In fact, the protection principle of the horseshoe, that is, the horseshoe is very simple, the horse's hooves are composed of two layers, and the layer that comes into contact with the ground is a layer of hard keratin about two to three centimeters thick, and the upper layer is * keratin.

The horse's hooves are in contact with the ground, and they will fall off quickly due to the friction of the ground and the corrosion of the water. The use of horseshoes not only protects the horse's hooves, but also makes the horse's hooves grip the ground more firmly, which is beneficial for both riding and driving.

Thinking of this, Li Yuanba looked at Blacksmith Zhao with some unwillingness, made his last effort, and said, "You really haven't heard of horseshoe?" ”

Blacksmith Zhao's expression was very confused, he looked at Li Yuanba, and then at Bai Fu, who was standing not far from him, and finally said to Li Yuanba with certainty:

"Lord Wang, if this thing is to protect the horse's hooves, the small one has never been seen before!"

“……”

Li Yuanba was speechless, the kind that was very speechless.

"Lord Wang, if you can design a sketch, the small one ...... The small ones should be able to be made! ”

Blacksmith Zhao looked at Li Yuanba very seriously and eagerly, if this thing is really used to protect the horse's hooves, then it must be an epoch-making thing.

"Bai Fu, where is the nearest blacksmith shop to the palace?"

Li Yuanba turned his head, looked at Bai Fu and said.

Bai Fu thought about it, suddenly his eyes lit up, and said:

"Lord Wang, before your wedding, in order to renovate the keel, we once specially built a blacksmith workshop and made a lot of metal nails and rivets. Until after your wedding, the blacksmith's workshop was left unused. ”

"Oh? But the king forgot! ”

Li Yuanba was stunned for a moment when he heard this, and then he remembered. This blacksmith workshop was deliberately not dismantled by themselves, so that when they needed something in the future, they could have someone help build it at any time.

"Let's go, go to the front yard!"

The blacksmith's workshop was in the small east house in the front yard, and it was fueled by coal. This brand new blacksmith furnace is also slowly taking over the blacksmith world in Chang'an City.

……

When the time had passed, Li Yuanba ordered Cheng Fu to go to the Xuanwu Gate Shenwuwei camp with his warrant, and told them to postpone the expedition by one day.

As for Cheng Biting Jin's army, it had already been drawn as early as when he first entered the Chen.

The front yard of the palace, the blacksmith's workshop.

Two young blacksmiths. Sitting in front of the blacksmith's workshop and chatting.

"Big brother, we've been here for more than 20 days, right? Except for a few days ago, I hit a large number of rivets, and this will be idle for another three or four days, and it's not a thing to stay like this all the time? ”

A stocky-looking young man with a large bowl in his hand. He took a sip of hot water and said.

The other young man, who looked about the same as the young man before, but was a little older, glared at the young man angrily, and said:

"Xiaofei, why are you complaining? We work in this palace for a day, and the prince gives us a tael of silver every day, such a good job. I can't find it with a lantern, you stinky boy is still complaining......"

The young man named Xiaofei was just about to speak, but suddenly noticed four or five people walking not far away. The one in the middle looked familiar, and couldn't help but widen his eyes and said, "Alas...... Big brother, you, do you see if that is the prince......"

"What prince is not the prince, let's come...... King, king. Rajah! ”

The young man glanced at Xiao Fei with some impatience, and when he looked up, he just happened to look at Li Yuanba. I couldn't help but open my mouth and stutter.

"Hmmm! This king remembers you, your name is Gu Peng, right? Li Yuanba bowed slightly to the two little blacksmiths. said: "Your name is Gu Fei? ”

"Yes, Lord Wang, you, do you remember the little one?"

When the two brothers heard Li Yuanba call out their names, they suddenly became inexplicably excited.

"Hahaha, don't be nervous, this king is here today to trouble you!"

Li Yuanba laughed, stepped forward and patted the shoulders of the two, and then pointed to the blacksmith Zhao behind him, and said:

"Two, this name is Zhao Hansheng, he is one of the best blacksmiths in our Chang'an City, you have to be closer and closer in the future!"

The two little blacksmiths had obviously heard Zhao Hansheng's name, and hurriedly saluted him: "Master Zhao......"

"Your surname is Gu? Who are you, Gu Qiu? Zhao Hansheng picked up the two young men and asked.

"It's my father!"

The Gu brothers looked at each other in surprise and said.

"It turns out that Brother Gu is the father of the two of you, and your father and I are the same grandfather, so you two will call me Uncle Zhao in the future!"

Zhao Hansheng suddenly became happy when he heard this, and pulled the two brothers to look up and down, left and right.

"Yes, Uncle Zhao!"

The famous blacksmith master in Chang'an City turned out to be their uncle, which was definitely not a small shock.

"Yo, I didn't expect you to be relatives!" Li Yuanba patted Zhao Hansheng on the shoulder and said, "But this pro also admits it, isn't it time to work?" ”

"Ah...... Yes, Lord Wang! You see me so happy that I forget everything! ”

Zhao Hansheng reflected and dragged his two newly recognized nephews into the blacksmith workshop.

"Lord Wang, what do you say about this horseshoe?"

After lighting the blacksmith stove and pulling the bellows, Zhao Hansheng and the Gu brothers officially entered the state.

"Well, the three of you have made four iron bars so wide and so long for this king!"

Li Yuanba lowered his head and thought about it, and stretched out his hand to geek.

"Lord, we have ready-made!"

After listening to Li Yuanba's words, Gu Fei didn't say a word, and found a few iron bars from a pile of iron materials, which were about the same length and width as Li Yuanba's description.

"So, Bai Fu, you go find a few long logs, huh...... It's the kind of wood that can hit the ground! ”

Li Yuanba described to Bai Fu another four taller nail palm racks that could hold horses in place.

"No!"

Bai Fu answered very simply, and then directly ordered a few of his men to go down to the firewood room in the backyard of the palace, chop the firewood with a big knife, and quickly made four long wooden stakes.

Three were nailed into the ground, one was horizontally raised, and a very long beam was built, which was about two feet above the ground, and it looked extremely sturdy.

After making these things, Li Yuanba stretched out his hand and patted the shelf, but it was so strong, he could definitely tie Xiaobai and prevent it from moving blindly.

"Bai Fu, you go and find a ruler...... By the way, Gu Peng, Gu Fei, you two come over and bolt Xiaobai, don't tell him to move! ”

Li Yuanba gently kicked Xiao Bai's snow-like buttocks, knocking it down directly, and then commanded the Gu brothers to take a rope, tie Xiao Bai's right hind leg, and bolt it to the pillar behind, mainly not to let this thing mess with the hooves. (To be continued)
