Reborn in the Modern Era, an Ancient Princess Uses a System to Strengthen Her Nation

I’m in a Reading Slump. Looking for Patriotic Stories With a Reborn or Transmigrated Female Lead Who Uses Science and Technology to Serve Her Country, and Has a Male Lead

Looking for books like "Big News! She Became the Youngest Top Academician at Just 18". I’ve run out of things to read, everyone! I like stories where the female lead is reborn or transmigrates from ancient times to the modern day, though other types are fine too. I love patriotic stories about serving and repaying the country. There should be a male lead. They really get my blood pumping.
