After Passing Through the Book, the Legitimate Daughter Counterattacks

It doesn't matter if you dress up as cannon fodder, or you bind the system to defeat the villain - as long as you have enough brains, the original novel will call me "Daddy." The all-powerful heroine wears the form of cannon fodder and is bound to the system to defeat the ultimate villain - she doesn't fall in love, she just saves her life, and she accidentally becomes the king of the new world.
