The Crystal Ship advanced across the water.
One thousand meters, two thousand meters, three thousand meters...
Gradually, the lakeshore vanished from sight, surrounded by endless water.
Hulk continuously output energy to propel the Crystal Ship forward, occasionally assisted by a few of Moli's other men, but Hulk was the main force.
After traveling like this for half the day, the Crystal Ship in the underground lake had no idea how far it had gone, and there was nothing for those on board to do, leaving them bored almost to the point of sleep.
Just then, a dull "bang" sounded from the bottom of the ship, as if it had hit something, causing the Crystal Ship to lurch and abruptly slow down.
The people on the ship snapped awake from their drowsy state and all looked at Hulk, quickly asking, "What happened? Did we hit a reef?"
