Educated youth Lin Xiao in the countryside abandoned his wife and daughter in his past life to return to the city, ultimately suffering betrayal. Reborn back to the snowy night when his wife and daughter encountered danger, he resolutely broke with Shen Mengyao, rescued his wife Su Wanqiu and daughter, and awakened the "Lord of the Great Mountain System". To make up for his debts, he went into the mountains to hunt and dig for precious herbs, letting his family eat their fill and keep warm, while also punishing evil neighbors, beating back wolf packs, and winning the trust of the villagers. Afterward, he befriended Master Jin, expanded the mountain goods business, contracted barren mountains to build a greenhouse herb base, led the villagers to wealth, and ultimately achieved career success, having both a son and daughter, staying with Su Wanqiu, and rewriting his family's destiny.
