After a while, Yue Xin came out with Prison Guard No. 12.
When Su Yu found out that Yue Xin was the only criminal who had talked to him and asked him how much his salary was when he opened the door that day, he felt that, logically speaking, people who could enter Building 1 would not care about such questions. Therefore, when Su Yu found out that someone had broken the ritual of murder, he eliminated Yue Xin first. In the end, the truth was often the most unexpected. It seemed that there were some things that could not be answered correctly just by thinking about logic.
Yue Xin's current route was obviously back to Building 1. Su Yu followed behind her with his men. He had been observing Yue Xin's walking posture and the state of her muscles and realized that she was not vigilant about her surroundings at all. She was clearly an ordinary person. She looked casual, but she was actually on guard. Yue Xin had flaws in every aspect.
