Time setting: The near future, 2035. Quantum computing and biochips have become widespread, but interstellar travel has yet to be achieved.
Location setting: The story begins at the Shanghai Institute of Quantum Computing, with its main settings shifting between parallel worlds, including a wasteland, an antigravity metropolis, and an interstellar society, three typical visions of the future.
Background: Humanity has discovered quantum resonance, which allows information to become entangled with parallel worlds at specific frequencies. The technology was originally developed for communication, but it unexpectedly opened up the possibility of consciousness transmigration.
