Yu Qin, the Minister of Works, sat in his house, took a sip of hot tea, and moved his body. This day was pretty good. Recently, several palaces were almost completed as scheduled, and the Ministry of Works had no major tasks to do. The Minister of Works was considered to be idle. After the payment, he could go to Pingkangfang...

"Shangshu Yu, the Crown Prince is coming down!"

A subordinate hurriedly ran into the house. After hearing this, Yu Qin opened his half-closed eyes: "Who is here?"

"Your Highness the Crown Prince!"

"Just say I'm not here!"

After Yu Qin finished speaking, he quickly went to the backyard of the Ministry of Works. There was definitely nothing good about the prince when he came. When he first came to the Ministry of Works, he took away ten carpenters including Zhu Youxiao, and later took away ten blacksmiths including Ou Zhizi. Now the Ministry of Works lacks carpenters and blacksmiths. If he took some people away for him, there would be no one in his Ministry of Works!

"Shangshu Yu, long time no see!"

Before Yu Qin could come to the backyard, Yu Zhigan's voice had already come. After hearing this, Yu Qin could only stop and change his face instantly. He turned to look at Yu Zhigan: "Your Highness, Prince!"

"Well, Yu Shangshu is exempted from gifts. Are my horseshoes ready?"

"It's done, I'm just about to send someone to the East Palace!"

"Since that's the case, take me to see!"

Soon, Yu Qin asked someone to bring the horseshoe that Yu Zhigan wanted. They were all U-shaped, but they had different thicknesses and different holes. They could be fixed to the horny veins by nailing them.

"Let's go and try it. Is it useful to install it right away?"

"Okay!" Soon, several horses were dragged out from the stables of the Ministry of Works, all of which were old horses. They could run errands in the Ministry of Works, and could not go to the battlefield or pull a cart. They were horses that retired to retire and retire.

"No, these horses have too thin horniness!"

Yu Zhigan glanced and shook his head. Although Yu Zhigan had never nailed a horse iron, he had seen it. Such a long nail was to nail into the horny skin. The horse's hooves were so thin...

"Is there a better war horse?"

"No!"

"Forget it, I'll take it back to the East Palace. By the way, you horseshoe workers go with me, just try it!"

When Yu Qin heard this, the corner of his mouth twitched slightly, but he did not refuse Yu Zhigan's suggestion. Soon, several blacksmiths were taken out and followed Yu Zhigan's back, leaving with tears in his eyes.

"Brother Liu, take care of yourself!"

"Brother Song, take care of yourself!"

"Brother Li, take care of yourself!"

The blacksmiths nodded vigorously, took a deep breath, and shook hands with their friends in the Ministry of Works. It was not like going to the Prince's Mansion, as if they were separated from life and death.

"Hey! Lao Liu and the others are going to suffer!"

A stern official from the Ministry of Works looked at the leaving blacksmiths and spoke slowly.

"Isn't that true? Zhu Youxiao, such a good person. He has been to the East Palace for less than a month and has lost two laps. He has not had much money yet. I heard that he works day and night in the East Palace, and only that mahjong has to make every day. If he can't make it, he won't give it to him!"

"Really? Your Highness the Crown Prince won't be so!"

"Can this be fake? I heard that the brother-in-law of Zhu Youxia's neighbor's neighbor said it personally. You will know when you meet Zhu Youxia in the future!"

"It's so scary. Fortunately, I'm not a craftsman, otherwise, hey..."

A group of people were talking behind their backs, and a minor official packed up the drawings in his hand, left the Ministry of Works staggeringly, and rushed towards the second prince's mansion. When the drawings were delivered, he could receive a bounty of 100 taels.

Speaking of the second prince, Yu Tai, during the last high ceremony, he first stole honey, but was bitten by various insects at night and became Marshal Tianpeng. Later, he learned from Yu Zhi to play with horse hooves, but he was kicked out of touch.

But it was not a big deal. According to Yu Zhigan's estimate, it was a concussion. The only thing that made Yu Zhigan worried was whether this guy would fall down like himself, a soul would travel over or get a system, but it seems that there is no one at the moment.

After the second prince woke up, he was silent for a while. Later, he asked his elder brother what he was doing. When he learned that his elder brother asked people from the Ministry of Works to study horse hooves, Yu Tai decided that he must make it first and get up wherever he fell!

So Yu Tai bribed a minor official from the Ministry of Works and reported his elder brother's movements at any time.

"Although I am not a forceful person, I, Yu Tai, must not be the laughing stock of others!"

Yu Tai looked at the drawings and sweared secretly that as long as he studied horseshoes, people would say in the future that the second prince was kicked by a horse in order to study the things that protected horseshoes. What a good prince, but he would not say that the second prince Yu Tai was kicked in the head with horseshoes!

“Is that true?”

The minor official of the Ministry of Works nodded: "Second Your Highness, yes, Your Highness the Crown Prince let us create this!"

"Do you know how to use it?"

"Just put this under the horse iron, this nail has a barb on it!"

The little official kept explaining the use of this horseshoe to Yu Tai. After hearing this, Yu Tai nodded and couldn't help but admire his elder brother. He still had something to do, so he could think of it!

