The Xu family had long fallen asleep. When they heard the knock on the door, a servant picked up a stick asked loudly behind the door, "Who is it?"
So cold that he couldn't speak properly, Xu Shoutu shouted while trembling, "I'm your young master! Open the door for me quickly!"
The servant opened the door a crack and saw his young master covered in a blanket. He exclaimed and hurriedly opened the door. "Young Master, why did you come back overnight?"
Everyone in the Xu family immediately moved and pulled him in. They quickly fetched him a heater, hot water, and soup. Even the guards were arranged to rest on the other side.
Xu Shi also put on his clothes and got up. When he saw his eldest grandson rush back overnight, he asked with a frown, "Has Xingzhou Prefecture fallen?"
