After watching for so many days, and with Kuro and Lida explaining the principles from time to time, he, who had practiced the Six Styles, naturally learned this 'Nail Fist Technique' as well.

The only advantage of this boxing style, in his view, is not 'concentration,' but rather the 'dispersion' after 'concentrating' force. For those of them who lack AOE (area of ​​effect) methods, this is a close-range AOE technique. Combined with his own speed, it is just right for clearing out mobs.

Having just delivered the first blow, Kuro stomped his feet on the ground repeatedly, using 'Shave' to appear behind Kuro. He stretched out his legs and kicked forward, slashing out like a crescent moon, creating a massive half-moon slash.

"Storm Kick - Rainstorm Gun".

The slash from the storm kick suddenly dispersed the moment it was launched, transforming into a dense barrage of spear-like attacks that struck the black-clad men wielding straight swords.

Sizzle!

The black-clad men surrounding the navy were pierced by the slash, and one by one they fell to the ground, stained with blood.

Kroh pulled his legs back, silently adjusted his glasses, raised his head, and said disdainfully, "A bit weak."

As soon as he finished speaking, some of the men in black with straight swords stood up again, gripped their swords, and continued to slash at Lida.

"Can't you hear me?"

Kro kicked out again, his kick exploding and hitting the men, worsening their injuries.

"What happened?"

Kro's expression turned somewhat grim.

These people were hit by two of his moves, and both were quite powerful, rendering them unable to move. Even so, none of them lost their will to fight. Even though their bodies were immobilized, those who could still use their hands still gripped their straight swords and slowly moved their bodies toward Lida.

The feeling was like a robot that was programmed so that no matter what external force was applied, it would not change its target.

At the same time, their eyes remained unchanged, just like that straight knife, straight and sharp.

"This is ridiculous... Let me see your faces!"

Kro stepped on a straight knife that was swaying forward and bent down to lift the man's black mask.

It was a normal human face, but expressionless. Even though it was pale from blood loss, there was no change in its expression.

Click.

The straight sword beneath his feet seemed to have snapped in two as he stepped on it, perhaps because it had just been used to defend against Kro's attack. At the same time, the man's pupils gradually dilated, his body stiffened, and he stopped moving.

He wasn't dead; he still had a life force, but he looked like a dead person.

This made Kuro frown. This was a living person; there was no mistake.

The idea that weapons can turn people into humans is nonsense. Just take it as a joke. There aren't enough Human-Human Fruits to feed so many people who use straight swords, and it's impossible for all Human-Human Fruit users to be 'human' beings.

The concept of 'human' doesn't apply to that reindeer; there isn't a single Devil Fruit that's exactly the same.

This is what people are like; although they are a perfect match for their knives, they are undeniably human.

Kuro walked over and lifted the mask off another man in black. The face that was revealed was different from the previous one, except for the eyes.

And eyes are the windows to the soul; it's not difficult to make them look the same.

Kuro knew that Kas could do it.

"A fruit with strong infectious properties? Or perhaps..."

Kuro picked up the straight sword. As soon as the sword was in his hand, the man in black below began to struggle violently, even though his hands and feet had been injured by Kuro's kick.

"The material is very hard..."

Kuro glanced at him, flicked the blade with his finger, and said calmly, "The aura is like a sword. If it's too rigid, it's easy to break. A sword can be repaired if it breaks, but if a person breaks, then that's it."

He loosened his grip, and the straight knife plunged into the ground. The black-clad man below grasped the blade, blood seeping from between his fingers, but he didn't care at all. Only by holding the knife did he stop struggling violently.

"It's not a compatibility at all. You people are just slaves to weapons."

Kuro understood. Neither this black-clad man with the straight sword nor Gadi with the long straight sword was a 'man-sword unity'. They were simply slaves to their weapons, and their personalities and attacks were aligned with the weapons, which is why they were so well-matched.

It's not that people wield the sword, but that the sword wields people.

Moreover, it seems that Devil Fruits alone are not enough to achieve this level of skill.

Kuro turned on the Den Den Mushi and dialed Sentomaru's number.

"Brother Kuro?"

After a series of rings, the Den Den Mushi transformed into the form of Sentomaru.

"Let me ask you something. You're Vegapunk's bodyguard captain, right? Did that guy ever research any kind of technology that matched weapons to people?"

"Weapons and people?"

Sentomaru paused for a moment and asked, "You mean 'life factor'? That bastard Punk seems to be researching this, but he probably doesn't have time lately. It seems he's researching... Ah, I can't say. Sorry, Brother Kuro, I'm the most tight-lipped man. No matter how you ask me, I won't tell you that that bastard Punk is researching the secret weapon 'SSG'."

“It’s not ‘life factor,’ I know that stuff. Also, Sentomaru, you’ve revealed the secret.”

"ah..."

The Den Den Mushi's eyes darted around a few times before it said firmly, "That's what I wanted to say. I won't tell you the rest of the secret, so don't ask anymore, Brother Kuro."

"Fine, fine, go play with your axe by yourself."

Kuro hung up the phone and exhaled a puff of smoke.

SSG?

What is that thing?

Is this true?

Isn't the world government's latest weapon the 'pacifist'?

Although he didn't know what it was, Kuro wasn't interested. He thought for a moment and asked the lieutenant next to him, "Whose jurisdiction is this area?"

“Lieutenant Colonel, this is a neutral zone, not under our jurisdiction. The two kingdoms nearby, though close, are actually located on two separate flight paths.”

“The waters near the kingdom of ‘Ruoman’ to the west of Meng Island are the G-8 branch. The kingdom of ‘Suknai’ to the east is on another shipping route, and there are no directly subordinate branches nearby, only some bases,” the lieutenant said.

"Not only is it a neutral zone, but it's also a no-man's-land, yet it has managed to maintain order?"

Kuro glanced at the group of men in black below. "Is this all you're relying on? Or is it..."

He looked at the huge fortress at the very top of the island. "That must be where Lord Meng Island lives. It will take until the magnetic field is fully charged, right? Then let's go and bother him. We are an official organization, how can we not contact the local master?"

"Lieutenant Colonel, it seems that Sir Mengdao doesn't welcome the Navy. If we go there rashly, will we..." the lieutenant said hesitantly.

“What kind of people don’t welcome the Navy? Tell me?” Kuro glanced at him.

Only criminals would dislike the Navy.

Coincidentally, Kuro had just activated his Observation Haki. Although the fortress looked very sturdy, there was a great deal of life energy inside, and it was incredibly diverse.

Just like the diversity of weapons...
