Shen He, a research scientist, unexpectedly travels back in time to a year of severe drought and famine. Her original self was spoiled and selfish, having squandered the family's entire fortune while obsessively showering her worthless lover, Chen Shi'an, with gifts. After transmigrating, Shen He awakens a system that grants her access to a fast-growing spiritual field and a magical spring. Determined to change her ways, she devotes herself to protecting her honest and kindhearted family, fiercely fights back against Chen Shi'an and his family, and reclaims the family property they seized. With grain produced by her system and wild food sources such as kudzu roots and Jerusalem artichokes, her family finally escapes hunger and cold. Later, Shen He leads the villagers to discover underground water, reclaim saline-alkali land, and freely distribute improved seeds. Once despised as a wicked woman, she becomes the trusted leader of the entire village, guiding her fellow villagers toward survival in their darkest hour.
