Revalor frowned at the bizarre sight in front of him. At least a thousand meters of the area was covered by the shadow, and he could not see it through. It was as if a big chunk of that area had disappeared into the void. The most bizarre thing was the fact that the shadow area reached the sky like a pitch-black tower. He knew it must be Lu An's skill, but he did not like this skill because he could not observe Lu An. He did not know what happened inside that space, whether Lu An was winning or losing.
The former Elven King was helpless, but at the same time, he was surprised that Lu An could pull up such a trick. He never saw the ability like this; even no demon he had encountered so far had the same ability.
