Quite a thought, but bear with me, in the begining, Yang Qi was not able to cultivate further, because the qi in both the mortal and inmortal world was not enough, then it comes a random guy called proud heaven with other part of the Divine Legion Seal, and he has been able to succesfuly cultivate. Knowing that in the future world there is no godly plane. It tickles me quite a bunch.
Also i remember reading that Proud heaven had like 100 000 000 000 clones, and i still have not read about anyone of them
