At the junction of the Red Line and the Grand Line—Reverse Mountain and Mary Geoise—the highest point was only a little over ten thousand meters.
Even factoring in the diagonal distance, World could bombard the Holy Land directly from beyond ten thousand meters away.
And that was only the minimum. If the cannon itself was extraordinarily powerful, that range could increase geometrically!
At the same time, that raised another question: how many times could that cannon fire?
Once, twice, three times?
Or endlessly?
"So the key to this battle isn't defeating World and Redfield, but figuring out how to destroy that massive cannon."
As soon as those words were spoken, everyone fell silent.
They all understood the logic now, but there were far too few ways to put it into practice!
After all, those were the two monsters. Their submarines would be detected through the seawater before they could even get close, then picked off and blasted apart one by one.
The Airship Force had suffered even worse than the Submarine Force sent from G-5. Unless they climbed to an altitude of ten thousand meters, the dense anti-aircraft batteries would teach them what firepower suppression meant.
World clearly wasn't some reckless brute. Knowing the Navy's current military strength, he had comprehensively modified that giant ship specifically to counter every method the Navy possessed. Who knew where he had gotten so much money?
"Can we use Railguns to establish a crossfire network and launch a concentrated strike?"
Chaton's suggestion suddenly lit up everyone's eyes.
Since close-range bombing and sabotage had been countered, the Railgun's range and destructive power could allow them to launch an over-the-horizon strike from beyond the enemy's field of vision.
Ron pondered for a moment, then nodded.
"This is similar to the over-the-horizon lightning bombardment I use. It's
