Shen Zhiwei, a top modern medical student, died unexpectedly and traveled to the fictional dynasty "Dayan". She became the eldest daughter of the Zhenbei Hou Mansion who was mistreated by her stepmother and lingered on the sickbed. In order to save herself and get rid of the fate of being used as a pawn by her family and marrying the "Living King of Hell" Seventh Prince Xiao Jue, she relied on the knowledge of modern medicine and pharmacology accumulated in her previous life to regulate her body in a desperate situation and seize every opportunity to show off her talents. She used her medical skills to break the situation, from fighting in the back house to setting foot in the court, curing difficult and complicated diseases, uncovering latent diseases, improving the medicine used in the army, and gradually clearing away the stigma, accumulating reputation and capital. In the process of going from mutual suspicion to fighting side by side with the Seventh Prince Xiao Jue, who is cold on the outside but hot on the inside and carries a heavy past, she not only uncovers the secrets of her life experience and the conspiracy of the Hou Mansion, but also in the treacherous court situation and border crisis, she stabilizes the court and benefits the people with her benevolence and extraordinary wisdom as a doctor, and finally wins freedom, respect and unique love.
