"A Journey to the Daughter's Country" tells the story of Su Jinyu, an editor of the Hanlin Academy of the Dajing Dynasty, in order to find out the truth about the disappearance of his father on an envoy to southern Xinjiang ten years ago. With half a bronze phoenix, she disguised herself as a man and embarked on a journey to find the legendary "Daughter's Country" (Fengqi Kingdom).
Along the way, she teamed up with Qin Yue, a ranger who came to find her father, and Liu Sanniang, a witch from southern Xinjiang who was entrusted by her mentor to help her. They traveled through the poisonous rainforest, deciphered illusions and invasions by alien beasts, and survived the pursuit of the court force "Shadow Guards" and the obstruction of southern Xinjiang tribes, and finally arrived at the isolated Fengqi Kingdom.
Here, she discovers that Fengqi Kingdom relies on ancient spiritual springs and witchcraft to continue its ethnic group, but it is in crisis due to the decline of the power of the spiritual springs, and it hides the ancient secret of the "Saint Sacrifice". Her father's disappearance is closely related to the rebellion conspiracy of Prince Jing, who covets the power of the spiritual springs, and the core secrets of Fengqi Kingdom.
Su Jinyu joined hands with Qin Yue, Liu Sanniang, Queen Huang Xi of Fengqi Kingdom, and Saint Lingxi to thwart King Jing's conspiracy to seize power, break Fengqi Kingdom's "closed self-defense" ancestral system, and promote the establishment of exchanges with tribes in the Central Plains and southern Xinjiang. By introducing agriculture and water conservancy technology from the Central Plains, innovating the witchcraft and laws of Fengqi Country, and promoting the integration of civilizations, not only did the spiritual springs revive and Fengqi Country move towards a new life, but it also solved the mystery of the disappearance of the father's generation, gained love and the value of life, and finally witnessed the story of different civilizations achieving each other through tolerance and openness.
