On the day Chu Ning was transferred to the technical department, her colleagues told her: The lie detector is just a display, and only those who believe it will be useful. She didn't believe it. It wasn't until she was interrogating the suspect in the murder case in Qingshanguan that a picture suddenly popped up in her mind - the deceased kowtowed in front of the incense burner, with a person standing behind him. That person is not a suspect. From then on, Chu Ning discovered that his lie detection did not rely on machines. She relies on 'over-voltage'. Every time she passes electricity, she can see what others hide in their deepest parts. But ability is a double-edged sword. The deeper you look, the deeper you sink. When she found out that her father's death was related to Qingshan Temple, she couldn't pull it out.
