After transmigrating into the Great Ming dynasty, Pei Yan becomes an idle prince who wants nothing more than to live peacefully, enjoy his food, and laze around. Unexpectedly, disaster strikes. The legitimate daughter of a military family arrives at his door with a sword, bluntly declaring that she is carrying his child and forcefully demanding marriage. He is consequently turned into a laughingstock throughout the imperial court and the public, becoming embroiled in a storm of rumors. Everyone assumes he acts recklessly, but Pei Yan alone knows that there is more to the matter than meets the eye. Behind this farce lies a struggle for power at court and the schemes of various factions, all of whom want to manipulate him as a chess piece. Armed with the immense resources and unparalleled strength he accumulated in his previous life, Pei Yan pretends to comply while lying low and biding his time. He turns others' power to his advantage, carefully plotting each move, and gradually breaks free from the constraints of this tangled political and marital game. Ultimately, he takes control of the entire board and stirs up the winds of change across Great Ming.
