More and more information surfaced with the increase in the number and quality of captives.
Among the captured Aus people, there was a high-ranking official from a mercenary company. Through him, the camp's new owners naturally obtained more information.
The Aus people... more accurately, Hod company, had been operating here for over a decade. Their initial investment in this area wasn't significant until they found the first Vortex Ore.
They didn't make a substantial investment at the start, and they weren't even the first Aus company to "invest" here.
However, after discovering Vortex Stone, they either acquired, squeezed out, or used direct force to expel all competitors.
