Perhaps because they had been holding it in for a long time, when they found an opportunity, the Shu Han people wanted to send troops to deal with Lu Bu.

Most of the ministers supported it, so Liu Bei made a decision to finally go to war.

A large army of 100,000 attacked Hanzhong in the north.

If it goes well, he can also fight directly to Chang'an and directly conquer Liangzhou.

In this way, even if Lu Bu's huge territory was broken by him.

Maybe Cao Cao, who is in the West, will become independent and make trouble again.

Anyway, the more chaotic it is, the better. The more chaotic it is, the more profit Liu Bei can gain.

The two airships of Shu Kingdom flew to the northern grasslands, and the other flew to the Kushan Kingdom.

Oceania is too far away and the Shu Han airship cannot fly, so Liu Bei can only go to find Cao Cao.

Similarly, although we know that China has more awesome fighter jets, as long as we don’t go to big towns, China will not be able to discover it.

Even if the people accidentally saw it, the airship had already gone far away and had no location, the Chinese fighter jets could not take their airships.

Yes, China has not yet developed large-scale radar technology, so it is indeed impossible to detect it, and there is nothing we can do about it.

The main reason is that no one else has an air force, so Lu Bu has not invested much in this area.

However, Lu Bu never underestimated the surveillance of Shu Han.

Therefore, as soon as Liu Bei's army moved, the Ministry of War was the first to receive the news.

After Pang Tong received the news, he naturally rushed to submit information to Lu Bu.

Fortunately, China's communications are becoming more and more powerful now. Even if Liu Bei just started his army, China will know everything.

If it were ten years ago, maybe it would be possible that the north would only learn the news if it came to Hanzhong.

After receiving the news, Lu Bu didn't care.

There were 30,000 elite soldiers in Hanzhong to defend Zhang Wei, and Liu Bei wanted to conquer him with 100,000 soldiers and horses, which was a dream.

With the current military strength of China, Liu Bei is more than one order of magnitude.

Because Hanzhong is a major city, Lu Bu has stored a large number of thermal weapons here.

Now as the national teacher, Zhang Lu has also been promoted to Count, and the military and civilians of Hanzhong have benefited from it, and there is no reason to rebel against him.

Therefore, Lu Bu was not afraid of Liu Bei's northern expedition at all, but was even more afraid that Liu Bei would not come.

If Liu Bei's troops did not come, it would be more difficult for him to enter Shu. Liu Bei came to die by himself, so he was so happy.

But what Lu Bu is doing is guiding everyone to drill.

Before solving the problem of water shortage in the north from the root, what Lu Bu could do was save water and use groundwater.

It has drilling technology, even groundwater that can be used at a depth of hundreds of meters.

And the deep wells in this world can only be dug about ten or twenty meters at most.

It can be said that with the deep well, water use in the north can be alleviated within decades.

The most important thing in water conservation is water use in arable land.

As long as Lu Bu can defeat the entire world, he will not be worried about the future food shortage of China.

Therefore, since it is a difficult area to grow grain, then don’t plant it.

Dry land, just plant all dryland crops.

The reason why the Celestial Empire was always worried about food in the future was that China had few arable land and had a large population.

But now the whole world belongs to Lu Bu, so what are you afraid of?

Many staple foods can be stored for several years or even more than ten years. When he is in the future, he will repair his granary and store more than ten years of food. Why don’t he worry about who dares to rebel?

Fortunately, the population is not large now, and although there is a shortage of water, the difficulty of relief is not as high as expected.

Because Lu Bu only guarantees drinking water for people and livestock and does not care about the land, it will be much easier.

Now China stores a large amount of food, and even if it has been famine for two or three years, it can still survive.

Although I am not panicked with the reserves, I can’t feel heartbroken when I see the dried seedlings.

Grain is the foundation of the country, and Jiqing Xusi is a major grain state. Now 10% of them die, 70% of them are dead. How could Lu Bu not feel heartbroken?

And there has been no sign of rain. I am afraid that the food this year will almost be harvested.

Why did the Yellow Turban Rebellion occur and why the world was in chaos? This is the most direct reason.

While rescuing disasters, Lu Bu was also thinking about future development plans.

First of all, Heilongjiang has to immigrate.

As the largest grain province in China, this area must be developed.

With the Heilongjiang water source as the basis, this place is almost not afraid of drought.

Nowadays, the population is small, and Lu Bu only develops flat land and uses mechanical grain cultivation.

Only in this way can Lu Bu be able to store more food before the population explosion arrives.

Furthermore, the colonies are exchanging species, and various grains are grown and stored.

Controlling the population of foreign races and using these foods to support the Han people was Lu Bu’s central idea.

In order to control the grassland, Lu Bu did not grow grain for the grassland, but all supplied it from the inland.

Lu Bu decided to liberalize this policy and let the northern grasslands start to cultivate potatoes and various types of vegetables.

Potatoes are cold plants and are suitable for planting in grasslands.

If you have historical experience, Lu Bu doesn’t need to verify it.

Even greenhouse technology can be passed on.

In this way, the food supply problem in the grassland can also be alleviated.

In a word, Lu Bu wants to break the problem of excessive agricultural population in China in later generations.

He wanted the colonial population all over the world to farm to raise the Han people.

This is what conquest is called.

To achieve this goal step by step is the source of Lu Bu's happiness.

With the airship, the transportation in Shu Han has also been increased by a dimension.

Half a month later, Liu Bei's envoy arrived in Kushan and met Cao Cao.

The messenger was Zhang Song, after all, he was facing Cao Cao. If he was a little shrimp, it would be unequal.

Fortunately, with the world map drawn by Lu Bu, Zhang Song might not have found the location of Kushan.

Zhang Song still knew Cao Cao very well, so he still had considerable confidence in this trip.

Zhang Song said confidently: "Duke Cao, now you have a million people under your command, and you have the territory of the Western Regions such as Kushan, and your power is not inferior to Lu Bu at all. In this way, Cao Gong ascended the throne and became emperor by himself, which is the destiny of heaven!"

"Liu Bei asked you to come to in order to instigate me to rebel?" Cao Cao chuckled and said, "Go back and tell Liu Bei that if you don't want to die, it's better to surrender early. It's his unwise to go against the emperor!"

Zhang Song was stunned: "Duke Cao, the family members of the Cao family have all moved to the Kushan Kingdom, and Duke Cao has no worries anymore. Cao Gong is powerful, so how could Lu Bu not be afraid? The birds are gone and the good bows are hidden. If Duke Cao does not rebel, the Cao family will probably be ruined in the future!"

"Bold!" Cao Cao was immediately angry: "I dare to show off my verbal disputes again, I will kill you. Come and see you off!"

The guards entered and wanted to take Zhang Song away.

Cao Cao was tough, and Zhang Song couldn't help but shouted: "Duke Cao, may you forget the revenge of Prince Pi! If you don't take this revenge, Cao Gong will be a father in vain!"

"You!" Cao Cao was so angry that he exploded: "Dare to humiliate my son, come and dismember this man five horses!"

Zhang Song was immediately dragged down, and Zhang Song, who knew he would die, cursed even more.

"Hahaha, Cao Cao's old thief, you are a hero of a generation, but now you are a lackey. Even if I, Zhang Song, die today, you, Cao Cao, will have to end up in the same situation in the future. You are a hero of a hero, but you are a bear!"
