Load the Taoist System into the Devil

What does it mean that a devil is loaded with the Eastern ghost-removing system? The church couldn't figure it out. I can't figure it out either. The key is that this system is for human use. What do you mean by giving it to the devil? What does it mean that it is not a pure Yang body and cannot activate the system? As an immortal devil, my only request is to find the inventor of this system. Then! The body was broken into pieces!
