Datang: Time travel in two months, wait online, hurry up!

After all, the victory or defeat of a war is actually the mastery of details by the generals on both sides.

"Duke Wei is really meticulous!"

Li Ke couldn't help expressing his admiration for Li Jing from the bottom of his heart.

"His Royal Highness King Wu praised it absurdly. I just attach great importance to horseshoes."

Li Jing smiled and shook his head.

As a leading general, he often faces a problem.

That is, the horse's hoof of the war horse is severely worn and cannot be used anymore.

And cavalry is the main theme of war in this era, and it is also a big killer on the battlefield!

If the hooves of the war horse are worn out, it means that it loses its fighting power, which undoubtedly makes him very sad.

This can be regarded as an occupational disease, so when he saw the horse running on such a hard concrete road just now, he subconsciously thought that the horse's hoof was worn out.

After hearing Li Jing's words, the other generals also paid attention to it, checking the horse's hooves one after another.

as predicted.

As Li Jing said, the hoofs of these horses were worn to varying degrees.

This wear is far greater than the speed of wear on mud.

In other words, horses walking or running on concrete roads will greatly reduce the service life of a horse!

Thinking of this, Li Shimin and others couldn't help frowning.

Datang's horses are neither too many nor too few.

But if the horseshoe 893 wears down at the speed of wear, then the horses are definitely not enough.

Moreover, if the service life of a horse is reduced too much, the cost of using the horse will be very high!

"So, this concrete road is only for pedestrians?"

Li Shimin couldn't help but feel a little helpless. With such a good road, it can greatly increase the driving speed.

But there is another fatal flaw.

The other ministers also frowned, obviously this question was a bit tricky.

Or just walk pedestrians.

If you use a carriage, it can only reduce the service life of the horse and increase the cost of using the horse.

But neither is perfect.

Seeing this scene, Li Chengqian couldn't help but feel happy.

He was really shocked when he saw the concrete road just now.

I was desperate at first, Li Ke has cultivated such a good way, father and emperor will definitely reward Li Ke heavily.

But he didn't expect that Li Kexiu's path would have such a major flaw!

A road that a horse-drawn carriage cannot drive on is not as good as a dirt road!

"Actually, this is not without a solution."

At this time, Li Ke stood up again and told everyone that he had a solution.

"Oh? Say it!"

Hearing this, Li Shimin's eyes lit up immediately, and he quickly looked at Li Ke.

That's right, Li Ke is the inventor of cement roads, and he must know the advantages and disadvantages of cement roads better than anyone else.

Maybe Li Ke knows how to solve the problem of horseshoe wear on the concrete road?

Li Jing and the others also looked at Li Ke expectantly.

"Excuse me, father and ministers, do you feel any discomfort walking on this concrete road?"

"Such as the skin on the foot is scratched, or pain?"

Li Ke didn't rush to say a solution, but asked them a question.

"Of course not, how could I scratch the skin when I wear shoes?"

Li Shimin glanced at Li Ke inexplicably, then shook his head.

The same goes for other ministers.

"If you wear shoes, it won't scratch the skin. If you wear shoes, the horse's hoof will naturally not be worn."

"So, as long as you put horseshoes on the horseshoes and put shoes on the horseshoes, it will naturally solve the problem of horseshoe wear!"

Li Ke smiled slightly and said his solution.

It's actually a horseshoe!

Before he crossed over, he specially studied the knowledge of Mal's three-piece suit.

Horseshoes, saddles, stirrups.

Originally, he planned to take out the horseshoe after the concrete road was repaired.

In fact, his palace has secretly built some three-piece suits.

Unexpectedly, Li Jing discovered the wear and tear of the horse's hoof today.

"Shoes for horseshoes? Horseshoes?"

Li Shimin couldn't help thinking when he heard this.

It seems to be such a truth!

The reason why people don't scratch their skin when walking on the cement road is because they wear shoes.

Then put shoes on the horse, wouldn't that be all right?

Why can't I even understand such a simple thing?

The other ministers also nodded after listening, their eyes full of sudden realization.

Wonderful!

