After Li Tai came to Youzhou Academy to have in-depth exchanges with Li Chunfeng, he rode back to his study room and wrote a letter.
One is a memorial to apply to Li Shimin for Li Chunfeng to become a fifth-rank official in Prince Yan's palace to consult and join the military.
The other one was written to Li Shimin, Empress Changsun, and Changle, telling them that he had arrived in Youzhou safely, and that he would write letters every month to report his safety.
As for the prince...his coming to Youzhou was partly related to the original rumors, and he was not allowed to show off his temper.
After he finished writing these, he gave the letter and memorial to Bai He and asked Bai He to send them to Chang'an through the post station.
And Li Tai asked Lu Anshou to come forward and start buying a large area of flat tidal flats in Youzhou. Of course, it would be better if there was a beach.
After all, Lu Anshou was also the Lu family of Fan Yang, but he moved to Chang'an this time.
But no matter what, Lu Anshou hasn't released the fifth server yet, and Fan Yang Lu is still willing to help if he comes to purchase Huantu here.
After all, no one is developing these wastelands. As for salt production, they will not choose these places because they are not suitable.
The most important method of making salt in this era was salt boiling. Even if salt was boiled on the seaside, the most important thing was to have a river connected to it.
Because the salt boiling method requires the use of fresh water to prepare a specific brine, and the water flow can stably transport supplies, such as firewood or coal, which are needed for salt boiling.
Even if there are large areas of tidal flats, if there are no nearby rivers to transport materials, these places are basically regarded as having no value.
It is actually not a difficult task for Lu Anshou to come forward and buy and sell some wasteland far away from the river.
Although the aristocratic families in Youzhou City felt that Li Tai, the King of Yan, was a bit stupid, and even more like someone who had been taken advantage of.
But since Li Tai wants to take advantage of him, let Li Tai do it. It has nothing to do with him anyway.
At the same time, Li Tai began to organize the aliens who came with him.
With some students who came from Chang'an as the foundation, and the foreigners who were responsible for transporting supplies as the wings, they were arranged to establish villages near the wasteland, and they had a place to stay in Youzhou.
Because Youzhou is different from Gaoling.
Gaoling was the center of the empire, so Li Tai's Gaoling did not build a city wall during the period of rapid development.
Because even if it were built, it would be meaningless in Li Tai's opinion.
After all, I'm afraid there won't be any wars in Gaoling for the next few hundred years. It's a waste of manpower to build a wall.
But it's different here in Youzhou. After all, dragons and snakes are mixed here. There are Han people and foreigners. Maybe there is a tribe that comes to rob when there is no food in winter.
Therefore, if you want to settle here, you must take precautions as soon as possible.
Otherwise, it is very likely that "you produce grain, others produce guns, and others come to snatch your harvest." That would be really stupid.
At the same time, these New Tang Dynasty people who could already speak Chinese, practice Chinese etiquette, and had quite good organizational skills after working hard, under the command of Li Tai, began to build villages and build walls in these deserted places. When all these were completed, they were completed.
, and let the excavation road begin to connect with the main road in Youzhou.
These people can follow Li Tai only because Li Tai treated them well when they were renovating Zheng Guo Canal. In addition, Youzhou is closer to their hometown. The most important thing is that they have no assets in Chang'an. This is why they came.
premise.
It seems that Li Tai also takes good care of the people of Gaoling, but the reality is that it is impossible for the people with local assets in Gaoling to throw away their assets and follow Li Tai to Youzhou to start over.
And if Li Tai returns to Chang'an in the future, will they abandon their assets in Youzhou and follow Li Tai?
This is inherently unrealistic.
Therefore, compared to the people of Gaoling, it was these duckweed-like aliens who followed them to Youzhou.
Because to them, it really doesn't matter where they go.
Even if Li Tai proposed the difference between miscellaneous books and good books, they didn't know much about it.
After all, they themselves know that they are from a different race and are inferior to others wherever they go. Is there any difference between a miscellaneous family and a good family?
Now, under the command of Li Tai, they are building villages and erecting walls near Sanhui Haikou and near the tidal flats.
Sanhui Haikou can be understood as the intersection of the South Canal and the North Canal. Near the Sancha River mouth of today's Jingang Bridge, although there are scattered people gathering here, strictly speaking, there is no village here, let alone a name in the historical sense.
