I am a mystery. The murderer is Antonio. Because Antonio took advantage of Augustine's fear of Barron, his confidant, the tattooed man Stu, put the forged cooperation letter into General Barron's study through Caesar, thus eradicating Augustine's "right hand man". I am a mystery and a manuscript-killing game, and the realm is a story in this manuscript-killing game. Players can substitute various characters to interpret a large number of scripts and experience the complicated brain-burning reasoning process, which is deeply loved by young people.
