For the big guys who have developed to the golden rank, the relevant knowledge is already available in their own civilization.

What's more, even if he comes to rescue, he doesn't owe much in favor.

It would be great if he could just use some props or civilization points to purchase/exchange them.

In this way, after a short period of thinking, Xia Qi quickly made a decision.

As for the candidate, he went straight to Xiongba.

However, after he sent the message, he did not get an immediate reply from the other party. He must be busy with something.

At this time, Luo Xiaohei ran in from outside the hall.

"Your Majesty, Hal wants to see you."

Hal was the elf druid when Xia Fox tested the biplane fighter earlier.

To avoid disturbing Zhang Liang and the others' work, Xia Qi also moved to a side hall.

Looking at Hal in front of him, he asked aloud: "How is the test going on the biplane fighter?"

"Reporting to Your Majesty, the bi-wing fighter has been successfully developed."

Then, Hal quickly reported on the test situation.

In terms of flight altitude, the flight altitude of more than three thousand meters is extremely low compared to the goblin airship.

However, one of the most important reasons why airships are eliminated by airplanes is that they fly slowly and are not flexible enough.

In the air, it lacks the ability to deal with and fight with other air units.

Although it far exceeds that of airplanes in terms of flight altitude and bomb carrying capacity, it also has reconnaissance capabilities that far exceed those of airplanes.

However, the emergence of aircraft threatens the living space of airships in the most direct way. Once these two air units face each other head-on, the airships cannot defeat the fighter jets at all.

However, Xia Qi is not worried that those goblin airships will have nowhere to arrange them after they retreat.

The carrying capacity of airships is still considerable, and most importantly, the cost is cheaper than airplanes.

After retreating from the front line, it would not be a loss at all to directly modify it and use it as a transport airship.

As for the question of how many of this first biplane fighter should be produced, after looking at the production costs, Xia Qi didn't have any psychological pressure.

Compared with the black-tech tanks and chariots of the dwarves, the cost of this bi-wing fighter was too cheap for Xia Qi.

The cost of one unit is 1.35 million.

Originally, according to the previous configuration, a biplane fighter would not cost so much, but the problem was that Xia Hu equipped it with a geocentric engine.

Things from the dwarves are never cheap.

But fortunately, the performance has also been improved, which is not a loss at all.

However, although the cost of building this bi-wing fighter is relatively cheap, Xia Qi does not plan to build too many.

For Xia Qi, the biplane fighter is just a springboard. If it is overused, he will next develop the first generation jet fighter. When the first generation jet fighter is successfully developed, the biplane fighter will be eliminated.

Therefore, there is no point in building too many.

"Then... let's build three hundred of them first."

Xia Qi set a number for himself in his mind: no more than a thousand bi-wing fighters.

With a thousand biplane fighters, coupled with the special civilized air force, even against some gold-level players, it should be able to perform for a while.

In this way, after confirming the production plan of the biplane fighter, Xia Qi took out the gold-level first-generation jet fighter design drawing and motioned Hal to make another trip and hand over the design drawing.

To Xia Fox, the director of the Ordnance Research Department.

By the way, I would like to convey a message to him: while building fighter jets, don’t forget to study bombers as well.

There are two types of aircraft, each with its own uses.

Fighters are used to fight for air supremacy, while bombers are used to bomb enemy ground units or sea units and deal damage.

If there are only fighter jets but no bombers, then the next battle will be a bit difficult.

After giving instructions on another matter, Xia Qi took out his small notebook with a development route drawn, then took a pen and crossed out the line "Develop bi-wing fighter jets", and then added "large-scale construction of military airports" and "

Put a check mark behind these two items: "Develop the first generation jet fighter".

At the same time, the next project is to develop the first-generation aircraft carrier!

Now, he has ordered the research and development project of the first generation jet fighter, and the biplane fighter is ready to be put into production, so it is time to start the research and development of this aircraft carrier.

It is impossible to really wait until the first-generation jet fighter is successfully developed before starting to develop the first-generation aircraft carrier. The efficiency would be too low.

After half a month of court meeting, Xia Qi formally proposed this huge and expensive project.

