In 2145 AD, the earth's energy was exhausted. Human beings discovered the remains of the ancient civilization of cultivating immortals in the "Kunlun Ruins" underground city, and converted spiritual energy into data energy (spiritual network), forming a "cyber cultivating immortality" system.
Opposition between two major classes
Cloud monks: A plutocratic family that monopolizes the authority of the spiritual network. They absorb data spiritual energy through the brain-computer interface, extend their lifespan, and control supernatural powers.
Mire dwellers: "people without authority" in surface slums, who can only sneak into the spiritual network and rely on black market prosthetics and forbidden codes to forcibly awaken their abilities, at the cost of mental breakdown or physical deformation.
