Chapter 685: Chapter 685: My Grandfather knows who my biological father is? 1

When Shi Beiyu said this, Mu Siyin’s face was filled with shock, not to mention Old Master Lu and the others.

What did he mean?

Could it be that her grandfather... knew who her biological father was? !

Mu Siyin stared at Old Master Lu in shock.

Old Master Lu froze for a moment before he forced out a laugh. “Your marriage to yinyin is a joyous occasion, so don’t mention the past. Besides, I really don’t know who yinyin’s biological father is.”

As soon as he said this, old master shi snorted, “It’s not a glorious matter. Why are you calling him? !”

Shi Beiyu’s mother also disapproved, “Ah Yu, without a biological father, there would be no biological father. Why do you have to find him? I’ve been in trouble.”

Mu Siyin and the Lu family were already troublesome enough. If another biological father appeared, wouldn’t they be annoyed to death? !
