The Bullet Is on the Left, the Scam Is on the Right

Lin Guodong, the city's top trace inspection expert, was mysteriously shot in his study. All the evidence at the scene pointed to suicide, except that the door was locked from the outside. The only person who holds the secret of the spare key to the study is the apprentice and trace inspector Chen Mo who he brought out personally. When Chen Mo tremblingly hid the key that was supposed to be in the secret compartment and pinched a bright blue metal fragment that did not belong to any bullet in the barrel of the "suicide" pistol, he knew that his mentor died in a perfect murder. However, the carefully laid trap has just been launched. His back appeared in the deleted surveillance video, unexplained anonymous text messages revealed his secret by name, and deadly snipers were waiting in the dark. Suspended, hunted, framed... The conclusion of the police report ran counter to the truth he was seeking. From weird recordings with mixed voiceprints, to key physical evidence taken away late at night; from huge financial frauds, to art galleries hiding military-grade encrypted hard drives... Every clue points to a bigger shady story, and every answer is the beginning of a more dangerous mystery. Bullets are fired from the left, roaring with deadly precision; deception is woven from the right, shrouding trust and order. When criminal investigation technology encounters criminal psychology, and when the logic that he adheres to becomes a tool of conspiracy, Chen Mo must tear apart the truth behind the cobalt blue fragment that is enough to swallow everything before everything is irreversible.
