Take the warehouse back to the end of the Ming Dynasty

Moreover, he himself established many factories in Xuan Town, which solved the livelihood problems of many people.

The military fields that the military households occupied by the officers were also returned to the military households by Zhao Wen.

Encouraging production and persuading farming and mulberry classes is what a town general should do.

Today, there are too few commanders like Zhao Wen in the entire Ming Dynasty.

"My lord, there is one thing I can't understand, and I hope you can explain it to me."

Song Yingxing looked at Zhao Wen and said solemnly.

Zhao Wen chuckled and said slowly, "What's the matter? Tell me and I'll listen."

Song Yingxing nodded, and said slowly: "It's not an important question, I'm just curious, where did your lord find out about this steam engine?

A steam engine was made before, and not long after this steam engine was made, a more sophisticated and powerful steam engine was made.

I really don't understand how my lord can produce this more sophisticated steam engine in such a short period of time? "

You must know that the improvement of a thing does not mean that it can be improved just by improving it. Among other things, it is just the technology of ironmaking, which has been developed and summed up after hundreds of years of evolution.

As for Zhao Wen, the things he created seemed to appear out of thin air, and had never appeared in history.

And it can be successful without any experiments, which is simply impossible for Song Yingxing.

Song Yingxing looked at Zhao Wen, and suddenly remembered the rumor in Xuanzhen Town.

Could it be that Zhao Wen is really not a human being, but a god in the sky?But this is too nonsense, right?

Song Yingxing, who believed in the study of real objects, really couldn't believe this rumor.

Zhao Wen looked at Song Yingxing with a dignified face, smiled slightly, and said slowly: "I can't explain your problem to you. Anyway, what I can produce must be useful and effective."

Song Yingxing saw that Zhao Wen didn't want to talk deeply, so he nodded, "Since your lord doesn't want to talk, I don't want to ask."

"Let's not talk about this first, what is Mr. Song doing here?" Zhao Wen looked at Song Yingxing and asked slowly.

Song Yingxing took out the booklet from his sleeve and handed it to Zhao Wen, "I made a special trip to record these ironmaking blast furnaces.

My lord, the molten steel is directly smelted in this iron-making blast furnace, so I just want to see what is the reason.

I have been wandering around this iron-making blast furnace for the past few days. I seem to have heard that this iron-making blast furnace was also improved by adults? "

Song Yingxing pointed to the iron-making blast furnace behind, his face full of admiration.

Zhao Wen waved his hands, and said calmly, "I also made the iron-making blast furnace, but I just improved it a little bit, it's not worth mentioning, it's not worth mentioning."

Zhao Wen flipped through a few pages of Song Yingxing's brochure casually, and then returned the brochure to Song Yingxing.

"Mr. Song, would you like to go to the steam engine workshop with me?"

"No, I just came out of it. By the way, Mr. Sun is still inside."

Song Yingxing waved his hand at Zhao Wen, then narrowed his eyes, and looked solemnly at these blast furnaces.

Seeing Song Yingxing like this, Zhao Wen couldn't help chuckling, and then walked towards the steam engine workshop.

Just as Zhao Wen entered the steam engine workshop, he saw a dozen people gathered around a table.

Among them, Sun Yuanhua is in the center. He looked at a part on the table, and said solemnly: "Have you still not figured out how to prevent air leakage? The surface of this piston is still too rough, and it can't reach it at all." Sealing effect."

Sun Yuanhua pointed to a miniature piston on the table, his face full of seriousness.

"My lord, we really can't process it, and this level is already the best we can process it.

The pistons in the previous steam engines were processed in this way, but there was nothing wrong with it. "

A shirtless black-faced man looked at Sun Yuanhua and explained in a deep voice.

Sun Yuanhua said: "The previous steam engine had only one cylinder and only one piston, and the boiler was so big, the pressure of water vapor was high, and the impact of rough pistons was not too great.

But now there are several steam engine cylinders. If the pistons are not smooth enough, the efficiency of these parallel cylinders will be greatly reduced. "

"But we have tried many methods, but it still doesn't work."

"Yes, yes, we have used many methods, but it still doesn't work. The pistons are all made of steel, and they are very hard. It may not be so easy to polish the surface of the pistons smooth. "

Zhao Wen stood aside, looked at the scene, and nodded involuntarily.

Now the scene that Zhao Wen saw was exactly what he wanted to see. In the process of manufacturing, what he was afraid of was not the problem, but the fact that he did not dare to solve the problem when he encountered it.

