On the horse farm.

"Hi, Li Cunxin!"

A gust of wind blew past Li Cunxin and the black wind, blowing Li Cunxin's hair and snorting.

"Li Cunxin, I'm here again."

"Smack!"

Li Cunxin threw the horsewhip to the ground and looked at Qin Han who was leaving.

Just now, Qin Han pulled Ah Chai to slip on the horse farm for a while, and Ah Chai actually regained his vitality and began to run.

Li Cunxin and the horseman's eyes fell to the ground, looking at the figure that kept galloping on the horse farm, where was the Ah Chai who had to walk out of the horse shed for a while.

Since he slapped his hands, Li Cunxin still kept his promise.

Ever since they had ice, the two of them have been drinking ice wine. However, only wine is suitable for ice, and other liquors are more comfortable to drink hot. However, most of the Li family's wine is an annual tribute in the palace, and even Li Ding is not very willing to drink it. It's okay once or twice, but if there are too many times, it will inevitably be discovered, and Li Cunxin is ready to be beaten. I thought that Qin Han would let him take some more wine out of the house, but he didn't expect Qin Han to shake his head and deny it.

Just let Li Cunxin pull the black wind and stand by the racecourse, no matter what happens, he is not allowed to move.

When Li Cunxin heard this, his eyebrows immediately fluttered, what is this, isn't it just standing, standing for a day is not a problem.

Li Cunxin nodded in agreement, Qin Han didn't say anything, just couldn't stop laughing.

Maybe Ah Chai knew that Qin Han helped him, and he was very obedient to Qin Han, Qin Han gently stroked Ah Chai, turned over on the horse, looked at Li Cunxin, who was still stunned, and smiled.

"Hehe, face the wind!"

……

Li Cunxin's originally dark face had become darker, and looking at his friend's appearance, Qin Han was embarrassed to bully him again, after all, he had already found his way back.

Qin Han got off the horse and walked to Li Cunxin with his waist in his hand. In the two laps he just ran, in order not to let himself fall, Qin Han tightly clamped the horse's belly with his legs, and his spirit was relatively concentrated, it was okay when he was excited, but he felt a little tired when he got off the horse, and the two buttocks and the inner thighs were a little hot.

Ah Chai also stopped with Qin Han, and began to gasp for breath, his current body, after running so many laps, the consumption made Ah Chai a little unbearable.

Seeing that Qin Han stopped, the groom staggered over with a bucket.

As soon as the bucket hit the ground, Ah Chai leaned down and plunged into the bucket.

Looking at the rejuvenated Ah Chai, Mafu's face smiled like a chrysanthemum. Turning to Qin Han, he bowed and clenched his fists, and said.

"Childe is really talented, only eight buckets high, only five cars rich, talented, talented, wealth is not exposed, talent..."

"Okay, okay, it's all a small thing." Qin Han hurriedly waved his hand at the groom, and didn't stop him anymore, for fear that he would have to talk about the number of words.

"Don't you fix horses' hooves on weekdays?"

When he noticed Ah Chai's hooves, Qin Han was startled by Ah Chai's hooves, this was the first time he had seen a horse's hooves look like this. Immediately he had some contempt for this groom, and he was so emotional about Ah Chai's life, no, Ma Sheng said it so eloquently, but he didn't even do anything about manicures for people's nails.

"Trimming horseshoe? This... Qin Gongzi, this horse's hooves have really not been repaired, and I have never seen the horse's hooves grow like Ah Chai. ”

The groom was a little confused, his family had been a stableman for three generations, but he had never heard of repairing a horse's hooves.

Qin Han glanced at him, nonsense, there are a few horses like this, they haven't been out of the stables for so long, and they haven't run on the grassland wantonly. "Then if you don't repair the horse's hooves, how can you change the horseshoe?"

"Change horseshoe?"

"It's a horseshoe!" Qin Han's impression of the horseman took a sharp turn, and he didn't even know how to be a horseman when he changed his horseshoes. Sure enough, a family like the Li family, which has a big business, is easy to mix in with some subordinates with poor quality.

The groom was completely stunned by Qin Han's question, this horseshoe is as the name suggests, but it is still understandable, what is this horseshoe? "Qin Gongzi, this horse's hoof... Horseshoes, Xiao Lao'er has never heard of it, and Xiao Lao'er has raised horses for three generations, and he has never heard the elders in the family mention it? ”

This time it was Qin Han's turn to be confused. "Haven't heard of it?"

"yes, Xiaohan, I've never heard of a horseshoe." Li Cunxin has been dealing with horses since he was a child, knowing stirrups and saddles, but he has never heard of horseshoes.

Li Cunxin looked at Qin Han carefully, he had already inquired, Qin Han had been injured in the brain and had hysteria, he wouldn't start talking nonsense at this time, and he wouldn't be sick again.

Qin Han rubbed his chin, it shouldn't be, he is a student of history, it stands to reason that the horseshoe should have been used by the Uighurs as early as the Sui Dynasty, is it his mistake? Could it be that it is not called by this name, or has it not been passed down until now?

Although there was a deviation in the history of this world, Qin Han didn't find any deviation before Tang. Qin Han didn't believe it, and opened the hand that Li Cunxin put on his forehead.

