Chen Nan travels back in time to the 1960s, with a portable jade space capable of growing spiritual fields and storing items. The original owner was plotted against, fell into the water, and died. At home, there are parents and nine young younger sisters, making livelihood difficult. Relying on the space's output of food and vegetables to improve meals, buy clothes to care for his sisters, and teach them to read, Chen Nan cleverly uses supplies to exchange for ration tickets, resolves the crisis of false accusations and home ransacking, breaks the prejudice of valuing boys over girls, and single-handedly guards the whole family to live in peace and stability.
