Reborn in the 1960s: With the System in Hand, I'll Spoil My Third Sister

During the 1960 famine in Jiangbei, modern agriculture professor Lu Ming is reborn and collapses from hunger in a field furrow. Clutching half a moldy sweet potato, he binds to the All-Purpose Family Support System and gains a healing spirit spring, a 10-square-meter pocket farm, and an agricultural encyclopedia. He rushes back to their rundown home and uses the spirit spring to save his second sister, Lu Xue, a barefoot doctor who ate poisonous weeds by mistake. He helps his third sister, Lu Shuang, a Tsinghua prodigy sent down to the countryside, hide her student ID from the Red Guards, and teaches his fourth sister, Lu Bing, who is deaf and mute but mechanically gifted, to repair a tractor.

With the System's help, he grows two rice crops a year in saline soil and uses biogas to light up the whole village, only to be reported for "promoting capitalism." When the Red Armbands come knocking, the general's token he keeps close reveals his identity, while the System's manual hides core data on hybrid rice. Foreign spies set their sights on the experimental fields, and the rugged village team leader risks his life to protect them. As the siblings fight famine and protect their talents, Lu Ming has no idea that the general's token has set him on a revolutionary mission, and spies are far from the only ones watching the System...
