Three hundred years after the peace of the Dajing Dynasty, its power gradually declined. There were barbarian cavalry in the north knocking on the pass every year, and there were vassal kings in the south who were separatist and supported their own troops. Above the court, the eunuchs and foreign relatives headed by the chief assistant Zhang Chengye were at odds with each other. The officials were corrupt and the people were in dire straits. In the capital city of Jinling, the young son of Prime Minister Su Hongbo Zi Lu Yuan is a well-known loser in the city. He has been naughty and clueless since he was a child. He spent a lot of money to compete for the courtesan of a brothel. He caused a stir in the city when a horse race knocked over the carriage of the Minister of Household Affairs. He also failed in the imperial examination and provincial examination three years ago and became the laughing stock of the whole world.
