Zhao Huan looked at the land flying boat. The flying boat was not even painted, and the color of the wood was placed here.

Zhao Huan can also see the pedals inside the first floor, with eight positions in total.

Unlike Zhao Huan's big-haired jade carriage, which pursues comfort, this car does not have so many luxurious accessories and exquisite patterns.

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

The power cabin on the bottom floor is very low and people have to bend over to get in and just sit down.

The second layer above is sealed, which Zhao Huan cannot see from the outside. The top layer is fenced, and the open air can bind goods.

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

The same track was done by Qin Shihuang, and the distance between the wheels was about six feet.

"Why not paint?" Zhao Huan asked as he looked at the land speed.

"It would be too expensive to paint it in bright red..." Li Gang scratched his head and said.

Zhao Huan was silent. This was the fourth year of the war in the Song Dynasty. From the seventh year of Xuanhe to the third year of Jingkang, can even the rich and powerful Song Dynasty be a little unable to afford it?

Li Gang looked worried when he saw the official's face, and said with a smile, "There are also cars with good colors, but the smell is very strong, so I didn't show it to the official."

Zhao Huan thought about it and understood why Li Gang put a log car to show him!

In fact, Li Gang’s meaning is very simple, just two words! Make money!

This is crying for poverty!

Routine, Lee Tae-jae, you are not honest anymore.

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

"If the horse is running, can the boatman pedal speed keep up with the horse's running speed? Will it not hurt his feet?" Zhao Huan asked his own question.

Then I saw Li Gang's extremely suspicious eyes.

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

"This is a flywheel, a simple application in the official mechanical principle. When you step forward with force, the chain drives the flywheel forward."

"At this time, the internal teeth of the flywheel and the thousand pounds are in contact with each other, so you can naturally move forward. When there is no force, the thousand pounds of the flywheel and all the internal teeth will be bitten, so it will naturally not drive the chain. How can it hurt the boatman?"

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

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

Li Gang is so mysterious!

After all, it’s up to horses to pull, and the role of people in the car is to help.

Zhao Huan immediately understood what Li Gang had made.

I also understood what Li Gang's eyes meant.

His question is like asking whether people will be injured by stirrups when they are riding a bicycle...

From this point of view, it is indeed very stupid.

Zhao Huan came out of this three-meter-long car, which was indeed an interesting invention.

Horse-powered man-help track car?

"How fast can this land flying boat fly?" He looked at the position of the pull ring and carefully monitored it. The reason why he built it was only more than two meters high was that he was afraid of overturning.

Li Gang bowed and said, "It's no problem to travel a thousand miles a day, but you have to change horses at every stop. There are not many horses in the Song Dynasty, so there are not many flying boats on land."

"Those eight people were pedaling in the car, just to save horsepower."

Zhao Huan took a deep breath, no horse!

Since I came to the Song Dynasty, this topic has been lingering on my forehead and has never been far away.

The current grasslands are only enough for the army of the Song Dynasty. This is obvious that it is a road for transporting food and grass. The priority is not as high as that of the military.

"Sun Yi is in Datong's horse farm, haven't he taken off his horse yet? Isn't he known as a million-distance horse farm?" Zhao Huan continued to walk forward and asked.

Li Gang nodded and said, "Sun Yi, the horse circle under General Yang has only been built for less than two years. How can it be so fast?"

"What is this?" Zhao Huan looked at the car in front of him and asked curiously.

At this Yellow River Ferry Station, there are not only land flying boats and Zhao Huan's big van, but also a small car that is not very tall.

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

Li Gang sighed and said, "I haven't named it yet. I just think it's too hard to do it now, and I don't know how to change it. I made a sample."

"This year, Guangbei City Siege has been training land flying boats, but it turned out that it was useless. The fastest iron-wood track road, which can only be left like this. Everyone was a little anxious and thought about using manpower."

"You can sit two people in the middle, and you can trample it like a land flying boat, but sitting in it like this really takes up space. You can't put much goods."

Zhao Huan nodded, he knew what Li Gang wanted!

The Song Dynasty lacked horses, which is a fact. Shangjing Road has just recovered for less than a year. Not to mention feeding back to the Central Plains, it is still difficult to even be self-sufficient.

