The story describes that in order to consolidate its dominant position, Yongzheng of the Qing Dynasty organized the assassination group "Blood Dizi" as a tool to kill dissidents. Sometimes a guard led Han Tiande, who inadvertently found that Yongzheng was the mastermind behind the blood dripping son, which led to the destruction of the whole family. Only his wife, Rong Qiuyan (Chen Ping), went out because of the incident and survived. It was later found that it was "Blood dripping son" who led Jin Yifeng (Luo lie). Later, he alone went to the Jin mansion to assassinate and tried to avenge the whole family, but he was forced to flee because of a fall short of success. Jin mobilized hands to pursue it. On the way, he met his brother Wang Jun (played by Yue Hua), only to find that Wang Naijin had an illegitimate child, who was killed many times and was finally killed by Rong. After getting the former "Blood Dizi" member Ma Teng (Xu Shaoqiang) to help, overcome all difficulties, and eventually kill Jin to avenge his husband.
