During the era of battleships and big guns, one major problem was accuracy.
Especially during long-range bombardments, hitting even 2–3% of the time was considered good. If the weather was poor, even achieving 1% accuracy was difficult.
This issue also exists in the world of pirates.
At this moment, the problem Seras was solving was exactly that—accuracy.
"Captain, this is a support device for Observation Haki radar. Its purpose is to assist the radar by enabling it to lock onto a specific target and accurately determine its range and position."
"Based on our estimates, when used in conjunction with a ballistic calibration system, the accuracy of a warship's main cannon at a distance of ten kilometers could be increased to around 38%. Even at distances over twenty kilometers, it could still maintain an accuracy above 10%."
"Of course, this assumes the user's Observation Haki range is sufficient to cover that distance."
Accuracy of 38% at ten kilometers?
And even at over twenty kilometers, it still maintains over 10%?
Damn. That's over a tenfold increase in hit rate for the main cannons.
This thing really is incredible!
But...
Observation Haki radar was great, sure—but currently, very few people in the branch could actually use it.
And those who could wield it to its full potential? For now, only Luo Lan had that capability.
Even Hina, despite a thirtyfold amplification device, still fell short.
"Captain, actually, we've developed two versions of this ballistic calibration system."
"One is the active version, which is fully functional and works just as I described. The other is the passive version…"
"Unlike the active one, the passive version doesn't require an Observation Haki user to operate. Instead, it passively receives data from another ship that has an active version. One active system can support up to eight passive systems at once."
It was like Seras could read Luo Lan's mind—he continued speaking right away.
And Luo Lan was stunned.
Damn, Seras basically created a data link system?
With this, there'd be no need to station an Observation Haki expert on every ship.
In fact, an entire fleet would only need one Haki user on the flagship.
Fantastic. Absolutely fantastic!
"Seras, what's the third item?"
Luo Lan was already thoroughly impressed with the first two.
Now only the final piece remained.
"Captain, this third piece of tech actually wasn't in Director Roy's original blueprint."
"Huh? Why's that?" Luo Lan frowned.
If it was good tech, why wasn't it included?
"Well, you see… the science division had previously considered designing a completely new main cannon to replace the current cannons. They even made some promising breakthroughs, but..."
"Although we had partial success, the technology is still very immature and cannot be installed on a ship yet."
As he spoke, Seras unrolled a design diagram.
Instead of a traditional gun barrel, two rail-like structures extended from a massive turret base.
The moment Luo Lan saw it, it felt strangely familiar.
The second glance confirmed it.
Wait a minute...
Could it be… the thing he had thought of?
"Seras, explain it."
"Yes, Captain!"
Seras nodded and began his explanation.
"Captain, as you know, we've made great strides in using cola-based energy. While working on that, we also explored other more efficient energy sources. And then we discovered…"
"The power of lightning!"
"This idea came from one of our A-rank scientists. Since everyone knows lightning contains terrifying energy, the question was—could we harness it?"
"To pursue this, we created a special research project to study how to convert unstable lightning energy into stable electricity, making it usable and controllable."
"Surprisingly, the project progressed rapidly. We even developed a device that converts cola energy into electricity. Using that, we designed a prototype main cannon—what you see in the blueprint."
"Unlike our current artillery, this conceptual cannon fires solid metal projectiles powered by immense kinetic energy."
"According to current theory, its single-point destructive force could rival the full-strength attack of a top-tier martial arts expert, with a range reaching hundreds of kilometers."
Hiss—
Everyone in the room sucked in a breath.
This was… wild.
Top-tier martial artists? That meant people like Garp!
A full-force attack?
Even if it was just comparable in terms of concentrated damage, that alone was already insane.
And the most outrageous part—its range was hundreds of kilometers, and this was only the first generation?
If future versions improved… would they be able to fire from Rhodes Island straight at Mariejois?
Completely ridiculous!!
Luo Lan was even more stunned.
He had suspected it just from the design diagram.
And now it was confirmed—it was the thing he imagined!
"Seras, forget just generating electricity—you actually made a railgun?"
"Captain, a railgun? Is that what you're naming this prototype cannon?"
"Uh… yeah, exactly. From now on, we'll call it the railgun!"
"Got it. That name fits it perfectly."
Seras agreed without hesitation.
"Seras, you mentioned it can't be installed on ships yet. Why?"
"Because it's too big!"
"But the blueprint's specs don't seem that huge?"
"Captain, what you're looking at is just the cannon itself. To actually operate it, we need the energy conversion device that turns cola into electricity. That machine is nearly half the size of a second-generation warship. Worse still, our current energy conversion efficiency is only about 10%. The other 90% is lost during conversion."
Alright, Luo Lan understood now.
There was no way this thing could be ship-mounted yet.
Not only was the converter enormous, but it also wasted too much energy.
But wait…
If that's the case, why was Seras talking about this in the first place?
At that moment, Seras smiled faintly.
"Everyone, while it was previously unusable… a perfect solution has just emerged!"
"What solu—wait a second. Seras, don't tell me you're thinking of Ace?"
Halfway through his question, Luo Lan suddenly realized.
Electricity…
Of course! There was no need for a bulky energy converter.
Just have Ace power it directly!
"Exactly. That's what you were thinking too, Captain!"
"Though this also means… not every ship can be equipped with it."
"After all, we only have one Ace."
Seras nodded.
Luo Lan turned to Roy.
"Roy, do you think we can install this thing on at least one ship?"
"No problem. Based on the blueprint's size, if we remove both main forward cannons from the ship's bow, we'll have just enough room."
Roy responded immediately and decisively.
"Good. Then it's settled. The flagship will retain only the rear main cannon. As for the front…"
"Give me the railgun!"
