After another look, the daughter-in-law was reading the book intently.

From the hobby of mathematics to astronomy, this is almost what she has to study every day after meals, and she almost doesn't sleep every night and watches the sky at night.

Late at night, the couple lay on the bed.

Zhang Yang asked in a low voice, "Is there any movement of the little thing?" ”

Li Yue felt it carefully, "It seems to be there and it doesn't seem to be." ”

"It's really fake, how can I not feel it."

"It's not in the arms of my husband, how can I ......?"

At night, the couple was whispering, "Husband, don't make trouble, I have to teach the children tomorrow morning." ”

"Have you already figured out the derivative problem?"

Li Yue looked at her husband's face, her eyes dodging.

There was a burst of laughter in the room, and Li Yue said softly: "It's already enough." ”

Her red face was half-covered in the futon, and she grabbed the futon with both hands, "I just know how to calculate it, but I don't want to calculate it, I'm afraid that after the calculation, my husband will have nothing to teach me." ”

"How is it possible, you have to learn a lot, and when you learn to teach our children, for example, science, physics, I will teach them chemistry and geography."

After speaking, Zhang Yang blew out the oil lamp.

In the morning, when Zhang Yang woke up, Li Yue was sitting at the table in thin pajamas and writing.

Her pajamas and undergarment were made of fine silk fabric, like a layer of yarn and very hazy.

Zhang Yang looked out the window, today's sky is a little gloomy and sunless, it looks like it's going to rain, and the autumn rain in West China is coming.

After writing, Li Yue sat on the edge of the bed and opened a roll of paper, "Husband, let's see if it's right." ”

The derivative is calculated according to the linearity of the function, and when a function is infinitely close to zero, the rate of change is calculated.

It is also a derivative formula for a common function.

Li Yue sat on the edge of the bed with her head bowed, and put on a posture of letting herself preach, she was full of guilt in her heart after hiding this matter for so long.

"When was it calculated?"

"The husband has already calculated it half a month after the question, but he was not sure before, and after he secretly calculated it many times, he was able to deduce this derivation."

Zhang Yang looked at his daughter-in-law intently, and he couldn't accept the talent.

"Seeing that you admit your mistake and have such a sincere attitude, can my pocket money be increased, and the requirements are not high, sixty wen a day."

"No way!" Li Yue replied immediately.

"What not! Who made you keep it a secret. ”

"I still want my husband to teach me ......"

“……”

"Yikes!"

There was another commotion in the room, and the couple didn't stop until there was a knock on the door.

"Your Royal Highness, the children have arrived."

Li Yue straightened his hair and got off the bed, and straightened his clothes again, "Well, I know." ”

After speaking, she glared at Zhang Yang and took care of herself carefully.

After the couple got dressed and washed up, Zhang Yang went to open the door, and the aunt standing outside the door let the children enter the yard.

"Have you eaten them all?" Zhang Yang looked at this group of bear children.

"I haven't eaten yet." Li Zhixian said.

"Brother-in-law, I want to eat scallion duck."

This was said by Gao Yang.

Watching the children chirp into the house, this is a group of little devils.

Zhang Yang shook his head, "I'll eat scallion oil duck at noon, make breakfast for you first, and eat scallion oil eggs." ”

"I want to eat scallion pancakes!"

I don't know which of these children is opening, they are all Li Shimin's babies, and I don't know which ones are in life, they keep talking one by one, as if they will never have an end of saliva.

There were two aunts and Xiao Wu who helped Li Yue sort out some books for the children to read, and when Li Yue began to lecture, they quieted down.

Zhang Yang walked into his kitchen, and the breakfast of more than 20 children was a laborious job.

Cook a large bucket of rice and prepare today's dish.

The whole village of Lishan, including Lantian County, collected all the wheat this morning and handed it over to Lantian County to raise taxes, so that each family could take it back.

Lishan Village is a centralized production, you can put all the grain in one warehouse, and then get back enough grain for yourself, the excess grain is placed in six warehouses, and Shangguan Yi will hand over the silver money to the villagers.

Li Shimin looked at this process and asked, "Are you preparing to store the grain when you collect it?" ”

Shangguan Yi explained: "First, for taxes, and secondly, for grinding grain into rice and noodles, you can make other plans, and you can save a lot every year." ”

As he spoke, he pointed to dozens of small warehouses in the rear, and Shangguan Yi introduced: "The grain of previous years is also stored here, of course, these are all in case of emergency, and the excess will be sold to Chang'an City." ”

Li Shimin pondered, "Benefiting the villagers is a good means." ”

Shangguanyi introduced to Li Shimin the current governance methods in the village, everyone is a collective, and the wages of each family are not only food, but also the income of the factory.

