Xu Xiangyang felt that something was not right...
No, it was very wrong.
He took a deep breath, didn't immediately run back, but continued walking to the side of the security room.
He turned around and stared at the pitch-black corridor for a good while. The entire second floor only had class five still occupied, so it was just outside class five that the lights were on. Unless everyone inside had left, the lights wouldn't be off.
Would someone turn off the lights just for a quick trip to the bathroom or to pour a glass of water? Moreover, it was only the girls who had temporarily left, and when they came out, there were still two boys in the classroom.
Could this... be considered a prank?
Xu Xiangyang knocked on the door, but there was no response. He went to the window next to it, stood on his tiptoes to look inside, but saw no one.
The door wasn't locked, and it opened with a light push; the security room was indeed empty, not a soul in sight.
