"It's kind of like kudzu."

Cao Cao said with a sweet potato.

"Duke Wei, if I say that this thing can make the population of my Han Dynasty exceed 40,000, does Duke Wei believe it?"

Yang Feng said with a smile.

"Your Majesty, before the chaos, there were only 40 million, and even if you add slaves and hidden households, the people of the whole country are only 50 million! This thing can increase the population tenfold? ”

Cao Cao said in horror.

"This is what I said, there can be no hunger in the world, but it is just starving and not dying, this thing is not a thing to raise people, eating this every day can only ensure that you do not starve to death, but the benefits of this thing are also very simple, one is the high yield, so high that you can't imagine it, the land is suitable for proper management, the water and fertilizer are sufficient, and it is easy to pass 10,000 catties, and you don't pick the land, you are at this time to go to those barren mountains and mountains over there to carry a few trees, it will also collect a lot. In addition, you don't need seeds, just leave a few seedlings in the ground to raise a bunch, and then insert them into the soil to live, and if you don't have seeds, you can cut a branch on another vine that has grown and plug it to grow. This thing is mainly planted in the mountainous areas, whether it is in the Taihang Mountains, Mount Tai, or the mountains of the Qinling Mountains and even the mountains of Minyue, all of them can grow very well, it can be said that there is this thing in the whole Han Dynasty originally no one in the mountains can live in people, supplemented by corn and potatoes and the like, it can be said that all the mountainous areas can become a prosperous place.

So does Wei Gong think 40,000,000 is amazing?

But again, this thing is definitely not good for raising people, if you feed these 40,000 people as slaves and livestock, then plant this widely, if you want to raise a group of real athletes, then try to promote those real food.

However, this can be used for sake brewing in the future.

It is said that after the promotion of this thing, it is best for Wei Gong to issue an order to prohibit the use of grain to make wine, and Shu millet can also be used to make wine, after the promotion of these two things, only these two things 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 in full bloom.

It's good to drink sweet potato roast and sorghum burn, the latter already has it at this time, but it is very little planted, and it is also in the scope of his cultivation and promotion, which can just meet the needs of drunkards, as for the bad taste......

It's all about him.

Besides, it's better than the so-called fine wine at this time.

But even so, Cao Cao was still so shocked that he didn't wake up for a short time, what is the concept of 10,000 catties per mu in this era? In this era, even if the best watered fields and the best years are the limit, the limit is only ten hundred, which is equivalent to more than 900 catties of millet, and it has not shed its skin, and this is also the limit of the current grain yield per mu. But there are very few such fertile fields, the acres of land are the foundation of the country, and the unification of the world of the Qin State is supported by the support of those acres of fields in Guanzhong, and he can also unify the north by relying on the same acres of fields in the Yingchuan area, but the vast majority of land yields per mu are only one-third of this output.

And this is ten times the size of the acre of Zhongzhitian.

It is said that Cao Cao is really a little dizzy, not to mention that Yang Feng also said that this is specially planted in the mountainous thin land, those lands are now uncultivated at all, and the grain planted may not be able to recover the seeds, if this is really the case, as long as there are people, the cultivated land of the Han Dynasty can almost expand ten times, and there is no uncultivable land in the world.

You know, there is no one in the mountains at this time.

To give one of the most intuitive examples, Changsha County and the adjacent Wuling County, the former is plain, the latter is a small number of plains and most of the mountainous areas, the former has 1.5 million people in 13 counties before the world chaos, and 250,000 people in 12 counties in the latter 12 counties, and 110,000 people in 16 cities of Yizhou County with Dianchi Lake as the core in the pure mountainous area, including 700,000 people in Huiji County in Zhejiang and Fujian, most of which are in the area of Jiangsu, Shanghai and Hangzhou, and 1.4 million people in 17 cities of Yingchuan County on behalf of the pure plain, with an area of less than one-twentieth of Huiji County. This is the gap between the mountains and the plains in this era.

If you can turn the mountainous areas into fertile fields, then 40,000,000 people are really not a fantasy!

"But only if you don't fight again!"

Yang Feng said on the side.

"War will bring casualties, war will cause food production to drop sharply, war will also bring large-scale plagues, continuous war will weaken the population will be doubled, wars that last for decades will really have a hundred people, and when the population is weakened to the point that they can't defend their homeland, the alien race will invade, and if they want to take root in this land, the most effective means is to kill the original inhabitants less than their number, so they will continue to kill, and all those countries that have perished are basically like this.

There were still several countries that were as powerful as the land of China a thousand years ago, but now we are the only ones left, and all the others have been destroyed in this way.

Ancient Egypt was destroyed.

Their remnants now serve as slaves at the feet of the conquerors of Rome.

Ancient India was destroyed.

