After Passing Through the Book, I Stole the Halo of the Protagonist

When Murong Qing woke up, she found that she had been transformed into a useless princess with no sense of existence, and was married to her sister's sweetheart as a hostage from an enemy country. In the past, the protons from the enemy country stepped on her as a stepping stone, and later, the green tea sister tried every means to take her life. In order to change the ending in the book where she was tortured to death and dumped in a mass grave, Murong Qing began to work hard to earn points for the system, which was bound to break off the shining protagonist halo over her sister and the protons. But what should we do if we don't have support? It doesn't matter, if you find the most awesome villain in the book, whether you want to be a princess, a female general, or a queen, you can get it.
