Listening to the number, there were at least forty or fifty horses.

If it's just the sound of horses' hooves, everyone naturally won't care, after all, there are so many bigwigs in Chang'an City, and there are people who are qualified to bring dozens of younger brothers when they come out.

In fact, if it wasn't for the emperor to go on a winter hunt this time, there was an absolute guarantee of safety, and if those princes went out on a long trip, which one wouldn't bring a few hundred people? If the eldest grandson Wuji and the others go out, dozens of guards and more than a dozen maids around him are also necessary.

It's not the number of people who care, it's the sound of horses' hooves itself!

Crisp and loud!

The sound of ordinary horses' hooves is trampling, although it sounds heavy, but it also seems quite dull, but the sound of horses' hooves at this time is a sound that is worthwhile, not at all like the sound of horses' hooves, but like ......

"Horseshoe! It's the sound of a horseshoe! ”

The well-informed among the magnates who had already arrived quickly recognized the voice, and at the same time exclaimed, "So many horses are all equipped with horseshoes? You can't just have money...... Hey? Who is this? ”

After seeing the appearance of the person at the head, several people were stunned at the same time.

Who's this?

When the comer and the fifty guards behind him slowly stopped, and the slightly immature face was displayed in front of more people, many people were still confused, and they didn't know the identity of this person at all - with fifty guards, according to the rules of this winter hunt, this young man must be the prince of the dynasty, but there are only a few princes who stay in Chang'an, why is this face so unfamiliar?

There was also Li You, the king of Qi, who squeezed his eyes vigorously, but he couldn't recognize which one this was!

And......

"Damn, why did he get all the guards horses on horseshoes?"

After taking a closer look, Li You quickly gritted his teeth - since the emperor discovered the huge effect of the horseshoe, he immediately recruited blacksmiths to make horseshoes for the war horses, and no one else was allowed to make them privately!

There are too many alien races in Chang'an City, once it spreads, don't think about keeping it secret.

Therefore, even if the reason is a prince, Li You can only put horseshoes on a few of his favorite horses, and as for the other horses in the palace, I am afraid that they can only be turned after most of the war horses of the armies are loaded.

And this guy in front of him obviously stimulated Li You.

This kid was originally a master who was not afraid of heaven and earth, and as soon as his brain was hot, he rushed over directly: "Phew! Who's coming? ”

"Uh......"

The war horse that had just controlled the crotch stopped, Li Yuanjia was grinning because of the burning sensation on the inner thigh, and he was stunned after listening to Li You's big drink! What's the situation?!

Who is this kid? What do you want to do?

Li Youke would not stop waiting because of his dazedness, and soon whipped his finger and continued to shout: "Bold! Why don't you answer this king's question? Also, Your Majesty has already decreed that you are not allowed to build horseshoes at will except in the army, who are you to be so bold? ”

“……”

The corners of his mouth twitched, and Li Yuanjia was completely speechless.

Of course he knew about the emperor's order not to make horseshoes at will, and he knew the details very well.

In fact......

Strictly speaking, this order was proposed by him!

At the beginning, Li Shimin didn't attach so much importance to the horse's shoe, because on the one hand, it was indeed a bit unbelievable to put shoes on horses, and on the other hand, the low production of Datang pig iron also made Li Shimin a little distressed.

According to the practice of Han Wangfu, a horseshoe is at least half a catty, and if all four hooves of a horse are loaded, it will cost two catties of iron! So for a simple calculation problem, if you want to load all 10,000 war horses with horseshoes, you need at least 20,000 catties of iron! Considering that there will inevitably be losses in the middle, it may take 22,000 catties to 25,000 catties in the end!

This cost is really scary!

How many horses are there in total?

Let's not talk about the Tang Army, even if it is a civilian, there are still hundreds of thousands of horses after all, right?

Wouldn't it cost millions of catties to nail all the horseshoes?

Don't doubt this, you must know that Datang's horses are expensive, and an ordinary horse will cost at least twenty or thirty times, and if it is a good horse, it is not uncommon to have hundreds or even thousands of times. After all, there are many horse lovers in Datang, and some are willing to spend a lot of money for a good horse.

Even if it is an ordinary horse, it costs twenty or thirty times, which is very valuable.

Nailing four horseshoes can extend the life of a horse a lot, and who doesn't know if this is a good deal? So it is conceivable that once the horseshoe spreads, I am afraid that all the horses in the world will soon be nailed to this thing!

If Datang can produce so much iron every year, and it is used to beat horseshoe, what should be done with the weapons and armor in the army? What about the tools that farmers need?

So after thinking about it a little, you will know that this matter can only be done slowly, and it must not be let go all at once!

Spend decades...... It will take at least ten years to equip Datang's horses with horseshoes, which may not affect the demand for pig iron in other aspects.

And if the reason is to say, one secret in the army is enough!

As for saying that the aliens know about the horseshoe, will it really pose a threat to Datang......

Hehe, it's not that Li Yuanjia looks down on those barbarians, just take the Tibetan and Western Turks in these years, if they really dare to put a horseshoe on all the war horses, Li Yuanjia will definitely do his best to persuade the emperor and meet the needs of customers with the greatest enthusiasm!

Ask the blacksmith for the blacksmith, and the iron for the iron!

If you don't earn back the last pair of bottoms of these barbarians, Li Yuanjia will hang on the beam of his big house!

Well, that's a long way off.

Anyway, after listening to the arrogant words of the kid in front of him, Li Yuanjia raised his eyebrows and chuckled: "This king? Are you Li You? ”

There are only a few princes and county kings of the Tang Dynasty, and almost all of Li Yuanjia's contemporaries have been released, and he also knows those who stayed in the capital. So although we haven't met much in the past few years, since the other party dares to call himself the king, it must be Li Shimin's son.

Looking at the age of the other party again, it is either Li You or Li Su, and he is so arrogant when he stays in the capital......

Big nephew, it's you!

Hearing the other party call his name, Li You was angry and shocked.

The anger is that even the ministers in the court have to call him a king when they see him, except for the emperor and the crown prince, no one has dared to call him by his name for a long time; And the surprise is that since the other party dares to call it so, and the appearance is such a big battle, I am afraid that the identity is not ordinary......

Just when Li You raised his eyebrows and was about to ask who the other party was, a person suddenly rode his horse, and when he was still more than ten steps away, he laughed and said: "Haha, king, you arrived a little late today!" ”
