Zhan shisen is caught on a road surveillance camera taking part in the murder of his wife. He's also caught in the act of hiding and moving his wife's body. The two men are wearing green glasses, which can sense human eye movements. They belong to the chairman of the lz group, and to his brother, who is also wearing a green pair of glasses. They're both in the same villa, which means that they raped the same woman. Zhan is lying, he says, because the traces of his semen on the body of the dead woman are a match to his own dna. That night, after chen and fang left, Zhan drugged fang and she vomited. When he woke up, he saw her jump from the third floor. He called for his wife, but she wasn't dead. She was spitting blood. He and his brother argued about whether or not to save her, but they didn't know that she was pregnant.
