The black market is located within Jiguang City, and though nominally a black market, to a great extent, it is more akin to a market tailored for practitioners in the Rule Integration Realm.
The resources required for the Rule Integration Realm are not abundantly produced within the human race's territory, thus, even slightly rarer spirit materials are not available for purchase in regular shops.
This black market in Jiguang City is the place where those in the Rule Integration Realm exchange resources with each other.
The only thing is that formations here shield one's aura and appearance, making it impossible to clearly sense someone's exact Cultivation Realm.
What to sell in such a market requires careful consideration.
If someone brought goods obtained through betraying the human race, trading them here would be akin to seeking death.
