But now the biggest difficulty is the opposite Dayi Ningguo, if my side starts to build, the other party will definitely get the news as soon as possible, I am afraid that my pass has not yet been built, and the iron hooves of Dayi Ningguo have come to Ningzhou City.

But I still have a mature idea, the current outpost is too small, and there is no time to react when encountering the enemy's situation, and these dozens of people can easily be crushed by the enemy's iron cavalry.

Before the pass is built, I plan to upgrade the outpost here and set up a 300-person inspection department, which can be regarded as laying the foundation for future plans!

I casually handed the telescope to Jian Zheng beside me. Jian Zheng hesitated for a moment, then carefully took it and put it in front of him like me.

He just glanced at it and let out a whoosop that nearly threw my telescope down the valley.

His look of surprise and trembling cheeks told me that he had been completely shocked by what he had seen through his binoculars.

Next, Jian Zheng happily held the telescope and kept changing directions, like an ignorant child who got a novel toy, and couldn't bear to let go.

The people next to him didn't know how Jian Zheng could become like this, and they had already been completely confused by his actions.

In this era of cold weapons, the role of having a telescope is undoubtedly huge, when the other side sends scouts to investigate, we can observe the enemy's every move with higher efficiency and the fastest time, and understand how the enemy arranges the troops.

Seeing Jian Zheng holding the telescope to look left and right, he didn't see enough, and this aroused the curiosity of others.

But Jian Zheng occupied the telescope alone, and the others couldn't bear it, so I had to smile bitterly and do it myself, and finally snatched the telescope back from Jian Zheng's hand, and then handed it to Lin Yi. Next, after taking turns to watch it, everyone was already full of praise.

I couldn't help but laugh secretly, this is a huge difference across generations, what I see through the telescope can be so detailed that they can't figure it out even if they want to break their heads.

While everyone was shocked, they asked what kind of treasure this was, and why they could see so far away.

I had no choice but to fool them and say that this was a Western clairvoyant, which was given to me by a strange man who did not know its origin, and gave me the method to make this clairvoyant, and in the future I will make it in large quantities and equip it with the senior commanders of the army.

Although everyone didn't dare to open their mouths to ask for the one in my hand, but when they heard that I could make a clairvoyant mirror, they were all cheeky and under various banners, begging me to equip them with one no matter what.

In fact, it is not difficult to make a simple telescope, as long as you have a high-quality concave and convex lens, it is quite easy to make. However, under the current conditions, it is not easy to make a telescope with good performance and completely meets the requirements.

Because in this era, although in the Mediterranean region there were already relatively primitive glass products, and sold all over the world. However, at this time, glass can only be called colored glass, and its diopter and purity are far from meeting the requirements for making telescope lenses.

So I can only make a plan and move forward step by step. As long as I have enough time, my next step is to produce high-quality glass first, and continuously improve the production process and level of glass, and finally make a telescope that basically meets the requirements.

This should not be a difficult task for me, a bioengineering graduate, except for finding the right materials and improving the production process, nothing else is a big problem.

At noon the next day, Lin Qingliang rushed to Ningzhou, and at the same time brought a large cart of limestone for making cement. I immediately put down the work at hand, invited Lin Qingliang to the study of the Xuanfu Embassy, and seriously discussed with Lin Qingliang the production method of cement.

In fact, in my later life, I once had some understanding of the production methods and processes of cement through a friend in the cement industry, but after all, I had not practiced it myself, nor had I participated in this work, and I had no clue about the specific development details.

So I want to know what are the advantages and disadvantages of Lin Qingliang's production method and later generations, so that I can learn from each other's strengths.

Through Lin Qingliang's tireless detailed introduction, I gradually understood his so-called cement production method.

Lin Qingliang's cement production method is actually very simple, that is, the limestone is crushed and the clay is calcined in the kiln, and then the cement clinker can be used as cement after cooling and drying, which is still the most primitive cement production method, and the performance of cement is not very stable, at least the strength and uniformity of cement can not be reached.

However, if according to the simplest modern production method, an appropriate amount of iron ore and pulverized coal should be added to the raw meal, and only after air drying can it be put into the kiln for calcination, and part of the gypsum powder should be added to the clinker out of the kiln after cooling, so as to become the final Portland cement finished product.

In fact, if you want to make fully qualified cement, you also need to have a lot of conditions and equipment, such as modern vertical kilns or rotary kilns, mills, fans, etc., all links are indispensable, and our conditions are far from being reached in materials and equipment alone.

However, now that we have high-quality raw materials, there is no problem in making basically qualified cement.

Although there is no ready-made machinery and equipment, we can make some manual equipment as simple as possible, as long as the manufacturing process is relatively perfect, the quality of the cement produced is not much worse.

Although there are more people hired because of this, there is no shortage of manpower this year, and more manpower will be done.

After a detailed discussion with Lin Qingliang, our idea of making cement has also become clear. The first thing we need to do is to study and install a vertical kiln that basically meets the conditions.

Although there are no ready-made drawings, but according to Lin Qingliang's previous kiln to improve, the combustion chamber and ventilation can be optimized, although it may not fully meet the standards of modern vertical kilns, but I believe that after continuous exploration and improvement, we can finally have a completely suitable vertical kiln.

Then there is the issue of the production process. After continuous communication between me and Lin Qingliang, the standard production plan was finally temporarily determined. It is to crush and dry limestone, clay, iron ore and pulverized coal according to a certain proportion, and then select the appropriate temperature in the kiln to calcinate, and after reaching a certain time and heat, the clinker produced is cooled and mixed with a certain proportion of gypsum powder to become real cement.

Although there are still some technical problems such as combustion temperature and time, blending ratio and mixing method that have not been finally solved, I believe that with Lin Qingliang's ingenuity and my careful guidance, after a period of testing, the qualified cement will be successfully tested.

After my non-professional pointing, Lin Qingliang felt deeply benefited, and my suspected authoritative opinion also brought Lin Qingliang a lot of shock, he couldn't believe that I, the champion of the big man, was so good at making cement, and the advice I provided was so reasonable, he couldn't help but admire.

Once the technical issues have been agreed, the next step is to set up the organizational structure. I have already thought of the name of this pass, opposite is Songyang County of Dayi Ningguo, our pass is called Pingyang Pass, who calls the king of Dayi Ningguo surnamed Yang!

In addition, I decided to immediately set up a public works bureau in charge of the construction of the project, and the bureau will be temporarily held by Li Hui, a sergeant who is familiar with civil engineering, to take full charge of the design and construction of Binh Duong Pass.

But at present, it can only be in the design stage, and all information cannot be made public. The most important thing now is the design and construction of the cement factory, and when the cement quality is stable and large-scale production, we will look for the right time to build this Binh Duong Pass.

The reason why Lin Qingliang was not allowed to serve as the head of this bureau was because I was still a little selfish. I don't want him to be too involved with the government, and I plan to build a large restaurant in the future, and it is most suitable for him to manage it privately, but it is inconvenient if he has an official position.

Some of the craftsmen who built the pass were brought by Lin Qingliang, and the other technicians were recruited by the government and handed over to Lin Qingliang for management and use, and all the costs were borne by the government.

Moreover, I also selected 300 of Sun Decheng's tooth soldiers who were imprisoned and handed them over to Lin Qingliang as miscellaneous servants, and he arranged for them to be used. In addition, in order to prevent these prisoners from taking advantage of the opportunity to make trouble or escape, I arranged for a conscientious and responsible lieutenant to lead 100 soldiers to be responsible for the safety and security of the construction and production of Binh Duong Pass and the cement factory, as well as the supervision of prisoners.
