For decades, Gongsun Du has never forgotten his desire for the steam engine, although he was also worried about unnecessary changes caused by it, but every time he thought of everything two thousand years later, his heart was full of pain, and he only had one thought in his heart-

If this leads to endless chaos and goes into other ways, then all kinds of sins and karma will be mine!

With this in mind, the research on the steam engine has always continued, and until Huang Fei arrived, he participated in it, and it remained the same.

Last year, when Gongsun Du was planning to go south, he didn't notice that Huang Fei hadn't returned for many days, and when Gongsun Xu (Huang Yueying) talked to him, he took the child to find his mother with black lines!

Finding Huang Fei, Gongsun Du was shocked that the Gaiying steam engine had been completed and was conducting the final test.

It was only because Huang Fei hoped to report to him after getting the final result, so he did not return for many days, and there was no news.

At this time, Gongsun Du was not angry, but asked to complete the test as soon as possible, and then hang the box for trial operation to ensure safety.

A year later, the train has completed its final inspection. Not long ago, a large army transportation was completed, that is, the vanguard of the Western Expedition, Kebineng Division!

The first human transport in the true sense of the word has been completed!

If Gongsun Du is gone, there is no need to think about it, it will definitely not be his turn for the first time. In fact, even if Kebineng led the army to the Western Regions safely, and it was not a one-time transportation, the ministers were still worried, and it was only because of Gongsun Du's repeated insistence that they finally made the trip.

"Well, not bad!"

When he arrived at the station, Gongsun Du first took a serious look at the train, and saw that although it was completely different from the image of the train in later generations, it was not bad, so he praised it, and then walked to the arranged carriage.

"Yueying, Bra, let's go, get in the car!"

Huang Fei and Bula were also taken by Gongsun Du, not because they had some unreasonable ideas, but because Huang Fei was actually the "father of the steam engine", and it was necessary to experience it on the spot in order to make better improvements; And Bula took the opportunity to go back to his hometown to see-

Save your family!

As for the war or something, it's not that Gongsun Du looks down on people, but that the countries of the Western Regions are really not as powerful as they imagined, and they have a natural disadvantage, that is, the number of armies is too small!

Entering the carriage, there are a total of eight rows of seats, with two seats in the middle, and it is a one-plus-two arrangement, but the seats are significantly larger than the other seven rows. The other seven rows, for six, and the three-plus-three situation, have forty-two. This adds up to a total of forty-five seats, which is a total of ninety-five.

By the way, the laying of the track was much earlier than the steam engine, but it was completed less than a year earlier. Moreover, Gongsun Du took into account the limitations of the times to avoid accidents, and used an eight-foot wide gauge in the problem of track width.

So when the train moved, Gongsun Du didn't feel much turbulence, and in this regard, it was almost comparable to later generations. However, if the speed is the same, it will definitely not work. (Not to mention the advantages of broad gauge, stability must be the first priority)

In the sound of "clang" and "clang", the speed of the train gradually stabilized, and Gongsun Du couldn't bear it anymore and stood up directly.

Dian Wei and the others jumped down and stood up, but fortunately, these people are all real elites, and they have had a period of time to ride the boat, and they can hold it steadily, and there are no accidents.

Gongsun Du's eyes swept over and said, "What are you doing?" Sit down! This is on the train, do you think there can be an accident? ”

Dian Wei and the others smiled embarrassedly, and then sat down. However, they were also curious when they took the train for the first time, and they all stretched their necks to look out, and kept saying something in their mouths, although they didn't make a sound, but they could understand that they were saying good things by looking at the looks on their faces.

Gongsun Du shook his head, ignored Dian Wei and the others, and stepped to the side of Huang Fei's second daughter.

"Bra?"

Huang Fei, as the leader of the steam engine, is nothing, but Bra is different, when she feels that she is moving under her, she is so frightened that she can't give up, so Gongsun Du saw that Bula's eyes were closed, and his hands holding his skirt were a little white.

Huang Fei smiled helplessly and said, "Your Majesty, Sister Bula may be a little scared, Your Majesty should comfort her!" ”

After speaking, Huang Fei also stood up, walked to the position of Gongsun Du before and sat down.

Gongsun Du nodded, sat down next to Bra, and then stretched out his hand and said, "Bra, it's okay, I'm here!" ”

I have to say that at this time, men are really women's heavens, even if the essence is a little different, but only the royal family is like this, so when Bra felt someone holding his hands, he wanted to scream, but when he heard the sound, he stopped, and subconsciously leaned over.

