When Zhao Yu told them that he thought that there was a connection between the Tomb Murder Case and the Female Corpse in the Ancient Costume Case from eighteen years ago, the police detectives were divided on how to respond.
Some of them, including Mao Wei, didn't believe that there was any connection between the two cases. But, Zhang Jingfeng and Lianghuan, who were familiar with cold cases, were supportive towards Zhao Yu's hypothesis. They agreed with Zhao Yu's analysis, as both cases were related to the tomb. Hence, it might be the same person's doing!
The reasons that led to Mao Wei's rejection of the idea was that the methods used in both cases were different, and also that the time interval in between the cases was sizable. Da Fei, who also disagreed, had also pointed out that the female corpse in the Ancient Costume Case was strangled, while the Tomb Murder Case victim was killed with a pickaxe! Hence, the methods of murder were completely different!
