The meeting with the Martial Union lasted long as Rui addressed the many problems that had emerged as a result of the war. The sheer amount of economic, political, and logistical problems that had emerged as a result of the third Great East Panamic War was a lot. After all, as a commercial Martial broker, the Martial Union was sensitive to market shocks that had happened as a result of supply and demand disruptions in the economy.
Nonetheless, Rui provided them with the best solutions then and there with his sheer political acumen.
He was not nearly as much of a whizz as his father was, of course. But, given that his father was extremely busy as the Emperor of the Kandrian Empire, he didn't have time to look after the Martial Union at this time.
On top of that, the Martial Union was too proud to ask him for help.
Thus, Rui had no qualms about offering fixes to the various problems brought up.
