"Let's leave the matter to Wu Xin and Liu Yan to handle it. Anyway, Sima Bao from Qinzhou will not be able to make any trouble without Zhang Zhi's support."

Liu Yu has now controlled the Northern Central Plains, and what he needs most is the results he has digested, and he is not in a hurry to attack Longxi and Yizhou.

This strategy was also repeatedly discussed with Xi Jian, Gongsun Sheng and others.

"It is really a blessing for the people to be not arrogant or impatient."

Although Xi Jian's ancestors were once rich, he thought that during the Yongjia period of the Western Jin Dynasty, he was already poor and destitute, which was no different from ordinary refugee commanders.

Such a background naturally made Xi Jian very clear about the importance of letting the people recuperate.

"I only need to give me three years to wait until the food and grass is abundant and then take over Yizhou, and it will be easy to get it."

Liu Yu said confidently.

There are a large number of Guanzhong refugees in Yizhou, and there are more than 20,000 and more than 100,000 refugees in Hanzhong alone.

There are almost the same number of refugees in Yizhou south of Hanzhong.

Under the command of Li Xiong, the Di people, these people once had a brief opportunity to recuperate in Yizhou.

However, since Li Xiong became emperor, the area in Liangzhou to the south and Ba County to the east has not been stable.

In order to deal with these Jin troops that surrounded him, Li Xiong gradually began to exploit the people under Yizhou.

In addition, the comfortable environment in Shu has been around since ancient times. Once Liu Yu launches a large army to attack, Li Xiong's internal internal will most likely explode.

"Your Majesty, now all the prefectures and counties in the Central Plains have placed a large number of refugees to restore farming. The imperial court has long been insufficient for plowing oxen in each prefecture. This year's spring plowing is already lacking, resulting in many wasteland not being cultivated. The autumn harvest and autumn planting are about to come, and I'm afraid there will be even less plowing oxen."

Xi Jian suddenly said.

Since the Huns were pacified, the duties of Xi Jian and others were no longer simple military advisers.

Each of them became Liu Yuqin's official officials who supervised the farming affairs. None of them all assigned several prefectures and counties to personally supervise farming.

"I already know the lack of oxen."

"The ox is already slow to reproduce. If you want to expand the ox on a large scale, it will probably be too late."

In this era, oxen are as important as land for production materials.

It can even be said that when there is no shortage of land, plowing oxen is far more important than land.

"However, if you don't have oxen, you can also use horses to plow the fields."

Liu Yu said.

"Use horses to cultivate the fields?" When Xi Jian heard this, he immediately felt that this method was a bit unreliable.

If it were an ordinary family, they might not know the difference between oxen plowing and horse plowing, but Xi Jian had once taken refuge in the mountains and fields and was very clear about farming.

"Your Majesty, this horse is not as oxen as its endurance, and it is easy to damage the horse's hooves, and it is difficult to replace the plowing oxen."

"If you are not as strong as a cow, then use two horses. If two horses don't work, then use three horses." Liu Yu said indifferently.

"How many horses do you need?" Xi Jian opened his mouth wide in surprise.

"Now Qianghu, Suotou, and Hunto are about to surrender. It's not a trivial matter to want tens of thousands of horses."

Liu Yu smiled and continued.

"And those horses used to make plowing horses are generally not allowed to be war horses, and they do not conflict with my plan to expand cavalry."

"But horses are prone to damage their hooves, not to mention that they are in gravel and muddy fields. I am afraid that the horse's hooves will be scrapped after not long after they are plowed."

Xi Jian immediately expressed his doubts.

This horse's hoof is much weaker than a cow's hoof. Even when riding normally, you must pay great attention to the maintenance of the horse's hoof.

Once you get into the muddy fields, you will be destroyed soon.

"Haha, I have already ordered someone to solve this matter." Liu Yu smiled proudly.

"Hmm? How to solve it?" Xi Jian looked puzzled and curious.

"Xi Qing follows me!"

After Liu Yu said that, he got up and walked out of the hall with Xi Jian.

When he turned to the other courtyard in the palace, Xi Jian saw several horses in the courtyard galloping happily.

"Your Majesty, why do these horses have the sound of iron and stone when they run?"

Xi Jian had already noticed the unusualness.

When these horses ran on the brick and stone floor, they made the sound of tinging iron tools hitting.

"That's because these horses are wearing iron shoes."

Liu Yu said as he took an iron arc object from the eunuch next to him.

