Seeing that the ministers began to study what kind of dowry was appropriate, Li Chengqian suddenly had the feeling of lifting a stone and shooting himself in the foot.

In fact, it is not a big deal to ask for a Turkic wife, the point is, the key is....

When I said that to the envoy of the Western Turks, it was just to embarrass him, who would have thought that the Western Turks would really agree.

Li Daliang, the secretary of the Ministry of Industry, stood up again and reported on the construction of the cement official road from Xiazhou to Chang'an. In addition, he proposed to build a cement official road between Chang'an and Luoyang. Cement roads are much more convenient to maintain, unlike dirt official roads, where there is a flash flood or something, and it is easy to complain.

The emperor praised the idea, but pushed the start of construction until next year.

To kill the Eastern Turks, Datang is also doing its best, and now the treasury needs to slowly lick the wounds, and there is no way to launch such a project for the time being.

After the court meeting, Li Chengqian did not enter the harem or return to the academy, but hurried out.

Fortunately, Tang Jian was slowly discussing something with Lu Kuan, and did not go far.

"Tang Honglu, wait a minute!"

Hearing the prince's voice, Tang Jian hurriedly stood down, stopped talking to Lu Kuan, and waited for the prince to approach.

"Hehe, the prince came just in time, and the old man and Lu Kuan are discussing your marriage. Now that the treasury is empty, and the dowry is small, we don't have to lose the face of our Datang. Although His Majesty said that the Inner Government would contribute, the old man and others would make it too much, which would also make His Majesty feel distressed. So the old man thinks that it is better for you to have something in the East Palace, which also makes the dowry look a lot better, how about it? ”

How is it? Not how.

Seeing that Tang Jian looked like this, Li Chengqian wanted to beat him. The barren treasury in the early years of Zhenguan made these bigwigs in the court only break a copper plate into two halves. As long as they can save money for the treasury, they are willing to save other people's face, which is their own face, and they can also give it away. In this way, it has developed a habit for this group of bastards: as long as it can save money, then be cheeky and nonsense, yes.

"Tang Gong is joking, it has always been parents who give their sons and daughters a dowry and save a dowry, how can they change when they are lonely."

Without hesitation, he rejected Tang Jian's suggestion, Li Chengqian walked out slowly with the two of them, and asked as he went: "Tang Gong, I want to ask, why did the Western Turks agree to this matter so casually?" When he was hunting in the autumn, he said that, in fact, he wanted to embarrass them, so that they could retreat. Who thought that it was obviously embarrassing, and they agreed to it. ”

Lu Kuan was also surprised: "Actually, I'm also very curious, Old Tang, let's talk about it, let's count your understanding of the Western Turks in Datang, why are they so rash this time?" You must know that we want them to marry the princess, in fact, there is a layer of demonstration. ”

Tang Jian, as the secretary of Honglu Temple, naturally has a special understanding of the current situation of neighboring countries.

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

It wasn't until he entered the East Palace that Tang Jian saw that there was no one around, so he said: "His Royal Highness the Prince, Lu Shangshu, if you want to say why the Western Turks agreed, in fact, I have already said it in the court, but I didn't say it in detail." In the early years of Zhenguan, Tongye Hu Khan wanted to marry the princess of the Tang Dynasty and consolidate his position through marriage. even thought of fighting the Eastern Turks with Datang and taking the opportunity to take advantage of it.

Don't look at the strong national strength of the Western Turks, and the achievements of Tong Yehu are far beyond the previous khans, in fact, compared with the Eastern Turks, the Western Turks are even more chaotic. The original Turkic was a military alliance composed of many tribes and tribes, mainly based on military conquest, and the scattered nomadic economy led to its political instability, the infighting of the ruling class and the resistance of the oppressed peoples, and it was very easy to form a situation of division and separation.

