In short…
After running around in circles, it seemed he hadn't really learned anything new?
Thinking about it, he had heard about Hu Da Li's situation, but other than knowing that he was in trouble thanks to the Deathless Sect and presumably Lady Hua, which was something he had already guessed over five years ago, he hadn't learned much.
For Fu Hao Xin and Ke YiQing, he knew that they weren't in the Academy and had gone on their own respective paths, and he had even found out that Fu Hao Xin was likely on a bit of a… search for personal truth, to put it politely, but he still didn't know where they were.
And for Tian Li and Ba Hu, all he knew was that they had left before he had met him!
As for Mu Di Bai… There was no need to even mention Mu Di Bai!
Although he was one step closer in each direction, the amount he had actually learned seemed to be quite little.
