The Zhenguan Hall of Luoyang Palace, which originally belonged to the queen's bedroom, is now occupied by Li Shimin.

In addition to serving as a dormitory, the main hall also shouldered the role of the imperial study, somewhat similar to the Yang Xin Hall of the Forbidden City in later generations, where Li Er Majesty handled government affairs during his tour.

At this moment, Li Shimin was discussing political affairs with several important ministers, such as spring sowing matters, such as the etiquette of sacrificing to Emperor Wen of Han.

Sacrificing to the former Ming monarch, showing the people of the world their determination to emulate the sages and make great efforts, and the confidence that surpasses their achievements, the emperors always like to put on a show like this, and put gold on their faces.

As the monarch and the minister were talking, Li Zhi, the king of Jin, and the princess of Jinyang ran in excitedly.

Li Shimin's face sank slightly, and he had explained that the prince's children could not be disturbed when dealing with government affairs, let alone intruded. Of course, if there is an emergency, you can send someone to tell you.

Although Li Zhi and his son-in-law are favored, they are no exception, fortunately, a pair of children are very obedient and have never exceeded the rules, but today......

Li Shimin's face was a little unpleasant, but his eyes were still full of love when he looked at the two children, and there was no hint of blame.

The child is young and ignorant, how can he be willing to blame? The one who should be blamed for this matter is the palace maid who follows and takes care of it, as well as the guards stationed in front of the palace.

In fact, a group of chamberlains, palace maids, and guards outside the hall were all crying and depressed. They want to stop it, but once His Royal Highness the King of Jin and the most favored Princess Jinyang "go crazy", how can they stop it? How dare you stop it!

"Father!" Princess Jinyang had a bright smile on her face and ran towards the throne with small steps.

Li Shimin said gently: "Son, my father is handling political affairs, you go out to play with your slave brother first." Childish slave, take your son out first......"

Princess Jinyang hurriedly said: "Father is not in a hurry, my son and the ninth brother have found a treasure." ”

"What baby?"

The important ministers on the side all looked at it with a smile, and they didn't take it seriously in their hearts, and they didn't think about the little princess's "nonsense" behavior. After all, children are ignorant, and it is not a formal and important occasion, so there is no hindrance.

"Brother Jiu, quick!" Princess Jinyang pulled Li Zhi forward together, held up a round piece of iron, and said with a smile: "Father, this is it, the shoes made for horses." ”

Horse shoes?

Li Shimin and the ministers were confused, what kind of joke was the naïve little princess?

"Son, this ...... What is this? Li Shimin finally set his sights on his nine-year-old son.

Li Zhi said: "Father, this thing is called a horseshoe, or a horse's shoe, nailed under the horse's hoof, it is equivalent to a horse's shoes." ”

"What's the use?"

Li Zhi said leisurely: "My sister and I went to the stable and saw a lot of horses' hooves worn...... After nailing it, they were able to gallop again. ”

Hearing this, Li Shimin, who had been galloping on horseback for half his life, and several ministers present changed their faces, and they were already keenly aware of the key point.

Li Shimin didn't have a trace of unhappiness in his heart, and Wen Yan asked, "Childish slave, where did this thing come from?" ”

Without waiting for Li Zhi to answer, Princess Mengmeng Jinyang preemptively said: "Father, it's pitiful that the horse has worn out its feet...... The one who didn't have a long beard and kept Brother Jiu's forehead from piping hot... Said to put shoes on the horses...... Then he made this iron shoe with Brother Jiu. ”

It was a very naïve and strange expression, but everyone understood it, and Li Shimin was surprised: "Childish slave, is it made by Xie Yi?" ”

"Hmm!"

"What about others?"

Princess Jinyang smiled: "He went back to sleep, and when he left, he said, show the horse's shoes to his father." ”

Cheng Zhijie said: "Your Majesty, this thing ...... Why don't you ask a man from Huaiyang County to explain? ”

"Father, there's a horse in the stable that has been nailed to the horseshoe!" Li Zhi reminded in time.

"Let's go, let's see!" Li Er's majesty immediately got up, and as for the matter of sacrificing Emperor Wen of Han, he was immediately left behind. These things are more important than this horseshoe.

