Wei Cheng put away the Alien Demons Catalogue without any expression on his face, but his heart was far from calm.
Firstly, he was prepared for the backlash when he used the Alien Demons Catalogue this time.
After all, Chu Xianren also said that to face these thirteen types of Alien Demons, it would be best to prepare thirteen Self-Defilement Methods.
But up to now, he'd not found even one Self-Defilement Method.
However, after using it this time, he did indeed feel a powerful infiltrating impact, but it was all suppressed by his spiritual domain, and ultimately did not result in a backlash.
This also proved that within the range of simple sensibility, if he just remotely scouts, his Power of the Primordial Spirit can withstand the contamination of Demon King level at most.
Of course, anything above the Demon Lord level is definitely untenable.