After hearing this, the old minister of the Ministry of Finance almost jumped out to object.

Fortunately, he also knew that this aircraft carrier was an indispensable part of the development of civilization.

Of course, understanding is understanding, but the look in Xia Qi's eyes was full of resentment.

Xia Qichun didn't see this, and immediately officially launched the "first-generation aircraft carrier" research and development project at the North Korean meeting.

In this limited development time, Xia Qike has a lot of projects to work on.

Especially in recent times, the mass production of dwarf tanks and biplane fighters, coupled with the formal establishment of project teams for the first-generation jet fighters and the first-generation aircraft carriers, and a series of major actions such as investment in research and development, have directly led to the

Daxia's economy, which had just become affluent, suddenly became tense again.

It seems that in the next few years, Xia Qi will have to be more stable, otherwise, Daxia's financial pressure will be too great.

Change source app, and view the latest chapters of this book on multiple sites at the same time.】

Of course, even if there is no additional project, he can still take care of other things.

For example, send out several reconnaissance troops to open up the surrounding field of vision.

The discovery of indigenous cities on the western grasslands in his early years also made Xia Qi realize that he had been a bit slack in broadening his horizons in recent years.

The main reason is that the environment in those places is too harsh, and he has no plans to expand his territory into the desert or frozen soil in the short term, let alone build a city, so the exploration has been put on hold.

It wasn't until the appearance of the western grassland natives that it gave him a wake-up call, and he began to send out reconnaissance teams again.

And just as he was opening his sights on the main continent in an orderly manner, the Nuclear Energy Research Institute built in the bitter cold land also sent a formal report.

On this day, Daxia's first nuclear reactor was successfully developed!

This is a very important step for a civilization.

This does not mean that mushroom bombs can be made, but that from this day on, this civilization has officially taken the first step towards the atomic energy age!

Atomic energy is a good thing. The energy it contains is many times stronger than ordinary energy.

In the real world, top aircraft carriers or submarines are all nuclear-powered.

Later, if conditions permit, nuclear power plants can be built.

The consumption is much less than that of thermal power stations.

As for the mushroom bomb, as a strategic-level weapon, of course it must be developed.

However, it's hard to say how useful it is.

At least for Xia Qi at this stage, even if a mushroom bomb is developed, the deterrence of that thing is definitely greater than its practicality.

There are always people who think that with mushroom eggs, they can do whatever they want.

Actually, that's not the case at all.

In fact, the early mushroom eggs were, to put it bluntly, just paper tigers. It was extremely laborious to use them.

Take the real world that Xia Qi was in before as an example. The first country to create and use mushroom eggs was Beautiful Country, and for a period of time after that, other countries did not have any atomic bombs.

According to what I just said, if mushroom eggs were truly invincible, the Lighthouse Country would have neutralized the world long ago.

But the fact is, no.

As for the reason, naturally it is not that some beautiful country is a gentleman, but because, in that matter, it is really very difficult to use mushroom eggs.

Unless it explodes on the spot.

The fundamental reason why this situation occurred was that the power supply battery for the detonation system in the mushroom bomb was not durable enough at that time and could only last for about thirty hours.

At the same time, due to the heat release problem of the plutonium element in the mushroom bomb and the corrosion problem of the battery, after a mushroom bomb is assembled, it basically has to be disassembled and charged to replace parts every once in a while, or it can be completely dismantled and turned into

Component.

Therefore, at that time, there was basically no "hoarding" of mushroom bombs, and they would only be assembled when needed.

After assembly, bomb delivery is also a problem.

Under the circumstances at that time, the only means of dropping bombs was to transport them by airplane and conduct airdrops.

Here, distance becomes a problem.

Taking off from the airport on your own territory and flying to someone else's territory to drop mushroom bombs is not as easy as it sounds.

At that time, the flight time and flight distance of aircraft were very limited, and the mushroom bomb itself had time limitations due to the above reasons, and enemies that were slightly farther away were not within the strike range.

And if we assume that the enemy is just within the attack range, then, according to the technology at the time, there is basically no accuracy in airdrops.