The Aryans who conquered them took possession of their land and divided them into four classes, and the inhabitants of that land were the lowest untouchables, and then they destroyed everything and made up a new myth for them, and even now they believe in the myth that the Aryans have made up for them, according to which they consider themselves to be natural pariahs.

Isn't it scary?

Isn't it a little creepy to be conquered by someone else, to be deceived by someone else, and then thousands of years later, they already think that they are born pariahs, that they are born to be slaves to the descendants of those conquerors, that they are born not to rebel against them? If your war continues, I estimate that none of you can help anyone, this war may have to be fought for decades, until your third generation, then as the population of the land of China continues to decrease, the people of the four Yi will inevitably infiltrate the Central Plains, at this time the Huns have lived in Hedong, Wuhuan also lives in Youzhou, so in a few decades they should live in Chang'an, Luoyang? At that time, who can control them if they rise up again?

And then will they be occupied?

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

Yang Feng continued.

"Old, the old minister made a mistake!"

Cao Cao said in a cold sweat.

The five Xiongnu are his share, so that the Huns have been living in Hedong is also what he did, although the Wuhuan people can not say that he is completely responsible, but he did pack these guys back to live in Hebei after he conquered Wuhuan, it turned out that Wuhuan only went to the east of Hebei, it is obvious that His Majesty the Emperor is a little dissatisfied with this.

"The previous ones are gone, since they have entered the fortress, it will be solved after all, fortunately, we of the Aryan Association will also, let Zhang Lu strengthen his missionary work to them, he has done a good job in dealing with the Di people, you don't have prejudices against them because of the Yellow Turbans, the problem of the Yellow Turban Army is not religion, if the people are well fed and clothed, even if the Zhang brothers can bewitch again, what can they do? What's more, I have given him the Book of Heaven, and those who do it are the right way, and the people must have something to rely on before they can settle down, and the best way to make them forget their ancestors is to give them a religion. I will take the time to help Zhang Lu, when they are all converted to the right path, and then dismantle their tribes and disperse their tribes, the Huns and Wuhuan generations are all south, and the Qiang generations are scattered in Hebei Qilu and other places, ten Han families are mixed with one household and four Yi, farming together and marrying each other, who remembers what they used to be fifty years later? ”

Yang Feng said.

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

Cao Cao said sincerely.

Obviously, in this kind of thing, he is still not as experienced as the God Emperor, although he also knows that he has to educate these four Yi, and he does have some achievements, such as later teaching the Huns to become famous scholars, but these are limited to the upper level, lack of education for the entire tribe, and lack of Yang Feng's systematic, completely targeted means of education, let alone spiritual control, so in the end it is still useless.

Of course, the main thing is that he can't fly around in mid-air every day.

Don't underestimate Yang Feng's air show, this thing is more effective than any education.

The reason why Yang Feng chose to enter from the southwest before was to scare the mountain people there in this way, and to scare those chiefs like Meng Shu, who were lying on his face in a cold sweat.

"Your Majesty, how should the meeting of the soldiers be conducted?"

Cao Cao then said.

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

Venue: Luoyang.

There were three of them who participated, plus Zhang Lu and Gongsun Kang and Shi Xie, Yang Biao and Sima Fang on behalf of the imperial court, so that a total of seven, the latter was the host, the first six families each brought 3,000 soldiers and horses, and the maximum number of foot riders was half, including their respective military supplies were also responsible for each party. Of course, this is very easy, even if Liu Bei's transportation can also go north from Jingzhou to Nanyang, and then transport it to Luoyang by land, or he and Sun Quan share a transportation line, that is, go north through the mouth of the Xukou, including Shixie who goes north from Lingnan, can also take this line, and his army can also go directly to Luoyang along the Lingqu water transportation.

However, Gongsun Kang did not have water transportation.

But the last thing this guy lacks is horses, and his navigation level should not be low, the Gongsun family's control of Denglai and other places has been until ten years ago, if they want to control such an enclave across the sea, their navigation level in Liaodong cannot be bad, that is to say, they can also use ships to transport materials across Liaodong Bay to the mouth of the Haihe River, and then transfer to Cao Cao's northern water transportation network to Luoyang. The only trouble is Zhang Lu, but he can also go down the Han River to Xiangyang and turn to the Tang River all the way to the credit flag shop, and then turn to land transportation, of course, in fact, there is no need to be so troublesome, just bring gold and silver to buy, Sima Fang These families have food, and they definitely don't mind selling it to these potential allies.

"Duke Wei can handle this matter, and Duke Wei is in charge of the affairs of the court!"

Yang Feng said with a high posture of complete decentralization.

"Your Majesty, this old bone can't hold such a heavy burden!"

Cao Cao said with a smile.

"Then let your son help, Wei Gong is my uncle, how can you and I divide each other!"

Yang Feng also said indifferently.
