Lin Dagen crosses over into the material-scarce 1970s, where his family is poor and he must face the harsh, greedy mother-in-law, Old Lady Wang. In the desperate situation, the pick-up system activates, guiding him to unearth forgotten treasures in mountains, fields, and old warehouses. His wife Su Yulian is wise and insightful, and the two tacitly join forces, quietly picking up leaks while doing chores on the mountain, accumulating family wealth bit by bit. Old Lady Wang, full of jealousy, secretly pries and sets up obstacles everywhere, always wanting to snatch their money-making avenues. Relying on the system and his resourcefulness, Lin Dagen resolves crises one after another, going from setting up a stall in a mountain village to opening a shop in the city, breaking through rumors and calculations, and forging a path to wealth with his wife in the 1970s.
