Su He, a logistics specialist from the post-apocalyptic world, transmigrates into the body of a maid convicted of a crime and is exiled to the frontier of Liaodong. She must either become a camp servant or marry a general. While everyone competes for Shen Feng, a clever and smooth-talking man, Su He sets her sights on Xiao Zheng, the soldier with the most military achievements, who wants nothing to do with marriage. She boldly approaches him and volunteers to become his wife. The Xiao family is so poor that they struggle to afford food, but Su He secretly possesses a wood-based special ability. She goes into the mountains to gather medicinal herbs and hunt rabbits, quietly improving the family's circumstances. Meanwhile, Su Lan, a maid who once served in the same household, constantly competes with her. The two families arrange to hold their wedding banquets on the same day. In the impoverished frontier, can Su He rely on her own abilities to secure a stable new life?
