Since Liu Han surrendered to Liu Tai, he has been raising horses in the north and working hard to cultivate the future for Liu Tai.

At the beginning, Liu Han felt that he would raise war horses, and when Cao Wei left the position of Youzhou Thorn History, he would be able to take over smoothly.

Don't look down on raising horses, in ancient times, horses were much more expensive than people, one of the servants of Jiuqing, that is, the official who was responsible for raising horses.

Even the Monkey King started from the official position of Bi Ma Wen.

Liu Tai entrusted the frontier horses to Liu Han, to some extent, paved a road to Jiuqing for Liu Han.

As long as Liu Han executes the work step by step and does not make any obvious mistakes, then Liu Han will be able to enter the position of Jiuqing in the future steadily.

At first, Liu Han also thought so.

It's just that after he really started taking over these tasks, he found himself in a big hole.

Because Liu Tai's plan to transform the alien race was sent to him, let him try it.

Then, Liu Han tried, and the whole person fell into it, and some couldn't climb out.

Because Liu Tai's plan is to help the alien race to overdevelop from nomadic herding to animal husbandry, and strive to change the way of life of the alien race in the north.

Help them learn to cultivate pasture grass, wheat and barley, so that they have a unified place to live, it is better to learn to build a city wall, a unified life, instead of chasing water and grass to live, Liu Tai wants to send troops to fight, I don't know where I will get lost.

Liu Tai held high the banner of sinicization, but it does not mean that if he registers his name on the household register, he can become a Han Chinese.

Liu Tai must be a foreign race and be assimilated into a Han Chinese, so he must have common living habits, a common Wenhua inheritance, and blood compatibility and so on.

It is impossible to say that one is a nomadic who lives after water and grass, and the other is a Han common man who cultivates the fields.

Even if Genghis Khan has Liu Bang's blood, he is the same as the Mongols in the end, and what he hopes is not that the Han people will be changed by the grassland, but that the Han people will change the way of life of other races.

Under such circumstances, Liu Tai asked Liu Han to start this attempt.

To be honest, Liu Han thought Liu Tai was crazy when he got the plan, but even if Liu Tai was crazy, what if he was his top boss, Liu Han followed Liu Tai to discuss in detail for a long time, and then took this theoretical system to the north to try.

Liu Han first communicated with Zhao An, who drew a circle on the land north of Youzhou and personally communicated with the local Xianbei tribe.

These Xianbei tribes were soon moved to the Coal Division, which was still managed by Xi Jian at the time, to dig coal for the Han Dynasty.

They did their part to establish a new Han dynasty with Han people as the main body and the coexistence of multiple ethnic groups in China.

As for the Xianbei people in this land, the Duan Xianbei clan fought with the Murong clan in Liaoxi, and Tuoba Xianbei was divided into two departments to fight inwardly, so there was really no time to come forward to call the shots for these Xianbei people.

Soon after, after the Tuoba Xianbei tribe was served by Zhao An's fisherman, he also accompanied them to the coal and steel division to mine, and fought together for the cause of building a Han dynasty.

After completing the land acquisition of the pasture, Liu Han began to select forage grass seeds.

After all, there is only one sentence in Liu Tai's plan: "Let the aliens cultivate the pasture, and learn from the Han Dynasty to sow in the spring and harvest in the autumn." ”

However, there is no question of how to create pasture, what kind of grass to use for farming, and what kind of cultivation method to cultivate.

Liu Han can only rely on himself, his biggest trait is obedient, and he is serious in doing things.

With the mind of going step by step, Liu Han selected the grass that was easy to grow from the pasture eaten by thousands of foreign livestock, such as alfalfa, goose grass, purple root cabbage and so on.

Picking out these grasses, Liu Han really read poetry and books, went to read history books, and found out what kind of grass the Han Dynasty ate at the beginning, and then, whether this grass can be cultivated on a large scale.

In the end, it was the aliens who took the initiative to send purple root vegetable seeds in the second year, so that Liu Han discovered that this kind of pasture grass is not only cold-tolerant, but also drought-tolerant, does not eat land, and is loved by livestock.

The most important thing is to be able to cultivate it once and harvest it many times like a leek, which is really a high-quality feed.

