Modern ordinary people accidentally traveled to ancient times and became Lan Xi'er, the mistress of the Xu family in Yanya City. Her husband, Xu Jialing, had not returned from studying abroad for five years. She had to raise her three sons and take care of the family's property alone. Although the Xu family has thousands of acres of fields and mountains and forests, they have little surplus due to poor soil and poor management. Lan Xier gradually improves her family's situation with the help of modern knowledge.
