Du Changfeng and the others watched the three Integration Sixth Layer powerhouses, whose cultivation levels were indeed not low. During the initial fight of the Hidden World Seven Heroes, there was only one Integration Sixth Layer present aside from the Wei Family Ancestor, and the highest-ranking Wei family member there was also an Integration Sixth Layer.
To dispatch three at once was remarkable. It would have been expected for Integration Fourth Layers to be sent, as that would befit a top-notch Hidden World Family, whose heads normally possess high cultivation. But Integration Sixth Layer was a different story entirely.
At least within The City, a leading family had never seen someone with such high cultivation, or if they had, it was exceedingly rare.
Clearly, the Wei family had hidden their strength. Everyone knew that even during the fight with the Hidden World Seven Heroes, they were only even, not having shown their true power.
