In 5047, the Secretary-General of the United Nations stood in front of a charred ruin, with the remains of skyscrapers that once illuminated human civilization behind him. Three years after the outbreak of global nuclear war.
No one can say exactly who pressed that button first. But everyone knows that human industrial civilization was reduced to ashes within three hundred days. The explosion itself only killed one-third of humanity; what really put the survivors into dire straits was the ensuing "nuclear winter" - urban and forest fires sent about 150 million tons of smoke and dust into the stratosphere, blocking sunlight for a long time, and the global average temperature plummeted by about 7°C. The cooling rate exceeded the last ice age, and the food production of major agricultural countries dropped by more than 90%.
Even more terrifying is the nuclear power plant on the seaside.
When Fukushima and Chernobyl-style nuclear power plants were hit by missiles, the ever-extinguishing nuclear fuel rods continued to discharge highly radioactive sewage into the ocean. The ocean, this huge body of water once considered the origin of life, began to breed a new and unpredictable mutation.
Before his death, Einstein said: "I don't know what weapons will be used in the Third World War, but the Fourth World War will definitely be fought with stones."
But he did not say, what if the battlefield of World War IV is in the ocean?
Human civilization has not completely disappeared. There are only about 500 million survivors on land, struggling to survive in the cold, dark, and radioactive ruins. However, in the deep seabed, a more violent evolutionary revolution is underway - deep seawater temperature changes and food chain reconstruction caused by nuclear radiation and nuclear winter are rewriting marine life at a far faster rate than supernatural evolution.
