Rao was so self-deprecating, but when the result was finally calculated, the more than 20 people were still excited and didn't sleep all night.

If you have one, you will get two, and if you have two, you will get four, and if you add one, you will have five......

This one, like the first snowball in the snow, is getting bigger and bigger.

But the snowball result is not satisfactory, based on this one, when it is counted to thirty, it is already much worse. Thirty is known, but thirty can be calculated according to the basis of one, which is completely wrong, and it is several worse.

It took more than a year and a series of corrections to finally get the smallest unit of one degree, but with some half-degree sine watches.

After the sine table is calculated, the cosine table is the process of relying on the reverse calculation of "human flesh calculation", and it only needs to be able to open the square column with nine numbers.

After this table was completed, it was immediately commended, and everyone was given a somewhat scary amount of bonuses, and they came forward to commend it, and each person was awarded a second-class Xie Tianzhi medal.

It was then published, and it was said that this pamphlet would be used in subjects such as stargazing, surveying and mapping, field division, artillery, and so on.

The name of the gentleman, because of the "female" behind the name, attracted a heated discussion.

They didn't need to count their work last night, just take out this booklet and count it when they needed it.

Shu Junzi felt that the day this pamphlet was published was the most glorious moment of her life so far, because Shi told them that this pamphlet was enough for eternity, and unless one day there was an arithmetic chip or algorithm that could make any sine result for any person, it would always be used, and at most it would be corrected.

Shu Junzi thinks that this should be eternal, how can there be such an arithmetic algorithm between heaven and earth that can directly calculate such a result? Isn't that a nine-digit calculation comparable to hundreds or thousands of people?

Every time he saw his name printed on the first page of the booklet, he would think of the origin of his name and couldn't help but smile.

It's something she can be proud of, and definitely something she can be proud of.

Although her brother may not understand the process, she can't help but say it.

The captive was half-clear when he heard this, scratched his head and said, "Sister, according to what you say...... Aren't you no different from those weavers? Uncle said how to do it, the things you learn are tools like 'looms', and then make cotton cloth...... You're just a laborer with your brains. ”

Although this was a joke, the gentleman snorted and scolded a few words, and the prisoner apologized there, and then passed.

After a while, the wine and food were all here, and the prisoner took some dishes and sent them over, and asked, "Sister, why did you come here?" ”

"To draw some maps, we need to be 'brain-wielding laborers'. I'll just come here. ”

When she heard that her sister was very concerned about this matter, she secretly stuck out her tongue, and said that she should not say this in the future.

After a few more careful coaxing, he asked again: "You came on your own initiative?" ”

The gentleman nodded and said with a smile: "I went to the school and knew how big the world was, and I didn't want to be cramped in a small village at all. ”

"I want to see Mount Tai in the book, where the giant passed on the skills of birds and guards, I want to see the wasteland where the wind blows the grass and sees the cattle and sheep, and I want to see the boundless sea ......."

"It's just that it's not convenient for women to go to the mapping, after all, the journey is hard."

He said that he would let the world know that women are not necessarily inferior to men. If you have this heart, you should agree, and besides, I myself know nine numbers of geometry, and I can't measure without these things. ”

She said briefly, in fact, there are many things involved in the matter of mapping, and many groups have been divided, not just the group that came to Takayanagi.

On the premise of assuming that the earth under your feet is a ball, you should calculate the distance of one degree by relying on the altitude angle of the purple microstar, and deduce the length of the meridian from this.

Because of the precession, the North Star at this time is Ziwei, not Gouchen.

In addition to this, the group of gentlemen came to Takayanagi to do one thing in the future.

Although it is not possible to measure accuracy at this time, latitude can be measured with a few simple instruments, a compass, and the North Star.

While maintaining latitude, map a rough map of the northern grasslands. Because nomads need water and grass, and rivers and lakes are there, then the latitude is fixed.

After mapping the latitude, we can use a taxi drum car to measure the distance from east to west, and we can roughly draw a map that will be admired in the future, but can be counted as a heavenly work at this time.

How much is there a river at latitude, how far is it from Takayanagi, how far is it from west to east, and where is there a lake? These need to be mapped, especially before the grassland tribes and the Central Plains are completely hostile, even if it is not accurate, it can provide an approximate range - if you really want to fight, according to the lakes and rivers where there are abundant water and grass to catch the grassland nobles, nine times out of ten you can catch it.

This is quite a hard work, but once the achievement is a medal of merit for a hundred years, it will have a great impact on the future, so it is appropriate to let the gentleman participate in it, thinking that in the future people will know that there is a woman who is not necessarily inferior to a man.

There are some things that can't be said, even if it's his own brother, he can't say it, and the gentleman just gave a general introduction.

I picked up some other things, and when I was chatting, the door of the wine shop suddenly opened, and a strong man walked in and shouted: "Prisoner!" ”

The sister and brother were stunned, and the captive got up to respond, and the strong man came over, took out an order, and said, "There is an urgent matter, tell you to return to the camp immediately." ”

Shu took it over and took a look, and found that it was an urgent order, so he didn't dare to slack off, hurriedly put it away, said a few more words to his sister, and left in a hurry.

…………

In Gaoliu City, Qu Jiangzi looked at a letter and was silent.

A lot has happened in the past few days.

For example, these prisoners brought by Shu Prisoner, such as the confession in which Que and Jun participated.

This is a big event, a major event that can set off political waves in Zhao State.

