A low and sonorous sound came from down the river, with an octave-low echo, as if a giant beast was forcefully blowing through its nose. I had never heard such a sound before, but Shajina's face immediately lit up with joy: "Ah, we're just in time, the ship has arrived so quickly!" It seems that the sound we heard was the whistle of ships in this world.
A massive silhouette appeared in the distance alongside the whistle. It moved quickly, and it wasn't long before it came fully into view. It was a two or three-decked metal boat, with strange colorful patterns etched on its hull. No sails were visible, but layers of white spray were seen rising at the stern. From afar, I could sense a stable energy source within it releasing energy, which might explain why we didn't see any sails on this wooden ship: it seemed to be driven by magic.
