I directed the Xuanwumen Incident

Chapter 252 Give math lessons to the prince and princess, even Li Er can't?Everyone is stupid!

"This is what a humble official should do, and I dare not be rewarded."

Cheng Yaojin hastily declined, and then said cautiously,

"I heard... Your Majesty is going to send a group of elite soldiers to Wugong County?"

Li Shimin raised his eyebrows slightly.

"Ok?"

He was a little surprised and said,

"You are very well informed... I mean that."

"Jieli Khan's offensive line is generally based on martial arts. I want to dispatch elites along the way to kill his vigor! It can also enhance my Tang army's prestige."

Pfft!
When Cheng Yaojin heard the words, he immediately knelt down on the ground.

"Your Majesty, the last general is not talented, and I am willing to lead a group of soldiers to meet the enemy!"

He humbly begged,

"Your Majesty, please give the last general a chance!"

Cheng Yaojin also has his own little Jiujiu in his heart.

It won't be long before His Majesty will confer the title of Shiyi.

Naturally, he also wanted to take this opportunity to raise his combat achievements.

"Um……"

Li Shimin pondered for a while, and said,

"I wanted to use Yuchi Gong as the vanguard of this fierce soldier. In terms of bravery, he is the best in the three armies, and no one is his opponent!"

"But since you also want to go...then I will designate you as the vanguard on the right side, and respect the vanguard of the left, Yu Chi Gong, to meet the enemy together, how about that?"

Cheng Yaojin's face turned bitter.

"Ah? Respect Old Hei, this..."

There was a tangled look on his face.

"There is no child's play in the army. There is no such thing as old and black."

Li Shimin's expression became solemn, and he reprimanded,

"If you don't want to, then let it go!"

"It's okay for Yuchi Gong to lead an army away."

Cheng Yaojin: "!!!"

"Your Majesty's lesson is that the minister is guilty."

Panicked in his heart, he quickly bowed his head and bowed down,
"I would like to respect the left vanguard and obey the orders."

Li Shimin's expression softened a little when he heard this.

"That's it."

he waved,

"Go back, the transfer order will be sent to you."

"Resignation." Cheng Yaojin took a few steps back, turned and left the Xiande Hall.

Li Shimin stood up slowly, his eyes flickering.

How to deal with the Turks, he already has some strategies in his chest!

"Is Xu Aiqing in the East Palace?"

Li Er turned his head to look at the attendant at the side, and asked casually.

"exist."

Near the waiter said,

"Grand Xu is teaching the princes and princesses in the palace."

Li Shimin nodded.

"Speaking of which, maybe I haven't attended his class for a long time."

he waved,

"Call the queen."

"Go to his place for a while, and change your mind..."

……

East Palace, South Study Room.

Li Chengqian, Li Tai and other students sat at their desks, facing a blank sheet of paper and thinking hard.

The tip of the pen was almost bitten off, but there was still nothing left.

As for the front hanging board, it is not a problem with the Book of Changes.

"It's so difficult, am I an idiot..."

"Hmph! I don't believe it can't be made, I will make it, I will make it!"

"I can't do this question, I can't do it! It's too difficult! Woooooo..."

"..."

After a long silence, the little kids started to howl.

Li Tai was the first to collapse. He claimed to be the smartest, but at the moment he had no clue about the problem, which made him feel very frustrated.

Li Qingquan also frowned, looking suspicious of life.

On the other hand, Li Chengqian and Li Ke's faces were gloomy, and they were still solving stubborn and violent problems over there.

The most comfortable person in the audience was Li Lizhi, because she couldn't understand it at all, so she just left it there to play...

"Hey, what's the matter?"

The eldest grandson Wugou stepped into the south study room and said in surprise,

"Why are you crying?"

"Has the sir punished you?"

Li Shimin also walked in, and was somewhat surprised to see the children frowning.

What's wrong with this?
Are they all hit by the board?

"Royal father, queen mother, it's the elder brothers and sisters who can't solve Father Xi's problem!"

Li Lizhi got up and threw herself into the arms of her eldest grandson Wugou, giggling.

When the emperor and empress heard the words, they all raised their eyes.

I saw this sentence listed on the hanging board:

Today there are chickens and rabbits in the same cage, with 35 heads on the top and 94 feet on the bottom. How many are the chickens and rabbits?
"How many chickens and rabbits are there?"

Li Shimin was slightly taken aback, and said,
"What kind of question is this?"

"Let me think about it, let me think about it..."

He hugged Xiao Lizhi, sat on her seat, and picked up the pen.

The eldest grandson Wugou who was at the side also sat on one side, holding his chin up.

Seeing that the children are so distressed, as parents, they instinctively want to help the children solve their problems.

However, as soon as the pen was suspended, it was still unwilling to drop it.

After half an hour.

Li Shimin and his eldest grandson Wugou also had conflicted faces.

Changsun Wugou's scribbling and scribbling has already filled a piece of paper, while Li Er's side is still a blank sheet of paper.

"What a problem!"

Li Shimin's face was a little ferocious, he dropped his pen, and cursed,
"You can't just count it, it's useless to make it so complicated!"

He, who was irritable because he had no ideas, was already red and warm.

Dengdeng.

Xu Fenglei straightened his clothes and came out of the quiet room with a pot of tea in his arms.

Seeing Li Shimin and Changsun Wugou, he just bent down slightly, as a salute.

Immediately, he looked at the students.

"Has anyone made it?"

Xu Fenglei glanced around, jokingly said,
"You look constipated on your expressions, it seems that none of them have been made."

"I send you a word for the teacher——"

"stupid!"

Students: "#￥%...&*@"

Now they looked even more bitter.

Although I don't want to accept such comments, it is true that I can't do it.

Master said, you have to stand at attention when you are beaten...

However, as soon as his comments came out, even Li Shimin and his eldest grandson Wugou blushed.

Because neither of them did it.

So this comment can also be applied to them...

"Don't think that numerology is a strange skill, and it is useless to learn it. In fact, numerology is the foundation of all practical skills!"

Xu Fenglei taught,

"For example, the two most important items for the country, money and food, require a lot of mathematical calculations, and you can't make mistakes! Once you make a mistake, the entire country's finances will go wrong!"

"Not to mention, its importance in disciplines such as architecture, economics, geography, etc."

"It's a huge deviation in the past dynasties not to pay attention to numerology! It's a very outrageous thing!"

"As a prince and princess, what I ask of you as a teacher is not limited to being a gentleman who upholds the righteous way, but to be dabbled in various subjects. You don't want to be proficient, but at least you must understand!"

All the students nodded repeatedly.

Li Shimin was also thoughtful.

Xu Fenglei's words are also a kind of admonition to him.

It is indeed a contradiction that the imperial court does not pay much attention to numerology, but it must rely on it to collect money and food.

"Let's just talk about this question about chicken and rabbit in the same cage. This question is very old, and it comes from "Sun Tzu's Mathematical Classics."

After Xu Fenglei finished his educational philosophy, he started to solve the problem, saying,
"There are actually many solutions to this problem. The grandson used the method of chopping the feet back then."

"What do you mean by cutting off your feet? Let's see..."
