The Rest of Life Is Very Long, We Will Never Have a Future

Chronicle Novel the Heroine Is Reborn Requesting for a Book

It's a chronology. I forgot the exact time before the heroine was reborn. She should have three or four brothers named Liu. One brother is in politics and one is in the army. What is the name of the heroine? Does anyone know what the book is? I forgot 😂😭 I can't find it if I want to read it.
