Looking at Li's appearance, Li Shimin knew very well in his heart that her mind was in Lishan, in addition to thinking about her imperial grandfather, maybe she wanted to find her imperial sister and her two little girls from the same door.

Li's quality is not small, and it doesn't seem like a word to run to other people's houses every day.

Looking at her stubborn posture, Li Shimin was very worried, afraid that this girl would not be able to control it in the future.

"After dealing with political affairs these days, I will take you to Lishan to pick up your imperial grandfather back to the palace for Chinese New Year's Eve."

Li Lizhi asked eagerly, "How many days?" ”

With another long sigh, Li Shimin said melancholy: "Three or two days." ”

"Well, the daughter will go back to accompany the queen mother first."

Her footsteps were excited, and the aggrieved and stubborn posture she had just had just been gone.

Li Shimin picked up a meat bun and found that the bun was already cold, and he was holding a piece of Zhongshu Province in his hand.

It is also to send troops to the capital to protect the palace, to build the Hexi Corridor, and to prepare for the imperial examination and the marriage of Chengqian in the coming year, and even the construction of the Jiucheng Palace can only be shelved.

As an emperor, he found that the money on hand was not enough.

The taxes in Guanzhong have been recovered, and the taxes in more remote places are still on the way.

suddenly thought of his son-in-law, Zhang Yang did not expand the workshop, the papermaking workshop has been almost two years, and it is still the same.

His life must be very rich now, and if he really wants to make a contribution to Sheji, he should return Lishan to me.

One day hang him in front of the Chengtian Gate, and then swallow all his family property.

Lishan, Zhang Yang let out a loud sneeze.

Shangguan Yi instructed: "The county marquis should pay attention to the cold and warmth. ”

Zhang Yang was holding a compass in his hand and comparing it to the angle of the sun, he tightened his clothes, "Obviously dressed very warmly." ”

Using the compass to compare the angle of the sun, he walked back and forth by the Weishui River.

Now there is a row of wooden stakes standing on the stage, and Zhang Yang has marked the shadow of each wooden stake, marking the line with the shadow of the vertical ground, watching the movement of the shadow of the wooden stake in the sun, and confirming the position of direct sunlight.

Shangguan Yi was very curious about this compass, "I heard that stargazing at night is the skill of strange people, and Zhang Shangshu can also deduce the stars during the day?" ”

Zhang Yang explained: "I only know a little about the stars, I just borrow the sun, moon and stars to make some markings. ”

"Chu Suiliang has been in the village for half a month, and he is often absent-minded when he hears the children in the village say that he is often absent-minded when teaching."

"Absent-minded?"

"Yes." Shangguan Yi said again: "I have also observed in Xia, this person always comes to Lishan to teach, and after he is busy with the teaching of the study, he goes to Mr. Ouyang Xun to ask for calligraphy. ”

Zhang Yang frowned and said, "It's time for the winter solstice?" ”

Two days before the winter solstice.

Yuan Tiangang's compass is still not very convenient to use, and the judgment of solar terms is not accurate, and it needs to be improved.

In the absence of so many precision instruments, many times the derivation of directions and seasons is an approximate number.

When the calendar is determined, the solar terms can also be determined.

It is a very heavy task to use this compass to reinterpret the calendar, not only to record the changes in the solar terms in a few years, but also to look at the records of previous decades.

This has nothing to do with the fact that the daughter-in-law has to calculate the latitude and longitude at the moment.

The more knowledge you have, the better.

There are many skills that are not pressing, and it is some to learn more.

The sundial needs to calculate the sunshine oblique angle according to the latitude and longitude, and the sunshine inclination angle is placed obliquely on the plane with this calculation.

Use the angle of inclination of the sundial to make up the angle of latitude and the height of the sun, so as to be level with the equator, so that it can be regarded as a normal sundial.

Shangguan Yi was puzzled: "Why did Zhang Shangshu ask about the solar terms again?" ”

Zhang Yang also looked at the compass, "This is related to calculating latitude and longitude, you may not understand, in fact, the place where we are can be expressed by latitude and longitude, so that even if you go out, you won't get lost." ”

"It's not difficult to tell the direction with the stars, it's hard to deduce the distance, what is this latitude and longitude?"

Shangguan Yi reads a lot, and most of his knowledge in this area is difficult for him.

As soon as the words changed, I almost forgot for a moment what I came to the county marquis for.

Zhang Yang found a clean stone and sat down, looked up at the position of the sun, and then at the shadow of the stake.

"County marquis, do you want to arrange other work for Chu Suiliang?"

It was also the arrangement of his father Chu Liang to let Chu Suiliang come to Lishan.

There are not many people like Chu Suiliang who have a certain degree of attainment in calligraphy.

Of course you can use it well.

Withholding his wages?

Maybe his family doesn't look down on the 100 yuan that Lishan gives a month.

