"That's a feasible plan, very tempting too. Still, there are a few impossibilities of that happening..." Zeras mused to himself as he thought well about it. Firstly, was the fact of him going to the upper realm, the System wanted that as it saw that as the only way for Zeras to grow stronger quickly. As for what reason it needed him to grow stronger, He isn't aware of, but judging from the myriad of abilities of the Chaos Devourer. He didn't really think anyone needed to tell him the reason why he needed to grow stronger.
The reason why Zeras himself wanted to go to the upper realm, was to hopefully find his clan, something whose information is still in the hands of the Celestria Family patriarch, Jason Celestria.
Without obtaining that knowledge, Zeras can't go anywhere.
