In order to save his aunt Li Sanniang who was dying of poisoning, Li Xinghe, a young man from an inn in Yuhang Town, was guided by a mysterious Nanzhao merchant and bravely traveled to the overseas fairy island Lingjing Island to obtain the elixir. On the island, he met Zhao Xin'er, a descendant of the reclusive Nuwa tribe, and got married under the auspices of his guardian, Granny Jiang. However, after returning home, he took "Wangyou Powder" and lost all his memory. In order to fulfill his promise and trace his life experience, he escorted Zhao Xin'er back to his hometown of Nanzhao. On the way, he met Lin Wan'er, the daughter of the martial arts leader, and A Sheng, the young leader of the Bai Miao tribe. He was involved in the dispute between the black and white Miao people and the huge conspiracy of the Eclipse leader to subvert the human world. After experiencing the catastrophe of the Demon Locking Tower, the separation of life and death, and finally facing the crisis of annihilation by the Eclipse Cult Leader and the Water Monster, Zhao Xin'er fulfilled the mission of the Nuwa clan, sacrificed herself, and saved the common people. Li Xinghe inherited the Taoist tradition of Shushan (renamed Tianjian Sect) and embarked alone on a future carrying memories and responsibilities.
