Lu Tianlong pondered for a moment: "Back to my father, my sons feel that we should follow the strategy of the grassland. All food is supplied from other places, and only for commercial and trade needs. The so-called relying on the mountains to eat the mountains, relying on the water to eat the water. There are many trees in the south, and the sale of timber alone is enough for the locals to make a living. Then slowly look for local characteristics in order to achieve sustainable development. ”

Lu Bu nodded, Lu Tianlong had such a mind at this age, which already made Lu Bu quite satisfied.

Lu Bu smiled: "The grassland can continue to develop because it has an infinite number of grasslands. All they need to do is herd their cattle, sheep and horses in exchange for the supplies they need. Although there are many trees in the south, there is one less when one is cut down. If the population grows massively, how many years do you think it will last? ”

"This!" Lu Tianlong was stunned, this kind of problem with calculation, where could he calculate it all at once.

"The people take food as the sky, and the country takes food as the foundation. No matter how much trade is done, some local food still needs to be grown. The grassland is not planted now, but I will continue to tame the grassland people. After all the northern steppe people are tamed, the grasslands still have to grow grain. Even if you don't grow staple foods, you have to grow vegetables. If I say I want to grow food in the mountains, what do you think you can do? ”

Lu Tianlong was stunned again, growing grain in the mountains, how to grow this?

Even if it is dry land to grow grain, it has to be flat.

These mountains are all dense forests, and even if the trees are cut down and cleared, there is no way to plant them!

Lu Tianlong inspected the surrounding mountains and forests while thinking about countermeasures.

Since Lu Bu raised this question, with his understanding of Lu Bu, there must be a way to do this.

After pondering for a long time, Lu Tianlong still couldn't think of a way. Lu Tianlong had to look at Xun Yu and the others on the side, hoping to get some instructions.

However, seeing that Xun Yu and the others were also frowning, they didn't seem to think of a good way.

Suddenly!

"Father, Emperor, Emperor, Cao'er has thought of a way!" saw Lu Cao jumping over.

Lu Bu smiled: "Oh, Cao'er has thought of a good way, tell my father quickly!" ”

"Father, slow down!" saw Lu Cao running to get a pen and paper, and then began to draw in front of everyone.

I saw that Lu Cao first drew the appearance of a mountain, and then drew horizontal bars.

As soon as he saw this picture, Lu Bu couldn't help but raise the corners of his mouth.

Although Lu Bu understood, everyone present didn't understand!

"Sister, what are you painting here?" Lu Tianlong couldn't help asking.

"Stupid!" Lu Caojiao drank: "My name is terraces, do you understand the terraces." Knowing that the stairs are not, the stairs are ladder by ladder. This princess has seen that many mountains and forests in Guizhou are gently sloping terrain. As long as the trees are cut down and dug into terraces, won't you be able to grow food? ”

What the!

Lu Tianlong was momentarily stunned.

Xun Yu on the side flashed brightly, and immediately praised: "Princess Dazhi." If this terrace is born, it will be passed down for generations. In this way, several states in the south can be vigorously developed! ”

Xun Yu had seen the rooster map drawn by Lu Bu and knew that Lu Bu in the southern region was to be vigorously developed.

Even if it is wasteland and primeval forests, Lu Bu has to develop them.

was praised by Xun Yu, Lu Cao was even happier, and hurriedly rushed to Lu Bu: "Father, Emperor, Emperor, is this method good?" ”

"Hahahaha!" How Lu Bu didn't like it: "Okay, it's very good." You all remember that the system of terraces was created by my children. When I go back, I have to remember it in the history books! ”

"We'll keep it in mind!" Everyone responded in unison.

At this moment, Lu Cao was even happier. Remembering the history book, this is the name of the history.

For Lu Cao at this age, it is already the highest vanity.

It's just that Lu Cao was favored, and Lu Tianlong was a little depressed.

Obviously, he was tested for him, but he didn't expect this method, but he was thought of by Lu Cao.

It can be said that with this terraced system, not only the southern zone can grow a variety of grains, but also the northern states are the same.

Now the population is small, and there are a variety of South American species, so there is no shortage of food. Therefore, Lu Bu did not organize much land reclamation here.

After all, the population is limited, and the original land cannot be planted, so how can it be possible to open up wasteland.

But with the population explosion, there is not enough land to cultivate.

So, planning ahead is something that a king must consider.

Now China is full of children, and when they grow up and have another generation, there will definitely be more than hundreds of millions of people.

If Lu Bu doesn't control it, it won't take many years to reproduce the population of the next generation.

Therefore, in this era when the total population is very small, Lu Bu wants to suppress the alien race as much as possible and keep the Han population to the maximum.

Well, it is best to control the total global population within 5 billion, and the Han people must be more than half to be able to develop to 3 billion.

If China is not enough, then go and occupy the world.

Occupy all the best territory, and let the aliens go to remote areas to live a hard life.

The goal is 3 billion Han Chinese, but now the Han people are at most 30 million. You know, there are 10 million more children.

If it weren't for Lu Bu who changed history here, the Han population would have dropped to what extent.

Well, a hundredfold increase, in fact, it won't take many years.

As long as Lu Bu lived long enough, he believed that he would be able to see that day.

Lü Bu stayed in Guizhou because he decided to lead his ministers and the people of Guizhou to dig out the first terraced fields.

He's going to make that history.

He wanted to let these scholars, who had never worked in the fields, go down to the fields and touch the mud, so that they could know the hard work of the working people.

More importantly, Lu Bu wanted to take the opportunity to temper Lu Tianlong's will.

has never planted the land, how can Lu Tianlong understand the bitterness of the people at the bottom.

Only by understanding it, in the future, Lu Tianlong can put himself in the shoes of the people and better govern the country.

It is easy to fight the country and it is difficult to defend the country, this is the truth.

Similarly, only Lu Bu knew how beautiful the terraced rice fields were in later generations.

In those days when there were no machinery, every large terrace was dug out bit by bit over a period of decades or even centuries.

Those are the crystallization of the hard work of the ancient working people.

Lü Bu was preparing to dig and build terraces, and Pang Tong, who was in Jingzhou, was also considering follow-up military plans.

The state of Wu has already withdrawn its troops, and the rear of the country of Hua is completely worry-free.

The main purpose of this campaign is to conquer the state of Wu, and it is really difficult to have the Shu army pulling here.

Therefore, what Pang Tong thought about was how to make Shu withdraw its troops.

Eventually, Pang Tong came up with a solution.

That is the threat, the threat of absolute force.

Pang Tong is to let the airship load the bomb to Shu County.

What are you doing, of course, it was a bomb in the air to blow up the glass of Liu Bei's house.

Liu Bei's palace dropped a few bombs, and the ministers' mansions also dropped a few bombs. Then, it must be a littering of paper books, and Liu Bei ordered the withdrawal of the army.

The time is only given for five days, and after five days, the soldiers and horses of Yongan will not retreat, so they will blow it up every day.

With a steamship, Liu Bei spent five days to deliver the military order to Yong'an.

At this moment, the entire upper echelons of Shu were trembling with fear.

Compare it, Pang Tong is too shameless, too shameless!

But what if you scold it, Shu doesn't have anti-aircraft guns, and there is no way to take the Chinese airship at all.

Although Liu Bei got the airship technology given by Wu Guo here, it has only just been developed!

The frightened officials suggested that Liu Bei ordered the withdrawal of the army, and Wu Guo would die, and they could no longer control it.

Now it's time to protect yourself first!
