Liu Yang and Wang Zihao were transferred to the Yougu City Police Station and took over a murder case of a rich man.
"Who killed the rich man? What did the rich man do?"
"Who is the suspect? Why did the cleaning lady appear in the rich man's office? What is the cleaning lady's alibi?"
"Secret room murder? Missing witnesses? Man's body in the sewer?"
"Who is the identity of the man in black? Who sent the anonymous email? Is someone guiding us in handling the case?"
Purpose: As long as it is committed by humans, even if it is a seamless crime, there is no unsolvable reason.
