Chapter 229 Chapter 19

The door of the utility room in the basement of Building No. 1 was slowly pushed open. Xu Xingliang and a guard stood at the door, looked around, and began to look for the small nail, but they couldn't find it. Xu Xingliang frowned: "Has this room been cleaned today?" Guard: "No, no one has been here! Chief Xu, what's wrong?" Xu Xingliang shook his head, pondered for a long time: "Let's go!" The moment the door was closed, Xu Xingliang pulled the doorknob, turned around to look at the whole room again, and then closed the door and left.
