Train Survival Rules

A train traveling through the wilderness suddenly stops, pulling passengers into a WeChat group where everyone is muted. An anonymous user begins speaking, urging all passengers to carefully read the group instructions and memorize the survival rules. Note: You must remember, in this dangerous night, anyone who does not follow the anonymous user's instructions disappears. Driven by fear, I do everything the anonymous user says, even staying silent when my childhood friend vanishes. Finally, I secure the only chance of survival in my carriage. When I step out of the train and rush toward the exit, I witness a shocking scene.
