After Lin Xiheng, a laid-back novelist, stopped updating her story, readers tore into her. When she woke up, she found herself inside her own book as the legitimate daughter of the Duke of Guo's household, after unexpectedly binding to the Little Tomato System. To keep the novel's world from collapsing, Lin Xiheng had to stop the villain from turning evil. But she mistakenly identified the villain one day and nearly caused a disaster. Lin Xiheng saved him at the cost of her own life, then temporarily faked her death.
Mu Beili, the emperor's uncle and regent who assisted with state affairs, had spent half his life fiercely independent and on the battlefield. He never expected to fall for a village girl. They met in a mountain village, and when he revealed his identity, they were at death's door. She gave her life for him. He searched for her in vain, lovesick and ill. Little did he know that when they met again, the blind girl from the farm had become the legitimate daughter of a noble family, a dazzling beauty of the capital.
After completing her mission, Lin Xiheng said her final farewell to the great villain and faked her death to return home. She never expected the villain to... turn evil overnight!
Before Lin Xiheng could return home, the System brought her back to the world of the book. "Host, the great villain has turned evil, and the world is collapsing! It's up to you to save it!"
