As documented in literature, this type of natural sulfur ore had already been known as 'sulfur' from as early as biblical times after its discovery. In ancient Egyptian and Grecian records, sulfur was used in medicine and fumigation.
Sulfur mining activities during that era were mainly conducted in volcanic areas like Sicily. Up until the 20th century, sulfur deposits could also be found above salt domes. These two areas were the primary sources of sulfur ore.
"Regardless of how one looks at it, this terrain doesn't look like a place where sulfur ore can be found. Is it true that the resource points had been placed at random locations or were there volcanic activities here before the launch?"
Su Mo found bits of the gravel-like sulfur ore after carefully excavating the soil.
