Double World Obscenity

Our world and the other world "Netherworld" are blocked by the "Boundary Sea" and the boundary sea spreads to the end of heaven and earth. The sky and the sea merged into a chaotic blue, and there was no trace of the shoreline as far as the eye could see. And Youxu is a "place that will forever fall into the netherworld." "There is no sunlight there, only a gray cloud as thick as ink rolls across the sky."
