Kami's Growth Story in Another World

This is the first time a new writer is writing a novel, so please be gentle. The story originates from a continent called Hikalip. On that continent, the demons and other races formed a crusade alliance and fought for more than 1,000 years. Only then did the tribes push the demons back to the land of purgatory lava. At this time, the tribes were already crumbling and the continent fell apart. The gods could not bear to use their divine power to repair the continent and save the tribes, so that the tribes could continue to pass on. The demons would one day come back, and what would the tribes do then?
