What does the network term metaphysics mean?

Many friends like surfing the internet, but they don't know much about some network terms, such as what does metaphysics mean? Metaphysics originated from online games. When a person is lucky enough to get some virtual items with high value or rare value, there is also a humorous explanation of why he is so lucky, which has a mysterious meaning. Later, it was spread by the internet, and it was mostly used to express people or things that were lucky, accidental or unexplained. Metaphysics in the game refers to special card-drawing methods (mouse itch), (collapse 3), (hearthstone legend) and other card-drawing games. Originally used to refer to things that are unlikely to be believed and can't be explained.
