I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Tan stood up and asked, "Father, do you want to ride an ice cart or fish on ice?"

Liu Che waved his hands vigorously: "Come on!"

Liu Tan had no choice but to explain: "I don't have an ice car, I have to make it now, and it's not easy to master. I just watched people play it, and I don't know much about it."

Liu Che didn't care: "Then let someone do it."

All right, Liu Tan doesn't care, the ice cart is much easier to make than other things, he got up and said: "Then I will go to the carpenter and make two first."

Liu Che waved at him, Liu Tan turned and left, and Gun Gun would naturally follow him as soon as he left.

As a result, Gun Gun hadn't taken two steps before he felt the back of his neck being grabbed, and couldn't help crying out.

Liu Tan looked back and saw that Liu Che was pulling Gun Gun towards him, and said while pulling, "The iron-eating beast stays with me, you go."

Liu Tan took a sympathetic look at Gun Gun, and said to himself, Dad can't save you anymore, so please ask yourself!

Then he left without burden, Liu Che would not really hurt Gun Gun anyway, he raised it carefully after all.

Because he was in a hurry, Liu Tan didn't draw a picture, so he directly asked the carpenter to dictate.

After all, this thing is really simple. The simple version of the ice car may be a wooden board on the top, with skates on both sides below. When playing, people sit cross-legged on the wooden board.

But of course the things for Liu Che couldn't be so perfunctory, so he directly made the shape on the ice cart into a weighing scale with a semicircle.

Liu Tan looked at the sitting scale and hesitated for a moment, wanting to change it into a shorter chair.

How is this scale used?

Sitting squatting, frankly speaking, is kneeling.

Thanks to this body, I have long been used to this sitting posture, but it is also uncomfortable after a long time. Where is the chair comfortable?

It's just that the posture of sitting squatting is stipulated in the scope of etiquette, and Liu Tan has to change the etiquette if he wants to change it.

This kind of thing is too challenging and different from others, so he has never cared about it.

Now, it's better to let Liu Che get used to it in advance.

Liu Tan just did what he said, and asked the carpenter to increase the height of the sitting scale a lot, and by the way, he also added a place for feet in the front.

After the main body of the ice cart is made, the skates are put on it.

The ice skates were also made by the blacksmith. They were made according to the shape of the sharp ends in his memory, and they were directly installed on the ice cart.

Then there are the two most important ice rods of the ice cart. When a person sits on the ice cart, they rely on these two sticks on the ice to force the ice cart to slide. Iron made two.

These things are relatively easy to get, but Liu Tan always feels that something is missing.

He circled the ice cart, thought for a while, and ran to an oxbow lake with his people.

Fortunately, there are quite a few oxbow lakes near Shuofang City, otherwise it would be difficult to find such a place for a while.

Liu Tan originally wanted to go up to try, but was stopped by Wei Deng.

Although the ice layer on the lake was very thick, it was the first time to use the ice cart, and no one dared to let Liu Tan go up directly. For this reason, Wei Deng even went all out and planned to go up first.

After thinking about his own motor cells, Liu Tan agreed to let Wei Deng try it first.

After asking to understand the operation process, Wei Deng got on the ice trolley directly, tried to push it with the ice drill, and then found that the ice trolley was running smoothly, and then began to increase the strength little by little.

At the beginning, he was a bit restrained, but probably because the feeling of skating on the ice was so good, he gradually pushed harder, and he could slide for a long time with one poke. In addition, he poked fast and urgently, and then he felt like he was flying on the ice. .

Probably no one can refuse such an activity, except for the face being blown a little cold, it is too happy.

However, Wyden still remembered that he was helping to test the stability of the ice car, and after a while, he was ready to stop.

However, at this time he discovered one thing - he had so much fun just now that he couldn't stop now!

Wei Deng was a little flustered and shouted loudly: "Your Highness... I can't stop!"

Liu Tan slapped his forehead, and then remembered what he forgot - brake!

