The down-and-out prince Qin Chuan was given the gift of marriage to the eldest princess Zhao Shuyi, and led the Zhenbei Army to garrison the border. Supposed by the commander-in-chief Yuan He, he was sent to attack Black Rock City. He cleverly planned to pacify the gangs in the city and conquer Chen Guangming. The Southern Barbarians invaded on a large scale. Qin Chuan used clever tactics to defeat the enemy army. He went deep into the barbarian camp alone to burn the food and grass, outsmarted the enemy city, poisoned the barbarian commander Hu Zun, and defeated the main force of the barbarian army. After returning to Beijing, he smashed the conspiracy of the prince Zhao Yuan and the Black Fu organization to seize power, uncovered the traitors such as his uncle Guo, stabilized the great martial arts, and stayed with Zhao Shu.
