Emperor Hongzhi entered the carriage, which was completely different from what he imagined, and the carriage gave people a sense of comfort.

The Empress Dowager was already supported and sat down on the sofa.

Emperor Hongzhi sat aside, and that boy Zhu Houzhao was gone.

Fang Jifan felt that he was a little hatred at this moment.

So he became silent in a tactful way.

But the atmosphere... seems a bit awkward.

After a while, the steam train finally began to tremble.

Emperor Hongzhi was obviously frightened and subconsciously grabbed the handle of the sofa.

The Empress Dowager Zhou glanced at him and said leisurely: "What are you afraid of?"

Emperor Hongzhi's face turned red and he felt a little embarrassed.

The shaking in the car began to intensify a little.

Emperor Hongzhi felt even more uneasy and his face became a little bad.

Fang Jifan said with a smile: "Your Majesty has been riding this car for the first time and it is natural that you feel uncomfortable occasionally. Your Majesty will get better soon."

The train finally started to move and walked very slowly, but the rumbling sound was amazing. The sound of the wheels and rails was even more thrilling, as if the monster inside was beginning to live.

In the second carriage, Xiao Jing's scream came, mixed with the noise.

Of course, no one paid attention to him.

The Empress Dowager sat steadily, with no expression on her face, but a look of relief on her face, which dispelled Emperor Hongzhi's timidity.

Look, such an old lady is so calm. As the emperor, why should she be so embarrassed to be afraid?

Soon, the train began to drive slowly, first slid out of the station, and then became bright outside.

The train began to be under inertia, and with that pitiful power, the speed began to accelerate.

But no matter how fast it is, it is just a speed of more than 20 kilometers per hour. For Fang Jifan, it is as slow as a cow.

But its biggest advantage is that the power is continuous, and animals will be tired and the roads will be congested. However, the train only needs to follow the railway line and move forward at this speed at a constant speed.

Emperor Hongzhi turned his head and saw the sky light outside the window. Countless scenery was passing by in his eyes. The vibration finally began to decrease. I don’t know if it was a gradual habit or other reasons.

Emperor Hongzhi's face was filled with shock.

"Why is this car... driven?" Emperor Hongzhi finally couldn't help asking.

Fang Jifan hurriedly said, "Your Majesty, it is the perseverance, filial piety, and the original intention of seeking blessings to the people of the world!"

Emperor Hongzhi frowned, glared at Fang Jifan with a gloomy face, and said, "Speak human words."

Oh, why is this not human words? The Empress Dowager loves to listen to this.

Fang Jifan was a little unable to change, so he took a deep breath and instantly changed from the liberal arts student mode to the science student mode.

"Your Majesty, when the prince and his son checked the boiling water, the pot was heated and steam was generated in the water. He could lift the lid of the pot. Then he realized that the water vapor could actually produce force. His Royal Highness was extremely excited about this. Since this water vapor could produce hot air, and lift the lid of the pot, can more water vapor be generated like a windmill and a water wheel? "

"Windmills and water wheels rely on wind and water wheels, but these two forces rely too much on natural conditions. If God does not blow wind, this windmill will be useless. If you don't build a water wheel next to the water flow, this water wheel will be useless. But the heat can be artificially made. Over the past few years, His Highness and His sons have figured out this joint and have been in this direction, recruiting hundreds or thousands of craftsmen, spending countless gold and silver, and reading ancient books at the same time, trying again and again. Have Your Majesty discovered that His Highness is more taciturn than before?"

Emperor Hongzhi shook his head.

Well, that's a bit embarrassing.

"After spending countless efforts, the problem of using water vapor was finally solved. His Royal Highness, the Prince, used coal to generate steam, and the steam entered the transmission system along a special pipeline, which used piston movement..."

Fang Jifan kept explaining how the car operated.

In fact, even he himself had only a slight understanding of these difficult-to-understand mechanics knowledge, to be honest, was not what Fang Jifan was good at. He was more of it, just put forward a directional thing.

For the first time, humans began to use water vapor, or to build steam trains, and on this way, they actually took countless detours. Each detour was delayed for several years or even decades. Fang Jifan proposed a direction, and countless the smartest craftsmen in the world, led by Zhu Houzhao, could work hard in one direction.

Since ancient times, there has never been a shortage of skilled craftsmen here. Moreover, the previous engineering colleges and certain foundations were laid, coupled with the emergence of a large number of Francophone prisoners, the technology between the East and the West began to spread.

