Treasure Hunting Series

The primary character of the series is the young but precocious Pang-Yi who accompanies his uncle, the Professor Gu-Bon, on various foreign trips for historical studies. They encounter a clue to a lost item, and the hunt would take them across the country, bringing them to sights and experiences significant to said country. Pang-Yi's rival is Do To-ri, a child prodigy, though they are willing to work together occasionally.
