The next day, at the noon break, the teaching building was silent enough to hear a pin drop.
Two figures darted across the corridor, silently appearing at the entrance of the infirmary.
Su Junxin placed her finger on the wall, giving it a light tap.
Quickly, a streak of silver electro-light trailed up the wall, shooting straight into the surveillance camera in the corner.
The red light on the camera flickered, then extinguished.
She pulled back her gaze and peeked inside through the thin crack of the infirmary window.
The duty nurse was sitting with her side to the door, engrossed in scrolling through short videos on her phone.
Su Junxin took Li Weize into the stairwell and whispered, "As soon as the nurse leaves, slip into the deepest room on the second floor of the infirmary, where you should wait quietly for me, understood?"
Li Weize nodded, "Be careful, watch out for your safety!"
She flashed him an OK sign, lowered her body and flitted to the other end of the corridor.
