Xu Shan didn't follow Yunxi deeper into the clan. He let her go ahead. However, he did keep his eyes on her using his Divine Consciousness.
His Divine Consciousness shrouded the entire Clan Premises. He was able to see everything, from the hidden rooms where people were getting intimate while getting worried about getting caught to the places where shady deals were taking place by corrupt elders.
He had more or less understood the entire structure of this clan. The clan was quite poor. Even though it had a few treasures, but they weren't significant.
Their clan was going downhill, which was quite surprising considering the fact that one of their in-laws was the father of the Divine Queen.
Not only did they not have much wealth, but their security was also quite pathetic, as if they knew that they didn't have anything worth robbing left anymore.
