The Great Wilderness Calamity

The cultivation world is known as the Four Seas Realm, divided into four continents by the Great Wilderness Ancient Sea. Each continent lies a hundred thousand miles from the next, and only mighty cultivators of the Ascension Realm can cross the distance. At the heart of the ancient sea lies a Dead Sea Vortex that devours spiritual energy. Once every thousand years, a tide of sea demons erupts, its bloodthirsty aura powerful enough to annihilate all living things. The four continents and the ancient sea form a natural balance, and cultivators call this realm the Four Seas Sea-Suppressing Formation.
