Lin Yun and Zhang Haoran had breakfast and then headed to the mountain. All the way up, Zhang Haoran exhibited impatience because he wanted to see their ranks as soon as possible.
That was why Lin Yun went up the mountain so early; otherwise, he planned to wander around the mountain base.
At the Martial Arts Convention, the items sold at some stalls were not available elsewhere, and it was rare to find them all in one place. Lin Yun wanted to see if there were any items that would be relatively cheap on Earth but had high value in the Cosmic Trading System.
If he found any, these would be considered local specialties, which would greatly benefit his future business in the Cosmic Trading System.
The best scenario was if these items were sustainable, because then he could continuously sell them in the Cosmic Trading System.
However, finding such specialties was very difficult.
It was tough for something to stand out among countless civilizations.
