The heavens start from saving Daming

The grain output of Han Dynasty increased year by year, but the problem of food shortage became more and more serious.

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

There is only one real core reason, and that is the large-scale population explosion.

Since the introduction of the poll tax quota, people's enthusiasm for having children has been aroused.

Every additional child in the family will bring in a large amount of income, as well as an additional labor force and an additional income from betrothal gifts.

Compared with these, family love and other things have to take a back seat.

Driven by huge profits, the people themselves are frantically giving birth to children without the need for persuasion and guidance from the government.

When Li Yunze first came to power, the population in the world was just over 4000 million including slaves and even the savages living in the mountains and forests.

Twenty years later, after the army went out to sweep the caves and wiped out the Xiongnu in one fell swoop, the population had directly exceeded tens of millions.

At that time, the Han Dynasty reclaimed a large number of new acres and improved farming capabilities, which increased production and was barely able to support the demand for food.

But no matter how much it increases, it will still be the level of productivity in the agricultural era.

After the Hungarian War, the large-scale young population started to have children again. Similarly, every family started with five or six children.

This exponential population growth has exceeded the upper limit of the Han Dynasty's current food production capacity.

As this problem became more prominent, someone in the DPRK and China proposed to Li Yunze that the private population growth rate should be limited.

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

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

Li Yunze then said, "How about starting from your home? Your children are not allowed to have children?"

The man became anxious on the spot, "Why!? The children in the minister's family still want to carry on the family line, why shouldn't they be born!"

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

Since it cannot be suppressed on its own, and productivity in the agricultural era cannot be improved on a large scale, the only solution is to go outward.

Expansion, migration.Expand and migrate!
Liu She's North Korea received a huge population migration because he occupied the Savage Islands.

Although the development level of these islands is not high, the land is extremely fertile because they are all volcanic ash geology, rich in minerals, and the yield of farmland is extremely high.

So after pacifying the savages on the islands, a large number of Han people took ships to the islands and took over the original farmland cultivated by the savages.

However, compared to the rapidly growing population of Han Dynasty, this is just a drop in the bucket.

On the northern prairie, a large number of Han people also poured into them to make a living.

From the Monan Protectorate to the Grassland Protectorate, from the Beihai Protectorate to the Mobei Protectorate, a massive population has poured in.

Except for the Hetao area, Li Yunze restricted the number of migratory people in other places.

This is naturally not because Li Yunze wants to leave living space for the tribes on the grassland and give them the opportunity to develop again and threaten Middle-earth.

Simply because he knows the relevant knowledge in this area.

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

But in fact, outside the Hetao area, most of the prairie is desert geology.

When those pastures are reclaimed, the sand below can only be seen with a few hoe digs to a depth of less than half a meter.

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

Therefore, Li Yunze prohibited reclamation on the grassland and only allowed grazing.

Moreover, the livestock capacity of each pasture has a quota, and it is not allowed to exceed it.

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

Compared with cattle, sheep that eat grass directly to the roots cause greater damage to the geology and can easily cause desertification.

Therefore, the governor's offices in various places restricted the number of migratory people, built cities and roads, designated pastures everywhere, and did not allow nomadic herding.

Once the population becomes too large, families will migrate out.

Li Yunze knew very well that once the grasslands were reclaimed without restraint, more than a hundred years later, the Han Dynasty would face trouble from the North again.

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

No matter how big or small, all tribes encountered by the Han army migrated away.

They were transported to the sea and then sent in batches to various small islands where the Han people were unwilling to go.

Under the repeated sorting by the Han army's cavalry, all kinds of tribes on the prairie, no matter in the south or north, that could not even explain their origins, had all turned into island tribes. After that, there were only Han people grazing herds.

They are pure Han herdsmen, living and grazing near designated cities, and have household registration, status, and pastures.

Wei Qing, Huo Qubing and others continued to send troops to the west for years.

First, he defeated Wusun, who wanted to submit to the Han Dynasty, and then swept through the countries in the Western Regions, deposing their kings and seizing their territories.

The Wusun people really wanted to surrender to the big man, because they were frightened by the big man's terrifying fighting power.The Huns, who were so tyrannical and terrifying, were destroyed by the big men like chopping melons and vegetables. As the former younger brothers of the Huns, how could the Wusun people not be afraid?