Li Shimin also calculated, in addition to the men's efforts, women can also increase the family's income by working, according to Shangguan Yi, every family and husband and wife are working, and each family can get at least 100 yuan a month, which is something that is unthinkable if it is placed in other villages and counties.

Shangguan Yi talked about the marriage strategy in the village again, and Li Shimin was amused and interesting when he heard it.

"Let Your Majesty laugh, this kind of marriage method has also made a lot of jokes, so that people from the surrounding villages and counties also point fingers, but Doctor Sun agrees with this practice, a woman who marries after the age of twenty is the best age."

This reminded Li Shimin of Lizhen's marriage, which the queen is worried about now, and she doesn't want her to marry early.

Shangguan Yi said: "The county marquis has always insisted on this, the poor family married their daughters early, where can they wait until they are twenty years old, this is a problem faced by the village, there are very few women who have not married at the age of twenty." ”

"The DPRK and China are working together to boost the population, isn't Zhang Yang's approach the opposite?"

"Your Majesty, in fact, it is not necessarily the opposite, this year there are six families of men in Lishan, marriage has nothing to do with age, it is only about secular opinions, marrying a twenty-year-old woman is the same as a fifteen-year-old woman, compared to our Lishan men and women getting married, we care more about the views of both parties, and will not be forced to marry."

Speaking of this, Shangguan Yi sighed: "Of course, there are also three households who have come to Lishan this year, who made Lishan rich." ”

After talking with Shangguan Yi for a long time, Li Shimin was very interested in this person who ran away from Hongwen Pavilion and came to Lishan to follow Zhang Yang, and ran a dilapidated village into what it is now.

Zhang Yang will definitely not be able to do so many things alone, someone must be helping him.

Now Li Shimin has confirmed Shangguan Yi's ability.

Lishan is rich and sees the big from the small, and Li Shimin also realized that this practice of Lishan is only suitable for such a small place and small village.

If this is placed in a large place such as a local state capital, not only will it not have much effect, but it may also suffer from it.

This kind of collective work and distribution according to work is also worth studying.

In July, the entire city of Chang'an looked very dull.

In the palace, Li Chengqian was writing on a piece of music, and he was sweating profusely at the moment, and from time to time he had to stop his pen to wipe the sweat off his forehead.

The eunuch came with a bowl of herbal tea, "His Royal Highness the Prince, this is tea for the summer." ”

Li Chengqian picked up the tea bowl and drank it all, "These chapters that have been approved are taken to Zhongshu Province." ”

"Whoa."

Wiping off the sweat again, Li Chengqian drank the bitter herbal tea and looked at a piece of music, this is a piece sent by Luoyang, saying that a new pavilion has been built in Luoyang, and the people who enter and leave this pavilion are all noble people.

And the location is a lotus root land that the father gave to the green finch before.

I was curious, how could the officials of Luoyang submit this kind of recital, even if it was a person who came and went to Li Tai's place, it could only be said that Qingque had the heart to make friends with the children of the powerful?

It's nothing, it's just a matter of the younger generation.

Even if this matter comes to the father, the father will not care too much.

Not to mention a state affair, Li Chengqian wrote a letter to Luoyang to pay taxes on acres of land and sent this piece back.

Another Chinese scholar from Zhongshu Province hurriedly came, "His Royal Highness the Prince, Ashinadur has returned from the Western Regions, and he has also brought the lords of the four towns in the Western Regions, and there is a seal and a letter of state to present. ”

Thinking that Niu Jinda and General Li Daliang had also returned, Ashinadur went to Gaochang at the behest of his father last spring, and then went to the Western Regions.

The eldest grandson Wuji also walked quickly.

Li Chengqian was swaying at the moment, and when he saw the eldest grandson Wuji coming, it was as if he had seen a savior, "Does Zhao Guogong know that Ashina Duer has arrived outside the city?" ”

The eldest grandson Wuji bowed down and said, "The minister also knows." ”

"I don't know what Zhao Guogong thinks this matter should do." While talking, Li Chengqian also soaked a cloth towel in ice water, so that it could be much cooler when rubbed on his face.

The eldest grandson Wuji replied: "The minister thought that this would be undertaken by the Foreign Affairs Institute in advance, and Ashina Dur would be settled in the post house, and after the Foreign Affairs Yuan would undertake all the matters, he would report to His Royal Highness the Prince, and then make a decision in the court." ”

Li Chengqian nodded and said: "Zhao Guogong is right, but the Foreign Affairs Yuan has asked the officials of Zhongshu Province to make a record of the matter of welcoming Ashinadur, and I want to ask Xu Jingzong." ”

"The minister will arrange it."

