An unknown scheming spirit residing in Xuan Yuanze's mind. It speaks in an old man's voice that sometimes changes to a mechanical metallic voice. It wants to kill Cen Shuangluo (the demon dragon) and urged Xuan Yuanze to do so. It taught a heart technique to burn the soul and convert life force into true essence to temporarily reach Spirit Separation stage power. It was surprised that its plan to use Xuan Yuanze failed.
