Before sharing his experience with the old man, Roland went back to the hotel and cast onto Betta and the others another Unhindered Communication.
He also told them that he was going to pick up some knowledge and magic insight, and might not return to the hotel any time soon, so if Unhindered Communication failed again, Betta could cast Language Proficiency to help out. Although they wouldn't be able to read, basic communication wouldn't be a problem; just the speed of information gathering would drop a bit.
Everyone expressed that they understood.
Knowledge was a Mage's second life—everyone knew that.
Li Lin bantered, "Is it a beautiful teacher?"
"It's an old man," said Roland, smiling, "but he has a very beautiful granddaughter. Would you like to be introduced to her?"
