Just after reading it, I feel that Lin Tung is beginning to want to protect Chen Xue (let's talk about the premise first, I have a rough look, but I haven't looked closely. I think Tong Liner has benefited from Chen Xue before and helped Chen Xue in some ways, so he kept Chen Xue, which will be useful in the future). Zhao Peng said that if Chen Xue didn't die, he would die. In other words, if Zhao Peng had not died, or Zhao Peng had been tried, Chen Xue could not escape. So Lin Tung had to kill Zhao Peng. The police are human beings and will consider their own interests. At the same time, in the fourth part, as the secretary said, the boss gave it to him, so don't try to look up again. The last predator has not yet been discovered. Perfectionists or people with a sense of justice will think that such an ending is contrary to common sense, but in real life, many things are often like this.
