The team's attention refocused on the mysterious coin.
Mike brought his attention back to the nautical chart, "There's still one problem, the map on the coin is too simplistic."
"Los Haitises National Park covers such a vast coastline, with hundreds of islands and caves, we can't search one by one, can we?"
"Of course not." Lin Yu'an smiled, once again picking up the coin and a magnifying glass.
"Our pirate friend is far smarter than we imagined. The clues he left behind are not just a map."
He focused the magnifying glass on the edge of the miniature map, pointing at several nearly indistinguishable symbols, letting the two look closely.
"This doesn't look like a latitude and longitude," Riven said, "more like some kind of... encryption?"
"Exactly." Lin Yu'an nodded, "These are not geographical coordinates but a series of cipher symbols integrating alchemy, astrology, and ancient navigation skill."
