The Su family, a wealthy silk merchant in the south of the Yangtze River, was suddenly wiped out. The talented girl Su Nianyao narrowly escaped because of a broken string in a song, but she was charged with "collaboration with the enemy and treason" and fled north. In a desperate situation, she was forced to accept the protection of Shen Mohan, the young commander of the Northland, and stepped into the vortex of power and war.
The handsome manor is as deep as the sea and full of dangers. The cold-faced secret guard Xuan Ye risked his life to protect him, and the mysterious master Lin Yu appeared many times. Under the competition between various forces, Su Nianyao gradually discovered that her father's death was involved in the shocking and unsolved case of the violent death of the Northern Governor ten years ago. A secret account that records Shuozhou Jiedu envoy Han Kui and the imperial master of the DPRK embezzled military pay and colluded with the mysterious organization "Qingluan Society" has become the key to tearing apart the darkness.
In order to find out the truth, Su Nianyao and Shen Mohan formed an alliance and struggled through court suppression, border wars and internal purges. From Jinling and Qinhuai to the border town of the North, from the broken string pipa to the iron-blooded battlefield, she grew up step by step from an orphan to a chess player. When the war smoke clears, can Nianyao find justice in the broken mountains and rivers, and what choice will she make between her love and her family and country? This is a turbulent legend about revenge, growth and redemption.
