As Jae Hyuk, Xix is also undead and he formed a contract with a demon, because of that he is mostly fine with any injury he gets. He wants to have revenge on Regis Nex. To get near him, he used Princess Yuan as a hostage, but his plan failed and when Nex ripped his heart out, he endured longer than any other undead, implying that he the necromancer who resurected him has great skills.
