In the Xi Kingdom, in order to investigate the cause of his sister's death, Feng Qingsui pretended to be the deceased general's widow and entered the Ji Mansion. He and Prime Minister Ji Changqing went from testing and suspicion to mutual trust. The two went to Hezhou to provide disaster relief and quell rebellion. They relied on their wits and tactics to repeatedly overcome dangerous situations, and their love gradually grew. Ji Changqing was under suspicion due to his father's old case and imperial power, so he faked his death to secretly plot. Chaos broke out in the capital, and he returned to set things right, finally clearing his family's grievances. The two broke through the shackles of the world and stayed with each other, preserving their friendship and life in the troubled times.
