My Demon King Is Incredible

Mu Jinghong is reborn on the Tianqi Continent with the Great Demon King System. He was supposed to be a dashing young man, but he couldn't resist temptation and ended up as a live-in son-in-law of the Luo family. Mu Jinghong gazes down at the heavens. “No, I'm still the most powerful Great Demon King in the history of the Tianqi Continent.” Luo Qianchen: “Ha! A live-in son-in-law, and you still dare to run your mouth?” Baili Tu: “Tch. You live off a woman and even showed up at my Fengming Heavenly Sect to put on airs? You really have no shame.” Mu Jinghong's gaze turns sharp as a sword. He gives a casual shiver, picks at his ear, and asks, “What did you say? I didn't hear you.” Luo Qianchen and Baili Tu tremble. “We can't afford to provoke him. We can't afford to provoke him.” Mu Jinghong: “I think I'll go practice my sword instead.”
