During this period, the Tang smelting process was actually very high, and the Tang knife would add a certain proportion of carbon to increase the toughness.

However, due to the original steel, there is still a big gap between the quality of ordinary Tang knives and the knives made of this Uzi steel, if the shipping route is stable, Sun Xiangfu will import a large number of this Uzi steel from Tianzhu, you know, this thing will be extinct in the seventeenth century.

Of course, the test knife is to chop, Li Shimin's arm strength is very strong, yes, ordinary swords can't withstand his knock, after slashing several wooden stakes in a row, Li Shimin finally remembered to collide with the steel knife, and then, Chang He's beloved saber was sad.

Due to the large gap in the toughness of the two knives, the knife in Li Shimin's hand was fast and heavy, Chang He was passively slashed, and his saber was cut into two sections without accident.

"Boy, with your skills, it is more than enough to come to my Qianniuwei as a captain in charge of ordnance, and help Ben General build a war knife like the one in His Majesty's hand, and this matter will be considered a deal."

When Marseille heard this, he looked embarrassed, waved his hand and said, "General, this can't be done, you want a war knife, why bother, you only need to send a thousand steel costs, and the grass people are willing to build one for you for free." ”

A good weapon is definitely worth a thousand gold for a general, and a sword that can easily cut off the saber in his hand is hard to find, not to mention a thousand, no matter how much money he is willing to pay.

patted Marseille's shoulder, Chang He smiled and said, "Your brother will admit it, and the material money will be delivered tomorrow, and after your weapon is built, send someone to notify the general to come and pick it up in person." ”

After that, Chang He happily chased after Li Shimin's back outside the smelting workshop.

"Your Majesty, the minister promised the position of captain, and the boy who struck iron refused without even thinking about it."

"Well, these people used by Sun Zhengming told me to rest assured, and I will send more people to and from here in the future, but if there is a new process, I want to know it as soon as possible."

"The last general commands."

The manufacture of iron and ordnance has always been strictly controlled by the imperial court, Li Shimin has always allowed Sun Xiangfu to develop these things, in fact, it is also a kind of trust in him, Li Shimin has never felt that Sun Xiangfu's loyalty is problematic, he just did not feel his awe of the monarchy and worship and superstition of the Son of Heaven in Sun Xiangfu.

He let Chang He be so tempted, because he was afraid that Sun Xiangfu would leak out these technologies and other technologies, but he didn't know that Sun Xiangfu paid more attention to the issue of secrecy than him, and those technologies that flowed out of Happy Village were basically production technologies that Sun Xiangfu deliberately flowed out to benefit the whole people, and he could manage things that would really affect the stability and security of the country.

After visiting the smelting workshop, Li Shimin came to the cement workshop and glazed workshop under Chaishan, the cement firing technology Sun Xiangfu was handed over to the imperial court early in the morning, in fact, it is not much to see, but the inventory of Xingfu Village is obviously a little too much, at least 10,000 young people in the disaster have been arranged to work here, in addition, there are 10,000 people, who have been arranged in the quarry of Zhongnan Mountain.

"Why are there so many people here?"

Li Shimin has figured out the routines of Happy Village, and if he knows that he doesn't understand, he can just ask the person with the word "agriculture" written on his clothes, so it was Zhao Xi, a native of Happy Village, who answered him.

"Your Majesty, the village chief said that if you want to get rich, you must first build roads, our village is only more than 100 miles away from Chang'an, and now there are tens of thousands of disaster victims, just enough roads can be repaired, the village has burned so much cement, and a lot of gravel has been mined, it is to build a cement road that leads directly to Chang'an."

"Straight to Chang'an?"

Cement road Li Shimin from the small river set also saw it, it is really easy to walk, especially the carriage, there is basically no resistance, will not be bumpy, the speed is much faster than taking the official road, if you pave a straight cement road to Chang'an, then from Chang'an to Xingfu Village can shorten a lot of time, especially for transporting goods, even if it is a carriage full of goods, it can be reached in less than two hours.

"Although there are many workshops in your village, they do not produce goods in large quantities and sell them to the outside world, so why spend a lot of money to build such a road?" Fang Xuanling asked puzzled.

"Well, what the village chief said is not to help our happy village get rich, our village is rich enough, he is talking about helping the people in Guanzhong get rich, building the road to Chang'an is only the first stage, and then the road to Hongnong and even Luoyang will be built······

Zhao Xi's words are endless, but the picture he described shocked Li Shimin and several ministers, how much does it cost to pave a cement road from Chang'an to Luoyang? You must know that even the current yellow mud and gravel slag official road in the Tang Dynasty is built by successive dynasties and gradually accumulated.

"How is this possible?"

After Zhao Xi's call was finished, Xiao Yu shook his head and said.

"The grass people also thought it was impossible at the time, but when the village chief assigned us the task, he said, don't underestimate the power of the people, as soon as autumn comes, there will be millions of disaster victims who have no food to eat in the land of Guanzhong, millions of people, every 10,000 people, only need to repair one mile of road every day, and the road in the land of Guanzhong will change greatly, let's reserve the materials for road repair in advance, it depends on whether the imperial court dares to organize a major overhaul and special repair······

"This ······"

Xiao Yu was dumb again, he thought that it was whimsical to build a cement road from Chang'an to Luoyang, but he didn't want to, Sun Xiangfu wanted to complete the construction of the entire road network in Guanzhong, what he didn't know was that Sun Xiangfu still remembers that he and Sun Dali pushed a wheelbarrow and took the mud road to the small river to sell fish, more than ten miles of mud road, they often have to walk for more than an hour, less than fifty miles of the county seat, they actually have no ability to walk over, at that time, it is the road that restricts their development.

