Besides buying it themselves, the Lords also arrange for mercenaries and expedition teams to develop various technology-related Alternate Dimensions.
The Mercenary Guild also releases numerous exploration missions when there's profit to be made.
In this way, the entire Old Continent contributes to mechanical technology, producing a large amount of mechanical-related materials, blueprints, and finished products.
These Lords in the Primitive Magic Civilization have no technology and no high-level mechanics, making top-level blueprints useless to them.
Ultimately, those top-level mechanical blueprints and materials, after much circulation, can only flow back into the hands of the Allied Forces.
With enough raw materials and blueprints, it's foreseeable that the New World will continuously produce Titan-level and Hunting God Level battle armors.
And even some other black technologies.
The Allied Forces then make and sell finished products, buying low and selling high.