If anyone in later generations would recognize it at a glance, it was a horseshoe.

"Iron Shoes?" Xi Jian took it and looked at it, and his face immediately became extremely serious.

"I think this thing is called a horseshoe." Liu Yutian said shamelessly.

"With these improved harnesses, it should be no big problem to use two horses to hold a cow."

"Although horses need to be replenished when ploughing, there are many wastelands now. As long as you buy a variety of Western alfalfa from Liangzhou, ten acres of alfalfa can be used to supplement the horse's fine material for ten acres. Although it is not as safe as plowing oxen, it is worse than carrying it on the shoulders of people."

Liu Yu said while leading Xi Jian to observe the new things he ordered to tinker with.

In today's Han Dynasty, almost everyone in Yecheng knew that today's emperors do not like silk, bamboo, singing, dancing, or acting, or prostitutes, but prefer various clever tools.

Everyone rumored each other that the emperor of the dynasty wanted to promote the Mohist school of that year.

In the so-called new dynasty, many scholars who had no moral integrity began to quietly study the Mohist learning in a few words.

"Your Majesty, this horseshoe is absolutely not usable."

Just as Liu Yu introduced with a happy expression, Xi Jian next to him suddenly said with a serious expression.

In other words, the expression on the face seemed to be quite shocked.

"Xi Qing, why did you say this?" Liu Yu was also surprised.

He really didn't understand what happened to Xi Jian.

"Your Majesty, this horseshoe can not only be used to plow the horses. If horseshoes are installed on the horses in the world in the future, the barbarians in the north will have the capital to rush to a thousand miles."

Xi Jian said worriedly.

"In the past, even if the barbarians wanted to run a thousand miles, they would often have to go for a long time, just to maintain their horse's hooves. If they had this horse's hooves, the barbarians in the vast grassland could roar and would no longer be afraid of the wear and tear of the gravel and soil, and there would be a disaster."

After Xi Jian said that, he looked at Liu Yu with a worried look on his face.

Seeing this, Liu Yu couldn't help but sigh.

This Xi Jian really has an unusual vision.

He was just talking about the protection of horseshoes on plowing horses, and he immediately thought of military innovation purposes. It was really amazing.

"Xi Qing is indeed a mature country plan, and what he said is really reasonable."

"However, I've already thought about this."

After Liu Yu said that, he raised a piece of horseshoe in his hand and continued.

"This horseshoe, even if it doesn't exist now, will still be there in the future. Instead of doing that, it's better to make it earlier and use it for cultivation first."

"As for the things that made the Hu barbarians grow stronger, to be honest, I don't care much about this."

"In fact, as long as the Central Plains are stable, they will not have any chance. It does not lie in this small horseshoe, but in the hearts of the people."

"If a person's heart is broken, no man can raise his sword or gun any better."

Hundreds of years later, the father and son of the Duke of the Great Jin Dynasty never lacked any hardware, but it was difficult to resist the Jurchens.

"What does Your Majesty mean?" Xi Jian was a little confused.

"This horse farming is a great thing that benefits the country and the people. As long as there are demands for this large number of horses in the Central Plains, we can choose and breed better horse breeds." Liu Yu said.

"This horse breed is getting better and better. Maybe at any time, there will be a horse that is comparable to the plowing ox."

Heavy horse pulling has always been a scarce material in East Asia.

This powerful horse-drawn horse is an important guarantee after the establishment of the modern military logistics system.

Without these heavy horse-drawn horses, the strict material support needed by modern military forces would be difficult to meet.

Therefore, Liu Yu felt that he should choose and give it a try.

"There is one thing that Your Majesty may not know." Xi Jian said in a bad mood when he saw Liu Yu being in high spirits.

"What's the matter? Xi Qing just said it's okay." Liu Yu said indifferently.

"Everyone in the world knows that this horse is a powerful weapon of the country. Once a war breaks out, it is often recruited to recruit the people's horses to serve as troops. No matter whether the money and food are given or not, the horse will lose a great help once it leaves, and often needs to reduce production. If the plunder slaves are in danger, there will be no recruitment. I am afraid that the people will not want to raise horses."

What Xi Jian said is very reasonable.

Afterwards, Xi Jian talked about the horse raising in the north since the end of the Han Dynasty and the Three Kingdoms.

It turned out that the Central Plains also became popular on large-scale horse raising, but with the outbreak of war, the first people who suffered losses were the first to suffer.
