Meng Lingge, the legitimate daughter of the Prime Minister, was reborn on her wedding day, and discovered that her fiancé was having an affair with his concubine. The other party actually forced her to serve the same husband. She broke off the engagement in public but no one dared to accept her. At the critical moment, the "idiotic" prince Wen Zhimo from her previous marriage stepped forward to marry her. After the marriage, Meng Lingge borrowed the help of a friend who was a miracle doctor in his previous life and found out that Wen Zhimo was bewitched by his concubine and the queen and was not really stupid. She resolved many frame-ups, joined forces with Wen Zhimo to fight the epidemic, exposed Guan Yi's conspiracy to hoard medicine and harmed the people, and avenged the blood revenge of her previous life. In the end, she helped Wen Zhimo remove the poison, and worked together to overthrow the rebellious concubine, the queen, and others. The enemies were brought to justice, and the two gave birth to children and spent the rest of their lives together.
