The Gu Yuan Tribe required vast amounts of casting material mine veins. Although these allied tribes may be weak, they are numerous. Most of them have been established for hundreds to thousands of years and have already completely explored their surrounding areas.
Combined, they have investigated almost all parts of the vast Wilderness of the Gu Yuan Tribe. Almost at the same moment that they received the imperial command from the Gu Yuan Tribe, these allied battle divisions began to take action.
Of course, top-grade mine veins aren't as common as stones in the wilderness. Only a few tribes find them. However, there are about sixteen hundred lower-grade battle divisions under the Gu Yuan Tribe, as vassals. Even if only a tenth or a hundredth collaborate, there could be dozens of mine veins, enough to satisfy the demand for casting materials from the Gu Yuan Tribe.
Hum, hum, hum!
