Li Shimin doesn't really want to start a war with Tuyuhun now, and now the Tang Dynasty is in ruins and wants to take good care of the national strength and accumulate strength.

But the land in the Hexi Corridor is very much what I want to get, it's not that I can't fight, but there is not much food in the DPRK now.

If this is the end of the country, what can be done.

I want the Hexi Corridor, but I don't want to pay too much.

Li Shimin smeared some cooling oil in distress.

A touch of cool oil looked much more refreshed, but it was a pity that those medical officers from the Imperial Medical Department couldn't figure out the formula for the cool tour.

Do you want to ask Li Zheng? Thinking of Li Zheng's smiling face, Li Shimin didn't want to go again.

Li Shimin opened his mouth and said: "Tomorrow morning, the Taiji Hall will discuss again." ”

After Fang Xuanling and Du Ruhui left, Li Shimin also knew that Li Zheng was going to open a academy.

"Your Majesty." The eunuch said again: "It is said that Zhao Guogong is also going to open another academy, saying that he wants to recruit more students from poor families. ”

Li Zheng is going to open a academy, and the eldest grandson Wuji is also going to open a academy again? It's an interesting thing.

Jingyang Li Zheng, infrastructure madman.

In front of a half-formed academy, more than a dozen children stood in front of Li Zheng.

These children are all from Jingyang Village, and they all look to be less than ten years old.

"Why are there only a few?" Li Zheng asked Li Yifu.

Li Yifu stood aside and said with a straight face: "Slightly older children have to help the family with farm work, how can they have spare time." ”

"What about the nearby villages?" Li Zheng asked.

Li Yifu sighed and said, "Things happened in a hurry, and the eldest grandson's family opened another academy. ”

Li Zheng: "So what? ”

Li Yifu: "So the children from the nearby villages have gone to the Changsun Academy in Chang'an, and it is cheaper to say that it is ten yuan a month." ”

Li Zheng nodded thoughtfully, "I see." ”

It seems that the robbery is robbery and can't be robbed, and the grandson family is famous and rich.

The children were from their own villages, and they were dressed in thin clothes.

Li Zheng opened his mouth and said, "I want to choose a squad leader among you, three team leaders." ”

"What's the squad leader?" A child asked.

"Good question, what's your name?" Li Zheng asked.

"My name is Da Niu."

Li Zheng nodded: "Da Niu, right, you will be the squad leader in the future, except for me, these children are under your control, you have to protect them well." ”

"Okay."

The big cow sat down obediently.

There was no blackboard these days, and Li Zheng was holding a stick and writing a number on the ground, "Let's start with numbers." ”

Li Zheng teaches children to recognize the numbers from one to nine.

Li Yifu watched from the sidelines, Li Zheng wrote words that he had never seen before.

It's not like it's scribbled, it's quite methodical.

In less than an hour, the children have known one to nine and can already write down.

These characters are very vivid, not as cumbersome as ordinary people's writing.

In half a day, Li Zheng had already taught them to know the addition and subtraction of numbers and single digits.

Li Yifu was surprised, how could these children learn so quickly?

After Li Zheng left, Li Yifu found a child who had just finished class.

Pointing to the watermill in the distance, he asked, "There should be a few waterwheels there." ”

"Six." The child answered.

"Six and six are how many." Li Yifu asked again.

The boy thought for a moment and said, "It should be twelve." ”

He didn't even have to count his fingers, he counted it out as soon as his brain passed.

A normal child should still count on his fingers.

Li Zheng's method has never been seen before, and it is true that Li Zheng's method can make mathematics very simple.

Early the next morning, Li Zheng was still teaching the children mathematics.

Li Yifu listened attentively, wondering how Li Zheng made arithmetic so simple.

At the end of another half-day lesson, the child has learned to add three single digits.

Li Yifu still couldn't understand how Li Zheng did it.

I really couldn't help my curiosity, Li Yifu found Li Zheng, "Jingyang Ling, how did you do it." ”

"What and how." Li Zheng said as he walked.

"How did you teach the kids math so quickly?"

If a ten-year-old child is placed in the next generation, he will already be in the third grade.

Li Zheng said to Li Yifu: "The children started too late, in fact, they already have some knowledge of numbers, and it is easy for me to teach." ”

"Is that so?" Li Yifu asked rhetorically.

Li Zheng raised his chin and said, "Of course, I think I was very proficient in addition, subtraction, multiplication and division when I was ten years old." ”

At night, Li Yifu was alone, specializing in Li Zheng's doorway.

I can't figure out the secret.

In the next few days, Li Yifu would go to audit every class of Li Zheng.

Ten days later, Li Zheng was already teaching multiplication formulas......

Looking at the multiplication formula table drawn by Li Zheng on the ground, Li Yifu's eyes were straight.

It's the first time I've seen someone who can teach math like this.

After reciting it a few times according to Li Zheng's method, Li Yifu immediately felt that this recitation method was very interesting.

One by one, one by two, two by two......

It's like a ballad in a minor key, and it's easy to remember.

I heard that Li Zheng unlocked the Nine Chapters of Mathematics.

But when he really saw how Li Zheng taught mathematics, Li Yifu felt that Li Chunfeng's generation was no more than Erer.

Wait until after the end of the lesson.

Li Yifu hurriedly erased the multiplication formula table on the ground.

"What's wrong with you?"

"These are all Jingyang Ling's skills, and you can't let others steal them. Don't teach anyone other than these disciples of your own. ”

In the next few days, Li Yifu found more than a dozen strong men in the village to guard the door.

As long as Li Zheng was giving a lecture to the children, the idlers were not allowed to approach.

Seeing that the academy was built, the academy was not big, and it was only a big house and a courtyard.

Territorial testing: 1,600 acres of territory, 13,600 population.

Mission Accomplished: Build a college

Reward: 8,000 tons of quicklime

New mission released: build 3,000 houses

Reward: Activate the second phase of the pharmacy

Li Zheng received the system task after completing the lecture. went to find Li Yifu.

Originally, the village was poor, and there were already so few people, and many houses were empty and in disrepair.

Thinking of building 3,000 houses, looking at the layout of the village now, one piece of land in the east and one room in the west, such a layout is not good.

In the future, more things will be built, and the village will not be able to vacate the place.

"What does Jingyang Ling order?" Li Yifu asked.

"I'm going to rebuild the village."

"How?"

Looking at the layout of the village now, Li Zheng said: "If you look at the village today, the layout of a piece of land in the east and a house in the west looks very scattered, and I plan to tidy it up." ”

As he spoke, Li Zheng drew a plot of land on the map, "Gather all the residents in this location and build them new houses." ”
