Why were Heaven and Earth allowing their invaders to roam freely inside the sky? Why did the privileged cultivator stop chasing Noah and the others as soon as they retreated too much?
Those and many more questions often appeared in the experts' minds as they continued their clumsy exploration of the sky. Everyone had different theories, but the most valid explanation came from Heaven and Earth's dormant state.
The rulers had planned countermeasures for an eventual invasion, but Noah and the others didn't know if they were flexible or fixed programs that would activate after triggering specific conditions. The current situation hinted at the latter, but answers were impossible to obtain when the sky was involved.
Nevertheless, the group did their best to exploit that apparent flaw that Heaven and Earth had left in their defenses. They crawled, escaped, and crawled again, but the environment never seemed to change.
