[Playground Area]
A group of workers from the surveillance room had already set up an IMAX-level giant screen on the playground, displaying the real-time surveillance footage of the self-study session.
During the evening self-study, the teachers generally had little to do.
Some teachers who were more concerned about their students,
or those who liked to watch killing games,
or simply wanted to gather and chat with others,
would bring some late-night snacks, beer, sunflower seeds, peanuts, or even invite a BBQ team from the cafeteria to the playground, sitting on the ground to enjoy their leisurely night.
Of course, most of them came for entertainment and didn't really believe any students would reach the principal's office.
The so-called "Shadow Students" are built on heaps of corpses, and among tens of thousands of students, perhaps one might survive the evening self-study session.
