Got tricked momentarily 2

Leng Xuan, since elementary school, had never formally attended school. Although he had learned a lot of things within the organization, they were mostly practical subjects. As for the questions on this high school senior's exam paper, he really struggled with some of them. Holding a pen, he managed to do the easy ones, yet many were left blank, clueless about where to even begin. Suddenly, he saw Pang Shanshan walking over to his side, probably because she noticed he hadn't written anything for a while and her gaze hadn't moved from him, which was quite frustrating. He pretended to scribble on the exam paper.

Pang Shanshan frowned slightly, curious to check out what this student Leng, who had just transferred a few days ago, was actually up to. Just as she reached behind Leng Xuan, suddenly, it felt like she stepped on something, and a faint cracking sound followed.
