In the middle of the night, everything that should be said was finished, and the lights in Zhao Dezhao's room went out.

Pei Gean was driven by him to the next room to rest, and he slept soundly alone.

Before dawn, Zhao Dezhao got up again, and under Yuan Burang's arrangement, he had a battle with more than 20 forbidden soldiers in the field without weapons.

This kind of fighting is similar to frolic, but it is much more serious, and the slightest mistake will provoke Yuan Burang to scold.

Of course, he wouldn't scold Zhao Dezhao, but he mobilized everyone's emotions, and the effect was the same.

Fighting with the forbidden army, Zhao Dezhao was beaten less, but he would also be disgraced by the forbidden army.

Now the ground is not completely dry, and everyone is covered in mud.

After the morning exercise, the forbidden soldiers all stripped off their clothes and jumped into the West Lake to take a bath.

Of course, Zhao Dezhao would not go with them, so he returned to the pond in the backyard and washed it up.

After breakfast, Zhao Dezhao didn't ask anyone to wait in the name of sightseeing, and took Pei Ge'an and the fourth sister out for a walk.

The forbidden army only followed from a distance, so as long as no one harassed them.

The east bank of West Lake is flat, with only a few hills.

Zhao Dezhao made an inspection and chose a place where he could build a kiln with Pei Ge'an.

This kiln had to be built, because the refractory bricks had to be fired first, and with the refractory bricks, a small steel-making crucible could be built.

As for the open-hearth furnace and blast furnace for steelmaking, there is no way to build it yet.

Don't underestimate refractory bricks, under today's conditions, it is not easy to make suitable refractory bricks.

From ancient times to the present, the refractory bricks needed for steelmaking are plastic, refractory clay, and hard kaolin-like skeleton clinker after calcination.

And these soil materials are not much around Kaifeng Mansion, and they must be transported from Xinzheng.

As for crystalline natural graphite materials, or high-temperature resistant synthetic materials in later generations, such as silicon carbide, alumina corundum and ferrosilicon and other crucible materials, it is even more unrealizable.

Only when refractory bricks are made and crucibles are smelted can there be containers that can make steel.

Since the Qin Dynasty, there have been large-scale iron-making furnaces among the people, but it was not until two thousand years later that the problem of furnace temperature for steelmaking was solved.

In ancient times, the highest furnace temperature was only 1,200 degrees, and even 7800 degrees was the norm, while the melting point of iron was more than 1,500 degrees.

When the furnace temperature is not enough, the iron cannot melt the molten iron, but only turns red and soft, and then relies on manual beating to remove impurities.

This method also leads to too many impurities in the iron, and the iron is not pure, and it is even more time-consuming and labor-intensive to get steel on this basis.

A small block of steel can take a blacksmith several days of toil.

Zhao Dezhao originally did not understand the steelmaking process, but in the Ming Dynasty, he experienced the steelmaking era from open hearth, blast furnace to converter, and even if he did not understand the details, he knew the main procedures.

In modern times, she built two steel mills in South America, and she has specialized in the history and technical details of the development of steelmaking in the world.

Not only does she know how to make steel, but she even knows the technical skills of Indian Uzi steel.

This technique of relying on pig iron and wrought iron at different temperatures to absorb the charcoal in the iron and then form a patterned crucible steel was the first time he had heard of it.

Originally, he thought that all the Uzi steel was forged and beaten.

After selecting the site, Zhao Dezhao left Pei Ge'an and several younger siblings behind, and returned to the city with half of the guards to attend Shi Baoji's birthday.

There are no younger brothers and sisters, and a group of guards are the same as Zhao Dezhao, all of them are on horseback, and it only takes half an hour to return to the city.

Now, although the Great Song Dynasty lacks horses, there will be no shortage of Zhao Dezhao, the prince, and his hundred guards are all cavalry.

Coupled with the horses pulling the cart, the East Palace has a quota of one hundred and twenty horses, and if one dies, it will be made up immediately.

There is nothing to say about this birthday party, it is nothing more than eating and drinking at noon, and then a group of people will fight again in the afternoon.

Regardless of whether they lost the fight or won the battle, they had a new bickering, and then they continued to get drunk at night before they went home.

Zhao Dezhao had to go back to the farm at night, and he didn't get drunk, but after he came back, he was seduced by a little goblin who couldn't touch him and couldn't sleep all night.

This daughter-in-law knows very well where Zhao Dezhao's bottom line is, anyway, even if Zhao Dezhao can suppress her, she will be made to death.

After spending three days at the farm, Zhao Dezhao built a refractory brick kiln based on his experience in the Ming Dynasty.

However, before the kiln was tested, the palace sent someone to deliver the decree.

After Wang Pu handed over the chapter, Zhao Kuangyin approved him to teach Zhao Dezhao history in the future.

Not only does he want to go back, but several younger brothers and sisters also have to take it back, and now in the palace, Zhao Kuangyin is really alone, and he also misses his children.

When Zhao Dezhao returned to the East Palace, he found that Zhao Kuangyin, who was a father, seemed to want to attract a few children by relying on the amusement park, so he moved all the toys to Gyeongbokgung Palace.

