Fire and Water
Behind a rushing waterfall in a particular location of the Celestial Realm, there was a hidden space where an Ancient Pedestal stood, gloriously holding up a vibrant blue crystal that held the Inheritance of the Disciple of Water.
Near this pedestal, there was a barely discernible floating Spiritual World where few creatures came out of every so often, learning the inheritance before they went back into the paradisiacal world. Most of them rushed to the floating continent on the North of the Spiritual World, this continent being divided in half by a thin line that had fiery environments on one side and a watery environment on the other.
The beings rushed to the side where the particles of the Law of Water were abundant before beginning their cultivation, the continental floating landmass being so wide that they didn't even near a particular position where an explosion of blue and red lights was beginning.
