He didn't know what kind of ultimate technique this Mountain God Roar was. He had never heard of the name before, and today was the first time he heard of it. How could he know how powerful it was?
However, with the second brother of the Black Mountain Crow Brothers shouting so loudly, he understood just how powerful the Mountain God Roar was.
This was not an ordinary kind of power.
The Mountain God Roar attacked the soul specifically.
When shouted, it was like a thunderclap on a sunny day, directly targeting the soul. If one's cultivation of the divine soul wasn't strong enough, being shouted at like this would certainly stun them on the spot. In severe cases, the soul would be injured directly. This was similar to the effect of the Dazzling Mind Bell, but the Mountain God Roar was much more powerful.
The Dazzling Mind Bell was an inferior product, so its power had limitations.
What about the Mountain God Roar?
