防御系统自主运行，一阵短暂而急促的的警报声响起，厚重的合金门随即落下。
自此，演唱会厅彻底变成了与世隔离的孤岛，没有任何物理缝隙允许任何人在不破坏防御体系的前提下进出。
【The internal autonomous network system has been started. Authorized members are requested to connect to the internal network through the previously issued channel for internal connection. The autonomous network defense system will reject any unauthorized personnel's access and immediately reverse locate the unauthorized network address and kill it. The autonomous oxygen supply system has been started normally and has successfully taken over the internal oxygen supply safety. It is expected to last for 80 hours of continuous oxygen supply, with an internal oxygen content of 21% and an atmospheric pressure of 101 kPa. If the atmospheric pressure is different from the normal value, it may automatically connect the second oxygen supply system and the second atmospheric pressure stabilization system. The system has pleted automatic inspection, please plete the manual secondary inspection】
紧接着是封闭网路系统的自启动与授权下发，第一供氧系统的启动与第二供氧系统的检查与大气稳定系统的自动检测。
一切正常，演唱会正式开始。
