In the absence of kinetic energy such as gas and electricity, and the power of humans and animals is everything, it is unimaginable to realize automated production.

The same is true for fired cement.

Fortunately, with precise design, a certain degree of automation is still possible.

This is the case, for example, in cement kilns where cement is fired.

Using the inclination and size of the firing chamber of the cement kiln, and then using gravity, the cement kiln realizes the whole process from feeding to firing and discharging, which can be continuously circulated, without waiting for the kiln body to completely cool down after the cement is fired in each kiln, and then firing......

This design greatly improves the work efficiency.

Although such a design is easy for anyone with a little knowledge, it is enough for any people of the Tang Dynasty to surprise them.

It is also for this reason that since several cement kilns began to fire, there has been an endless stream of people, ignoring the amount of smoke and dust at the time of cement production, crowded in any corner where the production process can be seen, and watching the factory fire cement with fascination......

In the past ten days, the grass and trees on the high ground around the cement plant have been trampled flat, and there have been more than a dozen accidents in which people accidentally fell and were seriously injured while climbing trees to watch.

This kind of ending was obviously something Wei Ming didn't expect.

However, Wan Dongsan, Zhang Shi and others, who have now become cement firing people, are full of a sense of achievement, not only every time they command the firing, but they can't help but stand tall and shy when they walk in front of people, and show their majesty to a certain extent as much as possible......

A certain degree of automation using gravity inertia design ensured the availability of cement products, and the pouring of dams was also put on the agenda.

While the bundling of steel bars and carpentry formwork were being carried out, the world's first cement road was gradually extending from the cement factory to the working face of the dam......

Looking at the smooth and smooth cement road of less than a kilometer, I thought of how much time, manpower and silver would it take to pave such a long section of cement road entirely with bluestone......

Now, it only takes about 100 people to complete it in just a few days......

After the cement road was dry and hard, Li Jiao walked back and forth along the cement road almost with tears in his eyes, and he walked more and more energetically, and he didn't feel tired at all!

If it weren't for Wei Ming and the others who were afraid that Li Jiao would be tired and would stop him stiffly, this guy would be able to walk back and forth all day.

On November 7, the tenth year of Tianbao, the beginning of winter.

In the early morning, gongs and drums are noisy and firecrackers are ringing out.

"Start pouring!"

With Li Li's high-spirited roar, hundreds of wheelbarrows rushed to the working face, pouring a truckload of cement into the dam body supported by wooden planks......

With the continuous accumulation of cement, the dam gradually rises......

"Almost!"

Wei Ming nodded slightly at Chen Dong.

"Follow me!"

Chen Dong, who had been waiting for a long time, waved his hand fiercely, and jumped into the cement two or three feet deep with a bamboo pole like a charging soldier, and carried out artificial vibration to remove the bubbles in the cement.

One day of pouring, three days of waiting.

Three days later, when the outer wooden mold was dismantled, a gray cement dam with a length of 600 meters, a height of nearly one meter, and a width of more than 10 meters was presented in front of everyone.

"Smash!"

With a low roar, hundreds of people rounded their arms and smashed them fiercely with sledgehammers!

On the hegemonic body, only shallow white marks were left, but the hands of the strong men themselves were numb.

"Great, I didn't expect this cement dam to be much stronger than I expected!"

Seeing this scene, Li Jiao was excited to think that the use of cement to pour the dam not only saved countless materials, manpower and manpower, but also built so fast and the dam so strong......

If Li Heng hadn't explained that he would wait until the dam was completed, he would have gone straight to the imperial city and would have reported this unprecedented miracle to Li Longji in person!

Li Jiao is so excited, let alone someone else?

Everyone danced happily, except for Wei Ming.

After all, the construction of such a large cement pouring project is not much more difficult than that of rural villagers building a house thousands of years later......

Therefore, compared to everyone's excitement about building a hegemon, Wei Ming was wrapped in clothes pressed by felt cloth and trembled and found Li Jiao, Zeng Fanzhi and others, saying that because the weather was too cold, he occasionally contracted the wind cold, and he needed to take leave to go back to Chang'an to recuperate!

"There is a charcoal stove in the waiting room day and night, and this will also catch the wind cold?"

Zeng Fanzhi, Wu Dong and others laughed strangely, Li Jiao said in a kingly style: "In less than March, the cement factory dam has already been quite large-scale, Xiaolang has worked hard, and if he wants to go back to Chang'an to relax, he doesn't need an excuse - this king is not such a harsh lord......"

Wei Ming naturally couldn't change his words because of Li Li's words, biting himself to death was really infected with the wind and cold, and at the same time he also pulled his clothes and said that wearing this body was thick and heavy, as if he had a pair of armor......

But the crux of the matter is that no matter how much you wear it, it won't keep you warm, and it's hard to keep yourself from getting sick!

"Except for King Ping, what you wear with Xiaolang is the same thing!"

Zeng Fanzhi and the others secretly rubbed their hands and sarcastically said: "You don't feel cold at a certain age, why are you so delicate?" ”

Wei understood his eyes, and said in his heart that you don't feel cold, that's because you have always spent the winter like this, but I'm different!

For decades, I was either wearing a thick cotton down jacket or staying in an air-conditioned room!

Wearing this body coldly blowing cold wind in the open air in this cold winter wax moon, it is a strange thing to be able to bear it!

However, after Li Jiao heard the words of Zeng Fanzhi and a few others, his expression was thoughtful......

Anyway, Wei Ming's leave was finally successful.

He successfully took a leave of absence, and naturally there were many people who were wiped out together, such as Hu Lijun, Zhang Ziyu and others, who had been away from home for more than two months, and they were able to follow back to Chang'an to see their long-lost family members by escorting Wei Ming.

After more than a month or two of training, Wei Ming's horse skills have greatly improved, although he still can't gallop like Wan'an Zhang Ziyu and others, but he trots all the way in a flat place, which is enough......

It was also because of this that it originally took a whole day to get from Fengpangu to Chang'an, but now it only took half a day for a team of people to return to the city.

Wei Ming had just stepped into the house with his front foot, and the people from the Prince's Mansion with his back foot had arrived!

"I have a meritorious role in building the cement factory dam, and I know that I am young and frail, and I can't withstand ......the wind and cold."

The man in his forties smiled all over his face, and said sharply: "Your Highness has an order to give you a few pairs of high-quality furs, and make a few clothes for the prisoner to keep out the cold......
