Looking for Quick Transmigration Novels With a Female Lead Disguised as a Man 找文，快穿，女扮男装的

I can't remember the title. It was a quick transmigration story where the protagonist always disguised herself as a man. In the second world, the ending had her as the empress and the general together. They were childhood sweethearts. That story left such a strong impression on me, and now I want to read it again, so I'm posting here to look for it. Thank you so much.
