Datang: Huchi served as a bodyguard, but refused to enter the court as an official

Liu Bai chuckled, and said: "Your Majesty, this is the Liu family's family education, which was created by my father back then. The calculation is so simple that even children can calculate complex numbers!"

Arabic numerals were only introduced to the Central Plains after the Song Dynasty, so it doesn’t matter if I use it now, anyway, as long as something incomprehensible happens, it’s definitely right to push it on my cheap old man!

Li Er's expression softened immediately, replaced by a kind of respect.

"It turned out to be the knowledge passed down by Mr. Wen Yi, no wonder it is so obscure! Mr. Wen Yi was born a genius, it really makes me ashamed."

Now, his attitude towards that piece of paper became much gentler.

Even taking care to smooth out the creases on the paper.

Li Chengqian looked at his father with resentment, "Father, this is calculated by my servant."

Li Er snorted, and said: "Good knowledge, you have covered it with black bumps, if it is not for Liu Bai's face, I will teach you a good lesson!"

Li Chengqian's face darkened, and he didn't want to speak at all.

It's wrong to do anything with yourself

"Liu Bai, come and explain this knowledge to me!"

Liu Bai arched his hands and said: "Liu Bai takes orders!"

After finishing speaking, he chatted and laughed with Li Er and left.

Looking at the backs of the two, Li Chengqian became more and more speechless. He yelled at the group of old men with white beards: "What are you still doing here? You can figure out a fart!"

Wen Daya smiled wryly and said: "His Royal Highness, the life and death of tens of millions of people are at stake, so don't dare to mess around!"

He still didn't believe it, the so-called 'knowledge' was as magical as Liu Bai said.

"What? You don't believe in the ability of the prince?"

"The humble minister dare not"

Li Chengqian raised his chin, "A bunch of trash, what use are you for?"

After speaking, he turned his head and left.

Xue Li and Li Yifu quickly followed.

Standing on the ground, Li Er's eyes became brighter and brighter as he listened to Liu Bai's introduction to "New Mathematical Sciences".

After he understood it, he ordered someone to fetch the Liu family's farmland book and did the calculations himself.

"Sure enough, it's 900 million stones, exactly!"

Li Er laughed loudly, folded up the result he had calculated, and put it in his arms.

"Your Majesty is a genius, Cheng Qian learned to multiply and divide, but it took more than a month!"

"Of course! How can that kid Chengqian compare to me?"

Li Er laughed again.

Looking at Li Er's appearance, Liu Bai himself was disgusted by the compliment he just said.

Ever heard of calculus?Ever heard of geometric figures?

A number that can be calculated by a formula takes up a whole sheet of paper, so what is there to be arrogant about?

But no way.

By myself, I always come up with some novelty, which is bound to be too eye-catching.

After a long time, maybe some people will treat themselves as monsters.

It is said that mathematics can open people's wisdom. After the academy opened mathematics courses, cultivated a group of little monsters, and researched shocking theories, he would not look so dazzling.

Only when there are more small fish and shrimps on the sea surface, can the big sharks on the bottom of the sea be well hidden.

really!

After enjoying himself for a while, Li Er cleared his throat and said to Liu Bai: "Such a good knowledge is simple and practical, how about treating it as a course and teaching it to the students in the academy?"

As he said that, he smiled and said: "Of course, if you don't want to, I will take it back! But if you are willing, I will give you a great credit, and when you enter Chang'an in the future, I will take it with you!" reward!"

These days, the control of family education is extremely strict.

The reason why the five surnames and Qiwang have their current status is because they have inherited knowledge that is difficult for other families to match.

Since "New Mathematical Sciences" was created by Liu Yongnian, it is natural for Liu Bai to make the decision.

Liu Bai was just waiting for Li Er's words!

"Is there any reason why Liu Bai shouldn't? It's just that there are only Liu Bai and the crown prince who are proficient in new arithmetic. Liu Bai's family is busy with affairs, and I am afraid that only His Royal Highness the crown prince."

Li Er waved his big hand and said: "Then, after Chengqian recovers from his injury, go teach the students in the academy how to do arithmetic!"

Liu Bai snickered in his heart, on the surface he was as immovable as a mountain.

"Your Majesty is wise!"

Chapter 226 These days, stealing military power is a taboo, but stealing money is much easier

The people from the academy arrived, and the students started to go to the fields to collect food.

The gentlemen were not idle either. There was a large group of people, some lying on the ground digging potatoes, and some grinning and breaking corn.

Liu Bai didn't want to worry about them, so he called Li Chengqian and others back home.

study!

"Hand out!"

