Gu Xia nodded and then turned to open the door.
Cheng Xiao saw her come out and fiercely took his last drag before asking her, "How did it go? Any clues?"
"She went to the Fourth Hospital the day before yesterday, and... had a chest examination."
Cheng Xiao slapped his thigh, "I knew it! All these victims had been to the Fourth Hospital and had that examination. It must be Guo Shujun."
"I don't think it's Guo Shujun."
"Why?" Cheng Xiao was taken aback.
"Go check now. When Han Mingshi was attacked, Guo Shujun should have still been in the Fourth Hospital without having come out. He should have an alibi."
"Are you that certain?"
Cheng Xiao didn't understand why Gu Xia was so sure it wasn't Guo Shujun.
"Yeah, ninety-nine percent certain."
Cheng Xiao called his subordinates in front of Gu Xia and ordered them to immediately investigate at the Fourth Hospital.
