The reason why three-wheeled bicycles were developed instead of two-wheeled bicycles was that people in this era could not understand how to ride a two-wheeled car. The tricycle is similar to the horse-drawn carriage, except that the animal power has been changed to a human-powered pedal cart, and it is easy for everyone to accept it.

Moreover, when officials have slaves in every household, it is impossible for them to ride their own bicycles, and it is more difficult to balance two-wheeled bicycles. So Du Jinning plans to get the three-wheeled rickshaw out first, and then build a two-wheeled bicycle step by step.

However, it was this group of officials who did the specific development, and Du Jinning only led the general direction, so the bicycle could be built, and the credit of these officials was really great.

Du Jinning saw that the official rode again, and he was eager to go up and experience it himself, Qi Muyuan hurriedly stopped her: "I'll take a look for you." ”

"I'm me, I'm me, and I'm me." Qi Ziqi raised his little fat hand high, for fear that others would not be able to see him.

There's no way, the height disadvantage makes people sad.

This bike has been improved many times, and now it is very safe, only in the matter of comfort, and when it was first designed, Du Jinning designed the back seat, and it is no problem to take two people in the back. So Qi Muyuan's long arm fished out, and put Qi Ziqi's child in the back seat.

"Sit down, don't move. Hold on to this place and don't fall off. Qi Muyuan said solemnly.

Qi Ziqi nodded obediently, and also assured with a serious face: "I must hurry, Daddy, don't worry." ”

Du Jinning couldn't help but laugh on the side.

Qi Ziqi is also very hard to experience the bicycle.

Zhang Hongwen watched there, and suddenly sighed with emotion.

In the past, Qi Muyuan was always cold, and he looked like he was not close to anyone. Although he still doesn't smile in front of outsiders, the warmth and tenderness in his eyes when facing his wife and children can't be hidden. However, with a strange woman like Du Jinning as his wife, and a smart and clever child like Qi Ziqi, no matter what kind of man he is, he can turn steel into finger wrapping, right?

Qi Muyuan rode around, didn't speak, and only looked at Qi Ziqi.

Qi Ziqi understood and hurriedly reported his riding experience to Du Jinning: "Mother, the car is very comfortable. Unlike last time, it was shaky, it made me dizzy, and it was very loud. ”

At this time, Qi Muyuan said: "It's more effortless than last time, and the pedaling is smoother." ”

When this group of people first built a car, they directly used an iron ring as a bearing, and then slowly changed it to two rings, and finally under the guidance of Du Jinning, steel balls were added to make a double row of angular contact ball bearings. This time, we are testing the effect of double row angular contact ball bearings.

The effect is naturally remarkable.

"Princess, Xia Guan thinks that this car has been successful." The official riding in front of him said excitedly.

Du Jinning would love to experience it for himself. After all, she has experience with modern cycling and can compare the differences between modern bicycles and ancient bicycles. This group of ancients did not have a standard for comparison, so they naturally felt that everything was good.

But she looked at Qi Muyuan and dispelled this thought. She didn't want Qi Muyuan to worry.

Besides, this could be the first generation of bikes. In the future, the second and third generations can be produced, and the profits are created in the upgrading.

"Let's make 300 cars out of this." Du Jinning said, "After you set the price yourself, report to the emperor to decide." ”

Officials were taken aback by the figure of three hundred.

"Princess, is three hundred too much? This thing is not cheap, and it is a new thing, so everyone may not be able to accept it. Xia Guan felt that fifty cars was about the same. ”

The cost of researching Eucommia ulmoides, steel, and bearings is not low. Halfway through, Hubu Shangshu didn't go to Zhao Yu to cry poor, and the opinions of the courtiers were quite big.

Later, Du Jinning was annoyed and decided not to pay the court, but to pay back the money originally paid by the household department out of her own pocket, and she would supply the household department with the money of these officials in the project team.

Not only is Zhao Yu unwilling, but the household department is also unwilling. This thing is really made, it is the same as Du Jinning's exclusive secret recipe for roasted tea, it is completely a money printing machine. The court can't make any profits, and it's all monopolized by Du Jinning, so what's the matter?

Du Jinning said to Zhao Yu: "I don't want to pay the cost to develop it, and I hope to produce results, how can there be such a good thing in the world?" Anyway, I don't want to be like a child, going to the household department every day to beg for money. "Just pick it and quit.

Hubu Shangshu was blushing and white for a while when Du Jinning said it.

In the end, the dispute ended with Du Jinning paying 30,000 taels of silver, accounting for 30% of the project's profits. This project includes not only bicycles, but also Eucommia ulmoides gum products.

