章 69: The most pleasant sound is 69

Northern Ridge, the largest iron mine controlled by Earl Ronin Fisallo, was also the largest iron mine on Northern Ridge.

After years of development, the area was riddled with wounds, and mining entrances everywhere could be seen, some abandoned and others still in use.

Everywhere, workers rested, these mine workers' jobs were dangerous and very busy every day.

They entered the dim mines, then mined the iron ore, placed the ore into their bamboo baskets and large baskets, and carried it out of the mines with effort.

Then they carried the ore to a fixed collection point, received the corresponding voucher, and after accumulating enough vouchers, they could exchange them for their daily wages.

Such a system ensured the miners' efficiency and, to some extent, ensured the reasonable allocation of time to maintain the high efficiency of the mine.