As for the fact that the alien race sent this kind of fodder seed in the second year, it was because at the end of the first year, Liu Han made the green reserve according to Liu Tai's method.

Although the results were not very good, at least the animals were able to eat, and the masons built ranches in the grasslands for the livestock to spend the winter.

The animals are no longer confined to sheltered from the wind to keep warm, but the ondol can be burned with coal, so that even in winter, they can enjoy the same indoor warmth as humans.

This allows many livestock, which theoretically cannot survive in winter, to survive the winter without being slaughtered directly after freezing to death in winter.

In Huaxia, this kind of thing is mainly burned by the people to cut down and dry wood, because it is the most cost-effective for the people.

But for the aliens of the steppe, wood? It's not easy to find wood to burn in the grasslands.

Livestock manure is the most common incineration material for them, and if these things want to be stored to maintain the entire ondol running for three months until spring, even if it needs to light up the biogas technology, it is gradually squeezed out of the Huaxia market Coal ondol appeared.

The most important thing is that the coal from these coals was also excavated by those of different races who were unwilling to switch from nomadic herding to animal husbandry.

To a certain extent, it can be regarded as self-produced and self-sold, and has made outstanding contributions to the transformation of animal husbandry and nomadic herding.

If you want to turn nomadic herding into animal husbandry, this kind of herd house that can ensure warmth in winter and allow more livestock to live can only be regarded as second, and the real credit is still in the technology of green storage.

This kind of technology, which has almost no barriers, under Liu Tai's insistence and guidance, Liu Han completely got it out in the second year, and since then, the alien races in Youzhou have developed from nomadic herding to animal husbandry.

There is no other reason, because now it is getting colder and colder in the north.

If it weren't for the fact that a large area of grassland would be eaten clean soon when grazing, forcing me to chase after the next grassland, who wouldn't want to stay in one place with peace of mind and live a peaceful life!

The green storage technology allows the livestock to eat abundant food in winter, and the herding technology allows cattle and sheep to avoid freezing to death in the wind and snow.

As the nomadic aliens truly feel the benefits of these two technologies, it is natural that some of the aliens will stay, and the nomadic aliens who live after water and grass will gradually become the herding aliens who stick to a pasture to live.

Liu Han drew a circle on the map, and these alien races planted grass and grazing in this grassland, but at the same time, they also needed to plant grass and maintain it.

The most important thing is to calculate how many livestock are left for the winter each year and how much rations need to be stored.

The extra livestock will basically take the initiative to go to the county seat, and even go to Youzhou to exchange for salt and grain, and even a lot of new clothes, even war horses and other things, as well as the most important luxury tea.

It can be said that with the opening of the North Canal from Youzhou to Jinkou, this gave the northern aliens an opportunity to contact Qingzhou goods.

Let them find that through a year of hard work in raising livestock, they can exchange their living materials from the market for their own living materials for the second half of the year, or even a year, which changes the way of life of these aliens.

Under normal development conditions, even with the Qingchu system, it is very difficult to develop the alien race from nomadic herding to animal husbandry.

The north of Youzhou is not a place where water and grass are fertile in nature, but Youzhou has become different after the coal supply from the Coal Division has been vigorously supplied.

Because with the vigorous supply of coal, the life of the alien race has undergone a fundamental change.

Especially in winter, not to mention the problem of getting water, it has always been very difficult, but coal allows them to boil snow water directly when they are heating, and use this boiled and cooled snow water to give livestock and even drink for themselves.

Not only aliens, but even Youzhou, Qingzhou, and even Jizhou, although it has been so many years, Liu Tai's biggest role in the steam engine is only to play a very powerful instrument such as smashing something in the mine or trying to pump out the water in the mine, and it is still far away for the watt-level steam engine.

However, the use of coal itself is highly advocated by Liu Tai.

It is not only the use of charcoal fires for heating in winter, but more importantly, the use of productivity.

For example, it is used for forging steel, for example, simulating a constant temperature greenhouse for crops to grow, and even in the excavation canal, if there are some solid rocks that are difficult to cultivate, they are first burned with high-temperature charcoal fire, and then thrown on with cold water made of saltpeter.

There is no other way to be familiar with it, and this skill is used a lot, and it will naturally be mastered.

