Ink Orchid isn't completely clueless about numbers.
The caravan can sell Ghost Fan Seed Pods for 25 Source Stones, but buys them for 18, so that's a difference of 7 Source Stones per pod.
Ink Orchid asked, "Dragon Cypress, one Ghost Fan Seed Pod makes 7 Source Stones of profit, how much if we have 637 pods?"
Dragon Cypress: "You can't calculate it like that."
Dragon Cypress asked, "After collecting them, who do we sell them to? The caravan? If the caravan asks where you got them, how will you explain?"
Ink Orchid: "Uh…"
Right—Ink Orchid, who'd just lifted her head in excitement, drooped it, crestfallen.
