In the previous life, Jiang Wanyin was paranoid and crazy about Xiao Jingai, the Queen's legitimate son, and was willing to become a knife in the Queen's hand and a chess piece in the Jiang family's pursuit of power. She cleared away all the people and things that hindered Xiao Jing from ascending to the throne. In the second year after she helped Xiao Jing ascend the throne and become queen, Xiao Jing beheaded her in public, and the Jiang family abandoned her and put all the blame on her. At that moment, she realized that for many years, the person Xiao Jing loved had been the daughter of the Shen family she had eradicated, the third young lady of the Shen family. Because of her loss, the Shen family collapsed and Shen Qinghe was killed. Xiao Jing had always hated her and the queen. He pretended to love her, but in fact he hated her and wanted to die the next moment. After her death, she came to the new century and became a Chinese medicine doctor. After an accident, she returned to her previous life when she was fifteen years old. This time she would never pray for that illusory love and become a vicious person. This time, she was just herself. In order to make up for the mistakes of her previous life, she saved the Shen family, cured epidemics, and eradicated corrupt officials. Through this, she got to know Shen Zhiyu, the prime minister. The two conspired many times along the way and had a tacit understanding.
