Jiang Che traveled west along Cangyun Mountain.
After traveling for about half a day, a sprawling range of black mountains loomed before him.
This was the Black Stone Mining Area, one of the Cangyun Sect's five major mining areas.
The mining area wasn't large, but the resources it produced were quite precious.
It primarily produced two types of precious ores: Profound Iron Ore and Snow Crystal Jade.
From Profound Iron Ore, one could refine Profound Iron.
This was a metal even more precious than Secret Iron.
It was not only extremely hard but also highly resilient.
Furthermore, it was excellent for storing Strength.
Therefore, it had always been a prime material for forging divine weapons.
Snow Crystal Jade, on the other hand, constantly emitted a type of "aura" that aided in the cultivation of Qi Blood.
This made it a vital material for constructing Cultivation Rooms.
In addition, other rare, associated minerals could occasionally be unearthed here.
