Wei Gong is here?

For a while, all the civil and military officials in the entire court couldn't help but be stunned, and everyone's eyes were subconsciously looking at the door of the main hall.

"Wei Xianggong appeared at this time, should he ...... What does he have to report?"

"Perhaps, that's true!"

"Let's take a look, we'll find out later......

"Uh-huh......

In the hearts of all the civil and military officials, they secretly discussed to themselves, quietly waiting for Wei Zheng to enter the main hall, and then take a look.

But the Zheng family, the Lu family, and other family officials were panicked in their hearts at the moment.

"Wei Zheng appeared at this time, there must be no good news for us!"

Thinking so in everyone's hearts, Li Shimin had already waved his hand and ordered to go down, signaling to the father-in-law who came in at the door, and immediately let Wei Zheng enter the hall.

"The old minister sees the saint!" Wei Zheng arched his hand vigorously, and the whole person was so excited that he saluted.

As for the strange stares cast by the rest of the officials, Wei Zheng completely ignored them.

Thinking of the great benefits of the use of Arabic numerals for the entire Tang Kingdom, Wei Zheng was as excited as a navigator who discovered the New World.

Therefore, when he saluted, his whole body trembled slightly.

"Aiqing, hurry up." Li Shimin had never seen when Wei Zheng was so anxious, so when he saw Wei Zheng's trembling and hurried appearance, he was very puzzled in his heart, "Aiqing, what's wrong?" ”

"Back to the Holy One." Wei Zheng hurriedly got up, and a joyful smile suddenly appeared on his face, "The old minister has a major discovery to report to the Holy Lord, this matter is related to the national plan of the Tang Kingdom!" ”

"Huh?" Suddenly, not only Li Shimin was stunned, but even all the officials in the court were very puzzled in their hearts, and they were shocked beyond words.

Wei Zheng, all the officials in the Manchu court know that he never speaks.

And none of the things he did were not for the sake of the country.

Therefore, when they heard Wei Zheng say so hurriedly, everyone's pupils shrank, and their eyes stared at Wei Zheng like fine beaks.

Li Shimin, who was on the dragon chair, was also stunned and said: "Aiqing said quickly!" ”

"Yes." Wei Zheng nodded and smiled, then took out a booklet from his arms and presented it with both hands, "Holy Lord, this book is the premise of the development of the country's great plan, please take a look at it!" ”

"......" Li Shimin.

"......" Manchu civil and military.

However, for Wei Zheng's words, although they were speechless in their hearts, they still didn't dare to underestimate them.

"Bring it in." Li Shimin ordered Gonggong Gao.

"No." In response, Gonggong Gao picked up the booklet from Wei Zheng's hand with a puzzled head, and when he handed it to Li Shimin, he secretly glanced at it and found that it was written with the four big words 'Elementary Mathematics'.

"Isn't it, this elementary mathematics is the plan of the family and the country? Wei Gong, what's wrong with today? ”

"Did he take the wrong medicine?"

Although he was full of doubts in his heart, Gao Gonggong did not dare to be careless, but hurriedly presented the booklet of 'Elementary Mathematics' to Li Shimin.

Take a look.

The four words of elementary mathematics appeared in front of Li Shimin's eyes.

"......" The corners of Li Shimin's mouth twitched, he glanced up at Wei Zheng, and then opened the booklet, and what caught his eyes was unfamiliar Arabic numerals.

"What the hell is this???" Li Shimin frowned slightly and continued to look through.

On the back page, Li Shimin found a note on the side.

1 with one, 2 with two...... 10 with pickup.

And in the back, there are some simple calculations, which are similar to the existing arithmetic of the Tang Kingdom, except that the traditional numerical calculations have all become Arabic numerals for arithmetic.

"Hehe, interesting!" Li Shimin's eyebrows stretched, and he felt very interesting in his heart.

He had never seen anything like it in his life.

However, after thinking about it slightly, Li Shimin suddenly thought of why Wei Zheng said excitedly just now that this booklet is related to the country's plan!

Indeed, as Wei Zheng said.

If all the arithmetic of their Tang Kingdom was calculated by Arabic numerals, then a lot of troubles could be omitted, especially the departments of the Ministry of Rites.

Calculating taxes every year has become a big headache.

It didn't take months for them to calculate completely and inaccurately.

And with this number, the entire Tang Kingdom can apply what it has learned, and turn the copper coin into a fixed unit, which will not cause the copper coin to be exchanged for more than two silver sometimes, but often very little.