He watched Weiden circling on the lake and shouted: "You control the direction, don't use force, just wait for it to stop by itself."

Weiden:? ? ? ? ?

Wei Deng thought about how hard he was just trying to pursue in quick succession, and couldn't help shouting: "Then~ have to wait~ how long~ ah~"

Because the speed was too fast, the wind blowing in front of him literally changed the tone of his voice, and it was trembling, which sounded a bit miserable.

Liu Tan smiled unkindly: "I don't know! It's okay, it will stop sooner or later! Be careful yourself, I will take someone back to continue the transformation!"

After speaking, he took his own people and left, leaving only two people waiting for Weiden on the shore.

Wei Deng: "Your Highness!"

There was a howl of ghosts and wolves floating on the oxbow lake, which startled the crows around.

Liu Tan brought people back, because he was used to making things that often had problems, so he made a spare one when he was doing it this time.

As for the so-called brake system, it is actually easy to add a row of small skates in front of the car, but the shape of the skates is different from the one below, with a very sharp right angle.

Usually these small ice skates do not touch the ice surface, and they are considered to be in a half-cocked state. If you want to stop the ice cart, you can just stretch your feet and step on the front brake pedal, and the small ice skates will come into contact with the ice surface, increasing the speed. Resistance to make the ice car stop slowly.

Because I am worried that the ice car will easily turn over if it stops suddenly, this brake skate is done more gently.

Liu Tan returned to the oxbow lake with the newly completed ice cart, and Wei Deng was squatting on the edge of the oxbow lake at this time.

Liu Tan walked over and asked, "If you don't hurry back, what are you doing here?"

Wei Deng's face was pale: "I'm a little dizzy."

Liu Tan laughed and said, "It's what you deserve, for making you paddle so fast."

This oxbow lake was not small, but no matter how small it was, it would not allow Weiden to travel in a straight line, and the ice surface was not particularly smooth, so he had to keep turning to avoid those uneven places.

Wei Deng looked at Liu Tan sadly, Liu Tan thought for a while and said comfortingly: "You played the ice car very well for the first time, better than most people."

Wei Deng felt a lot of comfort in his heart, and then he saw Liu Tan pointing to another ice cart and said, "Try this."

Weiden:? ? ? ?

Seeing his unbelievable expression, Liu Tan quickly said, "This ice cart has brakes, which means it can stop. Look here? You can stop it after you step on it."

Wei Deng was dubious: "Really?"

Liu Tan looked serious: "When have I ever lied to someone? Go quickly."

Wei Deng had no choice but to try again, but this time he learned the lesson from last time and didn't dare to play so crazy again.

Liu Tan saw that the braking system of the ice car was not bad, at least Wei Deng's speed was fine. He thought about Liu Che, although he didn't know how high his father's strength was, but it should not be better than Wei Deng who had been training for several months. This level is about the same.

Liu Tan nodded in satisfaction and said, "Let's go, find another lake."

After this lake was "ruined" by Wei Deng, it was covered with all kinds of scratches. Although it is not impossible to play, since Liu Che wants to play, he must find a relatively clean one, and he also needs someone to treat the ice surface.

In fact, the terrain around Shuofang City has almost been explored. Liu Tan chose a lake on the map and said, "Go over and have a look, and clear all the reeds on it if you can."

After Liu Tan finished speaking, he led the people back, so he didn't have to go to clean the ice himself.

As a result, as soon as he walked halfway, the person he had just sent chased after him on horseback, and panting, he said, "His Royal Highness, that lake...it's not frozen!"

Liu Tan was stunned for a moment: "Is it not frozen?"

Impossible, at the current temperature in the northern border country, as long as it is not running water, the ice layer is not thick enough to be sorry for the bad weather. How can there be a lake that does not freeze?

But these knights probably wouldn't lie to him either.

Liu Tan suddenly had a flash of inspiration: "Is the water in the lake salty?"
