Xu Wen's words are not long or complicated, but the priorities are clear, and the point of view is very clear.

When a thing is first created, there will always be a lot of problems, but it is a pity to choke on food.

When there is a problem, find the problem, and solve the problem, it is the right way.

Although Xu Wen is young, he really thinks clearly.

"Makes sense. Zhu Gantang said thoughtfully, "This kind of dispute is not because of the Moyi Palace, but because of the foundation of the country." Obviously, there are still many people who don't have a house to live in, and there are still many things to repair, so why are there people who can't find work and have nowhere to go? Why do so many people want a skill, but no one comes to learn it?"

He looked up at the sky, frowning in thought. The clouds rolled in the sky, the sunlight appeared and disappeared, and countless things seemed to rise in his eyes.

After a moment, he jerked his head down and asked left and right, "Do you have a pen and paper, I want to write a note!"

After saying that, he patted his head and realized where he was, so he turned around and was about to leave, as if he didn't take what was in front of him seriously at all.

"The election of the chief official has not yet been completed...... Jing Nanhai frowned and reminded him.

"I don't choose it! I can't compare to Xu Qian, it's him!" Zhu Gantang didn't reply, and interrupted directly.

This election is really strange, before the chief judge has scored, three people have already withdrawn, and now the remaining two people, one Li Quan and one Xu Wen, are all from the Inner Pavilion. It is equivalent to the victory of the Inner Pavilion without a fight.

Li Quan pursed his lips and looked at Xu Wen with a hesitant expression. At this time, Liu Wange took the first step to speak, and asked with a smile, "I'm sorry, I still have a question, I want to ask Brother Xiao Xu." ”

The front is still Xu Xian's nephew, at this time it is the little Xu brother, Xu asked a paragraph to give himself a generation.

"Master Liu, please speak. Xu Wen was still humble, and his attitude did not change in the slightest.

"The new city you designed is almost entirely two- and three-story stone buildings. This is to house more people, reduce the number of houses, and provide better ventilation and lighting. Very good idea. But this kind of stone building cannot be built without relying on Sanhe soil. I calculated that if you want to build this city, the amount of soil required is not a small amount, and it is difficult to achieve it with manpower and material resources. How are you going to solve it?" asked Liu Wange with a smile.

He spoke softly, but asked very practically.

No matter how good the design is, it needs to be feasibility.

What if you blow your design so well and can't build it?

As far as it seems now, if nothing else, this small second floor and small third floor are a big problem.

If the supply of Sanhe soil is not available, how can it be built in such a large quantity?

Even if the materials can, is it too late to smash the soil and raise the soil? How much manpower is needed?

Big problems everywhere!

This is not Nanyue, wooden buildings and bamboo buildings are a little easier to do. This is in the Western Desert, built in a stone building, not even a brick building, it seems that it is still a heavy thing like granite?

How can this be done?

Liu Wange said very sincerely, he was really worried about these problems.

Halfway through speaking, he turned his head to look at the presiding judge, as if to see if they felt the same way.

As a result, the other chief judges were okay, Jing Nanhai heard this question, leaned forward, and obvious concern and ...... appeared on his face Excited? It feels like I've been waiting for this question for a long time!

What does that mean?

For this question, Xu Wen has been prepared for a long time?

"I've thought about that. Sure enough, Xu Wen nodded and spoke.

He stepped aside, picked up a sack from the ground, and poured the contents on the ground, saying as he did, "It's a coincidence that I've been working on this thing with another friend and Yue Muxuan before I received the notice to campaign. ”

The sack, of course, is filled with cement, a gray powder that condenses when exposed to water, and produces a mud-like substance that glues the masonry together in a very short time. It can also be mixed with other objects such as sand and gravel and condensed into solids.

It is easy to obtain, easy to fire and easy to use, which has great advantages over triad clay and is the basic material that makes the design of the city possible.

With it, it is even possible to build higher-rise buildings with improved building structures, accommodate more people, and achieve more spacious and comfortable living conditions. However, due to the short time, I haven't had time to experiment one by one. In the future, of course, we will have to determine the security and certainty before we can practice it, and this time he didn't use that design here.

Xu Wen talked eloquently, and everyone in front of him, including Jing Nanhai, was dumbfounded.

Jing Nanhai saw cement when he was patrolling the field before, and probably knew what it was and what it was used for. But at that time, he didn't ask in detail, he just wanted to put the surprise until now.

But he really didn't expect that Xu Wen would give him such a big surprise!

If the utility and convenience of this kind of cement are so good, as he said, it can be popularized, and the architectural pattern of the entire Great Zhou will be changed as a result!

Jing Nanhai's mind turned sharply, his eyes swept over somewhere on the ground, and he asked quickly, "This cement can be used to pave roads?"

"Yes. Xu Wen directly paved a cement road in a certain section of the hot sample as a demonstration.

What can appear on the hot sample must be restored in reality, and he replied very simply.

"Can it be used to build bridges?" Jing Nanhai saw at a glance that a small bridge on the other side was not made of stone, but of cement.

"Yes. Xu asked.

In addition to being convenient and easy to use, cement also has a great benefit, that is, it is highly plastic. Different cement formulations can have different strengths and different application ranges. In fact, this is also consistent with its original Sanhe soil.

"Can it really be used in large quantities?" Jing Nanhai then asked.

"The cement formula is lime, clay, gypsum. After the new kiln and calcination method, the firing time does not exceed six hours in total. What is done here is a hot sample, and the volume is too small, so cement is used directly. In the actual use process, cement will be mixed with sand to make cement mortar, the ratio is about one to two, so that the amount of cement is smaller. Xu Wen explained very clearly.

"Three hours...... "Whether it's Jing Nanhai or Qin Lianying, everyone was shocked.

They looked at each other, and suddenly they all moved, squeezing next to the cement, some stretched out their hands to twist the mud to see its texture and even taste, and some directly lifted the shovel and began to mix the cement with the sand as Xu Wen said, and then spread it flat on the masonry to see how firmly it adhered to it.

Xu Wen stepped forward and taught them how to do it while continuing to introduce the other properties and uses of cement.

For a while, everyone, including the chief judge, including the craftsman who ran together, and even Li Quan, were shaken, and they were all fascinated by cement.

It is not surprising that when such a revolutionary material appeared, it would naturally have such a powerful charm.

After a busy moment, he stepped aside.

The old craftsmen didn't stop, they watched the cement gel at a speed visible to the naked eye, and they became even more excited, waiting for more results to come out, and they exchanged heads and discussed what it could be used for.

At this point, they completely forgot who they were, what the occasion was.

It can be said that as soon as the cement comes out, the results of this election will come out directly, and there is no need for the judges to score any more points!

Xu Wen saw this scene and smiled slightly, but the smile disappeared before it appeared.

Technology is important, but ......

Thinking of the discussion before the cement, he was more concerned about something else......

"You just say the formula, aren't you afraid that others will learn it?" Jing Nanhai didn't know when he walked up to him and asked.

"The recipe is very simple, and it's actually similar to the traditional triad soil. Our real technology is the firing method. Without it, there is no way to burn the finished product in six hours. Xu asked.

"You said you did it with your friends and Yue Mu Xuan?"

"Yes. ”

"Aren't you afraid that your friend will see the benefits?"

"He won't. This guy is weird, he doesn't care about anything but inventing new technology, and he even doesn't care a little ......."

Before Xu Wenwen finished speaking, someone suddenly walked quickly and saluted Jing Nanhai and said, "My lord, the few people you want have already been brought." ”

Jing Nanhai's eyebrows raised slightly, and he turned around and said, "Bring them over." ”
