Ye Xixia, a powerful survivor from the post-apocalyptic world, transmigrates into the body of an official's daughter sentenced to exile. During a forced marriage arrangement, she chooses Lu Chuan, an assistant postmaster, and they agree to build a household together without relying on him to support her. Blessed with a wood-type supernatural ability, she ventures into the mountains to gather rare wild produce and cultivates mushroom beds. Liu Yuemei grows jealous and persuades her husband to borrow money for a lavish banquet to compete with them. Ye Xixia uses tea as an ingredient to prepare a distinctive tea-infused feast, winning everyone over with her ingenuity and kindness toward her neighbors. As the couple gradually open their hearts to each other, Ye Xixia reclaims wasteland and builds a livelihood, laying the foundation for Lu Chuan to earn military distinction and eventually become a marquis.
