Everyone gathered around and glanced at the photocopied version of the "Building Construction Design Drawing" on the ground.

"What is this? Why doesn't the old man know the words on it? ”

Chen Xu was stunned for a moment, and suddenly remembered that simplified Chinese characters had not appeared in the Tang Dynasty, let alone Arabic numerals.

Thinking of this, Chen Xu said with a haha: "This is a simplified character created by the teacher, which evolved from the font of the Tang Dynasty. The only people in this world who know this kind of writing are my tutor and me. As for the latter string, it was learned by the family teacher from the Great Food, and it is called Arabic numerals. ”

As soon as they heard that it was the secret science of the teacher, everyone hid their faces and retreated, looking disrespectful.

Chen Xu was curious, so he asked, "Why are you like this?" Could it be that he looks down on the knowledge of his teacher? ”

Seeing that Chen Xu had some anger on his face, Du Ruhui arched his hand and stood up and explained: "Mr. Xiao misunderstood, since this book is a teacher's knowledge, without the permission of the master, it is no different from theft when I read it." ”

Hearing Du Ruhui say this, Chen Xu understood, dare to love these people in the Tang Dynasty are so well-behaved?

If it were placed in my own era, who would pay attention to these, you copy me, I copy yours, it is not uncommon.

If you are caught by the main owner, you will quibble. Say, can the things of the reader be called copying?

"I see, even if you take it and look at it, it's not much knowledge, and it doesn't hurt to take a look."

With the permission of his master, Li Er motioned for Du Ruhui to pick up the design drawings and hand them to his desk.

Li Er carefully held the drawings and gently turned the page.

But then, the look of surprise on his face disappeared.

It's not that it's lost, it's that it's not understood.

Li Er thinks that he is also a rich man, and he has read a lot of ancient law classics, but he has never seen such books.

Horizontal and vertical lines, all kinds of strange annotations.

What are the two verticals below this line? Is this crooked symbol on the horizontal line Arabic numerals? What do these represent?

Li Er flipped a few pages and was sweating profusely.

The more he looked at his head, the more confused he became, this was a new thing for him, not only could he not understand the words, but he could not even understand the picture above.

Li Er closed the drawings, closed his eyes and supported his forehead for a long time before eliminating the dizziness in his brain and asked Chen Xu: "Mr. Xiao, what kind of knowledge are these, why can't this king understand a word?" ”

Chen Xu put down the leg of mutton in his hand, wiped his hands, and saluted Li Er with a fist: "Back to Your Highness, this is a building construction design drawing, which is created by the family teacher and is the basic graphic for construction. ”

"If you want to understand this diagram, you must first learn simplified Chinese characters, numbers, physics, geometry, etc. It's easy to get started. If Your Highness wants to learn, I can teach you. ”

Physics? Geometry?

Li Erguang felt that his head was big just by hearing it, let alone studying.

What's more, learning is not something that can be achieved in a day or two, and he is still busy with political affairs, so he can't take care of anything else at all.

"This king really lacks skills, and there are still many matters in the palace that need to be handled by this king personally, and this king really has no chance to get this knowledge."

Chen Xu nodded, expressing his understanding very much, since he was going to be the emperor, he definitely couldn't be idle.

At this time, Du Ruhui quietly walked in front of Li Er, bowed down and said, "Your Highness, Weichen thinks that this kind of knowledge is superior. Since His Royal Highness is flawless, why not let the princes of the house try it? This is a godsend, and it's a rare opportunity! ”

Du Ruhui's words can be regarded as a reminder of Li Er.

yes, I don't have time to learn, but those bunnies in the backyard have a lot of time.

Li Er nodded, and said to Chen Xu under the seat: "This king has three sons, although he is still young, but he is very smart. If Mr. Chen doesn't dislike it, you might as well take a test of them, pick one or two out of them, and be your personal disciple? ”

Chen Xu was stunned for a moment, and said in his heart: "Okay, you Li Er, you really don't let go when you see the benefits." How dare your son provoke? One wants to rebel against you, the other wants to kill his brother, and the other doesn't do anything, but is killed by your eldest brother. Three unlucky people, who got into trouble with no one, didn't end well. ”

I just wanted to refuse, but I saw Li Er's eager eyes.

Only then did Chen Xu realize that his current situation was not very safe. When Li Er said this, he was not discussing with him.

Now that you have taken the task, there is no possibility of turning back.

