"This—this is incredible! Magnetic pointers, whether Log Poses or Eternal Poses, will all be rendered obsolete by this thing! Lick~"
Perospero, the eldest brother, was the first to realize this thing's immense value. Even amid his shock and excitement, he could not help but sigh inwardly.
He was already twenty-six as the eldest brother, yet he had not come up with a single respectable invention. Mousse, not even seven years old, had already created a great invention capable of changing the entire world.
Was the gap in talent between people really this enormous?
The chaotic magnetic fields of the Grand Line severely affected the accuracy of magnetic pointers.
Especially in the New World, where common sense was overturned, navigators had to rely on their experience and intuition during voyages to pick the direction closest to correct from the conflicting readings of several pointers. Often, they were not even as useful as Life Cards.
But the gyroscope Mousse had invented was different. Since the gyroscope's orientation never changed, no matter how chaotic the magnetic field was, it would not suffer the slightest interference.
Once it was widely adopted, shipping efficiency on the Grand Line would surely undergo a qualitative leap!
And in a world centered around oceanic civilization, improving shipping efficiency meant far more than merely saving freight costs!
However, Mousse's direct purpose in inventing this device was to use it for straight-line voyages and determine the true, accurate distances between islands.
Previously, during voyages through the New World, navigators had to constantly correct the magnetic pointers' directions according to their experience and intuition. The actual routes were therefore not fixed straight lines, but irregular curves that differed with every voyage, making it impossible to accurately measure the true straight-line distance between distant islands.
So, alongside the gyroscope, Mousse had equipped
