In a dynasty steeped in ancient elegance, Xie Mingyi, a young princess doted on by the Empress Dowager, once insisted on marrying the nobleman Lu Zhi, only to end up alone in an empty courtyard. Reborn at the age of fifteen, she vows to cut ties with the past, don armor, take up her sword, and become the one who controls the game. On a night when lanterns light the streets like daylight, Lu Zhi, eyes bloodshot, blocks a bridge and begs her to turn back. Xie Mingyi only smiles coldly and sweeps past him, taking the hand of the stoic general she once wronged. As snow falls on the capital, the once-revered young nobleman crosses a thousand dangers to atone, while she makes the realm her board and soldiers her pieces, grinding their old love and hatred to dust. How will this tragic historical romance unravel the misunderstanding that kept them apart in two lifetimes, and how will they find their deepest devotion at the end of the war?
