After Passing Through the Book, He Stole the Heroine's Heart-Throb Attributes

[Farming + no golden fingers + no space + getting rich] Shen Li was a Ph. D. In chemistry and was known as an experimental madman. She died suddenly after staying up for two days and two nights for an experiment. Then he passed through the book and became cannon fodder with the same name and surname in the book. The original owner was a lover, and he liked the male lead and ruined the family, so he had a falling out with his family, so Shen Li became a person that even dogs disliked. Thinking about her fate in the book, I felt cold all over. She has three brothers. The eldest brother inherited his father's last wish, studied hard, took the imperial examination, and became an official. The second brother has extraordinary talents and superb craftsmanship, and has become a great master of the generation. The third brother has great martial arts skills and has made his way through the world, becoming a respected hero. But after her death, all her outstanding brothers became the heroine Shen Yanyan's backers. How could this be allowed? She must get rid of the cannon fodder ending, work hard to survive, and train her brothers to make them better than in the original book. Her brothers can only be her backers, how can they become someone else's? But why doesn't the male protagonist in this book follow the plot? Instead of chatting with the heroine, you just come to stare at her? Think about how he dotes on the female protagonist in the book? Unwavering determination? Shen Li felt that if he only did this to her, it would be quite heartwarming.