Zhao Wen walked slowly behind these people, looked at the miniature piston on the table, and suddenly asked, "Mr. Sun is thinking about the piston leak?"

Hearing Zhao Wen's voice, Sun Yuanhua hurriedly stood up and looked at Zhao Wen, "My lord, why are you here?"

Zhao Wen laughed and said, "Let me see how the manufacturing process of your steam engine is going. Has the problem of air leakage not been resolved yet?"

"My lord, the piston is not in close contact with the cylinder, and the problem of air leakage has not been resolved." Sun Yuanhua shook his head and said helplessly.

"I want to know what methods you have used to prevent air leakage, and I want to know what your plan is."

Zhao Wen walked to the table and looked at the piston on the table.

The piston on the table looks relatively flat from a distance, but if you look closely, you will find that there are many very small potholes on it.

Although these potholes can't be seen unless you look carefully, in the cylinder, water vapor will leak out of these potholes.

"We applied wax to the piston, but unfortunately it didn't work. We also polished the piston carefully, but no matter how we polished it, we still couldn't polish the surface of the piston to a smooth and airtight level." Sun Yuanhua pointed to the miniature version of the piston on the table , said with a melancholy face.

This problem has tormented Sun Yuanhua for a long time.

Sun Yuanhua thought of many ways, but it still didn't work.

Listening to Sun Yuanhua's voice, Zhao Wen stroked the piston with his hand.

"Then you haven't thought about changing to another material? Since steel doesn't work, then change to another material, such as copper."

"Copper? Use copper to make pistons? I never thought about this. Can copper really make pistons?"

Sun Yuanhua was taken aback for a moment, and looked at Zhao Wen with a confused face.

"Why can't copper be used as a piston? If you don't try it, why don't you know that copper is not good? When you cast the piston, you can cast the piston a little smaller, and then leave a groove on the piston.

With this groove in place, you can cast the brass into a brass ring the size of the inner wall of the cylinder, and figure out how to snap it into the groove on the cylinder.

One brass ring is definitely not enough, you'd better get two or three.Copper is easier to polish than steel, and copper is softer and more malleable.

In this way, won't the air leakage problem be well solved?The copper ring is in direct contact with the inside of the cylinder, and the steel piston only acts as a tool to carry the copper ring.

In this way, the contact area between the piston and the inner wall of the cylinder will be much smaller, which reduces the friction between the piston and the cylinder. "Zhao Wen looked at everyone's puzzled expressions and explained slowly.

The steam engine was invented in the late eighteenth century, but vulcanized rubber was invented in the middle of the nineteenth century.

Obviously, the two were not in the same time period at all.

Before the advent of vulcanized rubber, which could act as a seal for a steam engine piston, countless people worked on piston seals.

After their research, it was found that after the piston is covered with copper, the sealing performance will be greatly increased.

Not only in the era of steam engines, but also in the later generations of industrialization, there are not a few people who use copper as sealing rings.

In fact, this method was also thought of by Zhao Wen just now. There were many things before, and Zhao Wen mainly didn't put his mind on it, so he didn't think of it for a while.

Now that the marriage is over, the Yulin book of the land of Gyeonggi has been obtained, and everything is almost done, so Zhao Wen puts his mind on the steam engine.

"But is this really okay?" Sun Yuanhua still couldn't believe that the problem that had troubled him for so long could be solved with just a few copper rings.

Zhao Wen smiled slightly, and said slowly: "Why doesn't this work? How do you know it won't work if you don't try it? Well, you first make a cylinder as I said, and you can try it first. If this method works, then the future The pistons of steam engines are all made in this way."

"Since this is the case, let's experiment first. If this method is really possible, then we will make pistons according to this method in the future."

Sun Yuanhua patted the table, and hurriedly asked someone to fetch a piece of rice paper, on which he redrawn the manufacturing diagram of the piston.

Zhao Wen looked at Sun Yuanhua who was drawing seriously, and walked outside with a smile on his face.

Zhao Wen wandered around the ironworks for a long time, and then returned to the General Military Mansion accompanied by guards.

As soon as he returned to the General Military Mansion, Zhang Helang, who was in charge of the treasury, walked into Zhao Wen's study with a depressed expression on his face.

"My lord, something has happened." Zhang Helang looked at Zhao Wen and said worriedly.

Seeing this posture, Zhao Wen hurriedly asked, "What happened?"