"Don't really say it, what kind of Arabic numerals are these, they are really wonderful!" Li Shimin sighed from the bottom of his heart.

But the hundreds of officials and people below saw Li Shimin frowning for a while, and then raising his eyebrows and smiling, which made them stunned, mainly because Wei Zheng remained silent.

"What kind of trouble is this damn going on!!

In the hearts of all officials, there is a sense of inexplicability.

If Yang Gongren's behavior just now made them feel strange, but the bad people also had a hands-on demonstration to let them know what it was, but Wei Zheng was good......

Since he entered the main hall, Wei Zheng has never spoken again.

They only saw Li Shimin on the dragon chair, his face moody.

"What the hell is it......

The officials panicked in their hearts.

But at this moment, Li Shimin finally finished reading the whole book, and then closed the booklet.

When he looked up at Wei Zheng, Li Shimin smiled with joy on his face, and asked out loud: "Aiqing really deserves to be my blessing, where did Aiqing get this elementary count?" ”

"Holy Lord, it was obtained by the old minister from Li Bo'an today." Wei Zheng replied with a deep breath.

"Oh? It was Li Bo'an who got it? Li Shimin was stunned, very incredible.

In the blink of an eye, with the doubts in his heart, he quickly opened the booklet and looked at the back of the elementary arithmetic, only to find that there was a line of big words written on it shamelessly:

Compiler of Elementary Mathematics: Vice President, Li Bo'an.

Li Shimin: "......"

Li Bo'an, this kid, didn't give this thing to me a long time ago? Actually sneaked him to the academy?

No, I'll have to settle the deal with him!

Thinking like this in his heart, Li Shimin looked at Wei Zheng and asked with a slight anger on his eyebrows: "Aiqing, where is Li Bo'an's kid!" Where is it now?! ”

......Seeing Li Shimin's appearance, Wei Zheng suddenly smiled in his heart, Li Bo'an, you kid didn't think about it, right? It's okay to pit the old man, now, the pit makes the saint angry...

"Holy Lord, Li Bo'an is teaching students in the academy now." Wei Zheng smiled and clenched his fists.

"Someone!" Li Shimin suddenly shouted, ready to order someone to call Li Yi to the court to scold him, but when he turned to think of the wonderful use of this thing, Li Shimin gave up and changed his words, "Give Wei Aiqing a seat!" ”

"Yes, Holy." Gonggong Gao was stunned for a moment, and immediately waved his hand to instruct, and a guard carried a seat into the court.

"Thank you, Holy Lord." Wei Zheng was stunned at first, and then he simply didn't feel polite, simply thanked Li Shimin, and sat aside.

This scene directly stunned the Manchu Dynasty civil and military.

At this moment, Li Shimin breathed a sigh of relief, handed the pamphlet to Gonggong Gao, and instructed: "Pass this elementary mathematics book to the hundred officials." ”

"No." Gonggong Gao nodded in confusion, took the booklet, and handed it to the eldest grandson Wuji first.

Fang Xuanling, who was on the side, with a puzzled mood, stepped forward directly to take a look.

The expressions of the two of them were the same as Li Shimin's frowning at first, and they were very surprised by the unfamiliar Arabic numerals, but after seeing the back, the two of them nodded in unison, looked at each other twice, and then looked down.

Not long after, after reading a book of elementary mathematics, the two of them let out a rough breath together, and their hearts were shocked.

"The emperor bless my Datang, congratulations to the saint, congratulations to the saint!" The eldest grandson Wuji and Fang Xuanling hugged their fists to congratulate Li Shimin, their eyes full of excitement.

"Hehe......" Li Shimin smiled and waved his hand, in a good mood, "Aiqing is exempt, this study is of great significance to my Datang, from now on, the two of you will also go to the academy to learn, you must learn this!" ”

"Yes, Holy." Fang Xuanling and the eldest grandson Wuji nodded in unison.

They didn't feel that there was anything to be ashamed of Li Shimin in letting them go to the academy to study this elementary mathematics.

The so-called learning sea is endless, and it is not ashamed to ask people.

Although this elementary mathematics seems to be a new science, the two of them know very well in their hearts that once this elementary mathematics is applied to the life of Tang Guo, this will be of infinite effect to Tang Guo!

It's better than killing a million enemies!

Because, through this elementary mathematics, the whole country can be invisibly strengthened, and at the same time, it can also facilitate the country's policy.

Not only that, but with elementary mathematics, the magic is completely unreasonable!

Whether it is for the country and the people, it is a rare good knowledge!

