"Teigu: Godfather's Majesty—Flame Tank!"
"Secret Technique: Overwrite!"
At the same moment Big Father Castle entered "War Mode, All Guns."
An invisible Teigu power spread through its interior as crimson light.
In the blink of an eye.
Every cannon muzzle lit up with ominous dark-red gleams.
This multiplied the already terrifying power of the shells several times over.
They were using super gunpowder provided by Tengen Uzui, optimized by Buggy, and further improved by Flam as the director.
It had to be known that only around thirty percent of the gunpowder used by Nuclear World and State Religion World could be converted into kinetic energy.
Meanwhile, the super gunpowder now used by the World Government had reached a conversion rate of seventy percent.
Capone Bege further amplified it with Teigu on top of that.
But this still was not his limit. His voice rang out again.
"Armament Haki: Hardening!"
Jet-black streams of light covered every large-caliber shell about to be fired like living creatures.
Granting them unparalleled hardness and penetrating power.
It was not over yet.
"Flame Breathing: True Technique—City-Burning Purgatory!"
This time, Capone Bege drew upon the natural energy in the air.
He extracted the fire element that had been generated in massive quantities by the earlier bombardment.
The war fortress known as Big Father became completely engulfed in soaring, blazing flames.
The terrifying heat warped the surrounding air in an instant.
At the same time, every cannon barrel and shell within was coated in another layer of brilliant flame.
One could only imagine how much its power would surge again.
At that moment, Capone Bege's Big Father Castle was like a fiery god of war from purgatory.
If he were allowed to slaughter freely in Nuclear World now.
He was fully capable of bombing every nation into barren wasteland.
