Zhao Shu was a bit lazy after returning from the Northern Expedition, and always wanted to take a good rest.

It's just that others can rest, but the emperor can't, so with this opportunity today, he is ready to go out for a lap.

The sun is just right outside!

He went back to change clothes, and the Zaifu returned to Zhengzhengtang to change clothes.

"That ... Xiren." Zeng Gongliang changed his shirt and turned around to show, "How?"

Like men and women, no matter how old they are, they like others to like it.

Bao Zheng glanced at him, "Tummy is too stiff."

Zeng Gongliang patted his belly and sighed: "This year old, if you are not fat elsewhere, you will have a fat stomach, but why."

Han Qi is here. The belly is big ... not big, but a circle.

The feeling of the waist of the bucket.

"What are you waiting for?" Han Qi stared at Zeng Gongliang's belly as soon as he came in, and then laughed strangely: "I think you said that there was meat in your lower abdomen. What are the six pieces ... How many are now? "

Zeng Gongliang raised his head and smiled bitterly: "It's already mixed into one."

Han Qi laughed, "No, no, no, it's ninety-nine. Hahaha!"

A group of Zaifu laughed very joyously, just when Zhao Shu came, and when they asked why they laughed, they also had some troubles.

"I have also been a little sinker in recent years, and later I ate less, but it is useless."

He really wanted to go back to the time when he was light, and he didn't eat anything fat.

"Your Majesty does not need to worry." Han Qi said confidently: "You look as strong as a minister."

Zhao Shu looked at his "burly" figure, his mouth twitched, and said in disbelief: "Yes! Han Qing is strong and strong."

Han Qi proudly said: "Chen can't ride a horse, then the chariot is not a boast, when the chariot drove to kill the Liao Army, he won the mystery of the integration of people and vehicles ...

Han Qi stood out all the way until he reached Wuxue Lane.

They came along Yujie all the way to the intersection with Wuxue Lane, just to the right of Wuxue.

The martial arts shouted the killing sound all day long, but everyone was uninterested in listening to it, but looked at the road in front of him.

The gray avenue.

"what is this?"

Zeng Gongliang was a little curious, and even stretched his foot to step on it a few times.

"It's hard!"

He stepped on again.

Han Qi's response was more direct, and he stomped up.

"Ouch!"

Han Qi's body is self-important. How much force you give to a hard object will give back how much force you give back.

Han Qi moved his sore ankle and looked around. "It's all stone laying?"

Zhao Shu also tried it and couldn't help but be surprised.

He regretted it a bit, and felt that the Imperial City Division should be kept informed of the process of road repair.

There was no one on the street, and there was a wooden shelf in the middle, with notices on the wooden shelf.

"No trampling, otherwise money will be lost."

Zhao Shu laughed: "Han Qing and Zeng Qing are in violation of regulations."

Han Qi said: "It's all stone, and his ankles are sore, why don't they leave?"

"Shen An is here."

Shen An came from the left, followed by a group of students.

"Have seen the official house."

When everyone salutes, Zhao Shu can't wait to ask: "Why are these stone paving roads so smooth? I can't find a gap, how is this done?"

"Stone?" Shen An shook his head. "Guanjia, this is not stone, but cement."

"Cement? What is cement?" Zhao Shu puzzled.

"Cement ..." Shen An felt troublesome to explain: "Cement is to grind something into a powder, then calcinate it, and finally lay it by stirring."

"That's it?" Zhao Shu felt fooled.

"Yes!"

"What kind of material?" Zhao Shu stepped on it a few times and thought it was really good.

"It's just some stones ... and slag, the mountainous **** in Izumo Temple ..."

Shen An said it was natural, but Zhao Shu frowned, "That's all?"

Some stones and **** can actually produce a stone-like effect?

Zhao Shu shook his head slightly, "Zhu Qing comes to try."

Everyone stepped up and felt very stable in the first step.

"Well, this road is hard."

Han Qi studied Yizhou dialect and pressed the road with a heavy body.

"It's very hard."

Zhao Shu felt increasingly wrong.

"Wait this way ... may be crushed by the cart?"

This question is what everyone wants to ask.

Zeng Gongliang laughed: "Just use some stones and **** to pave the road, how long can it be used?"

Whenever something new comes out, questions always follow.

Shen An felt a bit lonely, no, he was alone in seeking defeat.

This is cement, something you can see wherever you go.

Whether it is a house or a pavement, cement can be called the most determined friend of mankind. As long as you are in the city, you can see this friend when you open your eyes.

But in the Song Dynasty, Cement was the first time to show his head, like a shy girl, has not yet unveiled her veil, revealing his peerless face.

Shen An said while walking: "The Luchen first made people shovel out the original mud, then laid a layer of gravel, and then crushed ..."

After listening to his introduction, Zhao Shu felt that there was nothing new about it.

"I remember dirt roads have to be pressed?"

"Yes, Your Majesty's Expo Group Books, Qiang Wen Bo Ji, Chen Admire." Han Qi even shot his **** today, people can't help but look at it. Times crushed. "

"The dirt road can only be like this. Remember the capital city of the former Tang Dynasty. When it rains, the street becomes a quagmire.

"But Shen Annong's this one is obviously very good." The first Song of Song Dynasty, Baoqi Zheng, was on the line. "You see, the house is so solid, it can be called seamless, and I think it is the best road."

