A detailed explanation of Liu Bowen's divination in The War of Heroes.

Liu Bowen looks at five cards at most. When there are less than five people, the number of cards he looks at is equal to the number of people alive.

These five cards can be sorted freely, but they can only be placed at the top and bottom of a pile. The top five boxes are the top of the pile, and the bottom five boxes are the bottom of the pile.

Then, the judgment of "Yan Fei" that both prison and thunder are used: the principle of jade, thunder and prison is to judge first.
