Scientific researcher Shen He accidentally time-traveled to a severe drought barren year. The original body was arrogant and selfish, emptying out the entire family's fortune, single-mindedly pouring affection on the scumbag Chen Shi'an. After time-traveling, Shen He awakens a system, holding fast-growing spirit fields and spirit springs. She changes her old ways, wholeheartedly protects her simple family members, fiercely counterattacks Chen Shi'an's family, and takes back the usurped family property. Relying on the grain produced by the system as well as discovering wild kudzu, Jerusalem artichokes, and other grains, the family shakes off hunger and cold. Subsequently, Shen He leads the villagers to find underground water sources, improve saline-alkali land, and freely distribute good seeds, transforming from a wicked woman spurned by everyone into a trusted guide for the entire village, leading the folks to find a way to survive in a desperate situation.
