The formula of cement can indeed be easily found on the Internet, from material compatibility to engineering design, which is very detailed.

But Xu Wen didn't go back to Banmen World with this in mind, but called Lu Lihai to find a cement factory to take a look at the site.

Lu Lihai with such a large construction team as Banmen, there must be a way, and it is most convenient to find him for help.

As a result, I didn't expect Lu Lihai to be at the Wenchuan Conference, and there was still a little worry in his voice.

Xu Wen asked about the situation clearly, pondered for a moment, and went directly over there.

Wenchuanhui and Xu Zhai are on Quhe Road, not too far apart, and Xu Wen walked for more than ten minutes to arrive.

When he walked, Lu Lihai was waiting for him at the door, and when he saw him, he still looked a little worried.

"It's still noisy, it's endless. He greeted Xu and shook his head.

"What is it about?" Xu Wen only knew a rough idea on the phone, and he didn't know the details.

And there is one thing he also thinks is very strange, according to what Lu Lihai said on the phone, what the Wenchuan Society and the Banmen are doing now is the "identification" of a certain skill, and it is also the most basic judgment whether it exists or not.

However, stone is different from wood, and its preservation time is much longer than that of wood, and stone products that are more than 1,000 years old can often be preserved intact.

The work is the carrier of the skill, whether a skill is feasible or not, just see that there is no such finished product, where is the use of arguing?

"About the ...... of the Beamless Hall What's wrong?" Lu Lihai mentioned it casually, and turned his head strangely to look at Xu Wen, who suddenly stopped.

“...... It's nothing, I just think some things are too coincidental...... Isn't there an existing example of the Beamless Palace? What is there to discuss?" Xu Wen took another step forward.

"You're right, there are ready-made examples of the Beamless Palace, so the teachers are not doubting whether it can be built, but questioning whether the method recorded in the Zongzheng scroll is feasible. After all, it is also a beamless hall, which can be built with method A, or it may be no problem with method B. Lu Lihai said.

Quite so. Retrospective from the finished product is possible, but limited. If that technique is vaguely documented, it is normal for people to be questioned.

However, in this case, you have to actually see the details to judge.

The two quickened their pace and arrived near the small building together, and before they entered the door, they heard a fierce quarrel, Lu Lihai smiled bitterly at Xu Wen, and shook his head: "The noise is even more fierce than just now!"

"Isn't Elder Luo here? he doesn't care?" Xu Wen glanced inside and asked in a low voice.

"I went to him in the earliest days, and he said that he did not know the truth, and let them go. Lu Lihai laughed even more bitterly.

"Hahahaha. Xu Wen laughed, he saw that Lu Lihai still had a sad face, and comforted, "Don't worry, there is a theoretical school over there, and you are actually doing your work, if you really fight, they can't beat you." ”

"Is this what I'm worried about!" Lu Lihai was so angry with him that he shouted quietly, but after such a casual joke, his mood relaxed a little, and he was no longer as tense as before.

Xu Wen didn't go in immediately, but stood outside the window to listen to the quarrels and exchanges inside, summarizing the information on both sides.

As he listened, his expression became more and more strange, and finally he turned his eyes and stared at the constantly moving mouths of the old people in the window, and he did not move.

"If it was carpentry, it would be good to find you directly, you said it, how convenient it is. But the beamless hall is purely made of bricks and stones, at most a false roof is added with wood on it, and nothing else is sticky, so you can't help it......" Lu Lihai was still worried, chattering.

"That could be...... There's still something about it. Xu asked.

"What?" Lu Lihai looked up suddenly, startled.

"I happened to be working on the Beamless Hall recently, and now it sounds like there is something in common with what they're talking about. Xu asked.

In fact, he was also surprised by this.

He hadn't been standing outside for a long time, and he hadn't heard a lot of content, but after a while, he could already hear it, and what was being discussed inside was exactly what he had been pondering recently!

Beamless halls are no longer unusual, and the presence of reinforced concrete makes wood no longer necessary.

