In 202X, Hong Kong suffered a sudden "red fog catastrophe" - a permanent scarlet fog rose in Victoria Harbor. The fog area covered the entire Hong Kong, and the city was completely isolated from the outside world. A different space named "Field" emerges in the fog, dragging random survivors into a game of life and death. The game is controlled by a mysterious "chess player". Victory will obtain "survival authority" (extending the survival time in the fog zone) and "Gap Fragments" (clues that reveal the truth of the world). Failure will be swallowed by the "shadow" in the fog, and even traces will no longer exist.
Science fiction core: The red mist is the "consciousness filter" of high-dimensional civilization, and the earth is its experimental field for observing human nature. The essence of the "field" is the virtual trial space constructed by the projection of consciousness, and the eclipse is the waste of consciousness produced by the collapse of space rules. Every choice made by the survivors will be converted into data for high-dimensional civilization to study "the survival limits of low-dimensional intelligent creatures."
