Although the sea route is a strategic resource transportation route and is very important, Chris can only let his navy sail in the wind-powered sailing battle. It's not that his skills aren't up to the level of building steel battleships, it's that he really doesn't have that many resources to work with.

Steel has now gone from being a not a scarce resource to a strategic scarce resource that needs to be tightly controlled. Not to mention the construction of countless steel warships for the navy, even equipping the navy with those 60 cannons is a difficult task.

At the beginning, Desel, who was in the city of Seris, even planned to equip each battleship with 2 cannons to cope with the errand, but Chris vetoed it, so he gritted his teeth and opened a production line specializing in the production of naval artillery.

The same is true for the power system, although the steam engine has been miniaturized and can be installed in a train, it is still in a state where demand exceeds supply. Not only did the train need more locomotives, but the factory also needed more steam engines to expand its capacity.

With the gradual increase in electricity consumption, more thermal power plants have also begun to be put into use, and more steam engines are occupied by thermal power plants, so it is not at all the turn of naval warships to compete for "units that have nothing to do with production and transportation".

Don't you see, for a few steam engines, the railway department, the power department and the factory are about to break their heads, and countless high-level executives of Iran Hill have almost rolled up their sleeves and fought together, and the ones who scolded the street are all bigwigs like Gullodiens, and how old are the few staff officers in the navy who have no names and no surnames?

The steel hull could not be made because of the lack of iron, and the power system could not get the machine because it was not ranked, so the Navy's steel warship project was shelved indefinitely, and it was still possible to use traditional shipbuilding technology and make sailboats from wood.

After all, although everyone knows that the navy is also very important, now that the navy is obviously not in the main operational direction, the decision-making level, including Chris, can only forget about the expansion plan of the navy and devote all their minds to defending the Holy Demon Empire.

Even so, the development of the Navy is actually very fast. What Chris brought is the optimal design of sailing ships that has evolved over the centuries of civilization on earth - the strength of Europe was originally built on sailboats, and those famous sailboats are naturally more advanced.

And how powerful these warships are after they are equipped with modern artillery needs to be tested in actual combat. Now Iran Hill has not yet had the heart to test the strength of the navy, they are frantically expanding their ground forces.

Actual combat is the best means to test the troops, and after the test of war, the top brass of Ellan Hill has realized that the second-line garrison regiment, which is simply armed with rifles, is vulnerable when facing the attack of the Holy Demon Empire's army alone.

Therefore, increasing the proportion of heavy weapons in the army has become the top priority of the reform of the army of Irlanhill. Chris ordered to upgrade all the original garrison regiments to the main regiment, which must be equipped with sufficient anti-aircraft firepower before it can be used for combat.

Under this order, all the arsenals throughout Iran Hill were producing at full capacity, and one after another 30 mm caliber high-level dual-purpose guns were pushed out of the production workshop.

As the most important node and industrial town in the whole of Elanhill, Seris's defense system has been completely separated from the original city defense. The air defense system of the entire industrial zone is a super fortification built on a completely new design.

Around the industrial area and castle of Irlanhill, dozens of defensive towers were erected. These towers are like small castles, with turrets underneath and anti-aircraft guns on platforms above.

Each tower is in the shape of a five-pointed star, and on each corner there is a 30 mm high and flat cannon, which guarantees that there will be 3 anti-aircraft guns in any direction to open fire.

At the same time, in the very center of this five-pointed star, there is also a rotating device for installing large-caliber anti-aircraft guns that have not yet been put into production, or a newly produced auxiliary weapon for night air defense: searchlights!

According to the regulations, the two adjacent anti-aircraft towers must have one of the installed searchlights, which are uniformly powered by two power plants, one for special power supply, and one for switching.

At the same time, around these towers, there were machine-gun pillboxes that could lift the roofs, armed with Maxim heavy machine guns. The machine guns were all mounted on a fixed shelf and could fire both at the air and at the ground.

It can be said responsibly that Seris's current defense system is already the most powerful defense of the mortal empire. If Ildo had attacked Seris instead of Maricha (now known as Fallen Dragon) but Seris, he would have been wiped out in the first round of dives.

Although, because of the production volume, many anti-aircraft towers are not installed with so many 30-mm anti-aircraft guns, this defense system has begun to take shape, and it can definitely be said to be very strong.

