This is a fantasy series and a standard poetry series, each story is completely independent, somewhat similar to the British "Black Mirror" (Black Mirror). The story is inspired by the infamous "404" error code on the Internet, with the theme "all strange things can happen online". It is said that the show is a mixture of science fiction, action adventure, horror comedy and other multi-genres-when you are still in the net at 03:00 at night, you may encounter the dark side of the Internet. See some weird content that can't be explained from a real-world point of view. For example, an obscure cartoon may contain the secrets of time travel, energy drinks can trigger the end of the world, and NASA's top analyst is actually a large, omniscient, perceptive "cube meat" (and called Bob).
