"This island is home to a tier one monster beast known as the Red-beaked Sparrow. This beast isn't very useful, but the eggs it lays are quite delicious! They're considered a specialty here!"
"There's a type of small fish in the sea known as the Black Shuttle that loves to eat the droppings of these birds. They usually gather near the island, and when the waves roll in, they look like a black tide. Hence, the name Black Tide Island."
As the island approached, Xu Yiren started explaining to Xu Mu.
As their flying boat drew near, Xu Mu saw that the black waters, indeed, consisted of thumb-sized black fish gathered in large numbers.
Closer to the island, there were groves of red trees, half growing in the water, half in the sea.
Gray-feathered and red-beaked small birds lived in these red forests.
These should be the Red-beaked Sparrows Xu Yiren was talking about.
The flying boat didn't halt at the edge of the island but headed straight toward the center.
