The quantity of such spirit stone mines was quite substantial.
There were likely a large number of such spirit stone mines in the North Region.
Finding them wasn't easy; without spiritual veins, there wasn't even a direction to search in.
These spirit stone mines lay deep below the ground. Even if you could dig three feet deep, it was not possible to excavate the entire North Region.
Most cultivators lacked the capability, and those who had the capability neither wanted nor needed to do so.
Hence, after spending some time to completely extract this spirit stone mine, Qin Changqing began his return journey.
The quantity of spirit stones here was considerable. After replenishing the amount the Fairy Stone utilized to overcome the Tribulation Thunder, there was a surplus of about two hundred thousand pieces of spirit stone.
A precise count was difficult since Qin Changqing hadn't yet chiseled the spirit stones; they remained in their original large blocks.
The harvest was good.
