Not long ago, Redstone Gate and Chaotic Blade Sect carried out a joint operation in another city to the northwest. They robbed a government transport flyer.
The items on the flyer, whether unloaded from the sky elevator or from the old continent's industrial zone, were some high-end materials. Even typical lords did not have the means to manufacture these materials themselves.
Or rather, a lord's difficulty in obtaining cutting-edge equipment depends on the research direction and network of his Scientific Knight Order within his domain.
