Criminal Investigation: Chasing the Murderer

When Lu Chen, a grassroots criminal policeman, first joined the criminal investigation team, he encountered a corpse dumping case on a rainy night - there were no fingerprints or witnesses at the scene, and only a vague shoe print was left. The method of this case perfectly overlapped with the unsolved case three years ago. As the investigation deepened, he discovered that a secret organization was involved behind the deceased. What was even more strange was that the mole in the team, the altered files, and the witness who suddenly changed his story, all forced him into a desperate situation.
