In the Tiandu Dynasty, the imperial power changed and the powerful ministers changed. The three heroes of the market, Du Xianyu, Yan Ziqiu, and Lao Qian, accidentally entered the palace struggle, met the cold-faced powerful minister Han Jun, and the mysterious maid Asu, and moved from the arena to the dynasty, and then stirred up the storm in a foreign country. The protagonist and his party continue to break through the rapids of history, political games, family grievances, ordinary people's lives, and strange cases, and each of them grows and transforms. The story connects multiple clues in a relaxed and humorous style, creating a fictional yet realistic portrait of the dynasty. The black humor is full of warmth and thinking.