Gongsun Du smiled helplessly, and continued to comfort him in a low voice, forgetting even his original plan.

After talking for a long time, Gongsun Du's mouth was dry, and Bra cautiously opened his eyes a little slit. She first looked at Gongsun Du, and saw that it was still the same Gongsun Du, and she calmed down a little without the slightest change, but when she turned her head to the side, she saw the trees outside the window brushing back, and she closed her eyes in fright.

Gongsun Du was really helpless, shook his head, and said, "Bra, haven't you ever ridden a horse?" Think about it, is it the same when you ride a horse? ”

Bra thought for a moment, then opened his eyes again.

Gongsun Du couldn't help but shake his head again when he saw her cautious appearance, and at the same time he was glad that the speed of the train was not fast now, otherwise even if he didn't scare Bula miserably, he would probably vomit very badly. (Not to mention the past, but now there are many people who are on the train, and if they keep looking at the nearby trees, they will feel nauseous and want to vomit, which is not nonsense.)

Then, Gongsun Dudianwei sent some prepared drinking water, drank a few sips, moistened his throat, and recalled the train in his previous life-

"Beer, drink, mineral water~"

"Peanut melon seed eight-treasure porridge~"

The sound is still in my ears, but I can't go back.

Beer drinks are not counted, and mineral water may not be as good as stream water, so forget it. But peanuts and melon seeds can be made, and the eight-treasure porridge is inconvenient to carry, so forget it.

Gongsun Du pondered that if he took the train again in the future, he must get some fried peanuts and fried melon seeds.

Not much to say, peanuts have always been available in the Central Plains, but the yield is average, but there are them anyway. There are many kinds of melon seeds, but they don't seem to be in the Central Plains and belong to exotic plants. But don't worry, when the Indian Palm people sacrificed to Mei Zhong and came to Liaodong, they brought their holy relics, one of which was sunflowers.

Why are sunflowers one of the sacred relics? Guy's round face is always chasing the sun, which is a strange behavior that no other plant has. Obviously, everyone is enjoying sunbathing together, but you are enjoying chasing others and catching up with your heart, so you deserve to be loved and kicked!

Pingsuli, Gongsun Du also eats melon seeds, but he doesn't like it very much, so he ...... But now it seems that it's not that I don't like it, but I don't have that atmosphere, it's like drinking, you have to have snacks, there are a few brothers together, that taste, tsk, you don't have to blow it at all, okay!

Bra's mood stabilized, and Gongsun Du also moistened his throat, and only then did he have time to estimate the speed of the train.

After looking out the window for a long time, Gongsun Du had a result, which was about fifty miles per hour (slightly faster than the earliest train).

Although it is still very slow, the train can move forward day and night, and it is in a straight line, so it is still the train faster, and the consumption of war horses is also reduced, and the soldiers have enough rest, as long as they arrive, they can be put into the battlefield, which is very good!

Gongsun Du clapped his hands with great satisfaction, and then said to Huang Fei across the aisle: "Yueying, the speed of the train is not bad now, but there is still a lot of room for improvement, so your next goal is to increase the power of the steam engine, and increase the speed as much as possible while maintaining stability." Only the faster the speed, the faster the speed of sending troops and transporting supplies, and the greater the deterrence of Xiaoxiao. ”

"Well, we've thought about this issue too, but we haven't had a direction." Huang Fei nodded affirmatively, and then said, "Is there any other way besides increasing the power of the steam engine?" ”

Gongsun Du thought for a while and said: "As the speed increases, the degree of bumpiness may not change much at the beginning, but when it reaches a certain value, it will definitely be more bumpy, so this is necessary to work hard from the carriage." ”

"Carriage?"

Regarding Huang Fei's doubts, Gongsun Du did not explain directly, but said: "Think about our carriage." ”

"Carriage?"

Huang Fei's eyes lit up and said, "Your Majesty means to increase the spring?" ”

"That's right, but it's going to be shock absorption." Gongsun Du said at this time, "However, when you do it, you must take into account the difference in the size of the carriage and the train carriage, otherwise there is likely to be an accident." ”

"Well, the concubine knows, and she will remind everyone to pay attention." Huang Fei nodded.

After speaking, Huang Fei simply took out a pen and paper from the small bag he carried with him and began to write and draw, and Gongsun Du saw this and had an idea in his mind - "There is a girlfriend of a top student, how to break it?" Urgent, online, etc.! ”
