After the children in the family have a good home, the Ye parents can finally breathe a sigh of relief. The next thing they have to do is not a simple family fault, but a major event that can affect the life of the city.

For example, the city residents who defected to the city were thinking about the matter of dividing the land. According to the previous law, most people can participate in the division of the land this time, and both men and women can be allocated the corresponding fields.

But to be honest, in fact, the food produced in the field distributed according to the head does not make them full. At most, it can ensure that they can replenish carbohydrates every day through reasonable distribution, and the nutrition obtained in this way can be support their activities.

If the family has a large population, young and middle-aged people can go hunting. The prey they hunt and the various mountain products collected by women and children are good food supplements. After being pickled and dried, they can be preserved until winter. Since then, on the premise of satisfying food and clothing, they have begun to pursue eating well and sleeping soundly, that is, a better quality of life.

After the field was divided, everyone was very happy, which led to the prosperity of the market and their strong demand for farm tools, and also made the schematic diagrams of many simple tools in Ye Yu's mind come into play.

With the passage of time, everyone gradually realized that these inventions and creations that can promote the development of productivity brought them a lot of convenience, so they finally began to pay attention to these things. Since then, Ye Yu has been vigorously promoting the machine workshop. Finally, with the support of everyone, the building was successfully built. The owner of the workshop is Ye Yu himself. The people in the workshop include several carpenters, potters and blacksmiths, as well as students who have been taught by him and are quite talented in inventions and creations. Among them is the production of water. Ye Rong, who is in the third position.

To be honest, among these people, Ye Yu valued Ye Rong the most, mainly because he was so unconstrained in thought, and he was the only one who believed that the mythical stories Ye Yu said were true. real people.

But you can’t blame others for not believing it. If you haven’t seen it with your own eyes, who can believe that telephones, electric lights, trains, and airplanes are real.

When Ye Yu was talking on the phone that could transmit voices over thousands of miles and make instant calls, only Ye Rong listened with sparkling eyes, and no one else was paying attention.

After hearing this, Ye Rong asked with longing eyes: "Sir, how is this phone made? And that lamp, which has the same word as the phone, seems to have some similarities."

If he can think of this, it proves that he is quite talented, so Ye Yu answered him carefully: "Electricity is a natural phenomenon, and it is also a physical phenomenon. I told you about physics, if you don't remember it Go to the book, for example, lightning is a kind of electricity, and this lamp and telephone are made with electricity as the energy source."

Ye Yu found an elementary physics textbook from her book space. This book together with the chemistry book constituted the basic teaching material for the advanced class.

Ye Rong nodded and said, "That book is indeed a bit esoteric, and I can't quite understand many things."

Ye Yu replied: "It's really a bit of a spoiled for you, learn slowly, as much as you can learn, but if you understand a little, you can make a lot of contribution to our city."

As for why he didn't invent these things according to the book, the biggest reason is that it hasn't come yet. After all, Hope City has just had enough food and clothing, and a few farm tools that can bring convenience are just right. However, if he invents steam engines or electricity generation machine, it is very inappropriate.

What he wants now is to plant a seed about this matter in the minds of the students. After a few years or even decades, even if he has passed away, there will be someone who can inherit his mantle and ignite the fire of technology. .

Hearing this, Ye Rong was thoughtful, and made up his mind to study those two books after returning home, making sure to read them thoroughly.

Later, according to historical records, the steam engine jointly invented by Mr. Ye Yu and Mr. Ye Rong was regarded as the first germination of technology. As soon as the railway track was built, the first steam train in human history appeared. As the railway track was laid to the distance, the train connected many cities. Since then, the travel time has been greatly shortened. Promoted the development of productivity.

The hand-operated generator is also known as the second germination of technology. After the hand-operated generator, there are DC generators and two-phase AC generators. The construction of electric facilities, the electric lights that can illuminate the house at night like daytime, and the telephone that can carry out instant messaging thousands of miles away have all contributed to the further development of science and technology.

Of course, this is all decades or even hundreds of years later. Now Ye Yu and Ye Rong are still worrying about simple tools, they can't think of it so far away.

A group of merchants marched among the dense forests.

The leading team leader took out the map and looked at it, then pointed to the front and said, "Pass through here, and walk forward for a few hours to reach Hope City."

The deputy said: "I don't know if Jiwang City is a fairyland like Brother Ye said."

The team leader heard the words: "Anyway, we have what we need, and this trip should be able to earn a fortune."

Upon hearing this, everyone cheered up, yelling and driving the horse and donkey to move on.

Then the group of them walked forward for another half an hour, and then they saw a very spacious and flat asphalt road in front of them. The houses were neatly built on the road, and there were even small stalls pushing wooden carts for sale. There is a long line of people who eat and buy.

"This is?" the team leader murmured in shock.

Just when they were surprised, a person leaning on a tree asked, "Are you guys doing business in Hope City?"

The team leader nodded and said, "Yes, we are from Sunan City."

"Then you came by coincidence, we are short of cotton." The man said cheerfully, "You can see the gate of Jiwang City at the end of this avenue. If you bring a lot of things, or you are too tired, You can rent a few tricycles and go fast and comfortably.”

"Tricycle?" The team leader asked again suspiciously.

"Here," the man pointed to a car under him and said, "This is a tricycle. I can take you there by riding it. One can seat four or five people."

The leader looked at the strange car with some doubts. He saw that the car had three wheels, a handle in the front, and a space blocked by wooden boards in the back.

They didn't reply all the time, and the owner of the car didn't urge them, but only started to greet the people next to them.

"Do you want to take a car?" He asked a hunter who was carrying a whole wild boar. There were six people in total, each of them was very capable, and there were even wet bloodstains on their bodies.

"Sit." The leanest man standing in front took out eight copper coins, "Let two."

