The shape of the Endless Sea is the very typical celestial round place, with the sky like a half-spherical dome, enveloping the ocean and the islands above, forming the entire world along with the water currents.
And in the four corners of this sky, there are the realms of four Divines.
The realms connected to each other and with the sky constructed the outermost defense system of this world.
Although this system is still weak, it can at least resist the invasion of those overly powerful entities into the world.
But it can only defend against powerful entities, while the ordinary, weak original inhabitants of the Endless Sea can easily deal with those who can smoothly enter this world.
And the so-called powerful entities are Evil Gods from the New Realm and even other worlds, or various high-ranking existences harboring malice towards other realms.
