As artillery became more powerful, the traditional walls became useless.

Therefore, the Jucinot Line of the Ming Dynasty was not a traditional fortification like the Great Wall, but a modern military defense belt.

As the name suggests, Giulcino does have many similarities with the famous Maginot Line in World War II, or it can be said that he stole from the French chicken.

Anyway, if there are more lice, it will not itch, and if there are more debts, there will be no worries.

Zhu Fugui, who has already studied under Great India, Chang Kaishen, and Yuan Datou, simply gave up on himself and learned advanced experience from Faji.

Although the daily milk method was one of the few pastimes in the life of Zhu Fugui's lonely emperor, the Maginot Line itself was absolutely qualified as a barrier against the enemy.

In 1928, France built a defensive line about 390 kilometers long along the border to defend against a German invasion.

This line of defense, which costs half of the French defense budget, about 4 billion francs, is known as a line that will never be breached.

And that's exactly what happened.

Due to the Belgian pit chicken behavior, coupled with the surprise of the Germans to break through the Ardennes Forest with 2.5 million elite main forces, the Nac army peaked in Paris.

In the end, Maginot was not in time to prove his worth before the white flag was flown in Paris.

But the fact that Hittler was forced to take the risk of using troops in the Ardennes Forest, where the terrain was rugged and densely forested, and which tanks could not travel, has also proved the value of Maginot.

Therefore, the humiliation of the French chicken is not the fault of Maginot.

Without Maginot and using these 4 billion to raise troops, it would be easier for the Germans to attack, after all, it is a question of who can better withstand the steel torrent of the Germans or the stumps of the Ardennes Forest.

Maginot was eventually caught off guard due to its long defensive lines, and for the Ming Dynasty, the terrain of the Xinjin Peninsula surrounded by the sea on three sides was far easier to defend than in mainland France.

The cavalry of the Western Army of the United States had to take the narrow 3-kilometer peninsula-mainland connection to attack Xinjin.

As long as the Ming Dynasty can hold these three kilometers, Xinjin will be impregnable, because there is no navy in western North America that can fire at the Daming shore artillery and complete the landing operation.

As for whether the enemy will bypass Zhu Chino and directly attack Fengdu, that is exactly what the Ming Dynasty could not ask for, and the Ming Dynasty's mechanized corps could just take the initiative to attack and annihilate the enemy in sections.

The Jianzhou Jurchens bypassed the city of Beijing, went directly to the Shandong Peninsula to burn and loot, and then swaggered and calmly withdrew from the Guanwai, and the absurd things of the city garrisons along the way were all watched on the wall, and it was impossible to repeat it in the Fourth Ming Empire.

In the Maginot Line, there were 5,800 permanent fortifications of various purposes, with a density of up to 15 per kilometer of frontage.

Although the Ming Dynasty was not as wealthy as France, its own defensive line was also short, and its strategic depth was not as exaggerated as Maginot reaching 20 kilometers.

The length of the Jucinot defense line of the Ming Dynasty is 3 kilometers, and the strategic depth is 5 kilometers.

The density of permanent fortifications, or pre-formed semi-permanent fortifications, also reached the same 15 per kilometer of frontage.

That's right, the actual Juchino is not so much a wall as a long and narrow plug that is stuck on the Xinjin Peninsula.

The so-called permanent fortifications refer to the relatively strong fortifications that can be used for a long time and are built in advance with strong and durable building materials.

Its strength is definitely not comparable to that of temporary fortifications built with sandbags, rammed earth, and sapper shovels.

For Zhu Fugui, many prefabricated parts that could be imported from later generations were no less powerful than permanent fortifications, which were not something that the French could imagine in the twenties and thirties of the twentieth century.

The original intention of these prefabricated parts is to be used for disaster emergencies such as flood fighting and rescue, as well as the construction of so-called 3D printed buildings, so the cultural value penalty is not very high.

Of course, Zhu Fugui bought to learn from friends in the Middle East to reprocess and extend the development of these products, which is not something that the system can govern with a long arm.

Zhu Fugui has almost realized that this dog system is about the same as all kinds of nosy international organizations, as long as he learns more from his friends in the Middle East, he can always find a way to bypass supervision and obtain military supplies.

Whether it is a gas tank or a crude oil cylinder, or a fire extinguishing drone and a wasp drone, there is always one suitable for Daming.

The most common permanent fortifications in Giuchinot are bunkers.

The exposed part of this French-style bunker is only about a little more than a meter high, and the warriors need to bend down to enter.

In addition to observing the shooting holes, the above-ground structure is basically a cement mound, with a thickness of up to 0.7 meters on the roof and walls, and in some places even welded with iron plates 4 centimeters thick, which can withstand several or even dozens of bombardments from the most powerful artillery of this era.

