By then, perhaps Xu Dongcheng's daughter, Xu Meijia, may be at her breaking point.
The fifth day.
Principal Xu Dongcheng visited Ding Yue's room early in the morning.
"Principal Ding, let's go back to our country. We can still look for other international agencies that are doing research in biomaterials," he suggested.
Principal Xu Dongcheng's complexion seemed more and more haggard.
Ding Yue sighed, remarking, "After five days, we still haven't heard from Professor Yang. It seems our hopes are dwindling. If this continues, we might have to work on biomaterials on our own after we return."
At this very moment, Wen Ruohan also arrived. After hearing their conversation, he asked, "Principal Ding, shall I book our flights now?"
"Hmm."
Ding Yue nodded.
However!
Just as Ding Yue nodded, his cell phone rang.
It was Professor Yang Kaining calling.
