Modern doctor Wu Yulan's soul has passed through the ancient evil mother-in-law and is bound to the medical mall system. She changed from her usual meanness and used her medical skills to save her daughter-in-law and granddaughter from childbirth, thus breaking her bad reputation. After that, she redeemed her granddaughter who was sold, cured her eldest son's leg disease, recalled her second son, and reunited the whole family. Wu Yulan also started practicing medicine and improved her family situation. The younger son repented, and the daughters-in-law were moved by him and became more filial. The whole family worked together to make a fortune, and finally staged a heartwarming scene of daughters-in-law competing to provide for themselves in old age.
