Doomsday Mechanism: Progressive Geomagnetic Collapse (You can learn countless real survival methods and knowledge here)
The Earth's magnetic field did not disappear instantly, but declined exponentially within 18 months. This results in:
1. Cosmic ray penetration: Surface radiation increases by 5% every month, reaching fatal levels in the 12th month
2. Climate chain collapse: ozone layer destruction → ultraviolet surge → photosynthesis disorder → collapse of the bottom of the food chain
3. Crustal stress release: The world has entered a "super active period" with frequent volcanoes, earthquakes, and ground fissures.
4. The biological navigation system fails: the migration paths of birds, fish, and insects are completely confused, causing ecological disasters.
5. Exposure of human implicit dependence: subway outage (maglev), power grid paralysis (geomagnetic influence on transformers), communication interruption (ionospheric disturbance)
