Li Er's expression was indifferent, but the hand that pressed on Li Yuanxing's shoulder couldn't help but exert his strength. said to Qin Qiong beside him: "Uncle Bao will test it later, and how about talking about some things?" ”

"Yes, Holy Lord!" Qin Qiong gave a salute.

The crossbow was naturally handed over to the forbidden army to take over, and Bai Erwa also retreated into the distance.

"Reward! Reward! Li Er said softly to Li Yuanxing, Li Yuanxing smiled and nodded: "The younger brother is rewarded, reward him with a room, you can choose a woman among the female slaves in Yaozhou who is willing to be a concubine with him, and he is also specially rewarded with a pound of meat every day!" ”

Li Er smiled, threw the cigarette on the ground and stepped on it with his feet, took out his pipe and lit it: "Say, you want a few titles!" ”

"I don't know, how many, how much?"

"Such a thing, how much, give as much as you want!"

Very tongue-twisting conversation, if it is changed to a foreigner's Chinese test, it will definitely be confused. Li Er and Li Yuanxing both laughed, isn't it a title, how many such craftsmen there are, they dare to give as many titles.

A Xi Jun can be praised as a seven-grade lieutenant when he buys it, and a good craftsman is not given a knighthood?

The two were about to say something more, when they suddenly heard a loud cheer from the crowd.

Today is not a celebration, so Li Er just appeared here as a viewer. There were no special invitations to foreign envoys. According to the observation of Qin Qiong's subordinates, none of the foreign envoys were bad, and they all sent people to mix with the people.

"Open!" A steward shouted, and the watermill began to intermodal, and the sackcloth containing the beast was torn off.

This is a fully deployed stone crusher, nearly five feet high. Seven zhang wide, and then there is a shed ten zhang long, which is the power transmission belt connected by the hydraulic connection, for which the unlucky pigs are the pigs.

The happy slaves in Yaozhou killed nearly 10,000 pigs before picking out the most haode parts, plus hemp and silk, and weaving these belts.

Hundreds of laborers pushed wheelbarrows up the slopes.

As soon as the machine was turned on, the steel rollers of the stone crusher spun. Ma Yuan's heart is also empty. This is just made according to the drawings of His Royal Highness King Qin, can it really crush such a stone?

Not only Ma Yuan, but also the people were worried, and the original noise disappeared. Turned into a whisper!

"It's really unproductive. What if it fails. At most, I can do it all over again! Li Yuanxing was very calm, Li Er shook his head gently when he heard this, in short, he hoped to succeed.

"Pour!" Ma Yuan shouted with all his strength.

The labor of the cart is also afraid. A wheelbarrow carries two stones, which are the size of a bucket, one bucket is ten liters, one liter of water is one kilogram, and the size of a bucket of stones is twenty kilograms.

The laborer of the first cart gritted his teeth, and the cart fell forward, and two stones fell into the stone crusher one after the other.

The sound of clicks came from the stone crusher.

Li Yuanxing chose the bar type, because he was afraid that Datang would lack power, so he chose the bar type. It is to crush the stone by relying on the liliang that resembles the bite of the teeth, and then squeeze the stone more by the iron roller.

"Pour, keep pouring!" Ma Yuan knew that once the machine started working, it was not interesting to throw just a few stones. And with the help of the force of the stones squeezing each other, the effect will be even better.

Under Ma Yuan's orders, the laborers began to line up to pour stones into the beast.

The loud clicking sound became louder and louder, and at the bottom of the outlet, half-inch-sized stones gushed out like flowing water.

Wow! The cheers of the people shook the sky.

The laborers were also very energetic, and hundreds of people lined up to pour stones into the hopper.

A carriage, more than 500 catties of gravel was quickly filled.

The top is poured quickly, and the bottom is loaded quickly.

Li Yuanxing made these gravels not for fun, but for road construction. A ten-zhang wide, the roadbed dug a foot, after laying the triple soil, began to pave these gravel, compacted, and then used cement as the road surface.

For fifteen miles, the paving of gravel on the roadbed has been prepared.

"Gorou, when will you use the cement you said?" Li Er watched from afar with the help of a telescope.

"Brother Huang, the weather is too cold, and it can't be used until the spring flowers bloom, and the cement is very brittle after being frozen. If you want to be as strong as a steel and stone plate, you need to warm up the weather, and I hope that you can complete the 200-mile roadbed in three months, and then complete the road surface in three months. However, the younger brother still wants to make this road more beautiful! ”

When Li Yuanxing spoke, Qin Qiong leaned over: "Holy Lord, Your Highness." Strangers are approaching a steel stone crusher! ”

"Let them see!" Li Yuanxing really didn't care.

Let's see, if you can learn it, even if you learn, you will learn to see what is the use of this thing on the grassland.

Li Er picked up the binoculars and watched from afar.

Li Er, the person closest to the stone crusher, had the impression that he was Gao Changguo's envoy deputy, and he seemed to be a somewhat learned person. He has a deep understanding of the history of the Tang Dynasty and the Han nationality.

