She's Serious About Raising Humans

[The mission to save the world has begun! Host, please protect the male lead and help him grow.] The thousand-year-old demon Gu Fanyin is bound to a world-saving System, but the System malfunctions and blurs key information. Gu Fanyin is forced to choose between two options. One is dressed in white and looks frail; the other wears red and is flamboyant. After observing them, Gu Fanyin chooses to take the one in red. He has a determined expression, stunning looks, and a tragic past! The perfect candidate for the male lead! To nurture the male lead and help him thrive, Gu Fanyin buys him the finest clothes, hires the best chef, and prepares the most precious medicines! She successfully turns a frail, easy-to-push-around male lead into an obsessive yandere with overwhelming possessiveness. He’s certainly stronger now, but perhaps not in quite the right way. Gu Fanyin: I’m not sure. Let’s wait and see. It’s only when the Heavenly Dao finally comes looking for her that Gu Fanyin realizes the person she picked up wasn’t the male lead, but the villain, and not just any villain: he’s already destroyed the world once! Gu Fanyin: ... No big deal. She calmly overthrows the Heavenly Dao when it orders her to switch to someone else. She’s a demon, after all! Isn’t it only natural to get a terrible deal when making a pact with a demon? When faced with the System’s belated accusation, Gu Fanyin loudly retorts: What’s wrong with being the villain? He has everything the protagonist has, and more besides. Why can’t he be the protagonist? She’s the Heavenly Dao now, and the human she raises can only be the protagonist! At last, Gu Fanyin embraces the obedient, well-behaved villain and declares the matter settled: He is the protagonist! If you don’t know how to be the Heavenly Dao, let me do it! The Heavenly Dao is replaced overnight, and order is turned upside down. At first, everyone in the cultivation world says: This cultivation world is doomed! Later, the new Heavenly Dao’s devoted fans say: We spoke too soon. Maybe there’s still hope...
