The campus was very empty.
Due to the Fest of Lower Elements, the majority of the students, obediently following their teachers' instructions, remained in their dormitories. The few who dared to stroll through the corridors wore bright red arm covers—temporary signs of the student union patrol team. As the overweight student put it, the red arm covers were the professors' 'Hawk Dogs'.
Facing the patrolling figures back and forth, Zheng Qing hesitated for a few seconds, and then decisively pulled out an invisibility talisman from his pocket and slapped it on himself. This standard talisman could perfectly hide the presence of a wizard, such as their figure, scent, body temperature and so forth, for almost fifteen minutes. With just a pair of naked eyes, it was hard for the members of the patrol team to spot Zheng Qing.
