The steam engine was working, its rotating flywheel driving a series of gears, which pulled the ore carts, chained together, one after another, out of the mine shaft.
The miners waiting nearby, under the guidance of workers from Tang Mo's Great Tang Group, easily flipped the lever above, disengaging the rotation of the steam engine from the entire mechanism, and thus the carts came to a stop.
On the other side, workers by the tracks stepped forward, tipping the ore carts filled with ores to one side, dumping the contents out.
The remaining miners hurriedly shoveled the ores to a farther location, the whole process flowing smoothly, with unimaginable speed.
This was but the first revolution of the mine, and with more mining equipment to come, the speed at which humans mined ore would soon increase tenfold or a hundredfold, fast to a terrifying extent.