It is rumored that this requires more than 100,000 catties of iron, so naturally you have to see it with your own eyes.

The Datang military has received an order to allow people to watch closely, but they must line up neatly, and everyone must not stop, and they must leave after turning around, and there are tens of thousands of people waiting to see it.

If you want to take a closer look, ten days later.

When Deputy Envoy Gao Chang approached, he pretended to be stepping on his shoes, and after getting permission, he turned around to pick up his shoes, and looked at the huge steel beast very seriously.

Supporting this behemoth is a pillar of fine iron, which is definitely the best fine iron. It's not pig iron as rumored.

And the two-foot-thick cylinder with its dense spikes on it was not iron, let alone pig iron, no matter how you looked at it. It was steel, the shiny teeth that had been ground by the stones, and the color that only steel could have.

Look at the shaft of the runner, stainless steel.

The most amazing thing is that the part that supports the shaft, he can't understand, he can't understand it at all, why the tightly clamped copper sleeve can make the shaft rotate so easily! It's simply incomprehensible.

A giant beast made of real steel, in just half an hour, pulled away hundreds of carriages from the rubble.

This is tens of thousands of pounds of gravel, and it has to be replaced by human force to smash it, and I don't know how much time it will take.

"Let's go, get out of here!" A sergeant came to drive people away, and Deputy Envoy Gao Chang quickly retreated from here.

In a few moments, several of the envoys gathered together to exchange information they had seen and heard.

"Datang uses so much steel to make some of these behemoths, just for the sake of gravel?" Questions were raised.

No one answered, because the ancients were not yet completely able to understand what the process of industrialization was.

In their eyes, it would be good to smash the gravel by manpower, and it would be good to smash it slowly for a few more months, hundreds of thousands of catties of fine iron, and high-grade steel, how many swords, shields, and armor would be made.

Someone else said: "Datang is telling us that when the sword is in storage, it will not fight abroad?" ”

Immediately, there was an opposing voice: "No, or that is, there is so much steel in Datang that we can't imagine it!" ”

It's just a stone crusher, is it worth all the fuss?

However, Li Er also didn't understand: "Goro, is it worth it for you to use hundreds of thousands of catties of steel!" ”

"Brother Huang, even you say so, it's better for your brother to settle an account for you!"

"Good!"

"It takes 50,000 people to build this road. With a stone crusher can save at least a few thousand laborers, these few people can not be counted. That's just the 50,000 people. If there is no stone crusher, how long does it take for 50,000 people to repair 200 miles, and the ten-zhang wide Lu Huang brother thinks it will take? ”

Li Er thought for a moment: "One year, even two years!" ”

"How much will these 50,000 people eat in a year? Just talk about food, not other accounts! ”

Li Yuanxing was very confident, but at this point, he didn't continue to count.

50,000 people, a day is 100,000 catties of grain, even if a catty is a penny, 100,000 catties is a hundred per day.

Then 100 days is 10,000 yuan, and the money saved is 20,000 yuan. This is just food, not wages, and other expenses.

The value of 100,000 catties of iron seems to have been exchanged.

"Brother Huang, the younger brother used 50,000 people, not only to repair this road, but also to renovate the Jinghe River by the way, open a canal in Yaozhou for 300 miles, and after the beginning of spring, you can get 380,000 acres of fertile land, whether it is medicinal materials or food, it is income, steel is just a dead thing, after the greatest value, it is a good thing!"

Li Yuanxing's explanation, Li Er was very satisfied.

In fact, Li Yuanxing is also changing Li Er's concept little by little, what is industrialization, there is no way to make the ancients understand with anything in books, only by seeing real benefits is the real change.

"Brother Huang, there is still a machine, if it is built. It is equivalent to the speed of five hundred blacksmiths forging armor leaves every day, and the quality is so good that this machine alone is dozens of armor blades a day. ”

Li Er nodded again.

In fact, Li Er understands some of the truths.

For example, the improved loom, one machine and eight blooms, naturally increased the speed several times.

And the water-powered loom is not only good at weaving, but also faster.

Cost! Li Er has slowly come to understand this word, which is the cost of making a thing.

Changing to Datang can also be understood as the things that Datang wants to do, how much return it gets, and how much it pays.

"Gorou let it go, and take care of government affairs for my brother this year. Readjust the laws of the Tang Dynasty, and tell Brother Wei if you need anything. Li Er wanted to go back in a hurry, and then look at the book of political economy.

A volume of holy decrees was stuffed into Li Yuanxing's hands.

There was no reading, and there was no incense case, it was just that Li Er took it out of his sleeve and stuffed it to Li Yuanxing.

When Li Yuanxing saw it, he couldn't cry or laugh. This is to make yourself spend money, bleeding money!

Datang Royal University, Datang Royal Primary School, and Datang Royal Women's College all have to be built by themselves!! (To be continued......)