Because of this, during the Sui Dynasty, the Central Plains used divisive tactics against the Turks, and soon after the establishment of the Turkic Khanate, it was divided into two parts, the east and the west. Although the Eastern Turkic Jieli also retained the Turkic aristocracy, his words were still very useful. In contrast, the Western Turks were much more chaotic. Don't look at Tong Ye Hu as a great khan, but he has limited control over his subordinates. ”

Today's day is very full, so the three of them did not enter the room, but stopped at a small pavilion in the East Palace.

The eunuchs and maids of the East Palace didn't need to be instructed, and they knew what they should do. So when the three of them entered the small pavilion, a palace maid immediately sent cushions. The two eunuchs shook their blankets and quickly blocked the direction of the wind outlet on the pavilion, so that the three of them would not be blown by the cold wind.

A pot of hot tea, at this time, is the most suitable for Tang Jian, who has spoken a lot.

After taking a sip of tea, Tang Jian continued: "Because of this, Tong Ye Hu is in a hurry to marry the Tang Dynasty, which can not only allow the two countries to form an alliance, but also strengthen his voice in the Western Turks. Who would have thought that he would be so stirred up by Jieli and failed to form a result. Not only that, in the first year of Zhenguan, Tong Yehu was killed by his uncle looking for an opportunity because his reform of the Western Turks was too arrogant.

In the second year of Zhenguan, the uncle of Tongyehu Khan established himself as Mohedu Khan. Ashina Ni Mo He set up a special service to welcome and establish a special service, which was to protect the Khan of Yibi Boluo. Ye Hu and Mo Helu fought against each other, and they each proposed to the Tang Dynasty, hoping to catch the marriage and stabilize their position. At that time, His Majesty refuted and said: Your country is in turmoil, the monarch and the minister are undecided, and the war is endless, so why should you talk about marriage.

This time the marriage failed, and the two ignored His Majesty's reprimand and still attacked each other. Last year, Mohedu was defeated and fled to the Altai Mountains, where he was killed by the mud. The various ministries jointly promoted Ye Hu as the Great Khan of the Western Turks. The Khan of the Wild Leaf Protector went north to Tiele, but was defeated by the Khan of Xue Yantuo Zhenzhu.

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 consolidate his prestige with the help of the Tang Dynasty. For the current Ye Hu, as long as he can consolidate his position, he will marry the princess of the Tang Dynasty or marry the princess of the Tang Dynasty. ”

Seeing that Tang Jian finished speaking, Li Chengqian and Lu Kuan saluted together, thanking Tang Jian for his answer, but they were still disdainful in their hearts. Obviously, you can finish things in three or two sentences, but you have to say so much to show off your knowledge, how amazing you know!

After each took a sip of tea, Lu Kuan looked at the eunuch who was putting a brazier in the pavilion and said, "Your Highness, Weichen looks at your subordinates in the East Palace, they seem to be very smart!" I didn't see your instructions, but we just entered the pavilion, a palace maid sent a cushion, and before the words were finished, a eunuch hung a blanket. Now that the conversation is over, even the brazier has been brought in. ”

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

They have not entered the palace once or twice, although the palace maids and eunuchs in the palace are also trained by the queen, but their work efficiency is still not as good as that of the East Palace. The subordinates of the East Palace don't know how much more agile than the ones in the Imperial Palace.

Li Chengqian smiled and did not answer. In fact, he never taught the subordinates of the East Palace, and after letting them enter the East Palace, he just told them to use their brains in everything, and they don't have to be taught by Prince Ben. That's all.

The brazier was burning very strongly, and the sun was full, so the three of them were outside, but they didn't feel a little cold.

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

I don't know if the emperor blew it out, or who blew it out, but now the civil and military officials are very curious about the food in the East Palace. Tang Jian and Lu Kuan finally seized the opportunity, so naturally they would not let it go.

People are outside, and although the sun is full today, it is still cold, so it is natural to eat shabu-shabu.

The butter soup pot, with dogwood, although it is spicy and not authentic, still makes Tang Jian and Lu Kuanda addicted.

After eating, the two of them were already drunk, and Li Chengqian could only order the guards of the East Palace to send the two back.

