Her parent's death

Xia Jiamu blinked a few times when he saw Xia Meilin enter his study.

"Oh, Xiao Mei, did Ning'er left already?" Xia Jiamu asked. He was playing chest by himself.

"Yes. He still have some meeting to attend." Xia Meilin said as she went to sit on the empty chair that was on his opposite. She took the piece of white horse from D6 and moved it to E8. "Checkmate."

"Hey. I did that." Xia Jiamu huffed.

She chuckled as she rearranged the pieces. "By the way... I have a question to ask you, grandpa."

"Go on my dear."

Xia Meilin paused and looked at him. "Is Yong Biqi my real mother?"

Xia Jiamu's eyes went wide in surprise when he heard the name. He looked around before he walked towards the door and locked it. "Who told you about her?"

Seeing how her grandfather reacted, Xia Meilin already knew the answer.
