As Director Wang spoke, the expressions of several people in the room changed instantly.
The principal's eyes were full of doubt, "The surveillance was working fine, how could it suddenly break?"
Teacher Li frowned, her unease growing by the minute.
As a teacher, Teacher Li knew that the classroom surveillance had long been upgraded to a more intelligent network system, with real-time uploads to the platform, making it convenient to access at any time.
Director Wang had just been evasive about checking the surveillance footage; it turned out the videos were missing! But how could videos that were properly uploaded to the network system disappear, especially just at this time? It was too much...
Teacher Li dared not continue thinking about it.
