Noah and the rest of his group ran away as fast as possible to avoid the destruction behind them. Their senses didn't allow them to inspect the battlefield, but they didn't want to take any risk nonetheless.
The group quickly arrived in areas where the battlefield's light couldn't reach, but they didn't stop. None of them believed that they could hide from Heaven and Earth, so they wanted to put as much distance as possible from the rank 9 existences.
Noah had the beginning of a plan, but he lacked many essential factors. He had a goal, but he couldn't even begin to imagine how to reach it. Still, he didn't discuss the matter with his companions just yet.
The group flew for entire years before deciding to stop in a random spot. King Elbas immediately proceeded to cover the area with defenses, and Noah began to transform both ground and sky to make Heaven and Earth blind there.
