This book tells the story of Meng Lai, a green-skinned intern police officer who can see the color of a person's energy field, thus predicting their mood, next move, and even their crime rate. While Bai Yu and Meng Lai are fixing a security vulnerability in a computer, someone has planted a large number of butterfly-shaped high-risk viruses. Surveillance footage shows the person opening the computer—a blurry figure, seemingly someone with the ability to fold their body. An investigation reveals that the computer's owner had died a month earlier; he was the last victim in a murder case. The killer first hacked into the victims' computers, using the stolen privacy to blackmail them, luring them to a pre-arranged location, trapping them, and then murdering them. The criminal profiler engages in a battle of wits with the suspect, ultimately uncovering the conspiracy of the W Group, the mastermind behind the crime.
