He understood that his status and official positions were closely related to the Mohist trade. The annual border tariffs provided a large amount of income for the King of Chu and was also part of the military expenditure of the New Army of Chu.

When I heard that Lechang Gorge was being built for more than half, I felt happy. I thought that I would have to deal with it in the future, so I reminded me a few words.

Another thing is because of the batch of arms bought by Linwujun. He didn't know the inside, so there was no problem with reporting normally. However, the prince's good husband patrols the border on behalf of the king, and Linwujun is also in the city. This is best to have a reminder.

If it is a normal transaction, it is easy to say; if it is a secret transaction, it is better to be careful.

Although he didn't know that the situation in Chu is surging now, he could probably feel it.

The caravan leader hurriedly thanked him, paid the full tariff according to the quantity of goods on the list, got the stamp, and asked the convoy to move forward faster and strive to arrive in Linwu tomorrow morning.

On the last few cars at the convoy, the gentleman who had graduated for one year was talking about some measurement knowledge with several "disciples" in the car.

She is young and a woman, but she is called Mr. She is somewhat unaccustomed to it.

After finishing my studies, I started measuring with some people who were not admitted to the school but had good level. This time I wanted to draw a picture of Jiuzhou. Si Shang spent a lot of effort and many people came out.

Three years ago, the disciples of the craftsmen who grinded crystals in the country finally grinded a thousand-mile mirror that could see the moons around the Taisui Star. After nearly two years of observation and recording, the knowledge of using the Taisui Star satellite as a timer to measure longitude and draw accurate maps has been sufficiently implemented, so today she brought her disciples to Linwu Pass.

At this time, when everyone was tired, a female disciple couldn't help but think of a gossip news that she heard and laughed: "Sir, have you heard that the prince and good husband of Chu State likes male style the most. It is said that the wife around her just gave birth to a son, and the people around her are all beautiful boys."

I just heard Linwu Siguan talk about the prince's good husband on behalf of the king's border. The female disciple's mind was full of scenes of two handsome men together.

The gentleman smiled and said, "The Chu nobles are so good at masculine style, and it is not something that only happens now. Why, do you like this kind of thing?"

The female disciple covered her mouth and smiled, "I don't like this. I think we went to Linwu. We can see the beautiful boys around Prince Liangfu and see if they were so beautiful."

The gentleman disdained: "Those who make money can be broken through the end of their wealth; those who make beauty can fall into love with each other. They can only rely on sleeping to get the favor of their masters. Even if such a person is born beautiful, I don't want to take a look at him."

"You are all women like me. You must learn more knowledge and will come from useful things. Even if jade is hidden in stone, it is also jade."

The female disciples hurriedly said yes, but thought in their hearts that I was not ugly. Besides, I would not find someone who was favored by princes and nobles, but I just looked at my skin.

How could they know that the gentleman's words were not only to educate them, but also to miss their little brother's return to the field.

When she returned from Zhaodi four years ago, she happened to catch up with the big debate among hundreds of schools, and her little brother's fate was also changed because of this debate.

Since elementary school, she has been doing the theory that the earth is round under her feet, and now the measurement work is based on that theory, so she is naturally very concerned about the debate.

The person who supported Gai Tian's theory at that time proposed a perfect model, called Qiheng and Liujian.

It is said that all the changes in spring, summer, autumn and winter are because the sun has seven orbits and constantly moves the orbits, so there are changes in spring, summer, autumn and winter.

Moreover, the sun is like a candle, and it cannot be seen when it is far away. Therefore, the height of the sun can be calculated by saying that the sun is one inch away, and the sun is far away because it is dark.

On the day of the summer solstice, the sun is running on the inner meter. Because the radius of the inner meter is very small, it is possible that the north of Sushen, the extreme north of the extreme north can be completely dark all day long.

When the sun is in the outer equilibrium, the extreme north will naturally be in the eternal night, because the sun is too far away, so it cannot be seen.

As for solar eclipse, it is because there is a dark star in the sky, which is running in the air, but is lower in height than the sun and the moon, so there are solar eclipses and lunar eclipses.

The debate about this model of heaven and earth is not just an academic debate, but an extremely serious political debate.

The sky is round and the earth is above and below. Under such a model, the hierarchy system is secretly in line with the way of heaven and earth. The heaven is noble and the earth is low, so the emperor can rule the Jiuzhou.

However, if the earth is round and the circle is equal everywhere, the upper and lower part are just a relative concept, so the legitimacy of the emperor was greatly impacted.

The strangeness of such a model is that it can explain spring, summer, autumn and winter, day and night, and even solar and lunar eclipses... The orbit of the "dark star" that causes solar and lunar eclipses can also be calculated. Even if it does not exist at all, it conforms to the theory of nine numbers and exists in this model, just like the negative and imaginary numbers in calculations.

Moreover, with the premature appearance of the compass, this theory of Gai Tian also has its own correction: the earth is a circle, not a square, so even if you can circle around from west to east and then come back, it does not mean that the earth is a ball.

