Inside the Dimensional Realm, Zutuk was able to feel the much higher concentration of Divine Energy, which truly excited him. "This is so good..." The Dimensional Realm always has several times more Divine Energy than the outside world, thanks to Celis, so it was obviously much better. Of course, it couldn't compare to the usage of Divine Stones directly.
Celis was quite happy to have a sentient Demon Beast inside since all Demon BEasts so far were still below the Transition Realm. That meant he didn't need to organize the Red Luan's race and simply gave Zutuk an explanation of how things worked.
