Open your eyes again and go back to the age of nine when you can change everything. Scumbag prince? Just turn them away. Love between children? Leave it all behind. Do business to build a family, use money to raise private soldiers, and stir up the situation in the world. The old dynasty couldn't tolerate her, so she became the emperor herself and ruled thousands of miles of rivers and mountains. No male protagonist, only a beautiful career~
