Zhu Yijun banged on the table, thinking quietly, Li Zhen's thinking was very radical, and Zhu Yijun also wanted to promote it, but Zhu Yijun knew that now was not a good time. However, it is still possible to promote it among civil servants.

No matter what kind of reform, political reform is fundamental, the current official team of the Ming Dynasty, two words: hehe!

However, it is still possible to shape a doctrine and standard for civil servants.

Touching his chin, Zhu Yijun felt that although Li Zhen's theory could not be promoted for the time being, it could be considered by both industry and commerce. This helps to collect your own business taxes, and by the way, it also diverts your attention.

Li Zhen saw that Zhu Yijun was silent for a long time, and his expression was also very serious, he was a little worried.

Glancing at Li Zhen, Zhu Yijun said with a smile: "Yes, I will tell Lu Shenxing that you will teach and write at the same time in the future!" Saying that, Zhu Yijun smiled and picked up the sweet potato on the stove: "It's baked!" ”

A touch of loss flashed in Li Zhen's eyes, and he said so excitedly just now that he didn't mean to act.

In fact, Li Zhen knew that the emperor asked him to come to the capital, and he definitely did not let him teach and write, and he also intended to take advantage of this opportunity. Think about Dong Zhongshu and think about the predecessors of Confucianism, this is a great opportunity for me to leave my name in history.

Through Zhu Yijun's attitude, Li Zhen also knew that the emperor was interested in his doctrine, but he couldn't give much support.

It's already a good thing to let yourself lecture and write here, and the rest is left to your own. However, Li Zhen is confident that he has been in the Civil Service Academy these days, and he knows what is lacking here.

Although the civil service academy will also talk about some things, and it is very demagogic, Li Zhen knows that it is not the right way.

The lack of an idea in the Civil Service Academy, an idea that allows civil servants to identify with themselves, is why Li Zhen teaches here. In fact, to achieve this goal, Li Zhen can be regarded as having completed the goal.

It is impossible to reach the sky in one step, which Li Zhen knows very well.

Glancing at the happy young man who was eating roasted sweet potatoes, Li Zhen showed a smile on his face, the future is long!

After eating a roasted sweet potato and drinking a large bowl of warm tea in the civil service school, Zhu Yijun left here in a good mood. This 100-member civil servant training has been completed, and they will come in handy at the end of the year.

By the beginning of next spring, there will be another recruitment of civil servants, but more than 100 people will be recruited.

After getting into the carriage, Zhu Yijun instructed Zhang Whale: "Go to the Armed Forces Division!" ”

In fact, Zhu Yijun hasn't paid attention to the Armament Division for a long time, but from time to time there are excerpts from the household department, and most of them complain about the Armament Division's money. If it weren't for the fact that the official gentry got a lot of money by paying the grain in one piece, it is estimated that Zhang Xueyan, the head of the household department, would have to find his own theory.

But Zhu Yijun doesn't care about this, some money is worth it, so it has to be spent.

It's time for the Armament Division to come up with something, and this time Zhu Yijun went to the Armament Division to see something new.

When Zhu Yijun came to the Armed Forces Division, Pan Jitao and Chen Ju were already waiting here. The two of them obviously dressed up, so as not to lose their manners in front of the king. Zhu Yijun doesn't care about these things, he cares more about things.

"Two lovers, excuse me!" Glancing at the two of them, Zhu Yijun said with a light smile.

Chen Ju can no longer see the white fat in the palace, the whole person is a lot darker and stronger, but Pan Jitao on the side is still the same. This waiter of the Ministry of Works, who was afraid to enter Beijing at the beginning, has long been working with peace of mind.

The two of them all stood up, respectfully followed behind Zhu Yijun, and walked out towards the Armament Division.

"You burned things out?" Zhu Yijun glanced at the two of them and asked.

Pan Ji didn't steal the limelight, and let Chen Ju say that he was a eunuch after all, and when he went to the Military Reserve Division with him, he was much less close to the emperor. This kind of opportunity to perform, Pan Jitao felt that it was more appropriate to give it to him.

"Back to the emperor, the firing of red bricks is effortless, and there is not much difference between burning green bricks, and it was fired after a few experiments!"

Zhu Yijun nodded, the red bricks were fired by him, the hardness of the green bricks and the red bricks is about the same, but the cooling method is different after firing, and the red bricks are naturally cooled, which is simpler, so the production of red bricks is more, and the green bricks are water cooling (in fact, it is a kind of anoxic cooling), which is more troublesome to operate, so the production is relatively small.

Although the strength and hardness are similar, the performance of green bricks in anti-oxidation, hydration, atmospheric erosion and other aspects is significantly better than that of red bricks.

The productivity of this era is already low, and the output of green bricks is so low, although many places of red bricks are not as good as green bricks, but the production is simple, which is enough to kill green bricks in seconds, with cement, twice the result with half the effort.

At this time, Pan Jitao on the side took over Chen Ju's words, and he knew that Chen Ju was not suitable to say the following words.

