The autumn breeze blows, rolling up yellow dust all over the sky.

On the command platform, Li Qinzai tortured them, and the monarchs and ministers were stunned.

If a piece of iron is nailed to the horse's hooves, will the hooves of the war horse still wear out?

Such a simple logic, everyone understands it, and it seems to be a very easy trick to think of, but why has no one thought of it for thousands of years?

On the stage, Li Zhi and Empress Wu looked stunned, and after Li Tao and the veterans were stunned for a short time, their breathing gradually became heavier, their faces turned red, and their expressions gradually became excited.

They are all generals of a hundred battles, and they are naturally more familiar with the army and the war horses than the Son of Heaven.

"On the horse's hoof...... Nail a piece of iron? Li Tao asked in a trembling tone.

Li Qinzai had already seen everyone's expressions in his eyes, and when he saw the excitement on everyone's faces, the stone in his heart finally fell to the ground.

It seems that the Tang Dynasty should not have invented the horseshoe yet, otherwise this group of old killers would not have such expressions.

It's okay, it's okay, it's not ugly.

The atmosphere on the stage was very strange, Li Qinzai felt like a powder keg about to explode, although he didn't understand why the horseshoe made them so excited, but Li Qinzai was still afraid that this powder keg would suddenly explode.

So Li Qinzai said cautiously: "Yes, nailing an iron piece can solve the problem of horse hoof wear, and the iron piece is not difficult to make, and a blacksmith with a little skill can get it out......"

Su Dingfang said in a deep voice: "Little baby, before the Son of Heaven drives, don't you dare to talk nonsense, are you sure that after nailing the iron piece, the horse's hooves will not wear out?" ”

Li Qinzai said firmly: "The boy is willing to make a military order, if the horse's hooves are still worn, the boy is willing to apologize with his head." ”

He was sure of this, because it had been confirmed thousands of years later.

If you are sure, you might as well be arrogant and speak a little fuller, so as to highlight your superior image.

Although he is not interested in imperial power, if he can leave a good impression in front of the Son of Heaven, it is not a bad thing for him to live a life of eating and waiting for death in the future, and Jian can save a lot of trivial troubles in the emperor's heart.

I wanted to use Xue Ne's head to make a military order, but Xue Ne's father Xue Rengui was also at the scene, and it seemed a little rude......

In the crowd, Li Tao carefully studied Li Qinzai's expression, and seeing that he was confident, Li Tao frowned, and quickly glanced at the faces of Li Zhi and Empress Wu.

Then Li Tao stood up, brushed his beard and said in a deep voice: "The shaft is formless!" To serve the monarch, you can only rely on a loyal and brave heart, you don't have to swear by the head of the item, right or wrong, lead a horse out to try to know the truth. ”

Everyone grinned.

clearly reprimanded his grandson, but in fact, he had already exonerated him, and the old man still loved his grandson after all.

Li Zhi also smiled, and after glancing at Empress Wu, he said with a smile: "What the old general said is very true, Li Qinzai offers advice for the country, there is no need to talk about the head of the item, I am not a tyrant, I can't kill a loyal minister who serves the society." ”

"Deliver the order, bring a horse from the school grounds, and summon two blacksmiths from the ordnance superintendent, and listen to the front of the stage."

The eunuch hurriedly sent the decree.

Not long after, a rather ordinary war horse was led to the front of the stage, and there were ready-made blacksmiths in the Beida camp, and two blacksmiths also brought a group of apprentices, carrying iron furnaces, hammers and other iron-striking tools.

The next thing is simple.

Li Qin ordered the horse's legs to be raised, roughly measured the length and width of the horse's shoe, and then drew a drawing of the horseshoe for the blacksmith.

The blacksmith understood it at a glance, and immediately began to make a fire to cast iron, and then clanged and struck.

Soon the four horseshoes were built, quenched and cooled, and sent to Li Qinzai.

The horseshoe was sent to Li Zhi and Empress Wu, and the husband and wife looked at it carefully for a long time, and their faces became more and more strange and complicated.

Such a simple thing can solve the age-old problem of horse's hoof wear.

The wisdom of the predecessors was afraid that Mo also had a time when the light was dark, and no one thought of it for thousands of years.

