"Finally, it's over. When will the World Government deliver those 131 Devil Fruits?"
Hades was speaking to his wife, Metis, over a video call.
Metis had been especially busy lately. As Hades's wife and chief administrator, she was helping him assemble a Cabinet to assist with the Kingdom's affairs.
She also had to oversee the Kingdom's development across every sector.
And she had to keep an eye on the negotiations with the World Government.
By comparison, Hades's workload was hardly worth mentioning.
Once Hades had a solid grasp of the Kronos Kingdom and the Cabinet was in place, he would naturally have more free time again.
Besides, he had no intention of devoting all his energy to government affairs. Improving his own strength remained his most important task.
At twenty-eight, Hades had yet to reach his peak.
Training did pay off.
Wearing high-concentration Seastone Handcuffs, he dragged Warships through the sand.
As the number of Warships increased, he could clearly feel every part of his body growing stronger.
And now, Hades had another piece of Black Technology that could make his training more effective.
A gravity field.
Gravity was something Hades had long asked Nikola Tesla to study, hoping he could find a way to control it artificially.
With enormous funding behind him, Tesla had clearly succeeded.
The New World's unpredictable conditions and countless unusual magnetic fields had created its extraordinary islands and wonders of the sea.
Gravity Island was one of them.
The islands' strange magnetic fields gave them highly unusual gravity.
Some gravity islands had up to ten times normal gravity.
Others had gravity weaker than normal.
Some unusual floating islands stayed aloft for that very reason.
By studying the magnetic fields of these gravity islands, Tesla had developed a device capable of creating a gravity field.
He
