In this short scene, Ren and Zhuang discuss the situation at the entrance to the laboratory. They find that the exit door has been opened, and two people are in the way, infected by the undead. Ren thinks that the two people must be maintenance staff, but he doesn't know why they opened the door in the first place. Ren tries to kill one of the undead, but the other is too fat to stab. Ren wonders if it is a new mutation in the zombie, or if the undead have been finished. He stabs the undead in the heart, thinking that the undead's heart is on the wrong side of its body
