The end of the world is coming, not with a traditional zombie virus, but with a nanomachine infection called "Chaos Spores." The spores corrode all organic matter and transform it into violent mechanical creatures called "mechanical skeletons". Human civilization collapsed and the steel jungle became a wasteland.
Lu Yuan's mutation allowed him to sense the weakness of the mechanical skeleton and the flow of energy. With this ability, he struggled to survive in the wasteland, and gradually realized that the erosion of spores was not random, but followed some unknown algorithmic logic.
