I am a monitor, and I work shifts during the day and night with my colleagues. Sometimes there is no problem when working shifts. But tonight, several large screens suddenly flashed. I thought it was a power problem, so I didn't pay attention. I also asked the patrol master to patrol the corridors to see if there were any emergencies. I felt very uneasy. At twelve o'clock, the small clock on the desktop suddenly rang. My colleagues were dozing off. I was still staring at the screen. I felt like something happened tonight.
