A 985-graduate female entrepreneur-turned-boss time-travels to become a second-branch daughter-in-law, living in a broken house, farming barren land, and being plotted against everywhere by the eldest branch. Relying on her knowledge, she leads the whole family step by step, gathering herbs on the mountain and making crayfish, taking it one step at a time from not having enough to eat to living in a grand mansion. The eldest branch plays dirty step by step, ultimately digging their own graves into prison. Watch how the wise wife supports a house of poor bones, counterattacking and slapping faces.
