I Know How to Calculate in Mayi

My name is Wang Er*. This is the name given to me by my grandfather Wang Tianlai. I have never seen my parents since I was a child. My grandfather raised me single-handedly. However, my grandfather's identity seems to be very mysterious. He knows things that many people don't know. For example, there are people who drive luxury cars and ask my grandfather to come out and tell fortunes for them. At that time, I didn't know that this matter would be so complicated.
