"I just wanted to destroy this stone wall in half an hour? However, it would be a bit difficult to destroy this thing with just these manpower and these equipment. Not to mention half an hour, they wouldn't be able to do it even if they gave them a day."

Wang Yang whispered as he looked at the Song Dynasty imperial guards demolition teams who were busy smashing the wall.

It’s not that I despise them myself, but that this stone wall is really hard to destroy. After all, even if this thing is a weakened version of reinforced concrete, it is still a thing that is extremely difficult to demolish.

Even if the demolition team in later generations wants to demolish cement columns and stone pillars. When cement structures, they must use large dismantling machinery. Otherwise, if they want to demolish them manually, it will be difficult to kill a three-foot square cement column in ten days and half a month.

What's more, this is not a column, but a cement wall with a thickness of one meter. Even if it is a large machinery with an internal combustion engine, it is probably necessary to take a lot of effort to remove this solid and honest wall.

Seeing Wang Yang chatting and laughing with Chen Andao so relaxedly, he didn't care about the exhausted and stinky soldiers tinkering with the stone wall there.

Zhao Xu couldn't help but breathe a sigh of relief, and he couldn't help but feel anxious. After using cement, the pebbles that were slippery and slippery became almost completely a whole, and were so strong and resistant to smashing.

I am afraid that the city walls that were built with blue bricks were not so powerful. When I thought that if the border forts in the northern border of the Song Dynasty were so strong, then how could those Western Xia and Liao Kingdoms have the opportunity to easily break the border forts in the Song Dynasty?

Well, two quarters of an hour have passed, and the wall is still standing strong. Can't it be explained?

Although the soldiers of the imperial guards still did not give up, it was enough to see from the bumps that were knocked out that even if they were given half an hour, the stone wall would not fall down.

Although everyone could see that the continued success of the imperial guards was just in vain, everyone still waited patiently until the end of half an hour.

In the end, the imperial guard general who had just stepped barely to push the city cart and hit the cart could only helplessly walk to Gao Taotao and hand over the order. "I apologize to the Empress. This stone wall is too strong. Unless I wait for another day, I am afraid that I will not be able to destroy it at all."

Gao Taotao's eyes fell on Wang Yang and asked, "Wang Qing family, what are the defects of this cement? Can there be any way to make it collapse in the shortest time?"

"This, Weichen has no good idea. He can only continue to use brute force to damage it. After all, this is not a mud wall, and he is not afraid of water at all. As for fire..." Wang Yang was also helpless. What kind of thing in later generations is construction waste, and cement slag is construction waste.

"And, even if you are smashed, if you use these scraps and add the mixed cement mortar to repair it, you can almost be said to be able to achieve the state of integrity after the shade is dry."

"...So that's it." Gao Taotao nodded, no longer asked Wang Yang, but instead looked at the dejected general of the imperial guard.

"It's okay for General Li. Since it's not possible in half an hour, then you will continue to find a way to smash the wall and push it down. The Ai family will give you the reward you promised. You guys, let's go." Gao Taotao said, looking at the wall that was still standing even though scars were everywhere.

Well, this thing is indeed very solid, but the problem is that this place is outside Yuehua Gate, which is usually an empty square outside that Rihua Gate, but now there is such a stone wall here, and it feels too disharmonious if it is not destroyed. The important thing is that it hinders the Feng Shui of the Song Dynasty royal family.

The imperial guards were left behind and they asked them to find ways to become demolition teams. A group of civil and military ministers followed Gao Taotao back to the Wende Hall.

The ministers had already come back from the shock just now, but everyone's eyes when they looked at Wang Yang were filled with envious or jealous eyes.

How old is this kid? He first created a Yuanyou printing technique that caused a sensation in Bianliang. Now, although Yuanyou printing technique has not been promoted yet.

However, the speed of printing books in the Royal Commercial Press, even if the Royal Commercial Press currently only accepts orders from the court, really made the bookstore owners in the entire Bianliang area frightened.

The books in the hands of booksellers have begun to fall in an orderly manner. In the past, the Analects of Confucius, which required five cents of money, has almost fallen by one cents of money.

The scholars praised it, thinking that it was the credit of Yuanyou's printing technology, but they didn't expect it. Yuanyou's printing technology had not spread yet. If the emperor announced the announcement of Yuanyou's printing technology, he would not know what level the prices of those books that were extremely cherished in the past would fall.

It was precisely because of the protection of the printing industry of the Song Dynasty and Wang Yang's persuasion that the Song Dynasty could print a large number of Buddhist scriptures and other things and secretly sold them to the Xixia and Liao Kingdoms to make money. Only then did the emperor agree to continue hiding Yuanyou printing technology first.

Not to mention Yuanyou printing technology, just talking about Yuanyou cement, its strength actually exceeds the cognition of the old corps who have been to the Sand City Battle.

It is believed that once this cement can be applied to the construction of border villages and forts in the Song Dynasty, it will inevitably make the border villages of the Song Dynasty as solid as a soul.

In the absence of cavalry in the Song Dynasty, being able to defend against the enemy with its strong city defense was originally what every military general of the Song Dynasty most wanted to see.

“Does this kind of thing need to be boiled beforehand?”

"No, you just need to transport it to the construction site, add a certain proportion of moisture and sand and gravel, and mix the lime."

"In addition, in addition to this kind of cement, there is another fast-drying cement that can speed up the solidification rate by about half. It is most suitable for use in emergency construction projects, but the firmness of that kind of cement is worse than this."

"You mean, two pounds of cement like this cost three cents? Then how many pounds did you spend on building this section of the city wall?"

"It's about 300 kilograms. It's about 900 jin."

"Does this thing have no disadvantages?"

"Yes, that's why this Yuanyou cement is not resistant to moisture, so it must be packaged and transported in an oil paper bag. After use, it is best to tighten the bag mouth so that the moisture in the air will enter. Otherwise, it will be easy to dry and tie together, just like a complete stone."

"The north has always been bitter and cold, and there is no need to worry about being too wet in that place." said a general who once lived in the northern border.

"Another reason is that it needs to be mixed with water and mud when used, so it cannot be used when the weather is too cold and freezing. In that case, the moisture will precipitate and cannot be fully mixed with the Yuanyou cement and slowly solidify."

"This is a trouble..."

"What's the matter? No matter how cold the north is, it will only take three or four months to freeze. As long as the construction starts in the cold winter, it's all done."

Ministers after minister raised questions, while Wang Yang responded one by one without any panic. Zhao Xu was very satisfied. He was so happy to listen to the questions and answers between Wang Yang and the generals who were familiar with military strategies.

What kind of talent is called talent, the pillars of the country, and the talent of the country. Look at the article "Theory of Youthful China" produced by others with a beautiful literary talent, I don't know how many young people use it as a life motto for self-proclaiming themselves.