Regardless of Li Cunxin's dissatisfaction, he picked up a dead branch, drew the shape of a horseshoe directly on the ground, and then pulled Li Cunxin over.

"Oh, that's what it looks like, have you ever seen it?"

Li Cunxin and Ma Fu squatted aside and changed several positions, and the two glanced at each other, their eyes revealing ignorance.

"I haven't seen it yet, what's the use of this?"

Li Cunxin's words made Qin Han sure that there was no horseshoe in Dajin, a horse soldier and a horseman, neither of them had ever seen each other, so it must be nothing.

What's the use? This is very useful, walking barefoot can be comfortable with shoes, and walking for a long time can not wear out feet. If you put shoes on the horse, the horse's hooves will wear a little, and you will not be able to run farther.

Qin Han scratched his head and asked. "You usually spend a lot of time in the army, do you know where the war horses in the army are spent?"

Li Cunxin thought about it and said. "If you want to talk about the cost of war horses, in addition to forage, it is the largest cost of dying in battle. Others, that is, some appliances are replaced immediately. By the way, there are also horse hooves, horses that often fight, the horse's hooves are too badly worn, once the horse's hooves are worn, it will cost a lot of silver to maintain, and it will also delay a lot of fighters. ”

Qin Han squinted his eyes, in this way, can he give a lot of silver to the imperial court by offering the horseshoe himself.

Qin Han was a little excited, his opportunity had come, to save money for the imperial court, and to help the army fight, killing two birds with one stone, although it was not as good as offering good seeds, but this was something that could see the effect immediately, and the reward would definitely be fast.

Suddenly, Qin Han looked at Li Cunxin hotly, is there any other place in the army where he can give advice, now that his family has a big business, it is not easy to have no reward from Emperor Jin.

Qin Han's eyes made Li Cunxin's chrysanthemum cold, and he couldn't help but clamp his buttocks. "Why do you think of me like that, you haven't said what this thing is for."

"What's the use? Its usefulness is great, it can almost make the war horse do not have to think about the loss of the horse's hooves, only need to change the horseshoe once a year, and nail the horseshoe, the war horse can also better adapt to various grounds, you say that the use is great. ”

Li Cunxin carefully knocked on the thing that Qin Han painted on the ground, but after looking at it for a long time, he still couldn't imagine how this thing could save money for the imperial court.

Qin Han patted Li Cunxin and said. "Don't look at it, you can't see anything, let's go get it out, and you'll know what's the use when the time comes."

……

In the west of the city, in the blacksmith shop of the old grandson.

Qin Han handed the prepared drawings to the old grandson and said. "Uncle Sun, help me lay down this thing, I want four of the same."

Old man Sun took the drawings and looked at them, and his curiosity about Qin Han became more and more serious. Why is it that every time this uncle of the Chu family comes to make something, it is strange and has never been seen before.

"This needs a mold, Childe needs to wait, let Xiao Lao'er make a mold."

Qin Han nodded and said. "That's fine, by the way, this thing is about the size of a horse's hoof."

The old grandson went to make a mold, leaving the eldest son to keep pulling the bellows, the bellows were blowing the fire, and the molten iron in the pot was not bubbling twice.

As soon as the bubble cracked, Qin Han hurriedly hid away, he was so handsome, what should he do if he accidentally burned a scar.

Old man Sun's speed was still as fast as ever, and it didn't take long for the mold to be ready.

Old man Sun skillfully scooped out a large spoonful of molten iron from the large stove with a crucible and poured it into the mold. Wait for the molten iron to cool down, turn into iron, and knock the mold. I put it in the water, and when I snorted, a puff of water vapor floated.

Old man Sun took it to the stage again and began to thrash.

"Childe, it's done, take a look."

Qin Han looked at the four horseshoes, and there was basically no difference from what he had seen, but the iron looked a little worse.

"Good!"

……

Chiang Guogong's Mansion.

Qin Han stood outside the door a little apprehensively, Li Cunxin patted Qin Han and said. "What are you afraid of, it's not like you haven't seen my father, go."

Qin Han wanted to offer a horseshoe, it was impossible for him, although he had already seen Emperor Jin, but he was not familiar with it. And it's a little inappropriate to make a rash offering. And Li Ding is undoubtedly the best candidate for the middleman.

Qin Han exhaled a long breath and walked in with his chest straight.

In the hall, Li Ding was sitting at the head of the seat drinking tea. The corners of his eyebrows are full of sadness that can't be concealed, the border war is becoming more and more tense, the Khitan is not dead, and now there is not much time for such a stable time.

"Dad, I'm bringing Qin Han to visit you." Before Li Cunxin entered the door, the voice entered the hall.

Qin Han? Looking at the two people who came in, Li Ding's gaze fell on Qin Han. At first, he only knew this person because of Li Cunxin, but later at the banquet, this son spoke amazingly, and His Majesty and himself were amazed.

Later, I heard His Majesty say that this person gave a good seed with a yield of 300 stones per mu, because Xin'er had a good relationship with him, and was also sent to Tuntian together, so he received his favor, and I don't know what he came for this time.
