I Really Didn't Destroy the World

After traveling to a world with supernatural powers, Yin Gyu wanted to enjoy life, but what he didn't expect was: What does it mean for a beautiful girl to be sacrificed at the same table? Why do I keep dying? Are the depressed transfer students waiting for me to save them? Sister Yu, the superpower, thinks I'm a succubus? Do I still want to save the world? Yin Gyu thinks it is better to destroy the world.
