Yuzhou Island can be said to be the largest island in Jiangbei, the island is several kilometers away from the mainland, and it is farther from the mainland in history, because the Yellow River has seized the Huai, resulting in the strait shrinking day by day. In another half a century at most, the local gentry will continue to fix the sand little by little by ramming giant trees, and for a century, with the help of the sand brought by the Yellow River, the strait will be filled in, turning the island into a part of the mainland.

At that time, this was Lianyungang.

"When the world is calm in the future, we must move the Yellow River back to its original path......

Zhu Mingzhong, who was at the bow of the boat, secretly thought to himself that the reason why he once again rushed to Yuzhou Island by multi-pulp boat from the Qingjiang River was because of the intelligence from the north - the Qing army was planning to attack Keelung. And Keelung is the place where the families of those Shiqing officials are exiled and used as hostages.

In this case, sending a fleet to reinforce Keelung naturally became the only option.

"Shi Lang ......"

Thinking about this familiar name, Zhu Mingzhong's eyebrows raised slightly, although he didn't know much about the so-called "Haicheng Gong" Huang Wu, but he was no stranger to Shi Lang. After all, in later generations, this traitor was once touted as a "national hero", and even filmed a film and television drama related to him.

Zhu Mingzhong doesn't know what a national hero is, but how can a person who sells his own nation and defects to a foreign race be a national hero?

"This time, no matter what, you can't let him go!"

Thinking that this traitor had finally destroyed the last ray of hope for orthodox Chinese civilization, Zhu Mingzhong's heart welled up with anger.

Don't let him go!

However, it seems that compared to Shi Lang, there are not many people on his side who are good at naval warfare. After all, the current Zhongyi Navy has only just been trained for a few months, and at most it has just gone to sea, and in contrast, Shi Lang and his fleet are not only good at navigation, but also have a brilliant victory in the Battle of Liuluo Bay.

With such a new navy, will it be possible to defeat those veterans at sea?

"We don't have a choice!"

Qian Lei looked at the thoughtful Jing Xiao and said.

"If the imperial court is placed in Taiwan, the more than 10,000 sailors under the command of Huang Wu and Shi Lang are the biggest enemies of the imperial court, if they are stationed in Fujian Province, they will inevitably threaten the imperial court from time to time, and if they are not solved, the strategy must be heavily garrisoned in Keelung, so that Keelung is a burden in terms of the strategy!"

Qian Lei, who is Zhu Mingzhong's confidant, may not be the most talented, but he is undoubtedly the most loyal staff member, and of course one of his most trusted confidants. Compared with the uprightness of Zhu Daxian, Gu Yanwu and others, Qian Lei has a lot of means.

And taking the opportunity of exile of the Shiqing official family in Taiwan, forcing the Manchu Qing to force Huang Wu to attack, it was his plan, although Qian Lei was not a soldier, but he knew very well that Keelung was one of the most important links in the plan. Not only the sulfur there, but also the sugar and rice that will be produced there in the future. Rather, it will be placed there in the future, and not many people know that the court will be placed in Keelung.

On the surface, this was done to avoid conflict with Zheng Chenggong, and on the other hand, it was also to "coerce the princes of the Son of Heaven". And Qian Lei also knows that Jinglue's choice is not just a Yongli, in addition to the imperial court, Jingliu has been in contact with some clans in Nanjing, plus the identity of the "clansman" who has not yet been determined, it can be said that in the future, Jinglu has too many choices. Qian Lei doesn't know what other people think about all this, but in his opinion, the more Jinglu is like this, the more he will follow Jinglu with all his heart.

After all, people always have selfish intentions!

Qian Lei never wants Jinglu to become a loyal minister of Yue Fei's style!

"I know ......"

Nodding, Zhu Mingzhong looked at Yuzhou Island, which was getting closer and closer, and said.

"If I didn't know the necessity of this matter, how could I instruct Sishi to plan this operation, it's just that our strength is too weak!"

Yes, too weak!

It was even because of the weakness that in order to gain a foothold in Keelung, an agreement was reached with the Dutch, thus avoiding conflict for the time being. And how long can such an agreement last?

I'm afraid only God knows!

"It's unpredictable!"

In the exclamation, Yuzhou Island was already in sight, and the first thing that caught my eye was the towering brick-red chimney of the wheel kiln factory on the seaside, where thick black smoke was spewing into the air.

This towering brick-red chimney is so proudly erected in the green mountains and green waters of Yuzhou Island, for Zhu Mingzhong there is no sense of disobedience, and the wheel kiln factory to a certain extent, means the foundation of an industrial civilization.

