The Fallen Kingdom's Seductress and Her Younger Brother

[Ensemble-wide Delusion, Romance with a Male Lead] A male lead who looks like an immortal, is depressed inside, and is saved by love x a righteous, sunny heroine with formidable martial arts skills. Chang Hui, the younger brother of the fallen dynasty's demon consort, is reborn at seventeen. At this point, Bai Chan's uprising is three years away, and the fall of Great Wei and Chang Hui's death are six years away. After being reborn, Chang Hui figures that since the court is doomed to be overthrown and Great Wei is doomed to fall anyway, he might as well enjoy himself. He's just a spoiled rich kid, after all. He has no talent for saving the country, and taking office would be pointless. He may as well eat, drink, play around, use his Noble Consort sister's influence to bully people, and wait for the end. And so... After all that eating, drinking, and playing, every official in court trembles, falls silent, and gives Chang Hui a grave, penetrating look whenever they see him. Chang Hui thinks to himself: I really am the biggest wastrel under heaven. Even the officials are afraid to mess with me. Who would have thought that Bai Chan, the former rebel leader in his previous life, would come in person to ask for Bai Yun's hand in marriage? "Lord Chang is an immortal descended from the heavens, with the talent to govern the world. I would not dare ask for much, but my daughter admires you deeply. I hope you will accept her!" Behind him stands Bai Yun, gazing at Chang Hui with admiration, dressed in red and white armor, a spear in hand, every inch the valiant young general. His Noble Consort sister at the palace goes further still, clasping his hand with an anguished look. "My little brother has the talent to govern the world, but he refuses to enter the court and become prime minister. It breaks my heart!" Chang Hui stares at his sister in bewilderment and says, "Sister, Great Wei is doomed to fall sooner or later. Let's find somewhere to hide." Noble Consort Chang Yun gives him a meaningful look, then turns away, declares herself emperor, and changes the dynasty, becoming the next Wu Zetian.
