In Yila's understanding, agriculture was an extremely important matter, followed by the military, and then everything else... The need for manpower in agriculture in this era was immense.
Of course, this did not mean that other things were not important, but in the Demon King Territory... the importance of agriculture was even more exaggerated.
The reason was simple. If it were in the empire, those farmers, when they did not farm, had no other useful skills. They couldn't become warriors or magicians.
The constitution and bloodline of the civilians simply did not reach the required standards.
However, it was different in the Demon King Territory. If the little demons and goblins could be freed, they would have the potential to become professionals. The warrior roles for goblins were not of much concern.
