Luo Ayi, the Saintess of Miaojiang, bears the important mission of returning to her hometown to build schools and promote education. Armed with venomous snakes and poisonous gu insects, she returns to the provincial capital and the wealthy Luo family. Her parents openly favor others, while the fake heiress repeatedly frames her, but Luo Ayi pays no attention and focuses entirely on her studies, striving to enter a prestigious university. To improve academically, she meets Lu Chen, a top student. After Lu Chen's mother is left in a vegetative state following a car accident, a deep rift develops between father and son. Luo Ayi uses her gu techniques to awaken his mother and resolve their conflict, gradually winning Lu Chen's heart. With the national entrance examination approaching, she drives away evil spirits to accumulate an enormous fund for building schools, while effortlessly crushing the wealthy family's attempts to make things difficult for her with her gu skills. On the day her true identity is revealed, she claims the top score in the national examination and returns triumphantly to Miaojiang with Lu Chen, her repentant younger siblings, and valuable educational resources.
