I Brought the Demon Lord Back with Me

Fu Jinkong was once summoned to another world to be a hero. He worked tirelessly for years, finally saved the world, and returned to his own. But before long, he discovered that spiritual qi revival had begun in his world, and it was also facing an invasion from a rift world. Fu Jinkong, fresh from saving a high-magic, high-martial fantasy world: ?! Fate, what do you want from me? Fate! . In the past, Fu Jinkong was the laughingstock of the capital's wealthy circles. He was the Fu family's only heir, but his gold-digging father and illegitimate older brother joined forces to kick him out. Later, when spiritual qi revival began, gods and demons appeared, and dangerous shadows devoured the land, no one knew what to do. Then Fu Jinkong descended from the sky. He was the world's only savior. It wasn't as if Fu Jinkong returned from saving the world empty-handed. As his reward, the world granted him gifts. He brought back the powers and wealth he'd acquired in the other world, as well as... the Demon King he'd stabbed during the final battle. World: See? I gave you the wealth, power, long life, and beauty we agreed on. Fu Jinkong: Thanks, I guess. . Finally home, Fu Jinkong pounced on the life-size body pillow beside him: "Honey, I'm home!" Then he heard a familiar, cold laugh. He turned around, and there was the gorgeous, white-haired, purple-eyed Demon King, staring at him icily. Fu Jinkong stammered: "Y-You'll always be my one and only!" Theme: Selfless dedication and the wish for world peace
