The story takes place in the "Jiang City" under the background of a modern city. On the surface, this city is a second-tier hub city with prosperous economy and orderly order. In fact, it hides three major power circles, forming a special ecology of "a bright city and a hidden river and lake". On the surface, business families such as the Liu family and the Su family dominate the economic structure, relying on real estate, medicine, finance and other industries to control the lifeblood of the city; the middle-level are the maintainers of order composed of the police and official forces, responsible for handling routine security incidents; secretly, there is a secret world composed of the ancient martial arts family, the hidden sect and the "Zhenguowei". These forces have power beyond ordinary people, follow unique rules, check and balance each other and occasionally clash with each other.
