Core settings
• World view: In 2077, the "Red Fog" swept across the world, and half of the human race mutated into carnivorous "corruption walkers". The survivors hid in the "safe zone" surrounded by high walls to survive. There are not only mutated creatures in the red mist, but also unknown radiation and ancient civilization relics hidden in it. Resources are extremely scarce, and human nature is distorted under the pressure of survival.
• System: The "all things synthesis system" bound by the protagonist Lin Mo after traveling through time. The core function is "decomposition-synthesis" - decompose any material into "original particles", and then synthesize new items according to the formula (as small as strengthened food and weapon parts, as large as mechas and safe zone defenses). The system has levels. Upgrading can unlock more advanced formulas and issue "survival missions" to promote the plot. Failure will trigger penalties (such as temporarily disabling the synthesis function).
• Protagonist: Lin Mo, a modern social animal with a rational and calm personality and mild obsessive-compulsive disorder (reflected in item classification and synthesis planning). Before time travel, he was an outdoor enthusiast and understood basic first aid and mechanical principles. After time travel, he gradually shifted from "survival" to "protection" in the apocalypse.
