Su Wen, heir to Shennong Valley, possesses the medical arts of Guigu and the Book of Life and Death. To cure his Nine-Yang Absolute Meridian condition, he descends the mountain to fulfill a marriage agreement, only to be publicly rejected by his fiancée, Lu Xuanyi. Lu Wan Feng, the disabled orphan of the Lu family, courageously steps in to marry him instead. After their wedding, Su Wen disguises himself as an ordinary country bumpkin. Using his rare treasures, medical expertise, and appraisal skills, he repeatedly humiliates the Lu family members who look down on him and Lu Wan Feng. He cures her disability, secures a partnership with the Zhu family, and resolves a construction-site scam and a deadly feng shui incident. Meanwhile, he conceals his true identity as the powerful figure behind the Luyue Chamber of Commerce, before whom even underground kingpins bow in submission. As the contractual couple gradually fall deeply in love, Su Wen sets out to find his master to repair an ancient monument of the dragon vein, bringing the first season to a temporary close.