……

Next to the stable, Wang Yongan and a group of soldiers of the forbidden army were staring at the horse's hooves and discussing enthusiastically.

I thought it was a nonsensical joke, but I didn't want it to come true in a blink of an eye. As good riders, they quickly discovered the extraordinary utility of this thing, and they are now amazed.

What they didn't expect was that the emperor came in person with several important ministers of the Zhu State.

"Where's the nailed horse?" After the mountain called long live, Li Shimin went straight to the point and asked.

Wang Yongan hurriedly led the horses and raised the horses' hooves to show the emperor and several princes.

"When you nail the iron palm, Marco hurts?"

"Back to His Majesty, Ma was slightly uneasy, but not in pain. The horse's hooves are thick and the nails are short, so they can't hurt the horse's flesh, but there should be tricks to it, so you need to be cautious. Wang Yongan replied very seriously.

"How did you feel after you rode it?"

Wang Yongan said: "Back to Your Majesty, with this thing, the horse's hooves will not touch the ground, and it will not be worn out due to the rugged ground; Moreover, this thing is made of iron, which can cling to the ground, so it can run more steadily, and the horse's hooves will slip much less. ”

"Your Majesty, this thing is not simple!" Cheng Zhijie sighed: "Every year, there are many war horses in the army that are replaced due to the wear and tear of horses' hooves, especially after the war... I have been suffering for many years, and I don't want to be solved by this little piece of iron today. ”

"yes!" Li Xiaogong also said: "Over the years, many people have thought about how to reduce the wear and tear of horses' hooves, but no one has thought of nailing iron pieces on flesh and blood......"

"Isn't it? A lot of good things have not been discovered because they were not expected. Li Shimin sighed lightly and instructed: "Let the craftsman make the horseshoe, try what kind of shape is the best, and how long is the most secure iron nail...... Then give priority to equipping the Forbidden Army's mounts. ”

"Yes!"

Li Shimin emphasized: "Remember, don't spread today's events, and don't make a noise after the forbidden army assembles the horseshoe. As for the cavalry of the whole army, we will talk about it later. ”

Everyone understands in their hearts that although the Turks have been pacified, there are still strong enemies around the Tang Dynasty, Xue Yantuo is ready to move, and the Tubo people in the west are eyeing each other, those are all strong enemies in the world where cavalry is rampant, and they can't be allowed to take advantage.

……

After everyone dispersed, Fang Xuanling stepped forward and said: "Your Majesty, the minister has already inquired, the matter of riding a horse was mentioned by the King of Jin, and it was Xie Yi's mention to come to the stable." Her Royal Highness Princess Jinyang was kind-hearted, and after seeing the wear and tear of the horse's hooves, she begged Xie Yi to find a way, and then she had this thing. ”

"So, it's a coincidence, but he already has a blueprint in mind?" Li Shimin asked in a deep voice, his eyes leisurely.

Fang Xuanling said: "It should be, today happened to be a chance, so it was made." ”

Li Shimin scolded with a smile: "This kid didn't come to me in person, but let the two children ......"

"Your Majesty, the King of Jin and His Royal Highness the Princess seem to be very happy, and it is said that Xie Yi once inspired His Royal Highness the King of Jin to think of a way." Fang Xuanling said: "His Royal Highness the King of Jin is very teachable, and he seems to have gained a lot of knowledge. ”

Li Shimin sighed lightly: "Well, the young slave is shy, it's rare to see him so active, so excited, Xie Yi really has some way." Especially this horseshoe, it is of great significance, and the credit is not small, and it is worth giving him this Huaiyang County man! ”

Fang Xuanling said leisurely: "The previous theory of the new crop was not announced to the public, and if he was given a county man, there must be a lot of people who complained, but now it is justified and well-deserved." ”

Li Shimin's expression was relaxed, and he said with a smile: "That's okay, I was worried about his new crops, but now I see his whimsical ideas, I think it will not be without purpose, wait for the good news!" ”

Fang Xuanling said: "Hou Junji reported that Xie Yi's family and good seeds are on the way, and they will arrive in Luoyang in a few days.

As His Majesty said, the next thing is to wait for the good news and wait for the autumn harvest. ”