Bao Zheng vowed to go south and north, except for those stone roads, and has never seen such a real road again. He looked at Shen An with pity and whispered: "A lot of money spent? Hey!"

He felt that Shen An had smashed the road with money.

"It took a lot, but it was okay." Shen An still looks like a local tyrant.

This is not a highway, no racks are needed, the only extra cost is broken stones and cement.

Broken stones need to be beaten, this is no way. I remember that earlier in the year, there was this business all over the country, which was to recruit some workers, each of whom issued a hammer to break stones.

It was capable at that time, and it was no problem at this time.

"Don't make a noise afterwards." Bao Zheng's older, the more boundless his heart becomes, "When the time comes, let the officials give money."

Bao Zheng glanced at Zhao Shu, "You said that this road is the first cement road in Beijing, and you dare not specialize in ..."

Shen An got it.

This is the world of Lao Zhao's family. For the first time, he has to let Lao Zhao's family come.

Then the cement road is naturally too.

At that time, use this as an excuse to cheat money.

Bao Gong really is hidden!

But Shen An refused.

"Not bad!"

"It's just that the human body is light. What if the cart is crushed? Will it vibrate?"

"It's hard to say, I'm afraid the car will directly crush this road."

This insight is good. In the future, heavy truck rolling is indeed a fatal injury to concrete roads, but now ...

Where is the heavy car?

Where are the overloaded vehicles with dozens of tons in future generations?

At present, the so-called heavy truck can be one ton, which is great. Such heavy trucks can crush the dirt road into deep ruts, but it is only a joke on the cement road.

Below is the crushed stone foundation, on which is laid a concrete road, a ton of cars ...

Ha ha!

That's a joke!

Shen An laughed: "Or ... try?"

A thousand words are better than a show, a mule or a horse, let's pull it out.

Zhao Shu nodded, "I also want to see."

Shen An had been prepared for a long time and commanded: "Let Anxiang's team come."

On the right came the sound of swinging the whip, and then the team came.

"What are these big cars?" Han Qi stretched his hand on Zeng Gongliang's shoulder, and Lao Zeng almost stumbled.

"It's all alcohol. One jar is two hundred pounds. With eight jars installed, plus the weight of the cart, it's less than 1,700 pounds."

Everyone was staring at the big team coming.

"Will it be crushed?" Zeng Gongliang mumbled.

Shen An smiled and beckoned over there.

"Hurry up!"

The leading carriage accelerated.

A group of heavy cars are accelerating, that feeling ...

Shen An had seen more in previous life, so he didn't feel much, but Zhao Shu and others were like Tu Lao Hats, so they kept staring.

The heavy car rolled over, and the ground ... didn't feel any vibration.

Is this wrong?

Han Qi squeezed his eyes and hit Zeng Gongliang with his shoulder, wanting him to ask Shen An.

But what kind of body is he?

Just hit it like this, Zeng Gongliang seemed to be hit by a big car, and then jumped out.

Zeng Gongliang turned around and glared.

outrageous! Zhao Shu coughed dryly, and Chen Zhongheng asked, "Why is there no vibration on the road?"

Shen An said lightly: "Because it's not heavy enough."

Chen Zhongheng was almost mad at these words, "It's almost two thousand catties, not heavy enough?"

"Four or five kilograms is fine." Shen An suddenly felt that everything in front of him was very boring.

This is just ordinary concrete appearance, if the rails are made in the future ...

That guy didn't go up a few thousand pounds ~ lightnovelpub.net ~ but hundreds of thousands of pounds. Do these gentlemen think it is an artifact?

Chen Zhongheng glanced at him, his eyes seemed to say that Shen An was bragging.

"Get up!" Han Qi is the most sensitive to speed. When he saw the big cars start to accelerate, he couldn't help but get excited.

The big convoy started to accelerate, and Zeng Gongliang said in surprise: "Those horses are so easy? Officials, when the army is on the expedition, those horses that follow are eager to follow, and the slow ones make people anxious. I was sweating and blazing ... but why are these horses so relaxed? "

Zhao Shu also discovered this problem, and Han Qi first looked at Zeng Gongliang with disdain, then exulted, "Guan's house, this is because the road is smooth!"

Think about it, if Da Song's roads are all of this level and solid, the original cart can only pull 500 kg, let alone a thousand kg. Where it used to take ten days to arrive, it can be reached in five or six days, so this is calculated ... Guan's house, how much benefit is this? "

Zhao Shu murmured: "Hundreds of extra catties are loaded, and it's easy to run freehand, and it's fast. How much money can be saved if we go down like this?"

The army went out and the first was the first, but it was necessary to transport the first one. The slow speed along the way made the generals want to kill. This is not a big deal. People on this route spend a lot of time eating horse chews, which can make the third company want to commit suicide.

And all this has to do with the road.

The dirt road is uneven and there are potholes everywhere. How can you get up quickly?

The dirt road is too soft, and once a heavy vehicle is crushed it becomes a rut, which is getting slower and slower.

When the dirt road rains, it becomes a quagmire, and the cart will sink in, unable to go ...

So many problems cannot be solved in thousands of years.

But today Zhao Shu saw the solution.

His eyes flashed with splendor, and looking at the cement road was like seeing the country road.
