"This thing is quite similar to Pueraria root."

Cao Cao said with a sweet potato.

"Duke Wei, if I say this thing can make my Han population more than 400 million, will Duke Wei believe it?"

Yang Feng said with a smile.

"Your Majesty, before the chaos, there are only 40 million people. Even if you add slaves and hidden households, there are only 50 million people in the country! Can this thing increase the population ten times?"

Cao Cao said in horror.

"This is what I said, which can make no hunger in the world, but it's just a matter of starvation. This thing is not something that nourishes people. Eating this every day can only ensure that you won't starve to death. But the benefits of this thing are also very simple. First, the yield is high, so high that you can't even imagine. The land is suitable for proper management and sufficient water and fertilizer, and it is easy to exceed ten thousand pounds. If you don't pick up the land, you will still collect a lot of trees when you go to the wild mountains and rivers there at this time. In addition, you can leave a few trees in the ground without any seeds.

By raising seedlings, you can grow a bunch of seedlings, and then you can live in the soil. If you don’t leave seeds, you can cut branches on other vines that have grown. This species is mainly planted in mountainous areas. Whether in the Taihang Mountains, the Taishan area, the Qinling Mountains, or even the mountains and steep mountains in the Minyue area, you can all grow well. It can be said that with this species, the entire mountainous area, which was originally uninhabited in my Han Dynasty, can live in people, and supplemented by corn, potatoes, etc., it can be said that all mountainous areas can become places with prosperous populations.

So does Mr. Wei think that 400 million is amazing?

But the same thing is true. This thing is definitely not good for raising people. If you feed these 400 million people as slaves, then plant this. If you want to raise a group of real athletes, try to promote those real food.

But this can be used in the future.

After this product is promoted, it is best for Mr. Wei to issue an order to prohibit the use of grain to make wine. In addition, millet can also be used to make wine. After these two products are promoted, only these two products and fruits are allowed to make wine, but it is strictly forbidden to use other grains to make wine."

Yang Feng said.

Sweet potatoes are unsuccessful in the prosperous era.

It is good to drink sweet potato and sorghum. The latter already exists at this time, but it is very rare to plant, and it is within its cultivation and promotion scope, which can just meet the needs of alcoholics. As for the poor taste...

It's nothing to do with him.

Besides, it is better than the so-called fine wines at this time.

But even so, Cao Cao was still shocked and did not wake up for a short time. What is the concept of 10,000 kilograms per mu in this era? Even the best water irrigation field in this era, the best year limit is only ten hu, equivalent to more than 900 kilograms of millet, without peeling. Moreover, this is also the limit of the current grain yield per mu. However, there are very few such fertile fields, and the acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acres of acre

And this is ten times that of the Mu Zhong Field.

Cao Cao was really a little dizzy, not to mention that Yang Feng also said that this was specially planted in mountainous areas. No one cultivated the land now, and the grains planted may not be able to recover the seeds. If this is true, as long as there are people, the cultivated land of the Han Dynasty could almost expand ten times, and there was no land that could not be cultivated in the world.

You must know that there was no one in the mountainous area at this time.

To give the most intuitive example, Changsha County and the adjacent Wuling County, the former is the plain, the latter has a small number of plains and most mountainous areas. The former is 1.5 million thirteen counties before the chaos in the world, and the latter has 250,000 thirteen counties. The pure mountainous areas include 16 cities and 110,000 Yizhou County with Dianchi Lake as the core, covering 700,000 Kuaiji County in Zhejiang and Fujian, and the vast majority are in the Jiangsu, Shanghai and Hangzhou areas. The pure plains represent the 17 cities and 1.4 million thirty-one areas of Yingchuan County, which is less than one-twentieth of Kuaiji County. This is the gap between mountainous areas and plains in this era.

If all the mountainous areas can be turned into fertile land, then the 40 million people are really not a fantasy!

"But the premise is that you don't fight again!"

Yang Feng said from the side.

"War will bring casualties, war will cause food production to drop sharply, war will also bring about large-scale plagues. Continuous war will double the population's weakness. Wars that last for decades will be ruined. When the population is weakened to the point where it cannot defend its homeland, alien races will invade. The most effective way for them to take root in this land is to kill the original residents to less than theirs, so they will continue to kill. All those destructive countries are basically like this.

There were several countries that were as powerful as the land of China a thousand years ago, but until now we are only one of us, and all the others were destroyed in this way.

Ancient Egypt was destroyed.

Their remnants are now slaves at the feet of the Roman conquerors.

Ancient India was destroyed.

The Aryans who conquered them occupied their land and divided the people into four levels. Originally, the inhabitants of that land were the lowest untouchables, and then destroyed everything about them and made up a new myth for them. Even now, they believed that they were born untouchables based on this myth.

Isn't it scary?

