Dahan's grain output is increasing year by year, but the problem of food shortage is becoming more and more serious.

There are all kinds of problems, and there are many people who engage in fire dragon burning warehouses in remote places, but those are all small problems that are not worth mentioning.

There is only one real core reason, and that is a massive explosion of population.

Since the poll tax quota, the enthusiasm of the people to have children has been stimulated.

Every time there is an additional child in the family, there will be a large amount of income, and there will be one more laborer and one more bride price income.

Compared to these, family affection and everything have to come later.

Driven by huge interests, there is no need for the government to persuade and guide, and the people themselves are frantically giving birth.

When Li Yunze first ascended to the throne, the whole world was counted as slaves, and even with the addition of those wild people in the deep mountains and old forests, there were only a population of more than 40 million.

Twenty years later, after the army went out of the plough court and swept the caves, and destroyed the Xiongnu in one fell swoop, the population had directly exceeded 10,000.

At that time, the Han Dynasty cultivated a large number of new acres of land and innovated its cultivation capacity, which increased the yield and barely supported the demand for food.

No matter how much it can be increased, it is also the level of productivity in the agricultural era.

After the large-scale war of exterminating the Hungarian population, the mode of having children was started again, and the same family started with five or six children.

This exponential population growth is already beyond the upper limit of Dahan's existing grain production capacity.

As this problem became prominent, some people in the DPRK and China proposed to Li Yunze that the population growth rate of the non-governmental sector should be restricted.

Li Yunze's response was very simple: "How many people are in your family?" ”

The man responded, "There are 16 wives and concubines in the family. ”

Li Yunze followed and said, "Then start with your family, how about your children not being allowed to have children?" ”

The man was anxious on the spot, "Why!?" The children of the minister's family still have to pass on the ancestry, why not let them be born! ”

Li Yunze smiled and waved his hand, signaling the palace guards to send his entire family to a deserted island overseas.

Since it cannot be suppressed by itself, and the productivity of the agricultural era cannot be increased on a large scale, the only solution is to go out.

Expansion, migration. Expand, migrate!

Liu Yu's Korean state received a huge number of people because of his occupation of the Savage Islands.

Although the islands are not highly developed, the land is extremely fertile, as it is full of volcanic ash geology, rich in minerals, and extremely productive farmland.

Therefore, after leveling the wild people on the island, a large number of Han Chinese took a boat to the archipelago and took over the original farmland reclaimed by the wild people.

However, compared to the rapidly growing population of Dahan, this is only a drop in the bucket.

In the northern prairies, there are also a large number of Han people pouring into them to beg for a living.

From the Monan Metropolitan Protectorate, to the Grassland Metropolitan Protectorate, from the Beihai Metropolitan Protectorate to the Mobei Metropolitan Protectorate, a large number of people have poured in.

It's just that outside of the Hetao, Li Yunze has limited the number of migrants to other places.

This is naturally not because Li Yunze wants to leave room for the tribes on the grassland to live, so that they have the opportunity to develop again and threaten Middle-earth.

Purely because he knows what he knows.

Although the area of the prairie is huge, it looks like there are many grasslands.

But in fact, outside of the Hetao area, most of the steppes belong to desertified geology.

The pastures were cleared, and a few hoes could not dig half a meter deep, and you could see the sand below.

Once large-scale land reclamation is carried out, the only result is rapid desertification, followed by a series of geological problems such as sand and dust storms and land degradation.

Therefore, Li Yunze forbade cultivation on the grassland, and only allowed grazing.

Moreover, there is a quota for the livestock capacity of each pasture, which is not allowed to be exceeded.

At the same time, cattle grazing is encouraged, and the number of sheep is reduced.

Compared with cattle, sheep that directly gnaw away the grass roots when grazing have greater damage to geology and are prone to desertification.

Therefore, the prefectures everywhere limited the number of migratory people, and at the same time built cities and roads, and designated pastures in various places, and nomadism was not allowed.

If the population is too large, they will also move out of the family.

Li Yunze knew very well that once the grassland was reclaimed without restraint, after more than a hundred years, the Han Dynasty would face trouble from the north again.

As for the remaining tribes on the grassland, Li Yunze naturally migrated them all.

No matter how big or small, as long as it is a tribe encountered by the Han army, they will all be migrated away.

It was transported to the edge of the sea, and then sent to various small islands that Hermes-Epitek did not want to go to.

Under the combing of the Han army's iron cavalry over and over again, all kinds of large and small tribes on the prairie, whether they are in the south or north, have all become island tribes, and then only the grazing Han people are left on the entire prairie.

They are pure Han herdsmen, living near the designated city for grazing, and have household registration, identity and pasture.

Wei Qing, Huo Quzhi and others have been using troops to the west for many years.

First, he defeated Wusun, who wanted to submit to the Han Dynasty, and then swept through the countries of the Western Regions, deposing its king and seizing its land.

The Wusun people really wanted to surrender to the Han Dynasty, because they were frightened by the terrifying combat power of the Han Dynasty.

