The Book of Changes was an ancient Chinese divination technique that used calculations on all things in the world to explore the fate and future of mankind. The most expensive fortune-telling master diviner of the Book of Changes might not exist in China because fortune-telling divinations of the Book of Changes did not belong to the commercial field but a traditional culture and belief. However, some novels might describe some mysterious diviners who could even predict the fate of mankind and the mysteries of the universe. The diviners in these novels might have superpowers or mysterious powers that could use the divinations of the Book of Changes to explore the fate and future of mankind.