The Ming Dynasty in this era had a relatively open attitude towards external things. From the middle of the Ming Dynasty to the late Ming Dynasty, a large number of missionaries came here with new technologies. Many scholars and officials adhered to the attitude of learning and used their knowledge to improve many things.

Fang Jifan tried his best to explain the principle of steam trains in detail.

Emperor Hongzhi suddenly realized it.

At this moment, he no longer had fear in his heart.

This is how people are. People will be afraid of such a terrible monster suddenly appear, but once you tell him what's going on with this thing, oh, so that's it, it's just a matter of stopping steam, just like hot air lifting a teapot and using a lot of heat to make it move.

Emperor Hongzhi's face regained his blood color: "It's very difficult to make this thing."

Fang Jifan said seriously: "Your Majesty, the Crown Prince and countless craftsmen have spent two or three years of hard work. In order to overcome one difficulty after another, many people have worked hard, and some have even forgotten to eat and sleep. In order to continuously develop, many steel forging skills have been improved, and modeling methods have been improved... and many disciplines have been improved."

This is a great initiative no less than the Manhattan Project.

Its advantage is that in order to overcome many difficulties, countless mechanical manufacturing, woodworking, smelting, and many basic disciplines have made great progress.

These cutting-edge skills have created a steam train, but in fact, with the help of these, many machinery will emerge in the future.

Emperor Hongzhi was still angry just now, but at this moment, the train was still rumbling forward. The noisy noise and vibration, perhaps because the body had adapted, there was no more fear or discomfort. He frowned, but at this moment, he felt shocked: "This car only needs to be laid with rails to drive?"

"Yes." Fang Jifan said with a smile: "After laying the railway tracks, you can drive, and you can travel for eighty miles in one hour."

The speed is twenty kilometers per hour, that is, forty miles per hour. This speed is comparable to that of electric cars in later generations, and it can be stable and there is no traffic jam.

Fang Jifan was not satisfied with such motivation.

But Emperor Hongzhi's feelings were different. His first reaction was to take a breath of cold air, as if he was shocked by this speed.

With a quick horse and a whip, you can travel hundreds of miles a day, but the problem is that such knights have undergone special training but need to be continuously passed on to the post, which can only be used for the transmission of letters.

Fang Jifan said again: "However, the biggest use of this car is that it can carry tens of thousands of kilograms, or even hundreds of thousands of kilograms."

These words made Emperor Hongzhi confused.

One hundred thousand kilograms, not much, that is, only one hundred tons, is it a lot?

This train is simply a weak person in the train industry.

This load capacity is the load capacity of a train sheath in later generations.

But Emperor Hongzhi was completely shocked.

He was silent, thinking quickly in his mind.

"In other words, if you go from the new city to the old city, you can get 100,000 kilograms of goods, or... it is to carry a thousand people, and arrive in the morning and evening?"

"It's only forty miles, and you don't need to arrive day and night, just half an hour, and you can probably get there. If it's a passenger transport, you may need to stop the station in the middle, but most of the hour is enough. The son and the prince have already thought about it. Several trains will be added on this railway line, so that every half hour, there will be trains at each station."

It actually... can be added.

This is the real terrifying fortune.

It's okay if a car drives back and forth, if it's a number of cars, it's not like driving back and forth day and night, will the goods and manpower transmission of the new and old cities be almost seamlessly connected?

Especially in the old city, the canal is connected to the canal, which will deliver countless goods to the old city. This new city will not take advantage of the water transportation convenience of the old city.

Not only that, but also the movement of personnel...

Rumble... Rumble......

The roar of the train became surprisingly pleasant in the ears of Emperor Hongzhi.

Emperor Hongzhi's voice was a little excited: "Interesting, interesting. I have never seen such a delicate thing in the world. It's amazing to create this thing."

"Not many, from the development to the workshops specially built for it, as well as the manufacturing of steam trains, and the labor force, so far, it has cost nearly 30 million taels."

Well, Emperor Hongzhi's face turned pale in an instant.

The silver, 30 million taels, these two damn prodigal sons.

Fang Jifan continued: "But in the future, the cost will be greatly reduced by laying the railway tracks. Each mile can be controlled at the cost of 13,000 taels of silver."

"Apart from that..." Fang Jifan said happily: "Your Majesty, I have something forgot to report it to the land of this old city..."
