Bullying the weak and fearing the strong is actually nothing. Anyway, the big man is the strong one, and the Xiongnu is hiding from the big man. Naturally, the big Han will not have any objections to this.

Of course, there are still people who are unhappy, such as Lu Bu, Zhang Fei and other bellicose generals. They are strongly dissatisfied with this behavior of the Huns, but it is useless to be dissatisfied. The Huns still try to avoid it.

When fighting with them, they would raise their weapons and fight until they had no choice but to escape - because they knew that the Han people would not let them go, otherwise they would even throw away their weapons.

In this way, the war against the Huns was only called a war at the beginning. After the first battle, it completely took another strange direction.

"If we fight like this, the Huns will be completely 'cleaned' in less than three years!"

Liu Xuan looked at the stack of memorials in his hand, which recorded all the details of the "Northern Expedition" in detail. Even if he just glanced at it, a lot of time was wasted.

Huang Yueying bit the dried meat in her mouth and glanced at Liu Xuan: "Isn't this what I hope?" Seeing Liu Xuan chuckle, she added: "Don't you think the speed is too slow? If so, let me

Wouldn't it be great if Yu Lin rode out to 'hunt'?"

The Yulin Cavalry can patrol the entire area in the air, and then directly eliminate the target after discovering it. The efficiency is naturally much faster than slowly searching on the ground.

But there are problems. If you search in the sky, you will definitely miss something. This is why Liu Xuan did not ask the Yulin Cavalry to do such a thing.

In addition to these... I just need to find something to do for the Forbidden Army guys who have been holding back for so many years, and finally fight a battle. If they are all idle there, nothing will happen again.ishu.

It's not that the military discipline of the Han army is bad, but in fact, the soldiers and horses who are accustomed to fighting have a certain arrogance, and this arrogance cannot be let out. In addition, Liu Xuan is not the kind of person who sticks to the rules.

People who give up, so even though these soldiers looked decent and well-dressed when they were in Luoyang, they immediately looked different when they were brought out to fight.

"After defeating the Huns, are you ready to attack the Northern Wei directly?"

"It may take a while!"

Liu Xuan was not prepared to continue the war. It was not that the big man did not have the strength, but that he wanted to buy some time for Sun Ce.

The undead army has now received enough equipment, and Sun Ce is making final preparations - in fact, he is bringing these lifeless dead people to cause all kinds of harm in the northwest region of the Northern Wei Dynasty. Now it is not only the remote northern part of the Northern Wei Dynasty that is spreading

There were rumors of ghosts and monsters. Even the Han army got the news.

Lu Bu didn't know the specific situation, but he still made targeted arrangements: the number of soldiers and horses going out for patrols increased, the frequency of patrols increased, and the number of contacts increased, just to prevent any accidents from happening.

If it were in the past, perhaps the generals of the Han Dynasty would not have taken the rumors of ghosts to heart. But after a hundred years of development and changes, who would dare not to take this matter seriously now? Especially Zhang Fei. In

When I heard the news, my first reaction was that Zuo Ci was not dead?

But Zuo Ci's death was confirmed by His Majesty himself. Since His Majesty said he was dead, it meant he was dead.

Then what he thought about was whether Zuo Ci had any other sect members? Is what happened in the Northern Wei Dynasty related to this?

Liu Xuan did not give any answers to the generals' speculations.

He won't let too many people know about Sun Ce and his undead army. Maybe Lu Bu will know the details in the future, but not now.

Liu Xuan hoped that Sun Ce would lead the undead army to wreak havoc on Europe, but it would take time. At that time, it would also be a suitable opportunity for the Han Dynasty to launch an attack on the Northern Wei Dynasty.

After defeating the Northern Wei Dynasty, we can take advantage of the trend and move westward. ishu. Expand along the route that the undead army has caused harm along the way.

“I can probably be busy for another few decades!”

Huang Yueying picked up another small piece of dried meat and rolled her eyes while biting it: "How many people did the big man have at that time?"

Now the population of Han Dynasty will grow faster and faster.

Especially with the collective improvement of the people's physical fitness, the prime of life will also be considerably extended, which means that the Han Dynasty will harvest a large number of strong labor forces in the next few decades - these are also the basis for the source of troops.

(--The fastest update of the house

) At the same time, a large increase in population will also mean that the Han Dynasty can occupy and rule more areas.

And that's not all. As the Han's 'technology' gradually developed, local occupation gradually no longer relied solely on population.

The demand for population will also slowly decrease. If the two factors are combined, in less than fifty years, the Han Dynasty will have the ability to rule the entire earth.

