You see, the Industrial Revolution didn't actually begin with all of these big ol' factories. It actually first began when the Wallarmbrust Crossbow started getting attention, makeshift assembly lines were made to increase their production efficiency, but were actually in a circle of four people, handing each other supplies. But they were ended early on due to the Wallarm Massacre, where a worker picked up three finished Wallarmbrusts and killed the other workers, and then went on to shoot five villagers before being killed by a soldier. The Assembly Line would be inspired by this act of trading off the product, which was a turning point of the Industrial Revolution. Of course I'm lying though, do your own homework.
