Just when everyone was waiting for Lao Chen to be exposed, the test results came out. Lao Chen's leg was indeed injured and fractured a few years ago.Lu Zhengyang suspected that he was wrong, but he analyzed it again with Lin Shaobai and Li Yaohong and found that Lao Chen was pretending to be confused before. He first refused to go to the hospital, making people suspect that he had a problem, and then used the test results to prove his innocence.It turns out that Zheng Lanting arranged for him to infiltrate our party four years ago. In order to play “Old Chen” well, he cruelly broke his own calf. To him, this is a medal for serving the party and the country.
Ningbo called back and Li Yuquan didn't go to Ningbo at all.Lu Zhengyang went to the sugar factory and only found a “confession”.The letter explained how he provided white phosphorus to Zheng Lanting and assisted Ogura in producing anthrax bacteria.The police found the laboratory hidden in the sugar factory, but by this time Ogura had been transferred.Jin Yan tested the petri dishes brought back by Lu Zhengyang and found that the Sugar Research Center was the real source of contamination by the anthrax bacteria.
Cen Xiaoman expressed doubts about the authenticity of the confession, while Lin Shaobai deduced from the details that the confession was indeed written by Li Yuquan.Lin Shaobai and Lin's mother went to appease Li Yuquan's wife and found a key in the chess piece with the words “Jian'an 403” written on it.Lin Shaobai and Lu Zhengyang found Jian'an Apartment. Li Yuquan was indeed there, but he had become a corpse.Lu Zhengyang and Lin Shaobai found a bomb at the scene, which was exactly the same as the one found when Wang Liqun was transported.