As long as the theory becomes a system, it can produce the calculation rules that conform to it, and the dark star that does not exist at all that causes solar and lunar eclipses can be calculated.

There were many debates at that time, and the Mohist school of Si Shang also raised many questions, which triggered a big discussion about the roundness of heaven and earth.

Fortunately, this theory has not been fully improved, and Si Shang seized a little and fought hard, and finally came up with two verifications that can prove that this theory is wrong.

One is whether you need to see the Big Dipper at the outer Heng. The outer Heng mentioned by Gai Tian is the Tropic of Cancer.

The other is to go to Zhongheng, that is, on the day of the Spring and Autumn Equinox, the sun is directly above the head to observe the starry sky in the north, and see if the distance between the stars has been reduced... If it is really made of the sky, the distance between the stars will gradually be closer with the naked eye to observe the naked eye.

This involves a question of "level hierarchy". The sun is the sun, so the height of the sun must be higher than that of the stars.

The debate left a deep impression on the gentleman, because he came forward to say something at that time and said it was a good thing. Because the model Gai Tian said can be self-consistent, at least now it can be self-consistent, and it is constantly corrected, which requires a lot of mathematical calculations. Regardless of whether the dark star that caused the lunar eclipse existed, the progress of nine numbers and geometry can be predicted.

Soon afterwards, the Mohist family on Si Shang began to advance into the South China Sea, replicating the strategy of Zhou Jianshang: Taibo ran to Wu and joined Xiqi to cut off the Shang Dynasty from east to west; Si Shang went straight to the South China Sea, intending to use the method of north-south to advance along the Pearl River and Xiangjiang River to complete the encirclement of Chu State.

Under the increasingly mature coastal navigation technology, some rumors brought about by Soluzan's return from the west also made many people moved.

Solusan heard of a city called Baktra in Persia. This city is the closest city to Persia, and the people there have communicated with India in the south. The Mohist activities in Shu Kingdom also received some news, and in the remote countries there, he also heard the rumors that there was a rich country in the West.

The development of industry and commerce brought about a desire for wealth. Land reform in the South China Sea area was also intended to expand the market, but the improvement from scratch was too slow. The rumors of those rich places prompted many people to hope to do business directly with the already developed places, thereby obtaining gold, silver and copper.

Just like treating Nanhai Fulou, productivity is bound by slavery and cannot be sold much. Only after land reform can the market be expanded and the industry and commerce will continue to flourish.

Nowadays, the trade on the road to the west has been captured by Qin. He has to go west and has no business to do with the barbarians. Only with the rich areas that have developed can you sell things.

Coupled with the debate about whether to gaze the sky or the earth, a year and a half ago, a sailing westward along the coastline from Yangyu.

One is to train navigation technology, this thing was originally built up by human life.

The second is a forced order promoted by the Mohist school of Si Shang. Under centralization, as long as you want to do it, there is nothing you can't do. At this time, the giant happened to know that there must be a place where a wealthy place can sell low-end beads, cotton cloths, and ironware at an excessive price.

The third is to have an object that can be traded. The trade volume of prosperous areas and Qianpi areas is completely different. However, the development of industry and commerce in Si Shang is very abnormal, and there are many things that exist in this era but are extremely expensive. According to estimates, if a broken glass bead is the first time to trade in the prosperous areas, it will always be exchanged for an equal amount of gold.

In some remote areas, even if you want to change gold, you can't change copper, so you can only change some animal skins. If you want to open up the market, you have to do it after Si Shang will lead the land reform and development and production. This is too slow.

In the end, it was also considered to verify that Gai Tian said it was wrong. When looking at the stars in a place like Zhendu, the spacing is still the same.

Even if Xi Liuzhou Master in Si has developed in recent years, he cannot be able to sail directly from the ocean. It is still possible to go to Japan from the southernmost point of North Korea, but no matter how far it is, it requires a lot of experience accumulation.

Relying on this newborn calf is not afraid of tigers, young people believe that verifying the will of heaven is a kind of fanaticism and a desire for wealth trade. A fleet of six sailboats that traveled west along the coastline left.

All you can rely on is the just-developed astronomy, where you can see the North Star, and relying on the compass won’t make mistakes.

Guitian, the youngest younger brother of the gentleman, was just finished studying from Xiliu Military Academy. Because of his excellent performance and the urge to petition, he became a member of the fleet sailing west a year and a half ago to find India.

In addition to silk, the cargo carried on the ship was all kinds of beads. Each ship could only hold thirty or forty people, half of which were young people who had just grown up and finished their school career.

The gentleman feels that those people are blown by the sea breeze and sunny all year round, and some people need to observe the height and angle of the sun all year round, and their eyes may be blinded by the sun, so they will naturally not look good. But she thinks that those people are very good, and they are all people who are as eager to achieve something that "benefits the world" like her.
