Near future (about 2150). The earth's resources are on the verge of exhaustion, the environment is deteriorating, and the gap between rich and poor is huge. The concept of the state has weakened, and a few giant technology conglomerates ("giant companies") actually control the lifeblood of society.
Eternal Oasis: The pinnacle of human technology. A global immersive virtual reality network managed and maintained by super artificial intelligence "Noah". Human beings "log in" through neural interfaces and live, work, entertain and socialize in them. The sensory experience is the same as reality, if not better. The flow of time in the "oasis" is adjustable (usually slower than in reality). It is not only a "paradise" to escape reality, but also a core carrier of economy, politics and culture. The real world has become the energy and hardware base that supports the operation of the "oasis", and ordinary people live in the "oasis" most of the time.
Consciousness uploading and immortality plan: The "Other Shore Project" led by the giant company "Creation Technology" has achieved a breakthrough. In theory, human consciousness can be completely scanned and uploaded to the deep core of the "Oasis" - the "Eternal Sanctuary", to achieve digital immortality. But the technology is extremely expensive and ethically controversial, and is only available to the rich and powerful.