Of course, Du Jinning never eats alone. She took out 20% of the 30% shares and distributed them to the officials of the project team, who voluntarily bought them. If you don't want to buy it, you can give it to other colleagues. If no one wants it, she'll wrap it up.

After Du Jinning analyzed the "money" situation for everyone, the officials of the project team more or less bought some shares.

One hundred thousand taels of silver can make a country's finance minister frown, which is not a small amount in ancient times. This includes hiring people to find Eucommia ulmoides trees, buying hills to plant Eucommia ulmoides trees, harvesting Eucommia ulmoides rubber, developing tires, purchasing expensive steel from the steel project team, and developing and producing various components.

In ancient times, when productivity was low, it took a lot of effort to do these things, so it cost a lot of money.

The officials of the project team knew the cost, and they themselves had a stake, so they felt that a bicycle would have to be sold for at least a few thousand taels of silver in order not to lose money. Therefore, I very much disapprove of Du Jinning's rash production of 300 vehicles.

"The cost of bicycles is high, and the R&D costs are taken into account. In the future, the cost of a car will not be much. The more you produce, the more profitable you are. ”

Du Jinning knew what they were worried about, and gave them an analysis: "I plan to sell this car for a carriage and a horse." Think about it, after the horse is bought, it needs to be taken care of by a special person, and it will get old and sick, the cost is high, and the service life is short. Our bicycle can be used for more than ten years, and it usually takes some effort and does not need to spend energy to serve it. Comparing the hatchbacks, if it is you, would you rather buy a bicycle or a carriage? ”

"Bikes." Qi Ziqi replied.

Everyone couldn't help laughing and echoed: "What the little county king said is right, he must choose a bicycle." ”

Du Jinning also smiled, gave Qi Ziqi an appreciative look, and said: "Besides, I plan to send two to the emperor, and the scholars of the three Qing and six departments will also sell one at half price." With their leadership, and the bicycle is not expensive, do you think the officials of the court will also sell one? Everyone rides bicycles, a certain official even rides a horse-drawn carriage, and the horses pull feces all over the streets, and everyone dislikes him, does he have face? ”

Seeing that everyone nodded in agreement, she said again: "Once the officials all go to the court by bicycle, will the rich families in the capital also have to catch the trend and buy one?" If we give another suggestion to the capital government Yin, let him advocate that all people travel by bicycle, and return the capital to a clean street to create a clean capital. Do medium-sized families also want to replace horse-drawn carriages with bicycles? With less horses, the court can not trade with Xia Jin at all, and looking at their faces, the emperor will definitely support it. Speaking of which, do you still think that 300 bicycles is too much? ”

"Not much. Not just more, but less. Speaking of which, I don't think 3,000 is more than a mile. An elderly official said.

Everyone nodded.

"The king of Chu has a thin waist, and the whole country is starving to death." The advocacy of the emperor and the leaders is not covered. What is the trend of fashion, just think about the tea ceremony of the eldest princess of Ning Kingdom. Now not only the entire Great Song Dynasty, but also Ilbenz and Goryeo are all practicing tea ceremonies. The money made from tea and tea sets is really a sea of money.

"Three thousand don't have to. Build 300 cars first, see if they sell well, and then ask someone to step up the construction. And the supply exceeds the demand, and the reputation of our bicycle can be regarded as a hit. Du Jinning said.

Where have the officials seen these modern marketing methods, and they suddenly feel that the princess is also very good at doing business.

Anyway, everything that listens to the eldest princess of Ning Guo is right.

"Of course, that's just my advice. The specific price has to be decided by the emperor. Du Jinning said.

"In this way, I will bother the princess to enter the palace and ask the emperor."

Du Jinning waved his hand: "Don't worry, since I'm here, I naturally have to take a look at the courtyard next door." ”

Saying that, she went to the next yard with Qi Muyuan, Qi Ziqi and Zhang Hongwen.

This is another project team that is developing a steam loom.

Because of the relationship between shared bicycles, Du Jinning still knows more about bicycles. But for the loom, I am not familiar with it. Therefore, this project team is more of an official and craftsman to explore on their own. Fortunately, there is no need to study raw materials like bicycles, even if it is difficult, after two or three years of research and development, we finally recently manufactured the first steam loom in the Great Song Dynasty. However, the effect is not very good, and we have to continue to improve.

"Princess, you're here." When the official in charge of this area saw Du Jinning coming, his eyes lit up, and he didn't wait for Du Jinning to say anything, so he directly ordered, "Turn on the machine and let the princess take a look." ”

After a while, the steam started the machine.

