章節 509: Chapter 298: Inverted World_1

"A vortex?"

At that moment, at the front of Skeleton Island, Mu You encountered the same situation as Jack.

"How could a vortex appear in such a place?" Lin Xue, looking at the massive sea vortex ahead, was also somewhat astonished.

She didn't have extensive knowledge of oceanography but knew that sea vortexes usually form where currents intersect. As for this calm and windless sea suddenly forming such a large vortex, it was too abnormal.

"The course isn't a problem..."

Mu You inspected the orientation of the compass he held in his hand. As the ship swam around the perimeter of the vortex, the needle steadily pointed to the center of the vortex.

"Which means, the entrance is probably within this vortex..."

"Would the entrance to Sky City have such a clear sign...?" Lin Xue asked. To prevent Sky City from being invaded by other factions, they should make the entrance very hidden. Yet the giant vortex now was too conspicuous. Any creature nearby could see it.
