In the Desolate Wilds, there were warriors who sought Mine Veins, but these sects were too numerous and diverse. Moreover, they jealously guarded their secrets and were unwilling to share with outsiders, so they never really achieved great prominence.
Each tribe had its own vein exploration lineage, and the Gu Yuan Tribe had theirs as well, though it hadn't formed into a formal lineage. After years of continual exploration, the vein explorers of the tribe had finally mastered their skill, which was indeed a cause for celebration.
"Over the years, our Gu Yuan Tribe's development to its current state owes much to the various temple lords, tribal elders, and numerous War Soldiers. Rewards will be given to everyone whether they are vein explorers or other warriors."
