Making his way through the valley nestled between a few of the large mountains of the mist covered mountain range, Xuan Hao searched through the entire valley within only a few days. Having first made sure that there weren't any powerful demon beasts around before sweeping through the entire place with his divine sense later.
Although he did not end up finding the Three Celestial Gates that he was looking for, he still managed to find out more about the mountain range from searching through the entire valley. The most shocking being that the demon beasts inside the mountain range were far weaker than the ones hiding inside the mist surrounding the mountain range.
From what he knew about mountain ranges with demon beasts present in them, the strongest demon beasts would always reside at the center of the mountain range where the qi would be thicker, and the spiritual herbs would be more abundant.
