After the black dragon's mephistophelean mirth, a ridiculously gigantic black magic circle, estimated to be at least five kilometers in diameter, manifests a kilometer above the surface, with the dragon of the same hue at its center.
It's the largest magic circle I have ever seen in my whole life. Given how much mana this dragon has, it's no wonder it is capable of casting a magic circle that size.
But the size is not what is unsettling me. The nature and the formation of this magic circle are something I have never seen before. In short, the spell after the circle is still unknown.
"LEVEL 9 BLACK PARADE."
The dragon's voice is loud and clear, and each of its words is full of conviction. It recited the name of the spell that I had heard about a long time ago but never seen being performed.
