Three Kingdoms: Being humiliated when joining the alliance, he turned back and recognized his ancest

Dong Cheng's identity is very special, and he is the father-in-law of the Son of Heaven.

If not to hold power yourself, it is to prepare for your grandson.

Now that Dong Guiren is pregnant, if he succeeds in uniting with the princes in various places to revolt, eliminate the Dong clan, and return the government and the Son of Heaven.

He is a great accomplishment, and in this case, he will definitely make his daughter empress.

At that time, the future son of the Han family must come from his Dong Cheng lineage, and he can also enjoy Dong Zhuo's treatment.

This is a big gamble, the bet is won, and it is a great man.

If the bet is lost, none of the Nine Clans can run.

But this is the case in troubled times, if you don't gamble, how can you win?

"Don't care about him, let Xu Rong pay attention to Zhang Lu in Hanzhong, and send someone to Luoyang to inform me of any situation."

Dong Yao didn't care much, now there is a big chaos today, there are frequent attacks between the princes, where is the air control and what is the Son of Heaven.

Just like Sun Ce and Liu Biao, the former in order to avenge his father, the Hengjiang War, have already beaten human brains into dog brains.

The two sides come and go, and I don't know how many bones are buried under the river.

After this battle, the fish were full.

Cao Cao farmed with peace of mind, and although Yuzhou got it, he also complained all day.

Migration, as easy as it is said.

Who will abandon their old home and go to a new place.

In order to let the people of Xuzhou go to Yuzhou, Cao Cao was good at talking and giving many benefits, so he moved some of the population.

Every time he thought of this, Cao Cao would scold Dong Yao from his heart.

But fortunately, there is a lot of land in Yuzhou that can be given to those newly arrived people.

At the same time, Cao Cao also asked his subordinates to turn their brains and improve the tools for cultivating the land.

Change the coupling plough that used to be two oxen and three people to a lighter one-ox plough.

This improvement has greatly improved the farming efficiency of the people and indirectly promoted agricultural development.

This alone, Cao Cao did not mention how happy he was.

The stability of agricultural development is related to the livelihood of the people under his rule.

Dong Yao did rob a lot of his people, Liangzhou, and the prefecture also have countless lands, but can the cultivation efficiency be as fast as him?

Impossible, simply impossible.

Cao Cao improved the cultivation equipment, and Dong Yao was also engaged in it.

However, he encountered a bottleneck and forgot about the Tang Dynasty's plough, that is, the structure of the legendary Quyuan plow.

"Husband, do you think this will work?"

Cai Zhaoji put down the brush in her hand and presented the newly drawn drawing.

"Nope."

Dong Yao shook his head, it was not Cai Zhaoji's technique.

Her own mother-in-law is proficient in Qinqi calligraphy and painting.

Now it is not simple to draw a curved plow, but because of his description, the more he paints, the more he paints.

"What the hell is going on..."

Dong Yao scratched his head, he really couldn't remember the structure of the Quyuan plow.

The saddle, stirrup that is ready-made, it is quite simple to want to transform.

Quyuan ploughs are different and somewhat complicated for him.

Recalling the seventh-grade history textbook, the structure of the curved plough, finally, he remembered some clues.

"This way, and then again."

Dong Yao grabbed Cai Zhaoji's hand and sketched the shape of the Quyuan plough on the paper little by little.

It's a little out of shape, but it's better than before.

"It's a weird look."

Cai Zhaoji has also seen ploughing, but this is unheard of, unseen.

Or his own husband knows more, saddle, stirrups or something, and now he has made this kind of plough.

"Let's do this first, let people build it."

Dong Yao felt that it was already somewhat similar, as long as it was polished many times, the Quyuan plow would definitely come out.

"Master, Cao Cao's messenger has arrived, will you receive it?"

Zhao Tong came to the outside of the room and asked softly.

"What did he send an emissary for?"

Dong Yao tidied up his clothes slightly and stepped out of the room.

"In dismounting, meet the general."

When he arrived at the meeting place, Cao Cao's messenger stepped forward and bowed.

Ma Jun.

Hearing this name, Dong Yao almost called out, I am Chao, a great inventor.

"Are you Ma Deheng?"

"It's down."

Hearing the answer, Dong Yao was sure that this was the Cao Wei inventor.

It is said that the crossbow invented by Zhuge Liang was later improved by Ma Jun to make it more ox cups.

This man is also a talent, and even invents various things.

These include weaving machines, guide cars, and much more.

"General, is there anything wrong with being below, and why do you keep staring?"

"It's okay, I don't know what Cao Gong sent you for?"

Dong Yao was calculating in his heart how to leave Ma Jun behind.

Even if the person does not reach his peak, there are two brushes.

"Cao Gongzhi Great General captive... After migrating the people of Yuzhou, so many people who want to develop agriculture must be very laborious, so they specially sent an item to the next.

Ma Jun almost told the truth and hurriedly changed his words.

This is one of his shortcomings, not good at words.

If Cao Cao hadn't discovered his talent, he wouldn't know where to mess around now.

"Show me."

Dong Yao was a little puzzled, what kind of item was so mysterious.

Could it be a crossbow?

No, Zhuge Liang hasn't come out yet.

"Please look at the great general, Cao Gong said that if the great general likes it, he can exchange 10,000 high-grade war horses."

Ma Jun looked around before taking out a drawing from the cuff.

Dong Yao only glanced at it, and instantly recognized it, isn't this the plough he has been pondering recently.

This seems to be an advanced version of the coupling plow, a cow pulling the plow.

Even so, the gap compared to the Quyuan plow is a world of difference.

"Compared with the coupling plow, this plough greatly reduces human and animal power, and it is more convenient and faster to use, if the general likes it, the drawing will be given to you..." Before

Ma Jun finished speaking, the drawing was already in his hand.

This puzzled him very much, this is a tool for the benefit of the people.

After Cao Gong got this item, he couldn't sleep for several nights with excitement, why was Dong Yao indifferent?

Could it be that he has already written down the drawings and does not want to deliver 10,000 high-quality war horses?

But Cao Gong said that Dong Yao was indeed a scoundrel, but this kind of thing still couldn't be done.

"Cao Gong's ploughing is too manpower-intensive and animal power, I have more convenient ones."

Dong Yao now has a preliminary understanding of the Quyuan plow, why do you need to exchange ten thousand high-grade war horses for this ox plow.

Ma Jun was a little unconvinced, and the improvement of the coupling plow into a bull plough was already a breakthrough.

More powerful than that?

How can it be.

Dong Yao's expression was very serious, and he was quite confident in what he said.

This made him not only doubt, could it be true?

The transaction failed, Ma Jun wanted to come, but he wanted to see this more labor-saving and convenient plow.

Then he sent a letter to Cao Cao in Xuzhou.

"Impossible, absolutely impossible!"

Cao Cao received the letter and smiled with honey.

There is also a plough that can surpass a plough with an ox, he does not believe it, it is definitely Dong Yao who deceived him.

Seeing that Dong Yao was so insistent, he let Ma Jun stay there, and if he couldn't take it out at that time, he would lose the adult.
