Lynn's mind moved as he opened the [Holographic Map] to check the site of the open-pit coal mine.
Five hundred excavation workers, divided into various tasks, were working diligently.
Although the open-pit coal mine now only had a ten-person team for supervision, the workers were self-motivated even without guards at some posts.
Lynn looked at the excavation site, where three hundred workers were swinging their Iron Picks or Iron Hoes.
Fifty workers responsible for breaking were swinging Iron Hammers weighing dozens of pounds to crush large coal chunks.
Thirty workers were responsible for loading the crushed coal chunks into the carriage holds of horse-drawn carts.
Transported by twenty horse-drawn carts, the coal was taken to the foot of the mountain, where eighty workers performed secondary crushing and screening.
Then, transported back to the town by twenty carts for storage!
Soon.
Lynn discovered the crux of the problem.
Transportation!
