The furrows in the ground were tracks left by dragging warships.
The stronger one became, the less effective ordinary training was, so methods that pushed people closer to their limits were needed.
Ever since Hades and Titan first joined the Rocks Pirates, training with the immense weight of warships had been part of their daily routine.
After the Pluton Pirates were founded, their growing number of warships made this a training method for the crew as well.
