Huo Ji and Criminal Investigation jointly investigated the case at the explosion site, and found many fragmented clues and equipment wreckage. It was confirmed that the factory was engaged in drug production. After analysis by Wu Yong and the anti-drug police, they concluded that Han Pei took over the Han Group a year ago, and the anti-drug police found clues. Han Pei died half a year ago, and the anti-drug police cut off the clues, so the drug producer was Han Pei, but Han Pei was dead, and the drug production was restarted. The current controller is likely to be Han Jun or Gao Weiyuan.When the police asked Han Jun, Han Jun said that he was completely unaware of drug production, and that his mother died of drugs. Han Jun accused Han Pei of actually making drugs.Shen Yi rushed to the hospital to visit Shen Ye, saying that nothing had happened. Shen Ye also said that this time he was just an accident at work. Shen Yi seemed to be caring about Shen Ye, but in fact the father and son had their own thoughts.The police went to arrest Li Si and inquired about Fan Yi's family. Some evidence was found in Fan Yi's home, which were exactly consistent with the footprints left at the explosion site.The police inquired about Gao Weiyuan. At first, Gao Weiyuan argued that he was just going back to take a look. Under the evidence and inquiry, Gao Weiyuan fabricated that he was following Fan Yi to the factory, saying that the bomb was released by Fan Yi, and Fan Yi wanted to die with Xu Tongsheng, but he was completely innocent.
