Chapter 81 Slum District

```

According to Lang Zhen's words, beside the prefecture city of Xiyin City, there is also a mountain that easily yields these beautifully ornate stones.

In the beginning, these stones weren't valuable, and everyone mined them haphazardly and picked them up casually.

As time went on, some martial artists who practiced martial arts found that these stones were hard and quite attractive, so they used them to hone their cultivation levels by crafting them into various items.

For instance, the pair of stone balls that Feng Jun bought, Lang Zhen believed, was likely idly crafted by these martial artists.

Of course, since the crafted items were quite attractive, the martial artists could sell them to supplement their household income on top of their cultivation, which was even better.
