Why Is the Savior a Villain? !

The Demon Lord was forced to be a good person? This good man is no longer in his rightful place! After being bound to the moral saint system, the evil demon Lord Ye Xiao was forced to start a strange daily life. He had to deliver holy medicine to his archenemy, help an old lady cross the River Styx, and teach a righteous fairy how to make an evil elixir. When he finally got used to using villain thinking to complete system tasks, the system suddenly upgraded - asking him to save the world? Night Owl looked at the new mission and sneered: "You want me to be the savior? First ask my forty-meter swordsman if he agrees!" But when he found the girl of destiny with a knife, he saw the girl raised her clear eyes and whispered: "Big brother..." The butcher knife clattered to the ground in his hand. ——This good man seems to be destined for me?
