Don't be a prince

Rejecting Tang Jian's suggestion without hesitation, Li Chengqian walked out slowly with the two of them, and asked as he walked: "Mr. Tang, I just want to ask, why did the Western Turks agree to this matter so casually? When Gu said that while hunting, he actually wanted to embarrass them, so that they would retreat. Whoever thought it was obviously embarrassing, they agreed in a daze."

Lu Kuan was also surprised and said: "Actually, I'm also very curious, Old Tang, tell me, you are the only one who knows about the Western Turks in Tang Dynasty, why are they so rash this time? You must know that there is actually a reason why we want them to marry the princess. It's meant to be a demonstration."

As the minister of Honglu Temple, Tang Jian naturally had a special understanding of the current situation in neighboring countries.

The three of them walked to Chengtian Gate, turned left and walked towards the East Palace.

It was not until entering the East Palace that Tang Jian saw that there was no one around, so he said: "His Royal Highness, Lu Shangshu, if you want to talk about why the Western Turks agreed, I have already said it in the court, but I didn't explain it in detail. Zhenguan In the early years, Tong Yehu Khan wanted to marry the princess of the Tang Dynasty to consolidate his status through marriage. He even thought about attacking the Eastern Turks together with the Tang Dynasty to take advantage of the opportunity.

Regardless of the strength of the Western Turks, Tong Yehu claimed that his achievements far surpassed the Khans of previous dynasties. In fact, compared to the Eastern Turks, the Western Turks were even more chaotic.The original Turkic was a military alliance composed of many tribes and tribes, which was mainly based on military conquest. The scattered nomadic economy led to political instability, internal strife among the ruling class and resistance of the oppressed nations. It is easy to form a split and separatist situation.

Because of this, during the Sui Dynasty, the Central Plains used alienation tactics against the Turks, and soon after the establishment of the Turkic Khanate, it split into two parts, east and west.Although Xieli of East Turkic also retained the Turkic aristocratic system, his words are still very useful.In comparison, Western Turks are much more chaotic.Although Tong Yehu is a great khan, he has limited control over his subordinates. "

The sun was very bright today, so the three of them did not enter the room, but stayed in a small pavilion in the East Palace.

The eunuchs and maids of the East Palace don't need to order, they also know what they should do.So when the three of them entered the small pavilion, a court lady immediately brought cushions.Shaking the blankets, the two eunuchs quickly blocked the position of the air vent on the pavilion to prevent the three of them from being blown by the cold wind.

A pot of hot tea is the most suitable time for Tang Jian who has talked a lot.

After taking a sip of tea, Tang Jian continued: "Because of this, Tong Yehu was eager to marry Datang, not only can the two countries form an alliance, but also strengthen his right to speak in Western Turkic. Whoever imagined it, Not only that, but in the first year of Zhenguan, Tong Yehu was killed by his uncle looking for an opportunity because he was too arbitrarily reforming the Western Turks.

In the second year of Zhenguan, the uncle of Tong Yehu Khan established himself as Moheduo Khan.Ashina Nishi Mohe set up a welcome and Li Teqin to protect Khan for Yibiboluo Siye.Si Yehu and Mo Hedu kept fighting each other, they each proposed to Tang Chao, hoping to get married and stabilize their positions.At that time, His Majesty retorted: "Your country is in chaos, the monarch and ministers are not settled, and the war is endless, so why talk about marriage."

The marriage failed this time, the two ignored His Majesty's reprimand and continued to attack each other.Last year, Mo Heduo was defeated and fled to the Altai Mountains, where he was killed by Ni Yi.All the ministries jointly promoted Si Yehu as the Great Khan of the Western Turks.Siyehu Khan conquered Tie Le in the north, but was defeated by Xue Yantuo Zhenzhu Khan.

This defeat was extremely detrimental to his rule.In addition, the Eastern Turks were killed by us, so he could only send envoys to the Tang Dynasty, hoping to use the Tang Dynasty to consolidate his prestige.For the current Si Yehu, as long as he can consolidate his position, he doesn't care if he is marrying a princess from the Tang Dynasty or going to the Tang Dynasty to marry a princess. "

Seeing that Tang Jian had finished speaking, Li Chengqian and Lu Kuan saluted together, thanking Tang Jian for his answer, but they still felt contemptuous in their hearts.It's so amazing to say so much about things that can be finished in a few sentences to show off your knowledge!

