Tang Jian only felt that the whole person was like falling into an ice cellar, and an indescribable cold rushed to his brain from the depths of his heart, and he was shocked by the cold sweat behind him!

The locust plague is not a secret, and the natural disasters of Datang for many years are not a secret, what makes him horrified is that Jieli actually knows that Datang is designing to deal with the Pearl Khan, and it seems that he was hijacked by them and he has long known his route. Pen, fun, pavilion www. biquge。 info

And what all this represents.... Datang and the Pearl Department did not hide everything from Jieli's ears and eyes!

However, all this is not the most important thing, the important thing is that he found that Princess Yicheng seemed to be like a poisonous snake, hiding in the shadows, as long as Datang was careless, he would bite off a piece of Datang's flesh and blood!

The sound of horses' hooves is still continuous, and the golden sunlight turns everything in front of you into a sea of gold. At night, there was already the neighing of cattle and sheep on the horizon, but Don was not in the mood to watch all the beauty in front of him!

......

Niu Jinda's eyes were about to pop out.

As the hammer of more than thirty catties fell heavily on the concrete that he had seen with his own eyes, it did not become torn apart as he thought, and not even a few wisps of sand and gravel fell.

He tried the hammer with his own hands, it was a good iron hammer, the black pig iron weighed twenty-eight pounds, and a handle that was half a zhang long made this iron hammer an invincible weapon on the battlefield, and even a war horse would be smashed to the ground by the power of this hammer.

And the person who used this hammer was also a personal guard he trusted very much, and his strength should not be underestimated, but even such a strong combination actually only left a heavy mark on the pier in front of him, which undoubtedly made his heart beat wildly!

You must know that the concrete pier in front of him, which did not look good, was made by Zhang Yi right under his nose, not only that, but even the whole process of air-drying was carried out in front of him.

It can be said that this concrete pier is clear in terms of materials, Cao, and even all the cattle entering and reaching. In his opinion, it is nothing more than a little so-called cement foam and a little sand and gravel, and then mixed with water and framed with wooden planks.

It's such a simple thing, but after it dries, it's as solid as a rock!

Not only Niu Jinda, but Xue Wanyan was also shocked, and his jaw was about to drop.

Although he had heard Zhang Yi inadvertently say two words about the magic of cement, it was just Zhang Yi's bragging, after all, this so-called magic was impossible in his opinion.

A little powder mixed with sand and gravel can become a strong fortress, so someone has to believe it!

"Little... Small... Boy, is this the trick you made? Taking a long breath of cold air, Niu Jinda's voice trembled a little, and he pointed to the cement pier in front of him and asked.

"I didn't make it, we made it together!" Zhang Yi smiled slightly, squatted down, carefully observed the situation after the attack on the pier and couldn't help but shake his head, and then said to Wang Lao Wu, who was looking up to the sky on the side: "Old Wu, come and see, you have less cement, right?" This piece is the skin that has been shattered by the hammer, and the proportion of sand and soil in it is less than three CDs, and the strength of the concrete made in this way will not be able to withstand it if it comes out dozens of times! ”

Suddenly, Wang Lao Wu, who was still stunned just now, immediately pulled down his face.

As one of the several major managers of Zhangjiazhuang, although he has always been in charge of the affairs of the village protection team, but before coming out, Zhang Yi carefully asked the group of craftsmen who fired cement to make up for his knowledge in this area, not only that, but among the people who came, there were even a few craftsmen who were also involved, and the purpose was that Zhang Yi could make some life-saving things on the march in order to prevent accidents.

Therefore, for cement, Wang Lao Wu is not familiar with its role and the methods used.

But... As Zhang Yi said, the current cement pier is obviously the lack of cement, although the mixing is very uniform, but according to Zhang Yi's requirements, the cement must reach more than forty percent for the general construction of the city wall.

After all, the cement fired now cannot reach the level of later generations in terms of purity or labeling, and since it cannot be reached, it can only be made up by quantity, so there is such a standard.

After all, it is not necessary to have even a little sloppiness in the construction of fortifications, and the use of roads is different, and the road is not repaired well, and if you don't pay attention, there will be cracks and the like, even if you don't pay attention, at most you will just fall on your heels.

But the construction of military fortifications is different, this is simply something that can kill at any time, if it is not strong enough, people casually carry a more and hit the wood is a slamming.... Then the city was broken, and everyone had to finish the game in the end.

For such a mistake, Zhang Yi didn't dare to be careless.

My son hasn't seen it yet, and the beautiful and happy life is still waiting for me to enjoy, if I give my life here because I used a little less cement, it will be a big loss.

"That uncle...."Wang Lao Wu's face became a little red, he also knew the power, he first looked at Niu Jinda and the others who were still in shock, and then whispered: "The gypsum we brought back last time was a little small, so the cement burned out is not much, and you also said that we still have to keep some kiln repair, and the rain made of soil in front of it will be wasted..... So I thought I'd save some money....."

Hearing Wang Laowu's explanation, Zhang Yi's anger did not come to one place.

But thinking about it still suppressed the anger in my heart.

Zhang Yi knows very well that from Wang Lao Wu's point of view, it is natural to save a little bit, after all, Shuofang is not like Chang'an, and it is a terrible thing to get some materials, take gypsum as an example, the place with gypsum mines is forty or fifty miles away from Shuofang City, and it is very troublesome to transport such a long way.

And that's not all, there is one of the most important reasons, and that is the lack of manpower.

You must know that although Wang Lao Wu is now in the team, and the twenty or so men in Zhangjiazhuang are also within his jurisdiction, even if these people are added together, there are more than 30 people, and this is to burn fire bricks and cement, so this person is naturally too busy.

"Don't make excuses for me!" Zhang Yi's face eased slightly, and he said with an iron face: "I can't understand a word, I mean just make some samples, and I didn't let you directly produce a large number of samples, as long as General Niu is satisfied with the samples, there will naturally be a large army to do it, otherwise you can still repair Shuofang City with those few people in your hands?"