"My lord, one of our loans has not been recovered. It has been overdue for two months now, and there is still movement." Zhang Helang said.

"How much money? Who was the loan given to? Do you know the details of the lender?" Zhao Wen asked quickly.

Zhang Helang took out a folded piece of paper from his pocket and handed it to Zhao Wen. "My lord, it's all on this piece of paper."

Zhao Wen took the paper over and looked at it carefully.

After a while, Zhao Wen slapped the piece of paper on the table, and said with a gloomy face, "Hehe, how dare you borrow money from me and not return it to me."

"My lord, I feel that they did this on purpose." Zhang Helang looked at Zhao Wen and said in a deep voice.

Zhao Wen snorted coldly, and said slowly: "It's not obvious. It's just a domestic slave of the British government, but he dared to borrow money from me and refuse to return it. I don't believe a domestic slave would have such courage."

Zhao Wen walked out of the study, looking at the sun in the sky, his face was full of gloom.

"My lord, what should we do now?" Zhang Helang asked slowly, following behind Zhao Wen.

Zhao Wen sneered, and said, "What should I do? What else can I do, of course, get all the money back. This British Duke, hehe, is really courageous."

"Okay, stop talking nonsense, go and get Zhao Daniu for me." Zhao Wen's eyes flickered coldly.

If this matter is not resolved properly, the blow to the bank will not be so great.

Zhang Helang cupped his hands at Zhao Wengong, and then walked outside.

A moment later, Zhao Daniu stood in front of Zhao Wen.

Zhao Wen looked at Zhao Daniu, and said slowly: "Gather a thousand guardsmen and follow me to the capital."

Upon hearing this, Zhao Daniu's face shone brightly, "Who is your lord going to the capital to deal with?"

"British Duke." Zhao Wen said coldly.

"Obey." Zhao Daniu clasped his fist at Zhao Wen, and then walked outside.

At this time, the personal guard battalion was training in the school grounds, so the speed of assembly was quite fast.

Zhao Wen returned to the hall and put on his armor under the service of Hai Lanzhu and Li Xiaoying.

"Where are you going to fight again? Every day, besides fighting or fighting, I really don't understand what's going on with you men." Hai Lanzhu looked at Zhao Wen and said dissatisfied.

"It's normal for men to make meritorious deeds. Not only can we not control them, but we must give them the greatest support." Li Xiaoying took Zhao Wen's helmet and said slowly.

"You, you know that Brother Zhao agrees with you, really." Hai Lanzhu rolled her eyes at Li Xiaoying and said with a resentful expression.

Zhao Wen looked at the two people who were bickering and said, "Don't worry, this time it's just a trivial matter, it can't be called a war, so don't worry."

Zhao Wen waved his hands at the two, and then walked outside.

When Zhao Wen came to the school grounds, more than 1000 soldiers had assembled, and each of these soldiers had a horse beside them. These horses were all horses that Zhao Wen got from the Horqin Department, and they looked very handsome.

Standing on the high platform of the school grounds, Zhao Wen looked at the group of soldiers in bright armor and armed with live ammunition, and shouted angrily, "Someone owes me money, and this person is from the British government. What do you think should I do?"

"If you don't pay back the money you owe to your lord, no matter who it is, it's a crime worthy of death,"

"Sin deserves death, sin deserves death, sin deserves death."

The soldiers waved their weapons and shouted angrily.

The soldiers who can be selected to enter Zhao Wen's personal guard camp are absolutely loyal to Zhao Wen.

This group of people doesn't care who their opponents are, as long as Zhao Wen orders them, even if there are mountains of swords and flames ahead, these people will rush over without frowning.

Zhao Wen looked at the menacing soldiers, pulled out the waist knife from his waist, pointed at the sky obliquely, and shouted loudly: "Target the British government in the capital, kill."

"Kill kill kill!"

The soldier roared three times, and then immediately got on his horse.

Zhao Wen jumped down from the high platform, got on his horse, pointed in the direction of the capital, and roared angrily, "Let's go!"

As soon as Zhao Wen finished speaking, the more than 1000 people marched in the direction of the capital.

At the same time, in a restaurant in the capital, several richly dressed sons were sitting in a luxuriously decorated room.

"Brother Zhang, how much money did you get from Xuanzhen?" Zhu Xiaomin, the son of Cheng Guogong Zhu Chunchen, looked at the British prince Zhang Shize with bright eyes.
