Su Wanqing, the successor of traditional Chinese medicine, broke her peaceful life of hiding in the market with a reward. Mission goal: cure Fu Yunshen, a man who is extremely wealthy but is plagued by strange diseases and imprisoned in a lonely castle. When we first met him, he was as cold as ice, and there was an unbreakable alienation and suspicion in his eyes. "Get out." She took it indifferently, put her finger on his pulse, and said something shocking. "Mr. Fu, your pulse says that you are not sick, but too lonely." In a transaction in the name of medical treatment, he went from resistance, to temptation, to complete dependence. She became a drug he couldn't quit, a warmth he couldn't live without. Just when he was about to bring the whole world to her, her master who had never seen the dragon suddenly appeared and revealed the secret: "Silly girl, what's on him is not a disease, it's the 'seven-star life-extending' curse. What you cured is just the appearance." When the logic of a modern business empire collides with the ancient and mysterious Eastern heritage, a love affair about healing, trust and destiny begins.
