All in the Family!
Divine Doctor Lin wasn't about to trust someone so easily, so she pretended to be puzzled and asked, "How do you know your mother's surname was Lin?"
Yuan Jin Xia glanced at Divine Doctor Lin, then shook her head. "I can't tell you that right now. I don't want to drag anyone else into this."
Divine Doctor Lin thought of her sister's daughter, Xiao Xiao. Considering her age, she should be about this old.
Looking at how Yuan Jin Xia bore some resemblance to her sister, she hesitated, then quickly said in earnest, "I once had an older sister. She married into the Xia family. Later, a treacherous villain persecuted her family, and they all died."
Hearing this, Yuan Jin Xia grew excited. She stammered, "I... My grandfather was Xia Ran, and my father was Xia Changqing."
At that, Divine Doctor Lin had no doubts left. She gazed at Yuan Jin Xia with eager curiosity and asked, "Where have you been all these years? Wasn't it said that you got lost?"
Yuan Jin Xia gave her a suspicious look. "Who told you I got lost?"
Divine Doctor Lin hesitated, then patiently explained, "It was Yang Chengwan. He was a close friend of my elder brother, and he happened to know my sister—your mother. They were in love with each other, but fate played a cruel trick on them, and my sister married into the Xia family. So he was a fairly reliable source."
Yuan Jin Xia was baffled. "This is all so confusing, Auntie. Do I have an uncle, too?"
When Divine Doctor Lin heard Yuan Jin Xia mention her uncle, she hurriedly snapped, "Don't bring him up! Back then, he got the news even before Brother Yang, but refused to go warn the Xia family.
