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

In addition to being a residence in the bedroom, the main hall also shoulders the responsibility of an imperial study, which is somewhat similar to the Heart-Soul Hall in the Forbidden City in later generations. During His Majesty Li Er's visit, he handled government affairs here.

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

The sacrifices to the wise kings of the previous generations, and to show the people of the world that they have the determination to imitate their ancestors and work hard to govern, which exceeds their confidence in their achievements. The emperors always like to show off like this and put gold on their faces.

As the king and his minister were talking, King Li Zhi of Jin and Princess Jinyang ran in excitedly.

Li Shimin's face slightly darkened. He had always had an explanation that the prince's children should not be disturbed or indiscriminately when handling government affairs. Of course, if there is an urgent matter, you can send someone to report it.

Although Li Zhi and Yizi are favored, they are no exception. Fortunately, their children are very obedient and never surpass the rules, but today...

Li Shimin's face was a little bad, but his eyes were still full of kindness when he looked at the two children, without any intention of blaming him.

How could he bear to blame the child when he was young and ignorant? The ones who should be asked about this are the eunuchs and palace maids who were taking care of him and the guards stationed in front of the hall.

In fact, a group of eunuchs, palace maids and guards outside the hall were all mournful and extremely depressed. They wanted to stop him, but once His Highness King of Jin and the most favored Princess Jinyang became crazy, how could they stop him? So how dare they stop him!

"Father!" Princess Jinyang smiled brightly and ran towards the imperial throne with a small step.

Li Shimin said gently: "Yizi, my father is handling political affairs. You should go out to play with Zhinu's brother. Zhinu, take Yizi out first..."

Princess Jinyang hurriedly said, "Father, no hurry, Yizi and Jiu Ge found a treasure."

"What baby?"

The important officials on the side all looked at it with a smile, not taking it seriously, and did not disobey the little princess' "nonsense" behavior. After all, the child is ignorant and not a formal and important occasion, so it does not hinder.

"Brother Jiu, hurry up!" Princess Jinyang pulled Li Zhi forward together, raised a round iron piece, and smiled and said, "Father, this is the shoes made for the horse."

Horse shoes?

Li Shimin and the ministers were confused. What joke was this innocent little princess playing?

"Shizi, this... a slave, what is this?" Li Shimin finally turned his eyes on his nine-year-old son.

Li Zhidao: "Father, this thing is called a horseshoe, or a horseshoe. If nailed under the horseshoe, it is equivalent to a horse's shoes."

“What’s the use?”

Li Zhi said, "My sister and I went to the stable and saw that many horse hooves were seriously worn... After nailing this object, they could gallop and run again."

Hearing this, Li Shimin, who had been galloping on the horse's back for half his life, and the ministers present, had changed their faces, and they had already keenly realized the key point.

Li Shimin felt no more unhappy and asked warmly: "Zhi Nu, where does this thing come from?"

Before Li Zhi answered, the cute Princess Jinyang said first: "Father, the horse has worn out its feet so pitiful... The person who has no long beard and makes Brother Jiu's forehead not hot... said he wanted to wear shoes for the horse... and then made this iron shoe with Brother Jiu."

A very childish and strange expression, but everyone understood it. Li Shimin said in surprise: "Is it made by Xie Yi?"

"Um!"

"Where are others?"

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

Cheng Zhijie said, "Your Majesty, this thing...why would you like a man from Huaiyang County come and explain it?"

"Father, there is a horse in the stable with its horseshoes nailed!" Li Zhi reminded him in time.

"Let's go and have a look!" His Majesty Li Er stood up immediately, and as for the sacrifice to Emperor Wen of Han, he was immediately thrown away. These destructive things are not as important as this horseshoe.

...

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

I thought it was an irrelevant joke, but I didn't want it to be realized in a blink of an eye. As excellent riders, they soon discovered the extraordinary effect of this thing and were amazed at this moment.

What they didn't expect was that the emperor came in person with several important officials of the Pillar Kingdom.

"Where is that horse with iron palm nailed?" After the mountain shouted, Li Shimin asked straight to the point.

Wang Yongan hurriedly brought the horses and raised the horse's hooves to show them to the emperor and several dukes.

"When nailing the iron palm, does Marco feel pain?"

"When you go to Your Majesty, the horse is slightly uneasy, but it doesn't hurt. The horse's hooves are thick and the iron nails are short, so it cannot hurt the horse's flesh and blood. However, there should be tricks and be careful." Wang Yongan answered very seriously.

"How do you feel after you ride?"

Wang Yongan said: "When you go back to your Majesty, with this object, the horse's hooves will not wear due to the rugged ground; and this object is made of iron, which can be tightly pressed against the ground, and runs more steadily, and the horse's hooves will slip much less."

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

"Yes!" Li Xiaogong also said: "For many years, many people have thought of ways to reduce the wear of horse hooves, but no one expected to nail iron sheets on the flesh and blood body..."

"No? Many good things have never been discovered because they didn't expect them." Li Shimin sighed and ordered: "Let the craftsmen make horseshoes, try what kind of shapes and effects are the best, how long is the most reliable iron nails... and then give priority to the equipment of the imperial guards."

"yes!"

Li Shimin emphasized: "Remember, don't spread today's affairs, and don't make any noise after the imperial guards are equipped with horseshoes. As for the entire cavalry, I'll talk about it later."

Everyone knew in their hearts that although the Turks had been pacified, the strong enemies were still surrounded by Tang Dynasty. Xue Yantuo was ready to move, and the Tubo people in the west were eyeing them. Those were cavalrymen who were rampant in the world, so they could not take advantage of them.

...

After everyone left, Fang Xuanling stepped forward and said, "Your Majesty, I have already investigated it. The matter of riding a horse was mentioned by the King of Jin, and the proposal of coming to the stable was Xie Yi. Princess Jinyang was kind-hearted. After seeing the horse's hooves worn, she begged Xie Yi to find a solution, and then this thing came into existence."

"In this way, it was an accidental opportunity, but he had a picture in his heart?" Li Shimin asked in a deep voice, his eyes lingering.

Fang Xuanling said: "It should be that today happened to be an opportunity, so it was made."

Li Shimin laughed and scolded: "This kid, if he doesn't come to me personally, he will let the two children..."

"Your Majesty, the King of Jin and His Highness the Princess seem to be very happy. It is said that Xie Yi once inspired His Highness to find a solution." Fang Xuanling said: "Your Highness the King of Jin is very educated and seems to have gained a lot of knowledge."

Li Shimin sighed lightly: "Well, Zhinu is shy. He rarely sees him so proactive. He is so excited. Xie Yi really has some solutions. Especially this horseshoe, which is of great significance and has made a lot of contributions. It is worthy of being a man in Huaiyang County!"

Fang Xuanling said leisurely: "The previous statement of new crops has not been announced to the public. I have to give him a county man. There are many people who have complaints, but now it is reasonable and well-founded, and deserves it."

Li Shimin looked relaxed and said with a smile: "That's good. I was worried that his new crops would be irrelevant, but now I see him having a wonderful idea. I think I will not be aimless and wait for the good news!"

Fang Xuanling said: "Hou Jun gathered and reported that Xie Yi's family and good seeds are on the way. He will arrive in Luoyang soon. The nursery land has been sorted out and the spring is full of energy and you can sow seeds at any time.

As Your Majesty said, you only need to wait for the good news and wait for the harvest in autumn.”
