😋My recommendation is Lu Bu: My Wife Comes From Two Thousand Years Later. This book was a historical novel about the Qin, Han, and Three Kingdoms. The main character, Lu Bu, had a system installed on his body after he transmigrated, which changed the trajectory of his life. The story is full of ups and downs, and it's very interesting. More importantly, it meets your requirements. It's a single female lead, time-traveling, and a male lead. The longer the story, the better. I hope you like this fairy's recommendation. Muah ~😗
