The City of Southern Zhou is located in the southern province and has an exceptionally large land area with a dense population. Being situated at the southeasternmost part of the Saint Dragon Continent and far from the political center, the local customs here are relatively fierce; nearly everyone practices martial arts, and each person cultivates their qi.
Indeed, due to its proximity to the sea, Sea Monsters often cause chaos, so the people here place great emphasis on their own training. Even the common porters in the mountains have surpassed the Truth-Insight realm, and even small street vendors have reached the level of Foundation Establishment.
As such, the best-selling items on the main streets are also weapons, elixirs, and cultivation manuals.
Of course, those so-called cultivation manuals are only the lowest-level qi-cultivating methods, after all, no one would actually sell their real secret techniques.
