Dark Lightning

Ulthane's mind was completely blank, utterly dumbfounded.

When he secretly observed Roy using Fusion earlier, he felt that it was very amazing, but he did not take it seriously because he thought that this demon named Osiris was just trying to think of a way to fuse with one of his clones. Although it seemed like Demon Osiris's strength had improved after fusing, this increase did not attract much of Ulthane's attention.

However, how could he have thought that it was because Roy's Fusion failed the first two times…

After Roy completed the Fusion for the third time and truly successfully fused, the sudden increase in power stunned Ulthane! It was not until this moment that Ulthane finally understood that this mysterious ability of Demon Osiris could actually achieve such an astonishing effect!

This was a freaking godly skill!
