While the average cultivator was going through a crisis of decisions, the top echelon finally arrived in their airships. They had already sent people ahead of time to observe the location and find any suspicious points, and what they reported back had them trembling till now.
If what their men said was true, then the Pan Suppression Sect's name would come true in but a few years! Heck, by the time people of their stature are done with one closed-door cultivation session, they might come out and find that they had new suzerains.
Their problem with this was not that the Pan Suppression Sect may harm them or might change the way of life of the people. In fact, given what Darius had done on Fallon, one could infer that he was like Prometheus, coming to bring the Neanderthals fire to upgrade their lives.