Not to mention, because of the higher toughness and strength of steel tools brought about by the high-temperature calcination of coal, the production is even faster.

It can be said that under Liu Tai's initiative, although coal has not yet been fully popularized in society after the steam engine was made, Liu Tai knows very well that the development of this society depends on the efficiency of the use of cheap and large amounts of energy.

Until now, Liu Tai had not invented a steam engine or a generator.

But as Liu Tai took the initiative to introduce coal as a resource into the re-aligned society, and as far as possible to replace those industries that used to consume manpower, but can now be replaced by energy, Liu Tai can clearly feel that the whole society is developing.

Although the speed of development of this civilization is not like the explosive development of mankind after mastering the steam engine.

However, Liu Tai felt that the entire social level had at least gradually been able to keep up with the Song Dynasty, and even if it was the Song Dynasty, there would be no emperor like Liu Tai, who advocated the development and promotion of coal resources to society.

However, no matter how much coal resources are promoted, the mainstream of this era is still livestock.

No matter how much coal resources have development potential, at least until the steam engine is invented and improved to the point that the tractor that can cultivate the land comes out, livestock power is still the most important resource, so Liu Han's opinion must also be taken seriously.

In the past, it was to conquer the north of the Yellow River, so all of Liu Han's resources were tilted towards the war horse.

Even if Zhao An took advantage of the Tuoba family rivalry and finally came to a fisherman to make a profit, he basically gave it to Liu Han to raise horses.

This is also why when Liu Tai and Shi Le competed, Liu Tai's war horses were not inferior to the number of Shi Le.

But now, as he took the land of Hebei, Liu Tai began to increase the number of cattle cultivated among the requirements given to Liu Han.

After all, now the alien race also has to farm the land, even if it is grass, it is necessary to master the intensive cultivation technology of the Han people little by little.

After all, if you want to incorporate into Han nationality, but you can't even farm, then what kind of Han are you?

As long as there is cultivated land in the north, and then the nose ring is added to the cultivated cattle, some cultivated cattle can always be cultivated, and then transported to other areas in Hebei that lack cultivated cattle, accelerating the coverage area of cultivated cattle.

After all, in this day and age, ploughing cattle can almost be regarded as the primary productive force.

When will it be implemented to one household and one cow, and I think we will be able to achieve a well-off society in this era.

Therefore, Liu Tai thought about it for a while, and decisively asked Liu Han that this year's war horses need to be slaughtered 8,000, and it is best to increase the number of war horses slaughtered every year to 15,000 in three years, and the goal is to stabilize at more than 20,000 war horses slaughtered every year.

Then it is no longer to develop in the direction of battle, but to train horses or mules that can carry more items.

In addition, the main task this year is to complete the improvement of dryland cattle, so that they can learn to reclaim the fields after the ring.

If you can plough as many cattle as possible, there is no upper limit, and if it is successfully completed, they will be used when ploughing in the spring next year.

After all, last year's main task was to defeat Shile, and all the development directions of the northern pastures were all towards war horses.

But this year, the land of Hebei has been won, so naturally, the demand for cultivated cattle is naturally geometrically increased.

Liu Tai knows very well that if the cattle can really become ploughing cattle in the northern region after the ring, then no matter how many ploughing cattle there are, the land of China can be eaten.

After all, with ploughing cattle, the efficiency of reclamation increases too much.

Even if there is a saturation of ploughing cattle in the future, the ring on the nose of the cow can be picked to become a beef cattle.

However, Liu Tai thought about it and felt that it was too far away to expect every household to eat beef cattle in the future, as long as the steam engine had not yet been invented to allow mechanical energy to replace biological energy, then for the people, cattle were much more used as productivity tools than as food!

Liu Tai also quickly replied to Liu Han and devoted himself to the construction of supporting facilities for the Grand Canal.

Liu Tai knew very well that if the Yongji Canal could not be opened smoothly, then even if Liu Han cultivated cultivated cattle, it would be very difficult to transport them to the area north of the Yellow River, and the consumption on the way would not be a small amount.

But as long as the Yongji Canal is opened smoothly, and Youzhou starts from Bohai Bay to Qingzhou is a road, and Yongji Canal is a road, then at least the essence of the entire North China Plain will be indispensable from now on.
