Li Shen finally got permission to leave the palace and began to prepare for leaving the palace. The first is to quickly build the palace. Only after the palace is built can he leave the palace.
So I went to Xiaohuangzhuang that afternoon, because there is a mountain near Xiaohuangzhuang that is full of clay, which is necessary for making bricks and tiles. The cement is simply limestone, clay, gypsum, coal, and iron ore.
Crush it, calcine it at high temperature, grind it into fine powder and mix it to make cement. It’s all taught in junior high school chemistry. It's just that many people have forgotten it. And simple cement only requires limestone and clay. A few more trials will lead to success.
Li Shen asked Wang Hongfu to build two earthen kilns according to the drawings drawn by Li Shen. One burns bricks and the other burns cement. We'll build again after the bricks are fired, and it's already winter.
The foundation cannot be laid either. We can only build a cave dwelling on the ground to make do, since the villagers have nothing to do in winter anyway. Give them money and they can do anything. It will be completed after the Zhengyuan Festival.
This Zhengyuan Festival was the last Zhengyuan Festival that Li Shen celebrated in the palace, but there was no one in the palace that he could miss except Concubine Wei. The same peaceful atmosphere, the same festive atmosphere.
The only drawback is that there are a few fewer people at the dinner party. Some of my brothers have gone to other places, and some of my sisters have gotten married. What makes Li Shimin sad this year is that Qin Qiong is seriously ill.
Li Shen has watched TV dramas and listened to storytelling. Qin Qiong died in the twelfth year of Zhenguan, but not yet. Li Shen guessed that the history was written incorrectly, and it should have been thirteen years. Li Shen also went to see him, and the old disease recurred. Li Shen gave him penicillin several times. The inflammation and fever subsided, but he was still not optimistic.
The output of Li Shen's penicillin has remained the same in the past two years, but it can be produced faster. At present, he can only produce enough, and it is not yet popular. Qin Qiong's main illness is due to too many injuries in the past.
I was bleeding too much. I didn't feel anything at that time when I was still fresh, but now that I'm getting older, my body is failing. Coupled with the relapse of an old disease, it would be better to have a modern blood transfusion for a few days.
There is no medical solution at this time. If the deficiency is not replenished, I can't bear anything I eat. So these days Li Shimin has a sad face, very sad. The imperial doctor has said that it will be half a year at most, and the imperial doctors are also trying their best to find a solution.
Li Shen has also been thinking of ways to search his memory for ways to identify blood types and blood transfusions. The method is now available.
The first thing to solve for blood transfusion is environmental pollution, that is, bacterial infection. Li Shen can have someone make a silkworm room and spray it with high-quality alcohol. The utensils will be chicken intestines in bamboo tubes. Then he will have the craftsmen make a few needles and then use high-temperature sterilization alcohol. Soaking this is all common sense.
But the only unresolved issue now is the blood type issue. In movies and TV shows, blood transfusions are all done by close relatives, but Li Shen's doctor friend in his previous life once told him.
Hospitals generally avoid blood transfusions for immediate family members. Later, Li Shen also searched online specifically for possible complications.
It is true that the chance of complications is as high as 20%, but Li Shen couldn't find a way to identify it and finally had to use his son. If he died, he would be responsible. Anyway, there is still half a year. Let's talk about it in the end.
After the first year of Zhengyuan, Li Shen arranged for people to mine limestone and clay. Although it is freezing and cold, mining is laborious. But Li Shen didn't ask for how much he could mine. I just want to create some income for the people in the village. Every family except those working in workshops. One person can come out. Three meals a day are included for 10 cents. The villagers also knew that Li Shen wanted them to make more money in their free time. So I work hard. The two earth kilns have been completed long ago. As soon as Zhengyuan passed, Li Shen arranged for people to start burning bricks. The kiln built is a small kiln that can burn about 25,000 bricks at a time. However, due to limited conditions at this time, it takes about ten days for a kiln to be fired. Add another day to cool. At present, fired cement can only be made from limestone, a small amount of clay and cinder. Calcining for seven days is enough. When the time comes, grind it into powder and mix it together to make cement.
