My name is Xu Fei. I have been a police officer for many years and have handled countless bizarre cases. Among them, what I don't believe the most are the victims and witnesses, because these people will suddenly change their minds due to some reasons, but the clues I have traced out have no possibility of changing their minds. And in my many years of police career, there is a prisoner named Gao Feng who always makes me feel scared. There is no peak in this story, and he is everywhere.
