A Pillar of Righteousness, but Swapped Bodies with the Demon God

Su Qi was once a female war god of the Celestial Realm, a pillar of the righteous factions. When the Three Realms faced the calamity that threatened to destroy the world, she stepped forward and fought the Demon God Zaiyan alone. She gave up her life in exchange for his promise to end the war. The Demon God Zaiyan stood apart from the Nine Heavens, cold and capricious. Born to bring about the world's destruction, he never made exceptions or showed mercy for anyone. Countless innocent souls had died by his hand, yet hers was the one name he remembered. Reincarnated as a mortal, Su Qi forgot all her memories. She became bound to a mysterious System that allowed her to temporarily switch bodies with the Demon God Zaiyan. * Wearing Su Qi's meek and helpless face, Zaiyan became a great overlord of the cultivation world. His body couldn't cultivate, so he simply forged new spiritual roots for himself. When his lifespan ran out and the Soul Reapers came to claim him, he seized their chains and tied up Black Impermanence. The aunt, older sister, senior brother, and even the renowned assassin who had once plotted against him were all killed by his hand. Anyone who had offended him met a terrible end. Using Zaiyan's body, Su Qi spent her days eating, drinking, and having fun. She lounged carelessly on his personal divine throne. On her left, the handsome, wicked Demon Lord respectfully massaged her back and shoulders. On her right, the gentle, jade-like White-Robed Divine Son lowered his eyes and presented her with a box of treasures. Su Qi: It's getting cold. Wipe out the Wang family. Su Qi: These peaches aren't tasty this time. Bring me a basket of ginseng fruit and then ask for my help. Su Qi: King Yama? Bring me the Book of Life and Death. I want to play with it. Don't make me ask twice. Su Qi: Old Jade Emperor, get over here and become my son at once! * Su Qi thought that after all the outrageous things she'd done, Zaiyan would be the first to kill her once they switched back. Instead, he merely invited her to the underworld, cool and arrogant as ever. Su Qi's mind filled with visions of the Eighteen Levels of Hell, mountains of knives, seas of fire, and all kinds of terrifying horrors. She'd thought he wouldn't just kill her, but torture her in some inhuman way too. No wonder he was the sinister, cruel, bloodthirsty enemy of the world! But all he did was open the Book of Life and Death for her. "Didn't you want to adopt the Jade Emperor? He's currently undergoing a trial in the mortal realm. Now's your chance." Su Qi: ? He said coolly, "Besides, it wouldn't be beneath him to acknowledge this lord as his father." 1. A decisive, world-destroying demon lord x a mischievous junior sister who seems honest on the surface 2. In this setting, the male and female leads switch bodies every so often Coming soon: "The Rich Heiress Reborn from the Apocalypse" Su Momo was a supporting character in a romance novel. Born into a wealthy family, she had nothing but good looks. She was ignorant and shallow, a superficial beauty obsessed with handsome men. Her family despised her, her classmates hated her, and even the dream guy who'd pursued her relentlessly looked down on her and got together with the heroine instead. Su Momo came to hate the heroine because of it. She picked a fight with the heroine, who had everyone's love and affection, and the outcome was predictable: Su Momo was falsely accused of all sorts of things, cursed by everyone, and finally slunk away from City Z, where she died in a car accident. After her death, she was transported to the apocalypse and finally understood everything. She struggled to survive in a world of scarce supplies and treacherous people, making it all the way to the final zone. When she opened her eyes again, she was back at the beginning of the novel. In peacetime, she owned a hundred-billion-yuan fortune, woke up every day in a two-hundred-square-meter bed, and enjoyed the attentive service of her servants. The only thing she had to worry about was how to spend the money in her bank account. Su Momo, who had once fought tooth and nail over a can of food: "...?!" Heaven. This was heaven! To hell with the stupid male and female leads. Wasn't it much better to go shopping, swipe her card, and eat, drink, and have fun? When the dream guy asked to break up, Su Momo agreed calmly. "Sure." The dream guy: ? Didn't she have anything else to say to him? Su Momo: "Oh, right. Don't bother me unless it's important. I need to study, and my time is precious." Later, everyone thought Su Momo had changed. The dream guy came crawling back, begging her to get back together. The school principal cried and clung to her leg, begging for a donation. The other supporting characters fought to get jobs at her company. Even the villain squatted outside her house, looking pitiful as he begged her to take him in. Su Momo: ? She could understand the others, but this little villain was the richest man in the book, a business genius whose fortune had several more zeroes than hers. Why was he camping out at her house and pretending to be helpless? Theme: Rely on yourself to grow stronger.
