A Hundred Carriages of Gold in Exchange for a Good-for-Nothing from the Empress

The young empress of the Great Yu Kingdom traded a hundred wagons of gold for a cripple from the Great Yan Kingdom. But this cripple was the Great Yan Kingdom’s Prince Who Stood Shoulder to Shoulder with the Emperor, its Commander-in-Chief, and the future husband of the Great Yan Kingdom’s Grand Princess. No one knew why the empress would do such a thing. But around this cripple, the whole world began to stir. No one knew how it would all end. (No System, alternate setting, maybe transmigration, probably a story about vying for supremacy. A light read for beginners.)
