Lyla happily held onto Little Black as they began to run around the village, even going to villages all around the large city. In the end, in order to carry the hundreds of kids, Little Black had to use his crystal will to carry a huge platform behind him in addition to it taking practically the entire day.
However, while they did this, Dyon was meditating. He had never done something on this scale before, and his aurora had only just reached the Lower Essence Stage. If he wanted a home large enough to house hundreds of kids, it would take quite a bit out of him.
The concept of using arrays to form tangible objects is something only those at the Lower Essence stage of their aurora could accomplish. Although Dyon's weapon's hell array could feign this if he incorporated his crystal will to them, the truth was they were still just pockets of energy at their core. To substantiate something real from something practically free flowing and illusory, required a potent amount of power.
