Zhao Huan looked at the landing flying boat, this flying boat was not even painted, so the original wood color was placed here.

Zhao Huan can also see the pedals inside the first layer, with a total of eight positions.

Unlike Zhao Huan's pursuit of comfort, this car does not have so many luxurious accessories and exquisite patterns.

Although it is a little rustic, it is practical and tight.

The power compartment on the lowest floor is very low, and people have to bend down to get in, just enough to sit down.

The second layer above is sealed, Zhao Huan can't see it from the outside, and the top layer has a fence, and the goods can be bundled in the open air.

The entire flying boat was less than three meters high, not very large, like a rectangular shuttle, lying prone on the ground.

The same track of the car was done by Qin Shi Huang, and the distance between the wheels was about six feet.

"Why not paint?" Zhao Huan looked at the land flying car and asked.

"If you paint it red, it's too expensive..."Li Gang scratched his head and said.

Zhao Huan was silent, this is the fourth year of the Great Song Dynasty's war, from the seventh year of Xuanhe to the third year of Jingkang, even the rich Great Song Dynasty can't afford to fight?

Li Gang saw that the official's face was full of worry, and said with a smile: "There are also well-painted cars, but the smell is very strong, so I didn't show them to the official." ”

Zhao Huan pondered for a while and understood why Li Gang had put a log cart to show him!

In fact, Li Gang's meaning is very simple, just two words! Hit the money!

This is crying poor!

Routines, Li Dazai, you're not honest anymore.

Zhao Huan walked up the escalator with a smile, personally got under the car and pedaled twice, tried it, but didn't pedal.

"If the horse is running, can the speed of the horse's pedaling keep up with the speed of the horse? Won't it hurt your feet? Zhao Huan raised his own question.

Then I saw Li Gang's extremely skeptical eyes.

Li Gang took out a wheel and said, "I thought the officials would ask some other questions." ”

"This is a flywheel, a simple application of the official's mechanical principle. When you press forward hard, the chain drives the flywheel to rotate forward. ”

"At this time, the flywheel internal teeth and the jack contain each other, naturally you can move forward, when you don't use force, the flywheel jack all bite the internal teeth, naturally it will not drive the chain, how can it hurt the boatman?"

Li Gang's face was full of doubts, Zhao Huan looked at the power cabin under his feet and watched the flywheel for a long time.

Only then did he understand that this land flying boat was, to put it bluntly, a bicycle running on railroad tracks!

Li Gang is so mysterious!

In the final analysis, it is still relied on horse-pulled, and the role of people in the car is to help.

Zhao Huan suddenly understood what Li Gang had done.

I also understood what Li Gang's eyes meant.

His question is like asking whether people will be injured by stirrups if they don't pedal when they are riding a bicycle......

In this way, it is indeed very stupid.

Zhao Huan got out of this three-meter-long car, which is indeed a very interesting invention.

Horsepower man-assisted self-propelled rail car?

"How fast can this land boat fly?" He looked at the position of the pull ring and carefully monitored it, and the reason why it was only made more than two meters high was mainly because he was afraid of rolling over.

Li Gang bowed his head and said: "Traveling thousands of miles a day, it's not a problem, but you have to change horses at every stop, there are not many horses in the Great Song Dynasty, so there are not many land flying boats." ”

"Those eight people pedaled in the car, all for the sake of saving horsepower."

Zhao Huan took a deep breath, there was no horse!

Since I came to the Great Song Dynasty, this topic has been hovering in my mind and has never been far away.

The current grassland inferior horses are only enough for the army of the Great Song Dynasty, and this is a gallop for transporting grain and grass, and the priority is not as high as that of the military.

"Sun Yi is in Datong's horse farm, hasn't he been out yet? Isn't it known as a million-dollar military horse farm? Zhao Huan continued to walk forward and asked.

Li Gang nodded and said: "Sun Yi and Mr. Yang's horse circle has just been done for less than two years, where is it so fast?" ”

"What is this?" Zhao Huan looked at the car in front of him and asked with curiosity on his face.

