Su Yu stopped before the door and touched the doorknob. His pupils turned red and saw that there is no evil qi around. This means that there should be no danger behind this door. No evil ghost or whatnot. He made a pause. Did the evil ghost leave? He thought. Earlier the evil qi in the hall was so thick because it was covering all the walls just to deceive their eyes. Then there is the front door closing.
The evil ghost must have been present earlier. But, it was clear right now that it is not here. So, this door before them should be safe… well, precisely the entire hallway. Even though he doesn't know why did the evil ghost leave, but since they are currently safe, then he will grab the opportunity to interact with his audience.
