It wasn't hard to guess that the guy had Fire Element Affinity. After all, not only was he here in this place, he also wanted the Molten Divine Rock Flowers. What Rean and Roan were surprised by was the fact that they quickly felt the power of space contracting around them. 'Void Tempering Realm!'
However, that restriction in their bodies wasn't anything impressive as they could still move. One of the reasons was that the twins' cultivation wasn't that far away from the Void Tempering Realm. Second, they were much stronger than any common Elemental Transformation Realm cultivator. Last but not least, their enemy was only in the Initial Stage of the Void Tempering Realm. His control of the spatial powers was very limited.
In addition to Fire Element, Wind Element followed suit, increasing the enemy's power even more. At this level, it wasn't anything surprising that cultivators could use two elements with great proficiency.
