It's the kind of dirt and rocks with some coal mixed in, but not very pure.
Looking at the sight before him, Chen Yang became even more convinced of his inner thoughts.
This mine tunnel isn't for digging coal; it's very likely specifically for excavating those magical stones.
Otherwise, why would anyone come here, to a place with low coal content, and dig out such a large space when there are plenty of coal mines above?
"Maybe I can try my luck."
Knowing this is the primary production area for the stones, Chen Yang instantly became interested again.
In this living room-like mine tunnel, he found an abandoned digging tool and chose a spot that looked promising, starting to dig.
Since he knew this place was probably a major source of the stones, he dug with enthusiasm.
After about ten minutes of digging, he had already excavated quite an area.
Although he hadn't yet seen any of those stones, he didn't give up and kept on digging.
