After the System Went Offline, I Started Cultivating Immortality

Qin Mu had just been discharged from the hospital when she was bound to a System. The System said that if she followed it and played a villain to advance the plot, she would receive a generous reward. Qin Mu went along with it. After all, helping others was one of her virtues. But only after she entered the mission world did she realize the problem. She had never played a villain before! How was she supposed to do it? The System was unreliable too, and had gone offline, so she couldn't ask. Help, help, help! Is there an online video tutorial? This is a story about a woman who endures humiliation as a kept mistress. The heroine is the daughter of a disgraced official. After her entire family is executed, she hides in Xiu Fang House. The hero, who leads the raid on her home, takes her back as his mistress. The heroine and hero embark on a tragic romance, resolve the misunderstanding behind their family feud, and set their sights on the imperial family. In the end, they join forces to topple the royal house, with him becoming emperor and her empress. The villain is the evil eldest princess of the royal family, arrogant and overbearing. Unfortunately, she is deeply in love with the hero. He only uses her, then turns on her, and she dies a horrible death. Qin Mu: ??? If you're going to raid a home, then do it thoroughly! Do you even know how to raid a home? The System finally came back online after its stabilizer was repaired. However, the plot had already fallen apart. Its Host had ascended the throne, swept across the world, and unified it. The hero and heroine had long since been reduced to ashes... The Host had played the villain a little too thoroughly! The System exclaimed in shock, "The protagonists are gone, so why hasn't the Heavenly Way collapsed?" Qin Mu said, "Someone whose actions can determine the fate of the entire world is powerful enough to stand against the Heavenly Way." The System nearly fell to its knees. "But... Host, you changed the Heavenly Way. This perfectly good ancient world has turned into a cultivation world... And the hero has returned as a Long Aotian, while the heroine has become a Mary Sue. They're coming back stronger than ever to take revenge on you!" Qin Mu, who had grown bored of sitting on the throne, perked up at once. With a grand flourish, she wrote out an imperial edict and proclaimed it to the world. "From this day forward, all citizens of Great Qin shall follow me on the path to immortality!" Content warnings: 1. A strong female lead who is mentally unstable and has no morals, though she does not cross the line. 2. Her opponents include both men and women, and the story features both men and women. It will not be all male or all female. 3. The female lead is the sole protagonist. This is not an ensemble story, and other characters will not receive much focus. So don't argue about whether the big moments go to male or female characters. They all belong to the female lead. 3. No writing advice, please. This is not a place for moral lectures. 4. The female lead is her own cheat ability. This is pure wish fulfillment, so don't expect logic. Theme: The power of conviction. Once you decide to do something, keep moving forward without wavering.
