The gun is one of the greatest inventions in Human history! Its appearance holds milestone significance for Human civilization, heralding a new era. It transformed Humans, these carbon-based beings, from initially training desperately and engaging in fierce close-quarters combat with cold weapons, to vigorously developing firearms and using a variety of them to battle from hundreds of meters, or even tens or hundreds of kilometers away.
The reason for this transformation lies in the terrifying lethality and range of firearms. No matter how strong you are, or how muscular your body becomes, as long as you are still Human, a 9mm Parabellum pistol bullet—costing just two to three dollars and mass-produced on an industrial assembly line—can easily injure or even penetrate your years-hardened carbon-based body within fifty meters, disregarding all your skills!
