The Great Yu Dynasty was an imaginary oriental fantasy world where martial arts were prosperous but undercurrents surged. In this world, evil spirits are not ordinary beasts, but are transformed from indescribable "turbidity" that can undergo distortion. In order to fight against this terrifying force lurking in the dark, the Yu Dynasty established a special martial arts institution, the "Shenwu Academy", dedicated to cultivating monster hunting talents.
The protagonist of the story, Li Xuan, is the prince of Dayu who lost his country. In a thrilling palace coup, the powerful minister Zhao Feng usurped the throne and his father died. Li Xuan was deprived of his cultivation and locked in the lowest level of the Heavenly Prison, waiting for the Queen to be executed. However, in a desperate situation, he awakened the "Eye of Cangjian", absorbed the remaining power of the ancient evil suppressed deep in the prison, and successfully escaped from prison and was reborn. After that, he kept his name anonymously and was admitted to the Shenwu Academy as the "Son of Orion in the North". During the day, he competed with his talented classmates; at night, as a demon slayer, he solved strange cases and took revenge on the usurper.
Intention: Li Xuan starts with a waste body (cultivation level is abolished), and starts to practice again from the body tempering realm