Therefore, the eldest grandson Wuji and Fang Xuanling agreed to Li Shimin's orders without hesitation.

"Li Bo'an, this kid, is simply the deputy general of the country!"

The two sighed in unison, and their eyes couldn't help but look at Li Jing with some jealousy.

Subsequently, the eldest grandson Wuji handed this elementary mathematics book to Li Jing's hand, and scolded with a joke: "Pharmacist, look at the good deeds done by this good man of your family!" ”

After the shock in their hearts disappeared, the two of them also had the same thoughts as Li Shimin in their hearts.

"Since you have this thing, why didn't you take it out sooner, that stinky boy of Li Bo'an? Why should it be implemented in the college first?"

"What a hateful fellow!"

Therefore, the eldest grandson Wuji and Fang Xuanling spilled the dissatisfaction in their hearts to Li Jing.

Li Jing's face was suddenly full of confusion and puzzlement.

However, due to the doubts and curiosity in his heart, Li Jing did not say much, but nodded and took the elementary mathematics, and then looked at it seriously.

I don't know if I don't see it, and I'm shocked when I see it!

"This thing...... Isn't that guy from Saburo, something that he is tinkering with on weekdays? How did it turn into an academic? Li Jing couldn't laugh or cry in his heart.

Before, Li Yi stayed in the house all day to tinker with these things, and the study was also full of these things, and he saw that Li Yi was still forcing Yue'er to study together, but Li Jing didn't care.

He originally thought that this was some kind of difficult book to understand, and according to Yue'er's temperament, he would definitely not be able to learn it.

But who would have thought ......

Damn, it's really a school book!

Moreover, the saint still let people learn?

"Ahem......" After reading this book, Li Jing hurriedly circulated the book to others.

Although Li Jing already knew this thing in his heart, when he looked at Li Shimin just now, it seemed that he was about to order someone to call Li Yi and scold him in public, Li Jing did not tell him honestly, he already knew these things, and he didn't care about it at the beginning.

"Congratulations to the Holy One." Li Jing just hugged his fists and congratulated Li Shimin just like the eldest grandson Wuji and Fang Xuanling.

But Li Shimin, Fang Xuanling, and the eldest grandson Wuji, seeing that Li Jing actually hugged his fists to congratulate, and this elementary mathematics was still written by Li Yi, the third lang of his family, and the corners of his mouth twitched for a while.

"Pharmacist, this matter ...... Did you know before that your Saburo would do this? Li Shimin asked faintly.

Since it is not possible to find Li Yi to be angry, it is better to send it to Li Jing.

But listening to Li Shimin's unhappy tone, and there was a sense of scolding, Li Jing knew that even if he wanted to hide now, he couldn't dodge.

He had no choice but to answer honestly.

"Holy Lord, Lao Chen has indeed seen it before, but Lao Chen doesn't know the wonderful use of this elementary mathematics." Li Jing clenched his fists in embarrassment.

"......" Li Shimin was speechless again.

He always had a bad feeling in his heart.

Inexplicably, it seems that he has been put on a table by Li Yi without knowing it.

Previously, because he didn't give the academy teachers, Li Shimin didn't expect that Li Yi, this guy, would take out elementary mathematics and let himself order hundreds of officials in public to let them go to the academy to study?

In this way, the teachers of the academy are suddenly available?

And Li Shimin also knew that Wei Zheng and them went to the academy to teach, although it was Li Li who interceded on the surface, but where would Li Shimin not know, it must be Li Yi's idea!

"Li Bo'an, this bastard boy, is simply very bad!"

Li Shimin scolded in his heart.

"Pharmacist, tell me, when and where did you know about elementary mathematics?" Li Shimin asked a little unwillingly, he had to figure out when he was put by Li Yi when he was put on the way.

"......" Li Jing was speechless for a moment, stunned, and then replied, "That is, a few days ago, the old minister saw Yue'er and studied under the pressure of San Lang. ”

......After a while, not only Li Shimin, but also the company commander Sun Wuji, Fang Xuanling, and Yang Gongren, who had watched elementary mathematics, were in a bad mood in an instant.

This special mother, they are even more learned than a servant girl?

And now, perhaps......

Once they go to the academy and find Li Bo'an to learn this elementary mathematics, they will be severely cheated by Li Bo'an!

This is Li Bo'an's purpose!

At this moment, they all understood it in their hearts.

But even if you blame Li Jing, what can you do?

That's it.

They have completely fallen for Li Bo'an's tricks......
