Den.

After listening to Cao Bin's eloquent words, Cao Cao, Xun Yu, Jia Xu, and Xu Chu were all silent.

There was a storm in their hearts, and they could not calm down for a long time.

First of all, this map of Kyushu has already given them a strong impact, which makes people shocked.

You must know that the maps of this era are very rough rough sketches, and they cannot be accurate to the counties and counties.

Even so, the Kanyu map is also the most confidential document, and ordinary people are not qualified to look at it.

However, the map that Cao Bin took out marked the size of each force's territory and the location of each state and county in great detail.

Although its accuracy has not yet been verified, the mere fact that it is well drawn has already overjoyed everyone.

Then, there is Cao Bin's analysis of the general trend of the world.

You must know that when the defeated Cao Cao retreated to Xudu in embarrassment, there was a lot of discussion in all parts of the world.

They seemed to have foreseen that the defeat in this battle would inevitably shake Cao Cao's rule.

And the families of the northern land watched coldly, counting on Cao Cao's fall, so that they could take advantage of it.

In fact, after returning to Xudu, Cao Cao convened all his advisers to discuss.

The ministers agreed that although the battle was lost, it was not too much of a defeat.

It was just the loss of some soldiers that interrupted the pace of unification in the south.

It's nothing, it's a big deal to bury your head in development, and you can fight again next year.

At most, it is a superficial injury, far from hurting the muscles and bones.

However, there are too few people in the world who have such a vision.

But I never thought that today I was actually broken by the eleven-year-old boy Cao Bin, which was really dumbfounded.

"Bin'er, where did you hear these words? Or did someone specifically tell you? ”

After a long time, Cao Cao came back from the shock, looked at Cao Bin with blazing eyes, and asked in a trembling voice.

"Well, no one told me, I figured it out myself."

Cao Bin spread his hands and replied.

This is, of course, the conclusion of my previous life as it seems in the history books.

But since I've crossed over, isn't that my own point of view?

No problem.

"Really?"

Cao Cao still didn't believe it.

"My grandson swears to the heavens that what I just said is true."

Cao Bin stretched out his right hand, pointed to the sky, and said solemnly.

"Okay, well, Father believes in you."

Cao Cao saw that his eyes were clear and did not dodge, so he believed his words.

Standing up, Cao Cao looked around at the books on the shelves and pulled out one casually.

When I looked at the cover, the word "Spring and Autumn" was written.

This is one of the six classics of Confucianism, which records the history of 12 generations of monarchs from Lu Yin Gong to Lu Ai Gong, totaling 244 years.

Each sentence implies the meaning of praise and disapproval, and is called 'Spring and Autumn Brushwork' and 'Micro Words and Righteousness' by later generations.

Of course, this scripture is also one of the must-read classics for students at this time.

"Can Bin'er read Spring and Autumn?"

Flipping through the book in his hand, Cao Cao asked casually.

"My grandson is like a stream!"

Cao Bin lowered his eyes slightly, but said proudly.

After getting the first reward of 'learning space', not only my physical fitness has been improved, but also my memory has been greatly improved.

If you read an ordinary book once, you can remember it; If you look at it three or five more times, you will be able to memorize it backwards and remember it forever.

"Oh, what does Zheng Boke Duan Yu Yan understand?"

When Cao Cao heard this, he didn't have much doubt.

He had long learned from the simulator that his eldest grandson had been very smart since he was a child, and it was not surprising that he could recite "Spring and Autumn".

"Shhhhh

But Xun Yu, Jia Xu, and Xu Chu were taken aback.

Cao Bin is only 11 years old.

At this age, when youth is budding and fun is in full swing, there are very few people who can sit down and read with peace of mind.

Not to mention memorizing one of the obscure Six Classics, "Spring and Autumn".

"At the beginning, Zheng Wugong married Yu Shen, called Wu Jiang, and gave birth to Zhuang Gong and Gongshu Duan; Zhuang Gong Kou Sheng, shocked Jiang Shi, so the name is called Kou Sheng, so he is evil; Love the uncle of the Communist Party and want to establish it; Urgently ask for Wu Gong, Gong Fu Xu..."

Hearing this, Cao Bin nodded, and recited the full text of Zheng Boke's allusion to Duan Yuyan.

"This allusion is about the past between Zheng Zhuang Gong and his brother Gongshu Duan thousands of years ago, in order to seize the throne of the monarch and the brothers were on the wall."

Subsequently, he explained: "Wu Jiang, the mother of Gong Zhuang, favored his younger brother Gongshu Duan, so that he could develop an arrogant and arrogant *** to seize the position of the monarch of the Duke of Zhuang, and Gong Zhuang was famous for his crusade against Gongshu Duan." Zhuang Gong complained about his mother's partiality, moved his mother to Yingdi, and was persuaded by Uncle Yingkao and others, and designed the mother and son to meet in Huangquan and get back together. ”

When Cao Cao heard this, he was overjoyed, and asked, "What is the solution to Cao Di's polemic?" ”

"In the spring of the tenth year, Qi Shi attacked me. Gong general battle, Cao Di, please see. The villagers said: 'Meat eaters seek it, what can they do'. He said: 'Meat eaters despise and fail to plan far. 'It's a see. Ask why you fight..."

Cao Bin did not hesitate, recited it directly, and explained: "This allusion also happened in the Zhuang Gong period, the tenth spring of Zhuang Gong..."

Cao Cao asked several times in a row, and he was able to recite and explain his meaning.

As soon as this conversation came out, Xun Yu, Jia Xu and others nodded in unison.

It can be seen that Cao Bin really recited "Spring and Autumn" and understood its meaning.

"It's good to be diligent in your studies."

Cao Cao nodded again and again when he heard this, his face was approving, and he was very satisfied with this eldest grandson.

He put the "Spring and Autumn" in his hand back to its original place, but saw a drawing on the table, which aroused his interest.

Cao Cao picked up the drawing, only to see a strange pattern drawn on it with a thin wolf hair.

It looks a bit like the coupling plough used by the common people to plough the land, but it is plausible.

The name of each part is marked next to it, as well as its size.

On the far right side of the drawing, there is a column of large block letters: Detailed explanation of Quyuan plow.

"Bin'er, what is painted in this picture?"

Just looking at the drawings but not the real thing, Lao Cao didn't even recognize what it was for a while.

"Father, the name of this picture is Quyuan Plow!"

Seeing that Lao Cao had already discovered the drawings, Cao Bin explained.

"Quyuan plow?"

Cao Cao's eyes flashed, as if he understood something.

"It is the zigzag plow, which is different from the coupling plough used by the people nowadays."

Cao Bin explained: "When my grandson was in Qian County, I saw people using coupling plows to plow the fields, and three people and two oxen could only plough a mu of land in one day, which was extremely inefficient. ”

"After that, my grandson meditated, improved it, and tried to draw this curved plow!"

"According to the grandson's estimate, this quyuan plough can be mastered by only one person, so that the power of an ox can plough two or three acres of land in a day, which can greatly accelerate the efficiency of cultivated land."

"The grandson learned that the eldest father called on the people to open up the wasteland, but suffered from the scarcity of agricultural tools and low efficiency, so he drew it and was preparing to dedicate it to the grandfather to share the worries of the eldest father!"

If you want to do a good job, you must first sharpen your tools.

Quyuan plow, which would have appeared only in the Li Tang Dynasty, was plagiarized by Cao Bin without hesitation.
