Li Mi put on that woolen sweater. Then his eyes lit up. It seemed light and thin, but after putting it on, it was very comfortable and warm.

This woolen sweater is purely handmade. Every piece of wool is hand-sorted by Xu Hezi with a group of specially hired weavers, degreased, and then hand-woven.

In future generations, this is the real handmade luxury product. Gucci, Hermès and the like will be nothing in front of it.

"I'm afraid this business is not something that the two of us can afford." Although Li Mi couldn't immediately think of the situation of sheep eating people, he could still see the huge commercial value in it. Because so far, Datang has not yet

Begin to use wool maturely.

"Yes, so we need to find more partners."

After getting rid of Li Linfu, what Lu Xuan had to do was to fundamentally change the Tang Dynasty bit by bit and fulfill his wish to continue the prosperity of the Tang Dynasty.

But this is not a simple matter.

Just look at those time-travel novels. The vast majority of time-travelers have to first make friends with a few nobles of the Tang Dynasty to raise their starting point. Then they can change the people around them bit by bit, and then radiate to the surrounding areas.

society, until it changed the entire Tang Dynasty.

This is not just a matter of simple cool articles, but an obvious thing. That is, in this era, even if you have a large number of technical ideas that are beneficial to the country and the people, you may not be able to promote them.

Come.

Under the feudal era, certain things could only be promoted if the upper class saw the benefits. The Prince's Mansion was willing to promote the technology provided by Lu Xuan because those things could enhance the Prince's reputation. Now, Lu Xuan is preparing to gradually start implementing wool

In war, the top rulers must first see the benefits.

From ancient times to the present, all the policies promoted by any dynasty are good in intention. The land equalization system, the military system, and the military envoys are not policies that serve the country and the people. But in the end, they will all be distorted and dragged down.

collapsed and was eventually eliminated.

Because in the era of the feudal dynasty, the existence of the ruling class was aboveboard. The officials were all parents and officials...the power in their hands was even more unscrupulous. If these people did not get the benefits, they would find ways to get it themselves.

Therefore, no matter how good the plan or policy is, they will all fail in the end.

Lu Xuan was born in modern times and knew a key word, win-win. Although this word is essentially a kind of poisonous chicken soup, the kind used to add leeks. But in the feudal era, it was still effective, allowing the nobles to benefit.

, and then let them volunteer to promote something.

Li Mi acted very quickly, and with the help of the name of the Prince's Mansion, he quickly attracted a large number of nobles to join the wool business. Lu Xuan invested in the wool business with his technology and took half of the shares. They divided the rest among themselves.

With the benefits, these honorable nobles immediately became motivated. In less than a month, the first caravan set out to collect wool from the grassland.

In Chang'an City, An Lushan was very proud. He successfully obtained the position of the Jiedushi of Hedong. From then on, one person served as the Jiedushi of three places. His power was so high that no one else could be found in the entire Tang Dynasty.

Lu Xuan did not object to this in the end, and even secretly promoted it. The issue of Jiedushi was a national policy of the Tang Dynasty. So far, it has been very effective. Lu Xuan alone cannot shake this situation.

It is a national policy. Therefore, he can only use a darker method. That is to detonate this contradiction in advance.

Yes, Lu Xuan was prepared to force An Lushan to rebel and trigger the Anshi Rebellion in advance. Only when the princes in the court see the seriousness of this problem will they have the will to change.

If possible, Lu Xuan never wanted to start a civil war. Because no matter what, this civil war would hurt the Tang Dynasty itself. But at this time, there was actually no better way.

But when he thought about this, he suddenly realized that this was exactly the same as the method he used to deal with Li Linfu!! Well, this is a problem of the times, not my fault, Lu Xuan said to himself.

An Lushan left with great satisfaction. The caravan collecting wool could not come back in a short time. Lu Xuan fell into a state of doing nothing again. But this time, he did not continue to salt fish, but started to be busy.

stand up.

The first step was to determine and perfect the improvement of spindle technology. Xu Hezi was responsible for this. He just gave a brief explanation and then let it develop. Lu Xuan himself began to recall the useful knowledge in his brain and prepared to compile it into a book.

This can be said to be the most important thing he has done since he came to this era. Lu Xuan has no intention of dedicating himself to this era. What he hopes is to enjoy this era. But those things, if they are not changed,

, it is inevitable that there will be regrets in my heart. So, just sort out everything, plant the seeds one by one in this era, and let the era choose itself.

The first is mathematics, which is the basis of all industries. Lu Xuan, a social beast who has been in society for many years, can no longer remember much mathematics knowledge. The only thing that can be completely sorted out is the multiplication formula. The basics

Algebraic equations, and the simplest geometry.

In order to cooperate with geometry, he also made tools such as right-square ruler and compass.

It is worth noting that the above mathematical knowledge actually had its roots in this era, or even earlier. However, these things did not develop in the end.

This is because, in this era, these knowledges are the exclusive possessions of a family or a school of thought and are kept secret. The final result is that they are gradually buried in the long river of history.

Lu Xuan has no such scruples. What he wants is for this knowledge to spread and break the monopoly of that kind of knowledge. He doesn't even care about the consequences of this. In the process of dissemination of knowledge, he will choose to integrate into the world.

, or be eliminated by the world.

After more than a month, Lu Xuan finally completed his first book, "A Preliminary Explanation of Arithmetic".

The level of this book is probably between elementary school and junior middle school education in modern education. It starts with the multiplication formula and systematically introduces the calculation rules of addition, subtraction, multiplication and division. Then it briefly mentions the concept of equations. It’s not that he doesn’t want to write more.

, I actually almost forgot about it.

As for geometry, in addition to the use of simple collection tools, it also includes the Pythagorean theorem, various knowledge of circles, and various numerical calculation rules for various regular solids. Such as cubes, cylinders, cones, etc. These things

, all have important application value in modern society.

After spending another half a month perfecting various details, adding various illustrations and more detailed annotations, Lu Xuan's book, "A Preliminary Explanation of Arithmetic", was finally published.

Thanks to the emergence of movable type printing, book printing has become extremely common. But even so, "The First Interpretation of Arithmetic" still caused a moderate sensation in the Tang Dynasty.

In the Prince's Mansion, Li Heng and Li Mi played another game of chess after a long absence. On the chessboard, in front of Li Heng, was a book called "Elements of Arithmetic." He said in a slightly emotional tone.

"Look now, who still dares to believe that that person is a so-called barbarian from the Western Regions."

"The origin of Lieutenant Lu has always been a mystery. But at least he is loyal to the Tang Dynasty and to His Highness."

"It's true to be loyal to the Tang Dynasty, but it's not necessarily true to be loyal to me." There was an indescribable sour feeling in Li Heng's tone. He also noticed it himself. Lu Xuan never really cared about him.

.The only thing he cares about is this country, and even the people. Again, it feels like he regards the entire Tang Dynasty as his own.

"The Tang Dynasty belongs to His Highness. If you are loyal to the Tang Dynasty, you will naturally be loyal to Your Highness."
