Substitute Evil, a unique technique of the Yan Dequan lineage, can be used to replace oneself with something eerie when facing a life-threatening danger.
However, using the Substitute Evil comes with a price. It requires cultivation and isn't something that can be used casually by just capturing any evil entity and treating it as a Substitute Evil.
Using one's own essence as a guide, infuse the evil energy daily without interruption. Only by doing so can the Substitute Evil protect you during crucial moments when your life is at stake.
At this moment, Yan Dequan's face was pale. Activating the Substitute Evil had consumed a considerable amount of his essence, and without a period of recovery, he wouldn't be able to restore it.
Apart from the depletion of his energy, what terrified Yan Dequan even more was Chen Fei's actions.