Because of the fear that Seris would be retaliated by the Holy Demon Empire, the anti-aircraft guns produced in the past ten days have been strengthened here. Including the anti-aircraft artillery unit of the teaching regiment arranged in the field, there are at least ten field anti-aircraft artillery carriages strengthened, and the firepower is much stronger than that of Falling Dragon City.

Together with the 1st Regiment, which is returning to the division, there are more than 60 anti-aircraft guns in the vicinity of Seris alone, which can be regarded as a very sincere air defense force. Chris believes that with this level of air defense, even if the other party dispatches 30 dragon knights, it may not be able to bargain.

"But if the Holy Demon Empire dispatches 50 or more dragon knights, such an air defense force will be a little weak." On the way back, Chris worriedly analyzed Walter, the head of the regiment.

Walter didn't care much about this situation, in his opinion, if he could defeat the Magic Empire twice, he could defeat them three or four times: "Your Majesty, it depends on the reaction of the Magic Empire." ”

"If they fight back immediately and throw in 50 dragon knights or more at once, then we are indeed under a lot of pressure." Walter rode on his horse and replied to Chris, "But for every day they are slow, our chances are one more point." ”

His confidence was not unfounded, because Seris was producing more anti-aircraft guns every day, and as production capacity increased, the production of anti-aircraft guns would only get faster and faster. If the Holy Demon Empire delays for a few more days, Elanhill will be sure to increase the number of existing anti-aircraft guns by dozens or even hundreds.

By that time, even if a part of it was taken away, Seris would have at least twenty or thirty more anti-aircraft guns, and this was not counting the increase in the number of machine guns. At that time, the power of this already very complete air defense system will increase exponentially, and the pressure on the dragon knight will be even greater.

If it can't be attacked for a long time, and if it drags on for a few more days, Seris will have more anti-aircraft artillery, and then it will enter a vicious circle, and the losses of the dragon knight troops will become bigger and bigger, and finally they will fall into complete passivity.

"Then let's see how far those damn guys from the Holy Demon Empire want to expand this war." Chris tugged at the reins of his horse and said thoughtfully.

At this moment, in the wilderness of the territory of Elanhill, a steel beast let out a long roar. The train, carrying two full truckloads of natural rubber, as well as sea salt and other industrial products from Ferry City, sped across the wilderness, causing the civilians on both sides of the tracks to stop their work and look at the scene with curiosity that they had never seen before.

A wagon sped forward under the traction of the front of the train, and black soot gushed out of the train's chimney, dispersed on the roof of the train, and finally disappeared into the air behind it. It's faster than a horse-drawn cart, it carries more things than a horse-drawn cart, and what's more terrifying is that it can work without sleep.

Because multiple locomotives were produced at the same time, this two-way railway built in advance could also transport multiple cars at the same time, which was dozens of times more efficient than the original carriage transportation.

With this line, parts from the Mayne factory and daily necessities from Ferry City can be transported to Serris City at a very low cost – collaboration between cities has become more frequent and production has become faster.

"It's called a train, and the workers who built that railroad said the other day, and they said that there would be a train passing over it, and the speed was scary." A farmer waved a hoe in his hand and showed off his knowledge to his fellow villagers.

In fact, he didn't know why the train was moving, or how much cargo was in the carriage dragged behind the thing. However, in terms of volume, this thing called a train is already a very shocking new thing.

Roaring all the way, it only takes half a day for this train to go from Mayne to Seris, after all, the locomotive that Chris directly made is not the design of the original locomotive head.

This kind of train is at least at the level of the pre-World War I, and it is already a very practical design. With the capacity provided by these trains, Ellen Hill's transportation capacity has surpassed that of all countries and has embarked on a shortcut to development.

"It's huge! The scream is so loud, you must be able to get a lot of luck. Hearing the farmers around him showing off, the ordinary farmer who worked nodded and exclaimed.

"That's not it, I heard that with this thing, it will only take us one day to go to Ferry City in the future!" The farmer who was the first to show off and continued to work with his head bowed said without raising his head.

"This year's harvest is much better than last year's...... I heard that food prices have risen again? "The farmers, who no longer cared about the train, talked about what they were more concerned about. Anyway, for them, no matter how fast and powerful the train is, it is not as exciting as the increase in food prices......