After instructing the palace maids and eunuchs of the East Palace to clean up the Yiqiu Palace, Li Chengqian went directly to the experimental base of the Institute of Engineering.

It's just been a few days since I saw it, and the original wooden waterwheel has now become iron, but seeing Li Tai's dejected appearance by the water, Li Chengqian can only go over to comfort him.

"Qingque, it's not a big deal to fail once or twice, you know, every failure can provide you with a lot of experience. The most uncomfortable thing is actually the false success, think about it, if there is a fatal problem after the promotion, and then want to rectify it, isn't it more uncomfortable? ”

"Brother Huang, I was not defeated by defeat, and now I am angry because of myself. Now the transmission part has been optimized to the limit by Yan Liben, and the only flaw is the axle here. I've made the axle out of hundreds of steels, and I've added a lot of grease to it, but it's still wearing. I don't know what to do. ”

Seeing Li Tai pounding his chest, Li Chengqian smiled, patted Li Tai on the shoulder and said, "Actually, Brother Huang, I had a way at that time, but I just saw that you were full of confidence, and I couldn't bear to hit you." Come over and see how I solve this problem, Brother Huang. ”

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

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

With the level of Datang craftsmen, ball bearings can't be made, and roller bearings are still fine. What's more, the ones who will make it will be the old craftsmen who will be the prisoners, and their craftsmanship will not be faulty even by Li Chengqian, a later generation.

"If you build this thing, you might be able to solve the problem!"

Yan Liben now has a strong ability to compose in his brain, and after fantasizing about the scene where the roller bearing is made and applied, he feels that there is a lot to be done!

Li Tai also thought about it for a while, and couldn't help blushing: "Brother Huang, you are still smart, your brother has been tinkering for so many days, and he hasn't come up with a way." As a result, you've already figured out how to do it just by looking at it. ”

Patting Li Tai on the shoulder, Li Chengqian smiled: "Actually, this has nothing to do with personal intelligence, what is needed is experience." As long as you study more, you can always catch up with your brother. Since you're interested in these things, why don't you study how to use the wind and turn it into power? ”

"Using the wind?"

Li Tai just thought about it for a while, and he thought of the palace period, when his brother brought a paper windmill made by himself. If you make something like this, you might be able to borrow wind power!

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

Seeing that Li Tai was gone, Yan Li sat down and said, "Your Highness, why are you deceiving His Royal Highness King Wei?" ”

"Liar?"

"If experience can really be more useful than smart, then why is Weichen always trained by you?"

“....”

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

Some things can be said to the old gentleman, and some words can only rot in his stomach. As a lonely soul who traveled through the later generations to lead the team, many things are not that he is unwilling to show them, but that he can't show them.

Seeing that Li Tai was living happily here, and that the subordinate officials of the Wei Wangfu had also prepared a familiar residence for the prince, Li Chengqian no longer cared, but returned to the academy.

Li Dahai is very business-minded, and even built a few rooms for his family in a wasteland not far from the college. Although it is still a bit of a secluded place now, when the surrounding area of the academy becomes prosperous, he can make a lot of money here, which seems to be not far away. If you keep the land firmly in your hands, even if your descendants decline, you can get rich again in an instant.

"All the accounts must be calculated clearly, and the text must be accurate. The prince has entrusted us with half of the money in the East Palace this time, if it is messed up, not to mention that the old man has no face to see the prince again, you all have to get out! ”

The big shopkeeper outside the East Palace has been in office for a long time, and Li Dahai also has a little temper, and when Li Chengqian walked in, he happened to see Li Dahai holding a teapot in one hand and pointing out the country.

Suddenly felt a little cold in his back, and Li Dahai was about to look back to see which one had not closed the door without eyes, when he saw His Royal Highness the Crown Prince with a smile on the corner of his mouth.

The straight waist immediately bent down, Li Dahai hurriedly moved a chair, swept the dust that did not exist on it with his sleeve, and said while inviting the prince to sit down: "Your Highness, why did you come here in person?" ”

Sitting in a chair, he waved his hand to signal those who were doing the bookkeeping to continue.

