To be honest, these people had never really paid much attention to a sect like the Paradise Celestial Palace. At best, it was just a minor offshoot that had branched off from their own sect years ago. They didn't even care about the Mysterious Land where the Paradise Celestial Palace was located.
In the eyes of truly powerful sects and families, a Mysterious Land was no big deal. It was simply a place with more abundant Spiritual Qi, and a greater number of Spiritual Objects and Heavenly and Earthly Treasures.
In fact, they hadn't even fully explored the Mysterious Land they inhabited, so how could they find the time or energy to investigate others?
Only major clans and great powers like Profound Island were so insatiably greedy, vainly attempting to unify the world and have all nations pay them tribute.