After each had a sip of tea, Lu Kuan looked at the eunuch who had put the brazier in the pavilion, and said, "Your Highness, I see that your subordinates in the East Palace seem to be very smart! I didn't see your order, and we just entered the pavilion. Some maids brought cushions, and eunuchs hung up blankets before the conversation was finished. Now that the conversation is over, even the brazier has been brought in."

When Lu Kuan said this, Tang Jian was also surprised.

They didn't enter the palace once or twice. Although the maids and eunuchs in the palace were also trained by the queen, their work efficiency was still not as good as that of the East Palace.The subordinates of the Eastern Palace are much more agile than those of the Imperial Palace.

Li Chengqian smiled, but did not answer.In fact, he has never taught the subordinates of the Eastern Palace. When he let them enter the Eastern Palace, he just told them to use their brains in everything, and don't have to be taught by the prince.That's all.

The brazier was burning very hot, and the sun was shining, so the three of them couldn't feel the cold even though they were outside.

Seeing Tang Jian and Lu Kuan simply chatting in the pavilion, Li Chengqian knew that the East Palace had to take care of the meal again.

I don't know if it was the emperor who made the news, or who made the news. Now all civil and military officials are very curious about the food in the East Palace.Tang Jian and Lu Kuan finally caught the opportunity, so naturally they would not let it go.

People are outside, and even though the sun is full today, it is still cold, so it is natural to have a meal of shabu-shabu.

The soup pot with butter and cornel, although not authentic, still made Tang Jian and Lu Kuan very addicted.

After eating, the two of them were already drinking and their steps were vain, so Li Chengqian could only order the guards of the East Palace to send them back.

After ordering the maids and eunuchs of the Eastern Palace to clean up the Yiqiu Palace, Li Chengqian went directly to the experimental base of the Engineering College.

It's just been a few days since I haven't seen it. The original wooden waterwheel has now become an iron one. But seeing Li Tai's dejected look by the water, Li Chengqian could only go to comfort him.

"Qingque, it's not a big deal to fail once or twice. You must know that every failure can provide you with a lot of experience. The most uncomfortable thing is actually false success. Think about it, if you only succeed after the promotion Isn’t it more uncomfortable if you want to rectify a fatal problem?”

"Brother Huang, I have not been defeated by failure, and now I am angry because of myself. Now the transmission part has been optimized to the limit by Yan Liben and the others. The only shortcoming here is the axle here. I have already used hundreds of axles made of steel, return it A lot of grease is added to lubricate, but there is still wear and tear. I don't know what to do anymore."

Seeing Li Tai beating his chest and stamping his feet, Li Chengqian smiled, patted Li Tai on the shoulder and said, "Actually, Brother Huang, I knew what to do at that time, but seeing how confident you are, I just can't bear to hit you. Come here , see how I solve this problem, Brother Huang."

Li Tai immediately became happy, and dragged Li Chengqian into the house.

On a piece of paper, Li Chengqian drew a schematic diagram of a roller bearing.

At the level of Datang craftsmen, ball bearings cannot be made, and roller bearings are still fine.What's more, it will be the old craftsmen who will be the supervisors who will make it. Even Li Chengqian, a later generation like Li Chengqian, can't fault their craftsmanship.

"If this thing is built, maybe it can really solve the problem!"

Yan Liben now has a strong ability to compose pictures in his brain. After imagining the scene where the roller bearing is made and applied, he feels that there is a lot to do!

Li Tai also thought about it, and couldn't help but blush: "Brother Huang, you're still smart, and I've been tinkering with you for so many days, but I still haven't figured out a way. As a result, you just looked at it, and you've already figured out a way."

Patting Li Tai on the shoulder, Li Chengqian said with a smile: "Actually, it has nothing to do with a person's intelligence, what is needed is experience. As long as you study more, Qingque, you can always catch up with your brother. Since you are very interested in these things How about studying how to use wind and convert it into power?"

"Use the wind?"

