Five years ago, Lin Beifan, a descendant of the Medical Immortal Valley, entered the world and happened to encounter Zhou Wen who was bullied by bad people. After rescuing her, Zhou Wen used her to express her longing for Ye Yunhao, and thus used Lin Beifan as a substitute for Ye Yunhao to get married. Coincidentally, Mr. Wu, the richest man in Jiangcheng, fell seriously ill. Lin Beifan secretly hid the prescription of the Medicine Immortal Valley in Zhou Wen's house and lured Zhou Wen to find it and go to treat Mr. Wu's serious illness. As a result, Zhou Wen made a mistake in taking the medicine, which worsened Wu Lao's condition and put him in danger. At a critical moment, Lin Fan intervened to save Wu Lao's life. Afterwards, the Wu family spared no effort to support their ex-wife Zhou Wen. In addition, the three families of Liu, Zhao, and Qian, who were also among the four major families in Jiangcheng, also cooperated with the Zhou family due to Lin Beifan's influence, making the Zhou family a second rate family in Jiangcheng