When the shadow coincided with the reticle, Zhang Yang hurriedly made a position record, and used the known angle, the height of the stake and the length of the shadow, to calculate the angle that needed to be placed obliquely, and add it to 180 degrees.

This math problem is not too difficult.

Shangguan Yi watched Zhang Yang take out a thin rope and tie it to the stone vertically, and then use the other one to aim at the middle end of the rope.

Niu Chuang's underwear was very thick, the outer coat was covered with patches, and there were even a lot of conspicuous threads.

Everyone wears it like this in this cold winter, and as for the cotton clothes at home, they are all for the children to wear, and the adults are reluctant to use them.

He put his hands in his sleeves, shrunk his neck in the cold wind, leaned forward and whispered: "Brother Shangguan, what are you doing with the county marquis like this?" ”

"It's measuring the slope, and an old and experienced craftsman can know how much the wall or foundation has shifted with just this amount, which is wisdom."

Niu Chuang nodded with a tangled expression, and he saw another skill that he had never seen before.

After being quiet for a long time, I saw Zhang Yang holding a short carbon pen in his hand at the moment and writing words on the stone platform that others couldn't understand.

Niu Chuang asked again in a low voice, "Is this easy to learn?" ”

Shangguan Yi shook his head and smiled bitterly, "It's difficult to learn with Brother Niu's foundation, but if you can master some mathematical operations, it will be easy to master." ”

As soon as he heard that it was mathematics, Niu Chuang laughed more and more embarrassed, not to mention mathematics, now he can't even recognize all the words, so he can only follow the children at home to learn one or two words from time to time.

】

"Does Brother Shangguan know this skill?"

"It's not hard."

"When the children in the village learn, a certain family doesn't have to learn." For Niu Chuang, it has been more than 30 years, and it is not easy to pick it up now.

Instead of thinking about learning this, it is better to count on the children of the future.

"Brother Niu, I have confirmed the location, you can put it."

Hearing Zhang Yang's words, Niu Chuang waved his hand to let the prepared people carry the sundial to the stage.

Shangguan Yi was amazed by Zhang Yang's speed, and it would take at least a day to calculate that no matter how experienced a rich craftsman was, he had seen.

After thinking about it again, I felt that this thing was not difficult for Zhang Yang at all.

With his level of arithmetic, it only takes a few moments to calculate the tilt of a sundial.

Zhang Yang held the angle, Niu Chuang led people to gently put down the sundial, which was equal to the same angle of the stake Zhang Yang straightened the string and compared the error between the two.

After confirming that it was correct, he nodded and signaled that it could be fixed.

The sundial with a large grinding disc and a slender iron pestle pass through it, which can be regarded as a serious bell in the village.

I took another look at the booklet and looked at the calculation process. Confirm that there is no problem, and then rest assured.

God always doesn't let people arrange the weather according to the expected plan, and the day after the sundial is ready, it snows heavily in Guanzhong.

The plan to measure latitude and longitude had to be put on hold.

Little Bear always likes to roll in the snow, Xiao Wu scolded it more than once, and it was even more unscrupulous.

Because every time the bear rolls in the snow and comes back to the house, it gets wet and leans against it, which makes her very distressed.

After being left behind by Xiao Wushu, it would hide behind Xu Hui again.

While provoking Xiao Wu to be angry, he went to Xu Huixun to appease him.

Inexplicably, I feel that this bear is starting to scum.

After Li Yue glared at it, he obediently returned to the eaves.

No matter what he was messing around in front of Xiao Wu and Xu Hui, Xiao Xiong only dared not be presumptuous in front of the real hostess of the house, and lay on the ground motionless.

Xiao Wu was unhappy, at most, just a few harsh sentences.

If this hostess is not happy, she will go hungry.

Steamed eggs with bacon and some home-grown spinach.

Zhang Yang cleaned up the meat and vegetables at home, there are still a few green onions left in the backyard, the green onions will freeze in such a cold weather, dig out some of them and put them in the warehouse on the side for cultivation, if these green onions do not grow well, they will have to wait until the spring of the next year to have green onions to eat.

Aunt Yang came quickly, "The county marquis Zou Guogong and the emperor are too high." ”

Zhang Yang looked outside the courtyard, and the teacher and Li Yuan had already walked to the door, hurriedly washed their hands and went out to greet them.

Li Yuan stroked his beard and said, "It's the time of dinner, and I came to visit you when I passed by." ”

As he spoke, Li Yuan noticed Xu Hui again, "What a handsome girl." ”

Zhang Yang introduced: "This is Xu Xiaode's daughter, Xu Hui. ”

Xu Hui saluted sensibly, "I've seen two elders. ”

"Xu Xiaode? I have already heard about the affairs of the court, and it is also time for Erlang to rectify the rule of officials. ”

As he spoke, Li Yuan pulled Zhang Gongjin and sat down at the dinner table.

