The security guard obediently hit the Space bar and the surveillance video playing on the computer paused.
Du Mingwei turned around and asked the person beside him in surprise, "Teacher Luo, do you know this person?"
The female professor looked at the girl on the monitor and shook her head in confusion. "I don't think I've seen her before. She's not a student from our department."
Du Mingwei nodded, quite sure. "I've never seen this girl before, either. She's not a computing student."
After saying that, he pursed his lips. He was unwilling to guess the innocence of a student without evidence, but he still expressed his doubts implicitly. "Principal Liang, we only called a few people from the Computing faculty to help move things. This girl is not from our department."
