After Traveling Through Time for 65 Years, the Cannon Fodder Heroine Turned Over

Space + system + growth-oriented heroine Yu Shuyao wakes up and travels to 65 years. The beginning is at its peak. A year later, she finally remembers that she has traveled through the book and became a cannon fodder. In the beginning, her family went offline and she was forced to give space to the heroine in the book. There is also a system that came late. All-in-one system? I want to see how versatile it is. (The male protagonist appears late)
