Through another field test, the improved mining unit once again verified its performance, and this time there were no issues, earning Perfikot's approval.
The improved mining unit was equipped with an ore processing system on the mining barge. The ore collected by the robots would undergo preliminary processing in this system before being transported by the mining barge to the Floating City for further smelting.
With the number increased to four, and after adjustments and improvements, the robots' mining efficiency rivaled that of an entire human mining crew.
In this era, only Perfikot had access to such efficient mining machines, whereas others still relied on the most ancient manual mining methods.
The application of steam engines was limited to pumping water and transporting ore, not truly applied to the extraction of ore itself.
After all, even during the time of the First World War, human ore mining was mainly reliant on manual excavation.
