The old rulers agreed to take care of the challenging mission, but Noah knew that they wouldn't depart right away. Such a unique task required a long period of study, even when it came to beings that represented the original version of Heaven and Earth.
The mission would involve a deep understanding of the current state of the world and expertise in different abilities, and the right mindset. Destruction was nowhere near simple to spread, and Noah knew that far too well.
The lack of proper tasks or missions for Noah's group forced them to remain inside the city. Their existences could accept the many magnificent buildings and their functions more easily after defeating the ghosts. They felt like a reward for their efforts, so their laws didn't cause any problem when they settle inside specific structures to continue their training.