Under the command of Li Qinzai, several soldiers raised the horse's legs and asked the blacksmith to nail the horse's hooves.

After a jingle for a while, the four horseshoes were firmly nailed to the horseshoe.

The horse neighed in dissatisfaction, then shook its head incessantly, and its four legs were rather uncoordinated as it stride, as if he was not used to his new shoes.

However, the war horse only adapted to a moment, and then gradually got used to it, the trotting was no different from usual, the rhythm and pace were normal, and the difference from ordinary war horses was that after nailing the horseshoe, the sound of the horse's hooves landing was different, and there was an obvious metal percussion texture.

Jun Chen watched this scene quietly, his eyes lit up, and the crowd gradually became restless.

Li Qinzai was not surprised, seeing that the war horse had already run very happily, so he saluted Li Zhi and said: "Your Majesty, why don't you order the soldiers to take some gravel and sand, let the war horse step on the gravel, and see how the effect is." ”

Li Zhi nodded again and again: "Quasi-play." ”

There were more than 20,000 soldiers on the school grounds, and the gravel was quickly taken, and it didn't take long to pave a gravel road in the middle of the school field.

A knight rode the horse and drove it ten times back and forth from the gravel road.

Dismounting, looking at the horse's hooves, he found that it was unscathed, the horseshoe was firmly nailed to the horse's paw, and the horse ran back and forth ten times from the sharp gravel without hurting the horse's hooves.

The monarch gasped, and then everyone looked ecstatic.

Liang Jianfang was quite obscene to an old man, but at this moment, his eyes were red, and tears were rolling in his eyes.

Su Dingfang clenched his fists hard, released them, and clenched them again, obviously in a very uncalm mood.

Li Tao forced himself to calm his beard, but his trembling hands betrayed his mood deeply.

Seeing this, he suddenly beat his chest with his fist, and looked up to the sky and sighed: "If this thing had appeared twenty years earlier, my Tang Dynasty would have already conquered the world, what Goguryeo, Baekje, what Tubo, Tuguhun, and where the horseshoe stepped on, they were all Tang soil!" ”

Li Zhi's mood was also extremely agitated, he pursed his lips tightly, and his eyes were fixed on the war horse with a horseshoe.

After a long time, Li Zhi suddenly said: "Old general, what is the current military horse of Datang, and what is the annual loss?" ”

Li Tao lowered his head and said: "Your Majesty, since Zhenguan, the first emperor Taizong has set up eight squares and forty-eight prisons in Longyou, and set up eight squares and forty-eight prisons for thousands of miles, and in the first year of Longshuo, the Tang Dynasty counted nearly 700,000 young horses and horses, and nearly 300,000 military horses were available. ”

In addition to nearly 10,000 horses dying of disease and starvation every year, the biggest loss is that the hooves of the horses are worn out and abandoned, and the number has reached nearly 30,000 every year."

"Every horse can go into battle at the age of three, but after a maximum of three or four years, it will have to be withdrawn from the battlefield because the horse's hooves have worn out and injured, and it can no longer be used."

"The lifespan of a horse is usually twenty years, but it can only be used for three or four years on the battlefield, and the huge loss is really regrettable, and it is also a great loss for my Tang Dynasty."

After Li Tao finished speaking, he glanced at Li Qinzai deeply, his eyes were indescribably complicated, and he couldn't tell whether it was pride or sentimentality.

Li Zhi also looked at Li Qinzai deeply, and said: "If the horseshoe made by Li Qing is promoted in the army, the old general, what will happen in the future?" ”

Li Tao was stunned, and suddenly said excitedly: "If this is the case, in the future, my Tang cavalry will be invincible in the world, and wherever the horse's hooves are tread, they are all Tang soil!" ”

One sentence seemed to ignite the long-suppressed emotions of the veterans, and with a bang, the veterans put on their armor and bowed: "Where the horseshoe is stepped, it is all Tang soil!" Datang Wansheng! ”

Xue Rengui said loudly with tears in his eyes: "Your Majesty, the minister is willing to ask for merit for Li Qinzai on behalf of the Tang Dynasty soldiers, a horseshoe can add tens of thousands of horses to the Tang Dynasty, and the Tang cavalry will no longer have to worry about the future, this great achievement can go down in history!" ”
