Useless Female Official: After Becoming a Disciple of the Disabled Commander, I Gained Power in Both the Government and the Public

Dressed as a young girl from the bottom, with no system or powers, she was framed and exiled at the beginning? It doesn't matter. They don't know that the Ten Thousand Volumes Library where I am imprisoned is my arsenal. Every mutiny and every power struggle recorded in history books is my sand table deduction. They expelled me from the court back then, but now I have come back with the power and wisdom of three thousand years of history! Are you laughing at me for not being able to tie a chicken? I will use knowledge as a sword to make you kneel down and surrender!