Li Tai just thought about it for a while, and then he thought of the time in the palace, when his brother brought the paper pinwheel he made.If you make something like this, maybe you can borrow the power of the wind!

Thinking of this, Li Tai was in a good mood, and immediately took a pen and paper to draw a picture to conceive.

Seeing that Li Tai was gone, Yan Liben sat down and said, "Your Highness, why are you lying to His Highness King Wei?"

"cheat?"

"If experience is really more effective than intelligence, then why are you always scolding me?"

"..."

This time there was no training, Li Chengqian stood up and kicked Yan Liben, and then walked away.

Some words can be said to the old man, but some words can only rot in his own stomach.As a descendant who traveled through time and led a team of lonely souls, many things were not because he was unwilling to show them, but because he couldn't show them.

Seeing that Li Tai lived happily here, and that the officials of Prince Wei's mansion had prepared a familiar residence for the prince, Li Chengqian no longer cared about it, but returned to the academy.

Li Dahai is very business-minded, and even built several houses for his family in a wasteland not far from the college.Although it still means living a little out of the crowd now, but when the surrounding area of ​​the academy becomes prosperous, he can make a lot of money from a place that doesn't seem to be far or near.If you keep holding the land firmly in your hands, even if your descendants fall, they will be able to get rich again in an instant.

"Calculate all the accounts, and you must be accurate. This time, the crown prince entrusted us with half of the money in the East Palace. If it goes wrong, don't say that the old man is ashamed to see the crown prince again, you all have to leave!"

Li Dahai had been a big shopkeeper outside the East Palace for a long time, and Li Dahai also had a bit of a temper. When Li Chengqian walked in, he happened to see Li Dahai holding a teapot in one hand and pointing Jiangshan.

Suddenly feeling a little cold on his back, Li Dahai was about to turn his head to see who was not closing the door winkingly, when he saw His Highness the Crown Prince with a smile on his lips.

The straight waist immediately bent down, Li Dahai hurriedly moved a chair, swept the dust that didn't exist on it with his sleeves, invited the prince to sit down and said, "Your Highness, why did you come here in person?"

Sitting on a chair, he waved his hand to those who were keeping accounts to continue.

Seeing them grabbing around with a lot of bamboo slices, Li Chengqian asked suspiciously: "Old Li, what are these people doing? Settling accounts? What are they doing with bamboo slices while calculating accounts?"

Li Dahai's eyes widened immediately, and he hesitated before saying, "Your Highness, could it be that you haven't learned calculation? If you want to learn calculation, the palace should arrange a professor from the Imperial College to teach you in the East Palace?"

"plan?"

Only now did Li Chengqian think of the old man who entered the East Palace with his head held high, but ran out with his face covered.At that time, I was discussing a problem with the old man, but after this guy came in, he bragged about how good he was at math.

Because he was busy asking the old man questions, Li Chengqian thought it was the accountant who was sent to the East Palace, so he asked him casually how much it would be if it was added to one hundred. After five thousand and fifty", they drove away directly.

Bastard, Gauss was able to calculate things when he was a child. He has a big beard, but he was stunned for a long time, and he still has the face to say that his calculations are unparalleled in the world?

But now that I think about it, could it be that that shameful old man is the mathematics professor of the Imperial College?

This....

Accidentally hit another one!

Li Chengqian couldn't bear to see those accountants holding bamboo slices and smoking their heads, and turned to Li Dahai and said, "You come with Gu, and Gu will teach you a new algorithm, which is much more convenient than calculating."

Calculating accounts with an abacus is definitely faster than calculating.

Although the usual money is about one thousand copper coins, the number of copper coins is very large, but as long as there is an abacus, how many accountants are needed?

Li Dahai couldn't guess what the prince would teach him, but as long as the prince taught him, he would be ecstatic, because he was sure that it must be a good thing.

The Institute of Engineering itself is a nest of craftsmen, whether it is blacksmiths, carpenters or masons, they all gather here now, and under Li Chengqian's order, they casually study things that they had no time and energy to study before.

The abacus is just a drawing, and it didn't take long for a carpenter from the engineering college to make it. The beads are the same size and polished brightly. No matter how you look at it, it is a big killer for counting.

Holding an account book, he explained to Li Dahai how to use the abacus, and it didn't take long for Li Dahai to fight.

