"Weichen Yuwen Hu, welcome to the holy driver!"

Fortunately, Yuwen Hu had already come at this time, so there was no need for Bai Qing, a nine-rank petty official, to come forward. Pen ~ fun ~ Pavilion www.biquge.info Yu Wenhu Although he is from the third grade, he is also a member of the imperial court, he has a special position as a master craftsman, and he does not want to go to the court every day like ordinary courtiers, but occasionally when he is about to be a prisoner, Li Xiaojiu will summon him.

"Aiqing is flat!"

As soon as Li Xiaojiu entered the courtyard, he saw the standing cement slab, and after Yuwen protected it, he walked straight to the cement slab and turned around a few times, and also reached out and touched it, this cement slab looks similar to a stone, but it feels much rougher than ordinary stones.

An He beckoned to Bai Qing, Bai Qing immediately understood, and took out a bucket of cement powder from the warehouse where the cement was placed and handed it to An He, An He stepped forward with the cement and said:

"Your Majesty, please see, this is the calcined cement, in addition to the color, it looks the same as flour, as long as the water is mixed and poured into the mold, it can become a solid cement board after drying, of course, in order to save costs, it is generally added with some gravel and sand, as long as the proportion is appropriate and stirred evenly, the strength after condensation will not be reduced."

An He pointed to the cement and talked eloquently, although Zhang Xingcheng and others had known about cement for a long time, but after seeing the real thing with their own eyes today, they still felt very surprised, and although Chu Suiliang and others were pedantic, they also understood at this time, according to the characteristics of cement introduced by An He, they could also guess that there must be a lot to do with road construction, but what made them strange was that such an important matter, why should An and this teenage boy be responsible?

An He led Li Xiaojiu and the others to a freshly mixed cement pool and said:

"Your Majesty, please see, this is the cement mixed with gravel and sand, and after it dries, it becomes these extremely hard cement slabs."

As he spoke, An He instructed the craftsmen to dig out a few cement slabs on the ground that were almost dry.

"This cement is indeed wonderful, who would have thought that this flour-like thing, after adding water and sand and stones, would become like a stone."

Li Xiaojiu grabbed a handful of cement powder in his hand and said with admiration.

An He saw that Li Xiaojiu was in a high mood, so he picked up the big hammer on the ground and said with a smile:

"Your Majesty. Are you interested in smashing two hammers and trying the hardness of this cement board? ”

"Haha~, okay, let me move my muscles and bones today. Do you think that I was also the champion of the three armies back then, with my arms twisted, and at least hundreds of catties of strength? ”

Li Xiaojiu saw that An He was so funny, and he was also very interested at the moment, so he took the hammer and tried it. Then he picked it up and smashed it the stone slab.

"Huh~" Although Li Xiaojiu's strength is much greater than that of the underage An He, it is a pity that it is useless to the cement board that is half a foot thick, except for the more splashed fragments and the deeper prints, the cement board has no major damage at all.

"Huh~, this thing not only looks like a stone, but even its hardness is no worse than a real stone."

Li Xiaojiu was also very surprised, he really couldn't figure out why this flour was the same thing, after adding water and sand and stones. Is it really as hard as a stone?

"Your Majesty, the old minister also has some itchy hands, let the old man try it too!"

Cheng Zhijie, who likes to join in the fun the most, saw that this cement slab was so magical, and couldn't help but want to try it himself, he was a famous brave general in the Tang Dynasty, and the credit was all scored with a knife and a shot, if only about strength, he was much stronger than Li Xiaojiu.

"Okay, Zhijie, you can try it too."

Li Xiaojiu also wanted to see how hard the cement slab was, so he immediately agreed.

Cheng Zhijie didn't use the hammer in Li Xiaojiu's hand. Instead, he asked the craftsman to find him the largest hammer, the head of which was the size of a watermelon, and the handle of the hammer was the thickness of an adult's arm, and ordinary people really couldn't carry it. I really don't know what such a big hammer used to do?

"Phew~Bah~"

Cheng Zhijie spat on his two hands, and then slowly pushed the hammer to the top of his head, and then smashed it down with all his strength under the gaze of the surrounding civil and military officials.

"Boom~"

An He only heard a loud noise, as if a bomb had exploded in his ear, and his brain was buzzing. The same cement fragments splashed, there were many people close to dodge, the quick reaction with wide sleeves to cover the face, the slow reaction was the cement fragments of the face pain, the bad temper directly scolded on the spot, but unfortunately the skin is very thick, did not take everyone's scolding to heart.

When the dust cleared, and then looked at the stone slab smashed by Cheng Zhijie, everyone was surprised to find that the hammer head of the oversized iron hammer was actually embedded in the cement slab, and the surface of the cement slab was centered on the hammer head, and a big pit was sunk inward, but even so, the cement slab was still not broken, which was harder than many stones.

"Your Majesty, this thing is of great use, if it is used to build a city, it is not only fast and convenient, but also several times stronger than that built by bricks and stones, it is really a great weapon given to me by God in the Tang Dynasty!"

Li Shiji, who had been silently watching An He's performance since the beginning, suddenly stood up and said, the god of war is the god of war, and before An He said it, he had already seen the military value of cement.

Li Xiaojiu's eyes lit up after hearing this, he thought that this cement was only used to build roads, but after Li Shiji's reminder, cement should have other important uses, Anhe, this kid is really a god, and he has brought a lot of surprises to himself.

"Your Majesty, if you use this thing to build a road, then Jiannan will no longer have the pain of traffic, even if there is something, the army will come at night, and you can calm the chaos in one fell swoop, if you can replace the roads of the whole country with cement roads, then the traffic will be developed and the freight will be smooth, and all industries will be prosperous, and my Datang can also be more prosperous, so I ask Your Majesty for permission, even if it takes years or even decades, the cement road must be built."

Zhang Xingcheng is worthy of being the prime minister of the Tang Dynasty, with a long-term vision, beyond the reach of others, and he immediately saw the importance of transportation.

After hearing the words of Li Shiji and Zhang Xingcheng, the civil and military officials below were also discussing, some were admiring, and some were indecisive, but no matter what their attitude was, they all knew that this cement was definitely a good thing for the benefit of the country and the people.

"General An Zhonglang, there is something the old minister wants to ask?"

At this moment, an Anhe voice asked him the least like to hear.

"Oh? Lord Grandson, please speak! ”

Although he hated this yin man very much, An He had to take the other party's questioning. Li Xiaojiu and the civil and military officials also looked at the two.

"This cement is indeed wonderful, but I don't know how much it costs?"

The eldest grandson Wuji smiled slightly, and immediately asked the key. Li Xiaojiu and the others, who were still excited just now, also calmed down, and looked at An He with a nervous face, this cement is good, but good things are generally very expensive, if the cost of cement is too high, it will outweigh the losses.

An He smiled slightly, as a later generation, how could he not know the importance of the cost performance of goods, although he did not understand the materials and labor costs of cement, but Bai Qing, the principal, was clear, so An He beckoned to Bai Qing, and then said:

"The eldest grandson asked well, although the firing method of cement was provided by Anhe, but the specific operation was done by Bai Zhicheng, so he should introduce it to everyone."

When Chu Suiliang and others heard that cement was invented by An He, they were hesitant in their hearts, no wonder An He was responsible for this matter. (To be continued.) )
