Three days later.
Cyan Stone Demon Cave.
This is a massive Demon City.
The entire city is tightly shrouded by an endless Demon Cloud, which is not an ordinary mist, but the condensate of the resentment of billions of vengeful spirits. It appears in a heart-stopping deep purple and inky black, with occasional dark red lightning cracking within the depths of the cloud, like the blood-colored eyes of a demon. The Demon Cloud is constantly rolling, with a greedy desire to devour all light hidden in its flowing traces.
The city walls are built with the bones of millions of giant beasts mixed with obsidian, towering thousands of feet high, resembling ferocious fangs rising from the depths of the earth.
The walls are not smooth, but are covered with densely packed, twisted dark runes that seem alive, constantly wriggling and deforming, sometimes stretching into eerie incantations, sometimes curling into faces of pain-stricken ghosts.
