Qingtu Mountain.
This was a relatively remote area on the Cangyu Main Island, not only seldom visited but also unmarked on any public maps.
On the surface, it appeared to be just a primitive region of tall mountains, dense forests, and rampant Fierce Beasts, but in reality, it was the treasure trove of the Cangyu Islands.
One of the largest Spirit Stone Veins in the Chixue Sea Region was located deep inside the mountains here.
Furthermore, about ten percent of the Spirit Stones produced here annually were Middle grade Spirit Stones.
The output from this Spirit Stone Vein accounted for nearly thirty percent of the Cangyu Islands' annual revenue.
If anything were to happen here, the consequences for the upper echelons of the Cangyu Islands would be exceptionally severe.
