Wang Yu was the most familiar with the kind of people that were in Quan Zhen Sect.
These fellas had always had this belief that the enemies of their enemies could be their comrade-in-arms. As long as they had a common enemy, even if they were strangers, they could pull them to their side to work with them.
Evidently, the other party was well aware of the way the Quan Zhen Sect operated. In fact, they seemed to be extremely fearful of how these fellas could pull others in to work with them.
In Salat City, the Mystery Pavilion could be considered a large and independent guild. If there were no conflicting interests, they would never bother meddling with the affairs of a small guild like the Thousand Waves Palace.
Even so, the other party was still adamant about trapping Mystery Observer here. This proved how much of a fear the Quan Zhen Sect had instilled in them previously.