Moreover, the bunker is also connected to other bunkers through underground passages, and once the above-ground defenses are blown away, the warriors can retreat through the tunnels.

On the contrary, if the enemy wants to break into another bunker through the tunnel or release poison gas, they will be blocked by elaborate partitions.

In addition to the tunnels, the interior of the bunker also has a complex internal structure, including storage rooms, rest areas, wells, etc.

Compared with the original design of the French chicken, the engineers of the Daming Ministry of Engineering took into account their own conditions and the weak expectations of the enemy's firepower, and simplified the bunker, but the core area was still dug out.

That is, each of these bunkers, capable of fighting independently, became a nightmare for enemy troops.

Although the bunker was only a relatively low-level simple fortification in the Maginot Line, in the Jucinot Line, the bunker was an intermediate force.

For the enemies of this era, this is almost an insurmountable barrier.

This is also one of the reasons why Zhu Fugui chose to cast fortifications instead of blindly expanding the army.

The current civil engineering capabilities of the Ming Dynasty are far ahead of the times, but the weapons and equipment, especially the firepower equipment, do not have any advantages.

In addition to the bunker, there is 1 defensive command post, 2 backup command posts, several ammunition depots, ambulance stations, power stations, filtration and ventilation rooms.

It may seem complicated to say, but in fact, it is just a matter of digging out large and small potholes and tunnels, and then pouring the above-ground parts with cement and prefabricated parts.

This kind of civil engineering work is an old practice for Chinese workers.

Zhu Fugui didn't know why Maginot had to dig for 20 years and spend so much money, directly, Zhu Fugui felt that handing over the Maginot to the Germans to dig could shorten the construction period by 1/3, and letting Chinese workers dig could shorten the construction period by at least half.

In addition to these underground fortifications, another component of the Jucinot Line was a dense network of trenches and barbed wire on the ground.

The barbed wire was bought by Zhu Fugui from the platform, and is the same as the barbed wire fence used by the Qiantang River dam to prevent tourists from climbing (see the comment section of this paragraph for a schematic diagram).

The trade name is [galvanized blade barbed wire barbed wire rolling cage wall], and the price is 50 yuan per ten meters.

Zhu Fugui directly pulled more than 20 kilometers, and pulled it around Fengdu and Fugui Palace.

After the merchant discounted, it cost a total of 100,000 yuan, and because of the simple structure, the cultural value consumption is not much, which is really cheap and affordable.

Such a high-density barbed wire, with blades on the barbed wire, is definitely not something that the Yankees can wear through in the flesh.

Of course, the merchant also wanted to sell the electrification device to Boss Zhu, saying that bringing high-voltage electricity was the complete body of this barbed wire.

Although Zhu Fugui was very greedy, considering that the damage had completely overflowed, he did not spend this unjust money.

Besides, those ghosts are scorched on the barbed wire, and it's a hassle to clean up, isn't it?

In the day and night rush of the Ming army and civilians, on March 3, 1864, the Jucinot Line was officially completed.

At this time, Zhu Fugui was finally able to put his feet on the sky, set up Erlang's legs in the Fugui Palace, and waited for the foreigners to knock on the door.

This mentality is probably equivalent to playing League of Legends, and the wild dragon turtle finally came up with a fanatic, anti-armor, ice heart, and sun flame, and waited for the ADC (except VN) for a while.

This cat's claw-like mood makes people quite impatient.

However, it is depressing that until late March and early April, the land has begun to bloom, and there is still no movement in Seattle.

This made Zhu Fugui unable to sit still, and announced that Qi Wenchang, the envoy of Jinyi Weibei Town, was calmed down.

Beizhen Fusi is in charge of espionage, internal security, guards, coast guards, border guards and other troops, and spying on intelligence is naturally also a matter of responsibility.

After understanding the holy will, Qi Wenchang suggested sending spies to Seattle Town to find out the truth.

When Xinjin was broken through last year, a few ** rescued from the basement of the Yang Monk Temple were barely usable after nearly half a year of brainwashing and training.

In particular, two of the children, who were badly devastated by the priests, have become staunch haters of the Church under the cultivation of Jinyiwei, determined to destroy the Church and slaughter the Pope.

Although in fact, it was the Protestant leaders who persecuted them, and it really didn't matter what the Pope did...... But that's how Jinyiwei instilled it.

Zhu Fugui agreed to this plan.

These white imps have eaten half a year's white rice, and it's time to make some contributions to Daming. Anyway, they didn't know much about the core intelligence of Da Ming, and Zhu Fugui didn't have to worry about their defection.

On the contrary, their white faces and their proficiency in English make it much easier to inquire about information than ordinary spies.
