This was definitely the spring of King Rachi, as well as Argyll's big break! If Argyll made full use of this opportunity, he could soar to fame easily, just like the carp, which transformed into a dragon upon jumping over the dragon's gate!
Argyll, who had seized control of the finances, was like an athlete who had been injected with 50 amphetamines. The immediate unleashing of his potential was so great, even the lord would be astonished.
Regarding any need for sleep, as a Magic Caster of great ability, Argyll thought he could pull three all-nighters without any problem. Gold ingots were readily available, but not silver ingots. As such, he could get the goldsmiths to immediately melt all the silver coins and command the local skilled trade caravans to go out and collect silver coins of other tribes.
