The Power of Positive Feedback

"That'll be 120 low-grade or 12 intermediate-grade spirit stones." Lin Mo with his usual business smile rang up the customer's items.

"Thank you, Shopkeeper. Your exchange is still baffling but I'm glad your items have become cheaper. I can now buy more of these."

The customer, who was a disciple from the Azure Gale Sect happily handed over the spirit stones as his eyes sparkled, lifting a box of Spirit-Infused Potato Chips that contained 24 60-gram packs. After the price adjustment, it went down from 2 Spirit Stones (Unspecified Quality) to 5 low-grade Spirit Stones.

Lin Mo tried to understand the reasoning for that price but since he had no idea about the actual economic state of this region of the Realm of Nine Heavens, he gave up and asked the system for an explanation instead.