As the leader of the Mo family here, he is well aware of the contradictions between those nobles of the Zhao State.

Que and Jun were from the Gongzi Dynasty, and it was inconvenient for Zhao Hou to directly support his son, because many nobles of Zhao supported Gongzi Zhang, and he was not good at passing on the throne directly to his son, so he secretly supported his son to make friends with the nobles and expand his power.

At this time, to poke out the matter of Que and Jun, the seriously ill Zhao Hou must make a choice.

If you deal with Que and Jun, it will be equivalent to cutting off your son's arm, and some people will see that the news is wrong, and I am afraid that they will no longer associate with their son - if he does this, it will be equivalent to declaring his control, and he will not be able to cross the nobles and palace ministers, then as soon as he dies, as long as these people support Gongzi Zhang, Gongzi Zhang's enthronement will be as stable as Mount Tai.

If it is not dealt with, it will attract a lot of criticism and contradictions. It is not a question of the law of the country or not, but in fact the dispute between cousins, which will be magnified. The court and some nobles are absolutely resentful of the words that everyone is equal under the law of the Mo family, and they may not care about what Que and Jun did.

However, if this matter can attack the Gongzi Dynasty, then this matter can be magnified, causing chaos and cutting off the help of the Gongzi Dynasty. The aristocrats didn't want to defend the law at all, they just wanted to use this incident to start an infighting.

It can be said that once this matter is poked out, Zhao Guo will inevitably be in chaos.

In case Zhao Hou couldn't hold on to death, a civil war in Zhao was inevitable. Gongzi Dynasty will not sit still, Wei has been supporting Gongzi Dynasty, and the Mo family is secretly helping Gongzi Zhang, light and dark.

What the Wei State supports, the Mo family must not support. And the strength of the Wei State can incur Gongzi Zhang to pay enough price and come up with enough chips in exchange for the support of the Mo family.

However, even such a big thing, in Qu Jiang's opinion, is not as good as the letter he is reading now.

The handwriting on the letter is the standard Mohist script, which cannot be faked.

The content inside is also very simple.

"I'm Solushen."

"I'm back."

"After returning from the westward journey, I learned that the prince of Qin was reinstated, expanded westward for many years, and started a war with Qiang, Zhai Rong, Wushi, and Yiqu. The original road is dangerous, and there is no way back. ”

"I went north from Yuzhi through the Yellow River, walked along the river, crossed Linhu, and was surrounded."

"Persuade Chief Hu to say that one person can exchange an iron pot, a pot of tea, and half a horse of silk and cotton. They will be suspicious, thinking that it is impossible for people to change the iron pot, how can people change the iron pot? But fortunately I was when I was younger, you know, I believed it. ”

"A total of nearly 500 iron pots, 500 jars of tea, and 300 horses of cotton cloth and silk."

"Quick change, I brought back five carts of books, and some Western craftsmen."

"Quick change!"

The latter inscription is Suo Lushen and his deputy, each with a seal, which is confirmed.

This letter was sent by several Hu people on the occasion of today's Gaoyanagi exchange market.

Compared with the disputes between those sons of Zhao State, Qu Jiangzi understands that this is a big deal, not to mention those elite and intelligent people who have traveled west for a long time, just those five cars of books are enough to be worth ten times the iron pot.

And plus those people, don't say ten times, even if it is a hundred times, if you want to come to the central side, you will try your best to switch back.

This is a transaction that does not need to be considered.

But how can the safety of these people be guaranteed?

Before Solu joined the Mo family, he was a well-known fraudster in Qi and Lu, and his tongue was strong, which was the foundation that could make Hu people believe in this transaction.

Although the letter is not shocking, but Qu Jiang can know the danger after a little thought, if it is replaced by someone else, who knows what will happen?

Since Qin Gongzilian returned to China with the help of Shenghui six years ago and successfully ascended the throne, he has expanded westward for many years, and since the war has started, it is impossible to return from the original route through Yiqu.

Fortunately, Suo Lushen was a bold and careful person, who traveled along the Yellow River and wanted to cross Linhu and return to the Central Plains through Zhao. This is a dangerous road, and only the wise and brave dare to take it.

This letter has been read many times, and the high-level leaders of the Mo family on Gaoyanagi's side have all been summoned, and the next person said: "Don't say five hundred, it is five thousand, and then it will be changed." If this thing is not done well, it will be a big mistake. The matter of Zhao Guo is just a trivial matter for the Mo family who wants to seek eternal life. This thing has to be done well. ”

Qu Jiang nodded and said, "How do I not know?" None of the goods traded are a problem, but where are they traded? Will someone instigate them to increase the price? Will someone take the opportunity to make trouble? All these must be taken into account, first of all, to ensure that Solushen and others return to the Central Plains alive. ”

"In this way, select some non-commissioned officers and elite warriors who are good at riding, organize more than 100 people, go over there first, stabilize them, and also do some deterrence. The Hu people who are close to us know our ability, but I am afraid that those who are far away will not know whether they are alive or dead, and despise us. ”

"Gather the iron pots, tea leaves, and cotton cloth you need at once. And also...... Let those who surveyed and mapped also send a few people to follow. Sooner or later, you might as well go out and have a look. ”

"The border fort is on guard, the mobile forces are gathered, and when it's time to trade, go and show off your might. Don't be afraid to spend food and money, for for these people, this money and food are nothing. What do you guys think? ”