This is one of the origins of Tianjin, but the earliest historical name of Tianjin, Zhigu Village, had to wait until the Jin Dynasty.
So now the group of people brought here by Li Tai have established a village here. If it really develops into Tianjin, it can be regarded as the origin of Tianjin.
It has to be said that after they established a village and were assigned their own houses, their eyes began to light up.
At least based on past experience, as long as Li Tai continues to direct their work, their lives will get better and better.
No matter what, at least they still have such hope in their hearts.
But what puzzled them was that originally they were given food stamps for work, but now Li Tai directly gave them food stamps.
Although the physical food is difficult to get, it is more practical to hold the food.
The enthusiasm for building houses and walls is also a bit higher. After all, there is so much rice in the rice vat at home, so how can one not be prepared for safety.
In the following days, Li Tai mainly managed these New Tang people, built villages, built wooden walls, and repaired roads, which was in full swing.
At first, Li Tai rewarded them with various daily necessities in the form of rewards.
After various supporting personnel were dispatched in an orderly manner by Peacock, they came to Youzhou to find Li Tai.
Then, this newborn village soon had medical buildings, restaurants, brothels, clothing stores, bathrooms and other buildings located there. A small but well-equipped planned small village of 5,000 people appeared on the tidal flat near Jinkou.
.
Of course, this town now only has a population of about 2,500, even including the various technical personnel who arrived later.
But after Li Tai sent people to build the first layer of the wall, he immediately sent people to start building the second layer of the wall.
If the area surrounded by the second layer of walls is full of people, the population of this small village can even reach 20,000 people. However, even the first layer of people has not yet been filled up. Now the construction of the second layer has started, but it has left thousands of people.
It makes people feel a little confused.
Li Chunfeng took care of the chores of the Youzhou branch, completed the handover of the mountain director of the Youzhou branch, and came to Li Tai.
The appearance of this city made Li Chunfeng feel that Gaoling was full of life when he saw it.
"King Yan." Li Chunfeng saluted quickly when he saw Li Tai, and Li Tai also showed some joy when he saw Li Chunfeng.
Li Taidao, "Chunfeng, you are finally here. If you don't come, I will go to Youzhou Academy to catch you!"
"Thank you to King Yan for your concern. Now that I have handed over the affairs of Youzhou Academy, I am willing to work for King Yan!" Li Chunfeng said.
"This matter really can't be done without you!" Li Tai said to Li Chunfeng, "But you still remember what I said about salt and profit!"
"Chunfeng remembers!" Li Chunfeng couldn't help but nodded after hearing Li Tai's words, indicating that he understood the matter.
"Well!" Li Tai said, "So, Chunfeng, you need to do this, and only you can do it!"
"Please give me your instructions, King Yan!" Li Chunfeng heard Li Tai's words and saluted Li Tai respectfully.
"Bai He, please take notes next to me!" Li Tai said to Bai He before he told Li Chunfeng.
Bai He nodded when he heard Li Tai's words, and immediately began to study his ink and pick up his pen, and began to prepare shorthand.
And Li Tai said, "This method is called the sun-salt method, and its principle comes from the evaporation combined with the law of the sun and the law of water!"
Faced with these exotic words spoken by Li Tai, Li Chunfeng accepted them very calmly.
After all, Li Tai's method of enlightenment was really implemented in schools, and certain generally accepted theorems are called laws.
In fact, Sun Simiao's investment in gunpowder research was said to be studying the law of fire. Even if Li Chunfeng had studied wind, he was formulating his own law of wind.
Therefore, what is most studied in agricultural schools is the law of the sun, the law of water, which studies water sources, and the law of wood, which studies crops.
The study of evaporation is naturally related to the sun and water.
Although it is just a simple observation phenomenon, for Li Tai, this simple observation phenomenon can already be used in real objects.
This whole process can be regarded as observing phenomena to form theoretical rules, and then applying these theoretical rules into practice.
Therefore, Li Tai asked Bai He to record this paragraph and submit it to Li Shimin for later viewing.
What is the law of the sun and what is the law of water? These are not meant for Li Tai and Li Chunfeng, but for Li Shimin thousands of miles away.
"Compared to the time and effort we use to burn coal as energy, if we use the tidal force of the law of water to affect tens of millions of seawater, and use the law of the sun to transpire seawater, then making table salt will be twice the result with half the effort!"
