The six fixed-price areas, the prices of the stones are arranged in a trapezoidal pattern.
The lowest-grade stones require only one thousand Spirit Stones each, and one Spirit Stone can provide a regular mortal with enough to eat for a month. Although a thousand Spirit Stones is not cheap, it's not a big deal for someone in the Golden Core Realm. In the next five districts, the price doubles — two thousand Spirit Stones for the second district, four thousand for the third, and so on. The most expensive, the sixth district, costs thirty-two thousand Spirit Stones per stone.
These prices are indeed not cheap, even for someone in the Golden Core Realm, it's not a small amount to casually spend.
