Sunagakure, this backwater village, was truly short on manpower!
As its industries multiplied, so did the jobs they provided. As a result, labor shortages had begun to emerge.
Although Sunagakure was one of the Five Great Ninja Villages, its population wasn't large. Otherwise, the Second Wind Shadow wouldn't have created the Puppet Technique to make up for the shortage of manpower.
Fortunately, Sunagakure's mechanization was, to some extent, relatively advanced.
For example, the production line at Baki's Gold Prospector Factory had been personally designed by Kabuto. It greatly reduced the village's need for manpower and could be considered a primitive semi-mechanized factory, I suppose~
The only regrettable thing was... its power came from burning coal. Although this world possessed a clean energy source called Chakra, the development of ordinary people still followed the same path... hydropower, thermal power, and electricity.
Therefore, the coal consumed by the village had been steadily increasing lately. Most of it was purchased from the capital of the Land of Wind, so they had spent quite a lot of money on coal!
Ninja, huh... how could they ever think of mining or searching for ore veins themselves? After all, finding ore veins was something noble lords did. What did it have to do with them, the ninja?

Though ninja appeared to possess terrifying supernatural powers, to some extent, they still depended on ordinary people for their livelihoods.
As for why such a distorted world had come into being, who... knew?
Therefore, for the construction of Sunagakure, they still had to find ore
