Radar Enemy Detection, Pirate Nightmare

Why did the war begin, and why do pirates never cease their attacks?

Our nature cannot be taken away, yet we too have our doubts!

For whom do I clench my fist in anger? I'll beat you to death, you little brat, to rid you of your Inner Demon...

Cough cough cough, I'm getting carried away.

In Roman's view, the world's technology tree was undoubtedly terribly skewed. One could even say that not only the technology tree, but the development of Devil Fruit was shockingly skewed as well.

Everyone is desperately developing their combat skills, but the only one whose 'technology' and Devil Fruit complement each other is Enel and his Ark Maxim.

When it comes to Enel, the first thing that comes to mind, besides his invincible Rumble-Rumble Fruit, is his Observation Haki that covers the entire Sky Island!

In fact, after humbly seeking guidance from Vice Admiral Garp, Roman had gained a certain understanding of the top-tier Observation Haki in this world. Even the top experts could only cover an island with their Observation Haki at most.

If it exceeds this range, it's generally an effect combined with Devil Fruit. For example, a blind person being able to sense near-Earth orbit meteorites using Observation Haki is an effect combined with the Press-Press Fruit.

Enel was able to achieve the godlike effect of "knowing everything that is said" on Sky Island for the same reason, which was the result of the combination of Observation Haki and the Rumble-Rumble Fruit.

Of course, Roman's Observation Haki and Devil Fruit development are definitely not at Enel's level. However:

If you lack the ability, make up for it with technology (and your imagination)!

Within a radius of over a hundred nautical miles of the warship commanded by Roman, hundreds of pure white doves scattered across the sky. To the naked eye, they appeared no different from ordinary white doves, but if Enel were here, he would have noticed:

Each pigeon radiates electromagnetic waves, like hundreds of radars operating simultaneously, constantly scanning and exploring this sea area. The denser they are, the clearer, more specific, and more comprehensive the information they obtain.

"Zhiwu-hanging back to the line!"

That's right, compared to the 'traditional' Observation Haki -based search, this is a more 'scientific' search method.

Using white doves as a 'base station', and utilizing the power of the 'Rumble-Rumble Fruit', they generate minute lightning while radiating electromagnetic waves of a unique frequency, obtaining information by sensing the reflection and feedback of these electromagnetic waves. Then, they use 'Observation Haki' to interpret the information, thereby gaining a search range far exceeding that of ordinary Observation Haki.

Using this method, Roman can greatly extend his detection range, and can continuously search an area of hundreds of nautical miles without any problem, which is dozens of times larger than the detection range of a top expert's Observation Haki!

Of course, unlike Observation Haki, which can specifically distinguish the number, strength, and emotional fluctuations of targets, Roman's 'scientific' search method can only obtain a rough 'shape,' unless a large number of white doves are scanned repeatedly to obtain a clear image. However:

It's incredibly effective at searching for ships on the vast ocean!

Why are there pirates everywhere in this world?

One reason is the corruption of the World Government, the uneven quality of royal families in each country, and the constant warfare, which has led to widespread suffering and the rise of numerous warlords.

On the other hand, it's also because this world lacks effective reconnaissance methods. Navigation still relies on compasses and the naked eye of lookouts, which means that even though the navy has far superior strength to pirates, most of the time they are just playing 'hide-and-seek' with them at sea.

The ocean is so vast, and the weather on the Grand Line is so unpredictable, that Marine warship and pirate ships often pass each other without noticing, resulting in the navy's low search efficiency. Roman's human lightning, however, doesn't have these problems—unless it encounters strong electric currents.

"If I had joined the Navy from the beginning, I'm afraid Luffy wouldn't even have had the chance to enter the Grand Line."

Lying on the deck, Roman chuckled self-deprecatingly. He thought that even a small leak of a world's technological foundation could drastically alter its course. Of course, Roman had no interest in ending the Great Pirate Era ...

"Colonel Roman, what did you just say?"

Roman calmly waved his hand at Major Isca, a beautiful young woman who had just finished showering after exercising and was radiating youthful energy.

"It's nothing, just reminiscing. But that's not important: there are two pirate ships forty nautical miles away at three o'clock!" With that, Roman flipped his hand, and several portraits appeared in his palm.

"Take a look at what kind of trash this is."

After a large-scale search revealed the ships, a large number of white pigeons observed them up close, sketching those whose "style" clearly distinguished them from ordinary soldiers, and then passing them over to Isca for identification.

"The 'Horn' Danton with a bounty of 60 million, the 'Blood Axe' Richie with 44 million, the 'One-Hand' Mara with 32 million... a bunch of thugs who burn, kill, and plunder!"

What kind of deformed fruits are they?

"Move the boat closer,"

"Major Isca, Captain Borgin, the battle is yours."

"Yes!" x2

As the warship accelerated towards the three o'clock position, two pirate ships came into view a few hours later. Regarding this:

"Prepare for boarding action!"

