During the summer vacation, my parents were busy with work, but they were afraid that I would have an accident at home, so they asked my grandfather to take me to live with him for the summer. There was no Internet at my grandfather's house, and there was nothing to do there. I heard from my grandfather that my great-grandfather, my grandfather's grandfather, was a warlock. I asked my grandfather to tell me my great-grandfather's story and record it to relieve my boredom. This novel and its characters are purely fictitious.
