Double Penetration in the Apocalypse: I Brought Back Black Technology from the Wasteland

Meng Fan accidentally traveled to an apocalyptic world called the Gray World, where food and resources have become eternal truths, and a simple can of luncheon meat can cause a fight for dozens of lives. Originally a social animal, he ushered in the greatest opportunity. Cans were exchanged for gold, and sausages were exchanged for diamonds. Not only that, when one after another apocalyptic technology comes to reality, countless people go crazy. A certain gang leader: A machete? If you're a man, you have to play with a lightsaber! Chairman of a certain automobile company: I think anti-gravity flying cars are the future trend. A certain mercenary king: Mechas are a man's romance. Don't contact me about body armor. I'm afraid Mark 42 will misunderstand you. ... Meng Fan: Stop pretending, I'm a technological genius and I'm showing off. In this way, he built an extremely powerful technological empire entirely by relying on his own efforts.
