On October 1, a year ago, eight students from Middle School A played a "killing game" with cards in the school. Before the game started, they were locked up in the school because they missed the closing time of the school. During the seven-day National Day holiday, the "murdering game" that had not yet started had "started", and students among the eight students were murdered one after another. Until the last day, there were four students left: Cui Shanshan, Huang Siming, Mu Yi, and Xie Jiayi. At this time, Huang Siming and Xie Jiayi deduced that the final murderer was Mu Yi and were rescued. Mu Yi was arrested by the police for the murder, and Cui Shanshan was sent to the hospital because he was stabbed by Mu Yi. This "killing game" ends here...
And a year later...
