He who gets that book rules the entire nation. Reportedly, in ancient times, deity made the royal family keep the book, as a sign of acknowledging their ruler-ship.

When Han people regained the ruler-ship in Ming dynasty, though the deity's book was found back and enshrined in the Imperial Palace again, those outlaw forces already knew that the book was more than just a legend! It did exist! So they plotted to steal it out. There are there most famous robbers in the outlaw societies: Hell-fire monk, Hua Daochang the thousand-face fox and Duan Yun in white.
