Gu Wanning, an expert in modern agriculture, transforms into the evil mistress of the Hou Mansion who is about to be abandoned and die tragically. In order to protect herself, she turned her enemies into friends internally and became sisters with her four aunts; externally, she battled wits and courage with the cold-faced Marquis Xu Weibei, and gradually developed feelings for her. She relied on her advanced agricultural knowledge to farm and provide disaster relief, uncover the conspiracy of the court, and finally succeeded in clearing her name and counterattacking, helping her husband ascend the throne, becoming a virtuous queen, and working together to create a prosperous age.
