Lu Tianlong pondered for a moment: "When I returned to my father, my son thought that we should follow the strategy of the grassland. All the food is supplied by other places, and only the needs of trade supply and demand. The so-called relying on the mountains to eat the mountains and water to eat water. There are many trees in the south, and selling wood is enough for the locals to survive. Then slowly find local characteristics in order to achieve sustainable development."

Lu Bu nodded. Lu Bu was quite satisfied with this kind of mind at this age.

Lu Bu smiled and said, "The grassland can continue to develop because it has endless grasslands. They only need to raise cattle, sheep and horses to exchange for the necessary supplies. Although there are many trees in the south, one tree will be cut off. If the population grows a lot, how many years do you think it can last?"

"This!" Lu Tianlong was stunned. He could not figure out such a problem with calculations at once.

"Food is the most important thing for the people, and the country is the basis for grain. No matter how much commerce is done, local food still needs to be planted. If the grasslands are not planted now, I want to continue to tame the grassland people. After all the northern grassland people are tamed, the grasslands still need to grow grain. Even if the staple food is not planted, vegetables must be planted. If I say I want to grow grain in the mountains, what do you think can be done?"

Lu Tianlong was stunned again. How to grow grain in the mountains?

Even if you grow grain on dry land, you have to make it easy to grow on the ground.

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

While inspecting the surrounding mountains and forests, Lu Tianlong thought about countermeasures.

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

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

However, Xun Yu and others also frowned, and they seemed to have never thought of a good idea.

Sudden!

"Father, Zhao'er thought of a solution!" But Lu Zhao jumped over.

Lu Bu smiled and said, "Oh, Zhao'er has thought of something good, tell his father!"

"Father, wait!" But Lu Zhao ran to get paper and pen, and then began to draw pictures in front of everyone.

I saw Lu Zhao first drew a mountain, and then drew horizontal bars.

When Lu Bu looked at the picture, he couldn't help but raise the corner of his mouth.

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

"Sister, what are you painting?" Lu Tianlong couldn't help but ask.

"Stupid!" Lu Zhao shouted: "I'm called terraces. Do you understand terraces? Do you know whether stairs are stairs. I have seen them. Many forests in Guizhou are gentle terrain. As long as the trees are cut down and then dig them into terraces, will you be able to grow grain!"

What!

Lu Tianlong was stunned for a moment.

Xun Yu, who was beside him, flashed with a flash of light and praised him instantly: "The princess is wise. If this terrace is born, it will be passed down for generations. In this way, several states in the south can develop vigorously!"

Xun Yu had read the rooster map drawn by Lu Bu and knew that Lu Bu in the southern area should develop vigorously.

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

When Xun Yu praised him, Lu Zhao became even happier and rushed to Lu Bu: "Father, is Zhao'er's method good?"

"Hahahaha!" Lu Bu didn't like it: "Okay, very good. You all remember that the terraced fields were created by my Zhaoer. After you go back, you must remember them in the history books!"

"Let's remember!" Everyone answered.

Now, Lu Zhao was even happier. He recorded history books, which was called "left in history".

For Lu Zhao at this age, he is already the highest vanity.

However, when Lu Zhao was favored, Lu Tianlong became a little depressed.

It was obvious that he was tested, but he didn't expect this method, but Lu Zhao thought of it.

It can be said that with this terraced field system, not only can there be a variety of grains in the southern areas, but the northern states are the same.

Now there is a small population, and there are also various South American species that have made it difficult to shortage. Therefore, Lu Bu did not organize many land reclamation here.

After all, the population is limited and the original land cannot be planted, so how can we open up land?

But with the explosion of population, these lands are not enough to plant.

Therefore, preparing for the future is something that a king must consider.

Nowadays, there are children everywhere in China. When they grow up slowly and have another generation, they will definitely have more than hundreds of millions of people.

If Lu Bu did not control it, it would not take many years to reproduce the population of later generations.

Therefore, in this era when the total population is small, Lu Bu should try his best to suppress foreign races and keep the Han people at the largest population.

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

If China is not well-funded, then it will dominate the whole world.

Take over the best territory and let the aliens live a hard life in remote areas.

3 billion Han people are the target, but now Han people are at most 30 million. You should know that there are still 10 million children.

If it weren't for Lu Bu's history that changed, the Han population would have dropped to a level.

Well, it won’t take many years to increase it by another hundred times.

As long as Lu Bu lives long enough, he believes he will see that day.

Lu Bu lived in Guizhou because he decided to lead his ministers and the people of Guizhou to dig out the first terrace.

He wants to set this historical record.

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

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

Without planting the land, how could Lu Tianlong understand the bitterness of the lower class people?

Only by understanding can Lu Tianlong put himself in his shoes in the future and better govern the country.

It is easy to conquer the country and difficult to defend the country. This is the ultimate truth.

Similarly, only Lu Bu knew how beautiful the terraces in later generations were.

In that era without machinery, every large terrace was dug out bit by bit after decades or even hundreds of years.

Those are the crystallization of wisdom that the working people in ancient times have worked hard.

Lu Bu was preparing to dig and build terraces, and Pang Tong, who was in Jingzhou, was also considering subsequent military plans.

The Wu Kingdom had already withdrew its troops, and the rear of China was completely worry-free.

This battle was mainly to conquer the Wu Kingdom. It was really difficult to deal with the Shu army here.

Therefore, what Pang Tong thought about was how to withdraw his troops from Shu.

Finally, Pang Tong came up with a method.

That is threat, threatened with absolute force.

Pang Tong asked the airship to go to Shu County with bombs.

What are you doing? Of course, you are dropping bombs in the air to blow up the glass of Liu Bei’s house.

Liu Bei threw a few bombs in the palace, and a few bombs were also thrown into the residences of the ministers. Then, he must have thrown away paper books and asked Liu Bei to order the withdrawal of his troops.

Time is only given to five days. After five days, Yong'an troops will not retreat, so let's blow it up every day.

With the steamboat, Liu Bei spent five days enough for the general to deliver the order to Yong'an.

Now, the entire upper class of Shu Kingdom was trembling with fear.

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

But what if I scolded me? Shu Kingdom does not have anti-aircraft guns, and there is no way to deal with the Chinese airship.

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

The frightened officials all suggested that Liu Bei order the withdrawal of troops, and the Wu Kingdom would be destroyed, and they could no longer control it.
Chapter completed!
