Agreed with Orm.
Whether or not you agree with his approach, Nameless's power is one built off the backs of Ages long past. Our opposition to the Fates has become more than just a tool to save our lives; it has become a philosophical disagreement with their entire approach. From the Diagram to the Cultivators, we have seen how the Fates love to design flawed systems and to subsequently destroy them and people of such a system for being "flawed." Moreover, they have done this for countless eons, dozens or even hundreds of Ages discarded in the dirt, all evidence of their existence wiped out.
With all these Ages, it is impossible to simply say that each Age is stronger than the last. Rather, given the monikers of Age of Truth and Age of Might, each Age had a theme, a field where it shined above all others, and it is no less than our duty to exploit these strengths. Zang Kong is no archaeologist--he will know nothing of the powers Fate has so desperately tried to erase. If Scientific Cultivation is the exploitation of hundreds of Ages of interactions despite knowing nearly nothing about such Ages, how much more potent could we be if we went directly to the source and added the strengths of these Ages to ours? We could be better at Scientific Cultivation than Zong Kang was.
EDIT: If anyone else is interested in the trade Embar just conducted, I'm also open.
