In 2147 AD, the world was suddenly shrouded in "scarlet haze" - a suspended particulate matter that was light blood-colored and had a metallic smell. The fog indiscriminately erodes biological genes. Human beings initially thought it was industrial pollution. Three months later, mutated organisms appeared on a large scale, and the civilized order collapsed. The "scarlet haze" has lasted for seven years so far. The cause is unknown. It is only known that the concentration of haze changes with the region. The haze in the core area (formerly the center of a large city) is dark purple and has the highest risk level.
2. Environmental characteristics
Topography: The original modern city has been reduced to a "rusted ruin". Translucent "fog velvet fungi" grow on the slumped places of high-rise buildings (it will cause slight paralysis when touching the skin). The rivers are dyed light red by the mist, and only the deep underground water is drinkable. In some areas, "fog vortices" are formed due to the accumulation of mist. Those who enter will be disoriented, and the density of mutated organisms is extremely high.
Resource system: The food is mainly composed of "compressed nutrient blocks" (synthesized from plant fibers extracted from ruins) and edible parts of mutant organisms; water sources need to be processed by "mist filters"; the core resource is the "source core" - light blue crystals condensed in mutant organisms, which can be used as fuel to drive equipment, and can also awaken some humans' "resonance abilities".