Qi Muyuan's father and son are not doing well, after all, they have accompanied Du Jinning to see it many times. But Zhang Hongwen's eyes almost popped out.

Without the need for people, the shuttle on the machine actually moved on its own, shuttling back and forth on the loom. Although the movement is not fast, and the weaving cloth is not very good, it is really weaving.

It's amazing.

Du Jin Ningrao is not good at this, but he has seen the machines of later generations, which are stronger than these officials and craftsmen in ancient times. So after watching it for a while, she began to discuss it with the officials and craftsmen.

While they were saying something they didn't understand, Zhang Hongwen asked Qi Muyuan: "This is also developed by the princess?" ”

Qi Muyuan nodded, his expression a little complicated: "Exactly." One after another things beyond the times were developed by Du Jinning, and in addition to being proud, his pressure also increased sharply.

Qi Ziqi's children didn't have any psychological burden, and said very proudly: "These uncles and uncles all praise my mother, saying that if there is no guide from my mother, they can't make it at all." ”

Zhang Hongwen raised his eyes and stared at Du Jinning, silent for a long time.

After Du Jinning led them out of the Ministry of Industry, Zhang Hongwen asked: "Princess, if we are hired by the court after doing well in the exam, will we create machines like these officials?" ”

"That's right." Du Jinning said, "As you can see, we are carrying out a reform. After these machines are built, they need someone to manage and maintain them, and these need to be manpowered. At the same time, we will be developing more machines, which will also require those of you who like to study things. ”

Zhang Hongwen's eyes lit up, and he said excitedly: "I must take the test hard, strive to be admitted, and be your subordinate." Thinking that these machines would come out of his own hands, he couldn't wait to be one of them.

"No, it's the emperor's subordinates, a member of the court." Du Jinning said.

Their background will be worse than those who have been admitted to the imperial examination, which is equivalent to the same jinshi, but they are still court officials and technical officials.

Zhang Hongwen was in a hurry to go back to review, said goodbye to a few people, and went straight back to the hall.

Qi Ziqi was held by his father's little fat hand, and he looked up and said, "Mother, I also want to study hard and build this kind of machine." ”

"Good. Come on, brother! Du Jinning waved his fist at his son.

"Go home or where are you going?" Getting into the carriage, Qi Muyuan asked.

"Let's enter the palace." Du Jinning said, "I want to discuss the pricing of the bicycle with the emperor." ”

"I miss the fifth prince's brother." Qi said to himself.

Du Jinning touched his little face: "When you are six years old, you will enter the palace to be the companion of the fifth prince's brother." At that time, I can play with the five princes and brothers every day. ”

Qi Ziqi was frightened: "Then I can't see my father and mother?" ”

"No, go in the morning and come back in the evening. When I go home, I can still see my parents. Du Jinning said.

Qi Ziqi breathed a sigh of relief: "So that's the case." Stretched out his chubby hand and patted his chubby belly, "Then I'll be relieved." ”

Du Jinning couldn't help laughing: "Is your heart in your stomach?" ”

"That's right." Qi Ziqi nodded, "Mother, didn't it say in the book "Farming Notes" you wrote - his hanging heart was finally put back in his stomach. It can be seen that the heart is in the belly. ”

"Hahaha......" Du Jinning laughed and reached out to pinch his little chubby face, "Brother Qian, why are you so cute." ”

"Right? I also think I'm the cutest kid in the world. Qi Ziqi was praised by his mother and was very proud.

Qi Muyuan couldn't help but splash him with cold water: "But your imperial uncle said that your fifth prince brother is the cutest child in the world." So who is the cutest of you? ”

Qi Ziqi looked at his father like a mentally retarded person: "Daddy, don't you understand this question?" Every parent feels that their child is the cutest of all. ”

Du Jinning laughed again, touched Qi Ziqi's head and said, "Smash, what you said is really right." In the eyes of your father and mother, you are the cutest child in the world. As he spoke, he poked Qi Muyuan's waist again.

Forced by his wife's obscenity, Qi Muyuan had to say: "What your mother said is right. ”

Qi Ziqi sighed and glanced at Du Jinning's stomach very melancholy: "Aunt Yan said that there are younger brothers and sisters in my mother's belly." When they're born, I'm not your cutest son. ”

"Quite possibly." Du Jinning nodded, "Whoever of you is the best and most capable, who is the most cute, and the others are the second cutest." So Brother Qi, you have to come on, you are older than your younger brothers and sisters, you can't let the little ones catch up. ”

As soon as Du Jinning said this, Qi Ziqi suddenly felt like he had been beaten with chicken blood: "That's no problem, I'm definitely the first cute." ”
