In her previous life, after her grandmother split up the family, she and her relatives were left wandering homeless, enduring endless suffering and tears. In this life, Chen Xiaosui refuses to endure mistreatment any longer. Relying on her system to identify medicinal herbs and exchange them for money and food, she begins rebuilding their lives. After her father, Chen Shitou, returns from the brink of death, he takes responsibility for supporting their small family. Lin Ye, a skilled hunter who owes Chen Shitou his life, repeatedly comes to their aid. Greedy relatives keep showing up to seize their medicinal herbs, forcing the family to stand together and fight back. To escape famine and the schemes of their neighbors, Chen Xiaosui decides to take the entire family deep into the mountains and establish a home there. By gathering herbs, hunting, stockpiling supplies, and relying on her medical skills and the resources of the mountains and forests, they carve out a stable livelihood amid a chaotic era.
