A descendant of a modern family of traditional Chinese medicine pretends to be the legitimate daughter of a general who was transferred from an imaginary dynasty. She is bound to the "Ji Shi System" but is robbed of her golden finger by a reborn female partner. In order to save herself, she was forced to take the place of her twin sister and enter the palace to treat the tyrant. She used real medical skills to kill the tyrant in the imperial hospital, but found that the strange poison in the tyrant's body was related to her death in the previous life.
