Leon was left speechless. The system's creator was saying that he wanted to go to another universe… as if he was just going to buy something at the nearest convenience store. Leon, Ilyana, and Tyrselle have considered that may exist other universes, but they had no idea how to leave the current one. Rather, they had no interest in doing it. There was a chance that they don't exist in other universes. If what the system's creator was right, maybe things out there were so different that they wouldn't find any purpose in those places.
"Perfect, now that you are leaving, you just have to manipulate time and cancel all the effects of your actions," Leon said. "As you said, you learned many things thanks to us. So, at the very least, you have to return our old lives."
"That isn't possible. To do that, not only will I have to sacrifice a lot of mana, but I also will have to sacrifice a massive part of my powers. Without the strength I have right now, I can't move to the next universe."
