To be honest, Qiao Yu found Old Xue's words a bit inexplicable before he left. Of course, he would make it big! It's only a matter of time.
Furthermore, isn't what he's doing considered base operations?
Both his mentor and grandmaster are big shots. Anyone would probably grasp both opportunities firmly, right?
This is how it's taught in moral and legal studies books, so he's just applying things flexibly.
After saying goodbye to Old Xue, Qiao Yu shifted his focus away from these trivial matters and seriously started reading Peter Schultz's second paper.
On one hand, this was where his interest lay; on the other hand, Qiao Yu knew clearly that his ability to bond with these mathematics big shots was because of his insight in mathematics. Not using it would be a waste. More importantly, even though what Professor Zhang said was true, he was still not very convinced.
It was similar to when he was ridiculed on the small house forum; he was determined to solve the problem.
