Niu Xiaolan, the guardian of the inheritance of traditional Chinese medicine, was left at the door of Niu's house by a mysterious man eighteen years ago and was adopted by the Niu family's grandfather. Eighteen years later, he was ordered by his master to go down the mountain and return to Yuncheng, just when his grandfather was critically ill. Relying on the long-lost "Nine Needles to Return Yang", Niu Xiaolan saved her grandfather and officially entered the wealthy Niu family.
However, the adopted son of the Niu family, Niu Xiaobao, covets the family property and colludes with the international pharmaceutical group "Eternal Life Palace" to frame the protagonist many times. Niu Xiaolan relied on her superb medical skills and extraordinary wisdom to resolve crises time and time again: she saw through poisoned wine at a banquet, cured ALS patients in a live broadcast, and made a dandy embarrassed in public at an auction, gradually establishing her position as the heir to the Niu family.
As the investigation deepened, Niu Xiaolan discovered that the mystery of his life experience was closely connected with the "Qing Sang Sutra" inherited from traditional Chinese medicine. The biological parents are still alive, but they are the inheritance guardians of the previous generation. They were hunted down by the Palace of Immortality for protecting medical books. On your twentieth birthday, you will be faced with a fate of life and death.
In the end, Niu Xiaolan led the three sisters of the Niu family to unite all forces to destroy the secret base of the Palace of Eternal Life, rescue her parents, and completely crush the villain's conspiracy. After becoming famous, he chose to retire and hand over the Niu Group to professional managers. He traveled around the world to pass down traditional Chinese medicine, leaving behind the immortal legend of "Miracle Doctor Niu Xiaolan".
