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

Once there is, twice will get two, and twice will get four, four plus one will get five...

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

However, the result of snowballing is not satisfactory. Using this one as the base, it is already much worse by 30. It is known that thirty is calculated based on one this base, but thirty is completely wrong, and there are several missing points.

It took more than a year to make a series of corrections, and finally finished the minimum unit of one degree, but some half degree sine meter mixed with it.

After calculating the sine table, the cosine table is a process of replacing the reverse calculation by relying on "human flesh calculation chips". You only need to know how to make the square columns of nine numbers.

After the table was completed, it was immediately commended. Each person was given a scary bonus. Shi came forward to commend him again, and each person was given a second-class Jietianzhi Medal.

It was then published, and it is said that this booklet will be used in subjects such as stargazing, surveying and mapping, field division, artillery, etc.

The name of the gentleman also attracted heated discussion because of the "female" with the thick ink behind the name.

Others don’t need to calculate their work last night, and they just need to take out this booklet when they need it.

The gentleman felt that the day when this booklet was published was the most glorious moment in her life, because he told them: this booklet is enough for eternity. Unless one day there is a calculation or algorithm that allows any person to calculate any sinusoidal result, it will be used all the time, at most it will be corrected.

The gentleman thinks that this should be eternity. How could there be such a calculation method in the world that can directly calculate such a result? Wouldn't a calculation of nine numbers comparable to hundreds of people?

Whenever I see my name printed on the first page of the booklet, the gentleman will think of the origin of his name back then and can't help but smile.

This is something she can be proud of and definitely deserves to be proud of.

Although my younger brother may not understand the process very well, she still couldn't help but say it.

After hearing this, the prisoner Mi scratched her head and said, "Sister, as you say... aren't you no different from those weavers? My uncle said how to do it, the things you learned are tools like "looms", and then they are made into cotton... You are just brain-powered workers."

Although this was a joke, the gentleman snorted and cursed a few words. The prisoner Mi apologized and then passed.

Soon, the food and food came. The prisoner Mi picked up some dishes and asked, "Sister, why did you come here?"

"To test and draw some maps, we 'brained laborers' are needed. I'll come."

When the prisoner Mi heard that her sister was very concerned about this matter, she secretly stuck out her tongue, thinking that she could not say anything again.

He carefully coaxed him a few more words before asking again: "Did you come here on your own?"

The gentleman nodded and smiled, "I went to school and knew how big the world was. I didn't want to be cramped in the small village community."

"I want to go and see Mount Tai where the giants taught me how to guard the city in the book, I want to go and see the wasteland where cattle and sheep are seen with wind and grass, and I want to go and see the boundless sea..."

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

"It's still right to come forward to agree. He said that it's just to let the people of the world know that women may not be inferior to men. Since they have this intention, they should agree. Besides, I am also aware of the number of numbers, and I can't measure these things without them."

What she said was briefly, actually, the matter of mapping involves a lot of things, and many groups were divided into two groups, not just the group of Gao Liu.

On the premise of assuming that the earth under your feet is a ball, relying on the height angle of the purple microstar, we can calculate the distance of a certain degree, and thus infer the length of the meridian.

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

In addition to counting this, the group of the gentlemen came to Gaoliu in order to do something in the future.

Although the accuracy cannot be measured at this time, the latitude can be measured by relying on some simple instruments, compass and the North Star.

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

After mapping the latitude, using the metered drum cart to calculate the distance between the east and the west, you can roughly draw a map of later generations who are laughing at it, but at this time it can be regarded as a map of heaven.

There are rivers at the latitude, how far away is the high willows, how far away is it to the west and east, and where is the lake? These all need to be drawn, especially before the grassland tribes and the Central Plains are completely hostile. Even if they are inaccurate, they can provide a rough range - if they really fight, they will catch the grassland nobles in the place where there are lush lakes, rivers, water and grass. Most of them can catch them.

This is a very hard work, but once you achieve it, it will be a medal that will last for a hundred years, which will have a great impact on the future. Therefore, it is appropriate to make a decision to let the gentleman participate in it, thinking that in the future, people will know that there is a woman who may not be inferior to a man.

Some things cannot be said, even the younger brother cannot be said. The gentleman just introduced them roughly.

I picked up some other things. When I was having fun chatting, the door of the restaurant suddenly opened. A strong man walked in and shouted: "People Captain Mi!"

Both the siblings were stunned. The slander Mi stood up to respond. The strong man came over and took out a command and said, "If there is something urgent, I'll ask you to go back to the camp immediately."

The illegitimate prisoner Mi took it over and saw that it was an emergency order. She did not dare to neglect it. She hurriedly put it away, said a few more words to her sister, and hurriedly left.

…………

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

Many things have happened these days.

For example, these criminal prisoners brought by the illegitimate prisoners Mi, such as the confession that Que and Jun participated in it.

This is a big event, and it can cause trouble in Zhao's political situation.

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

Que and Jun were from the Gongzi Dynasty, so it was not convenient for Zhao Hou to directly support his son because many nobles in Zhao State supported Gongzi Zhang, and he was not able to pass the throne directly to his son, so he secretly supported his son to make friends with the nobles and expand his strength.

At this time, let the matter between Que and Jun be exposed, and the seriously ill Mr. Zhao must make a choice.

If you deal with Que and Jun, it would be like breaking your son's arm. Some people will probably stop dating their son when they see the news that something is wrong. If he does this, it would be like declaring his control and cannot surpass the nobles and the ministers in the palace. Once he dies, as long as these people support Gongzi Zhang, Gongzi Zhang's ascension will be as stable as Mount Tai.

Qu Jiang nodded and said, "How can I not know? The goods traded are not a problem, but where to trade? Will someone instigate them to raise prices? Will someone take the opportunity to cause trouble? All these must be considered. The first thing is to ensure that Solu Chan and others return to the Central Plains alive."

"Let's do this, choose some non-commissioned officers and elite warriors, organize more than a hundred people, go there first, stabilize them, and act as some deterrent. The Hu people who are close to us know our abilities, but I am afraid that those who are far away will not know how to live or die and will despise us."

"Immediately mobilize the iron pot, tea and cotton cloth needed. And... let the surveying and mapping people send a few people to follow. I'm going to do it sooner or later, so I might as well follow and take a look first."
