The “thing that we earned” that Duke Winnes mentioned was the military magic machine technology that the Frestech Chamber of Commerce would transfer to the Winnes Duchy, which they would get once they had reached the level of a second grade magic machine industry.
Other than the research, the Frestech Chamber of Commerce would also send some technical staff to help the Winnes Duchy digest this research material, allowing them to independently produce military magic machines.
Of course, with the Winnes Duchy’s current magic machine industry, they would at most be able to make low grade military magic machines like the Magic Repeating Crossbows and the small Magic Trebuchets.
What Garn Sauron had just said wasn’t wrong at all. Even if the Frestech Chamber of Commerce gave high grade military magic machine technology like the Magic Cannon to the Winnes Duchy, they wouldn’t be able to grasp it.
It had to be known that they could barely grasp the most basic foundations, so they were far from being at the level where they could produce Magic Cannons.
