Although Qin Shuang was anxious to go upstairs to check on the situation, she obediently followed behind her when she heard Xue Xi's words.
The two of them circled around the school building and Xue Xi stopped on one spot. She extended her hand and gestured in mid-air.
Qin Shuang was baffled and asked, "Sister Xi, what are you doing?"
Xue Xi: "Drawing the structure of this building."
Qin Shuang looked at the empty air in front of her.
Xue Xi focused on the sky. She had a photographic memory and had just gone looking for CCTV footage.
The surveillance cameras in the education block were useless. After all, the only place they could capture was the corridor. They would definitely not be able to see what happened to Qin Lu inside Old Liu's office, so Xue Xi was paying attention to the surveillance cameras outside.