Chen Xu sighed secretly, took a sip of wine and said, "Chen was able to pass on his education to the three princes today, and he is also fortunate to have three lives. ”

Soon, eight-year-old Li Chengqian, seven-and-a-half-year-old Li Ke and seven-year-old Li Tai walked in under the leadership of an old master.

I have to say that the royal education is really good, he has good manners at a young age, and respectfully salutes the bigwigs on both sides, and even Chen Xu, who has never met before, has also accepted their etiquette.

It's just that being bound so early will suppress their nature, and the unscrupulousness in adulthood may also be related to this education.

"Your Highness, the old man heard that someone was going to take the examination for the three princes, so he followed, wanting to see what a famous man he was, which could impress His Highness."

The old master, Kong Yingda, bowed to Li Er, and then turned to look at Chen Xu.

When he entered the house before, he saw Chen Xu at a glance.

He knew the rest of the people in the room, but Chen Xu, who ate a mouthful of oil, was a fresh face.

Could it be that he is the one who wants to take the examination for the princes' studies? But he was so young!

"Old man Kong Yingda, I don't know what Your Excellency is called?"

Kong Yingda?

Is it the great Confucian who has gone through four dynasties, Kong Yingda?

Chen Xu was a little surprised, he had to respect such a scholar.

So, he got up and wiped his hands, and gave a respectful salute.

"In Xia Chen Xu, I have seen the master."

Kong Yingda nodded and continued: "I heard that there are bachelors who want to take the examination of the three princes, could it be you?" ”

"It's down there!"

After Chen Xu finished speaking, he looked at the three little guys who were following behind Kong Yingda.

The brother is very recognizable, Li Chengqian's appearance is like Li Er, and he is taller than the other two.

Li Tai is tiger-headed and chubby.

Li Ke is very delicate and has fair skin, I don't know if he inherited his grandfather.

At the same time that Chen Xu was looking at his brother, Kong Yingda was also looking at him.

Different from Chen Xu's bad taste, Kong Yingda couldn't see through Chen Xu, and asked, "I don't know how old your Excellency is to be enlightened?" What scriptures have you studied? ”

Chen Xu retracted his gaze and turned to look at Kong Yingda, and couldn't help but scold in his heart: "Didn't you let Lao Tzu take the exam for your students?" Why did you take the school exam first? ”

Chen Xu understood that he was being looked down upon again.

"I was enlightened at the age of seven, and I didn't study any books."

Chen Xu sat down, and after speaking, he continued to deal with the leg of mutton on the plate.

Everyone present was surprised, and Kong Yingda even blew his beard and glared and asked, "You haven't even studied the classics?" Could it be Sima Xiangru's "Fan Jiang Chapter", Shi You's "Urgent Chapter", and Li Chang's "Yuan Shang Chapter". Haven't you learned any of this? ”

Chen Xu shook his head, let alone learning, he had never heard of these.

There was an uproar in the crowd, and even Li Er's eyes when he looked at Chen Xu changed, suspecting that he had lost his eyes.

"Then how are you enlightened?"

Kong Yingda was furious, his hands were clenched into fists, as long as Chen Xu couldn't speak, he would definitely slap Chen Xu hard, and then scold Li Erye.

Chen Xu rolled his eyes and thought for a long time before he said: "The multiplication formula table, as well as the "Three Character Classic", "Hundred Family Names", and "Disciple Rules". ”

Kong Yingda searched all the books he had read, but he never remembered these books, and then asked suspiciously: "Why are these classics unheard of?" ”

Chen Xu doesn't know what to say, these things only appeared after a thousand years, if you read it, Lao Tzu will definitely add you a WeChat.

Seeing that everyone present looked at him with disbelief, Chen Xu knew that if he didn't miss two hands, he was afraid that he would be regarded as a liar.

"Listen, I will recite this "Disciple Rules" again."

"Disciple rules, sage training. The first filial piety, the second sincere letter. Pan love the public, and kindness. If you have spare energy, you will learn ...... literature"

Chen Xu memorized the full text of "Disciple Rules" in one go, which was more serious than when the teacher forced him to recite it.

Kong Yingda twisted his beard, his mouth was wide open, and his expression was very shocked.

Li Er's reaction was also very fast, and almost the moment Chen Xu opened his mouth, he picked up his pen and began to record.

Until he stopped writing, he suddenly set off a huge wave in his heart.

Unexpectedly, there are such classic masterpieces in the world.

To say that he was still a little suspicious of Chen Xu's identity before, at this time, he was already convinced that Chen Xu was the son of a master in the world.
