Datang: Signed in to the Dragon Chair at the beginning, and was caught by Li Er.

After Li Zhi finished speaking at the limit speed, Li Shimin’s eyes gradually widened.

Follow the print of the horse’s hoof, and then see where it is easy to wear, make an iron mat and nail it to the horse’s hoof!

This…

This method…

This is so wonderful!

No, no, it’s not good anymore, it’s just amazing!

If you really follow Li Zhi’s method, then maybe you can really reduce the wear and tear of the horse’s hooves a lot!

After all, the places that are easy to wear are cushioned with iron cushions, so the horse’s hooves are naturally not easy to be worn!

Moreover, with an iron cushion underneath, when the horses walk on the stone road, they will not be easily scratched by the sharp edges of the stones!

The most important thing is that the iron cushion under the four horses’ hooves is a lot of money!

Even if a horse uses five thousand iron mats one after another, it is not comparable to the price of a war horse!

In the barracks, every month, war horses are injured due to daily training.

Even if only one batch of war horses are injured this month, it will be worth the cost of several months of horseshoe mats!

With such a simple account, Li Shimin will naturally calculate it.

However, the more he settled this account, the more his heart hurt.

If he had thought of this option a few years earlier, how much military money would he have to save?

If these military funds are used to buy war horses, then his cavalry will be more than now!

“Father, what happened to you? You can’t figure it out, right? Impossible! I’m so smart, my father shouldn’t be so stupid! ”

Li Zhi looked at Li Shimin, whose eyes were gradually dull, and even with a little remorse, asked with some doubts in his tone.

“How do you speak?” No big or small. What can you think of, you can’t think of? Don’t forget, no matter how clever you are, you also inherited it from here! Just now, I was thinking about who would be the most appropriate person to handle this matter! What do you little ass know? ”

…

Li Shimin was made red by Li Zhi’s words, and then rebuked Li Zhi even more harshly.

This kid said something, but he didn’t listen!

Why do you call you so smart, shouldn’t your father be so stupid?

Is this human language?

Li Shimin looked at Li Zhi, who was standing below, looking at himself with an innocent face.

That’s angry and funny.

His own son is so good, just going out for a walk, he came up with such a brilliant idea.

Although it has not been practiced, Li Shimin feels that this method is absolutely feasible.

Because if you just nail a patch to the horse’s hoof, although the horse may not adapt, it will definitely not say that it will stand in place and not walk.

“Father, you see that I can think of such a good method just by going out casually, which shows that the children still have too little knowledge in this palace. Otherwise, Father, you give me a warrant so that I can enter and exit the palace casually in the future? Maybe the next time your son goes out and comes back, he can bring something good to your father and emperor! ”

Li Zhi looked at Li Shimin, whose face was already full of excitement, and quickly took the opportunity to make his own request.

After Li Shimin heard his words, the gaze that looked at him suddenly became a little strange.

“I said that you kid has been around for a long time, and feelings are waiting for you here, right? I think you know the reasons for restricting your freedom. What’s more, you have made a great contribution this time! ”

From the moment when Li Zhi proposed the concept of horseshoes and took advantage of Li Shimin’s pleasure, he took the opportunity to propose a warrant to be able to enter and exit the palace freely.

Li Shimin’s view of Li Zhi has changed.

This kid’s mind is definitely not much worse than that of ordinary people from years ago.

The young man is old, and he is very wise and close to the demon.

Therefore, when talking to Li Zhi, Li Shimin’s attitude also quietly changed.

“Isn’t it a security issue! Father, how about you arrange a personal guard for me? In this way, I will take the guards with me when I go there in the future, and my safety will not be guaranteed!” Don’t be more, just thirty or fifty people! ”

Thirty or fifty people, which is really not much for a prince who has already been crowned king.

But when Li Shimin heard that Li Zhi wanted not only a pass, but also a person.

The first thing that came to mind was that this kid was wandering around the street with a large group of guards.

Even seeing who is unhappy, directly letting people beat him and other pictures constantly echo in Li Shimin’s mind.

“You are still young, and it is still not suitable to have too many guards, otherwise it is inevitable that people will gossip.” In this way, let Li Junxian follow you for a while in the future, and when you grow up, your father and emperor will assign you guards. As for the pass warrant, you can take the waist card of Shu, and when the time comes, Shun will order it. ”

After Li Shimin finished speaking, Wang De hurriedly took out a small golden sign from the side.

It is engraved with four small characters as if you were in person.

“With this in the future, you can go in and out of the palace at will. However, if you want to go out of the palace, you must take Li Junxian with you. ”

“Hey! No, Father, how can this be one? You can’t forget your daughter-in-law, will you? In case Hui’er wants to come to me in the future, she can’t even enter the door, isn’t it very inconvenient? Father, don’t be so stingy! Give another one! ”
