Sonic Judgement Episode 13

The police press forward step by step based on the voice evidence extracted from the robot vacuum cleaner, but Chen Lu remains silent in the face of irrefutable evidence. Su Ling Yu reveals the real cause of Liu Wen Tao's death: a fatal combination of taking digoxin and being exposed to high-frequency sound waves. A recording stating "Confirm he's dead" becomes a breakthrough. As surveillance footage, voice recordings, and witness testimonies pile up, Chen Lu finally breaks down emotionally and admits that she did return to the crime scene. Flashbacks reveal Chen Lu's experience of being oppressed at home since childhood, as well as her complicated relationship with Li Yao Hui. Chen Lu once plotted extortion with Li Yao Hui, manipulating an old man to provide them with money. However, after Li Yao Hui showed fear, Chen Lu gradually lost all illusions about him and finally decided to kill him. Chen Lu admits that she used her husband's insurance and will to gain benefits, and her underlying motives are gradually exposed. Chen Lu coldly states that she is emotionally detached, and all her murders were committed for profit. Finally, she reveals how she planned Liu Wen Tao's death. (Source: iQIYI)