"Your Majesty, this red brick minister also tried it, although the hardness is enough, but compared to the green brick, it is still much worse!" Pan Jitao reminded on the side, this must be said in front, don't have problems at that time.

Zhu Yijun glanced at Pan Jitao and said with a smile: "I know! ”

"How's the cement firing?"

"Back to Your Majesty, it was also successful!" Pan Jitao hurriedly spoke.

There are several large wooden barrels on the ground not far away, the outside of the barrel is tightly clamped with iron sheets, and the inside is covered with oiled paper, and the cement that Zhu Yijun wants is contained in the barrel, walking over, reaching out and pinching a little, Zhu Yijun nodded with satisfaction.

"Good stuff!"

Zhu Yijun sighed, although I don't know what grade this cement can reach, but as long as it can be made, this is good. Glancing at Pan Jitao, Zhu Yijun said with a smile: "Did you let people try?" ”

"Back to Your Majesty, I've tried!" Pan Jitao nodded, pointed to a wall not far away, and said.

"The red brick cement has laid the foundation, but it has only been a few days, and it has not dried, and the weather is cold, so the effect is not good." Pan Jitao once again gave Zhu Yijun a preventive injection, for fear that Zhu Yijun would not be satisfied.

Glancing at Pan Jitao, Zhu Yijun shook his head helplessly, Lao Pan is the root of the ups and downs of officialdom!

The construction with cement at this time is simply a joke, of course Zhu Yijun knows what the consequences are, just a simple test of the effect. Glancing at the wall in front of him, Zhu Yijun nodded.

Leaving cement and bricks, Zhu Yijun began to pay attention to today's focus, that is, steel!

"You gave me a fold, saying that you made the crucible steel, but don't let me down!" Zhu Yijun looked at the two people and spoke.

Anyone who pays attention to modern history knows that crucible steel is definitely a key point that cannot be bypassed, that is, the method of melting metal in graphite clay crucibles to become molten steel, which is the first method of producing liquid steel in human history.

I really don't know about this Zhu Yijun, but I mentioned it to Chen Ju once.

In the past ten years, Chen Ju has been researching, collecting craftsmen from all over the world, and Zhu Yijun found several foreigners after he walked in. It should look like a Portuguese or something, anyway, Zhu Yijun is face blind.

There are also a few Indians, this Zhu Yijun knows each other, and he will not admit his mistake.

"Tell me about it!" Zhu Yijun looked at the busy scene in front of him and said to Chen Ju.

Chen Ju nodded, and hurriedly said: "The craftsmen cut the carburized iron into small pieces and put them in a closed clay crucible, heated them outside the crucible, and the iron continued to absorb the carbon in the graphite and melted into high-carbon molten steel, which was cast into small ingots and forged into the desired shape. ”

After saying this, Chen Ju said with some hesitation: "It's just that although this method can obtain crucible steel, the output is extremely small and the cost is very high. ”

"But Your Majesty, don't worry, the slave maid will let people hurry up and develop it."

Zhu Yijun glanced at Chen Ju, this is not so easy, you must know that it was the arc steelmaking method that replaced the crucible steelmaking side later, that thing had to use electricity to build a thermal power plant, Zhu Yijun felt that he could only think about it.

Not enough, Zhu Yijun didn't hit Chen Ju, but patted him on the shoulder with a smile and said, "Just do your best!" ”

Reaching out and picking up a steel ingot of crucible steel, it was a little cold, but Zhu Yijun still couldn't help but look at it.

Crucible steel may have many disadvantages, such as low output, high cost, and cannot be mass-produced, but it has an advantage that Zhu Yijun urgently needs.

When the steel is melted in the crucible, graphite carbon can also play the role of a reducing agent, the oxygen in the steel can be removed, and various inclusions can also be removed from the liquid steel, so the quality of steel is better than that of various metal materials now, which can be used to manufacture tools for processing metal materials.

Crucible steel, also known as tool steel, is irreplaceable.

Of course, it is also the best for forging swords, Zhu Yijun has also seen some information before, it is said that Damascus steel is this kind of crucible steel, and Zhu Yijun doesn't know if it's really fake, just took a casual look.

Crucible steel is definitely the best metal in the world right now.

With crucible steel, it is possible to make a lot of tools for cutting and engraving metal, and it is the best tool steel. With this kind of steel, it is possible to get some drill bits out, and with drill bits, it means that another thing that Zhu Yijun wants will appear, that is, rifling.

With rifling, you can make rifles, that is, rifled guns, and rifling will solve the problem of aiming firearms.

Even if it is expensive to build and low in production, the rifle has a great effect, such as the rifleman. Ambushed in the brigade, shooting accurately, like a sniper in later generations, of course, it is still far from this step, and Zhu Yijun can only work in this direction.

With the crucible steel, Zhu Yijun felt that the Wubei Division should be able to make a lot of good things, and he had confidence in the craftsmen of the Ming Dynasty.

"Give me a sword!" Zhu Yijun threw down the crucible steel in his hand and said, "Except for this one, you are not allowed to beat others, all the steel must be used, you know?" ”

"Wait for you to understand!" Pan Jitao and Chen Ju hurriedly bowed and said.
