Now this concrete, although the strength is OK, used to lay the floor or something, the problem is not very big, but it still has a problem. ”

Li Kuan couldn't help but feel a little proud when he saw Yan Liben's surprised expression.

No matter how good you Yan Liben is, you have to admit defeat in the face of knowledge that transcends time and space.

"What's the problem?"

"Because it's made of gravel, sand, water and cement, the slab is strong enough, but if it's made very long, like a beam, then the toughness will be insufficient."

"Lack of resilience?"

Yan Wenwen didn't understand this meaning a little.

"To put it simply, it's like this slate, you just used a lot of effort to break it. But if this stone slab becomes slender, then a hammer will definitely break, which is a lack of toughness. ”

As soon as Li Kuan explained this, Yan Wenwen immediately understood.

"Lord, if these are the two, then the beams in the hall still need to be made of wood?"

"yes, let's use wood for now. However, the wood doesn't have to be very large. ”

"What about the pillars?" Yan Wenwen asked a little worriedly, "These pillars also need to be built very high, if the toughness is not enough......"

"The words of the pillar, this king thought of a solution."

"How?"

"Filling iron bars and hemp bamboo in the middle, because the pillars are thick enough, it is not easy to have problems in itself, and adding iron bars and hemp bamboo in the middle, I think there is no problem. If you're worried, try making one first and see how it works. ”

Hearing Li Kuan say this, Yan Liben finally breathed a sigh of relief.

The pillars of the main hall are the most difficult to manage, not to mention the giant trees that are needed, and it is even more difficult to transport.

"Okay, lord, then I understand, the design of this new palace, I will also go back and revise it again."

……

Li Shimin is in a very good mood these days.

The state capitals of the Tang Dynasty were in good weather, there were no droughts and floods, and the construction of the new palace was supported by the courtiers.

Even the Emperor Taishang, who has always ignored himself, said a few more words to himself after he went to ask for peace and said about the construction of the new palace.

"Li Zhong, how is the construction of the new palace?"

Li Shimin asked while reviewing the recital.

"Your Majesty, it's only been ten days, and there hasn't been any movement."

"Huh? No movement? What do you mean? It's been more than ten days, and you said that there is no movement at all in the construction of the new palace? ”

Li Shimin couldn't read it anymore, his eyes were fixed on Li Zhong, and he motioned for him to explain things clearly.

"His Royal Highness the King of Chu has been busy in various workshops during this time, and he has not been to the new palace for the time being, and he has not received any instructions from the general supervisor for the time being, and the situation of the household department is similar."

Whatever Li Shimin cares about, Li Zhong has to focus on investigating something, and it is obvious that the construction of the new palace is the thing that Li Shimin has been most concerned about recently.

Li Zhong was really careless, and grasped the movements of Li Kuan, Yan Liben and others at any time.

However, there really hasn't been much movement.

I can only report truthfully.

"Bang!" Li Shimin slapped on the table, "This Li Kuan, what kind of fame." Could it be that he still wants to deceive the king? ”

"Your Majesty, the prince's work has always been expected by everyone, but in the past two years, it has never disappointed, and I think it should be my own plan."

"What do you mean by having your own plan? It's been more than ten days, and he hasn't even been to Xingong. He didn't even know where the new palace was built, how did you make me believe that he had his own plans? ”

Li Zhong was sprayed by Li Shimin and was a little suspicious of life.

I'm Li Zhong, I'm not Li Kuan.

Fortunately, at this time, Lan He hurriedly ran in from outside, which can be regarded as rescuing Li Zhong.

"Your Majesty, the Xuanwu Gate guards will report urgently!"

"What?"

Li Shimin's face changed dramatically!

The three words of Xuanwumen are too sensitive.

The Xuanwu Gate is too important for the Taiji Palace.

It is not without reason why several coups in the entire Tang Dynasty took place in Xuanwumen.

Taiji Palace is located in the north of Chang'an City, and Xuanwu Gate is the north gate of Taiji Palace.

It can be said that out of Xuanwu Gate, out of Chang'an City.

In other words, attacking Xuanwu Gate is much simpler than attacking Chengtianmen and Yonganmen.

Because of this, near the Xuanwu Gate, Li Shimin was handed over to the Seventh Battalion of the Northern Ya, which he trusted the most.

Now, Lan He suddenly ran over and said that Xuanwu Gate was in a hurry?

Could it be that the crown prince had a coup d'état?

Impossible, Li Shimin knows Li Chengqian very well, and with his current appearance, he can't command a few generals at all.

What's going on?

Li Shimin did not have an answer for a while.

"Your Majesty, a large number of people have gathered a few miles outside the Xuanwu Gate, and it is said that there are more than 10,000 people, so the guards urgently sent people over to warn."

Seeing that Li Shimin's face changed, Lan He hurriedly explained the situation.

Call!

Hearing that there was nothing to do in Xuanwu Gate for the time being, Li Shimin breathed a sigh of relief.

However, there are a large number of people gathering within a few miles, and this situation should also be taken seriously.

Although the Seventh Battalion of the Beiya is extremely elite, the number of people is only a few thousand, so it should not be careless.

"Let's go, I'll see for myself!"

The Xuanwu Gate emergency report just now was received not only by Li Shimin, but also by all the court bigwigs who worked in Menxia Province and Zhongshu Province.

No one needs to emphasize it, everyone knows that this matter must be taken seriously, and they have personally gone to Xuanwumen to find out.

The Xuanwu Gate is based on the high slope of Longshouyuan, and the city gate is built very high, and the view is very good.

Standing on the city gate, you can not only see the panoramic view of Taiji Palace, but also the vast area to the north of Chang'an City.

"Your Majesty, that's it, and now there are more and more crowds."

Li Shimin stood on the city tower, surrounded by heavily armored hundred cavalry guards, Fang Xuanling, eldest grandson Wuji, Wei Zheng, Wen Yanbo and others also boarded the city gate one after another and stood beside Li Shimin.

"Did you send a scout out out to make sure?"

No one needs to tell himself, Li Shimin can see at a glance a few miles northeast, a large number of people have gathered, and there seems to be more and more trends.

No wonder the Xuanwu Gate guard will come to warn, it's really not normal.

"Your Majesty, I have already sent three groups of scouts out of the city, and I think there will be results soon. Weichen has also asked all the soldiers of the Seventh Battalion of the Northern Ya to wear armor and swords, and they should be ready for any situation that may arise. ”

Li Shimin stood there, frowning, and did not speak.

"Report!"

Soon, a scout galloped back on horseback, but the Xuanwu Gate guard did not let people open the gate, but threw a hanging basket from under the city tower and let the scout come up from the hanging basket.

It's an extraordinary moment, and you can't be too careful.

Li Shimin looked at it and nodded secretly in his heart.

The Seventh Battalion of the Northern Ya still lived up to my trust.

"Your Majesty, the situation has been clarified, there is no danger for the time being, those people are all ordinary people and craftsmen from all over the world, and they said that they want to join the workshop of the Chu Palace."

"What?"

If Li Kuan was in front of him, Li Shimin felt that he might not be able to help but kick him off the city tower!
