Seeing the puzzled expressions on everyone's faces, Qian Luo patiently explained, "The cloud qi surrounding that city was somewhat special. After thinking it over carefully, I remembered that I had seen this type of cloud qi in the 'Ancient Array Hundred Solutions Map' of Bilun Continent."
The Ancient Array Hundred Solutions Map is an ancient manual of arrays from Bilun Continent, which is more completely preserved compared to many inheritances of the Human Race and Beast Race.
It records many arrays that have been lost on Canglong Continent.
After Qian Luo mentioned this, everyone then recalled that the surroundings of the Four Symbols Chess Middle City did not display any special geographic features such as green mountains and clear waters or azure seas and blue skies; instead, it was surrounded by clouds and fog from beginning to end, making it seem as though Four Symbols City was floating in the air.
