Zuo Qiu knocked on the office door that afternoon. He had a document in a leather file held in his hands. "Master Yan, the laboratory had this sent over."
Yan Beicheng nodded as he took the file. Zuo Qiu left the office.
After he closed the door, Yan Beicheng took the report out from the file.
The report was for Lin Chu and Dai Huimin. It was not difficult to get a sample off Dai Huimin.
When Huang Changxian had previously reported to him that Dai Huimin had brought Lin Chu's to the orphanage on her birth date, Yan Beicheng had given Huang Changxian instructions to get ahold of Dai Huimin's hair, or anything similar that will be of use.
As for Lin Chu, he could just get samples from her pillow.