Liu Xuan knew these things, and the ministers in the court had naturally thought of them. After a rough calculation in his mind, Liu Xuan directly came up with a figure: "In fifty years, the population of the Han Dynasty can reach several billions."

!And most of them are young adults!”

The specific amount depends on what the people think.

As life gets better and better, various entertainment industries gradually develop, so that even ordinary people can have some recreational things to do, which means that people are no longer like before, as soon as their daily work is over,

I don’t know what to do except create human beings.

Fortunately, medical conditions have improved now, and the survival rate of babies is much higher than before. Otherwise, the population may have declined even more.

"You have a heavy task!"

After looking at Huang Yueying, Liu Xuan's plan for Dahan can progress smoothly. Huang Yueying is the key here. She must ensure that Dahan's technology can meet this standard before the subsequent arrangements can proceed smoothly.

The most crucial point is: starship.

You must know that the technology of the Cultivation Empire has a very sufficient foundation, and it took hundreds of years and nearly a thousand years of development to reach its current level.

For example, the spaceship I saw last time was a model that was eliminated by the empire, but even a spaceship of that level cannot be built by today's big men.

Without a spaceship, there is no basis for long-distance travel in the universe - immortals can travel the universe, but that does not mean there are no limits.

What's more, if you want the entire empire to develop into the interstellar era, you have to take into account those soldiers who do not have the strength of immortals and ordinary people who need to travel in the universe.

Because if the people can't freely travel back and forth between the planets under their control, then what's the point of occupying this planet? Is it just a place for those immortal-level generals to rest?

In short, we must have a spaceship - and at the same time, there is a technology on the interstellar spacecraft, which is necessary for long-distance flights. Without this technology, interstellar navigation will be a disaster.

Because the distance between planets in the universe is very far, even at the speed of light it will take dozens, hundreds or even thousands of years to fly. Simply flying will definitely not be able to meet the demand.

Therefore, the spacecraft has a technology of folding space for shuttle, folding space from another angle to achieve the purpose of shortening the navigation distance and time consumed.

This cannot be done with the physical body, not even an immortal. The most basic thing is to wear a special mecha - but that special armor is not so much a battle armor as a human being.

The thick tortoise shell has no other function than allowing the monks to carry out individual long-distance voyages.

At least before Liu Xuan left the Cultivation Empire, there was no breakthrough in this technology. According to Liu Xuan's understanding of those guys, it is estimated that even now, they are unlikely to make any big progress.

Therefore, interstellar navigation still relies on interstellar spacecraft.

Over the years, Huang Yueying and the Weapon Refining Department have been making continuous breakthroughs based on the current existing technology. The prototype of the spacecraft is actually the warship currently used by the Han Navy.

Of course, there is nothing much to say about the appearance. The problem that needs to be solved now is power.

Because the size of the interstellar spacecraft is very large, only in this way can it meet the various needs of interstellar navigation, and a larger size requires stronger power to push it, which is inevitable.

At the same time, we must also consider that the starship's navigation environment is in space, so the sealing, heat resistance, cold resistance, etc. must be taken into consideration. These problems are enough to give Huang Yueying a headache for a long time.

On the contrary, if the problem of getting the spacecraft into the air is not a problem at all in the cultivation civilization, even now, Huang Yueying has a way to make Dahan's warships fly - in fact, Dahan has created some experimental spaceships, but these

The spacecraft can only be used inside the earth and cannot enter the universe.

"I'll do the work, don't worry!"

Huang Yueying held her chin up, as if she believed I was right. It seemed that she had enough confidence in her abilities.

But think about it, this girl seems to have a plug-in, she can do almost everything she wants to do, and she never runs into trouble.

Liu Xuan even sometimes wondered: "Have I come to a world where this woman should be the protagonist?" Of course, this idea is just an occasional thought and has no practical significance.

Because even if this is true, and because of his arrival, huge changes have taken place. The world has developed in a new direction according to her own wishes. Even if Huang Yueying is really the 'protagonist', she cannot change all this.

You can only move forward step by step according to your own arrangements.

In addition, Huang Yueying also needs to provide herself with various services...

Touching his chin, Liu Xuan looked at Diao Chan and Huang Yueying in front of him: "We haven't been together for a long time, right?"

As soon as the words came out, Diao Chan was stunned for a moment, and then her little face turned red and she lowered her head without saying a word. However, Huang Yueying glared at Liu Xuan: "I want to make trouble again!"

However, when she said this, there was no hint of disgust in her tone, but she looked very interested. As a result, her appearance made Diao Chan unable to hold her head up even more.
