The number of accompanying fog caves is not yet fully counted, but it is expected to not be less than the amount during the last outbreak.
At least... over a thousand!
On average, one fog cave is generated every 100-150 square kilometers.
These fog caves might cluster together in one place, or they might be particularly scattered, varying in size.
According to previous records, the longest one lasted nearly 8 hours, while the shortest lasted only about two minutes.
"Is there no known cause for the formation of the fog caves?"
"None." Li Changfeng shook his head, "The term 'Extraordinary Curse' is our collective name for this kind of mysterious natural disaster. Its formation process might actually be very complex, but who really knows so much?"
