Normally, selling for 3000 to 4500 golden crowns is quite appropriate. This price ensures that even if the Kingdom Knight's Territory saves up until the end of time, it won't be able to afford a Champion Knight. As for a Baron's Territory, even with a higher tax revenue scale, after covering the huge military expenditure and territory maintenance costs, it would take years, even decades, of fiscal surplus to buy a Champion Knight.
Only in the territory of a Count or a Duke is a Champion Knight relatively easy to come by, and it's only in the Elector's Territory that you can see Champion-level knights serving as Knight Commanders. Su Li had a rough idea of this when he departed from Bauhinia Castle. At that time, he was very proud that the combat effectiveness of the army he had built was already comparable to that of an Elector's Territory; it was just that its scale was equivalent to a small squad of an Elector's Territory.
