Yan Xing wasn't merely speculating about the Orc Treasury. Real-world precedents supported his theory. Intelligence transactions never involved credit; there had to be an underground bank capable of quickly providing funds as needed. Heavy rewards bred brave men. The mercenaries serving the Orcs were so active precisely because they were paid well. Moreover, this world had neither paper currency nor bank transfers; they were paid with tangible gold. An excess of this gold stored anywhere in the Wildwind Highlands would be dangerously conspicuous. Only Nuta City could conceal it under the facade of bustling trade.
Therefore, Yan Xing found himself an excuse to investigate "Shortgun." Finding the Orcs' private treasury would be ideal. If not, at least he could get Li Jiya off his back. This girl... is a bit clingy! I have so many matters to attend to every day; I can't always be here putting on a show with you.
