The Villainous Tycoon's Treasure in His Palm

Also known as A Candy for the World-Weary Tyrant and The Cannon Fodder and the Villain Get Their Happy Ending As the daughter of the Grand Secretary of the Cabinet, Liu Chuyu had a secret from childhood. There was a "System" in her head, and it let her see the overwhelming black aura behind Prince Yan, Li Ning. The System issued a mission: "Exorcise evil and uphold justice." Liu Chuyu did everything she could to avoid Li Ning and make his life difficult. It wasn't until she was reborn at seventeen that she discovered this world was a book. Li Ning was the powerful villain in the story, while she was the white moonlight he deeply loved, who had died young and driven him to become utterly evil. With Li Ning about to ascend the throne, Liu Chuyu thought: ...Is it too late for me to repent now? On the first day of Li Ning's reign. Liu Chuyu was frantic: It's over. He's going to settle the score. That stupid System is forcing me to insult him. Does it think I have a death wish? One year after Li Ning ascended the throne. Liu Chuyu was calm: There's nothing a smile can't solve. And if a smile doesn't work, just say something sweet. The transmigrated-into-a-book woman who had been waiting to save the villain as he turned evil was so angry she spat blood: ??? Are you ever going to die or not? A little scene: When Li Ning saw Liu Chuyu wake up, his body stiffened instantly. He thought she had a temper, and surely wouldn't have anything nice to say. But the girl stared at him blankly for a long time, then suddenly teared up. "Brother Ning..." For those two words alone, Li Ning would gladly live and die for her, part the clouds and reveal the sun for her, and fight through brambles and thorns for her. Reader's guide: 1. Clever, willful, fearless young lady who loves wholeheartedly x a devoted, possessive emperor who is only gentle with the heroine. 2. The male and female leads are natives of the world, while the female supporting character has transmigrated into a book. The story turns the usual book-transmigration and System tropes on their heads. Theme: No matter what difficulties you encounter, stand on your own two feet.
