Actually, the resources of the inner worlds were almost completely controlled by the various sects. After hundreds and thousands of years, one could imagine how much wealth they had.
Most of the great sects of the Inner world had at least one profound-level weapon. Some even had more than one.
Those profound-level weapons were not made by the warriors themselves. Most of them had been exchanged with the Huatian Palace for other items. Those major sects had spiritual stones that they had been collecting for hundreds of years, and they were sufficient to exchange for one or two profound-level weapons from Huatian Palace.
That was also why the major sects in the Inner world had so many immortal cultivator treasures in their hands.
However, warrior sects had worked hard for a hundred years, or even hundreds of years to amass this wealth, only for it to be passed to the Huatian Palace in just a day. In the end, Huatian Palace was the biggest winner.
