Su Xiaoli, a poor student who died suddenly in the college entrance examination room, crossed over to the Continent of Ten Thousand Demons and became a bullied, mixed-blood, useless fox. Utilizing her knowledge of physics and electrical science, she pioneered a scientific method of immortal cultivation, treating her meridians as an electrical circuit to break through the shackles of her bloodline. She gets to know Bai Yuexi, Old Turtle, and others, opposes the oppression of the pure-blood faction, and uncovers the secrets of the three-hundred-year-old fox clan coup. Uniting the tiger, wolf, and snake clans to form the Ten Thousand Demons Allied Forces, she awakens the true form of the Nine-Tailed Celestial Fox and defeats the Demon Lord. Finally, she opens up the two-realm teleportation array, promotes communication between humans and the demon clan, reaps friendship and a lover, and completes a legendary life.
