There were very few things that required Kant to personally handle at the central posthouse.
Basically, Rolf would handle it.
As for roping in the merchants...
Manide, who came from a merchant family, had more to talk about with these guys.
In fact, when Kant led his team and left, the table salt trade had already begun. Those merchants from the Dukedom of Leo, who had the support of various noble families, all had a good exchange with Manide.
This was a good impression that they had cultivated previously, especially with Rolf's foil, Manide was even more welcomed by them.
At the very least.
Manide would not get angry over a certain sentence.
Although he was more difficult to deal with in business exchanges, he abided by the rules.
For example, Rolf, this scoundrel noble, did not care about the business rules. If he dared to say anything bad to him or find trouble with himself, then it would be a knife fight.
