Grudges from previous generations
Feng Minyang is a member of the tomb robbing group. He accidentally met Zuo Yuming and the two became good friends. Zuo Yuming suspected Feng Minyang's identity. As a policeman, he and Feng Minyang robbed the tomb together and collected a lot of evidence. However, the tomb robbers discovered Zuo Yuming's identity. Feng Minyang was asked to kill Zuo Yuming within a week. Feng Minyang finally failed, leading to the brutal deaths of his wives Xi Ruixue and Zuo Mingming. Zuo Mingming's wife Hu Jia (who is also Feng Minyang's high school classmate) continues her husband's career and vows to crush the tomb robbing syndicate. Feng Minyang also broke away from the tomb robbing group and lived an anonymous life.
