Finally, it reached midday. A middle-aged man in a shirt and with a goatee slowly pushed open the doors of the auditorium and walked in, casually locking the door behind him.,"There are simply too many people here! From this moment on, only fifty people will be allowed to remain in this auditorium. The rest must be eliminated. Remember, you can harm others, but taking a life is absolutely forbidden.","If anyone dares to make a move, they will be immediately expelled. Everyone, give it your all! Fight until the very end!"。
