Pretty sure he was sent after Yuan was recognized at the Mystic realm gates . Plus he said his blood started to boil, I think we will find out about Yuans blood line soon!
i can't understand why he is shuddering just because of other player's looks? Not only he knows most highest-ranked skills,but his fighting capacity with sword also best among players since he grasped sword aura.I don't think he needs to fear from other players?
