This is a world intertwined with history and fantasy. The Chu Dynasty stands in the world. On the surface, the country is peaceful and the people are safe, but in fact, there are undercurrents. There are many sects in the world, each with their own agenda; above the court, various forces are fighting for power to the death; and in the dark, mysterious evil forces quietly rise, trying to subvert the world. The imperial court has a Shendu Department, which is responsible for handling all kinds of supernatural and evil cases and maintaining order in the world.
