In 2045, a cyberpunk city in the near future. A full-sensory immersive game warehouse called "Myth Advent" is popular all over the world. It claims to use AI to deduce all the myths in the world. Players can get the ultimate real experience after entering. What was supposed to be an orderly game world, due to the rampage of the mastermind AI, has turned into a chaotic and weird world that combines Chinese folk horror, Cthulhu, and the SCP Foundation asylum. The timeline is messed up, the physical rules change randomly, and NPCs awaken and start hunting players.