At the starting point of this Yellow River crossing, there are not only land flying boats and Zhao Huan's big drivers, but also a small car that is not very high.

It is one meter high, less than two meters long, and about six feet wide.

Li Gang sighed and said: "I haven't come up with a name yet, but I think it's too laborious now, and I don't know how to change it." I made a sample. ”

"This year, Guangbei Siege has been doing the training of land flying boats, and the result is made, there is no horse, the fastest galloping iron and wood rail road, can only be done like this, everyone is a little anxious, just thinking about using manpower."

"You can sit two people in the middle, and you can step on it like a land flyboat, but it takes up a lot of space to sit in it. I can't put much of it. ”

Zhao Huan nodded, he knew what Li Gang wanted!

The Great Song Dynasty lacks horses, this is a fact, Shangjing Road has just been recovered for less than a year, not to mention feeding the Central Plains, and even self-sufficiency is still struggling.

If there is a shortage of horses, we must find a way to replace the power, and Li Gang's idea is to replace horsepower with manpower.

On the land flying boat, Li Gang's idea of improvement can already be seen.

What he wants to do now is a small rickshaw that can run on the rails, and use the repaired iron-clad wooden tracks first.

"Bring the pen!" Zhao Huan shouted!

Just now, I was fooled by Li Gang's mysterious name and strange design, and now it's the part he's good at!

Zhao Ying heard Zhao Huan's call, followed another little eunuch and ran away, and after a while, he carried a table with a pen in his hair and ran back.

Zhao Ying pulled the pen from the tip of her hair and said, "Here, the official family, it's not a sheep's hair, if the official family is not used to it, I'll look for it." ”

Zhao Huan looked at Zhao Ying, who was panting, and said, "I can use it if I don't need it." ”

Zhao Huan drew a three-dimensional view on the paper, and then drew a few more pictures, looked at the little eunuch next to him and asked, "What's your name, I've always seen you in the past two days." ”

The little eunuch didn't seem to have reacted yet, and when he heard Zhao Huan's question, he hurriedly said, "Chen Xiaohuangmen Sun Li." ”

The little yellow door looks like it has this small character, but it is not low in the rank of the inner palace.

And being able to be taken by Zhao Ying to his side and be taught face-to-face, I think he is a clever person.

Just like just now, Zhao Huan wanted to pretend to be forced...

No, Zhao Huan wanted to paint, and Sun Li did a good job, suppressing the corners of the paper that were blown up by the wind.

Zhao Huan took the paper and pointed to the picture and said: "Human-powered rail car, you can call him a hand-rolled car, which can be designed for two people or set up for four people." ”

"Using the principle of levers, the oblique shaft is driven, and the oblique shaft drives the crankshaft, with a weight of less than two hundred catties, and it can carry three or four hundred catties of goods."

"Perfectly suited to your requirements, no horsepower, just manpower, and pretty fast. It can run 80 miles in about an hour, the speed is not fast, and the pull is not much, but it is simple to manufacture. ”

Li Gang looked at this picture for a long time, bowed his head and said: "The official is wise, this has solved a big problem." ”

Zhao Huan knew that the human-powered rail car would be eliminated in the end, and said with a smile: "Where is the big problem, it's just a small problem." ”

"When a few horse farms come out, the land flying boat is estimated to be the main force of freight, and my two-person car is still too small."

Li Gang carefully put away the words drawn by the official family and said, "The official family, I don't know anything." This gallop is not less expensive. ”

"Especially this iron-clad wooden track, seven thousand guan in one mile is not enough, Yan Bian Chi Dao, it took nearly seven million guan!"

"Not counting the cost of each station, and the replacement of all rails in the future, that's a lot of money."

"In fact, there is a lot of pressure to prepare for the siege, and this road has been repaired, but it can't be used for a long time, and there is nothing to use! How many people are waiting to catch the pigtails of the workers' relief home, so that they can participate in a book. ”

When Zhao Huan heard this, his face changed abruptly, and he said loudly: "I see who dares him!" ”

Zhao Huan is the most annoying kind of person, he will stand up to the best national politics when he has nothing to do, and desperately look for shortcomings!