“As for the sun-salted method, in my imagination, I use this as the principle, and then further dismantle and realize it.
There are a total of five steps of whole beach, collecting tide, making brine, crystallizing, and raking salt to make a sufficient amount of coarse salt!"
"Please tell me more, King Yan!" Li Chunfeng sat upright and listened carefully to Li Tai's words.
"The first step is to renovate the beach. The first step is to build a canal around the seaside. At the same time, the land on the seaside continues to be rested.
Make each salt field with a wide area and distinct layers. From the outermost to the innermost, the area of each salt field should be smaller than the last.
We determine how much area the first salt field will be based on the last salt field, and you need to calculate this!"
Li Tai looked at Li Chunfeng. This was the most important reason why he came to Li Chunfeng.
In the subject of mathematics, at least in this era, there are really too few people who want to surpass Li Chunfeng, and now most of the things I need to do require mathematics, otherwise I can only rely on experience to explore bit by bit, instead of
Let's rely on science to count.
“When the whole beach is completed and salt pans are built, and there are channels to control the waves, we can use the high and low tides of nature to open the gates of the channels, release seawater into the salt pans, and use the law of the sun to expose the seawater and make the seawater transpire.
Let the salt stay!”
“The next step is to make brine.
Seawater has different compositions and contains many impurities. These salt fields are designed to increase the concentration of brine and facilitate crystallization.
At the same time, it is also to use various methods to remove seawater impurities through precipitation, so that the salt content in the brine becomes more and more pure.
As the brine continues to gather into the next salt field, the water becomes less and less and the concentration becomes higher and higher, so the area of the salt field becomes smaller and smaller.
The biggest fear during this process is that it will rain, so the salt fields need to be exposed to the sun, but they can also be protected from rain when needed.
The simplest thing is to build supports around it and use canvas to cover it when the rain comes.
Of course, I believe you can definitely come up with a better way, just slowly explore it in practice."
"After the brine production is completed, crystallization begins. It is best to put a rope in the crystallization tank and have people stir it in circles for a long time.
Otherwise, the salt crystals may not crystallize uniformly, but will solidify piece by piece, making it inconvenient to collect and transport!”
"The last step is to rake the salt. Use a salt rake to collect the coarse salt in the crystallization tank, and then you can get coarse salt."
"It's absolutely shocking!" Li Chunfeng listened to Li Tai's words and said,
"This has never happened before, but it is logical to reason from the laws of the sun and the laws of water.
Chunfeng took the order and planned the salt field for drying salt according to the requirements of King Yan."
At this time, Li Chunfeng was quite excited, even a bit pure when he was searching for the path.
To be honest, building the so-called salt farm and obtaining the so-called first pot of gold are really not the most important thing to Li Chunfeng.
At this time, what Li Chunfeng really cared about was that the theory of proof that Li Tai proposed originally was more of an internal discussion method, but now he can really apply the principles of proof in practice.
This opened Li Chunfeng's eyes. At least compared to the so-called construction of salt farms and opening up ways to make money, at least this shortcut method of attaining enlightenment seemed to be a real path.
A path that does not rely on talking and arguing, but uses observation and mathematics to prove the laws of the Great Way, and then apply these laws in reality.
If salt is really produced in this way, not to mention the method of boiling salt, even if it is only one-third of the method of boiling salt, it can be proved that the method of enlightenment, shortcut, and then enlightenment proposed by Li Tai is a real and feasible pursuit.
Avenue way.
For a time, Li Chunfeng was full of energy. Compared with Li Tai, who only wanted to get the first pot of gold in Youzhou, Li Chunfeng's eyes were shining. The sudden burst of belief seemed to give Li Chunfeng a layer of haziness.
Unrequited brilliance.
To Li Tai, Li Chunfeng's whole person was as if after swiping the computer interface that was stuck on the screen, his whole person became energetic, even a bit indescribably hot, like a burning torch!
"What's wrong with Chunfeng? Did I say something to make him excited?" Li Tai looked at Li Chunfeng in confusion, but said calmly, "Since you understand everything, I'll leave this matter to you.
Tell me what you need, and I will definitely help you!"
"No!" Li Chunfeng replied sonorously and forcefully.
