To reach Lutom Island, they first had to cross mountains and rivers. Among the party of six people and one dog, the one most familiar with the way was undoubtedly McBain, who had traveled this world more than once.
He told them, "To get to Lutom Island, we must first pass through these winding mountains. There are even deep, dark caves within them. Taking the mountain paths would be time-consuming and exhausting, but there is almost no light inside the caves, so every step we take will be difficult."
He continued, "This cave is called Water Harp Cave. Its only advantage is that I have passed through it before. I know what every spot where water drips sounds like. As long as we listen to the sounds and proceed slowly, we will definitely be able to find our way out."
Uchiha Madara suddenly said, "A cave like this seems like an excellent place to hide something. Should we check whether the magic map shows a Resonance Stone buried here?"
McBain froze when he heard Uchiha Madara's words. "Look—there really is one!"
Everyone crowded behind McBain and saw that there was indeed a point of light at the location of Water Harp Cave on the magic map!
Moreover, the magic map itself seemed capable of storing light energy. The point of light was fairly bright, and though Water Harp Cave was indeed exceedingly dark, it still allowed them to barely see the road.
Thus, under the illumination of that tiny point of light, they slowly made their way through Water Harp Cave. They heard the steady dripping of water, with flowing water beneath their feet, while McBain walked at the very front like a qualified guide.
"Here—do you hear it?" McBain suddenly stopped walking and said.
"What?" everyone asked in confusion.
