He understood that his status and official position were closely related to the trade of the Mo family, and the annual border tax provided a large amount of income for the king of Chu, and it was also part of the source of military spending for the new army of Chu.

When I heard the news that more than half of Lechang Gorge was being built, I was happy, and I thought that I would have to deal with more people in the future, so I reminded two sentences.

Another is also because of the batch of arms that Lin Wujun bought, he doesn't know the Tao inside, and there is no problem with normal reporting, but the prince Liangfu patrols the border on behalf of the king, and Lin Wujun is also in the city, so it is best to have a reminder.

If it's a normal transaction, it's easy to say; If it's some secret dealings, it's good to be careful.

Although he didn't know that there was a turmoil in the Chu State now, he could probably feel it.

The leader of the caravan hurriedly thanked him, paid the full amount of customs duties according to the number of goods on the list, and obtained the stamp sheet, and told the caravan to move forward quickly, and strive to arrive at Linwu tomorrow morning.

In the cars at the back of the convoy, a gentleman who had graduated for a year was talking to several "disciples" about measurement in the car.

She is young and a woman, but she is called sir, and she is still a little unaccustomed.

After completing the study, he took some people who were not admitted to the order, but the level was not bad to start the measurement work, this time to draw a map of Kyushu, Sishang spent a lot of effort, out of a lot of people.

After nearly two years of observation and recording, the knowledge of using the Tai Sui Star satellite as a timer to measure longitude and draw an accurate map has been enough to implement, so she has brought her disciples to Linwuguan today.

At this time, after talking for a while, when everyone was tired, a female disciple couldn't help but think of a lace news she heard, and said with a grin: "Sir, have you heard, the prince of Chu is a good man, he likes men the most, it is said that the wife around him is to give birth to a son, and the people next to him are all beautiful young men." ”

Just now I heard Linwu Siguan talking about Wang Liangfu patrolling the border on behalf of the king, and this female disciple's mind was full of pictures of those two beautiful men together.

The gentleman said with a smile: "The nobles of the Chu State are so manly, and it is not something that only happens now. Why, do you like this? ”

The female disciple covered her mouth and smiled: "I don't like this kind of thing, I just want us to go to Linwu, but I can see the beautiful young men around Wang Ziliangfu, and see if they are really so good-looking." ”

The gentleman said disdainfully: "Those who make money will be cut off when their wealth is exhausted; Those who make friends with Israel love Chongqing. Born good-looking but can only rely on the bed to obtain the master's favor, even if such a person is born good-looking, I don't want to take a second look. ”

"But you are women, like me, and you must learn more, which will be useful. Even if jade is hidden in the stone, it is also jade. ”

Those female disciples hurriedly said yes, but they thought in their hearts, I am not ugly, and besides, if I look for a good husband, I will not look for a male pet for the princes and nobles, just look at the skin.

How did they know that the words of the gentleman were not only educating them, but also thinking about their little brother returning to the field.

When she returned from Zhao Di four years ago, she was just in time for the great debate of the hundred schools, and the fate of her little brother could be regarded as changing because of this debate.

Since she was a child, she has been teaching the theory that the earth under her feet is round, and now her measurement work is based on that theory, so she is naturally interested in that controversy.

At that time, those who supported the Gaitian theory proposed a perfect model called it Seven Heng and Six Rooms.

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

Moreover, the sun is like a lamp and candle, and it cannot be seen when it is far away, so it is possible to calculate the height of the sun by saying that the sun shadow is one inch, and the sun is far away because it is dark.

On the day of the summer solstice, the sun moves on the inner balance, because the radius of the inner balance is very small, so the extreme north can be cautious to the north, and it is completely possible to have a situation where the sky is not dark all day.

When the sun is in the outer balance, then the extreme north will naturally be forever nightless, because the distance of the sun in the outer balance is too far to be seen.

As for the solar and lunar eclipses, it is because there is a dark star in the sky, and this dark star orbits in the sky, but the altitude is lower than that of the sun and the moon, so there are solar and lunar eclipses.

The controversy over this model of heaven and earth is not only an academic controversy, but also an extremely serious political controversy.

The sky is round and the earth is round, the heavens and the earth are on the ground, and under this model, the hierarchy is also implicitly in the way of heaven and earth, and the heavens are respected and the earth is humble, so the Son of Heaven can rule Kyushu.

However, if the earth is round, and the circle is equal everywhere, and the upper and lower are just a relative concept, the legitimacy of the Son of Heaven has been greatly impacted.

The weirdness 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 the solar and lunar eclipse can also be calculated, even if it does not exist at all, but in this model it conforms to the science of nine numbers and exists, just like the negative and imaginary numbers in the calculation.

And with the premature appearance of the compass, this theory of covering the sky has its own correction: the earth is a circle, not a square, so even if it can go around from west to east and back again, it does not mean that the earth is a ball.

As long as the doctrine becomes a system, then it can be calculated that it conforms to the laws of calculation, and the dark stars that cause solar and lunar eclipses can be calculated if they do not exist at all.

