Tan Lu Yuan could only respond with a bitter smile: "Yes, you're right, in this regard, I'm not as good as him."
Of course, he couldn't help but have some complaints in his heart. If the circumstances were switched, even if Qiao Yu was his student, he could be more open-minded than Tian Yan Zhen.
Alright, hearing this, Elder Yuan felt it was about enough. He didn't want to say anything more and was just about to rest when his phone vibrated several times.
Yuan Zhengxin picked up the phone and saw several messages from Qiao Yu pop up.
He clicked in and saw a photo, a manuscript with very neat handwriting.
However, the old man wasn't in a hurry to look at the contents of the manuscript in the photo but first looked at the string of words that followed.
"Grandpa, are you asleep? Sorry to disturb you. If you're asleep, you can reply tomorrow. The picture I just sent is a conjecture my mom made after reading my paper on the upper bound of rational points on curves."