"Success." The owner of the car responded, and then called two young men and told them to push the car over.

After the two cars were pushed over, the group of hunters put the wild boar on one of them, and then jumped on one of them, sat on the car board and let out a long sigh of relief.

In the other car, there were only five people crowded to sit on it.

After they settled down, the two young men sitting beside the handle only exerted their legs and feet, and the car slid out at once. The speed was not slow, and soon only the back was left.

The people from Sunan City standing on the side were all dumbfounded and didn't react for a long time. After a while, the tricycle owner reminded them.

"Do you want to take a car?"

Hearing this, the team leader asked, "How much is the price?"

"Four copper coins for a trip. If you don't have copper coins, you can go over there and exchange them for things. The exchange point is open by the government, and the price is very reasonable." The owner of the car pointed them over.

The place he was pointing at was a green brick house with a window in the front, and a young girl was sitting inside. The girl was wearing a cloth covering half of her face, making it hard to see. Clear appearance.

Seeing a group of people approaching, the girl asked skillfully, "What do you want to use for exchange?"

Everyone in the caravan looked at each other for a while, and then someone took out a plain cloth and said, "Use this."

After the girl took it, she unfolded it. After carefully examining it, she found no flaws on it, so she said, "This piece of cloth can be exchanged for ten copper coins of ten denominations, that is, one hundred copper coins. You can exchange them for ?”

It only costs four copper coins to take a trip, but a piece of cloth can be exchanged for a hundred coins, which is extremely fair.

Sure enough, the team leader immediately agreed, "Change."

After the girl finished recording, she handed over the copper coins to them.

The team leader saw that she was not using a brush to record, but a pen with a brown shell, and the words written were black, so he asked, "What kind of pen are you using?"

"Oh, this is a charcoal pen. It is more convenient to write than a brush. You only need to go to the city and you will see many people selling it. You can choose to buy some. It is very comfortable to use." The girl began to sell skillfully.

"Okay, let's go in and take a look." The team leader nodded.

Everyone in the caravan paid for the rental car and sat in one by one, while their own horses and donkeys followed behind and were driven by others.

Because the entire road is covered with asphalt, they sit in the car very smoothly without any bumps. From time to time, empty cars can be seen coming. In addition to the three-wheeled car they are sitting on, there is another kind Two-wheeled vehicles, they learned from riders, these two types are called tricycles and two-wheeled vehicles respectively. As the name suggests, the vehicles are very simple and easy to understand.

The road was boring, and the cyclists couldn't stay idle, so I introduced them: "These are all made by the machine workshop, including the ground under your feet. Nowadays, the roads in the city are like this. They are flat and strong, which is very suitable for cycling. Riding a bicycle on it, many merchants from other cities have traded blueprints from us, if you are interested, you can also go and have a look."

"Did you just see the people who came back from hunting outside? Since they got this car, they don't have to carry the prey by themselves anymore, they just need to carry it over there. If they don't want to leave, they can rent a car and ask someone to deliver the prey first." go home."

As a result, the distance they travel will be greatly increased, and overall the advantages outweigh the disadvantages.

It took about two hours for them to finally arrive at the City of Hope. At this time, the sky was already dark, but the city gate was brightly lit, and many red lanterns illuminated the gate brightly.

They can enter after registering their names at the gate.

The city is busier than outside the city. A street around the lake is full of lanterns, and there are lanterns shining brightly on the lake.

"Oh, so today is the Mid-Autumn Festival." Someone suddenly realized.

"August [-]th, it really is." Others counted with their fingers, and then said with some melancholy: "I didn't expect this year's Mid-Autumn Festival to be spent outside."

"Don't think about it, let's find a place to live first." The team leader clapped his hands and said.

At this time, the person who brought them parked the tricycle at the designated place, and seeing that they were looking for a place to live, he said to them, "There is only one guest house in the city, and I will take you there."

The guest house is also set up by the government, and the price is very cheap. It only costs ten copper coins for one night, and the people hired are all from poor families. This is a kind of subsidy for them, and they can earn a few months a month. Money improves lives.

They didn't go to sleep for the first time after they stayed. Instead, they went to the Mid-Autumn Night Market outside, and they couldn't help themselves.

-

"Master Ye, the caravan envoy from Sunan City wants to buy asphalt, blueprints for two-wheelers, and tricycles." Lu Si reported.

Ye Fangzhu is also Ye Yu, he also served as the workshop owner of the machine workshop, and when he heard this, he said: "Just ask them to follow the previous practice."

"Yes." Lu Si responded and left.

After she left, Ye Yu rubbed his neck and said, "Recently, there have been more caravans coming to our place. It seems that the effect of the second brother and the others going out to do business has gradually begun to show."

Chu Xufeng massaged his back and said, "This is a good thing. Sooner or later, this asphalt road will connect all the cities."

Ye Yu imagined that scene, and then couldn't help showing a smile. He believed that one day his beautiful vision would be realized.

Some people say that history is the trajectory of human civilization, and Ye Yu is fortunate to have left a strong mark in history. At the same time, Hope City has become an ideal city that countless people yearn for.

End of the full text.

The author says:

When I typed the full text and finished the three words, I was relieved but at the same time felt a little sad. From May to September, I spent four whole months on this book. If the preparation time in the early stage is added, It's even longer.

Thanks to the little cuties who have been chasing all the way to the end. You have accompanied Xiaoyu and Axu to grow up and witnessed the ups and downs of this article. At the same time, thank you very much for forgiving my shortcomings in writing and narration. I hope we will meet again next time. See you with better writing.

Regarding the extra episode, I will wait until the Mid-Autumn Festival to publish it.

Finally, cuties can pay attention to the next novel about farming in the primitive era, "Cat's Farming Life" (title to be changed).

So bow, goodbye!
