But Dai Li made an unusual move. He arranged for Zheng Yaoxian's entourage to have a man named Gong Shu. He confessed in advance that if Zheng Yaoxian was abnormal, he would be shot. In the conversation with Gong Shu and Zheng Yaoxian, he repeatedly stressed that only he knew the shadow, and no second person knew it, and he didn't want the second person to know it. Seeing that Bian Xiao has a bold guess here, can it be understood as sending Gong Shu to contact the "shadow" to get information and then killing Zheng Yaoxian, and Gong Shu will bring the information back? Because there is too much room for manoeuvre in Dai Li's words, uncle can directly kill Zheng Yaoxian and tell Dai Li that he has signs of pro-* *. Then Dai Li killed Gong Shu. In this case, Dai Li is the only one who knows the man named Shadow. So what Dai Li said is really puzzling. what do you think?
