Help, I Really Don’t Want to Be the Demon King

{System, multiple heroines, hero and demon king} God said, “Let there be light and darkness, sky and earth, and the turning of the seasons.” Thus God created this world. But the gods sit high above, while suffering abounds below. The Demon King and the heroes have battled for a thousand years. Countless people have been reincarnated, and the whole world is a complete mess. So who in their right mind would want to spend every day struggling to survive in a backward medieval world like this? Looking at the terrifying dragon before him, Jun Luo couldn't help cursing out loud. At long last, he'd awakened a cheat ability, only to be made the villainous Demon King, destined to duel the strongest hero in history. He gave up completely, but fate kept pushing him forward, bringing him into contact with all kinds of people. A borderland general who's gentle only toward him; a sweet succubus who used to be a holy maiden of the Church; an older elf queen who's still obsessed with acting cute... At the end of the story, on the day the stars fall, he bids farewell to the gods! The hymn of humanity is a hymn to courage! There probably won't be any heartbreaking tragedy, right? Yeah.
