The cave on the continental shelf was not a straight path inward.
Under Wizard Ronald's magic vision, the numerous shellfish embedded in the cave walls shimmered, guiding him along the path like scattered crystal lamps.
He navigated around four sharp turns.
Then, after about seventy meters of straight passage.
Wizard Ronald stepped onto the fine-textured wall within the water, and with a push, he propelled himself along this path.
And then...
Then came the sudden, astonishing discovery!
After traversing the cave, Ronald found himself directly beneath Springs.
In this place,
an immense underground cavern stretched out as far as the eye could see.
Though completely submerged, the space was certainly vast enough to house a city!
Thump, thump—
At that moment, the familiar current appeared again.
And unlike the sporadic streams in the ocean outside,
deep within the underwater cavern, countless currents erupted, causing turmoil in the flowing waters of the entire space.
