Daming: If I find a great-grandson, I will teach an emperor through the ages

Chapter 210 Teaching? Cao Wei really vomited

After staying one night in the tent outside Xu's mansion, Cao Wei returned to Cao's mansion the next day.

All we have to do now is wait for May 20th to arrive.

Except for Zhu Xiongying's death, Cao Wei is still developing aircraft.

After various calculation stages, it was time to enter the actual production of the actual aircraft model, and Cao Wei had to go back and forth between the manufacturing bureau and Cao's mansion every day again.

In addition to aircraft manufacturing, oil refining also needs to be put on the agenda, but this matter is also urgent.

Crude oil is a complex mixture whose main components are hydrocarbons, including alkanes, olefins, aromatic hydrocarbons, etc.

The principle of refining gasoline from petroleum is based on the differences in the boiling points of these hydrocarbons at different temperatures to extract different substances.

The process of refining gasoline generally includes the following steps. First, distillation. First, the crude oil must be heated and then enter the distillation vessel. In the distillation vessel, the crude oil will boil at different temperatures, and components with different boiling points will enter into different components as they boil. Layers of distillation vessels.

This is followed by fractional distillation. In the distillation vessel, multiple different layers will be separated. The temperature gradually increases from the bottom to the top. Different layers are collected into different containers to form different products.

The gasoline layer is located in the middle of the distillation vessel. The temperature is moderate and suitable for the formation of gasoline. The compounds in this layer are mainly alkanes and alkenes with lower carbon numbers.

Because these molecules are smaller, lighter, and capable of boiling at lower temperatures, these low-boiling components are collected in the gasoline layer.

After fractionation, the gasoline liquid is obtained, which still needs to be refined. The collected gasoline layer needs to go through a series of processing steps again to improve its quality and performance.

These steps include operations such as desulfurization, denitrification, and deasphalting to remove impurities and improve the combustion characteristics of gasoline.

In general, the principle of refining gasoline is to use the difference in boiling points of different components at different temperatures to separate hydrocarbon compounds with moderate boiling points through distillation. The gasoline layer is the main source of gasoline.

It sounds simple, but just making a distillation vessel that can be layered is not an easy task, nor is it easy to control the various boiling points.

It would be difficult for Cao Wei to complete oil refining alone. He needed helpers.

So Cao Wei sorted out some of the physics and mathematics he used when calculating data for aircraft models, added some basic knowledge points of chemistry, and compiled several books.

When he came to the manufacturing bureau, he asked Song Ping to find a group of people who had read books, intending to teach them these calculation methods for future generations.

At first, Cao Wei wanted Zhu Xiongying to directly find a few people who were proficient in calculations for him in the court, but after thinking about it later, it was not appropriate.

At this time, it was the early Ming Dynasty, and there had not yet appeared people such as Wang Wensu, Zhu Zaiyu, and Xu Guangqi who had a profound influence on Chinese mathematics. Most of the people in the court who were proficient in mathematics were serving in the Six Ministries, with the Ministry of Households and the Ministry of War being the most numerous.

The staff of the Household Department are busy all day long with clerical work. They basically only do written calculations. They know nothing about craftsmanship. When you come to them, you also need to consider the coordination between these people and the craftsmen. After all, The two types of people do completely different things. Similar to Party A and Party B, the supply and demand relationship cannot completely match.

Rather than going to such trouble, Cao Wei thought it would be easier to find a group of people in the manufacturing bureau to teach basic mathematics, physics, and chemistry.

Today's Manufacturing Bureau is no longer the small workshop it was when it was first established, but a large-scale scientific research factory directly under the imperial court, related to the top technology of the Ming Dynasty's manufacturing industry.

As long as the manufacturing bureau continues to develop in the future, it will one day break through the boundary and require the blessing of these new types of knowledge. Then Cao Wei will teach the craftsmen of the future manufacturing bureau the techniques they will need at this time, which is a long-term solution.

In this way, the craftsmen of the manufacturing bureau are both Party A and Party B. They know their own needs and only need to find ways to meet the needs and complete the tasks.

Moreover, the craftsmen have basic manufacturing skills and know what to do to achieve the optimal solution, so they can avoid many detours when making calculations.

It can be said that the current manufacturing bureau is becoming more and more like a scientific research institute with a manufacturing factory attached.

It's just that most craftsmen now only have practical experience and lack relevant theoretical knowledge. If they supplement this theoretical knowledge, they will get twice the result with half the effort in doing anything.

After a while, Song Ping and Zhao Heng came with more than thirty people.

