The frightened Li Chengqian got off the horse, turned his head to look at His Majesty Li Er and a group of old killers who came over, and struggled for a long time, deciding not to investigate who roared just now.

"Boy, the riding skills are good, so you haven't fallen off like this." Cheng Motou was still so bohemian, and walked over and patted Li Chengqian's shoulder lightly with his bear paw.

"Thank you, Uncle Cheng, for the compliment!" Although he knew that Cheng Motou didn't have any strength, Li Chengqian still felt that half of his body was numb.

"Boy, what's under your horse's hooves?" Yu Chi Lao Mo and Cheng bite Jin have a virtue, but Lao Cheng is pretending, he is real.

Li Chengqian was stunned by Wei Chigong's words, and turned his head to look: "There's nothing." ”

The old guy Wei Chigong simply didn't talk nonsense with Li Chengqian, and directly crossed him, came to his pony, bent down and fought lightly.

The poor pony was lifted upside down by the old lieutenant's hooves, and the four hooves nailed to the semicircular iron plates also showed up.

Raised to Li Chengqian, compared, the old lieutenant Chi found that it seemed that Li Chengqian was still not tall enough, so he had to put the horse on the ground again and suppress it, ignoring the neighing of the pony, and then pointed to the semi-circular iron piece and asked, "What is this?" ”

"Horseshoe!" Li Chengqian was a little inexplicable, what is there to ask about this, everyone knows it.

"What is a horseshoe? Boy, the war horse is not easy to get, don't toss it. Wei Chi let go of the pony, watched it run away without a shadow, glanced at Li Chengqian with disdain, then turned his head and walked back, and sighed at the end.

"Hey, hey, my horse!" Seeing the horse run away, Li Chengqian jumped to his feet in a hurry, and searched all over the harem to find an obedient little mare, so he was scared away by Wei Chigong.

And what is the attitude of that old guy just now, contempt? Disappointed? Okay! I don't know the horseshoe, but I'm embarrassed to be a general?

In the end, Lao Cheng was interesting enough, squatted in front of Li Chengqian, and said in a voice that he thought was relatively small: "Boy, the war horse is our best comrade-in-arms, and it is your closest partner on the battlefield, so treat them well." ”

"No, I ......." Li Chengqian still has a good impression of Lao Cheng, although he often bullies himself, but he has no bad intentions, just like the uncle next door teasing the child, but his way is a little special.

That Zhi Lao Cheng didn't give Li Chengqian a chance to speak at all, and then said: "Besides, you are a gentleman, what is the matter with riding a little mare?" ”

The two sentences that didn't match at all directly made Li Chengqian stunned, and he didn't react to his anger for a long time.

What's wrong with riding a little mare, Lao Tzu is only 8 years old, and he is not as tall as a horse's legs. When Lao Tzu is like a solid commodity in your house, he was pumped into a rolling gourd by a brain of melons, and he still jumped up and jumped up and down.

Spit and complain, His Majesty Li Er's next words are for his own life: "The prince misbehaved, mutilated the living ......, and punished ......." ”

"Father, my son has something to say!" Seeing that the old man's verbal will was about to come down, Li Chengqian dared to slack off, and hurriedly picked up the next sentence.

"What else do you have to say?" His Majesty Li Er asked in a deep voice with a gloomy face.

This little bastard is too capable of causing trouble, so even if the horse has to be tossed, can't he go back to the 'Lanruo Temple' to toss? I had to run outside and toss.

Now he was seen by the courtiers, how to protect him.

Looking at Lao Li's face, Li Chengqian was also entangled, what is 203 or 302 holes in Mogao Grottoes, isn't there a nail horsepalm diagram in it that opened the emperor for 4 years?

It stands to reason that the Tang Dynasty should have such a thing as a horseshoe now, but why did no one know the civil and military affairs of the Manchu Dynasty, and they had to punish themselves, is the information of later generations wrong?

But now is not the time to dwell on this, the emperor Lao Tzu is still waiting for him to reply.

"Father, the emperor and his sons thought that iron was more wear-resistant than the cuticle of the horse's hooves, so they nailed iron sheets to the horse's hooves. This increases abrasion resistance and also protects the integrity of the horse's hooves on rough roads. ”

"It's ......." Li Chengqian's theory undoubtedly caused a difficult problem for everyone, because no one knew whether what he said was true or false, and even Li Jing, who was rated as the god of war by later generations, pulled his beard and shook his head.

"How do you know?" His Majesty Li Er saw that it was difficult for everyone to make a judgment, so he asked.

"When the horse's hooves are worn, get an iron nail on it, and you will know it naturally." Since no one in the Tang Dynasty knows about the horseshoe, Li Chengqian will not be stupid to talk about the Mogao Grottoes, a rumor that is a rumor for later generations, but he is afraid that the consequences will be unpredictable, it is better to say that he invented it himself.

As for the fact that someone really discovers that there is this mural in Mogao Grottoes in the future, it is a big deal to say that he has an idea and uses the accident and inevitability of history to teach this group of illiterate people another lesson.

"Your Majesty, the minister thinks you can give it a try, if what the prince said is true, it will be beneficial and harmless to my Tang Dynasty." Li Jing, who is old and serious, first suggested.

"The prince has ready-made ones, what else to try." The old lieutenant, who had scared the horse away, jumped out again.

"Ran!" Li Chengqian helplessly pointed in the direction of his pony's escape.

"Just catch it back, there is only that little mare in the camp, and it is very conspicuous." The old lieutenant said with a grin, completely ignoring Li Chengqian's black face.

Didn't Lao Tzu just ride a little mare, safety first, so that the whole camp would know it.

However, Wei Chigong was right, and the order was passed down not long before the little mare was brought back. Because this stupid fellow didn't run far at all, only ran out for about a mile, and when he saw that no one was chasing him, he stopped, and was picked up by the sentinels outside.

There is no shortage of rocks on the Dragon Head Plain, except for some well-groomed fields, there are rugged mountains everywhere.

Naturally, Li Chengqian can't be allowed to go to the test, he is the crown prince, and it is difficult to explain if he bumps into it.

Therefore, the eldest Cheng Chuliang was assigned this task by Comrade Cheng Lao, and rode a little mare with great disdain, like a bear riding a mule, and rushed into the wilderness like a wild donkey with a burst of cheers.

After about a quarter of an hour of running, the poor little mare finally returned to Li Chengqian's side, and the poor guy was already walking straight and swaying under the pressure of Cheng Chuliang, and he couldn't ride it.

"Your Majesty, the minister thinks that the horseshoe is indeed very useful." Wei Chigong once again checked the hooves of the little mare in the way of four horses, and bowed to Li Er.

"Hmm. What do you think? His Majesty Li Er nodded and asked out loud.

Seeing Cheng Chuliang's wild performance in the wilderness on a pony, the battle-hardened Tang generals all understood that if it was an ordinary horse, it would have been lame by now, and the little mare with a horseshoe nailed to it couldn't stand up except for being tired, and it didn't seem to have any other problems.

"Your Majesty, it was the minister who first discovered that the sound of the prince's horse's hooves was different, so he should equip the minister's right guard first." The advantages of the horseshoe were seen by everyone present, and Wei Chigong naturally saw it.