Seeing that they were grabbing a large handful of bamboo chips, Li Chengqian was puzzled: "Lao Li, what are these people doing?" Accounts? What are you doing while fiddling with bamboo chips? ”

Li Dahai's eyes immediately widened, and he hesitated for a moment before saying, "Your Highness, could it be that you haven't learned calculations?" If you are doing arithmetic, the palace should arrange for the professor of Guozijian to teach you in the East Palace? ”

"Planning?"

Only then 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 gentleman, but after this guy came in, he bragged about how good he was at arithmetic.

Because he was busy asking the old gentleman questions, Li Chengqian thought that this was the account room sent to the East Palace, so he casually asked him how much it was to add to one hundred, and when he saw that he was stunned for a long time, he said "Fifty one hundred and one is not five thousand and fifty", and then drove away directly.

Bastard, something that Gauss would have counted when he was a child, he had a lot of beard, but he was stunned for a long time, and he still had the face to say that his arithmetic was unparalleled in the world?

But now that I think about it, could it be that shameful old man who is the arithmetic professor of Guozijian?

This....

I accidentally hit another one!

Seeing the appearance of those bookkeepers holding bamboo chips with their heads full of smoke, Li Chengqian couldn't bear it, turned his head to Li Dahai and said: "You and Gu Lai, Gu teaches you a new algorithm, which is much more convenient than calculation." ”

Using an abacus to settle accounts is definitely faster than calculating, I don't know how much.

Although the money has always been about 1,000 copper coins, and the number is very large when you count copper coins, as long as you have an abacus, you can use so many account clerks?

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

The engineering college itself is a nest of craftsmen, whether it is a blacksmith, a carpenter or a mason, they are now gathered here, and under Li Chengqian's order, they can casually study things that they did not have the time and energy to study before.

The abacus is just a drawing, and it didn't take long for the carpenter of the engineering college to make it, and the beads are the same size, polished brightly, how to see how it is a big killer for counting.

took an account book and told Li Dahai how to use the abacus, and it didn't take long for Li Dahai to crackle.

Businessmen's mental arithmetic ability is actually very strong, but no matter how strong the mental arithmetic ability is, it will not come in handy in the face of one account book after another.

Now, with the abacus, it didn't take long for Li Dahai to calculate the cost of food in the College of Engineering for the past month.

Looking at the calculated numbers and counting them again, Li Dahai was surprised to find that there was nothing wrong with it.

With this thing, the complicated account books of the East Palace, how can you still need to invite so many bookkeepers? You can calculate it in one day by yourself!

Driving away the ecstatic Li Dahai, Li Chengqian began to think about whether to add counts to the college's teaching projects.

When it was brought up at the regular meeting of the academy, I thought it would be rejected, but I thought that a few old gentlemen immediately agreed.

Yang Du clapped his hands and said: "Counting seems to have nothing to do with reading, but whether it is daily life or being an official, it needs to be used." As long as it is the ability to settle down, the old man thinks he can teach it. Of the more than 1,000 students in our college, I believe that not many of them will be able to become officials, and it will not take many people for our college to recruit gentlemen and establish the colleges under its jurisdiction. When the rest of the people go home, don't they still have to dig in the land?

For their future plans, we still have to teach them some methods. is both literate and knows how to count, even if the Xungui family does not gather staff, they can be hired as shopkeepers by large merchants. In this way, they followed the old man and others to learn for a while, and we can be regarded as having an explanation for them. ”

Yang Du's words caused all the old gentlemen to nod together. When I saw that my desire to educate the world had a chance to be implemented, I got carried away for a while. As a result, more than 1,000 students are now enrolled, and I can't help but worry about their future.

If you go to the academy to study for a while, but you still go back to plowing the ground, wouldn't it be in vain?

"In that case, the boy will go to the country and ask some gentlemen who teach arithmetic to come and add arithmetic to the students' homework. In this way, you can also relax. ”
