At the center of heaven and earth, within a secret world that has been opened, lies the common stronghold of several great Eternal Sects.
Since the realization of the 'magic' disaster by each Eternal Lord, many preparations were made in advance, such as merging the strongholds of several great Eternal Sects. Only in this way could all powers be united to resist the 'magic' disaster.
The fact has proven that this approach was correct.
If the several great Eternal Sects had not merged in time, when the 'magic disaster' descended, that Demon God would first strike, Source Demons would rampage, and even if the several great Eternal Sects were not completely destroyed, one or two would surely perish.
In the premise that the Eternal Lord cannot intervene, even with many thirteenth-order means of protection, such as thirteenth-order weapons, it would be very difficult for any single Eternal Sect to resist the rampage of the Source Demons.
