for so hard was actually the sinister and vicious queen who had been plotting against them behind their backs...
