Demon, I'll Give You Three Moves

God said: "If the evil spirit that goes around killing people, setting fires, and doing bad things is an old man, a woman, or a young child, will you spare his life?" Wu Cheng: "No, being old, weak, women and children is not a reason to do evil." "If that demonic creature were your fellow disciples, would you still kill them?" Wu Cheng nodded and said: "Yes! No matter who the perpetrator is, he is an evil person. I have no choice. Only by killing him will he be freed." "What if that monster is you? Can you still do it?" God asked again. "Kill without fail!" Wu Cheng's eyes were firm. "Why? Why are you so callous and ruthless that you dare to do something cruel to yourself?" God was surprised and asked again. Wu Cheng said slowly: "Because, I am a Jingling man. A Jingling man is the messenger who maintains peace in the world."
