When I come back from Lanling Mansion, I always pass by the pond behind Zhuangzi. Almost every time I can see the busy figure of Yun Yatou, clearing the pond, draining the water, drying the pond mud, and more than a dozen gentlemen are jumping up and down on the edge of the pond. The girl and Yun

The stewards of the house stood aside and gave instructions, changing manpower from time to time.

According to the current financial situation of the Yun family, as long as she is not very busy, Girl Yun can enjoy the happiness at home and leave the outside affairs to her servants. Standing by the pond in the twelfth lunar month is enough suffering, even if the sun is low.

I feel the wind blowing from the pond on the yin side, blowing on my body like a knife being pulled across my body.

Every time I see this, I can't help but feel that the two boys from the Yun family are too ignorant. Logically speaking, I shouldn't interfere with other families' affairs, but it's outrageous for two strong young men to eat, drink and have sex at home while it's freezing cold and ask a weak woman to come out and suffer.

!My dear sister, you have endured all kinds of hardships to support your two younger brothers over the years. Others don’t know these hardships, and the younger brother still doesn’t understand?

Finally, I have grown up and my family business has been established. It is time to share some of the burdens with my sister and argue with me. Why don't I have a conscience? No wonder the fourth child can't see it. Even Ying occasionally hugs Yun Yatou in private.

Unfair. Of course, when Ying feels unfair, Butler Qian will immediately have opinions about the future successor of the Yun family. Everything changes its taste once it comes out of Butler Qian's mouth. The two unscrupulous boys of the Yun family who are lazy and lazy are now notorious.

"It's a pity. If this girl had been a boy, the Yun family would have been prosperous a few years ago." Butler Qian was leading a few people from the local area to buy some land. When he saw me coming, he immediately pointed to Yun girl by the pond and became a local official.

He began to express his dissatisfaction and said to everyone: "You guys don't know

He said, many years ago, the Yun family suffered a fire from heaven, and both parents died with no property and a debt. So what would it be like for a little girl to drag two younger brothers? How painful! If it hadn't been for Mr. Hou and his wife to help pay off the debt, it would have been long ago

If you let the creditors who came to your door sell it, you wouldn't be where you are today."

Butler Qian is a prominent figure in the local area, and he made several petty officials greet me with a flurry of courtesy after saying something. He kept talking nonsense about civilized martial arts, and blessing the common people, which made me very happy, and ordered Haosheng to entertain these unworthy people.

Senior officer, this is what it should be. No matter how prominent the Wang family is, local relations must be maintained well. Everyone's words make money, and we can't put on airs in the countryside to make others fall behind.

As soon as I got away from here, I turned a corner on the trail at Tangkou and was discovered by Yun Yatou. She waved to me vigorously and ran over. I was just about to tell you to do your work... I remembered that this line was plagiarized by Zhang Fu, and I thought

Changing the greeting, the girl has already arrived.

"You don't rest even in the twelfth lunar month?"

The girl's face was blown dark red by the pond wind, and she carried a basket with a few sections of fresh lotus roots and handed them to me. Yun girl is interesting, she gives water chestnuts when they are in the ground, and lotus flowers on days when lotus roots are produced.

The food is always produced in one's own fields. There is no need to be polite when meeting in the countryside, and it has nothing to do with each other's status.

"I can't let it go when I talk about spring. My little girl is used to being busy and can't sit still at home. Let's talk about it and take a look. It will last a day." Yun Yatou took a matter-of-fact tone, picked up the messy hair in front of her forehead and smiled generously,

"Are you just on a business trip?"

"Oh, it's not bad at all." He put the basket on the ground casually. When he had nothing to say, he asked, "Brothers, are you planning to get married after the new year?"

"Chun Busy, just go over there and do it," Yun Yatou looked towards her home with a happy face, and asked cautiously: "I wonder if the eldest brother of the Wang family will..."

"Go, I must go. My wife and I are going. This is a great event for our village, and we cannot delay it. As soon as your brothers get married, you will be able to let go of this burden. It is time to be relaxed. It has not been easy these years. It is also time.

Let's find a suitable family and enjoy a happy life." As he said that, he subconsciously looked among the group of gentlemen by the pond. Sure enough, this idiot Xie Bao was there, squatting on the corner of the pond for who knows what, apparently hiding from me.

Girl Yun was embarrassed by what I said, her face turned purple with embarrassment, and she said in embarrassment: "The eldest brother of the Wang family is joking. There is nothing to worry about. At this age, I don't dare to marry anyone who is suitable. I still have the surname Yun. My younger brother

We are busy with studies. We dare not distract them. The two unmarried sisters-in-law are daughters of good families. They can't do anything in public. They can only help with the family business for a while, but they don't dare to think about anything else."

What does it mean to be a daughter of a good family? A girl like Yun Yatou is a daughter of a good family. You can’t choose anyone from far and near. Age is not a problem. There are only two places to choose from. She has been exposed to the wind and sun these years.

