Chapter 872: Old Man

This Essence Energy Art was also strange. There weren't many changes. It was purely an Energy Refinement technique.

With every circulation of the Essence Energy Art, a portion of the impurities in the Essence Energy would be removed, allowing the Essence Energy to become purer. It was as though it was a technique that specialized in extracting Essence Energy.

Zhou Wen originally imagined that by cultivating this Essence Energy Art, he could enter the Founding Emperor Tomb, but he realized that it was useless. After he gained basic mastery of the Essence Energy Art, Zhou Wen used it to push open the door, but the door remained firmly locked. It didn't open.

Zhou Wen was somewhat disappointed that he couldn't enter the Founding Emperor Tomb in-game.

He originally wanted to try entering the palace in-game to see if there was a way to pass through the temple guarded by the stone sword, but now, he had to give up.
