In the Owl Magic Shop.
Leonard Churchill and his two companions got several Storage Rings filled with the goods they needed.
Although they bought a lot of items, most were actually classic books passed down from the Royal Academy.
The shopkeeper old lady wore an expression that she was making a losing deal, but for these Black Market shops, such books were the most profitable trades.
Important classic books like the Fifty-two Demonic God Secret Skill were copies—they could be sold once, and then sold again.
It was indeed a business without any cost.
As for Extraordinary Materials and such, Leonard glanced at the merchandise catalog, finding only a few Eighth-Order Materials, none suitable for Sophia Jones.
After all, it was still the Black Market, where many items that should be public are flowing into large commercial enterprises like the Rainbow Consortium.