Li Shen spent a day in Huangzhuang instructing them on how to sift soil and make bricks to dry. Then how to put it in. How to burn. When to fill coal. Li Shen has a lot of coal now. More than a year of mining has not been sold. After Li Shen finished arranging for the bricks to be burned, he went to arrange for the cement to be burned, smashed, calcined, ground and mixed. It was not until the evening when the city gate was about to close that I returned to the palace. Li Shen thought it was time to build a manor outside the city. There is the Pianhe River in the south of Chang'an City, and a large piece of land bought by Li Shen is there. It would not be bad to build a manor next to mountains and rivers. Just use it as a resort.
The first batch of finished products will be ready to leave the kiln in half a month. Li Shen left the palace early and went to Huangzhuang. After loading the men, he opened the kiln and took out pieces of red bricks. Li Shen picked up two bricks and knocked them hard against each other. If it's not broken, it's a success. The cement has been out for a long time. Mixing. Li Shen asked someone to make several large iron rollers in order to crush and grind the powder. It takes three or four people to push it forward, although the focus is on it. But it works great. After testing the finished cement, it basically meets Li Shen’s requirements.
Li Shen asked people to continue to bake bricks and cement, and at the same time started to build new kilns. This time Li Shen built a large kiln that could bake 50,000 bricks at a time. The cement kiln was also a large kiln. Li Shen estimated that he should be able to provide for the expenses of his palace. We will consider selling it after the palace is completed.
Li Shen also asked people to build a new road from Huangzhuang to Chang'an. The road should be widened with gravel on the top and burned cinders on the bottom and cement on top. We need three carriages that can travel side by side. There were not many manpower to build the road, so Li Shen asked Wang Hongfu to go to the surrounding villages to find people. Get it fixed as soon as possible. Fortunately it's not far away, otherwise I wouldn't know how long it would take to practice.
Li Shen arranged everything and returned to the city. He went directly to the Ministry of Industry and asked Shangshu Yan Liben. He was going to let Yan Liben plan the palace.
Now that the garden, rockery and lake are basically completed, all that's left is to build the house. He needs to ask Yan Liben to draw the drawings, build the blue brick house, and the location of the kang chimney.
Originally, Li Shen wanted to build a boiler room and geothermal heating. Isn't that what the novel said, but in reality it was not allowed.
The first thing you have to do is solve the pipe problem. Copper pipes have the best conductivity and are not prone to rust. But in this era, copper is money. Even if Li Shen had the money, he would not be able to cover all the courtyards of the palace with copper pipes.
What's more, there is the problem of the circulation system. There is no circulation pump in this era. If it relies on heat conduction, it will never be hot. Even he can't make radiators in rural areas now. Therefore, Li Shen can only be used in a few places.
Li Shen discussed with Yan Liben for more than two hours, determined Li Shen's requirements, and started planning.
He didn't believe Li Shen's statement that cement could bond bricks and be as hard as stone after drying. However, Li Shen asked him to go to Huangzhuang tomorrow to see the experiment and find out. Yan Liben also needed to go back and verify whether reinforced concrete pillars were made. Draw drawings for Li Shen.
Another point is that Li Shen's purpose in finding Yan Liben is because Yan Liben knows what size of palace a prince should build, how the house should be built and decorated so as not to exceed the etiquette system. Don't finish building the house by then and be impeached for the crime of overstepping.
It's such an injustice that the house has to be demolished and rebuilt, and Li Shen's palace also has an underground part. The cellar for storing vegetables and grain, and the ice cellar for storing ice are all underground.
There is also the treasury that Li Shen requested. It is a very large treasury. Because it has blue bricks, reinforced concrete, and Li Shen is not worried about it collapsing, so he built a large treasury, just like an underground air-raid shelter. The biggest headache for him was that the copper coins took up too much space. So we can only build a big treasury.
