Lu Chengyuan, a retired soldier-king, was framed and sent to prison four years ago. By the time he was released, his family had been swallowed up, both his parents were dead, and his younger sister had vanished.
Under the name Chen Yan, he returned to Linhai and rescued Shen Zhiyi, the heiress of the Shen family, when she was cornered at an intersection. He became her personal bodyguard.
By day, he protects her. By night, he settles old scores: Who swallowed the Lu family? Who handed over the knife? And who in this city is waiting for him to return?
Keeping his intentions hidden, he forces the people from that year out of the shadows, one step at a time, until the last person is someone he least wants to see.
