Seven Lives and Seven Lives: King of Hell, Please Let Me Go

"Let me ask you one last time, are you really going to become a demon for her?" "Yes." "Even if I cut off my lifelong cultivation, destroy my immortal bones as the King of Hell, and abandon everything I own to become a mortal, will this still be the case?" "Yes." "Don't you think you need to give me an explanation? Why are you willing to become a demon instead of being with me? Are you not a demon slayer?" "She is different. She cannot choose her origin. She also does not want to be a monster." "Then am I willing to be the King of Hell?" "Let me go! Let us go!" "I will kill you." "Then kill her! The one I love is her." "If you really ask for it, then I will grant it to you. After I kill her, I will come and take your life."