“Are there any ready-made horse hoofs?”

"Yes, I have someone secretly do a few more to offer to the Second Highness!"

"Good work, go and receive the reward!"

"Thank you, Your Highness!"

The tiny official happily retreated, while Yu Tai looked at the horseshoe in his hand, looked at Qin Hui and Lai Junchen beside him: "Let's go, try it!"

In the East Palace, Su Dingfang held several of his war horses not far away, looking at the U-shaped iron piece in Yu Zhigan's hand curiously, not knowing what Yu Zhigan was going to do.

"I remember it seems to be burning red and then sticking it on, but try it first and don't burn it!"

Yu Zhigan thought for a long time but didn't think of a good idea. After all, he was not a professional talent. In the end, he decided to try it slowly and waved to the groom not far away: "You nail this thing to the horse's hoof!"

"Yes, Your Highness the Crown Prince!"

The groom is professional and comes into contact with horses every day, so it is very clear that there is something similar to a human fingernail, and it won't hurt even if you cut it off.

According to Yu Zhigan's idea, the groom cleaned the horse's hooves, then put the horse's hooves on the horse's hooves and then took out the nails and slowly nailed them in.

Soon, the four horses were nailed. After the groom led the horse two steps, the horses stepped on the bluestone slab and made a crisp sound. Yu Zhigan nodded with satisfaction.

However, as a rigorous scientist and inventor, Yu Zhigan said that he could not be confused by the illusion in front of him. Easy-to-use things need to be proved through practice.

"Su Dingfang, if you ride a horse to the outside of the city, how long does it take for the horse to run? Will there be problems with the horse's hooves?"

"When you go back to Your Highness, usually if you marche and run for a hundred miles, your horse's hooves will be damaged. It depends on the place you pass by. If it is a mountain road, it may be more serious and the grassland will be better!"

"Then let's go around Chang'an City twice to see the effect!"

"Here!"

The horseshoe has been studied, so I’m waiting to collect the money below!

Yu Zhigan couldn't help but think of several generals who bet on him. They all bet on treasures, such as the ancestral health care, the big sword, the jade pendant, etc., all of them seemed to be valuable. Then they sold the patent of the horse iron hoof to the military headquarters, or opened a workshop to specifically put the horse iron hoof on the war horse. I will definitely not short of money in the future!

What to do after having money? Yu Zhigan fell into deep thought. He was already the crown prince, his father was the emperor, and his mother was the queen. He was already below one person and above ten thousand people. Although he was bullied by Cheng Yaojin and other old men every day, he was also considered the top part of the Yu Tang Empire's power.

If you don’t lack money or power, then you can only give back to society? Do inventions and creations? Improve your quality of life? It is indeed a good choice. After all, there were no toothbrushes, no soap, and even a bath towel in ancient times...

When Yu Zhigan made a rough decision in his heart, Su Dingfang rushed back from outside.

"Is something wrong?"

"Your Highness, this horseshoe is a bit unreliable, it has fallen...!"

Two of the four horseshoes had fallen off the horseshoes. Yu Zhigan couldn't help but touch his head. Sure enough, inventions and creations require continuous practice to succeed. How unreliable it is to just say something lightly!

Yu Zhigan now wants to drag Yun Ye that guy out and ask how he did it...

"Where is that Ojiko!"

"There is the official!"

"Burn this horseshoe red, and cover it on the horseshoe!"

Ou Zhizi is a blacksmith. When he looked at the horse, he thought about the red iron piece. If the horse hurts, he will put it in one step.

"What are you doing while standing there! Go quickly!"

"yes!"

Ou Zhizi couldn't help but sigh and hardened her teeth. Sure enough, the legend is true. This Eastern Palace is the abyss. When you come in, you will...

A few minutes later, Ouzhizi trembled with the red horseshoe on the horseshoe. The horseshoe that was expected to fly in the air did not appear, and then he breathed a sigh of relief.

"If you hit the nail in again now, it shouldn't fall off!"

"good!"

After finding out that he would not be kicked, Ou Zhizi breathed a little relieved and began to get busy. Soon, all five horses were hit on the iron hoof.

"Su Dingfang, take a few people to ride around Chang'an City to see if there is any problem!"

"Here!"

In the Wei Palace, Yu Tai couldn't help feeling a little pleasant when he looked at the horses that had been hoofed and stepped on the bluestone slab!

"I rode this horse into the palace. I must hurry up to the prince Zhigan and present the horse's hooves to my father!"

"Second Your Highness, let's give it a try first!"

"good!"

Yu Tai rode a horse and walked around the Wei Palace for a few times, but found nothing wrong. He even threw the blade on the ground. The horse's hoof was injured. After asking the groom, the horse's hoof could indeed protect the horse's hoof, so Yu Tai was more confident!

"Qin Hui, send someone to the palace to report the good news, and I will arrive later!"

"Here!"

Yu Taizhi patted his mount perfectly, and he was already filled with joy. Brother, brother, although it was invented by you, I made my contribution first, and this credit is mine!
Chapter completed!