She has the tenderness of a lady, is not squeamish or pretentious, is simple, generous and capable. Whoever marries her will enjoy the blessings. Where can I find such a good girl?

He smiled and shook his head, "It's time to think about it for yourself. It's time to leave the family affairs to them. There is no reason for my sister to have to work for her whole life. It's unreasonable."

Girl Yun shook her head and hurriedly explained: "You misunderstood, misunderstood. Everyone is busy with their own things..." Just as he was saying that, the handsome guy Zhang Fu appeared on the road like a horse, and Girl Yun stood next to me and started waving again.

"You're busy with your business, but don't come here!" Zhang Fu, this idiot, doesn't have enough brains. Girl Yun and I were clearly standing on the road, but he still made such a serious statement, which made Girl Yun a little undecided and didn't know what to do.

You shouldn't laugh.

"Come here!" After all, we are related to me, but my IQ is really not worthy of this outfit. How embarrassing. He picked up the lotus root basket on the ground and threw it to Zhang Fu, "Send it home and wait for me in the study."

Zhang Fu helplessly twitched the corner of his mouth towards Yun Yatou, and said gesticulating: "My younger brother is heading towards the Yun family, the two students are still waiting, and they have important matters to discuss with Miss Yun family..."

"What are you talking about?" He looked at Yun Yatou and then at Zhang Fu. He didn't pay attention for a few days and it got to the point of breaking into the house. There are important things here. Xie Bao, the two idiots, are still pretending to be laborers on the corner of the pond. They are doing evil.

.

"Little gadget," Zhang Fu saw my strange expression and Yun Yatou still coughing like whooping cough, so he quickly explained, "The gadget for pumping water is different from what you think."

"What am I thinking? Whose house is the water being pumped?" I also learned to take cover. The pond is full of water. It doesn't make any sense to go to Yun's house and pump the water.

Girl Yun was so embarrassed that she hurriedly interrupted Zhang Fu's explanation, "Brother-in-law of the Wang family misunderstood again, it is indeed a water pumping machine." Pointing to a lotus pond in the east, she said: "It is higher in the north and lower in the east. It is easier to fill water in spring, but it is easier to drain water in early winter.

It’s difficult, especially in the dozens of acres of ponds at the east end, even if the irrigation canal is used,

The water was not drained cleanly. In the winter, it took a lot of effort to clear the pond with knee-deep water. Over time, it was easy to get sick. The winter before last, my brothers followed Mr. Zhang to the engineering school to broaden their horizons and saw the pumping equipment used on boats. They got ideas.

.I just want to imitate one set to help drain the lotus pond at home.”

"What machine?" Girl Yun explained like this, and her credibility immediately increased. She looked at Zhang Fu and asked, "Why don't I know? Is it easy to use?" The Wang family also has many lotus ponds. Although the management is not as meticulous as the Yun family, they have pumped water.

There are some things that can improve efficiency and allow farmers to soak in water as little as possible. Dr. Zhou often reminds them to beware of joint diseases.

Zhang Fu breathed a sigh of relief, "It's a gadget. It's a machine that the shipping group brought back from some small country on the other side of the sea. It was originally used to pump out the water in the cabin when the ship was sailing on a long voyage. But the Tang Dynasty's long-sea ships were huge, so

Although the small mechanisms made by foreign countries are exquisite, they are like a drop in the bucket on a big ship, so I plan to improve them accordingly."

"I don't understand. Please explain it more clearly." The competitive spirit overcame curiosity. I taught Zhang Fu. Now I can't bring something weird to teach the teacher. Even if he is better than me, he still needs my permission. No.

To be silent is to be treasonous.

"It's hard to say whether it's a small gadget or not." Compared with the new crossbow machine, this kind of small machine is obviously not the focus of Zhang Fu's concern. Otherwise, other sailors have brought it back for several years without any action. Now it is thrown to Yun

The young boy of the two families went to play with it. "After several improvements, it is easier to use than before, but it will not be easy to clean the water from such a big pond." As he said this, he looked at Yun Yatou and made a few small gestures.

.

Girl Yun understood and quickly invited me to her house to help teach her. Firstly, she could avoid suspicion, and secondly, she could get rid of the rumor that her brothers were doing nothing, killing two birds with one stone.

Just look at it, as one of the shareholders of Ocean Caravan, the more improvements you make, the more profits you will make. This is your responsibility.

You wouldn’t know it if you didn’t see it. I was shocked when I saw it, it was hand-cranked! Both boys were very strong, and they became more and more excited when they saw me. They put the water pump like a bathtub in the Yun family’s small pond and shook it hard, and the water flowed smoothly.

The water gutter on the edge of the barrel flows out gurglingly. If the gutter is lengthened, the water can be transported to a distant place. It would be quite magical.

