In the mysterious annals of an imagined ancient history, an astonishing exchange of souls sets a legend in motion. He was a frontier general who had made his name on countless battlefields, but now he is trapped in the body of a marquis's legitimate daughter. She was once the pampered jewel of a marquis's household, but now she must shoulder the body of a general.
Disguised as a woman, he navigates the treacherous currents of court politics, schemes and competition for power, advancing step by step toward the throne in a woman's guise. The top scholar is the confidant whose soul resonates with his. On the war-torn frontier, she has no martial skills to rely on, but puts the strategic wisdom she developed in the inner household to good use. Together with the mysterious, cross-dressing army medic, she overcomes one crisis after another and leads the army to glory at the most critical moment.
They have never met, yet they are like twin stars bound together by fate. Each seeks the brightest light in a troubled age, and together they write a legendary epic concerned not with romance, but with power and ambition.
