After Passing Through the Book, I Used the System to Modify the Plot

[Traveling books + eating melon system + voice + rich family + boss + having CP + real and fake daughter + group pet + modify the plot] Tang Youyou traveled through the book due to an accident, and also traveled into a Mary Sue romance novel that she had just read some time ago. The content of the novel is very bloody. Her identity in the book is the real daughter of the Tang family, the top wealthy family in City A, who was accidentally lost when she was a child and just returned home. She is familiar with the plot and knows that her family, including the fake daughter, are all cannon fodder. When she was worried, she accidentally bound a melon-eating system and gained the ability to modify the plot (can be used as a homophonic joke). What she didn't know was that her voice could be heard. See how she uses her golden finger to change the fate of her family and reach the top of her life.
