Ten minutes later.
Zhou Ning arrived at the third floor of the staff dormitory building. Liu Yongxin was waiting on the second floor; they hadn't checked this floor yet. After all, Cui Guanglin was not very noticable, and they were also searching for Zhou Xiaoyu here.
Seeing Zhou Ning come up, he quickly followed upstairs. There was no one in the dormitory.
"Open the door; let's check inside," said Zhou Ning.
The guard's face wore an embarrassed expression as he spread his hands and said,
"It's not that we're unwilling to cooperate. The keys to the teachers' dormitories are all in their personal possession. Just now, this gentleman checked, and we had to find someone to open each door for us."
Liu Yongxin nodded in agreement.
"I checked several dormitories downstairs. We need to contact the teachers to open the doors. But everyone is in the multi-function hall, so I didn't manage to find Cui Guanglin's dormitory."
"How many teachers stay in this room?"
