"This is what Weichen should do, and he doesn't dare to be rewarded."

Cheng Yanjin hurriedly excused himself, and then said cautiously,

"The minister heard...... Your Majesty wants to send elite troops all the way to Wugong County? ”

Li Shimin raised his eyebrows slightly.

"Huh?"

He said with a little surprise,

"You're well-informed, aren't you...... That's what I mean. ”

"Jieli Khan's offensive line is roughly from martial arts, and I want to dispatch the elite all the way to kill his sharp spirit! It can also raise the prestige of our Tang Army. ”

Poof!

When Cheng Yanjin heard this, he immediately fell to his knees.

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

He pleaded,

"Please also ask Your Majesty to give the last general a chance!"

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

It won't be long before His Majesty will be knighted and sealed.

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

"Hmmm......"

Li Shimin groaned slightly and said,

"This road warrior, I originally wanted to take Wei Chi Gong as the vanguard, in terms of bravery, he is the best of the three armies, and no one is his opponent!"

"But since you want to go...... Then I will make you the vanguard of the right road, and respect the captain Chi Gong of the left vanguard, and meet the enemy together, how about it? ”

Cheng Yanjin's face was bitter.

"Huh? You have to respect Lao Hei, this ......"

There was a tangled look on his face.

"There is no child's play in the army, what is old and not old."

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

"If you don't want to, forgive it!"

"Wei Chi Gong led an army away, and it was no big deal."

Cheng Yanjin: "!! ”

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

He panicked in his heart, and hurriedly bowed his head and bowed,

"I am willing to respect the left vanguard and obey the dispatch."

When Li Shimin heard this, his expression softened slightly.

"That's it."

He waved his hand and said,

"Go back, the order will be delivered to you."

"The minister retired." Cheng Yanjin took a few steps back, turned around and left the Hall of Virtue.

Li Shimin got up slowly, his eyes flickering.

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

"Xu Aiqing is in the East Palace?"

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

"Yes."

Near the waiter,

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

Li Shimin nodded.

"Speaking of which, I may not have listened to his class in a long time."

He waved his hand and said,

"Call the Queen."

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

……

East Palace, South Study.

Li Chengqian, Li Tai and other students sat at their desks, facing a blank piece of paper and meditating.

The pen is about to be bitten, but it still can't be missed.

And on the hanging board in front, it is not a matter of the I Ching.

"It's so hard, am I stupid......"

"Humph! I don't believe that I can't make it up, I make it, I'll make it up! ”

"I can't do this question, I can't do it! It's so hard! Woowoo woo ......"

“……”

After a long silence, the little kids began to cry wolf.

The first to collapse was Li Tai, who claimed to be the smartest, but at the moment he had no clue about the problem, which made his frustration very strong.

Li Qingquan also frowned, looking suspicious of life.

And Li Chengqian and Li Ke had gloomy faces, and they were still stubbornly and violently solving the problem over there.

The most comfortable person in the audience was Li Liqian, because she couldn't understand it at all, so she was playing there......

"Eh, what's going on?"

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

"Why are you crying?"

"Has the gentleman punished you?"

Li Shimin also walked in, and he was a little surprised to see the children frowning.

What's wrong with this?

Are you all hit by the board?

"Father, mother, it's the brothers and sisters who can't do the question of the West Father!"

Li Lizhi got up and threw herself into the arms of the eldest grandson, and giggled.

When the emperor and queen heard this, they both raised their eyes to look.

I saw this sentence listed on the hanging board:

Today, there are chickens and rabbits in the same cage, there are thirty-five heads on the top, and ninety-four feet on the bottom.

"Chickens and rabbits?"

Li Shimin was slightly stunned and said,

"What's the problem?"

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

He hugged Xiao Lizhi, sat in her place, and picked up the pen with his hand.

The eldest grandson Wujian on the side also sat on one side, holding up his chin.

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

However, this one is hanging, but it is unwilling to fall.

Half an hour later.

Li Shimin and the eldest grandson Wujian are also entangled.

The eldest grandson Wujian scribbled and wrote, and it was already full of paper, while Li Er's side was still a blank piece of paper.

"What a problem is this!"

Li Shimin's face was a little hideous, he threw down the pen, and scolded,

"You can't just count it, it's a fart to make it so complicated!"

He was irritable because he had no ideas, but he was already red.

Wow.

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

Seeing Li Shimin and the eldest grandson Wuji, he just leaned over slightly, and he saluted.

Immediately, he looked at the students.

"Did anyone make it?"

Xu Fenglei glanced around and said jokingly,

"Look at your constipated expressions, it looks like you haven't made any of them."

"A word for you—"

"Stupid!"

Students: "#¥%......&*@"

Now their faces were even more bitter.

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

Master said that when you are beaten, you must stand upright......

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

Because they didn't do it either.

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

"Don't think that arithmetic is a strange skill, it is useless to learn, in fact, math is the foundation of all practical techniques!"

Xu Fenglei taught,

"For example, the two most important things for the country are money and food, which require a lot of math and can't go wrong! If you get it wrong, the finances of the whole country are wrong! ”

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

"The past generations have not paid attention to mathematics, which is really a great deviation! It's outrageous! ”

"As a prince and princess, the requirements for you as a teacher are not only limited to being a gentleman who upholds the right path, but to be involved in various disciplines, not to be proficient, but at least to understand!"

All the students nodded their heads one after another.

Li Shimin was also thoughtful.

Xu Fenglei's words can be regarded as a kind of admonition for him.

It is indeed a contradiction that the imperial court does not attach importance to mathematics, but it has to rely on it to gather money and grain.

"Let's just say that this chicken and rabbit are in the same cage, this question is very old, from "Sun Tzu's Sutra".

After Xu Fenglei finished talking about the concept of education, he began to solve the problem.

"In fact, there are many ways to solve this problem, and Sun Tzu used the foot cutting method back then."

"What is foot cutting? Let's look at ......"
