The Last Human Race

The core setting of the novel Book title: "The Last of Us: The Era of Each Day" World view background: Gravitational collapse: Billions of years later, guided by the gravitational anomaly of the unknown universe, the Earth's orbit will irreversibly collapse toward the sun. The sun occupies one-third of the field of view in the sky, and the surface temperature is normally maintained at 60°C-80°C. Surface ecology: The oceans have evaporated, leaving only dry salt-alkali lands. Humans have built a "double-walled circulation city" on the surface of the earth, relying on a layer of super-strengthened glass and transparent super coolant to isolate high temperatures. Underground ecology: The vast majority of humans have moved into the "deep rock shelters" deep in the earth's crust, where they rely on geothermal heat and nuclear fusion to maintain ecology, but the space is crowded and the hierarchy is strict. Core conflict: Depletion of survival resources: Coolant raw materials are becoming increasingly scarce, and surface shelters are facing a "boiling" crisis. The choice of civilization: continue to linger on the surface and wait for the earth to be swallowed by the sun, or implement a crazy "wandering plan" to escape from the solar system? Special settings: Light Whisperer: After long-term exposure to the special spectrum filtered by coolant, the protagonist's generation of surface humans has evolved the ability to "see" gravitational fluctuations. Coolant: not only a thermal insulation layer, but also a source of tranquilizers that maintain human sanity (trace evaporation).