The mental arithmetic ability of businessmen is actually very strong, but no matter how powerful the mental arithmetic ability is, it is useless when facing a series of ledgers.

It's all right now, with the abacus in hand, Li Dahai calculated the food expenses of the Institute of Engineering for this month in a short time.

Looking at the calculated numbers, Li Dahai was surprised to find that there was no difference at all.

With this thing, with the complicated account books in the Eastern Palace, how can there be so many accountants?I can figure it out in one day by myself!

After driving away the ecstatic Li Dahai, Li Chengqian began to think about whether to add math to the college's teaching programs.

It was proposed at the regular meeting of the college, and I thought it would be rejected, but who would have imagined that several old gentlemen immediately agreed.

Yang Du clapped his hands and said: "Numbering seems to have nothing to do with reading, but it is needed whether it is daily life or being an official. As long as it is the ability to settle down, I think I can teach it. The more than 1000 students in our college, I believe that there will not be many people who can become officials. Our college recruits students and establishes colleges under its jurisdiction. Not many people are needed. The rest of them go home, don’t they still have to plan food in the land?

For their future plans, we still have to teach them some methods.Knowing how to read and count, even if Xungui's family does not call in staff, they can still be hired by big merchants as shopkeepers.In this way, they learned from the old man and others, and we have an explanation to them. "

Yang Du's words caused all the old gentlemen to nod together.At the beginning, when he saw that his desire to educate the world had a chance to be realized, he was overjoyed for a while.As a result, more than 1000 students are now enrolled, and I can't help worrying about their future.

If you go to the academy to study for a while, but you still go back to dig the ground, wouldn't it be a waste of time?

"Since that's the case, then I'll go to the Imperial College and invite some teachers who teach arithmetic to add arithmetic to the students' homework. This way, you can relax a bit."

Chapter 222 Qu Yuanli

Li Chengqian is the only one who can sit up and walk.

After discussing with the old gentlemen to invite several gentlemen, Li Chengqian got into the carriage again and rushed back to Chang'an.

Although the road from Chang'an to the academy is as straight as possible and paved with concrete, it still takes more than an hour to go back and forth.

Stepping on the night, he was able to enter Chang'an City with the prince's token, and was warned by the city gate officer.

Chang'an's curfew is a law that makes this city different from other cities.The market is not allowed to open at night. If the officials of the square knowingly commit a crime, they will be exiled for three thousand miles.The circumstances are serious, and it is not uncommon to be beheaded.As for the city gate, only the Hongling Emergency Envoy and the Hundred Thousand Urgent Waist Card can open it.Although it is enough to open the city gate as a prince, the city gate officials still have to bear the responsibility.

After entering Chang'an City, there was no time to go to the Imperial College, so Li Chengqian could only go back to the East Palace and rest for a night.

The next day, Li Chengqian did not go directly to the Imperial College, but prepared a gift and posted a post to visit Kong Yingda's house.

Kong Yingda needs to go to court, so Kong Zhiyuan, the boss of their family, receives him.

Although Kong Zhiyuan was a professor at the Imperial College, he obviously hadn't seen any big scenes.The gift list of the East Palace made him feel at a loss for a moment, so he could only order the kitchen to prepare the noon banquet at any cost, so as not to dissatisfy the prince.

After appreciating countless calligraphy and paintings in Kong Yingda's study, Kong Yingda came back from court.Kong Zhiyuan breathed a sigh of relief when he heard that his father had returned.

"His Royal Highness is here, the old man is neglecting you, Zhiyuan, why don't you hurry up and prepare the banquet?"

Seeing that Kong Zhiyuan had slipped away, Li Chengqian picked up a pair of calligraphy on the desk and said with a smile: "Kong Jijiu's calligraphy is indeed called a master. Although Gu has practiced calligraphy for a long time, he can't write such words no matter what. Here comes Shen Yun."

"His Royal Highness loves you. Although the old man's handwriting is good, he can't form a school of his own no matter what. Let's not talk about this. Your Highness is here today. What advice do you have?"

