"If Mom only uses the blood of the broken arm for a DNA test, she can indeed determine that it's my arm. But if she uses the epidermal cells of those broken arms for a DNA test, the results will definitely have nothing to do with me! She accepted my bone marrow. Her blood is the same as mine, but her DNA in other places is still different from mine!" Qiao Nian explained concisely.
Lu Zhu was also a smart person. He quickly understood what Qiao Nian meant. "If Mom used epidermal cells for a DNA test back then and found out that it was your arm, it means that the person who helped Mom might have tampered with Mom's test sample."
"That's what I think." Qiao Nian's expression was serious as she continued, "If someone really tampered with the sample, it means that that person is related to the person who accepted my bone marrow. He might have been involved in my kidnapping back then."
