After leaving the Demonstration Arena, Chen Nan did not return to his room but wandered around the Purple Cloud Palace.
He was well aware that the Purple Cloud Palace would not easily let Yu Wenqingxue go, so he needed to make plans early. If they refused to release her or discovered his identity, he had to find a way to rescue Yu Wenqingxue and fight his way out of the Purple Cloud Palace.
Now, as he walked around, he wasn't just aimlessly wandering but familiarizing himself with the surroundings.
As the art of war states, knowing oneself and one's enemy ensures victory in a hundred battles. Familiarizing himself with the defense layout of the Purple Cloud Palace and the terrain would be a great advantage.
Chen Nan spent three hours (which is six hours), touring the entire Purple Cloud Palace.
