"Lord Sherlock, you are saying that your friends are archaeologists and want to participate in the archaeology work?"
The Gnome shopkeeper hesitated for a while as his long green fingers tapped on the table.
"Yes, exploring the ruins carries certain risks like traps and Magical Beasts. Without experienced archaeologists, it's easy to have accidents. To gain access to the ruins requires professionals."
The Gnome nodded and said, "Unfortunately, this matter was already taken up by the Merchant Alliance."
"I understand, I have seen it on the small pamphlet. The Merchant Alliance is wary against superior Devils. If I recommend someone, the Merchant Alliance will most likely decline them. Why don't you handle the recommendation? As a Magical Item expert, a Merchant Alliance member, and even the discoverer of the Ancient Ruins Key, if you strongly recommend someone, they will agree."
