Before Leng Yan could speak, Qiao Qing said, "Wait a moment."
Zhou Xin stopped and turned his head, "Ms. Qiao?"
Qiao Qing said, "We need the full set of evidence to get rid of them for good."
Zhou Xin asked, "What do you mean by that?"
Qiao Qing, "A DNA test."
Zhou Xin froze, "For Leng Jie and his father?"
Qiao Qing responded, "A test for Leng Jie and his father, then a test for Leng Jie and Leng Yan. We should do them all."
"B… But where do we find Leng Yan's dad? Plus, how do we get them to do a test without freaking them out?"
Before Qiao Qing answered, Lang Yin had handed over a small box, "Miss, I figured this might be useful so I got them before you ordered me to."
Everyone looked over and saw that there were two strokes of hair inside the box. Each stroke was tied together by an elastic. They were labeled, "Leng Jie, Wang Dazhu."
