Pastry chef Su Wan opens her eyes to find herself transported to the material-scarce year of 1960, becoming a bullied young daughter-in-law of the Lu family. The original owner was beaten and scolded by her mother-in-law for secretly eating half a sweet potato, dying of cold and hunger, leaving her with toxic in-laws and a disabled, wounded veteran husband mocked by the villagers as a cripple, Lu Yanci. Unwilling to continue swallowing her anger, Su Wan boldly demands to divide the family, moving into a leaky thatched cottage at the east end of the village. Accidentally awakening a spirit spring space, the spring water can nourish the body and store things to keep them fresh. She turns coarse grains into fine food, tinkering with various wild vegetable buns and oil-oozing salted eggs; she reclaims her reserved plot of land and goes into the mountains to gather mountain goods to trade for supplies.
