Li Yiming is a young man in Chang'an City who was born with "yin and yang eyes" and can see ghosts. One night, Lu Qiya, a female judge from the Underworld Soul Hunting Division, was severely injured while protecting Li Yiming and his family while hunting down a powerful ghost. In desperation, Lu Qiya temporarily transferred her "Magic Power" and magical weapon "Education Pen" to Li Yiming.
