The Ruthless Heaven of the Apocalypse

In 2250 of the old century, oil, natural gas, and coal were depleted due to overdraft use by humans. In order to compete for resources, major countries continued to ask for resources from neighboring small countries, and wars never stopped. The military organization led by M Country has seized almost more than half of the world's resources and is still not satisfied. It continues to expand to further regions. While plundering, humans continue to explore space, use the resources of Mars, and continue to send signals to the outside of the universe. Human civilization also stopped as early as 100 years ago. Natural disasters or man-made disasters, mysterious substances from the sky invade the earth, the earth's heaven is opened, the magnetic field becomes chaotic, science is no longer absolute, civilization begins to die, and the earth gradually returns to the original period. Is it the self-balance of the universe, the invasion of alien creatures, or the self-destruction of human civilization at its peak; mutated beasts, crazy zombies, and the darkness of human nature.
