Can you recommend an ancient novel about the rebirth of a legitimate daughter and her revenge?

The female protagonist was the legitimate daughter. After her rebirth, she coincidentally saved her non-biological "younger brother". In fact, she was not the younger brother and was older than the female protagonist. In the end, the two of them were together. [Note: The female lead seems to be a Di daughter.] Kneel and beg for the title of the book. If you answer correctly, you'll get free points.
