The Demon Control Area, which hadn't welcomed an official merchant caravan for a long time, had finally received its first batch of merchant caravans... The previous ones from the Silver Moon Tree Court and those expensive war traders couldn't be counted as official caravans.
This caravan from the empire had formally submitted documents to enter the Demon Country, although the documents still didn't use the more formal term "Demon Control Area" and instead chose "Demon Country."
But it still didn't prevent the Demon King's territory from selling blue qing mushrooms to these caravans.
As of now, the specialty of the Demon King's territory was the blue qing mushroom. This quite special crop was indeed very popular in various countries around the world... although Yila hadn't eaten much of it before.
It could also be that he hadn't paid much attention to it.