Let the two boys pull it apart and try it in person. The feel is just right. Because of the limited strength, it is difficult to shake it. Looking from the top, the inside of the barrel is a propeller blade with wooden boards pierced diagonally. There is no sealing or other height.

The problem of precision is that the paddle is rotated at high speed and the pressure generated instantly when the water enters the container is used to complete the entire work. It is a bit like a centrifugal water pump. So you have to shake the handle crazily. Once it slows down, the water will flow backwards.

go back.

"How do you use this on a boat?" Now I only care about this. As for whether there is water in Yunjia's lotus pond, it has nothing to do with me.

"Small boats are easy to handle, but big ones are difficult." Zhang Fu squatted down in front of the water pump and put down the barrel with force. "The key is not to do too much." As he said this, he shook the wooden handle and started to spin. The rotation speed increased, and inside

The wooden board made a loud noise as it hit the wall of the barrel, "It's not durable. The wood will rot easily if it's soaked in water for a long time, and it will dry out easily once it's out of the water. It's okay to say it's small, but the bigger it is, the more likely it is to cause problems."

"Show me the prototype brought back from overseas. I want to know how this thing works on a boat." The thing in front of him was obviously tailor-made for his lotus pond. It looks very hanging, but it won't necessarily work on a boat.

It is better than the existing drainage methods and depends on other people's professional products.

Zhang Fu was very puzzled. Seeing that I was eager and could not refuse, he personally led someone to drag the big guy into the palace that night and placed it in the yard like a coffin.

After researching for a long time, I found nothing new. The only difference is that several transmission devices in this coffin are made of metal parts, which are limited and can be more wear-resistant than wood ones.

"Would it be more durable if I replaced it with copper parts?" He asked his subordinates to light a lantern for lighting, and asked a few people brought by Zhang Fu to help dismantle the water pump. "Wouldn't it be too much to replace the rocker arm and this spindle with copper parts?"

Is it difficult?”

Zhang Fu frowned and shook his head, "Once we start to improve it and plan to replace it with copper parts, I'm afraid it won't be a small expense. Now the manpower in the engineering school is limited, and the armament is a big expense. I really don't have the extra energy to do water pumping.

.”

"What's so difficult about this..." He stopped as soon as he said it, his tone was too much. This is not the 21st century. It is really laborious to do this under the current conditions. It is not just a matter of replacing a few metal parts. Once the ship is used

This is a life-saving machine. It cannot be finalized without repeated testing thousands of times.

, this not only requires expenses, but also the preparation and materials are enough to keep the engineering school busy for a while. Seeing that Zhang Fu was a little depressed, he quickly apologized, "I'm sorry. I lost my temper. Help me make a plan to see how many suitable manpower will be needed. It is approximately estimated

If you can't come up with the expenses, let the Dongfang Navigation College handle it."

Zhang Fu immediately became embarrassed and replied: "I don't dare, I don't dare. Since I sent the engineering student here, there is no reason to pass it on to other families. Manpower, since you value it so much. I might as well take charge of it myself. The Yun family

The two students can just follow their younger brother to broaden their horizons in engineering. As for the expenses, you know that the budget for next year has been submitted before the twelfth lunar month..."

That's no problem. Zhang Fu and I both work under the same boss. Boss Lan has the advantage of having more money. Zhang Fu hurried back to sort out the supplementary budget and record it. I went to boss Lan's house to talk things over; as for laborer Xie Bao,

, look at him lazily. Let him fend for himself. This guy doesn't need human rights.

There is no use in asking for human rights, it is not as good as the reality of water pumps. From the lessons learned from the two large ships that crashed many years ago, large ships have the advantages of large ships, but the corresponding problems have not been properly solved. One is the structure of the ship body

The improvement is to improve the drainage efficiency.

As early as the Sui Dynasty, semi-sealed and compartmented hulls had been used to improve the safety of ships. Subsequently, if the water was not drained in time when encountering strong winds and waves, it would be difficult to keep the ship stable. Drainage problems have become a major issue in shipbuilding.

A major bottleneck in the industry. If more efficient water pumps can be installed

All the problems of the ship will be solved, the hull will be built larger, and it will be able to travel farther, and the ocean returns will be more abundant. The rich returns will stimulate the rapid development of the shipbuilding industry, and the Wang family... of course, the inner government

They will become even more greedy, and the virtuous cycle will begin again.

After some persuasion on my part, Zhang Fu finally understood the value of the water pump. He nodded frequently and couldn't help but admire it. In short, he acted very eagerly, which at least made me feel that he was trying to make himself eager.

"It seems you still don't understand." I smiled first and raised my hand to pour him a glass. "It sounds nice to say it, but it's completely different when you think about it. At least most people can't understand the effects of the sea.

benefits.”

Zhang Fu drank it all in one gulp and nodded. "At least I can't feel it. Although I have brought back a lot of rare objects from overseas in recent years, everyone who travels by sea is so fat..." He quickly put a gag on his mouth when he said this.
