After Ten Years of Hard Work, I Discovered That There Are Demons in the World

After studying hard for ten years, I discovered on the way to Beijing to take the exam that there are monsters in the world. Ren Xin killed the fox demon with a brick, and at the same time obtained the fox demon's cultivation and the demon clan's "Sun and Moon Observation Method". From then on, the scholar embarked on the path of slaying demons. Demons, ghosts, and monsters will die, as will immortals, gods, Taoists, and Buddhas. If I beat you to death, your skills and cultivation will be mine.
