Upon seeing the dumbfounded look on the tribal Conqueror's face, Tugra replied respectfully, "Great Conqueror, the sea chart is filled with text and symbols that have become incomprehensible while soaked in the sea. The overall outline is like the one you hung in the treehouse, so I think it must be part of the nautical chart of the Hellfire Archipelago."
"Show it to me right away, Tugra! Bring the chart to me!" Zhang Lisheng said in a hurry.
The sea chart and the nautical chart sounded similar, but in truth, they were different. If the sea chart was equivalent to a rough ocean topographic map; the nautical chart included the ocean current data, the distribution of the reefs, and an encyclopedia of island products of the entire sea area.
