This is a complete world with rigorous, self-consistent logic and modern social metaphors. Readers need to take a broad, big-picture view.
I. Core Worldbuilding: A Dual-Reality Structure
This world is formed from the overlapping remnants of the online "Surface World (physical layer)" and the "Inner World (Noise Sea layer)."
1. The Surface World (The Physical World)
The current state: It is just like our modern cities, with skyscrapers everywhere, 5G coverage, and relentless competition.
The crisis: As information explodes, human attention, emotions, and fragments of memory pile up in higher-dimensional space, forming the "Noise Sea."
Anchors of reality: Landmarks in the city, century-old shops, even the icon of an app used for years or a popular internet meme. Because so many people have paid attention to and believed in these things, they pin reality in place like nails, keeping the Noise Sea from swallowing the material world.
2. The Inner World (The Noise Sea)
Its nature: An ocean of information made up of humanity's "collective unconscious," "abandoned data," "urban legends," and "unfulfilled wishes."
Inhabitants:
Data wraiths: Vengeful spirits formed from the social media accounts of the dead.
Conceptual beasts: For example, a red battle car embodying "road rage," or a swamp monster embodying "procrastination."
Old gods: Distorted forms of figures from ancient mythology, reshaped by modern information, such as a cyberpunk God of Wealth carrying a QR code.
