"Your subject thanks Your Majesty!"
Arranging for him to study in Black Moon City had been agreed upon long ago, so Karl was not particularly surprised.
Meanwhile, as Zhou Xu spoke, his gaze rapidly swept over the resource list Karl had presented. It mainly consisted of mineral resources.

His attention immediately focused on the special ores.
These special ores had never appeared on the trade lists before. They had been considered non-sale items.
