Among these promotion rewards, quite a few are things Akihara Kagura can already use. Right now they're basically just strengthening some of his former abilities, like the Woods-Woods Fruit, the Mag-Mag Fruit, and the Ice-Ice Fruit. As for the Smoke-Smoke Fruit's ability, he hasn't seen any real use for it yet…
The Future Perception of Observation Haki and the enhancement to Armament Haki are also better than nothing for Akihara Kagura's strength. Even though there are quite a few powerhouses in this world who can foresee the future, they still can't change their own fate.
By comparison…
This Great Buddha Form is really quite interesting.
Back in the Ninja World, Akihara Kagura once developed a terrifying Ninjutsu that could create a Great Buddha several thousand meters long, but it required an insanely difficult level of Hand Seals…
But now…
Akihara Kagura can easily do all of that using the Mythical: Great Buddha Form. His Life Energy far surpasses that of the other user of this Mythical Fruit, Sengoku the Buddha.
Among these rewards…
The most useful one is probably the powerful training effect brought by the Press-Press Fruit.
Akihara Kagura can, without deliberately controlling his power, directly increase the gravity on his own body—say, dozens of times or even a hundred times. It's like carrying several tons of weight at every moment, constantly tempering his body.
"Sengoku called to ask about your training."
An old man with purple hair walked over. One of his arms was a mechanical arm, and there was a gentle, kind smile on his face. "Looks like you've taken my advice and started relying less on your Logia-type Devil Fruit Ability…"
It was Zephyr, the officer in charge of the Navy's training camp.
This former Admiral of the Navy Headquarters was already old, and with his arm crippled, he'd long since been confined to the training camp, instructing the new generation of the Navy.
As a Vice Admiral, Akihara Kagura was naturally different from those new-generation Navy recruits. At the very least, he didn't need to go to the training camp. He even had a training field of his own, and if he wanted to learn the Six Style or train his Haki, he could get Zephyr's personal guidance.
"No matter how strong a Devil Fruit Ability is, it'll eventually meet its natural enemy."
Akihara Kagura nodded, clenched his fist, and spoke calmly. "Besides, even if I keep developing my Logia-type ability, I might not be able to defeat the Konoha Pirates. There was never anything wrong with your guidance, Zephyr-senpai…"
The most important point…
Is that he's not actually a Rumble-Rumble Fruit user.
"How's Karin's training progressing?"
Akihara Kagura casually asked about his subordinate.
As Akihara Kagura's subordinate, Karin naturally got promoted as well. Her promotion speed was just as astonishing; she's currently been elevated to Lieutenant Colonel of the Navy Headquarters.
"Lieutenant Colonel Karin, huh?"
Zephyr couldn't help but chuckle and praise her. "Neither Aine nor Shuzi is her match. It's not often you see someone reach this level at seventeen…"
"Alright."
After finishing the small talk, Zephyr took the initiative to bring up business. "Sengoku called to ask about how you're doing. I've also heard some things about Headquarters. He should already be out of usable people over there, to the point he's almost eyeing this retired old man…"
"Has something happened?"
Akihara Kagura felt there shouldn't be any major problems.
The historical truth behind the Alabasta incident has already been officially recognized. Most of the Heavenly Celestial Dragons' corpses from the Mary Geoise incident have already been buried. The aftershocks of the Sky Island incident are still exploding. The Heavenly Celestial Dragon slave auction hasn't officially begun yet. He's been burying himself in training here and hasn't issued any orders at all. What big trouble could possibly stir up on this sea?
