1925, Shanghai. This city is in a turbulent era, with Eastern and Western cultures intertwined, political forces complex, and undercurrents of gangs. But ordinary people wandering in the smoke under high-rise buildings often don't know that they are just a speck of dust in the historical tide. Shanghai, this legendary city, is waiting for a wise man who can solve its many mysteries.
Li Han, a young detective wearing a long gown and sharp eyes, is a legend in this city. Although he is young, he has already become famous due to a series of incredible experiences in solving crimes. Many people say that his eyes can see through people's hearts, his methods are better than those of the police, and his style of handling cases is both calm and ruthless. Li Han is not only proficient in Western detective skills, but also has a profound background in traditional Chinese medicine and has unique insights into the analysis and pathology of the human heart.
Today, the bustling Shanghai Bund is still there, with neon lights lighting up the night sky on the Bund. In a seemingly ordinary teahouse, Li Han is sitting at a small table, drinking tea and quietly waiting for a guest.
