The fall of Wano country really shocked everyone.

Except, of course, in the upper echelons of the Navy.

After all, others don't know about Kaido's situation, but those in the navy do.

But in any case, the revolutionary army has always come to the front and occupied one of the most important areas in the world.

Wano country, the only place with sea floor stone processing technology.

Of course, this refers to the original work. Now, in addition to Hezhi, Li Yan also has the ability to process sea floor stones.

To put it bluntly, the reason why Hailou stone is difficult to process is because of the hardness.

Take Doflamingo's artificial fruit factory in the original book as an example, its outer wall is built with sea floor stone, and it can even resist the cutting of bird cages.

Obviously, these are not a problem for Li Yan, after all, there are various tools across the ages, but for the Holy Land Mary Joa, it is a headache.

Although the country of Wano used to be controlled by Kaido, and it was also hostile to the Holy Land, but the hostility turned into hostility, and everyone still had to do business.

Therefore, the Holy Land can also purchase and process Hailou stone through Wano Kingdom.

But now?

Now that the country of Wano is occupied by the revolutionary army, will Drago negotiate business with you in the Holy Land?

Think too much?

If Vega Punk was still there, this processing problem might be solved, but unfortunately, Vega Punk has now gone to Li Yan's side.

Therefore, apart from Hezhi, in the entire world today, only Li Yan has the ability to process Hailou stone.

If this is replaced by other places, I am afraid that the Holy Land will have assembled troops to kill it, after all, this is completely stuck in the neck of the Holy Land.

But it is the country of Wano, a place that is easy to defend and difficult to attack.

Unless it is like the revolutionary army, sneak in, and then control the diving port.

As for climbing the waterfall, Drago had already had a gun there, and it smashed you halfway through the climb.

It is definitely not an easy task to conquer Wano Kingdom.

For Li Yan, the only pity this time was that Kaido ran away for some unknown reason.

Originally, according to Li Yan's idea, it was planned to let Vega Punk study Kaido's body, explore the reason why he could bear two Devil Fruits, and see if he could create a pacifist version of Kaido.

But now it seems that it will not work in the short term.

But, well...

In fact, even if he didn't study it, Li Yan could roughly guess something, either his physique was strong enough to break through the limit, or his body was abnormal.

And Kaido mostly belongs to the former. After all, looking at the speed of his wound recovery, it is obviously abnormal.

Wait, restore speed...

Could it be that the speed of recovery has suppressed the speed of damage to the body by the double fruit?

If that's the case, what about his unique feature called high-speed recovery?

"System, after the high-speed recovery level is increased, is it possible for me to eat the second fruit?"

[Ding, yes, if you reach full level, yes]

Well, that's true, but the problem is that even if you want to reach the full level, you can't do it in a short time.

It can only be said that there is hope, but this hope is very far away.

Forget it for now.

East China Sea, Corona Island.

Carrera East China Sea Branch.

"12,000-ton class, or the main warship?"

After listening to Li Yan's explanation, Barry was a little confused.

During this period of time, ironclad ships have been built larger and larger, in order to accommodate more powerful firepower.

After all, those large-caliber naval guns are all heavy, and small warships simply can't handle it.

Even the two battleships launched some time ago have reached the level of 50,000 tons.

Obviously, large tonnage is the current development trend, but Li Yan said...

The main surface hull of the next-generation navy needs to compress the displacement to less than 12,000 tons?

This size can't hold those large-caliber artillery, I am afraid that at most a set of two 280mm can be installed.

"Yes, it's enough to keep one gun, and the caliber doesn't need to be too large. In addition, you only need to be responsible for the hull and the assembly of the subsequent equipment after arrival."

"For power, go to Levine. He is testing a gas turbine recently and should be able to help you a lot."

A few minutes later, when Barry ran to find Levin, Li Yan looked at Franky.

"Help me design an aircraft carrier."

"Aircraft carrier, what?"

On the side, after listening to Li Yan's words, Frankie was also a little confused.

He really didn't know what an aircraft carrier was.

"Well, you can understand it as a kind of warship that allows planes to take off and land on it."

"Uh, what is an airplane?"

"It's the kind of weapon of the revolutionary army."

Li Yan said casually.

Speaking of which, maybe the cooperation between Li Yan and Drago is definitely a secret, but in fact, many people in Carrera know it.

after all...

Those warships of the Revolutionary Army are all made by them, okay?

Therefore, they often see photos or videos of revolutionary warships on the news. If they can't recognize it, it's a hell.

However, with a systematic confidentiality mechanism, Li Yan is not afraid of them leaking secrets.

I didn't see any boatmen involved in the manufacture of the revolutionary warship, even Kaku, but he had no way to leak the news.

But knowing that he knows, but Franky is still a little confused about what an aircraft carrier is.

After all, he had never seen how a fighter plane took off and landed.

Li Yan, who had already prepared for this, took out a sketch.

Anyway, I also have a talent for designing SS-class ships. In addition, although I was not very proficient in my previous life, I still knew the general appearance of an aircraft carrier, so it was very easy to draw a simple design.

"Is this the aircraft carrier you're talking about?"

"Well, the full name should be an aircraft carrier, a large surface ship with carrier-based fighters as its main combat weapon~lightnovelpub.net~ can provide take-off and landing of carrier-based fighters."

"But isn't this design without self-protection? Once the enemy approaches..."

Looking at the aircraft carrier on the blueprint, except for some close-up weapons, there are no heavy weapons such as naval guns, Frank asked in a puzzled way.

"Are you stupid, now the combat radius of fighter jets can reach more than 1,000 kilometers. Is it possible to get close...?"

"Moreover, the aircraft carrier is not used alone, but as the core of the fleet. If the aircraft carrier is to be destroyed, unless the entire fleet is defeated."

It turned out to be so.

Franky understood a little, and then nodded.

"Leave it to me, it will be fixed for you in at most two months. By the way, how big is it?"

"If you build it for the first time, you can carry 48 fighters. I will send you the size of the fighters to be boarded later, so that you can design the interior space."

After thinking about it, Li Yan said.

After all, this is the first attempt to build an aircraft carrier, so don't take it too far.

After the first one has experience, consider a larger, more professional and more versatile aircraft carrier.

Now what...

A simple maritime mobile airport will do.
