Li Dong is a technician in the Hualing Mining Production Department. He found that the materials for the silver refining project were shoddy. As a licker, he chose to sign the contract due to the threat of divorce from his wife Zhang Ting. An accident occurred in the project and seven people died. Li Dong took the blame and was sentenced to five years in prison. After he was released from prison, he caught Zhang Ting and Jiang Haichao having an affair in the parking lot. Li Dong wanted to strangle Jiang Haichao to death, but the man and woman killed him instead. I regretted it so much before I died. If there was an afterlife, I would definitely find someone to support me, stop being a bitch, and follow the right path.
