The core protagonist of "The Mystery of Shenzhen City" is Chen Yan, who is the captain of the Criminal Investigation Detachment of the Shenzhen City Bureau.
Chen Yan has rich criminal investigation experience and keen observation skills. He is calm and thoughtful, and has a strong insight into the details of the case - from the suspicious stab wounds at the scene of Lin Chusheng's "suicide", the neat but deliberate suicide note, to the surveillance abnormalities at the death scene of Zhao Tianhong, he can always catch clues that ordinary people ignore and see through the disguises arranged by the murderer.
At the same time, he has a sense of responsibility and empathy: on the one hand, he persists in pursuing the truth, and never flinches even in the face of dangers such as overseas fraud groups and serial murders, and vows to seek justice for the deceased; on the other hand, he pays special attention to the safety of those involved in the case, such as specially arranging police officers to protect Lin Chusheng's daughter Lin Xiao, and deploying full protection when Shen Man returns to China, showing a warm undertone beyond the hard-core investigative capabilities.
