A few days later, after the first batch of horseshoe copper was manufactured, Yang Hao came to the racecourse again.

Nailing horseshoe is a technical job, as Yang Hao, who has lived in modern times for decades, for this almost lost craft, he has only seen it occasionally in some film and television works or when browsing the web.

Now he has to create a new craft from scratch, which is very challenging for him.

He spent several days preparing for this, studying in detail the structure of the horse's hooves and the techniques that might be involved in nailing the horseshoe.

People change new clothes, horses change new shoes!

If you want a horse to maintain a long lifespan, nailing a horseshoe is an essential step.

Yang Hao observed the horse's hooves and found that the horse's hooves are roughly divided into two layers, the bottom layer that is in contact with the ground is about two to three centimeters thick hard keratin, and the upper layer is the living keratin.

Knowing the structure of the horse's hooves, the next thing is easier.

Yang Hao designed a set of processes for Ma Dingzhang.

To put it simply, it can be divided into five steps.

The first step is to repair.

The so-called repair is to disassemble the old horseshoe, and then trim the new hard keratin, remove the excess and untidy parts, and then polish the edges to keep them flat.

The second step is quantity.

And this step is very troublesome for the Daqi tribe who is still in the Bronze Age, the horse's hooves are the same as human feet, there are big and small, and the use of inappropriate horseshoes will also cause great harm to the horse.

The best way is to compare the made horseshoe with the horse's hoof, and through continuous correction, make the most suitable horseshoes.

But bronze is not as malleable as iron, and even if Yang Hao wants to do it, he can't achieve it.

He could only use the method of casting a wide net, randomly extracting some of these war horses, measuring their hooves, and then casting them into batches to make horseshoes.

This method is somewhat similar to the shoes of later generations of humans in different sizes.

Choosing this method is also a choice made by Yang Hao in desperation.

The third step is to nail the horseshoe.

This step is the most critical step, when the horse's hooves are trimmed in the first step, a white line will be exposed at the horse's paw, which is the experimental data obtained by Yang Hao from the hooves of dead horses.

If you want not to hurt the war horse, the horseshoe must be nailed to the periphery of this white line, which is the same as human fingernails, and it must be very painful to accidentally cut the flesh when cutting the nails.

And the horse walks on four legs, and if you accidentally nail it wrong, then the horse is largely wasted.

The fourth step is polishing.

And polishing is not polishing the horse's hooves, but polishing the protruding copper nails, although not polishing affects the horse's walking, but when the horse lies down, accidentally pricked, it will invisibly increase the losses of the Great Qi army.

After all, in this era, a healthy war horse is also an extremely important strategic resource, and Yang Hao does not dare to be careless.

The last step is to check.

This step mainly depends on whether the horseshoe nail is secure, whether there is any abnormality in the horse's walking, and if there is, the horse's shoe must be removed quickly to avoid greater losses.

Making such a detailed plan shows how much Yang Hao attaches importance to the war horse.

The cavalrymen whose hooves of the bastic shoes and war horses were worn out, led their beloved horses, instinctively lined up, and patiently waited for Yang Hao to diagnose and treat their beloved horses.

In their eyes, Yang Hao is a combination of wizards and leaders, and he is an omnipotent existence.

As long as his own leader makes a move, his little problem of loving horses will definitely be solved.

When the first soldier followed Yang Hao's instructions, he led his beloved horse to the parallel bars-like equipment.

He stood aside and looked worriedly at the restless horses in the parallel bars.

Yang Hao didn't start his performance immediately, but said to Fuhe and several officers: "You must look carefully, you will have to do these things yourself in the future, as cavalry, the war horse is your second life." ”

When everyone heard this, they nodded solemnly and concentrated on Yang Hao's actions.

Yang Hao took a deep breath, walked to the side of the war horse, calmed down the restless war horse, and asked the others to help fix the horse to prevent it from moving.

Subsequently, Yang Hao used the rope binding technique he had figured out, slightly clumsy to pull up the left front leg of the war horse, and carefully tied it to the wooden frame.

Yang Hao was very nervous about doing this, and he was very afraid that his methods would be unfamiliar, which would anger the horses, and it was a terrible thing to startle the horses.

Yang Hao's two knives can be said to be doing this with his head pinned to his trouser belt.

But fortunately, this horse is very suitable for his performance.

Doing this step can be said to be extremely smooth.

Yang Hao secretly breathed a sigh of relief, and praised this docile horse in his heart.

In the eyes of everyone, Yang Hao carefully trimmed the horse's hooves according to the method he had formulated.

He did it very carefully, just a front hoof Yang Hao took nearly twenty minutes, such a long time, if he was a familiar hand, it was likely that he would have finished this horse long ago.

After carefully checking the flatness of the horse's hooves, and after feeling satisfied, he called everyone to his side.

"Seeing that there is no white thread in this circle, in the future, when you trim to this extent, don't repair it, that will hurt the horses."

Fu looked at the horse's hooves and said, "Chief, won't the horse hurt if you do this?" Why didn't I see this horse struggling? ”

Everyone also looked at Yang Hao with puzzled expressions.

Yang Hao said and smiled: "When you want your own nails, will it hurt?" ”

When everyone heard this, they were stunned.

"What do you mean, the chief, that the horse's hooves are the same as our fingernails?"

Fu asked.

Yang Hao nodded and said: "That's right, if you exceed this white line, you will hurt the flesh, you must remember, if you make a mistake, the war horse is likely to be unusable." ”

When everyone heard this, their hearts sank, and they looked carefully at the horse's hooves.

Yang Hao asked everyone to step back, and selected a few from a large pile of horseshoe copper that looked similar to horseshoe, and after trying a few, they were all slightly flawed.

However, Yang Hao believes that this will not have much impact.

Place the horse's hooves on your lap and carefully nail the horse's shoes into it with a small hammer.

In order to prevent the nail from being deviated, Yang Hao nailed it very slowly, and tried to make his hand as steady as possible.

The war horse leaned his head over from time to time and sniffed Yang Hao, as if he was curious about what the two-legged beast would do again, except for the occasional two snorts, he didn't react much.

In the frightened eyes of everyone, Yang Hao finally completed all the steps.

After putting the horse's leg down, he carefully examined it, and after thinking that there was no problem, he breathed a sigh of relief.
