Sonic Judgement Episode 1

A young boy named Qin Le Le was abducted near Jinmen Community and called the police for help using his smartwatch. Audio-visual expert Jiang Cheng, relying on his exceptional hearing, gradually deduced from the vague clues provided by the boy that he might be trapped in the basement of an old residential building. Criminal Police Officer Su Ling Yu led his team to act swiftly, successfully rescuing the hostage and capturing the human trafficker. Shortly after, the body of a man with his mouth sewn shut was found in an abandoned factory. The forensic doctor initially identified the deceased as Li Xiu Ping, a financial professional. From the audio recording extracted from the deceased's phone, the police discovered that he had been kidnapped and threatened before his death, which was related to a transaction involving his younger sister Li Xiu Yan and 25 kilograms of gold. Through voice analysis, Jiang Cheng pointed out that the kidnapper used a voice mimicry template to disguise his identity, and his accent suggested he might be from the northern part of the country. Further investigation revealed that Li Xiuping might be involved in illegally manipulating clients' funds for transactions, leaving numerous doubts behind the case. (Source: iQIYI)