So strong, so terrible Huns, was wiped out by the Han people who cut melons and vegetables, as the former little brother of the Huns, how could the Wusun people not be afraid.

But the Han didn't want any vassals at all, because Li Yunze knew very well the temperament of these nomadic tribes.

When Middle-earth is strong, it is no problem to be a son or a grandson.

But once Middle-earth is weakened, they will do all kinds of evil!

In that case, let's tackle the root cause.

Wei Qing and Huo Quai, with tens of thousands of elite cavalry, took two years to level Wusun.

It's not that the Wusun people are strong enough to resist for two years, but they are too good to run.

didn't fight with the Han family at all, just ran away frantically all the way.

In the end, Huo Qubing chased all the way to the north of the distant Jinshan, which was already the place of a certain Rus country in later generations, so he caught up with the old camp of the Wusun people's royal court, and ended his royal court in a war, which pacified Wusun.

If the Xiongnu were running around so frantically, the Han would have to drag on for a few years if they wanted to destroy the Xiongnu.

The territory of the Wusun people was set up as the capital of Jinshan, and counties were set up to build city roads, and the migrating population became designated herdsmen.

It's just that this migrating population is not worth mentioning compared to the growing number of people in the Han Dynasty.

Therefore, the Han army almost did not stop, and once again sent troops to sweep through the countries of the Western Regions.

Everywhere Pingding, counties would be set up to migrate the locals, and most of the young and strong people were requisitioned to build the Han Straight Road, which ran through the entire Western Regions, and then allocated land to the people who migrated from the Han family.

For example, there are seven or eight counties around Lop Nur, and tens of millions of people live.

The fertile land on the north and south sides of the Tianshan Mountains is full of people from all over Middle-earth.

However, this is still not enough.

A large number of Han troops followed the Han Straight Road all the way to the west, crossed the Pamir Plateau, first leveled the Dawan Kingdom left over from Alexander's Eastern Expedition, and then stormed the Dayue Clan, which occupied the two rivers.

When fighting the Great Wan Kingdom, they put up a standard Macedonian phalanx to face the battle.

Wei Qing, who led the troops to attack, urged the formation with a strong crossbow and broke through his formation with heavy armor.

The First World War crushed the so-called Macedonian phalanx.

In later generations, there were always people who advocated that when Alexander went on an expedition, he hit the Qin state, which was without military common sense.

There are strong crossbows in the Han land, and those Macedonians who only wear short armor can defend themselves.

As for the spears they used, there was no chance of winning against the Han family's halberd.

Not to mention the cavalry, the cavalry of the Greeks has always been known for its weakness.

As for the Da Yue clan, they couldn't defeat the Huns back then, and now they naturally can't defeat the Han army that destroyed the Huns.

After several years of tug-of-war, it is natural that the strength will be exhausted, and it will collapse and decompose, scattered on a huge territory.

The Han army did not spend much energy to exterminate these small tribes, but went south with all its might.

Li Yunze's purpose is obvious, that is, to come to the Indian region, which has a large number of mature fields and is very suitable for agricultural civilization.

During this period, the region of India had been conquered by the Aryans who had invaded from the northwest, and a hierarchy had been established.

This was followed by successive invasions by the Persians and Alexander, and the whole of India was in chaos until the emergence of the Mauryan Empire.

Decades ago, with the weakening of the Mauryan Empire, the Dawan Dayue clan and others continued to move south, and a period of chaos began.

Without the Han army, the Otsuki clan would have occupied most of India, thus establishing the Kushan Dynasty, one of the four classical empires.

But with the advent of the Han army, everything was different.

The Han army had never encountered such a weak opponent, and they were even a little uncomfortable at first.

When they adjust, it's a direct sweep.

A large number of Han people poured into South Asia from the Western Regions and from the Dian Kingdom along the Han Straight Road, where the fertile land and abundant rainfall successfully accommodated the massive migration of people.

At the same time, Dahan's sea ship business has also continued to grow and develop with the continuous support of Li Yunze.

Strongholds and cities have been established in various parts of the South Seas, and the extermination of wild people by migratory populations and the burning of forests to reclaim fields have become large-scale and institutionalized.

He traveled all the way south and found the Sealand continent.

Of course, at this time, the Sealand continent was extremely barren, and there were all kinds of strange creatures except for the savages.

The Han family did not go deep into it, except for building a stronghold in the coastal area suitable for habitation here and planting the banner of the Han Dynasty.

By this time, the Han family's large-scale expansion had finally come to a halt, and for many years it had been busy digesting these territories and expanding the road system.

When Li Yunze was on the throne for 60 years, a generation of famous generals such as Wei Qing and Huo Quzhi fell one after another.

And Li Yunze himself looked at the huge map that was hung up and sighed lightly.

"I've done enough for Dahan!"

Later Han history has a record of 'When Emperor Wu of the Han Dynasty ascended the throne for 60 years, Chan was conceded to the crown prince Liu Xiu. After traveling the world, he disappeared. ’
