491 Us, North Sea

Cloud Castle was concealed by thick layers of cloud. The deep clouds were not only used as a cover, but also provided an outstanding defense.

The 32-kilometer-long North Sea Wall was the final defensive line against the Blood of God, but now, fragmentary nicks had already appeared on its surface.

Each castle possessed countless cloud mirrors, through which one could clearly observe the situation outside. Above the mirrors, densely crowded enemies rushed over from all directions.

What followed the blood elementalists was a concentrated azure arrow rain which would occasionally strike them.

The water elemental arrows that missed would explode into balls of cold, bone-piercing ice shards.
