The story begins in a year of famine. Li Yi unexpectedly travels through time to an era of severe scarcity, where his household has only a little leftover grain and two suffering women. At a critical moment, he awakens a survival system and gradually supports his little family through hunting, gathering medicinal herbs, and trading for food. From pheasants and rabbits to granaries overflowing with grain and meat, from a broken stove and a cold house to warm kang beds and hot meals, he protects Qiao Qian and Xue'er while dealing with troublemakers in the village and schemes in the county town. The barren mountains become his granary, and the dilapidated house will eventually become a secure home that everyone envies. Life grows better and more hopeful with each passing day, bringing sweetness, warmth, and satisfying triumphs.
