Jiangzhou Senior High School's No. 4 Teaching Building had seven floors, with the rooftop situated above the seventh.
The rooftop was spacious, with nothing but concrete ground. Surrounding it was a concrete safety railing about one and a half meters high to prevent students from falling.
Usually, the door from the seventh-floor stairwell to the rooftop was locked. However, some students always managed to get a key and open it.
At this moment, the rooftop door had been opened and then locked again from the inside. On the rooftop, there were only Meng Zelong's group of three and Lin Feng.
Behind the rooftop door, Yang Tao, Tang Wan, and others waited anxiously, fearing something had gone wrong. Yang Tao had already reported this to their Head Teacher. However, the Head Teacher was temporarily out of school, so Yang Tao had then sought out their English teacher, Cao Ying, who was now on her way.