If you lack a horse, you have to find a way to change the power. Li Gang's idea is to replace horsepower by manpower.

On the land flying boat, you can already see Li Gang's improvement idea.

What he wants to do now is a small human-powered cart that can run on the rails, and first use the repaired iron-clad wood track.

"Get a pen!" Zhao Huan shouted!

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

When Zhao Ying heard Zhao Huan's call, he followed another eunuch and ran away. After a while, he carried a table with a pen inserted into the end of his hair, and ran back.

Zhao Ying pulled the pen from the end of his hair and said, "Give it to the official family, it's not a sheep hair. If the official family is not used to it, I will look for it."

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

Zhao Huan drew a three-view on the paper, 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 these two days."

The little eunuch seemed to have not reacted yet. When he heard Zhao Huan's question, he hurriedly said, "My little Huangmen Sun Li."

The small yellow gate looks like this small character, but it is not low in the inner palace.

And if you can be brought by Zhao Ying by his side and give him an in-person instruction, I think he is a smart person.

For example, just now, Zhao Huan wanted to show off...

No, Zhao Huan wanted to draw, Sun Li did a good job, suppressing the corner of the paper that was blown by the wind.

Zhao Huan held the paper and pointed to the picture and said, "Human-powered rail car, you can ask him to hand-roll the car, it can be designed as two people or four people."

"Using the principle of leverage, the inclined shaft drives the crankshaft, and the weight is less than 200 kilograms, which can carry about 300 kilograms of goods."

"It meets your requirements perfectly. It does not require horsepower, it only requires manpower, and it runs quite fast. It can run eighty miles in an hour. The speed is not fast, and it does not pull much, but it is simple to make."

Li Gang looked at this picture for a long time, bowed and said, "The official is wise, this solves a big problem."

Zhao Huan knew that human-powered rail cars would be eliminated in the end, and said with a smile, "What is the big problem? It's just a small problem."

"When several horse farms take off, land flying boats are probably the main force of freight. My two-person car is still too small."

Li Gang carefully put away the official paintings and said, "The official family doesn't know anything. This Chidao costs a lot of money."

"Especially this iron-covered wooden track, a mile of 7,000 guan is not enough. Yanbian Chi Road spent nearly 7 million guan!"

"It's not about the expenses of each station, and the replacement of all rails in the future is a high number."

"In fact, Guangbei's siege is under great pressure. This road has been repaired, but it has been delayed and there is no use. There is nothing to use! Many people are waiting for the small braids in the labor and relief institute, so it is easy to learn from it."

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

Zhao Huan is most annoying to such people. He just faces the best national policy and tries to find shortcomings!

I wish I could transform into Hu Yuan and take this magnifying glass to see people all day long!

"If you don't give time, don't give chance, don't look at everything, you can even get entangled in groups, and turn this national policy that benefits the country and the people to death."

"What is their purpose? It's very simple! When the court has no money to build roads and buy these roads, they will take them away!"

"That's for the court? That's the profit of Jinqiao Yin Road!"

"Sincere!"

Zhao Huan was very angry. Zhao Ying and Sun Li instantly lay on the ground, not daring to breathe.

When the officials killed more than one hundred ministers in Wende Hall, they were not so angry.

Even Li Gang lowered his head and did not dare to speak. He turned out to be just a few words to complain about the difficulties of state affairs, but he did not expect to make the government so angry.

Of course, Li Gang has the right to complain. As Zhao Huan's number one minister after he ascended the throne!

He is still a solitary minister. He can't tell others these complaints, but he can only tell the emperor.

I didn't expect to complain that Guangbei's siege could not design products suitable for Chidao. A few casual conversations that had no idea attracted the anger of the government.

Zhao Huan was still angry and thought for a long time, and said, "Even if the horse is dragged and runs on the road, it is faster than the carriage! It is more energy-saving than the carriage."

"There is one counting one, who says that the road needs to stop."

"Not to mention outside the court, the court officials in the court will be fined half a year for the first time! The second time I will throw them to Shangjing Road to plant grass! I will be exiled to Lingnan once again."
