Tian Bufan said, "I needed to confirm what behavior the nocturnal species inside the elevator would exhibit before the sun completely set."
"According to the Art Student Rules, we can infer that the elevator in the teaching building must be emptied at night, so that art students can take the elevator to leave. In other words, they would leave the elevator at an appropriate time."
"Have you troubled another elevator's nocturnal species?"
"Not this time, it was only observation."
"So, what did you see?"
"Wei Shan and I were squatting outside the elevator corridor. At first, we didn't notice anything until I saw a non-human classmate dragging his feet past us, and then he went to open the elevator."
"That was around 17:50, which is when the sun completely sets and the layers of the campus begin to fall."