Being conquered by others, deceived by others, and then thousands of years later, they already think that they are born untouchables, and they are born to be slaves to the descendants of those conquerors, and they are born to be unable to resist them. Isn’t this a bit creepy? If your war continues, I guess no one of you can do anything to each other, this war may have to be fought for decades, until your third generation. Then as the population of China continues to decrease, the people of the four barbarians will inevitably penetrate into the Central Plains. At this time, the Huns have lived in Hedong, and the Wuhuan also lived in Youzhou. So in a few decades, should they live in Chang'an and Luoyang? Who can they control them when they suddenly rise up?

Then will they occupy the magpie nest?

Will they destroy our books and burn our history, and then make up a myth to tell our descendants that they are born untouchables and are born their slaves?”

Yang Feng continued.

"Old, the old minister has made a mistake!"

Cao Cao said in a cold sweat.

He divided the five Xiongnu tribes, and he did it for the Xiongnu people to live all the way to Hedong. Although the Wuhuan people could not say that they were fully responsible, they did pack all these guys back and live in Hebei after conquering Wuhuan. It turned out that Wuhuan only went to Jidong. It was obvious that His Majesty the Emperor was a little dissatisfied with this.

"The past has passed. Since they have entered the border, it will eventually be solved. Fortunately, we will also be from the Aryan Association. Just ask Zhang Lu to strengthen his mission to them. He did a good job in dealing with the Di people. Don't have prejudice against them because of the Yellow Turbans. The problem of the Yellow Turban Army is not a religion. If the people are well-fed and well-dressed, what can they do if the Zhang brothers can be deceived? What's more, I have already given the heavenly book and the person who is doing it is right.

The people must have a basis for their careers. Similarly, the best way to educate barbarians must make them forget their first, and the best way to make them forget their first is to give them a religion. I will take time to help Zhang Lu. After they all convert to the right path, they will then dismantle their tribes and disperse their tribes. The Huns and Wuhuans all went south, while the Di and Qiangs all scattered them in Qi and Lu, Hebei, and other places. Ten Han families and one family and four barbarians were farmed together and married each other. Who will remember what they were in fifty years?”

Yang Feng said.

"Your Majesty's wisdom is beyond the reach of the old minister."

Cao Cao said sincerely.

Obviously, he is still not as experienced as the Divine Emperor in this kind of thing. Although he also knew that he wanted to educate these four barbarians, and he did have some achievements. For example, he later taught the Huns to become famous people, but these were limited to the upper class, lacking the education of the entire tribe, and even more lacking the systematic teaching methods of Yang Feng. They were completely targeted means of education, and there was no spiritual control means, so in the end they were useless.

Of course, the main reason is that he cannot fly around in the air every day.

But don’t underestimate Yang Feng’s flight show, this thing is more effective than any education.

The reason why Yang Feng chose to enter the southwest before was to scare the mountain people there in this way, and the chiefs like Meng Huo were so scared that they were sweating coldly on his face.

"Your Majesty, how should the fight be stopped?"

Cao Cao continued.

He actually came to tell Yang Feng that he, Liu Bei and others had already set a date for the fight, just after the autumn harvest this year.

The venue in Luoyang.

The three of them participated, including Zhang Lu, Gongsun Kang, Shi Xie, Yang Biao and Sima Fang, representing the court. In this way, there are seven companies in total. The latter is the host. The first six families each carry 3,000 troops and horses, and at most half of the limited infantry and cavalry, and all parties are responsible for their own military supplies. Of course, this is easy. Even Liu Bei's transportation can go north from Jingzhou to Nanyang, and then transport it by land to Luoyang, or he and Sun Quan share a transportation line, that is, go north from Ruxukou, and Shi Xie from Lingnan to north, and he can also go this line. His army can also go directly to Luoyang along the Lingqu water transportation.

However, Gongsun Kang did not have water transportation.

But what this guy lacks the most is horses, and his sailing level should be not low. The Gongsun family's control over Denglai and other places until ten years ago. If they wanted to control such enclaves across the sea, their sailing level in Liaodong would not be worse. In other words, they could also use ships to transport materials across Liaodong Bay to Haihekou, and then transfer to Cao Cao's northern water transportation network to Luoyang. The only troublesome thing is Zhang Lu, but he can also go down the Han River to Xiangyang and turn to Tanghe to Sheqidian, and then transfer to land transportation. Of course, in fact, there is no need to be so troublesome. Just bring gold and silver to buy. Sima Fang and other aristocratic families all have food and do not mind selling it to these potential allies.

"Your Majesty Wei can handle this matter, and you will be the master of the government affairs!"

Yang Feng said with a high attitude of delegating power.

"Your Majesty, this old bone cannot bear such a heavy burden!"

Cao Cao said with a smile.

"Then let your son help me. Duke Wei is my uncle, so why should you and me share with each other!"

Yang Feng also said indifferently.
Chapter completed!
