This is the most elegant murder and the most arrogant provocation.
The murderer used symbols to write his criminal declaration and used a span of fifteen years to prove his patience.
He killed people not only to silence them, but also to complete a "harvest" that was twenty years late.
And Lu Chen's pursuit is bringing him step by step into the center of the "Reaper's" field of vision.
In an abandoned sanatorium, Li Guohua, a professor of history at a well-known domestic university and an expert on semiotics, was killed. The case was surprisingly similar to the 0917 series of cases fifteen years ago. What is even more puzzling is that Zhao Ming and Li Guohua, the victims of a case three years ago, were both experimental subjects of secret research projects during the Cold War. After so many years, experimental subjects were frequently killed. Lu Chen, the police officer who investigated the case, was also one of the targets. What was the purpose of this? What's the ultimate secret to that secret project? Who is the real murderer? Why are you so familiar with police work? Could he be a mole hiding in the police force?
