Luo Xiao did not display any fear on his face, instead, he looked at the demon with great curiosity. He had read books about the demon race before, and what he had understood was that they had two shapes. One was their human shape that was almost impossible to differentiate from normal humans, the other was their demon shape.
The demon shape varied from demon to demon, some were more human while others were more beastly.
It was in general very rare for a demon to display their demon shape unless they had encountered an opponent they could not handle otherwise.
Even the soul cultivators had their strength enhanced when in demon shape, and now that this man had transformed his soul power was roiling around him, so powerful that yellow energy with golden streaks was impossible to get close to him.
