Jiang Yao, a modern woman who failed to pass the civil service recruitment exam, unexpectedly travels back to the Kangxi era while visiting Yonghe Temple, becoming the fourth daughter of a hunter's family in Kaoshan Village. With her natural superhuman strength and modern way of thinking, she hunts for a living, improves pig farming, and leads her family toward a stable life. One snowy night, while traveling, she accidentally saves the severely wounded Fourth Prince, Yinzhen, who has been ambushed. Through a twist of fate, she becomes pregnant with his child and has no choice but to claim that her husband has run away before giving birth to her son, Jiang Jun, alone. Three years later, Yinzhen follows the clues and finds her, insisting on reclaiming his royal bloodline. To protect her family, Jiang Yao takes her son to the capital and enters Prince Yong's residence. As the truth about how she once saved the Thirteenth and Fourteenth Princes comes to light, she is unwillingly drawn into the political turmoil of the Nine Princes' struggle for the throne.
