Take the warehouse back to the end of the Ming Dynasty

Chapter 242 Dare to borrow money and not pay it back?

Hai Lanzhu looked at Zhao Wen who ran out, with a puzzled expression on his face, "Isn't it just to eat? Is that what you are doing?"

Li Xiaoying stood beside her, looked at Hai Lanzhu, and said with a smile on her face, "Don't you try your own delicious barbecue?"

"The barbecue I made is excellent. When Abu ate my barbecue, he cried out of the deliciousness." Hai Lanzhu said, took out a piece of barbecue from the basin, and stuffed it into his mouth.

Just after eating it, Hai Lanzhu sprayed it out, "This is too unpalatable."

Hai Lanzhu wiped her mouth, and looked at the barbecue in the basin with disgust, "I understand now, why Zhao Wen doesn't eat my barbecue, it turns out it's too unpalatable."

Zhao Wen ran out of the General Army Mansion, called the guard standing at the door, and then headed towards the ironworks.

Because he was not in a hurry, Zhao Wen walked instead of riding a horse.

Zhao Wen put his hands behind his back and looked around on the road.

"Steamed buns, steamed buns, freshly baked buns."

"Steamed buns, delicious steamed buns, hot steamed buns just out of the pan."

The street is full of cries, and it looks very lively.

Zhao Wen looked at the steaming bun shop, took out a few copper coins from his pocket, and then walked towards the shop.

"Bring me two buns." Zhao Wen looked at the peddler standing next to the cage, and put the copper coins in his hand on the peddler's table.

Seeing that it was Zhao Wen, the peddler hurriedly said, "Lord Chief Soldier, I can't ask for your money. I'll take this bun from you."

The peddler first took out a few steaming buns from the drawer, wrapped them in straw paper, and handed them to Zhao Wen, then hurriedly picked up the copper coins on the table, and stuffed them to Zhao Wen.

Zhao Wen took the bun and took a bite, "You can take this copper coin if I give it to you. What are you talking about? There is no one in this world who doesn't pay for meals."

"But my lord, I really can't ask for your money. If I ask for your money, then I will be stabbed in the back. You are really kind to us, my lord. If I still want money, then But I really can’t justify it.” Holding the copper coins, the peddler looked at Zhao Wen nervously.

Zhao Wen said in a deep voice: "You can take it if you give it to you, otherwise, I won't come next time."

Seeing that Zhao Wen insisted on this, the peddler had no choice but to accept the copper coins.

Zhao Wen took two buns and walked out of Xuanzhen City while eating.

The ironworks are not very far from Xuan Town, but it still takes a lot of time to walk.

Half an hour later, Zhao Wen stopped outside the gate of the ironworks.

Zhao Wen looked at the gate of the ironworks, heaved a sigh of relief, and then walked in.

As soon as he walked in, Zhao Wen saw Song Yingxing who was walking around beside the blast furnace holding a pamphlet.

Zhao Wen looked at Song Yingxing, smiled slightly, and immediately went up to meet him.

"Mr. Song." Zhao Wen walked behind Song Yingxing and patted Song Yingxing on the shoulder.

Song Yingxing turned around and found that it was Zhao Wen, and hurriedly said, "I've seen you, my lord."

Zhao Wen waved his hand and said calmly, "You don't have to be like this, you don't have to be like this. With me, you just treat it as if you are going home, don't be too restrained."

"Thank you, sir, for your concern." Song Yingxing stuffed the booklet into his sleeve, then cupped his hands at Zhao Wengong, and said sincerely.

Ever since Song Yingxing came to Xuanzhen, he discovered the difference between Zhao Wen and others.

After the other chief soldiers took office, most of their minds were on soliciting money and gaining profits.

Not only did Zhao Wen not take money, but he also spent his own money to renovate the entire Xuan Town.

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."
