Wu Jue thought about it all night, thinking about the reason while running for his life.

Either Zong Shu found a new good breed horse, or he invented a horsepower-enhancing drug.

I just didn't expect that it was the Liao people's horses that had problems.

Horseshoe, in fact, is the horse's toenails, professionally called: cuticle.

The stratum corneum belongs to the skin of horses and is made up of the epidermis, dermis and subcutaneous tissue.

The hoof is divided into four parts: the hoof edge, the hoof crown, the hoof wall and the hoof bottom.

Once the bottom of the horse's hooves is worn out, the horse's dermal tissue is underneath, and the horse can't even walk.

Since it is a stratum corneum, this stratum corneum can also grow, but for a longer period of time.

The cavalry of the Liao people first fought with Yang Keshi's cavalry in Langoudian.

Langoudian is a beach in Baiyang Lake.

The beach was damp, and the hooves of the Liao people were already stained with water.

Later, the horses of the Liao people stood on the bloody ground for several hours, and the cuticle at the bottom had already been soaked and softened.

So when they chased Zong Shu, the horsepower consumption was particularly large.

It's not that the Liao people are unhelpful.

The soaked soft horseshoe is easy to grind off, and the meat is quickly visible.

At this time, no matter how strong the horse is, it can't continue to run.

Zong Shu said that he also brought a lot of broken glass ballast from Bianliang, which was a defective product left by Lin Lingsu when he made glass.

He also brought some broken porcelain from the Zong's porcelain workshop and spread it on the official road outside the village.

The hooves of the Liao people have softened, and these glass ballasts and broken porcelain pieces are easy to penetrate into the hooves.

This is an important reason why the Liao army turned on its back on the official road.

"I understand that our hooves have not been soaked, but have been walking on dry roads, and the loss of the hooves is relatively small."

Wu Jue said again: "In addition, the cavalry of the Liao people ran through the fields on both sides of the official road for a while, and at this time, the ice and snow melted, and the fields were wet, which accelerated the softening of the hooves of the Liao people's horses. ”

"General Wu, draw inferences from one case and admire it." Zong Shu praised.

Where does Wu Jue dare to put on the general's shelf now?

Zong Shu has arranged everything since he "kidnapped" himself, one action after another, interlocking, and there is no last resort.

He may have planned it several days in advance, and he just followed the process and led the Liao army to the abyss step by step.

When they came to the edge of the abyss, the Liao army woke up, and it was too late.

For Zong Shu, Wu Jue is now a hundred, ten thousand admirers.

Wu Jue hurriedly said: "Young Master Zong, you can't do it yet, if you don't understand something, please don't hesitate to give advice." ”

After Li Shaoyan's introduction, Wu Jue knew that Zong Shu was not the identity of the East Palace attendant at all, but the person who the prince called "Grandmaster".

Wu Jue couldn't rashly call Zong Shu "Grandmaster", he could only call him Young Master Zong.

After Zong Shu finished talking about "first", he found that Wu Jue and the Seed Master Dao no longer went down the question, so he no longer explained the "second".

The real reason why one of his own horses is better than the three horses of the Liao, he doesn't want too many people to know at the moment.

The real reason for this: horseshoe.

Zong Shu nailed horseshoes to all thirty-five horses.

When he was in Caojiazhuang, Zong Shu handed Cao a drawing and drew an iron piece, which was a horseshoe.

Cao Yishou made a horseshoe according to the pattern, and together with Niu Gao, he nailed the horse to the palm.

The horse resisted at first, but Cao Yishou and Niu Gao had great strength, tied the horse up, and at the same time put the iron palm into the fire.

After the iron palm was red, Cao held the iron palm in one hand and stuck it directly to the bottom of the horse's hoof, and the iron palm merged with the cuticle of the horse's hoof.

Immediately afterwards, Cao put another nail in the horse's shoe to ensure that the horse's shoe and the horse's hooves were more tightly combined.