"His Royal Highness King Wu's thinking is really flexible, unlike my thinking is restricted."

Li Jing couldn't help but praised Li Ke.

Their thinking is limited, thinking that people need to wear shoes, but they have not thought about the matter of horses wearing shoes.

They didn't even think to write about it.

Horses are born with hooves, what shoes should they wear?

But Li Ke's thinking is completely different from theirs.

People can wear shoes, why can't horses wear shoes?

"But, won't wearing shoes on a horse's hoof affect running?"

At this time, Li Chengqian couldn't help standing up and questioning.

He really couldn't sit still anymore, he really didn't expect that Li Ke could think of a way!

Hearing Li Chengqian's words, everyone nodded.

Will wearing shoes affect the horse's running?

What's the point of reducing the problem of hoof wear if the horse can't run?

"Horseshoe shoes are naturally different from our human shoes. They are a kind of horseshoe tailored according to the horseshoe, which will never affect the horse's running."

"Moreover, because the horse's hoof is not afraid of wear and tear, the horse runs without any burden, will run faster, and its service life will be greatly improved!"

Li Ke smiled, and answered Li Chengqian's question confidently.

"Did you already figure it out?"

At this time, Li Shimin glanced at him suddenly, and asked a faint question.

"Ahem, I just created some this morning."

Li Ke glanced at Li Shimin in surprise.

Good guy, I haven't seen you for a few days, Lao Li has learned to be smart!

Hearing Li Ke's words, Li Shimin's eyes flashed a look that really happened.

This kid always likes to hide and hide, and he doesn't know how to take out good things.

Li Jing had to take the initiative to discover this problem before Li Ke told about the horseshoe.

Otherwise, when Li Ke took the initiative to say it, I don't know when it will be.

"Get someone to pick it up, everyone is here today, just to try the effect."

Li Shimin couldn't wait any longer, so he asked Li Ke to arrange someone to pick it up.

"Yes!"

Li Ke called a person from the palace and asked him to go back to the palace to fetch some three-piece suits.

Yes, in addition to horseshoes, stirrups and saddles are also arranged!

The three brothers have to be neat and tidy!

Not long after, people from the palace sent several sets of three-piece suits.

Because Li Ke nailed horseshoes on horseshoes in the palace and tested the effect.

Therefore, the grooms of the palace can be said to be relatively skilled in nailing horseshoes.

In front of Li Shimin and others, they put horseshoes on the hooves of the five horses.

"You can try again now."

Li Ke smiled slightly and looked at Li Shimin and the others.

"Let the carriage run back and forth on Suzaku Street to see the effect."

Li Shimin waved his hand directly and let the carriage run away.

Suzaku Street is 5000 meters long, and one round trip is [-] meters.

10 kilometers away!

However, a horse with a horseshoe on seems to be like a person wearing shoes. This time running on the concrete road, it seems to have a sense of security!

He ran wildly and recklessly, faster than before!

Seeing the carriage rush out with a swish, Li Shimin and the others were suddenly filled with surprise.

Not long after, the carriage came back.

The groom immediately lifted the horse's hoof, and everyone saw the condition of the horse's hoof.

It is found that the wear is basically the horseshoe, and the horseshoe is not in direct contact with the cement road!

Without contact, the horseshoe naturally has no wear!

As for the horseshoe, because it is made of iron, the wear resistance is stronger than that of the horseshoe, I don't know how many times!

Besides, once the horseshoe is worn out, just replace it.

Now Datang's iron output is not what it used to be, it is very sufficient!

"The cost of replacing a horseshoe is minuscule compared to the cost of replacing a horse."

Li Ke smiled and told everyone about the huge difference in cost.

"Good! Great!"

Li Shimin became excited when he saw the magic of the horseshoe.

He is the emperor on horseback, so he naturally understands that horseshoes can not only allow horses to run on concrete roads.

He also realized that the bonus of horseshoes to war horses is also very large!

War horses are the greatest support for the combat effectiveness of a cavalry!

Thinking that all the war horses of the Tang Dynasty have been nailed with horseshoes, the combat effectiveness of the cavalry of the Tang Dynasty will definitely be improved qualitatively!
