The director walked forward and knocked on the courtyard door. "Mr. Fu, are you at home?"
"Yes, come in." An old and hoarse male voice came from the small courtyard.
"Come, Professor Xia, this way please." The director opened the door and brought Xia Wanyuan in. "Mr. Fu is already 90 years old and is the oldest person in our research institute. If he doesn't know about it, there's really nothing we can do."
"Thank you." Xia Wanyuan nodded slightly at the director.
The door opened and a white-haired old man sat in the living room. The director bowed to the old man. "Old Sir, this is Professor Xia from Qing University. She has something to ask you."
Xia Wanyuan bowed slightly to the old gentleman to show her respect. When she looked up and met the old gentleman's gaze, Xia Wanyuan realized that Old Master Fu was actually looking at her with a very strange expression.
"Director, if you have something on, go ahead. I can do it myself."
