Qin Yu nodded to show he understood, then stood up decisively, "You guys go ahead and eat, I still have some things to take care of."
Liu Tian asked with a curious face, "Brother Yu, where are you going? It's only 7:30 now, and there's still half an hour until the preliminary competition."
"Of course I'm going to check out every exhibition hall! Didn't you hear what Old Zhou said? During the preliminaries, the organizing committee will randomly designate a few exhibition halls and select three pieces of stone from those halls. So, I have to familiarize myself with the materials in the other halls."
Qin Yu patiently explained.
"Brother Yu, cramming at the last minute won't help, with only half an hour, how many halls can you actually see?"
Liu Tian scoffed, believing Qin Yu was engaging in a futile effort.
"Half an hour is enough for me to finish looking through all the halls."
