[Sword and magic + travel through books + different world + love + funny + relaxing + single female protagonist + light novel] Dressing as a heroine and passing by, is there no system? Lu En didn't panic at all. He was relying on his entrepreneurial experience in his previous life and was able to thrive in a different world in just three years! The original heroine Redona was a natural swordsman, aloof and able to fight, but she was photographed by the original hero Hughes because of her status as a slave. That guy is the young master of a magic family. With him spending resources, the heroine can cheat all the way and become the best swordsman in the world! How could Luann, who knew the plot, let Hughes succeed? At auction "The starting price is 50 gold coins." "One million gold coins!" Lu En held up the sign, confident. "3, 2, 1, Deal!" The final word. On the way home, Luen stared at this "Redona" and felt more and more uncomfortable. Why is this "Ledona" so happy after being sold to the cold and stubborn genius she promised to be? ! The smile that can't be hidden at the corner of the mouth... Hey! You're almost jumping when you walk!
