Ye Feng directly arrived at the cave mansion on the Chief Mountain and modified the defensive array of the cave mansion. He took out a bright red crystal, and as soon as the bright red crystal appeared, the entire cave mansion increased in temperature.
The warmth was gentle, making people feel comfortable, yet without feeling unbearably hot.
The bright red crystal was none other than the Skyfire Divine Crystal that Ye Feng obtained after slaying the Skyfire Elf King in the Skyfire Secret Realm. Seeing such a large piece of Skyfire Divine Crystal, a smile appeared at the corner of Ye Feng's mouth.
With this piece of Skyfire Divine Crystal, Ye Feng could easily eliminate all the negative energy within himself.
Furthermore, this Skyfire Divine Crystal could help Ye Feng accumulate the energy needed for a breakthrough. Once Ye Feng eliminated all the negative energy within him, he could elevate his cultivation to the mid-stage of the True God Realm.
