Otherworldly Factory Rampage ~Conquering Another World with Trust and Results~

Sorry if this has been posted before 💦 I found it interesting after reading a bit, so I'm sharing it. You can read it on WEB manga services and major e-book/manga apps. An entire factory is transported to another world: Sarie, the second-generation president who inherited his father's factory, accepts a job repairing a mysterious US military device for a hefty reward. The activation of this device sends the entire factory, including its employees, equipment, and buildings, to another world. Scouted by the Demon Lord's Army: The engineers, thrust into a world where the war between humans and the Demon Lord's army is escalating, are treated as outsiders by the hero's side. With nowhere else to go, they end up at the Demon Lord's castle's weapon factory. Changing the World with Technology: Recruited by the Demon Lord's army, the craftsmen apply the know-how and manufacturing spirit of Japanese factories, honed over many years. They revolutionize the working conditions and weapon production for goblins, who were exploited in harsh environments, and strive to conquer the other world with their own technology.