In private, Li Chengqian is still willing to call the eldest grandson Wuji uncle, and he still calls Zhao Guogong on formal occasions in the palace.

Li Chengqian thought of the way the Foreign Affairs Yuan handled things.

I didn't think it before, but now looking at the Foreign Affairs Yuan from the standpoint of my father, Zhang Yang has always been very tough in presiding over diplomatic affairs, and at this time Li Chengqian is still worried about whether there will be an accident.

Although the Turks have gone to the general trend, the situation is still grim.

Especially after the defeat of Jieli, Ashinadur's department did not suffer a major injury, but retained its own strength.

This army should not be underestimated, and at this moment, Li Chengqian also deeply realized the difficulty of his father's position.

Unlike Zhang Yang, Xu Changyi will give some warnings more often.

is not as bold as Zhang Yang to make decisions.

Outside Chang'an City, Xu Jingzong and Zhang Daxiang stood at the gate of the city together to greet Ashinadur.

A group of war horses came in the distance, and when the Turkic soldiers and horses stopped in front of the city, Ashnadur, who was the leader, was looking around.

This Turkic Tiele was full of pride and disdain at the moment.

Xu Jingzong said loudly: "Please also ask Tiele to dismount and enter the city." ”

Ashinadur was still sitting on his horse, his chin was raised, his eyes were cloudy, and his yellow-brown face was full of distrust and suspicion.

"Please dismount!"

Xu Jingzong shouted loudly this time.

Du Yi pulled the reins and didn't mean to dismount at all, and he didn't know what to say.

Xu Jingzong asked the civil official on the side in a low voice, "What did he just say?" ”

"He said he only dismounted the real heroes."

Xu Jingzong hesitated: "Does he mean that this official is not a hero?" ”

The civil servant also smiled awkwardly.

In front of the city gate, the people of the Foreign Affairs House came opposite to Ashinadur, and the other party sat on the horse and never wanted to come down.

】

Another fast horse came, and someone handed a volume of letters to Xu Jingzong, "This is the words of the county marquis, and I also asked Xu Shilang to take a look." ”

Xu Jingzong took the letter and read it, then put away his eyes and became more decisive, and shouted, "Someone!" ”

The soldier in front of the city gate stepped forward, "What does Xu Shilang command?" ”

Xu Jingzong pointed to the war horse in front of him and shouted: "Cut the horse to this official!" ”

This made everyone hesitate a little, "Really?" ”

"Right in front of the city! A Turkic Tiele dared to shout in front of Chang'an City, who gave him the guts, cut it! ”

At the sound of an order, several soldiers rushed forward.

Before Ashinador could react, the knife flashed, and the knife edge stabbed into the horse's belly and cut horizontally.

The horse fell to the ground, kicking up a cloud of dust.

When the dust cleared, Ashinadur first stood up in embarrassment, and he saw his horse lying in a pool of blood, and he didn't even fully breathe.

To the people of the grassland, the war horse is like their family.

Ashinadur was furious, and he was about to rush to a few soldiers in front of him with a knife, and several people exchanged horizontal knives and collided with the scimitars of the grassland.

In less than a moment, Ashnadur was pushed to the ground.

Then hundreds of Turks followed Ashinadur to pull out their horizontal swords, pull up the reins, and the war horses raised their front hooves and were about to rush to Chang'an City.

"Presumptuous!" There was a loud shout from inside the city.

Li Daoyan rushed to the outside of the city with his soldiers and immediately blocked the city, and a large number of soldiers on the city wall had already drawn their bows and arrows to shoot the Turks under the city at any time.

The soldiers who rushed out were all holding Da Mo knives in their hands.

The sky was overcast and an autumn rain was about to fall, and the two sides in front of the city were tense.

Seeing Li Daoyan, Ashinadur was a little surprised at first, they had fought together in the Western Regions before, and he shouted loudly in Turkic dialect.

Zhang Daxiang couldn't stand it anymore and asked, "What is he talking about?" ”

"He said that we killed his war horse, and asked us to pay for our lives to resist his war horse."

"The Turks are all like this, and this Turkic Tiele is still so rebellious, it seems that the battle of Yinshan is still light."

Li Daoyan looked at these Turks, and then looked at Ashina Dur, "Dur, you can't be presumptuous in front of this Chang'an City. ”

"You're not in Tibet?"

Listening to Duer's words in Guanzhong, this made Xu Jingzong very stunned.

Li Daoyan replied: "Tubo has returned to obedience, and it is naturally back. ”
