Wandering around the Academy, Di Tou took some paths he wasn't so familiar with, while generally heading in the direction of the student or 'Academy' part of the Academy. Over the course of five years, although the Academy hadn't changed as drasticly as it had in the thirty year gap Di Tou had taken, quite a lot had still changed.
New shops, new people, new places to see! All in all, the Academy was constantly bettering itself, if it didn't, how else could it lay claim to being the holy land of cultivation?
Still, although things were different, the baseline didn't change. It could just be said to be the gradual shifting of generations that would repeat the same process, not some sort of overhaul.
