Since the arrival of the Spanish Armada in the port of Dunkirk in the Spanish Netherlands, the situation in Northern Europe has become increasingly tense, Denmark and Sweden have sent tens of thousands of troops to the Netherlands, and the British Navy has also begun to cruise in the waters of Northern Europe, ready to support the Netherlands at any time, and the Netherlands is frantically assembling various warships to prepare for the Spanish attack, and a big war is about to start.

At first, the Spanish navy and army were indeed advancing in the direction of the Netherlands, but halfway through, before they had exchanged fire with any troops, they actually withdrew to the port of Dunkirk, such a strange move is really puzzling.

The port of Dunkirk is still a certain distance from the Strait of Dover, and as long as the Spanish Armada does not leave the port, there is still no threat to the ships coming and going in the Strait of Dover, so the great powers are just cautiously on guard, and are preparing intensively, preparing to set up a trap for the Spanish Armada in the North Sea, so that they will have no return, and in one fell swoop will crush Philip IV's last hope and make him surrender on his knees.

However, this time, Spain actually changed its previous proactive style and became a turtle with a shrunken head, and it could not come out of the port of Dunkirk, which simply shattered the glasses of the anti-Habsburg powers.

At the end of December of the Ming Empire, the port of Dunkirk finally moved, but it was not the Spanish Armada that came out, but a huge Ming Empire fleet entered!

This can frighten the anti-Habsburg alliance powers, is the Ming Empire going to war?

Naturally, the North Sea Fleet did not come to participate in the war, they were only ordered to build a corps to Northern Europe to repair pillboxes, and if the great powers did not take the initiative to provoke, they would not have dealt with the great powers at all.

The arrival of the North Sea Fleet can make the Spanish Admiral Oquindo very happy, to be honest, if he is allowed to take the Invincible Fleet to the vast North Sea to find the fleet of the anti-Habsburg Alliance, he is also a little worried in his heart, you must know that the five Invincible Fleets in front of Spain are all like falling into the evil, all of them have encountered a storm at sea, and he does not want to become the sixth unlucky ghost.

He raised his hands and feet in favor of the defensive and blockade strategy proposed by His Majesty the Emperor of the Ming Empire, and waited for the great powers to attack, and there were more than a dozen fortresses to support, this battle was not too easy, and he was 100% sure of defeating the combined fleet of the anti-Habsburg alliance!

He even asked Philip IV to give this joint defense line by sea and land a name, called the "Nordic Iron Chain", which means that the anti-Habsburg alliance powers were locked in Northern Europe and could not move, which shows that he had high expectations for this defense line, of course, there is a premise for really using the Nordic iron chain to lock the anti-Habsburg alliance powers in Northern Europe, and this premise is that the twelve fortresses promised by the Ming Empire can really be built quickly.

Now that the fleet of the Ming Empire has finally arrived as scheduled, how can he not be overjoyed, for this reason, he specially gathered the 40,000 troops of Spain and Portugal in the port, lined up in a neat phalanx, and held a welcome banner written in Chinese characters by the graduates of the Ming Academy, and came to a grand welcome ceremony.

Yang Geng didn't expect to see so many Chinese welcome banners in Europe, he took hundreds of guards off the ship and greeted Admiral Okundo for a while, and then ordered all the construction corps to get off the ship and prepare.

This Ming Empire is a cow, even the laborers who repair the fortress are unified Chongzheng clothes, and even their equipment is unified, of course, they are not carrying muskets, but shovels and shovels, each phalanx is a unified system, that formation, it looks even more neat than the phalanx of the Spanish Army, they also pushed a lot of exactly the same cart, but it is not a gun cart, but a simple flat cart, on which the iron bars, wooden boards, paper bags and something are also neat, I don't know what to use it for.

There are 100,000 people in the construction corps, and there are so many materials, it is naturally not a matter of time and a half to get off the ship, Yang Geng was not idle at this time, he directly took eight experts who built the fortress and invited Okundo to climb a small hill nearby.

Okundo didn't know what they were going to do, the eight experts who built the fortress took out the binoculars from their bosoms together, and glanced around, and it didn't take long for them to gather together and discuss in a whisper, and soon, one of them respectfully stepped forward and pointed to the four small mountain bags to report to Yang Geng.

After listening carefully to the report, Yang Geng asked directly in Spanish: "Your Excellency, how do you see the fortress cultivation here?" ”

Okundo roughly looked in the direction pointed by Yang Geng, the location is not bad, two by the sea, two by the inland, just around the port of Dunkirk in the middle, but he doesn't know if this distance is suitable, the artillery has a range, and the distance built is not suitable, so they can't support each other, so they can't stop the 200,000 army.

He hesitated a little and said, "Why don't we measure the distance first, this eye can't measure the exact distance." ”

When Yang Geng heard this, he laughed, he directly asked for the telescope from the person who reported it, stuffed it into Okundo's hand, and introduced: "There are scales on this telescope, they have already measured the distance, and there is absolutely no problem." ”

Okundo curiously raised the telescope to look into the distance, and there were indeed two crossed graduation marks in the lens, but how could the distance be accurately measured?

This is a little secret of the Ming army, Yang Geng naturally won't explain it to him, let them think about it slowly, he saw that Okundo didn't have any different opinions, he waved his hand directly, and said loudly: "Start work!" ”

When the eight experts heard this, they immediately hurried down the mountain, came to the phalanx of the construction legion, and pointed a few times, and soon, the 100,000 people of the construction corps were divided into four pieces, each led by two experts, and moved to the designated place.

Oquindo watched all this dumbfounded, this is too efficient, are they going to build a fortress right away?

He really guessed correctly, after the construction corps arrived at the designated mountain bag, they went straight to work, digging soil, looking for stones, carrying sand, carrying water, tree splint, tying steel bars, mixing cement, the division of labor was clear, orderly, and the appearance was as skilled as a farmer's farming!

Yang Geng saw Okundo standing there in a daze, and couldn't help but step forward and kindly remind: "Your Excellency, General, thank you for your warm welcome, can the army below invite them back to the camp?" ”

When Okundo heard this, he came back to his senses and said directly to the guards behind him: "Order, all the troops are collected and return to the camp." ”

The guards went to give orders, but he himself stood motionless, curiously looking at the four construction sites with binoculars.

After looking at it for a while, he suddenly realized a problem, these people didn't even go to collect stones!

He couldn't help but ask in amazement, "Don't you use stones to build a fortress?" ”

When Yang Geng heard this, he said proudly: "Our Majesty the Emperor of the Ming Empire has invented a magical building material, called reinforced concrete, which is harder than ordinary rocks, and we don't use stones at all to build the fortress!" ”

There is still such a thing in the world! Okundo couldn't believe his ears a little, and he muttered, "You don't need stones, can you fix it in a few days?" ”

Yang Geng replied without hesitation: "Five days!" ”

"Five days!" Okundo's eyes were about to burst, how could it be possible to repair four bastions in five days!