At that time, there were also many controversies, and the Sishang Mojia also raised many questions, which triggered a great discussion about the circle of heaven and earth.

Fortunately, this doctrine has not yet been completely perfected, and Si Shang's side seized a little bit and chased hard, and finally came up with two verifications that could prove the error of this doctrine.

One is to need to be at the outer balance, whether you can see the Big Dipper, and the outer balance that Gai Tian said is the Tropic of Capricorn.

The other is to go to Zhongheng, that is, on the day of the spring and autumn equinox, where the sun is overhead, to observe the starry sky in the north and see if the distance between the stars has been reduced...... If it is indeed a sky-covering, then the distance between the stars will gradually decrease as the naked eye looks southward.

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

The controversy left a deep impression on the gentleman, because at that time he came forward to say something that was a good thing. Because the model of the Gaitian theory can be self-justifying, at least for now, and is constantly being corrected, it requires a lot of mathematical calculations, regardless of whether the dark star that causes the lunar eclipse is or not, the progress of nine numbers and geometry is predictable.

Soon after, the Sishang Mojia began to advance into the South China Sea, copying the strategy of the Zhou Shang Dynasty: Taibo ran to Wu and fought with Xiqi to cut off the Shang Dynasty; Sishang went straight to the South China Sea, intending to use the north-south approach to complete the encirclement of Chu along the longitudinal line of the Pearl River and the Xiangjiang River.

With the maturing technology of coastal navigation, some rumors brought by Solushen's return from his westward journey also made many people excited.

Solushen had heard of a city in Persia called Bhaktra, which was the closest city to Persia in the Central Plains, and the people there had some communication with India in the south; The Mo family's activities in Shu also got some news, and the remote country over there also heard rumors that there was a rich country in the west.

The development of industry and commerce brought with it a thirst for wealth, and the land reform in the South China Sea was also aimed at expanding the market, but the improvement from scratch was too slow, and rumors of those rich lands prompted many people to want to be able to do business directly with the areas that had already developed, so as to obtain gold, silver, and copper.

Just like the South China Sea Bondage, the productive forces were tied down by slavery, and they could not sell much at all, and only after the land reform could they expand the market and continue to promote the prosperity of industry and commerce.

Now the trade on the westward road is in the hands of the Qin State, and it is impossible to go west without the Qin State, and there is no business to do with the barbarians, and it is only possible to sell things with the rich areas that have developed.

This, combined with the debate over whether to cover the sky or the earth, prompted a voyage west along the coastline from Yangyu a year and a half ago.

One is to train sailing skills, which were originally piled up by human life.

The second is the compulsory order promoted by the Sishang Mojia, under the centralization, as long as you want to do it, there is nothing that cannot be done, and at this time, the giant happens to know that there must be a rich place where you can sell low-end Xuanlin beads, cotton cloth, and ironware at excess prices.

The third is to have an object that can be traded, and the trade volume of the rich and developed areas is completely different from that of the poor areas. However, the industrial and commercial development of Sishang is very deformed, and there are many things that exist in this era but are extremely expensive, according to estimates, if a broken glass bead goes to a rich area for the first time, it can always be exchanged for the same amount of gold.

In some remote areas, even if you want to exchange gold and copper, you can't change it, you can only change some animal skins, and if you want to open up the market, you have to be led by Sishang to carry out land reform and development and production, which is too slow.

In the end, it is also to verify that Gaitian is wrong, and looking at the stars in a place like body poison, the spacing is still the same.

In recent years, even if the Xiliu Boat Master has developed, it is not directly possible to sail in the ocean, and it is still possible to go to Japan from the southernmost tip of Korea, but no matter how far it is, it requires a lot of experience accumulation.

With the frenzy of devotion to the devotion of the newborn calf, the devotion of the young man to test the will of heaven, and the thirst for the trade in wealth, a fleet of six sailing ships sailed west along the coastline.

The only thing we can rely on is the newly developed astronomy, which is always where you can see the North Star, and you can't go wrong by relying on the compass.

The youngest brother of the gentleman, Guitian, had just graduated from the Xiliu Military Academy, and because of his excellent performance and the urge to take the initiative to petition, he became a member of the fleet that had sailed west in search of India a year and a half earlier.

In addition to silk, the goods carried on the ships were all kinds of Xuan Lin beads, and each ship could only hold thirty or forty people, half of whom were young people who had just grown up and just finished their school careers.

Shu Junzi thinks that those people are blown by the sea breeze and the sun all year round, and some people who need to observe the height and angle of the sun all year round may be blinded by the sun, and naturally they will not be good-looking. But she thinks those people are very good, they are all people who are as eager as her to achieve something "good for the world".

Just like this time when he came to Chu to survey and map the country, Shu Junzi felt that this is the unity of benefiting himself and benefiting the world, he likes this industry and likes his own work, and this kind of work can make the world beneficial, and she feels that she has achieved the "equal division of their duties, each of them is happy" as said in the "Datong".
