Beside the school's perimeter wall, in the greenery, two security guards were a bit baffled.
Security guard Zheng was the most experienced of the bunch; he had worked at a high school in a small city where he was used to teaming up with the head of the student affairs office to catch rebellious students scaling the walls.
He felt that from the direction of the person's gaze and the commotion just now, it was very likely that he was looking for a place to hop over the wall.
So, Zheng positioned himself in a hidden corner on this side of the wall to lie in wait and used his walkie-talkie to alert the other security guards.
There was no helping it; Technology University was just too big.
If this old thing really wanted to scale the wall, who knew where he would choose to start?
Thus, relying solely on Zheng clearly wouldn't do; it was necessary to call in more people to keep watch.
