The Mysterious Heaven Sect was near the Western Wastes, but even so, it would take the flying boat about ten months of full-speed flight to make one trip there. This was also why, after the other party had purchased a large quantity of goods two years ago, the second transaction was spaced so long apart.
The Western Wastes were vast but also impoverished, the Moon-Watching Sect could throw its weight around in this area, but it was not easy to amass a large number of spirit stones. A Son of Heavenly Way had already scavenged quite a lot, and after that, earning spirit stones didn't come easily. As for trying to rob Golden Core cultivators...let's put it this way, if that route were truly viable, Bu Shixian wouldn't be so destitute, to the point of being desperate enough to trade feathers for spirit stones.