There are now tens of thousands of craftsmen in the entire manufacturing bureau. Song Ping is taller among the short ones, and he finally picked out these thirty people. They are considered to be relatively well-educated at the moment. They have studied a lot, and they are all Due to various reasons, I eventually became a craftsman.

Cao Wei counted the heads. Apart from the two managers, Song Ping and Zhao Heng, there were thirty-seven people, no more and no less.

He pointed to the booklet he had sorted out on the table.

"Everyone must copy this booklet once, and then hand it over to me for inspection."

In this manufacturing bureau, no one would question what Cao Wei said. A group of people immediately found pens and paper, gathered in a circle, and began to copy the contents of the booklet.

When they were copying, they felt that they knew almost all the words in the book, but they couldn't recognize them when they were put together. They could only recognize some basic calculation methods, but as for the rest, they just couldn't recognize them. Like a heavenly book.

Cao Wei originally thought that it would take at most an hour to copy this book, but he did not expect that these craftsmen took nearly three hours.

This is because the craftsmen can't understand the contents of the book at all. For things they don't understand, they can only copy them one by one, and the progress will naturally be much slower.

"Sir, the copy is ready."

When the craftsmen handed in their papers one after another, candles had already been lit.

Cao Wei could only give up and let them go back first, while he stayed to check the thirty-nine copies and correct the errors.

The reason why it is so time-consuming and laborious to let the craftsmen copy it in person instead of directly printing it with templates is because Cao Wei thinks that letting the craftsmen copy it by hand will strengthen their memory, and then he can teach them, at least they will have a little bit of it in their minds. The impression will not be completely blind.

After doing all this, Cao Wei also returned to Cao Mansion to rest. The next day, he called again the thirty-nine people headed by Song Ping and Zhao Heng yesterday.

Then, Cao Wei returned to them the book they copied yesterday and started teaching.

What Cao Wei wants to teach, whether it is mathematics, physics, or chemistry, is some basic knowledge.

For example, in mathematics, the basic points are base notation, fractions and percentages, reductions, general divisions, divisors and multiples, various basic operation theorems, and calculation methods for the areas of various figures...

Because these thirty people had all read some books, it was easier for Cao Wei to teach than to teach students who didn't know anything at first.

But this "easier" is also a result of comparison. In the actual teaching process, Cao Wei can be said to be one head and two heads up!

Often the most basic laws of operation, such as associative law (a×b)×c=a×(b×c) distributive law (a+b)×c=a×c+b×c division property a÷(b×c)=a÷ b÷c, Cao Wei just said it, but someone forgot it, and Cao Wei could only repeat it over and over again.

Cao Wei has a good nature, but during the teaching process, he almost broke his guard several times and cursed at a group of rough men.

Only at this moment did Cao Wei think of his mentor who had taught him books and teachings, and deeply understood their difficulties.

If I had known that I was so stupid at the beginning, I should have eaten more, learned more knowledge, traveled to the Ming Dynasty, and been able to make a little boy or something...

Until May 20th, Cao Wei still could not teach all the mathematical knowledge points, let alone physics and chemistry.

Early in the morning, Cao Wei sat up from the bed, his head feeling groggy. He couldn't help but remember that he had failed again in the manufacturing bureau last night. He stood above the podium and spit, and a group of rough guys below looked ashamed and wanted to find someone. Drill into the cracks in the ground.

Shaking his head, Cao Wei asked Xiaoyu to change clothes for him.

He originally thought that this matter would not be easy, but now it seems that this journey is a long and arduous one!

The revolution has not yet succeeded, and comrades still need to work hard, Cao Wei comforted himself in his heart.

After changing his clothes and washing his face, Cao Wei felt a little more energetic. He ate breakfast in twos and headed towards the palace.

On the way to the palace, Cao Wei saw lights and colorful decorations on both sides of the street. Along the road from the palace to Xu Mansion, there was a red carpet all the way, and the festive atmosphere filled the faces of everyone on the roadside. superior.

Today is the day after Cao Wei, the chief envoy, and the deputy envoy Dai Zhu Xiong are registered. Compared with the engagement date some time ago, it is much more grand.

Chang Shiqing and the attendant named Liu were still waiting in the palace. After Cao Wei, the leader, spoke, the team behind them marched towards the Xu Mansion in a mighty manner.

At this moment, Xu Miaojin was in the boudoir, being dressed up by the palace officials. Next to the dressing table, a five-color pheasant coat was hung on a hanger.

Xu Miaojin never thought that one day she would become the queen of the Ming Dynasty.

