When Lin Yue, a modern medical student, was studying ancient medical books from the Tang Dynasty, the ancient books accidentally triggered time and space fluctuations. Carrying a handwritten note on the integration of modern Chinese and Western medicine, she traveled to the suburbs of Chang'an during the reign of Emperor Gaozong of the Tang Dynasty. When she woke up, she was in a ruined temple and her identity was "Lin Yue, an orphan girl whose family had fallen into disgrace." By chance, they meet Prince Li Hong, who is on tour in disguise, or Shen Yan, the fictional son of an aristocratic family. The other person becomes suddenly ill due to a subordinate's sudden illness, and the relationship develops due to the illness. The progressive emotional development of "curiosity-testing-trust-deep love" emphasizes the mutual understanding between the male and female protagonists on the spiritual level. Li Hong accepts her "identity from another world", and Lin Yue understands his story of "royal helplessness".