After meeting, he directly flattered him, especially the title "Kong Jijiu", which made Kong Yingda feel like he was facing a formidable enemy.If the prediction is correct, the prince should have taken a fancy to the gentleman who the Imperial College didn't know, and was about to come over to poach the wall.

It would be fine if it was just digging on a daily basis, but now Lao Kong is holding a breath in his heart, no matter what, he doesn't want to be taken advantage of by the prince again.

You must know that the Guozijian originally taught the princes, but after the birth of Chongwenguan, the few princes and sons of the state all left.As a result, the Guozijian, which originally had more than 200 students, went to Loukong, and had to recruit some children of the Earl and Viscount.

If this were left in the past, how could they have the qualifications to enter the Imperial College!

Seeing that Kong Yingda was expressionless, but his beard was shaking, Li Chengqian didn't know what to do.

Regarding the matter of the Chongwen Museum and the college, I really feel sorry for Lao Kong.Not to mention Guozijian, even the Hongwen Museum is now desolate. Yao Silian went to the college to open his own branch of history, and now only Chu Liang, Cai Yungong, and Xiao Deyan are left to support them.

Arching his hands, Li Chengqian could only tell the truth: "Kong Jijiu, I came here this time to discuss with you. Can you send a few of the mathematics masters from the Imperial College to the academy? If the academy only teaches knowledge, those honorable ones It doesn’t matter if you are a noble child, if the students of common people cannot become officials, many of them will learn in vain. If you add arithmetic, even if they cannot become officials in the future, they will not lack a way out.”

Now Kong Yingda's eyes really turned red. If it wasn't the prince who came to the door today, he might really beat him out with a stick!

Too much deception!Too much deception! !Is it not enough to grab students?Now come to grab Mr.?Just merge the Imperial Academy into your academy!

Although her heart was overwhelmed, Kong Yingda had been in the officialdom for many years, and it was no problem to maintain a smiling face.

"Your Highness, it's not that the old man refuses to allow it. It's actually those gentlemen who studied mathematics. Even the old man can't order them. Instead of coming to the old man, His Highness, it is better to go directly to their house to ask. As long as they are willing, the old man will naturally agree. .”

Eyes are the windows to the soul. No matter how perfectly Kong Yingda conceals it, red eyes cannot deceive anyone.

Seeing that Lao Kong was really impatient, Li Chengqian didn't know what to do now.

Human beings are very strange. The simple guilt emotion has been accumulated for a long time. Not only will it not sublimate, but it will become slack, and it will even break the pot.

This was the case for Li Chengqian at this time. The establishment of the college was not only the long-cherished wish of the old gentlemen, but also his hope.Although Guozijian is known as the highest institution of learning, the professors are all the children of the nobles, and all the professors are Confucian classics.As a result, the students who came out were proficient in reciting poems and composing Fu, but once they became officials, they would show their true colors.

He Shou said at the beginning that he himself was born in the Imperial College, and after he became the county magistrate, he found that it was difficult to apply what he had learned in the past to governance.After wasting half his life, he finally found some way to the position of county magistrate.

If a serious person like He Shou is like this, let alone other county magistrates.It's no wonder that the officials who become governors all have a lot of beards. If they didn't thoroughly study the people's livelihood, who would dare to promote them?People who have just learned to walk run away. It is a strange thing if they do not harm the country and the people.

Having said that, there is no way to speak directly to Kong Yingda.Li Chengqian could only take out a picture from his arms and handed it to Kong Yingda, saying: "Since you can't convince them, why don't you give them this picture for Gu. After reading this picture, if they still don't want to come Academy, just act as if you have never been here before."

Kong Yingda took the drawing, not knowing what it meant, opened it and looked at it, only to see a lot of inexplicable pictures drawn on the paper, and some inexplicable words.

What "let the desired number be D", what "the result is E, minus B minus B and B minus four times the root of A and C, divide the double A, and choose one from E", it hurts people's head to see.

"Since your Highness said so, the old man will naturally bring the picture. However, if they are still unwilling after reading it, then the old man has nothing to do."

Li Chengqian nodded, then put down his calligraphy and painting, ready to leave.

Kong Yingda asked to stay, but Li Chengqian could only excuse that the college was busy and could not sit for a long time.

Lying on the carriage going back, Li Chengqian could only take a short nap.
