Cheap platform.

"Duke Wei, I was negligent for a moment and forgot that this Changshan is already a feudal country of Duke Wei."

Yang Feng said to Cao Cao with a smile.

As he spoke, he also wiped the soil on his hands, and at this moment, on the newly reclaimed wasteland behind him, Chang Shan Taishou was trembling and trembling with a group of officials to farm for His Majesty the Emperor, and a canal was obviously opened by the Emperor himself to divert water from the Hutuo River, and a small coal-fired steam turbine drove the generator and then drove the pump to a water tower, and then through the water pressure into the pipeline of this farmland, and then turned into a spray irrigation of the newly planted crops around it.

This is Yangfeng's agricultural experimental base.

In addition to the tropical fruits grown in Taiwan and the rubber trees in Rinan, all other crops are here, cotton area, grain area, vegetable area, fruit area, and even pasture area and tree area, each area uses this modern irrigation system.

All machinery is handmade by Yang Feng.

Even he also built a palace here to prepare for permanent residence, to put it bluntly, it is to take reinforced concrete to build a few small buildings, this is not a big project, concrete he burns himself, next to Taihang Mountain there is no shortage of stones, guarding the Jingcheng coal mining area does not have to worry about fuel, and there are iron mines in the south can provide steel, all kinds of facilities can be built up with nearby materials, in fact, there are a few things in the vegetable and fruit area that also need to buckle the greenhouse, although the plastic greenhouse is too complicated but the glass greenhouse is very easy. In short, although the seeds have begun to be sown at present, the real construction has just begun, and there are still a lot of projects in the future, even including industrial construction, roads, it is said that he will transport coal to build roads, but Yang Feng ignored one thing, that is, this place is not his, including Changshan, ten counties have been given to Cao Cao as a fief, which is the scope of Cao Cao's Wei fief.

"Your Majesty laughed."

Cao Cao smiled and said: "This whole world is not the king's land, the minister is only the minister of His Majesty's land, the minister is too big a fief is not suitable for human ministers, and wants to dedicate the nine counties outside Wei to Your Majesty, this Changshan will be dedicated to Your Majesty." ”

"How can this make the land of the Duke of Wei and the Duke of Wei belong to the Duke of Wei, and there is no reason to take it back."

Yang Fengfeng said.

"You just take it quickly, you have planted it, can I still dig it up for you?"

Cao Cao sneered.

"Your Majesty, this is a sincere dedication to Your Majesty!"

He hurriedly said.

"In that case, I'm not welcome, but I can't ask you for nothing, I passed through the Western Regions on this trip, and got a gold mine in Dunhuang, so how about giving Wei Gong Yi Changshan? If the Duke of Wei can hire someone to mine this gold mine, I dare not guarantee that 10,000 taels of gold can be guaranteed every year, and this mine will belong to the Duke of Wei, and the gold mined has nothing to do with the imperial court! ”

Yang Feng said.

Cao Cao's ten-county fiefdom had to be settled.

His ten counties are too big, Hedong, Hanoi, Wei, Zhao, Zhongshan, Changshan, Julu, Anping, Pingyuan, Ganling, respectively, correspond to the north bank of the Yellow River from Linfen to Yuncheng, and Yang Feng in the Northern Song Dynasty pockets to hold the Jin army, and then north of the Yellow River except for the east of Beijing, Tianjin and Hebei, all of which are Cao Cao's fiefdoms. It can be said that one-fifth of the core land of the Han Dynasty belongs to him, such a vast territory is completely owned by him, he appoints officials by himself, collects taxes by himself, and has his own army, which is obviously not possible, even if Yang Feng can bear it, Liu Bei and Sun Quan can't bear it, the most ideal is to keep one Wei County but the other nine counties to take it back, but this kind of thing must be handed over by Cao Cao on his own initiative.

It was in this way that Yang Feng told Cao Cao that we could play an exchange of interests, and the latter handed over the land and he gave the wealth as compensation.

As for how Cao Cao chosen......

That Yang Feng doesn't care, anyway, he drew the road out, Cao Cao can go casually, even if Cao Cao doesn't go, it's nothing, anyway, this guy doesn't have a few years to live, he can't do it because of his father-in-law's identity, so Cao Cao also cleaned up the north for himself, which is also meritorious, but Cao Pi has nothing to give preferential treatment, just find a stubble to cut the seal, this is not a big deal in the Han Dynasty, the princes and kings of the clan can cut the seal if they make mistakes, not to mention that he is a duke with a different surname.

Yang Feng: This is giving Cao Cao a chance.

Give their Cao family a chance to die well and even future generations to become rich, if they are unwilling to accept this kindness, then they will be unlucky.

"Thank you, old minister, for your grace!"

Cao Cao took a deep breath and said.

Of course, he also understands Yang Feng's intentions, but this kind of thing still has to be thought about, he is not a person behind him, not even a family, he is also a huge interest group, many people in this interest group are officials of his Wei State, and it is impossible to keep these officials if he hands over his fiefdom, so how to deal with these people? Even if he wants to hand over the fief, he has to wait to see the situation in the future, mainly to see if Yang Feng will unload the mill and kill the donkey in the future, it is still early at this time.

But now Changshan County has handed it over.

