I'm curious as to how that secret organization/sect hadn't already conquered the whole world, seeing how powerful they seem to be. Based on all we know so far, they should have more than enough to wipe the whole world out a dozen times over, and should've already finished it long before our MC showed up, so why haven't they? Why do all these villain sects bent on world domination and/or destruction always keep on waiting, never actually going for it? Because apparently, if you wait long enough, you will end up getting wiped out. So, I don't know, maybe don't wait that long and instead move along with the plan?
