Gojo turned around, summoning a black gate that silently roiled like boiling smoke. Unlike Arad, who leaves a tiny black sphere whenever he teleports inside his stomach, Gojo uses magic and leaves stable gates.
Arad had just been learning to create those gates for his maids to use, but even now, he is nowhere near as skilled as Gojo is with them.
Arad knew that Gojo still far surpassed him in the potency of their magic. At this point, Gojo is a Mature Adult dragon, just one stage above Arad. But even with that, Arad still felt that Gojo was somewhat even stronger than that; his presence felt as heavy as that of an old, if not an ancient, void dragon.
That was both bad and weird. It is bad because, unlike Arad, who is an immortal Pricolici, Gojo is flying through his lifespan like an arrow through the air.
