In order to avoid being hunted, the two pretended to be a couple and embarked on their escape. Jiang Fan relies on otherworldly knowledge and hidden strength to resolve the pursuit of the Black Sail Gang, the intrigues of the court, and the crisis of the Northern Barbarians, and helps Ying Wushuang seize the imperial power. The two gradually fell in love as they stayed together in life and death. Eventually, Jiang Fan was named the emperor's son-in-law, and he and the empress shared power in the government and guarded the country of Qin.
