With Wang Jian's constant efforts to search for resources with his colleagues and rescuing survivors along the way, a small fleet was gradually formed. They roamed where they could, hiding from the zombies and searching for usables. Secretary Huang's actual name was Huang Weian and he was the county head of Jiao Yuan County; he and his group of people were all rescued by Wang Jian.
As for the group made up of students, at the beginning of Z-Day, only 12 of them had turned into zombies. Although most of them had actually thrown away their Novice Staff, the teacher and 13 other students had held onto their weapon. After that, when an Enhancer joined the fleet, he told them about the benefits of enhancements.
