First, Gao Mingyuan received the news of Chen Jianbo's arrest. At that time, He Yong led a team to Weilongshan to look for Xue Mei's body. After Gao Mingyuan got the news, he asked Chen Jianbo to transfer the body, but he didn't expect to be hit by He Yong because he ate hot pot and delayed the transfer of the body. Chen Jianbo was taken back to the police station. Chen Jianbo's trial was also presided over by Peivie and He Yong, so it is possible for Peivie to convey the change of Chen Jianbo's attitude.
Second, He Yun received a short message from Gao Mingyuan. Gao Mingyuan knew the news of Chen Jianbo's arrest, but he was not very worried and had no intention of killing Chen Jianbo. Because he knew that He Yong had no evidence, he sent a message to Chen Jianbo to keep it for 24 hours. At this moment, He Yun hung up the phone and stood up to find He Yong. When He Yong went out, Peivie spilled water on Chen Jianbo, and Chen Jianbo changed his attitude and said nothing.
Third, He Yun and He Yong came to report. But He Yong also said, strangely, Chen Jianbo's attitude change is unbelievable. But He Yong only suspected He Yun at that time, so he invited He Yun to report with him. At the time of reporting, he quickly reported the situation in Chen Jianbo. After listening to He Yun's report, Luo made a decision to release and was released. So Peivie is probably the mole, and He Yun is in it.
