There was nothing special about the middle-aged American couple.
The man was dressed very ordinarily, and his appearance was also very ordinary. Even the luggage he used was extremely ordinary.
But in the middle-aged man's hand was a folding fan that attracted Ye Feng's attention.
Ye Feng did not even need to activate the system's deep navigation, he could tell that this folding fan was not ordinary.
Just as he expected, a message popped up after he activated the system's navigation.
[Tang Yin's folding fan, authentic. The fan surface is "Talking about the Ancient Times at the River Pavilion." It's worth about 130 million.]
Ye Feng's eyes moved again.
Tang Yin was Tang Bohu. In China, it could be said that everyone knew him.
The fan was made by one of the Four Great Talents of Jiangnan.