In other words, Zong Shu's horse is protected by an iron palm and will not be hurt and worn at all.

Because, all that is worn is the horseshoe.

The use of horseshoes not only protects the horse's hooves, but also gives the horse's hooves a firmer grip on the ground.

It was also through the official road covered with wheat straw that the Liao people's horses slipped and fell, while Zong Shu's horses were fine.

Horseshoe was first invented by the ancient Romans around the first century BC, and the earliest record of horseshoe in China is about five generations.

In the third year of the Later Jin Dynasty, Gao Juzhi, the judge of Zhangwu Jiedu, sent an envoy to Khotan, and began to enter the vast Gobi from Ganzhou, where the Uighur tent was stationed at that time.

As far as the eye can see, the road ahead is full of sand and gravel, and it is very difficult to walk.

At this time, the people of Ganzhou taught them a technique, "teaching the Jin envoys to make horseshoe wood astringent, wood astringent four tricks, horse hooves are also chiseled and embellished with four tricks, and camel hooves are wrapped in yak skin."

"Mu astringent" is the common name of the Ganzhou people for the horseshoe at that time.

At that time, the Ganzhou Uighurs in the Hexi Corridor had already mastered the technique of nailing horses.

However, it was not widely used by the Mongols until the Yuan Dynasty.

Of course, the current Liao people and Jin people don't know how to use horseshoe.

If the Liao people and Jin people knew how to use horseshoe, the Great Song Dynasty would not be able to stop these grassland cavalry.

Out of caution, until there is no new technology, the secret of the horseshoe is limited to Cao Yishou and the current thirty or so people.

Seed Master Dao and Wu Jue didn't ask, and Zong Shu naturally couldn't take the initiative and explain it.

Just now, the breeder Dao was still worried that Niu Gao and others would chase the Liao people, whether they would let the Liao people escape, after all, they had just changed horses for the third time.

Zong Shu explained like this, the master of the Taoist Dao, Yelu is not talented, and he can't run away.

But after thinking about it, if Niu Gao and others want to catch Yelu Bucai, I'm afraid it won't be easy, especially if Zong Shu asks to catch him alive.

Seeing the worry of the seed master, Zong Shu said: "Niu Boyuan's martial arts are probably no worse than Jin Qing. ”

Wu Jue said: "Niu, General Niu's martial arts, I have seen it yesterday, I am not his opponent. ”

Only then did Wu Jue tell him about the fact that he was intercepted in the middle of the road yesterday, and only then did the seed master Dao know that the purpose of Zong Shu's trip north this time was to save him and Wu Jue.

Looking at this young man again, Planter Dao suddenly felt that he had lived to be seventy years old, and the loess had already wrapped around his neck, but compared to Zong Shu, his seventy years had been in vain!

Before he set out on the expedition, this young man said in the court that the attack on Liao would be defeated because we underestimated the strength of the Liao army.

Looking at it now, no matter which one it is, it is not what Zong Shu expected.

Seed Master Dao thought of another result, if it was His Royal Highness the Crown Prince who grabbed the task of the Northern Expedition to Liao, then Zong Shu must have gone on the expedition.

Without Zhao Gou and Tong Guan, they were replaced by the crown prince and Zong Shu.

So, the losing side, that is the Liao State? Yanyun Sixteen Prefectures, then you can take it back!

Even if the crown prince did not go on the expedition, even if he listened to Zong Shu's advice yesterday and Yang Keshi did not go on the expedition, he persuaded Tong Guan to adopt the deterrent strategy of "not attacking and not retreating", maybe the sixteen states of Yanyun could also come back.

If he listened to Zong Shu's advice, or left Zong Shu in the Seed Army, maybe the war would have been another result.

Unfortunately, there are no ifs on the battlefield, only results.

Looking at Zong Shu's young and excessive face, Seed Master Dao felt that this person was really terrifying, with terrifying strength!

The seed master always refused to accept the old before, but now he finally feels that he is really old.