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

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!
If this is the case, then solve the problem at its source.

Wei Qing and Huo Qubing, with tens of thousands of elite cavalry, spent two years defeating Wusun.

It's not that the Wusun people fought so hard that they could resist for two years, but they were really good at running away.

He didn't fight with the Han family at all, he just ran away like crazy.

In the end, Huo Qubing chased him all the way to the far north of Jinshan Mountain, which was already a place of a certain Rus' country in later generations. Only then did he catch up with the Wusun people's Wangting old camp, and captured their Wangting in a battle. Wusun was pacified.

If the Xiongnu were running around so crazily back then, it would have taken several years for the Han to destroy the Xiongnu.

The territory of the Wusun people was set up as the Jinshan Protectorate, counties and counties were set up to build city roads, and the population was relocated to become designated herdsmen.

It's just that this small migrating population is nothing compared to the growing population of the Han Dynasty.

Therefore, the Han army had almost no rest, and once again sent troops to sweep across the countries in the Western Region.

Every time a place was pacified, prefectures and counties were set up to relocate the locals. Most of the young people were recruited to build the Hanzhi Road, which ran through the entire Western Region, and then allocated land to the people who migrated from the Han family.

For example, Lop Nur is surrounded by seven or eight counties, home to tens of millions of people.

The fertile lands on the north and south sides of the Tianshan Mountains are dotted with people from all over the Middle Earth.

However this is still not enough.

A large number of Han troops marched westward along the Han Straight Road, crossed the Pamir Plateau, and first pacified the Dawan Kingdom left over from Alexander's eastern expedition, and then stormed the Da Yuezhi who occupied the two rivers.

When they attacked Dawan, they set up a standard Macedonian phalanx to fight.

Wei Qing, who led his troops to attack, used powerful crossbows to activate the formation and used heavy armored infantry to break the formation.

This so-called Macedonian phalanx was destroyed in one battle.

There are always people in later generations who advocate that Alexander did not have any common sense in military affairs when he defeated the Qin State during his expedition.

There were powerful crossbows in the Han Dynasty. How could the Macedonians, who only wore short armor, be able to defend themselves?

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

As for the cavalry, let alone that. The Greek cavalry has always been known for being weak.

As for the Da Yuezhi, they couldn't defeat the Xiongnu back then, and now they are naturally unable to defeat the Han army that destroyed the Xiongnu.

After several years of tug-of-war, it was natural that all its strength was exhausted, and it collapsed and decomposed, spreading over a huge territory.

The Han army did not spend much energy to wipe out these small tribes, but went all out south.

Li Yunze's purpose is obvious, which is to come to India, which has massive mature fields and is very suitable for farming civilization.

During this period, the Indian region had been conquered by the Aryans who invaded from the northwest and established a hierarchical system.

Then came the successive invasions of the Persians and Alexander, and the whole of India was in chaos until the emergence of the Mauryan Dynasty.

Decades ago, with the decline of the Mauryan Dynasty, the Dayue clan of Dayuan and others continued to move south, and a period of chaos began again.

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

But with the appearance of the Han army, everything changed.

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

When they adjust, it will be a direct sweep.

A large number of Han people poured into various parts of South Asia from the Western Regions and Dian Kingdom along the Hanzhi Road. The fertile land and abundant rainfall here successfully accommodated the massive population migration.

At the same time, Dahan's shipping business continued to develop and grow with Li Yunze's continued support.

Strongholds and cities have been established all over Southeast Asia. The migratory population has eliminated the savages, and the burning of forests and land reclamation has become large-scale and institutionalized.

He even went all the way south and found the Zealand continent.

Of course, the Zealand continent at this time was extremely desolate, with all kinds of strange creatures besides savages.

Apart from building a stronghold in the coastal area suitable for habitation and planting the flag of the Han Dynasty, the Han family did not go deep into it.

At this time, the large-scale expansion of the Han family finally came to a halt, and they were busy digesting these territories and expanding the road system for many years.

When Li Yunze took office for 60 years, famous generals such as Wei Qing and Huo Qubing died one after another.

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

"I've done enough for a big man!"

Later Han history records that when Emperor Wu of the Han Dynasty ascended the throne for 60 years, he abdicated to Prince Liu Xiu.After that, he traveled around the world and disappeared. '
