A Menial Qi Refiner from the Start, I Force-Kissed the Demon Empress

[Cultivation romance and everyday life + one domineering empress heroine who falls for the protagonist + exposing two-faced women + no System, no rebirth + obsessive demon lord forces him into love + marriage before love + sweet romance + no angst] Chen Chang'an has just been dumped by his two-faced childhood sweetheart when a breathtaking empress of unknown origin drags him into signing a marriage pact. He isn’t even an inner disciple, yet he already has a “marriage certificate” with the empress. He assumes it’s just an absurd, rotten stroke of luck, forcing him to serve as a shield... But when he returns to his sect and sees the Netherworld Empress, feared by both the righteous and demonic paths, descend from the sky, he is completely stunned. Good heavens! The woman who forced him into the pact is none other than Luo Jiuyou, the lofty, ruthless Demon Empress of the Jiuzhou Realm! He thinks he’s been forced into becoming the Demon Lord’s kept man and will be ground to dust by some righteous powerhouse at any moment. But when a prodigy from the Immortal Dynasty shows up to cause trouble and he faces a deadly crisis, his own aloof wife throws out ten top-grade spirit veins and secretly protects him, instantly crushing every enemy. “Don’t be afraid, husband. I’ve got you covered in the Jiuzhou Realm!” “???” Chen Chang'an realizes his wife seems to be more than just a Demon Lord. She’s an absurdly wealthy, fiercely protective wife, and an obsessive lover who desperately needs reassurance! Before the pact: Even if I, Chen Chang'an, am struck by heavenly tribulation or pierced through the heart by ten thousand swords, I will never live off my wife! After the pact: Wife, come cuddle! Ten spirit veins aren’t enough. Give me some more pocket money to build a grand formation!
