Li Yi was adopted by his father, a Taoist physician, from a young age and learned all-round medical skills. Before the master passed away with regret, he told him the truth about the grudges twenty years ago. Suffering from a stubborn illness, he took the civet Dahei down the mountain to seek refuge with his uncle Wu Haifeng. While recuperating his body, he secretly investigated the truth. In Tianhai City, he used the method of seeing, hearing, asking and understanding taught by his master to solve the strange diseases that the hospital was unable to deal with one after another, and won the respect of patients with his benevolence and benevolence. There is no violent revenge, only the wisdom of repaying evil with kindness; instead of relying on golden fingers, it relies on solid Chinese medicine skills and a firm heart. The three views are super righteous, and the refreshing point is down-to-earth. Let's see how the young miracle doctor protects his master's legacy in the city and embarks on a warm road to help the world.
