Ye Mo knew that with his talent and learning, half divine was the extreme. Even if he went into solitary cultivation for countless years, he would still be half divine without new enlightenments.
He wanted to vindicate dao so he would have to leave the golden page world and go back to the greater world to experience things. Ye Mo wasn't sad. He was the master of the chaos tree now and his power increased another level. If he wasn't blasted to a million pieces, he wouldn't die with the chaos tree in his dan tian.
When he came out of the golden page world and stood in the divine estate palace again he knew that the only way out of the Mu Hua god mountain was through this mysterious divine estate.
Ye Mo didn't open that yin yang fish tunnel again. He knew that even though with his increased tower, he wouldn't be able to pass that stairway. He would at most go down a few extra steps.