I can't wait to become Hu Yuan and take this magnifying glass to look at people all day long!

"Don't give time, don't give opportunities, don't look at everything, and even get entangled in groups, and turn this kind of national politics that benefits the country and the people to death."

"What is their purpose? Very simple! When the imperial court had no money to build roads, when they bought these roads, they took them themselves! ”

"That's for the court? That's the profit of gluttonous Jinqiao Silver Road! ”

"Cheap!"

Zhao Huan's anger was very great, Zhao Ying and Sun Li instantly lay on the ground, and they didn't dare to gasp.

When the official family killed more than 100 ministers in the Wende Palace, they were not so angry.

Even Li Gang lowered his head and didn't dare to speak, he originally only wanted to complain about the difficulty of state affairs, but he didn't expect to provoke such a big anger from the official family.

Of course, Li Gang has the right to complain, as Zhao Huan's accession to the throne, Zhao Huan's number one minister!

He is still a sole minister, and he can't tell others these complaints, he can only say them to the emperor.

I didn't think of a small complaint, complaining that Guangbei Siege could not design a suitable product, and a few words of idle talk without ideas attracted such a big anger from the officials.

Zhao Huan was still angry, thought for a long time, and said: "Even if the horse runs on the gallop road, it is faster than the carriage!" Less effort than a horse-drawn carriage. ”

"One counts as one, and whoever talks needs to stop."

"Regardless of the court, the courtiers in the court will be fined for half a year for the first time! The second time, I will be thrown to Shangjing Road to plant pasture! Another time he was exiled to Lingnan. ”

"Nope! The second time, I was dismissed and thrown to Lingnan! It's the other way around! Eat the grain of the country, don't do anything for the country, and pull the hind legs, it's not too much! Zhao Ying wrote it down and became the norm! ”

Zhao Ying asked tremblingly: "The matter of the official family's abolition of the Dao, is it to be deposed or beheaded." ”

"What do you say?" Zhao Huan asked with a glare.

Zhao Ying didn't dare to ask again, so he remembered a beheading.

Li Gang also wiped the sweat from his head, he didn't dare to ask, and he also remembered that he had beheaded him......

After all, it's not too much to cut off the head, it's the official family, and the gentleman says that the horse is difficult to chase.

"Official, why are you so angry?" Li Gang looked left and right, and only asked if it was appropriate.

Zhu Lian had been paying attention to Zhao Huan here, and when he saw Zhao Huan so angry, he also walked over. Holding Zhao Huan, he said: "Official, don't be too angry, what happened, what to solve, angry and hurtful, Zhao Duzhi, go get some tea." ”

Sun Li got up and went to the car to get water.

Zhu Lian said with a smile: "Drink saliva, smooth air." Before the concubine set off, she burned some ginger brown sugar tea to warm her stomach. ”

Zhao Huan finally dissipated most of his anger, and this anger was indeed a little unreasonable.

He looked at Li Gang and asked, "Li Dazai, what do you say is this under our feet?" ”

Li Gang stomped his feet and said, "Official, under our feet is the Great Song Dynasty!" ”

Zhao Huan nodded, Li Gang's answer was a standard answer, but what he said was not this.

He stepped on the gravel under his feet and said, "There is ballast under our feet." ”

"Then Li Dazai, what is the use of this ballast?" Zhao Huan asked with a smile.

Ballast is the layer of pebbles under the ironwood tracks.

Zhu Lian also looked at Li Gang curiously, it was the first time she heard the monarch and the minister play right, obviously this is not a national policy, she can listen to it.

Li Gang was stunned and said: "Drainage, shock absorption, this summer heavy rain, where can the water be drained without this layer of ballast?" Each of these land flying boats is 500 catties, plus the goods, without this layer of stones, it would have been pressed down long ago. ”

"And one more clever use! Lee Dazai. Zhao Huan said with a smile.
