When I was drinking with a friend, my friend told me a story about a rural carpenter harming people. I lived with my grandfather since I was a child, but my grandfather disappeared when I was in junior high school. I didn’t know how to find it, but he left me a letter. So after I went to junior high school, I dropped out of school to work and earn money to support myself. Now I am a hard-working writer, earning some royalties every month to support myself. I thought my friend’s story was a story. But later I accidentally discovered an ancient book hidden in my home. It contained four big words 'Lu Ban's Secret Art'. I thought I would make a lot of money after much effort to get this book, but I was already trapped in one conspiracy after another.
