Nuclear Change Takes 10,000 Years

As there are more and more nuclear bombs in the world, after a large meteorite hits the earth, because the meteorite contains a large amount of radioactive material, it triggers a global nuclear explosion, leading to the extinction of most of the world's animals and plants, and human beings are almost extinct. I don't know if it is lucky or unfortunate, but a young fish in the 21st century miraculously survived because he was working in a cold storage and was forced to freeze because of his disability.
