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

It was only after Liu Tan finished speaking that he reacted slowly, where did the horseshoes come from in the age when there were no harnesses!

However, he could ignore others, but he couldn't ignore Liu Che's question. He would definitely be beaten violently.

So Liu Tan sorted out his thoughts and said: "The horseshoe is an idea of ​​Erchen. I have already thought about it when I was building the cement road, but it has not been made into a finished product, so I didn't tell my father."

Liu Che nodded and didn't ask any more questions. Anyway, no matter how much you ask now, it's better to see the finished product when the time comes, so he said, "It's getting late, let's go have dinner."

So the group moved to the main hall again.

After sitting down in the main hall, everyone who originally wanted to discuss the harness was instantly attracted by a special smell.

After Liu Tan's three dishes shocked Liu Che and Chen Ajiao's sense of sight and taste, they shocked these generals again.

Sitting at the top, Liu Che smiled complacently when he heard everyone's praise, as if he was the one who praised him.

But Liu Tan has some headaches. He has just invented stirrups and saddles, and now he is making horseshoes. Isn't the speed of this invention a little too fast?

No matter how talented a person is, it takes a little accumulation to invent things, and inspiration doesn't come just by saying it.

Will he be caught as a monster for doing things so quickly?

The only good thing now is that the horseshoe and the harness are a complete set, even if he made them all, it would not be too strange, and there is the cement road as a reason.

But for the rest, just... Forget it, don't make too much at once, or he will be watched by crowds.

Even if the horseshoe turmoil, or the concrete road turmoil had passed, Liu Tan hurriedly asked the people below to serve food.

Originally, everyone was still discussing about the harness, but when the boiled vegetables were served, everyone was attracted by this novel performance.

The moment when the flowers bloom always reminds people of many beautiful words, even the dishes. Such dishes can be regarded as works of art.

The military commanders didn't know what words to use to describe this dish. The only thing they had in common was that they couldn't bear to destroy the beauty.

Instead, Liu Che directly set down his chopsticks, and all the ministers followed suit after seeing him set down their chopsticks.

At first, everyone thought that this dish was just good-looking, but when the boiled cabbage entered the mouth, the freshness of the vegetables and the fragrance of the thick soup captured everyone's taste buds in an instant.

For a moment, the originally lively hall fell silent, and everyone was immersed in the joy brought by the delicious food.

Just when Liu Tan had just eaten two vegetable leaves, he looked up and found that Gongsun He on the opposite side had already finished his soup.

Liu Tan was dumbfounded, and Gongsun He smacked his lips after drinking and said, "It tastes good, but it's a little short. How can a vegetable be enough?"

You really don't see the outside world!

Liu Tan said with difficulty: "This dish is...for an appetizer."

Gongsun He rubbed his belly and thought for a while before laughing: "Appetizers, that's quite appropriate, I'll open my stomach now."

The others agreed one after another, and Liu Tan was stunned. The general's stomach...is it that big?

Just at this time, the sweet and sour pork ribs are served.

This time, due to the large number of people, the smell of sweet and sour wafted throughout the hall. Liu Tan saw several people smelling the smell and began to salivate.

I don't really know that sweet and sour pork ribs are delicious, but the taste of sweet and sour can stimulate the secretion of body fluid.

Sweet and sour pork ribs are obviously more suitable for military generals than boiled cabbage, and military generals still like meat dishes more.

Liu Tan looked at how they were eating, and was very glad that he ordered to prepare a little more for each serving, otherwise... probably there would not be enough for these people to stuff their teeth!

He finally found out that Liu Che had been wronged before. How could Liu Che eat a lot? Compared with these generals, he ate too little.

Thinking about it this way, he couldn't help but recall that when Lu Xuan was entertained, the amount of food was given according to his appetite. Lu Xuan...couldn't be full?

After all, when he was growing up, Lu Xuan could barely be considered a general, and he was still a minority who had always been accustomed to eating meat. Thinking about it this way, Lu Xuan didn't even protest, which was really giving him face.

After drinking and eating, Liu Che took his generals back. Before leaving, Liu Che said, "Don't forget to show me the horseshoe you mentioned."

As soon as Liu Tan heard it, he knew that Liu Che was warning him to show Liu Che the next time he came up with something new.

Liu Tan had no choice but to resort to the universal sentence pattern: "Next time will definitely be sure!"

The generals also left contentedly, and their initial impression of His Royal Highness probably was that there were fresh toys and special dishes.

Li Ling was even a little bit reluctant, and wanted to chat with Liu Tan for a while.

However, Liu Tan guessed that he would prefer to stay for dinner. Of course, there is no way to do this. The lunch is so greasy. At night, Liu Tan only wants to eat porridge and side dishes. This is definitely not suitable for entertaining guests, so... You better go.

Of course, the most important thing is that Liu Tan has found a new thing to do for himself-making horseshoes.

