The other Golds also had their own agendas.
Olga and Otto, for instance, were looking for business. It was just their instinct. Even if they didn't have Bleulle as a market, the human territory was so vast. The region Bleulle controlled was only a tiny part of it.
In contrast, the ever-optimistic Otto just thought it was finally his chance to explore more places. Maybe he could go northward or eastward for the second half of his life. He had always been travelling around Bleulle and just a little beyond it. After all, there were already plenty of territories there that could eat up his stocks even if he charged a lot for them.
In any case, Otto was particularly interested in the long-term food factories. Although he had bought a lot while in partnership with them, he knew there were still plenty of things he hadn't seen.
Anyway, after a day or two of waiting, he finally received a clearance for a factory tour.