The first wheel kiln factory was born in Qinghe last year, and now the buildings in Qinghe are all red brick buildings, and the wheel kiln factory is not only a brick factory that produces ordinary red bricks and refractory bricks, but also a cement factory. Originally, the manufacture of cement was not in Zhu Mingzhong's plan, after all, in the face of pressure from Dasu's 100,000 Qing army, he had no time to consider cement and other basic building materials, until after defeating Dasu, when the loyal army began to build a military camp, in the face of the shortage of bricks, Zhu Mingzhong immediately thought of a wheel kiln brick factory with higher production efficiency. It is a continuous kiln designed by the Germans in the mid-nineteenth century, although in the twenty-first century it is a backward thermal equipment. However, in this era, it is a very advanced design, and has the advantages of continuous production, high output, can use various fuels, and low construction costs.

It was also thanks to the establishment of several wheel kiln factories that the loyal soldiers lived in brick barracks before winter, and of course, another function of the wheel kiln factory was to produce cement. From the beginning, Zhu Mingzhong's idea was to simply burn a substitute cement to meet the construction needs of factories and military camps. This kind of cement, also known as "brick and tile gray cement", was used in many rural communes before the 80s. Its production does not require complex equipment processes, and the production process is extremely simple, that is, to grasp the bricks or pottery to crush into powder, and then add lime and gypsum, which can be used directly.

The reason why I knew that there was this thing was because I had heard my father mention it, because the old house in my hometown was built with this kind of cement, because it was difficult to get industrial coupons to buy cement at that time, so Zhu Mingzhong didn't know much about this kind of substitute cement. That's why the burned red bricks were transported to the yamen for experiments. Instructed the handymen in the house to break the bricks into small pieces one by one, and grind them finely, Zhu Mingzhong naturally thought of the stone mill, but in the end he found that the work efficiency of the stone mill was not very high, but it could barely be used for experiments.

After grinding the bricks into fine powder and sifting them, Zhu Mingzhong mixed the brick powder with lime, then added water and mixed well, and under the confusion of the soldiers and officials of the government office, the "cement" was used to build a brick wall. And Zhu Mingzhong is also full of expectations, after all, he also wants to see with his own eyes whether this legendary cement is really effective. Although the old family of the old family is built with this kind of cement.

The end result proved that the cement was fully usable. Although it is not comparable to Portland cement, it can be used as a binder for building materials and even as concrete. At least it is a little stronger than clay mixed with loess lime.

The brick factory on Yuzhou Island is more mainly used as a cement factory - in addition to being used as a binder for building materials, the forts and other places on the island are all used concrete, and it is not simple concrete, but by adding bamboo reinforcement to concrete, increasing bamboo reinforcement can enhance the tensile force and compression resistance of concrete, this is because there is no steel bar as a last resort, and compared with steel bars, bamboo has strong toughness, good tensile and compression resistance, which can enhance the integrity of concrete. However, the bamboo tendons selected have undergone careful anti-moth treatment, and there are detailed operating procedures when pouring concrete, such as air holes must not be left during operation, and the bamboo tendons must be arranged very finely.

Because of this, the forts of Yuzhou Island and Liandao are much stronger than the forts of this era. When the ship enters the port, you can vaguely see the fort located on the hillside, the fort made of concrete and boulders, it looks very powerful, the muzzle of the black hole along the gun, pointing directly to the sea, when the fort defense system of the two islands is completed, there will be more than 300 guns of various specifications from 9 catties to 24 catties, and even in the entrance of the harbor, there is a standard star-shaped fortress.

"Jinglu, if Keelung can have such a fort, when the time comes, Keelung will naturally be safe!"

Qian Lei's words made Zhu Mingzhong say with a smile.

"Impossible!"

Shaking his head, Zhu Mingzhong pointed to the unfinished fortress at the entrance of the harbor and said.

"Not to mention that it takes a lot of money to build such forts and forts, even in terms of time and manpower, with the current conditions of Keelung, it cannot be met, don't forget, even if we have invested nearly 10,000 laborers in Yuzhou Island, it will still take at least two years to complete these forts and forts, and the reason why we have invested so much energy and financial resources to build forts and forts here is because Yuzhou Island will be our naval base camp in the future, at least one of the base camps......"

Looking at the shipyards, docks, and harbors on the shore, all kinds of ships, although there were only about two dozen real warships, Zhu Mingzhong's eyes still looked a little excited.

Navy, this is my Navy!

There will be no more trolls!

There is only a navy, and this navy will set sail here and sail to the sea that belongs to them!

"Navy?"

Qian Lei's puzzlement made Zhu Mingzhong nod and said.

"Yes, from now on, there will be no more loyal and righteous navy, only the navy! Only the naval fleet of the Loyal Army! ”