Liu Bai held the small board in one hand, grabbed Li Chengqian's neck with the other, and said viciously.

Li Chengqian stretched out his hand aggrievedly, and said, "It's for me too"

Snapped!

A board hit his palm hard!

hiss--

Li Chengqian gasped in pain, and hurriedly withdrew his hands and rubbed them vigorously.

Liu Bai's face sank, "Who told you to take it back?!"

Li Chengqian cried and said, "Brother Liu, I just want to show off in front of my father."

"Hand out!"

Li Chengqian could only stretch out his hand again.

slap, slap—

Every time he hit him, Li Chengqian would cry out in pain.

Xue Li, who was behind him, had long been used to this scene, holding his belly with both hands, and looking up at the roof.

But Li Yifu was an eye-opener.

Every time Li Chengqian cried out in pain, the flesh on his face would tremble.

His Royal Highness the crown prince, the future successor of Datang, can he teach him such a lesson?

What's more, Li Chengqian is still lame on one leg!

"My lord supervisor, His Royal Highness the Crown Prince already knew that he was wrong, do you think so?"

After hitting more than a dozen boards in a row, Li Yifu couldn't bear it.

Liu Bai glanced at him expressionlessly, and said, "Why don't you replace him?"

Li Yifu quickly shook his head like a rattle.

Friendship is friendship, he doesn't want his hands to swell into pig's feet.

Too late to study!

pop-

After more than a dozen boards went down, Li Chengqian's hand became a whole circle bigger.

Liu Bai threw his palm on the ground and sat down angrily.

This is the second time for Li Chengqian to make decisions without authorization!

The last time, Li Yuan was invited to the Liu family's banquet.

This time, he showed Li Er the new arithmetic.

Although the matter is not big, this kind of atmosphere cannot be used to!

What if something goes wrong in the future?

He must be given a lesson that he will never forget, so that he can remember it long!

"In the past few days, you are not allowed to go back to your East Palace, stay at home and sweep the floor, when will you have a long memory, and when will you give up!"

Li Chengqian blew on his glowing red palms, and his whole face collapsed.

"Brother Liu, my injury is not healed yet."

Liu Bai narrowed his eyes and said, "What did you say?"

Li Chengqian shrank his neck immediately, "I didn't say anything, I started sweeping the floor in a while!"

"Next time, I'll break your other leg too!"

"Yes, Brother Liu said yes, I will never dare again"

Li Chengqian made a gesture to get the crutch, but Liu Bai stopped him with another wave of his hand.

"Don't be busy yet!"

After speaking, Liu Bai looked at Li Yifu.

Li Yifu suddenly felt excited.

"If there is an order from the superintendent, the students are bound to do so!"

He could see that His Royal Highness was more afraid of Liu Bai than the emperor!

Just now the emperor stared, the prince dared to refute a few words, but Liu Bai's stare frightened him into a quail.

Liu Bai's expression suddenly became a little pale.

"You go out first!"

As if being pardoned, Li Yifu hurriedly bowed, retreated from the study, and closed the door carefully before leaving.

Xue Li consciously stood at the door, guarding with Xu Chu one mile away.

He knew that Liu Bai must have something important to tell Li Chengqian.

"Chengqian, sit down!"

Li Chengqian took a sneak look at Liu Bai's face, and said in a nonchalant voice: "I, I still won't sit down."

"Sit down as soon as I tell you to sit down, how can there be so much nonsense!"

Li Chengqian hurriedly sat upright, putting on a solemn look.

"What do you think of Li Yifu?"

Li Chengqian did not expect Liu Bai to ask about Li Yifu.

He pondered for a while, and said: "I have a good relationship with Li Yifu. This pair of crutches was made for me. For him, I am quite at ease."

Liu Bai bowed his head in thought, and remained silent for a while.

Li Yifu is a well-known "human cat". It is not an exaggeration to say that he was the most treacherous official in the early Tang Dynasty.

After Wu Zetian proclaimed himself emperor, he formed a clique for personal gain, sold his official titles, and was regarded as a guy who did all kinds of bad things and never did good things.

However, he is still a child after all, and no one can guarantee what he will look like in the future after entering the academy.

Moreover, judging from his current performance, he did treat Li Chengqian as a bosom friend.

Seeing that Liu Bai was silent, Li Chengqian asked cautiously: "Brother Liu, is there anything unusual about Li Yifu?"

Liu Bai shook his head, "It takes a long time to see people's hearts. Now whether he is good or bad, there is no conclusion yet. However, it is better not to let him know about important things for the time being!"

Li Chengqian nodded thoughtfully.