Although Yang Feng only occupies a small piece, if he wants to pay it, he has to hand it over to the entire county, which Cao Cao still has this awareness.

In this way, Changshan County returned to the imperial court.

"Your Majesty, is this the immortal seed? Can this thing make the world free of hunger? ”

Cao Cao picked up a piece of sprouted potato and said curiously.

"I can't."

Yang Feng said with a smile.

"Huh?"

Cao Cao looked at him confusedly.

"Can Duke Wei know why my Great Han has always had a particularly difficult time controlling the land outside the Saiwai? Is it that there are not enough soldiers and the general is incompetent? Can those Hulu outside the plug be beaten? ”

Yang Feng said.

"It's not, it's just that the food is not enough, not to mention the outside of the Saiwai land, the old minister when he conquered Wuhuan, but also did his best to dig the canal, so that the grain of the Central Plains can be transported to the north, those Hulu are indeed brave, but after all, there is not much population, if my Han army has grain to drive over the past 200,000 troops, then the Hulu outside the Saiwai is not enough to fight, but the rear is difficult to transport grain, the local cold and cold can not produce much grain, that is, the Xiangping area is barely arable, and then further north, whether Goguryeo or Buyeo is actually half farming, half fishing and hunting, They will starve to death if they simply farm. ”

Cao Cao said.

"The colder this thing is, the more abundant it will be, even if you plant it on the edge of the black water, you can yield two thousand catties per mu."

Yang Feng said with a smile.

Cao Cao looked at him dumbfounded.

"Tuntian Liaodong, immigrants to the real side, step by step, build a fortress forward, in less than 20 years, all the Hulu in the north can be squeezed to death."

Cao Cao then said with a solemn face.

"It also likes drier land, and it is better to be looser, such as those grasslands in Shuofang, as well as the loess ridges in Shangjun and those places in the north are also very suitable for it, and it likes high places, such as those lofty mountains in the southwest, especially those high mountains in Yuejun, which is simply a happy land for this thing, basically all places can yield at least 2,000 catties per mu."

Yang Feng said.

"You can lure the Qiang Xiongnu and other generations to make them a citizen and get out of the control of their tribal leaders."

Cao Cao said.

"Wrong."

Yang Feng said.

"Your Majesty, please advise."

Cao Cao humbly asked for advice.

"This is only planted in the Northeast, and then given to the Huns and other generations."

Yang Feng grabbed a handful of corn and said.

"What's in it for you?"

Cao Cao asked suspiciously.

"This thing is a good thing, although the potatoes are good, it is difficult to call them staple food, in fact, between the grain and vegetables, it is obviously not enough to eat potatoes, but this thing is the real staple food, there is no difference with the rice and wheat and the like, and the yield per mu can also reach two thousand catties if it is done well, but this is not its biggest benefit, its biggest benefit is that it cannot be retained, and it needs to be treated separately, and at present, this Han Dynasty is a person who knows how to treat seeds, and the prime minister can understand what I mean?"

Yang Feng said.

"The old minister understands."

Cao Cao nodded without hesitation.

He understood too well, first set up a demonstration area to plant this, and then find those Qiang Xiongnu leaders to visit and let them know the benefits of this, and then let them reward them with immortal seeds to plant on the condition of county, so they went back to plant, and the next year they were sure that they would plant with their own seeds, but the result was starvation. If you don't want to starve to death, you have to come and ask for help, at that time, they have to do whatever they want them to do, and if they want them to scatter and replenish them in various places, then they have to accept it, anyway, they don't have the ability to come out to grab food, and they can't skip eating.

In this year, the grain output was miserable, and no one could hold back the staple grain with a yield of 2,000 catties per mu.

At this time, a pound is 250 grams.

And in the same way, even if they don't plant all of this, but only part of the corn, the first year of the harvest will definitely be expanded and the next year will be replaced by this, so that even if the yield will not be extinct, as long as the yield shrinks by half, then there will be only a mass famine waiting for them. At this time, most of the attached Qiang Xiongnu have been agrarian, nomadism is no longer their main source of food, the five Xiongnu are almost all in modern Shanxi, and the left even goes to Linfen, they can not still be nomadic in this area, once they encounter this level of famine, there is really a danger of extinction.

At that time, the imperial court could do what it wanted with the grain.

These people will be destroyed if they resist, they don't have the guts, at this time the Han army is a real warrior in a hundred battles, and it is not the same as playing with a fierce general such as Zhang Liao to clean up a few internal Huns, and this overwhelming military advantage has already been proved when the last expedition to Wuhuan was made.

In other words, didn't Cao Cao know the harm of Wuhu's internal migration?

Of course he knows, it's just that he needs the population too much, but it's not a good thing for these people to live together in clans after all, if these guys who have been agriculturalized can be completely dismantled, for example, a county across the country is divided into several households, under the banner of letting them go to eat, then it won't take a few years for them to completely integrate, and it is impossible for them to make trouble anymore to this extent, and the names of these Hulu will completely disappear.

"Look, sometimes you don't have to use a knife to kill people and exterminate people!"

Yang Feng said with a smile.

"Your Majesty, a celestial being, is beyond the reach of ordinary ministers."

Cao Cao said with a smiling face.

At this moment, this pair of Weng sons-in-law suddenly felt confidant.