As the most extraordinary woman during the Hongwu period, Xu Miaojin was very different from ordinary people in terms of background and experience.

Having lived in a top wealthy family like the Xu Mansion since she was a child, Xu Miaojin was used to the intrigues of the rich and powerful. She also knew the true face of those young men and their precocious nature, so she did not want to be the canary in the cage. She had always been very cautious about marriage. Keep a respectful distance.

Originally, she planned to remain unmarried for the rest of her life, as it would be better than living a dark life after marrying into another family, but the sudden appearance of Zhu Xiongying changed her mind.

As the grandson of the emperor, Zhu Xiongying was not as frivolous and naughty as other wealthy children. He was steady, kind-hearted, and generous in character.

Zhu Yuanzhang initially connected her with Zhu Xiongying. Because Zhu Yuanzhang was the emperor, Xu Miaojin did not refuse directly and thought about making plans in the future.

However, as she spent more time with Zhu Xiongying, Xu Miaojin's resistance to the marriage became less and less.

When Zhu Xiongying was with her, what he talked about most was not romance, but the country, the country, and the development of the country. Like Zhu Yuanzhang, Zhu Xiongying was also focused on the important matters of his family and country.

Xu Miaojin slowly began to accept Zhu Xiongying, who was dedicated to the world, and wanted to contribute to him, and wanted to be by his side. Before she knew it, her life was here.

After today, she will become Zhu Xiongying’s wife and the queen of the Ming Dynasty...

Outside the Xu Mansion,

Like last time, Xu Yungong waited outside the door with his entire family until he saw the team at the end of the street, and ordered people to light firecrackers.

"Crack, crackle, crackle, crackle..."

The firecrackers continued until the carriage team stopped at the gate of Xu Mansion.

Cao Wei jumped off the carriage, cupped his hands towards Xu Yungong and said with a smile:

"Congratulations, congratulations to Duke Wei."

Xu Yungong stepped forward and took his hand, "Same joy."

Then came the ceremony of enthronement. Cao Wei and his party entered the mansion and saw Shang Guan leading Xu Miaojin out of the boudoir.

Then Xu Miaojin, led by Shangguan, stood in the center of the courtyard and knelt down facing the palace.

Cao Wei took out the book at the right time and read the text to Xu Miaojin.

"Teacher Tao in the Sixth Palace, set an example in the world, and now he is the queen of Emperor Yongwu..."

It took half an hour to read the book, until Cao Wei felt his throat was dry before he finished.

Then the envoys granted the queen the certificate and treasure ribbon, and Xu Miaojin officially became the queen of the Ming Dynasty.

Then Shang Guan came forward again and led Xu Miaojin to sit down as the queen and accept the worship of the officials present.

"Welcome to see the queen!"

Xu Miaojin, who was sitting on the main seat, felt his chest rise and fall twice, obviously a little uncomfortable, then waved his hand and said:

"No courtesy, stay on your own."

"Thank you Queen!"

After the salute, Shang Yi on the side knelt down to Xu Miaojin again and said: "The ceremony is over."

The officials applauded and congratulated Xu Yungong again. Xu Yungong blushed, laughed and asked everyone to sit down, and the banquet began.

On this day, Cao Wei was also extremely happy.

It can be said that Zhu Xiongying was brought up by him since childhood. Although Zhu Xiongying became the emperor at this time and their identities were different, after more than ten years of relationship, in Cao Wei's heart, Zhu Xiongying was no different from his own son.

How could Cao Wei be unhappy seeing his son marry a wife?

This day was the first time Cao Wei got drunk. He couldn't help but think that in the future, when Cao Lin grows up, he will marry a wife and have children like Zhu Xiongying.

At that time, he will truly act as a father and arrange the marriage for his biological son.

Just for a moment, Cao Wei remembered that he had to go to the Manufacturing Bureau to give lectures tomorrow.

"Wow..." Cao Wei turned around and spat it out.

Xu Yungong was as happy as Cao Wei. He didn't need to be persuaded by others. He had already gotten himself drunk early...

Father, your boss is worried about Miaojin, she will become the queen...

The banquet lasted until late at night, and all the officials at the banquet got under the table.

If it were someone else's wedding, even if they were happy, they wouldn't all get drunk, but the emperor's wedding was different.

Are you unhappy when the emperor becomes emperor? Dare you be unhappy? You should drink it if you are happy!

Even the civil servants who usually did not drink alcohol would hold their noses and forcefully pour wine into their mouths. Only by drinking themselves to death could they prove their sincerity and loyalty to the emperor!