At this time, several younger brothers and sisters had no excuse to stay in the East Palace.

Only Pei Ge'an did not come back with Zhao Dezhao, she had to supervise the hoop kiln first, and after the kiln was built, she had to test the fire.

Only by firing refractory bricks that can withstand high temperatures of 1,400 degrees can we continue the next plan.

A kiln that burns bricks and does not attract the attention of others.

Moreover, Liu Xiao stayed in the farm to cover for Pei Ge'an, and no one would notice her existence.

On June 20, Wang Pu and five other teachers came to the East Palace at seven o'clock in the morning.

Every morning, there will be an hour and a half of studying, starting from noon, there is no need to study, it is Zhao Dezhao's social time.

On the first day of class, Wang Pu did not start the class at the beginning, but gave Zhao Dezhao a study plan, which was actually similar to the curriculum schedule of later generations.

The emperors of the early Song Dynasty did not need to study scriptures and Confucianism, but they needed to learn not only history, but also astronomical astrology, feng shui divination, sacrificial regulations, diplomatic strategies, and management guidelines......

How to manage an elite team with both civil and military officials, how to manage a country-scale ancient company, and how to deal with the relationship with surrounding tribes and countries...... There are so many things to learn from the ancient Chinese princes!

Therefore, although Wang Pu is the leader to teach Zhao Dezhao to learn history, a large team of think tanks is still needed to teach him.

Finding that there was no one for him, Zhao Dezhao secretly breathed a sigh of relief.

Xu Shi was Zhao Dezhao's former Mongolian teacher, responsible for Zhao Dezhao's literacy, as well as the foundation of scriptures.

He is too familiar with Zhao Dezhao, and Zhao Dezhao's handwriting has changed greatly now, so he can't hide it.

Without him, it would save Zhao Dezhao the effort to explain.

Since it is a formal study, of course, it is in the side hall of the main hall, not the side hall of the apse.

Although it is a partial hall here, the area is huge, and when you open the front and rear doors and windows, it is quite cool inside.

Zhao Dezhao sat on the Luohan bed at the top, with a big desk in front of him, and several teachers gave him a set of test papers to test the basic level.

In this kind of private teaching, the teacher must know the level of the student at the beginning, and then teach the student according to his aptitude.

A lot of this knowledge is easy for Zhao Dezhao, but he can't show it.

It's like astronomy and geography, no one taught him before, and he can't just come up and give a lesson to Qin Tianjian's teacher.

So even if he knows more than this teacher, he must hide it.

There are also sacrificial rituals, which no one has taught him systematically before, so even if he knows that the sacrificial rituals of the early Song Dynasty cannot be compared with the Ming Dynasty, he can't come out and say to the people in the Ministry of Rites that I know more than you.

However, in terms of history, he still showed some talent appropriately, and Wang Pu could not be treated as a blank slate.

For the education of social elites in the past generations, history books are compulsory subjects.

Why do social elites from ancient times to the present day read history books every day like ascetics? Especially the emperor, you can not learn anything else, history must be learned.

I thought that there was nothing new under the sun, and that history was the sum total of the experience of all our ancestors.

There is an endless library of cases in the history books, which can cultivate a person's insight, be able to see through the essence of things, see the entanglement of human nature, see the laws of the economy, and make the right decisions in a complex and changing world.

Ancient people had limited access to information, let alone the concept of a global village, and what happened in a country would not be known even after decades.

Summing up lessons and lessons through history is the most trouble-free method.

Therefore, the prince studies history, not only to remember the time, place, and people.

Instead, it is necessary to analyze the essence from one thing in order to pass the test.

The real bull pays attention to and learns from history the methods and courage of historical figures to make decisions in the turbulent and unpredictable situation, and learns how to gain insight into the world and formulate rules.

In ancient emperor education, history was the most important, and princes who had not gone through this stage of education did not even know how to be a good emperor.

Although the scriptures developed from the Tang and Song dynasties became a hotbed for the development of Confucianism, they did have a certain positive role in increasing the emperor's knowledge.

Of course, in the later period, I didn't talk about history, but only about the scriptures, which was completely biased.

Except for Wang Pu, the crown prince and Taibao, although the other teachers have low official positions, they are all elites selected by various yamen, at least in what they are good at, they have a certain authority.

And when they saw Zhao Dezhao's words, they were immediately shocked.

Holding Zhao Dezhao's words, one by one he was reluctant to put it down.

"Rixin, when did you practice this handwriting?"

Zhao Dezhao smiled slightly: "I used to have messy handwriting, but recently I opened my mind and invented this ugly book." ”

Zhao Dezhao's characters were very famous in the Ming Dynasty, but most people could accept them, because the new Song Dynasty style and thin gold body at that time had been on the market for hundreds of years.

His font is somewhat similar to Song Huizong, without his regularity, but with his own style, he was humbled by Zhao Dezhao as an ugly book.

But in this era of the early Song Dynasty, he became a generation of self-created fonts.

For a while, everyone even forgot to take the exam and instead appreciated Zhao Dezhao's words.

(It took two days to sort out my thoughts, and I will resume normal updates in the early hours of tomorrow morning,)
