I heard that disc fairy is very powerful. Can it be used to predict the two-color ball?

This thing, disc fairy, is for "ghosts" to guess.

Some people say that advanced people invite Buddha, immortals and so on. For example, if we have no right way, we can only invite ghosts, and it depends on where we play disc fairy. Some places can only invite ghosts for 300 to 400 years, and some places can only predict the past when playing disc fairy. It is said that it is quite accurate, but it is difficult to predict the future. Maybe it's easier to invite ghosts than to send them, hehe.
