Why Can't He Die?

"Quick, quick, catch that devil right away!" Everyone rushed to the edge of the cliff and saw the man in front of them standing with his hands behind his back, his back to the heroes.

"Devil, you have taken away my property and bullied my children. You and I are at odds with each other!" "Devil, you disregarded the right path and sacrificed the whole city. You and I are at odds with each other!" "Devil, you... You - you robbed me of my womanhood and caused me to lose my wife. You and I are incompatible with each other!" Everyone: "???" I saw the man on the edge of the cliff slowly turning his head and showing a harmless smile: "I already know what happened to you, and I think you all know the truth afterwards. I just want to ask you, which of you can kill me?"
