Black Mountain City was not a city that survived on Demon Beasts and medicinal herbs.
They had mines.
In the heart of Celestial Barrier Mountain lay a massive vein of Profound Iron—one that, according to them, was large enough to sustain Black Mountain City for eight to ten generations.
As a result, ninety percent of the Cultivators in the city were miner-cultivators.
These hard-bitten toilers, who treated descending into the mines like taking a drink of water, naturally looked down on the city's other Cultivators.
Guarding the vein didn't make them rich, but it offered stability. As long as they were willing to work hard, they would never lack for cultivation resources.
Perhaps because Profound Iron was so plentiful, most of the city's buildings were constructed with it, lending many areas a deep, somber sheen.
