Feng Shui Notes: Secrets Must Not Be Revealed

Before he died, my grandfather gave me a yellowed Feng Shui note and said that it was a unique secret passed down from our Chen family. I thought it was just an ordinary old book, until I used the method in the notes to read a classmate's face, and his face really changed the next day. If the evil spirit enters the body, death will occur within three days! I was anxious to find a way to solve it, but I found eight words written in blood on the last page of the note: Those who reveal secrets will not die well. People died one after another on campus, things suppressed under my ancestral grave were dug out, the city was changing, ancient beasts were reborn, and all forces poured into Jiangcheng... How should I survive this catastrophe?
