A Powerful Warning

Within the heavenly planes, the demon race was a particularly invasive race. Moreover, the assimilation capabilities of their bloodline was extremely strong. An ordinary race would be hard-pressed to avoid being turned into a demon once the demon race's bloodline assimilated with theirs. Therefore, from their bones down to the very blood coursing through their veins, the demon race could be said to be an extraordinarily invasive race. With their aggressiveness, they would not only take over a power's territory and land, but also invade people's bloodlines and souls, completely converting them into a denizen of the demon race. This was the major factor behind how the demon race had grown into a large tribe renowned around the world.
