Yuan Zhengxin carefully browsed through the questions raised by Qiao Yu and the responses from Pan Jingyuan. When he looked up at his professor, he noticed that Professor Pan's eyes were very dark today.
Unable to help himself, he smiled slightly and said, "Little Pan, you've worked hard."
Pan Jingyuan gave a bitter smile and said, "Elder Yuan, it really has been tough. I feel I wasn't even this tired when I was doing my own projects. This kid's questions are so tricky that I have to think carefully at night before answering them, and he keeps sending more questions. I think if I don't respond, it might dampen his enthusiasm..."
As he was speaking, his phone started vibrating again, and Pan Jingyuan instinctively picked it up for a look, then immediately grumbled, "Oh boy, here we go again."
He handed the phone over to the elder for him to take a look.