With his blond hair tied back in a ponytail, Polkin, now a dashing and carefree man, brandished his Borgin and began directing the battle. As for how Colonel Roman categorized pirates? What does that have to do with me? The important thing is to avoid getting 'wounded' in the fight later.

"A mere warship with only officers at the colonel level dares to come looking for trouble?"

Standing at the bow of the ship, Captain "Horn" Danton of the "Crushing Pirates," wielding a giant trumpet-shaped weapon, curled his lip in disdain. Especially when they saw the enemy charging straight in for boarding action without firing a single shot, the pirates burst into laughter!

"Hahaha, is the enemy commander some parachuted-in idiot second-generation rich kid?"

"They're ignoring their firepower advantage and instead engaging in close-quarters combat with pirates?"

"Hahaha, let's teach these sailors a lesson!"

"Excellent, it seems we'll soon have a third ship..."

'Trunk' Danton stroked his messy beard;

"Great, it seems we'll soon have our thirteenth ship."

Roman, sitting on the sun lounger, stroked his smooth chin.

With the tacit understanding between the two leaders, the three ships rapidly approached each other on the sea without firing a single shot, and then:

"Kill them!"

"Kill those navy sailors—"

"Hahaha, there's a woman here? She's mine, nobody can take her from me!!"

Several of the pirates' "experts" leaped into the air with a push of their feet, while the less skilled ones swung across using the ropes; the even more skilled ones threw out grappling hooks to connect with the ship, then charged forward on the ropes...

What, lay down wooden planks?

Even if you're just a grunt on the Grand Line, you should at least be able to perform rope-walking charges and lift a cauldron, otherwise you might as well go back to the Four Seas and go fishing.

"Maintain formation,"

Despite the swarm of pirates, Borgin remained calm.

"Don't steal kills, focus on teamwork and cover for each other..."

"Whoever is most injured goes to flush the toilet."

???

'Blood Axe' Richie, who leaped through the air, was enraged! A mere naval lieutenant, with a low rank but a big mouth!

"Court death!"

He raised his signature weapon, a massive axe weighing several hundred kilograms, Guotou with both hands, and leaped forward with a thunderous roar, the axe in his hands accompanied by a gust of evil wind, directly cleaving towards the blond lieutenant.

This axe blow would leave even Sea King with a bloody head, let alone a human!

Clang!

Then, with a piercing crash, the giant axe abruptly stopped from its rapid movement! The massive axe was blocked in mid-air by the opponent's 'slender' saber, accompanied by Borgin's disgruntled voice.

"Hey big guy, don't damage our warship's deck!"

Beneath Borgin's feet was a 'sunken' deck. The reason it didn't explode was, of course, because Roman had laid down a layer of paper beforehand.

Wood and steel are both too fragile for the experts in this world.

"Don't get cocky! We outnumber you several times over, brothers, charge!"

Powerful, heavy slashes, gleaming swords, and a hail of bullets and cannon fire! The entire warship deck was instantly transformed into a hellish scene of blood and fire! But as the fighting continued...

"Damn it! Why are all the ones who have fallen our people?!"

Just as 'Trunk' Danton opened his eyes wide in disbelief, a flash of light slashed across his waist.

"You brat!"

The pirate captain, enraged by the long wound Isca had inflicted on his waist, was furious.

I'm going to fuck you to death!

The enormous megaphone in her hand swept towards him with a terrifying whooshing sound, but Isca easily dodged it with Geppo, and the two quickly became locked in combat! Only then did 'Megaphone' Danton realize that this young female officer's strength was actually on par with his own—this was troublesome...

After the battle had lasted for about half an hour, 'Horn' Danton's impressions had become:

This is it!

As the pirates on his two ships were defeated one after another, Danton, covered in blood, was also caught off guard by Isca, who cut off his weapon with a single sword strike and knocked him down in a pool of blood amidst a dizzying spin.

I should have known better than to covet that warship!

Danton, nicknamed "The Trumpet," possesses superhuman lung capacity, which, combined with his weapon, allows him to unleash wide-range sonic attacks capable of shattering ships and human bodies! If he had unleashed his ultimate attack right from the start, he would never have ended up in this predicament:

Our side is completely wiped out, yet the navy hasn't suffered a single death?!

This is not scientific.

Thump!

The pirate captain, who had been kicked in the back of the head, collapsed on the deck and his vision went black.

After the battle:

"Anyone with fewer than three injuries, step forward!"

No one in the entire team moved.

"If you have more than three 'moderate injuries,' step forward!"

Dozens of sailors, covered in blood, stepped forward.

"An extra hour of training!"

"Yes!"

"Anyone with more than three 'serious injuries', step forward!"

Three bloodied and mangled figures took a step forward.

"Go clean the toilets!"

"Yes!"

"Boss," Borgin Guotou to look at Roman.

"Including these two, we've captured thirteen pirate ships. If we were to take them all..."

There is clearly not enough manpower.

"Um,"

Roman stood up and nodded.

"It's time to return to port—back to Marine Headquarters!"
