After the sudden death of modern medical doctor Wu Yulan, she transformed into the mean and evil mother-in-law of the Song family. The original person treated his daughter-in-law harshly, sold his granddaughter, and forced his eldest son to have his leg broken, just to pamper his youngest son Song Zhishu. After traveling through time, Wu Yulan awakened her conscience, used her superb medical skills to save her third daughter-in-law who was having difficulty giving birth, and redeemed her sold grandchildren. She led her family to fish and collect herbs, broke the prejudice that "girls cannot study", and sent all her grandchildren to school. During this period, he cured many squire and noble ladies, accumulated wealth and reputation, redeemed his second son from working as a coolie, resolved family conflicts, and repaired the relationship between in-laws and relatives. With her efforts, the Song family has moved from dilapidation and conflict to harmony and prosperity, and the mystery of the jade pendant left behind by her original body remains to be solved.
