Noah had learnt how he had to advance through the divine ranks. Rank 7 cultivators needed to expand their individualities and made them able to affect the laws around them. Their existences had to become complete worlds that could interact with the higher plane.
That belief came from the sum of his clues and understanding. Earth and his experiences in the inscription hall had taught him what a cultivator had to strive for in the divine ranks, but his knowledge about the matter was still vague.
Different ranks usually represented different stages in the cultivation journey. Noah knew that he would be a world at the peak of the divine ranks, but he wasn't aware of the various steps he had to follow to reach that destination.
He could only guess them for the time being. Still, the first step appeared quite obvious now. His individuality had to learn how to take control of the laws around him.