However, building roads is not something that Sun Xiangfu simply said to repair, land requisition, and sending personnel, which all need to be organized and operated by the government, Sun Xiangfu has opened a new road for Li Shimin to provide disaster relief, and how to use the labor force of these disaster victims depends on his own consideration.

"Xuan Ling, let's discuss it later, if it's really feasible, I think this road can be repaired."

"The minister also thinks it is feasible, in the past, the imperial court was not advisable to feed the victims in vain, and it should take this opportunity to build the infrastructure that Sun Zhengming said, and the minister has also studied this thing before, if the streets in Chang'an City are ······"

The demand for infrastructure construction is everywhere, there are not many bluestone paved streets in Chang'an City like Zhuque Street, most places are yellow mud pavement, once it rains, the sparse places that are pressed by the ruts of horses are everywhere, the people often spend more shoes walking on such roads, the body is dirty, they need to be freshened, the goods are dirty, they affect the color, it is very inconvenient, if they are all built on the cement road, it is different.

Thinking of the millions of hungry mouths, Xiao Yu felt that the imperial court was not indispensable for building roads, but it was necessary to do it, he was not a dull brain, on the contrary, once he recognized the matter, he would implement it very resolutely, so he said, "It's not that you can do it, but how to do it, as long as the victims have a place to work and can earn rations, there will be no chaos, the minister suggested that Your Majesty should take advantage of this rebellion to make an example of the chickens and monkeys, reserve some food for the victims in advance, and use all kinds of resources, Contribute to the construction of roads. ”

"Xiao Xiang's words are reasonable, tomorrow, I will summon the officials above the household department, the Ministry of Industry, and the Ministry of War to discuss together!" Li Shimin's favorite thing is Xiao Yu's political foresight and execution, so in the Zhenguan Dynasty, Li Shimin will use Xiao Yu as the prime minister when he wants to do big things, but it is easy to offend people when he is in power with a character like him, of course, he suffered a lot of political fire for Li Shimin, so he can go to Lingyan Pavilion to rank ninth after his death.

Next to the cement cave is the glazed workshop, because there is already a telescope and dressing mirror in his hand, Li Shimin is very interested in the glazed cave, although there is still no pure transparent glass fired, but the exquisite glazed products have been burned out a lot, the price of this thing in the Chang'an market is comparable to jade, in Li Shimin's view, it is a gold weapon.

However, when he came to the cave where the glass was fired, he saw the expressions of the craftsmen when they took out the fine glass from the cave, but he was not happy, and when he asked, he realized that what they wanted was the kind of transparent glass that could make telescopes and dressing mirrors.

After discovering a lot of guards in front of and behind the cave, Li Shimin was relieved, you know, this time to encircle and suppress Li Xiaochang's Lizhou army, the second-generation telescope in Li Shimin's hands has played a lot of roles, outflanking the encirclement and annihilation battle, and the people who have an overview of the overall situation have the bonus of the telescope, they can timely remedy the deficiencies of all parties and maximize the combat power.

This time, it was precisely because of the design of a very perfect encirclement that the army of the imperial court completely annihilated Li Xiaochang's rebels at a very small cost.

As for Li Xiaochang, a person who rebelled at a time of national crisis, Li Shimin was determined to be executed, but before this execution, it was necessary to dig up some children of the family who conspired with him.

Li Shimin has a lot of prisoners like Sun Xiangfu brought back from Lingnan who can testify to the crimes of the family, they are all secretly imprisoned in the palace, and when necessary, they can be released to bite people, like this Guanzhong disaster, the court is short of food, it is a necessary time.

In fact, after watching it for so long, Li Shimin and his party did not see the core of Happy Village, those children wearing peasant clothes were the key cultivation objects of Sun Xiangfu, and Li Shimin basically did not see such children doing things during the half day he visited Happy Village.

At the foot of Shibayama, on the slope of the fishing ground in Xingfu Village, after lunch, all the children dressed in agricultural costumes gathered here.

In the fields cultivated along the slope of the river, each small piece has a wooden sign with the words "so-and-so experimental field", which adds up to only two or three acres of land, but dozens of crops are planted.

"Zhao He, your lettuce and I were sown at the same time, but now it is a big circle smaller than mine, and the trial planting failed, it is estimated that you were lazy when you drained the fertilizer, go to the warehouse to get the seeds and replant it!" Don't just use the pig manure you got from your dad this time, remember the proportions, and add some other ingredients to ferment it······"

Similar discussions were very lively on the riverside, and Li Shimin and several ministers looked at them from a distance, listening to some terms that they didn't understand at all, and wanted to combine these things with the content of "Qi Min's Technique" that they had read some time ago, but found that it was not the same thing at all.

But they didn't think that this was because the children were not learning well, after all, in front of them was a field that was very dense and free of any weeds, so the problem should be on themselves, so they looked at each other and walked over to the place where the children were.
