In the 14th year of the Republic of China, in Tianjin Wei, Cui Xiaoqi, a disciple of Qianmen, used the "Bee Sparrow" technique to wander around the docks, only to make money and often help the lonely and weak. After meeting his master's junior brother Shen Moru by chance, he inherited the "Secret Records of a Thousand Gates" and set up a bureau with Su Wanqing, a former Qing Dynasty gege, to outsmart the Japanese invaders Matsumoto Ichiro who was searching for cultural relics.
