Looking at the people in front of him, Yang Heng felt a little ashamed. Oh, am I too irresponsible? I just left you with the task and left you alone. You have done so well. And, just such a thing with a huge friction coefficient, you actually pushed it away.

"Nephew Xuewen, don't worry, please do it. I'll make sure to lay it flat within three days. What, you still have requirements, you can do it, don't worry."

This is the third uncle who beats his chest and makes a sound. Since that's the case, I'll take a look in three days. However, Yang Heng will not be idle in these three days. He wants to study how to let five horses pull the car together, and to pull the train car. Is it better to be two in front or two in the back? How is the movie that makes the flying? But there are not five horses on the top. Forget it, don't think about it. Let's talk about it at that time. It's just an experiment, not a permanent horse to pull the train. This is not reliable, right? Also, professional things are for professionals to do, so you can't drive this horse.

…………

Three days finally arrived. Yang Heng came to the railway again. Only then did he realize that in the raised stone, he was actually paved with loess, and two railway tracks were left on it, which were there alone.

"Big nephew, what do you think? But I think the route of this track is shorter and it is more troublesome to repair. If you run, it is probably the end of the horse before it can run." Uncle San felt a little regretful.

Yes, the horse is pulling the car and just running. Then it will slow down and brake. If you are not careful, you will run across the boundary. Although there will be no car destroyed or people killed, the carriage will be derailed and the horse will be injured. That is certain.

"Well, don't worry, Uncle San, if the verification is appropriate, then you can continue to repair it. At least you have to reach the vicinity of Chang'an City. This is enough to have more than 30 miles. At that time, we will be able to transport goods, so that we can take a tour, and we can also make a new look. Now, Brother Da, it depends on you."

"Don't worry, little husband. Isn't it just used five horses to pull it? This is a little meaning. I can definitely catch it very well." Brother Da was very excited to see this scene. Such a big car and even a special route, and it was still running on the rails. It was exciting to think about it.

"Brother Da, remember, after the speed starts, you must lower it and stop, otherwise you will derail and there will be horses injured."

As the elders of the Yang family, it is not an important thing. Yang Heng basically won’t ask them to do things anymore. They are all responsible for their favorite stash. They are idle and brag and chat with some newcomers. But why did Yang Heng call him again? Because after thinking about it, Yang Heng was particularly at ease with these old people.

Sure enough, it was still reassuring that Uncle Da was doing things. He placed the five horses in a short while. "Young man, is it started?" "Start." Yang Heng gave the order, "Go." Uncle Da shouted.

Then I felt the chassis under me slowly began to rotate and shaking. What a familiar feeling, and there was the wonderful sound of the iron wheel rubbing against the rails. Now you are missing are the loud whistle and the sound of the deflated air, but there is a chaotic sound of horse hooves, "Take," and the horse's chirping "Heryl..."

"Big nephew, don't say that this thing is really good, it's fast and has a lot of pulling. Look, there are so many people on it now, and the horse pulling is so easy. It's much lighter than a carriage, and even more stable. If there is a shed, it would be even better."

Why did Uncle San say this? It turns out that this car is just a large flatbed now, a flatbed car more than 40 feet long.

"Well, uncle, I will install a carport and even glass, so that people can look outside, and can also visit."

"Glass, how expensive it is, just a small piece of money, it costs a lot of silver." Wang Feng, who was next to him, interrupted.

How many people have been pulled in this car? There are only more than ten people at present. It seems that if this car is installed, it may be able to pull more than 30 people. It is a face-to-face round seat, which requires tea and even other things. This belongs to a special car. This is Yang Heng’s current plan. Ordinary people, don’t think about it now. They are a group without money, and they will only have their seats after the real train is born.

"So, Uncle San, I will give you half a year. According to this standard, we will go south to the location of the station we reserved outside Chang'an City, and to the north, how about it when we arrive at the princess's village." Cheng, my eldest nephew, I promise to complete the task.

"Where is Uncle Fifth." "Your third uncle has completed it, can't I finish it?" "You two, continue to build a new chassis, but it's not like this. The experiment has been done. You know what shortcomings are. Therefore, we must follow my initial drawings and use springs. Although love is one of two wheels, it is just two wheels on one side. The specific ones are on the drawings, but how to reinforce and how to strengthen it requires you two to grasp it. My requirement is that according to this running method, you will have to run for at least one year without any faults, and it must be easy to inspect and replace broken parts."

"Don't worry, boss, we will definitely do this, so should this car be dismantled?" "No, this will never be dismantled. This is our construction history and needs to be used now. After it is retired, we have to have a special place to display them, and even write instructions for people to visit." Yang Heng had already started to fantasize that maybe in a few hundred years, this car would change to another train, but people didn't want to change it.

"Brother Da, the next thing you have to consider is that there may be two carriages in the future, so five horses may not be enough. There will be brakes on them. You also have to find a complete set of ways. This way of pulling a horse may last for a few years, or it may be a short train for a lifetime. Remember, you have to train a few apprentices as quickly as possible."

"Don't worry, little husband, let me leave this."

Yang Heng’s idea is very simple. Now that he uses Malay to pull, he has been considered a successful experiment. If he has a real steamer head, he might specially make a special horse train with two or three sections, which is for travel, which may be a face-saving thing.

"Brother, brother, we are here. Why are there such a fun thing without us?" These children, and who are they, Changle and Yu Zhang, also came to watch the fun.

Well, these children cannot be seen as ordinary children. Maybe they will have new ideas. "Everyone is ready to sit down, don't fall down. It's very dangerous to fall down. After sitting back and forth, we will talk about your feelings and your suggestions."

OK, Yang Heng assigned them tasks directly.

"Brother, this is what kind of train you promised Grandpa the Emperor, but why didn't I see the fire?" This was not only Yu Zhang's question, but even the children looked at Yang Heng with a gaze, wondering how he could explain it.

"This is a semi-finished product. Have you not seen the one who pulls the cart? The train is naturally a fire-burning car. However, I have not developed that kind of power yet. It will take at least three years to succeed. Don't worry, I promised the Supreme Emperor to make it within five years. At that time, it was not such a car, but a car that was longer than ten and twenty cars."

"Oh, that's so exciting. By the way, brother, is that speed so fast?" "That's happier. One day and one night, you have to run at least 600 miles."

Yang Heng cannot say too much, but the speed of more than 30 miles per hour can still be achieved, otherwise it will be a time traveler. However, it is possible to have a speed of 60 miles per hour. However, safety issues along the way must be considered. Don’t be on the railway at any time. In this experiment, Yang Heng specially arranged a few horse-riding guards to run in front, for fear that someone would hit him. (To be continued...)
