My uncle crossed his fingers and spoke in a deep voice, and he looked at me seriously. "Nanxing, I wasn't at home at that time. I didn't witness the scene with my own eyes. I can't jump to conclusions, but I won't hide anything from you. Big Brother has always been coveting your blood. He wanted to use the Tong Family's resource to set up a research team specifically to study your blood. It would bring the Tong Family endless wealth. He suggested your parents to give birth to another child after they surrendered you to the Tong Family. Before you, there were no children with a foreign surname who has inherited the family's unique bloodline."
There was a deep sense of guilt in my uncle's voice. "In the beginning, Big Sister and sister-in-law did their best to help the Tong Family earn money so that they would let you go. However, after noticing Big Brother's attitude, they started to gather leverage so that they could negotiate with him. The situation got worse and worse."
