Chi Xue and the others were, after all, at a higher cultivation level than the Nine Nether Nether Soldiers and Demon Soldiers.

Once the Lord of the Universe appeared and attacked, it would mean the final battle had begun. Only techniques unleashed by Chi Xue and the others at their peak could cause him the greatest trouble.

Chi Xue and the others would surely be