"I didn't know that Grandpa Huang was coming, and there was no meat and vegetables prepared at home, so I asked my aunt to arrange it."

Li Yuan waved his hand and said, "It's okay, it's all your own family can be hungry." ”

Zhang Gongjin's eyes glanced at the little bear, "This animal is getting taller and taller." ”

Hearing this, Zhang Yang took out a piece of jerky, and the little bear stood up greedily to be as high as his waist.

Snatching the jerky, it sits under the eaves and eats it with relish.

"This animal is meek, but it's a pity that it should have roared in the mountains and forests, but it became a ......"

"It has become my family's town house beast, and it can usually bring some prey from the mountains." Zhang Yang took over the words and said.

Seeing that he said so lightly, Zhang Gongjin said again: "I heard that you are reading some ancient books these days? ”

"Your Majesty asked me to read the book of sages and sages, and hoped that I would be a good person."

Li Yuan snorted coldly: "I'm right, I knew he would say that." ”

Zhang Gongjin took out a piece of silver cake, "I am willing to lose the bet." ”

Li Yuan smiled and said, "It seems that what I read is a book of sages, but in fact, what I read are all classics respected by the family, and I have the heart to deal with the family, but it's a pity that Xu Xiaode didn't understand it and was used by your kid." ”

"It turned out that the emperor was making a bet between me and the teacher."

Li Yuan didn't deny it, took a bowl of hot tea handed by Li Yue and drank it leisurely, "What do you think your teacher is, one of the most relied on strategists in the Qin Wangfu Erlang, he gave advice behind his back, and killed no fewer people than you kid." ”

Speaking of that year, Zhang Gongjin also sighed, "It's funny." ”

Li Yuan emphasized: "You master and apprentice are not good people, in the early years ago, you joined Wang Shichong, and later followed me, went to various places to quell the rebellion, took the three counties of Chuqiu, and entrenched in Yucheng, went to Henan Province to seem to be pacified, and behind your back caught the powerful heirs of all over the country as a threat, and stabilized the situation in Henan and Hedong. ”

"Zhang Yang, you are young and vigorous above the court, and you are tough-handed, I can also see that you are humble and often ask for advice, Yan Shigu offended you, you don't care, high performance excludes you, you don't retaliate, the eldest grandson Chong has a conflict with you, you never pay attention to it, and even the children of the scholar clan abuse you and spit on your Red Mansion."

"There are so many enemies at a young age, Zou Guogong, as your teacher, is very worried, and sometimes I don't understand if you are really so open-minded, or if you don't take your peers in your eyes at all."

Zhang Yang bowed and bowed slightly, "Let the teacher and the emperor worry about it." ”

Li Yuan snorted coldly: "You kid is messing around outside, Zou Guogong is worried about you, you should ask him more if there is anything in the future, while he is still in the ground." ”

In and out of these words, he Li Yuan saw very clearly, the conflict between Xu Xiaode and Lu Chengqing, others don't know, Zhang Gongjin must be able to understand who is using whom.

"Teacher, Xu Xiaode, like the students, can't see those flies and dogs living so rich in the world, this is not a use, it is our heart for justice."

Zhang Gongjin said in a deep voice: "I told you about a person at the beginning, do you remember?" ”

"The teacher is talking about Wang Qi?"

Zhang Gongjin closed his eyes and breathed steadily, nodded slowly: "Since Your Majesty ascended the throne, Wang Qi has followed Your Majesty's side, that year there was a shortage of officials in the court, and His Majesty let Gao Shilian enter the Ministry of Officials to preside over the appointment and dismissal of officials, and then let Wang Qi temporarily take the position of servant, and then give Yongning County Duke." ”

"This person did not value fame and fortune when he was young, but he was recommended by Li Gang to join the army, this person is a member of the Taiyuan Wang family, he is a child of a family but has no spirit of a child of a family, he has always been alone, and he can't get around the local gate valve when he opens the imperial examination, the local heroes, and the families from all over the world, these are all obstacles."

"The old man heard Shangguan Yi say that the matter between you and the prince is just a petty fight, if you want to deal with the family, you have to meet Wang Qi, he may be able to help you."

Zhang Yang said again: "But does Wang Jue have the world in mind, or is his heart for the family?" ”

Zhang Gongjin sighed, "When Emperor Wen of the former Sui was still in power, he was involved by his uncle several times to be beheaded, and he didn't know who he offended in the clan. ”

Xiao Wu and Xu Hui both entered the house and did not dare to disturb the conversation in the courtyard.

Zhang Yang said clearly: "It turns out that the teacher has a plan. ”

Li Yuan sighed with emotion: "You are his only disciple, and your three sons are all taken care of by you, and their lives are short, who is it if you don't plan for you?" ”

"What you're saying is that the teacher's worries are all for me."

"You kid don't think about retiring at the age of thirty all day long, being a teacher will end up with hatred, and being a disciple will not live long."
