Yang Wenfan has carried the memories of several lifetimes since he was born, and relies on these memories. In the world of killers, he stands out among the others, and in the world of finance, he is as rich as anyone in the world. But the inner lack and self-seeking. He began to abandon the life that bored him and pursue the happiness of ordinary people. His superb medical skills allow him to experience all kinds of things in the world in urban life. Ordinary life fills the dry soul. Looking back suddenly, he realized that he got more than he wanted. (PS: Slow-heat article, late stage of literary youth disease. The plot of the TV series is just the background. It can be read as a brand-new article.)
