Great Ups and Downs

This is a world where due to the excessive development of human science and technology, weather and climate, damage to the natural environment, resource depletion, biological pollution, nuclear pollution, etc., The global population has dropped sharply. Most countries have disappeared due to rising sea levels, and the only remaining government agencies in the world can only maintain some simple order. People who have experienced this global disaster call this disaster in human history the Great Ups and Downs! After the Great Depression, the world has undergone earth-shaking changes, and the human living environment has become extremely harsh. The people at the bottom struggled to survive. Social order has collapsed, morals and ethics have disappeared, and the ugliness of human nature has nowhere to hide in this apocalypse. The surviving people at the bottom will do whatever it takes to survive, snatching food and resources, and even killing each other. At the same time, there are monsters polluted by nuclear-contaminated organisms that are encroaching on people's living space, while the dignitaries and official wives of the pampered government departments are intoxicated in a world of luxury and wealth, turning a blind eye to the suffering of the people at the bottom. They live a luxurious life, regardless of the future of mankind, only caring about their own enjoyment and power.
