"Horseshoe? Shoes made of iron for horseshoe? ”

After listening to Li Huan's report, Li Shimin's eyes widened, and he felt as if he was listening to a joke - did his eleven Lang have his head squeezed by the door, or did he fall down the steps and knock down? How would you put shoes on a horse?

"Yes, Your Majesty!"

Li Shimin can slander his brother in his stomach, Li Jian didn't have the guts, but he just explained 1510: "Now all the horses in King Xu's mansion have been nailed to this kind of horse shoes. The king called it a horseshoe, and sometimes a horseshoe! There are also some people who have seen horseshoes, such as the son of Luzhou Beijia and others, who have also nailed their horses to horseshoe...... Although the time is still short, I can't see anything, but the king once said that it can protect the horse's hooves from wear and tear, and the effect is good! ”

Li Yuanjia probably didn't expect that he didn't plan to tell Li Shimin about the horseshoe, but Li Jian secretly brought this thing back to Chang'an.

And this time, Li Jian was quite satisfied with his preparation.

Last time, because he didn't know anything about Qu Yuanli, and he didn't bring things back in advance, Li Jian was reprimanded by the emperor! Although Li Yuanjia, the king of Yu, did not plan to pay tribute to the emperor this time, Li Huan, who had a good eye, would not miss it, and directly asked Luzhou to inquire about what new things were in the Xu Wangfu and bring them back together!

Among them, there are several pairs of horseshoes.

And according to the guy who galloped back in advance to report the news, all the horses in the royal convoy were equipped with this thing, and the horses' hooves were really not affected in any way after walking thousands of miles down the way! There is no need to be like his people, who have to take care of horsepower every day, and dare not let it run for too long.

"Hmm......"

Touching the short beard under his chin, Li Shimin groaned.

As an emperor on horse, of course he knew that the horse's hooves were easy to wear out, and once it cracked, it would be equivalent to abolishing this kind of thing, and he knew better that there were a lot of war horses in the army that were abolished every year! If this horseshoe really works, then Li Yuanjia has really done a good thing......

If you want to nail every horse, it's too scrap metal.

Li Shimin, who knew very well how much iron Datang could produce in a year, and how much of it was used to build weapons and other important things, shook his head, temporarily noncommittal about the horseshoe, and asked instead: "What about the Quyuan plow?" Can it be sent to Chang'an? ”

"Back to Your Majesty, I'll be here before noon tomorrow!"

"Very well, then you don't have to go into the city!"

After thinking about it for a while, Li Shimin said lightly: "Just find a field outside the city, prepare to plough the cattle, and we will try it outside the city tomorrow!" ”

"Huh? Out of town? Your Majesty......"

"Well, no need to say more!"

Knowing that Li Huan, who was panicked, was about to say something, Li Shimin didn't give him a chance to speak at all, and directly waved his hand and said: "If this Quyuan plough is really as light and convenient as you say, one ox and one person can drive it...... Hehe, after I saw it in person, it is estimated that all the civil and military officials of the Manchu Dynasty will go to see it, you have to be ready......"

……

After lunch the next day, Li Shimin left the imperial city surrounded by hundreds of guards.

Of course, it is said that it is going out of the imperial city, but in fact, this Taiji Palace ...... Oh, it's still called Daxing Palace, and it's the northernmost part of the entire Chang'an. It can be said that the entire imperial city occupies the position in the middle of the northernmost part of Chang'an City. The south gate is called Chengtian Gate, and the north gate is the famous Xuanwu Gate!

Xuanwu Gate is located in the remaining slope of Longshou Plain, with a high terrain, overlooking the palace city, and is the most important gateway.

Outside the imperial city, there are three major gardens belonging to the Tang royal family, namely the small West Inner Garden and the East Inner Garden, as well as the huge Forbidden Garden with an area of hundreds of square kilometers!

Anyway, pick any place, it's enough to twist the plow.

At the time set by the emperor, Li Jian naturally wanted to make the convoy of Xu Wangfu desperately arrive in advance. So when Li Shimin arrived somewhere in the Forbidden Garden with a large group of people, more than a dozen people from King Xu's Mansion had already knelt on the ground to greet them, and the two croppers who were picked out from the Zhuangzi of the King of Yu saw the posture of hundreds of horses galloping, and they began to tremble all over, and one of them almost peed his pants!

"Alright, let's all get up!"

After dismounting, he walked in front of this group of people, and Li Shimin saw the true identities of the two farmers at a glance.

The other dozen or so don't need to look at them, they are either Li Yuanjia's guards or the little servants in the house, only these two are even if they are dressed in clean clothes, and their faces and hair are cleaned up, but the "smell of the land" has never dissipated.

However, Li Shimin didn't pay attention to anyone at all, but came directly to the five Quyuan plows!

Bending down without any image, the emperor carefully looked at these things sent by his younger brother - when he saw them for the first time, Li Shimin's worries were immediately relieved - just looking at the size and length, they were much lighter than the plows he had seen before! In other words, at least one thing Li Jian said was not wrong, this thing must be much easier to control!

And as the name suggests, the plough is crooked!

To be carefully selected by Han Shan and sent to Chang'an City, these five plows are of course very straight in workmanship, and each part has just been carefully polished, which looks quite pleasing to the eye. However, after looking at it for a while, Li Shimin still straightened his waist, walked straight to the two croppers, and asked gently, "You two, can you use this Quyuan plow?" ”

"Yes, yes!"

"Goo-dong!"

Facing the emperor's questioning, one of the two people nodded desperately, and the other could only swallow saliva and couldn't say a word!

When they really saw the emperor, both of them were a little frightened.

In this case, both Li Yuanjia and Li Shimin are quite experienced, so after a few words of gentle comfort, Li Shimin waved his hand and said: "Okay, you have one plow, one cow, and you will plow the land here for me to see!" ”

When the emperor spoke, naturally no one dared to slack off.

No matter how nervous they were, the two croppers had to move. Fortunately, the two of them were originally the kind of people who were more clever, otherwise they would not have been selected by Han Shan to come to Chang'an, not to mention that before leaving, in order to protect Han Shan, they also let the two of them practice for a whole day and night!

So the half-burnt incense has less time, and everything is already ready.

In fact, it's not just the two crop men who are nervous to death at this time, Li Shimin, who is calm at this time, is actually not calm at this time - for these small Quyuan plows in front of him, the emperor has no bottom at all!

He was afraid that the higher the expectation, the greater the disappointment!

You know, if this Quyuan plow is really so easy to use and can save a lot of oxen power and manpower, it means that Datang can reclaim more land and harvest more grain, for an emperor in the feudal era, there is nothing more important in the world than this!

And if they can't, they waste the emperor's feelings......

I didn't think about whether this Qu Yuan plough was from Li Yuanjia by himself, rather than someone taking the initiative to dedicate it to him, the corners of Li Shimin's mouth couldn't help twitching several times at this time, but he secretly made up his mind: If that's the case, you must teach Shiyi Lang a hard lesson!
