After the cultivators from the Dark World left, the other cultivators that were around also left.
Many people were awed. Ziwei Imperial Palace currently had a battle prowess just as strong as the Emperor's. At least, it was so for the top stratum. Of course, when compared with the whole of the Dark World, the gap was still rather wide. There were still many other powerful figures in the Dark World, and they had made progress in the relics, like the Ancient God Clan from the Divine Prefecture.
If the Dark Lord commanded all the forces in the Dark World to assemble and attack Ziwei Imperial Palace together, Ziwei Imperial Palace might not withstand the battle.
But yet again, the cultivators in Ziwei Imperial Palace had made tremendous progress in a short amount of time. If given a bit more time, how much further would they have improved?
Once Ye Futian entered the Imperial Realm and became an Emperor, the world would have gained her eighth super power.