But in those days, there was no reinforced concrete, there was no cement, and there was not even enough triad earth as a binder, so how could masonry be used to build a huge building of palace mass?

There is an answer on the incomplete drawing given to him by Luo Da, and in addition to this, Shi Guangming's legacy also provides another part of the answer.

Xu Wen came back to seek the formula of cement and wanted to make cement in batches in the Banmen world, but this did not mean that the original skills could not be used.

And now what the elders of the Banmen and the experts of the Cultural Communication Society are discussing is the finished product that he once thought of combining the two skills without using cement, a method that integrates multiple directors to complete the beamless hall......

It's too much of a coincidence.

It may also be a coincidence that it is a wonderful relationship between the two worlds, a mutual projection......

At this moment, Xu Wen felt a huge, mysterious existence descending and enveloping him.

Once again, he realized the wonder of Xu Zhai.

"Let's go inside. He said to Lu Lihai.

As soon as Xu Wen and Lu Lihai entered the door, the voices inside gradually stopped.

The experts of the Cultural Communication Society knew Lu Lihai, but they didn't know Xu Wen, and after looking at them, they were ready to continue talking.

But how could the elders of the class not know Xu Wen, as soon as they saw this young man, they instantly closed their mouths and subconsciously stood up.

At this moment, the experts looked at each other, and they were all shocked.

Lu Lihai came over a few days ago, they didn't behave like this, it could only be because of this young man.

Who is this young man? Banmen is a bunch of stubborn donkeys, does he have such prestige?

The masters of the class were purely conditioned, and after standing up, they realized that Xu Wen was mainly specialized in carpentry, and they were talking about the beamless hall here, so it stands to reason that he should not understand...... bar.

However, when they all stood up, they were embarrassed to sit down immediately, but fortunately, they asked for a good face, took the first step to salute politely, and called out their names and honorific titles one by one. The teachers were very attentive, and took the initiative to talk after returning the gift: "I heard that Master Xu has been busy with other things recently, why did he suddenly have time to come over?"

"I asked Boss Lu for help, and I heard that the masters were here recently to distinguish the authentic and authentic volumes, so I came over to say hello. My place of residence is just around here, very close. Xu Wen said with a smile, "The masters are generous, the treasure in the door like Zongzheng Juan, not only is it all selfless and public, but it is also painstakingly trying to correct it, which is really troublesome." ”

As he spoke, he saluted the experts of the Cultural Communication Society, "It's really hard for the teachers to help in their spare time. ”

He heard from Luo Yifan that the expert consultants of the Cultural Communication Society are not full-time personnel here, and they are basically leaders in all walks of life.

The Cultural Communication Society has limited funds, and they came here to help, half of it was to see his face, and more of it was because they really wanted to do something for it.

Both sides are contributing to the survival of the Cultural Communication Society, or traditional skills, and it can be said that they have the same goal, and there is really nothing to quarrel about.

The two sides had already quarreled a little angrily, but when Xu asked for a moment, they realized this matter respectively, and that anger disappeared in an instant.

"Well, there's nothing to make noise about, take a step back, and fill in the pending here. Whether it works or not, this detail can't be completed. If it can't be completed, this technology can't be realized, and it's the same whether it has existed or not. The expert surnamed Dong of the Wenchuan Association said.

He doesn't want this technology to be proven? How could it be? But after so many years, he has also seen clearly that some things are lost and they must be ruthlessly given up.

The master of the class was stunned for a moment, and didn't say anything, just sighed deeply.

"Alas, it's a pity. To be able to achieve this kind of engineering quality without having to do anything, this technology is really extraordinary. If it can be restored, it can be used for some special projects or traditional engineering repairs. Another expert from the Cultural and Communication Society shook his head and sighed, ready to put down this part and continue the work later.

"These details...... It may not be impossible to complete. As they spoke, Xu Wen picked up the part of the Zongzheng scroll and looked at it carefully.

Then, after a moment's silence, he said slowly.
