The End of the World Is Coming! Deep Sea Zero

Our story takes place in the near future around 2087. A "Twilight of the Gods" global nuclear war instantly destroyed human civilization. However, the real doomsday is not the nuclear explosion itself, but the "nuclear winter" it triggers - thick dust clouds block 99% of sunlight, and global temperatures plummet to minus 50-80 degrees Celsius within a few months. ·Land: Completely buried by ice sheets several kilometers thick, it has become an absolute no-go zone for life. ·Ocean: The shallow sea area is frozen, and only the deep sea below 200 meters still maintains a slightly warm liquid environment due to the earth's geothermal heat and volcanic activity, becoming the last hotbed of life on the earth. The vast majority of humans were frozen into ice sculptures on land, and only a handful of people who happened to be on submarines and deep-sea scientific research stations when the nuclear war broke out survived. Resources are extremely scarce and civilization has regressed. The survivors use submarines as mobile shelters, wandering in the endless darkness, risking their lives for a piece of edible seaweed and a working battery.
