What does the network term metaphysics mean?

Metaphysics in network language refers to a humorous explanation of one's good luck. There is a mysterious meaning, which was later spread by the internet. It is often used to describe someone's luck in something, which means it happens by accident, or it can mean an unexplained phenomenon or event. Metaphysics, as a philosophical thought of China in Wei and Jin Dynasties, appeared in ancient times, and its origin in online language originated from online games. When a person is lucky, he can generally get some high-value or rare virtual goods. At this time, some people will describe this situation as a kind of "metaphysics", which was originally used in some card-drawing games, and later began to refer to something with very slim chances. It sounded impossible at first, but it did happen later, so the word "metaphysics" can be used to describe this inexplicable mystery.
