In the midst of a ruined forest, due to the result of the clash between peak powerhouses, a body of a man lay. He was known as the 'Evilest Villain', the worst man ever born in humanity.His body was full of wounds with a spear piercing his heart. However, even in his final moments, he was calm and collected, with his usual cold face.

The only thing on his mind was, “Forgive me, I couldn't keep my promise to you.”
