Inside the study.

"What? One person and one cow can plough two or three acres of land in one day? ”

The light in Cao Cao's eyes flickered suddenly, and he exclaimed.

Xun Yu and Jia Xu also stood up, their eyes shining, staring at Cao Bin.

Previously, three people and two cattle only cultivated acres of land in one day.

And the use of Quyuan plow, one person and one ox can plough two or three acres in one day.

In this way, the efficiency of the curved plough is at least ten times that of the existing coupling plow.

"Bin'er, are you serious? You didn't lie to your father, did you? ”

Cao Cao trembled all over, his face was full of excitement, and he asked in a trembling voice.

With a little calculation, he could calculate that if the plough were to be extended, the number of people under his current rule would be enough to open up ten times as much wasteland.

Even if the efficiency is reduced by only five or six times, won't the rice and wheat harvested in the coming year be at least five or six times as much?

This is a god plow!

"This data is calculated by my grandson, and it is not accurate, maybe it will be less, or maybe it will be more."

Cao Bin spread his hands and said helplessly: "But Sun Er firmly believes in one sentence, practice is the only criterion for testing the truth!" ”

"Just build the plough according to the drawings and try it in the field to get accurate data!"

"Does Father think so?"

In the era before he traveled, the manual curved plough had long been replaced by machinery, and he had not seen it with his own eyes.

It was only in the 'learning space' that I was taught by Liu Bowen, a teacher of academic literature, that I drew the drawings of this Quyuan plow.

Therefore, he did not know the specifics of the efficiency of this plough.

But that's okay, just give it a try and find out.

"Practice is the only criterion for testing truth? Although this is mediocre, it is full of the truth of the avenue under careful consideration, and it is a small word! ”

This was the first time Jia Xu spoke, but he was greatly amazed by what Cao Bin said.

Looking at Cao Bin, his gaze also changed from scrutiny to appreciation, with a bit of recognition.

"Haha, what my grandson said is very true, but the eldest father is confused."

When Cao Cao heard this, he smiled heartily, rolled up the drawings Zheng De, and put them in his arms.

"The eldest father immediately ordered someone to make this plow, and then he personally went down to the field to plow the land!"

Facing the gazes of everyone, he explained unhurriedly.

Speaking of which, although Lao Cao was born in a rich family and has never personally cultivated the fields, he attaches great importance to farming.

Therefore, for such sacred objects that can improve the efficiency of cultivated land, even if it is a forcible robbery, it is necessary to grab it.

Besides, this is what the grandson wants to offer, what are the grandparents doing when they see each other so much!

"My lord, I am willing to personally supervise the craftsman to build this plow, and never let it make any mistakes."

Jia Xu was also extremely excited, and even wanted to see the birth of this plow with his own eyes.

If the efficiency of this plough is true, then the lord can have five or even ten times more tuntian.

It won't be long before countless wastelands are cleared into fertile land.

In the meantime, the lord will no longer have the difficulty of food and grass shortage, and the people of the world will also get rid of poverty.

"No, I'm going to supervise it myself!"

Cao Cao refused without thinking about it, not because he couldn't believe Jia Xu, but because this plow was too important.

"The Lord has a lot of opportunities, and we will supervise such small matters."

Xun Yu also stood up, indicating that he was also very interested.

"Hmph, no matter how busy I am, I won't even have this little time."

Cao Cao clasped his hands to his chest, as if he was afraid that they would snatch the drawings by force.

"Father, and all of you, since I drew this map, I should be responsible for creating it."

Seeing that they seemed to be fighting for treasures, they almost started a fight, Cao Bin hurriedly said: "It just so happens that I have a workshop in my hand." ”

"Okay, Bin'er will be in charge, and after this plow is completed, the eldest father will gather all the ministers and personally go to the field to plow the land."

When Cao Cao heard this, he didn't object, so he just made up his mind.

Xun Yu and Jia Xu thought about it, and this is indeed the truth.

Moreover, as courtiers, how could they compete with the lord again and again?

"Lord, Gongzi Bin is smart, please recommend Gongzi Bin as Maocai!"

Jia Xu seemed to have made a decision, gritted his teeth, and said something that surprised everyone.

Filial piety is one of the ways in which the imperial court selects officials.

During the reign of Emperor Wu of the Han Dynasty, his edict ordered the county to raise filial piety and honesty and Maocai, that is, to raise filial piety and integrity.

Under normal circumstances, filial piety and honesty and Maocai are often confused into one subject, which belongs to the clear stream and is the right way for officials to be promoted.

After Emperor Wu of the Han Dynasty, until the end of the Eastern Han Dynasty, many celebrities and ministers were born with filial piety, which can be regarded as the most orthodox way of birth.

At this time, Jia Xu proposed to recommend Cao Bin as Maocai, which can be described as well-intentioned and bet on Cao Bin in advance.

Originally, such an approach was not in line with his usual cautious character.

But because he himself is a solid supporter of the eldest inheritance system, after confirming that Cao Bin is Cao Ang's widow and is indeed talented, he did not hesitate to bet.

"My lord, the last general agrees."

Xu Chu followed, looking at Cao Bin's eyes full of kindness.

He had a good relationship with Cao Ang in the past, and he had a congenital good impression of Cao Ang's son.

After listening to Cao Bin's high-minded talk, there is naturally no reason to be dissatisfied.

"The minister has no opinion."

Xun Yu frowned, and did not agree or object.

In his opinion, Cao Bin is still young now, and he is far from the time to become a leader.

Of course, he wouldn't be stupid enough to oppose it to his face.

"Lifting Maocai? Wen and you seriously? ”

Cao Cao's face was grim, and he asked in a deep voice.

No, this is not the Jia Wenhe I know.

In the past, he never interacted with others in private, nor did he climb to the powerful, which can be described as a model of self-preservation.

But what's going on now?

He even said that he wanted to recommend Cao Bin as Maocai!

"Back to the lord, the minister is indeed serious."

Jia Xu did not hesitate and said categorically.

Hearing his firm words, Cao Bin couldn't help but re-examine Jia Xu Jia Wenhe, who was known as the poisoner of the late Han Dynasty.

"Okay, according to what you say, I'm done."

Cao Cao glanced at Jia Xu seriously and nodded.

In the first half of this year, Situ Zhao Wen recommended Cao Pi as filial piety, but Cao Cao rejected him.

and thought that Zhao Wen's intentions were not pure, and he only recommended him because of Cao Pi's identity, and dismissed Zhao Wen.

And after five simulators to deduce the future, Cao Cao had another idea.

His grandson is indeed a great talent in both civil and military affairs, why do he avoid his relatives?

Since Jia Xu is willing to help his eldest grandson, how can he not agree?

"Wait, Father, and all of you, my grandson doesn't agree."

Seeing that they had arranged themselves in a few words, Cao Bin was suddenly unhappy.

"Huh?"

Cao Cao, Xun Yu, Jia Xu, and Xu Chu all had a question mark in their minds.

This... Did they hear it wrong, or did Cao Bin say the wrong thing in a moment of excitement?
