章 871: Evil Demon Island

Whoosh whoosh!

A ship was speeding across the sea.

Even without its sail raised, its speed was phenomenal.

There were many secrets to treasure maps. A particular symbol, a few lines of poetry, or a riddle could all be crucial clues. They could even be the key to finding the treasure.

The treasure map of the Soro Pirates was no different, and it hid many secrets within.

One of which was a few lines of poetry in the bottom left corner. Coupled with the sea route, the map revealed an undiscovered current.

Of course, it was a stretch to call it undiscovered. At the very least… the Soro Pirates had learned to make use of it.

"The region we just passed had numerous fatal hidden undercurrents. Normal ships go to great lengths to avoid it… Who would have thought that someone could pass through it completely unharmed by riding this current?" Blackbeard exclaimed.
