My Archenemy, the Demon Lord, Became My Husband

[Decisive heroine VS unhinged Demon Venerable] In her previous life, Li Muge was unsatisfied with being merely a guardian in the Demon Realm, always being outdone by her rival, the Demon Venerable Yun Qi. After years of careful scheming, she finally staged a coup. Branded a traitor, she dragged the aloof Demon Venerable Yun Qi from his pedestal, crippled his spiritual roots, destroyed his cultivation, and sealed him in purgatory. She thought she could then sit easy on the Demon Venerable's throne. But Yun Qi, having fallen to the depths, turned the tables and outmaneuvered her, imprisoning her in a lightless abyss for tens of thousands of years. At the end of her life, Li Muge finally saw the light: to hell with power struggles. If she could start over, she would become a proper slacker and swear never to be the Demon Venerable. To her surprise, when she opened her eyes, her wish had come true: she had been reborn. But she had returned to the very day the enemy stood at the gates, when she herself had cornered the Demon Venerable Yun Qi and forced her way into his palace.
