Bang.
A dull sound was heard.
The door to the Fleet Admiral's office was violently pushed open.
The hand of Sengoku, who was inside processing documents, immediately jerked. A long diagonal line appeared on the file on his desk.
Veins bulged on Sengoku's head at an extremely fast speed. Anger instantly flooded his eyes. He looked up sharply.
"Gar..."
His shout stopped abruptly.
Sengoku stared blankly at the person who had entered, his brow furrowing tightly. He asked uncertainly.
"Zephyr?!"
Even though it was impossible for Sengoku to mistake the appearance of the person who entered, he still wasn't entirely sure.
Theoretically speaking, this kind of violent door-breaking behavior should only appear with that old guy Garp.
When did Zephyr become like this too?
No way!!
One Garp already put a lot of pressure on his door. If he had to deal with Zephyr too...
Would his door even survive?
Before Sengoku could speak, Zephyr's voice came over.
"Sengoku. Hand over your grandson to me. I will definitely train him to become the strongest Marine."
???
(⊙o⊙)?
Sengoku was bewildered, very bewildered.
Wait, what kind of nonsense is Zephyr spouting?
Is there something wrong with his mind?
Could it be...
"Don't even think about it, you old fool. I am talking about your grandson. Kyle."
"I want to be his teacher. I will absolutely make him the strongest Marine I have ever taught."
Excitement and enthusiasm shone in Zephyr's eyes.
He had held the position of Head Instructor at the Marine Elite Training Camp for many years.
If you asked who in Marine Headquarters was the most qualified to speak about potential, it would definitely be him.
And he had just seen that extremely powerful potential in Kyle.
It wasn't the fruit ability that radiated an aura of ultimate destruction.
It was the incredibly powerful physical potential.
Don't ask how he could see it.
He could see it, that's all.
As a Marine of the older generation, Zephyr placed more importance on physical prowess than on Devil Fruit powers.
Therefore, regardless of which students he faced, he emphasized that physical strength was the most important.
But this wasn't to say Devil Fruit powers were weak.
On the contrary, Devil Fruit powers were strong, very strong.
Especially powerful Devil Fruits. They could greatly enhance the user's strength.
Looking at all the students he had taught, three students stood out the most.
And they were all Logia-type Devil Fruit users.
Among them, two students had already become active Marine Admirals. The other student would probably achieve the same in just a few years.
At that time, his position would most likely be taken over by that student.
So, he never believed Devil Fruits were weak. It was just that in his view, one should not rely too heavily on fruit abilities.
The combination of fruit ability and physical ability could create the strongest, all-around, six-sided Marine.
In this regard, Kuzan and Sakazuki had done quite well. They did not abandon training their own bodies while developing their fruit abilities.
In contrast, the oldest, Borsalino, relied too much on his Pika Pika no Mi ability and neglected physical training.
This was also the reason he felt somewhat displeased with Borsalino this afternoon.
The two of them really didn't see eye to eye.
This was normal. Even if a student's ability was strong, if they didn't listen to the teacher and were a troublemaker, the teacher couldn't possibly like them.
He could see that Kyle's fruit ability was very powerful. That ultimate aura of destruction made even him feel a slight tremor.
If left unchecked, he feared Kyle might walk the same old path as Borsalino, focusing too much on developing the fruit ability and neglecting his physique.
This he could not allow.
To him, Kyle was now like an uncut piece of fine jade. He absolutely could not let it be ruined.
He couldn't control Borsalino, so be it. That perverted guy's physical potential really wasn't that strong anyway.
He had said his piece. Whether you listened was your business.
But Kyle was different.
Such formidable physical potential had to be taught by him. Only he could teach Kyle properly.
Seeing Sengoku still looking somewhat bewildered, not having regained his composure.
Zephyr frowned and spoke another sentence.
"I'm only informing you because you're the kid's grandfather. This is not a request."
"Kyle must be my student. I said so, and no one can stop it."
After saying this, Zephyr turned to leave.
"Wait."
Sengoku's voice came from behind.
Zephyr turned around. What met his eyes was Sengoku, his brow tightly locked.
"Are you sure you're talking about my grandson, Kyle? And not someone else with the same name?"
"I wouldn't fail to recognize your grandson."
Sengoku's frown deepened.
His grandson. Become the strongest Marine.
What a joke.
What level his own grandson was at, wasn't that clear to him, his grandfather?
Before Sengoku could speak, Zephyr continued.
"Your grandson's lightning ability is very powerful. Regarding the development of fruit abilities, I admittedly don't have a deep understanding."
"But at least I can guarantee that regarding physical prowess, I will absolutely fully unearth your grandson's physical potential."
"So..."
"Wait."
Sengoku interrupted Zephyr. His eyes widened larger than brass bells.
"What did you just say?"
"My grandson's lightning ability? When did he eat a Devil Fruit? How come I don't know about it?"
"You don't know?"
This time it was Zephyr's turn to be shocked, followed by a look of disdain.
"What kind of grandfather are you? You don't even know your own grandson's situation."
Sengoku forcibly suppressed the shock in his heart. His gaze fixed on Zephyr.
"You saw with your own eyes that the kid Kyle has a Devil Fruit ability?"
"Of course. Right at the back mountain. I just saw it."
Sengoku fell silent. After a long moment, he suddenly stood up and walked towards Zephyr.
"Come on. Lead the way. Let me see it with my own eyes."
...
On the other side, on the back mountain.
With continuous training, Kyle's mastery of his fruit ability improved somewhat.
The number of times he crashed into trees had decreased noticeably.
Every time the purple lightning flashed, Kyle's figure would instantly vanish, then appear dozens of meters away.
Lightning is light speed. In terms of speed, it's not inferior to the Pika Pika no Mi.
Moreover, its flexibility is higher than light. It can curve. In other words, it can turn, unlike Kizaru who needs to reflect to change direction.
Before obtaining the system, he had thought about learning Soru from the Marine Six Techniques once his physique got a bit stronger.
Now it seemed that wasn't necessary.
No matter how fast a physical burst could be, could it be faster than lightning.
As for the other Six Techniques, Kyle had no interest at all.
Especially the technique known as the 'Strongest Defense', Tekkai.
Kyle thought people who practiced this technique must have something a bit wrong with their heads.
Faced with an incoming attack, the first reaction wasn't to dodge, but to shout 'Tekkai' and then stand there passively taking the hit.
It was a bit too abstract.
"Kyle."
At that moment, a familiar shout came from not far away, causing Kyle, who was practicing, to stop his movements. He turned his head to look in the direction of the sound...