In fact, the horseshoe itself is not difficult. As long as Liu Tan gives it a shape, the blacksmith can make it in a short time. Basically, half a day is enough.

The problem is the installation of the horseshoe.

At first, Liu Tan thought that it would be enough to nail the horseshoe on the horseshoe with a nail, so he specially found a mule to test it.

It turned out that after nailing it, it was really good at first, but within two days, the horseshoe fell off the sole of the mule's foot. At this time, Liu Tan realized that no matter whether it is a mule or a horse, the front part of the sole of the foot is full of horny, basically It is equivalent to human nails, and the nails are easy to fall off if they are moved for a long time.

Then other means of fixing are needed.

Liu Tan felt a little troubled for a while, and it was too hard for him. He did other things because he had seen the finished product. As for the horseshoe...he had only seen it on the horseshoe, and he didn't know how it was fixed.

So Liu Tan squatted in his study with a horseshoe in his arms and began to study it. Oh, while studying, he also asked a carpenter to make a model for him according to the shape of a horseshoe.

Not to mention that the carpenter under him was really ingenious, and he actually restored the shape of the horse's hoof and even the shape of half of the leg bone.

Therefore, every time Liu Tan sees the skeleton of a horseshoe on his desk, he feels in a daze as if he is a medical student.

After Liu Tan looked at the horseshoe in his hand several times, the only thing he thought of was to fix the horseshoe to the horseshoe with screws.

But now... there is no such thing as a screw.

Of course, he can indeed make it out and let his blacksmiths do it.

In fact, the craftsmanship of blacksmiths these days is actually very good, even if they make very fine objects, there is no problem at all.

At least that's what Liu said about his blacksmiths.

But Liu Tan still has another problem to consider—promotion.

Horseshoes are not just for the pavement of a horse.

It is true that the cement road is hard, but isn't the stone road hard?In some places, there are stone roads, don't horses run on them?

For horses, horseshoes can extend their service life, especially for draft horses used for transportation.

Compared with war horses, draft horses are used for a longer period of time, and the wear and tear of horseshoes will be greater.

If it is to be promoted, the cost of horseshoes must be low, otherwise, with the current wealth of the big man, it may not be able to be promoted by the entire army.

Screws need to be made by skilled blacksmiths, so the output is bound to be very low. If the consumption is not large, it can indeed be done in this way.

Liu Tan was in a difficult situation for a while.

If you don't use screws, then use elbow nails. After nailing the nails in, use the elbows of the nails to fasten them inside. This can fix it, but it's hard to say how long it can be fixed.

However, Liu Tan wanted to use screws. The benefits of screws are obvious. The most important thing is that the cuticle on the horseshoe will keep growing. After the screw goes in, it will become stronger and stronger as the cuticle grows. Basically, it can stay on forever. Inside, it will also become stronger and stronger.

Of course, the most important point is that the Huns can imitate the elbow nails, but can they also imitate the screws?

Yes, Liu Tan has not been particularly active in promoting harnesses because he was worried that the Xiongnu would imitate them.

The Xiongnu's iron smelting technology is not high, but as far as Liu Tan knows, even though the big Han banned merchants from selling iron to the grassland, some people still took risks to sell it.

These businessmen basically have homes and no country, oh, maybe they don't even care about their homes, otherwise how could they take such a big risk for money?

You must know that if you transport ironware and grain privately, if you are found out, you will be punished as a crime of treason.

In order to make the Xiongnu invisible, in addition to listing the horseshoe as a controlled item, it is to monopolize the technology so that they cannot copy it.

So what if those merchants could secretly create the shape of a horseshoe?How much money will the Xiongnu consume if it cannot be fixed for a long time?

If this is the case, Liu Tan even welcomes the Xiongnu to keep buying horseshoes. With their large number of horses, maybe a small horseshoe can drag the Huns down.

Of course, this was just his idea. In the end, Liu Tan decided to ask his father, oh, he could also ask his brother.

Anyway, he had people make bent nails and screws, and then made a cross-section of a wooden horseshoe, ready to demonstrate the difference between these two things on the spot.

Whether it is Liu Che or Liu Shi, they must have a clearer grasp of the general situation than Liu Tan. The most important thing is that they have a whole set of staff under them, who can brainstorm ideas.

And Liu Tan... because he has not yet been crowned king, he has no staff or anything, so he decided not to continue fighting with these two things!Liu Tan returned to the palace in a hurry, first went to meet Chen Ajiao, but found that Chen Ajiao didn't seem happy, even if Princess Danyang acted like a baby, she couldn't make her raise her eyebrows. What's the problem?"

Chen Ajiao said in a bleak tone, "Your Majesty has already set a date."

Liu Tan was taken aback for a moment, and was about to ask what date, but found that Princess Danyang no longer had a smile on her face, and immediately understood that a date for marriage was set.
