Li You's Tang Dynasty

Chapter 102 Cement also needs to be produced
"Keep talking!" Zhang Jing looked at Zhao Fang, the captain of the third team, and said.

"Of order!" Zhao Fang bowed, but soon Zhao Fang said something troublesome, and then he heard Zhao Fang say: "Now not only Yan Hongxin has been found, but Princess Gaoyang has also been found. The mastermind who devoured the food!"

"Princess Gaoyang...!" Zhang Jing showed a slight frown.

"Hiss!" Slightly took a breath and said, "How could there be her? The family in this house is not the best at counting. Why did they do such a thing this time. It's unreasonable."

Then I saw Zhang Jing waving his hand: "This matter must continue to be investigated, first of all, control all the grain merchants, secondly, let me watch that Yan Hongxin, and check to see if there is anyone behind Yan Hongxin , if there is... is it Yin Hongzhi or Yanxian Concubine."

"Follow orders!"

Afterwards, the fourth and fifth teams of unscrupulous people also talked about their investigations in turn, but none of them attracted Zhang Jing's attention, and Zhang Jing paid the most attention to the food embezzlement case of the third team.

If Princess Gao Yang was not involved, then Zhang Jing would go to the palace overnight to report back.

But this involved Princess Gao Yang and the Fang family, so Zhang Jing would have to wait. However, anyway, this case of engulfing food was the first case Zhang Jing planned to hit bad guys.

Because this case can publicize the goodness of the Li family, it also dealt a blow to the aristocratic family, because those grain merchants are basically the shadows of various aristocrats, elevating the royal family and belittling the aristocrats.

Zhang Jing would never miss it.

In the early morning of the next day, Princess Gao Yang took action, and began to disregard the details of the grain engulfment. The reason given was that Fang Xuanling was angry, and this reason was actually acceptable.

After all, the Fang family didn't necessarily need such money, and Gao Yang's father-in-law got angry, so he had to quit.

The grain merchants even cheered themselves up, because as long as Gao Yang could withdraw, they could earn more, but Gao Yang's withdrawal this time gave a dangerous signal to another person, that person was Yan Hongxin.

Because of Gao Yang's withdrawal, Yan Hongxin felt a bad feeling, so he prepared to advance his plan.

At Dunhuafang, people got busy early in the morning. Li You divided the 300 people into several groups. The elderly and children went to collect firewood and weeds outside the city.

Then set up a grass-burning group, which is also composed of children and the elderly.

After burning, it is filtered, and after filtering, it is boiled again. Then it is boiled lard. After all the processes are divided, Li You found that less than half of the people were used, and most of them were the elderly, children and women.

The strong labor of the two of 620 is actually useless at all, mainly because making soap really does not require strong labor. Under such circumstances, Li You is going to start making another thing. With this one thing, Dunhuafang The speed at which the house is built can be brought up.

Haha someone must already know what it is.

That's right, cement!

Some forms of cement have been used since the 8th century BC.The Egyptians built the pyramids with lime mortar, and the Romans built the Colosseum and the equally famous temples and ancient stone passages with hydraulic cement.

Ancient China also began to use lime lime mortar in the 7th century BC.

During the Southern and Northern Dynasties, a building material made of glutinous rice mixed with lime mortar was invented. The strength is far greater than that of pure lime mortar, which is very strong. During the Ming and Qing Dynasties in China, the brick walls of many buildings were still made of glutinous rice and lime mortar. Stand firm.

But the cost is expensive, and no one can afford it except the government, and the rest of the people really can't afford it. Therefore, in the Tang Dynasty, houses with wooden structures were basically the mainstay.

Cement in the modern sense was invented by the British in the 18th century. After cement entered China, it was called "cement". In 1889, the first modern cement factory was founded by Chinese talents.So as long as you travel to before the Qing Dynasty, you can get gold, silver and status for yourself by inventing cement.

And making cement is easy:
Raw materials: limestone, clay, iron slag

Manufacture: Grind limestone and clay into flour, then calcinate the clinker, and then grind it into powder with the slag left after ironmaking.

Just this sentence, very simple!Among them, the principles and steps are not for the traveler to worry about learning. In ancient times, mature lime firing technology has existed for a long time, and there are no technical barriers.A lot of technology is just an inspiration, and it is worthless to put it bluntly.

Cement is very useful. The first point is cement roads: if you want to get rich, you must first build roads. This is a truth that modern people are familiar with.

In ancient times, there were many muddy roads, which were easily damaged by wind and rain. Masonry roads or roads made of eggs and glutinous rice were too expensive, so they could only be built on a small scale.

Therefore, the significance of building cement roads is sky-high, such as communications, marching, grain roads, trade, etc.In a nutshell, the territory of ancient China was limited by the scope of information radiation, which was too far away for the central government to control, and convenient transportation can strengthen the control of the frontier and increase the radiation range of the regime.

The second is to build a city: this is mainly to build a military fortress. A simple and easy-to-repair military fortress is of great significance for resisting foreigners and strengthening the border.

As soon as he said it, Li You immediately sent Xue Rengui's second brother to do the job. Xue Rengui's second brother was named Luo Jin. He was born and bred in Chang'an. It would definitely be more effective if he came to help Li You do the shopping in Chang'an.

After explaining the matter, Li You was sitting on the second floor of his own, looking at the busy figure below, at this time Xue Rengui came up and said: "Goro, I have recruited 30 people. But, I am just worried about this Will the matter attract the attention of the imperial court? If someone with a heart comes forward to you, it will be troublesome."

"Brother-in-law. There are only 30 people, don't worry. We are also protecting ourselves. Next to Dunhuafang is Qinglongfang. There are all kinds of bastards in that workshop. I feel uneasy, and Sizi is here. No one can take it lightly. Out If something happens, I think His Majesty will help me with it!"

"That's good, then I'll start training!" Xue Rengui nodded, and then went downstairs.

There is a smile on the corner of Li You's mouth. Now there are 30 people, and after these 30 people, there will be 300 people, and 3000 people will rise from the sky. Li You showed the sleeve arrow on his wrist and smiled: "I really hope that in the future You will never be needed."

"Ha ha ha ha!"

At this moment, Sizi's happy laughter came from below, and Li You looked down, and it turned out that some little guys who were about the same age as Sizi came back from collecting firewood outside and caught a little hare for Sizi.

The hare was still black, at least Li You didn't look cute at all, but Si Zi regarded it as a treasure. She told Li You that this was the first time she received a gift from a friend.

Later, Sizi gave each of the rabbit children who gave her a gift in return, which was a lollipop that was very precious to Sizi.

Li You is really lucky, his sister is so cute. In the future, he will definitely swear to protect his sister like revenge, and no one can hurt her!

　Thank you for ruining the naivety for asking for a reward, five people for a reward, and four more for sending, asking for investment, asking for collection, thank you very much!
