章 233: The Ancient Ruins

The more eastward they went, the thinner the mist became. But the sky was still darkened, as if the sun could not shine in these waters.

In addition, the surrounding reefs were becoming higher and higher, turning into sturdy stone pillars. Somehow, though the water line was declining, the ship still sailed at a steady speed. Even the waves became smaller and the sea was as tranquil as a windless lake.

Tilly asked puzzledly, "Why not enter the Shadow Islands waters after waiting for the seawater to completely recede? Once the reefs are exposed, you won't be afraid of crashing into them."

"Because before the seawater recedes, we can see the Ghost Shadow Red River, which is the only way to lead us to the ruins," Thunder explained. "The locations of these pillar-like islands aren't stable, and vary from each ebb and flood tide. Besides, most markers would be flooded so that they can't be used for positioning."

"The Ghost Shadow... Red River?" She repeated.
