Lin Yiran, a modern intern doctor, dresses as the second daughter of the Hou family. Her father doesn't care about her, her mother is not around, and her stepmother wants to sell her off. Fortunately, she has a diagnostic system in her hand, and she can look, hear and ask questions without any fuss; she can rejuvenate herself and cure her disease with medicine. Trampling the best, torturing the scum, holding hands with the double-faced prince who fell in love with her at first sight, and living a wonderful life again in ancient times!
