Both sides of the conversation know that in the long run, it is impossible to and.

But at this time, they never mentioned the irreconcilable differences between the two sides, and they were talking about peace.

After the general discussion, the caravan returned to the inn.

Outside the inn, there were several soldiers sent by Lin Wujun to guard them.

Those morals in Sishang caused the tension of the princes, and in some places they wanted to continue their activities, and it was impossible to give public lectures as before, and trumpets such as equality, synonym, love, silverfish, and labor to create wealth.

It's a compromise. Especially after the alliance four years ago, the Mohists never mentioned the end of non-offensive warfare, but kept saying that the world is the highest state of non-aggression, and has been seeking to formulate the law of war instead of replacing the ritual law with international law similar to the Westphalian system, and so on, especially after the princes understood the purpose of the future.

In some of the more loosely managed cities of the Central Plains, it was fine, but in Linwu, many movements had to be monitored, and if they went too far, they would be driven away.

This is also a kind of self-protection of the feudal monarch, trade gradually developed, no longer a separate market centered on the city, but gradually began to be connected by trade, not only to oppose the morality of the Mo family, but also to not do business, can only be so compromised.

Such an inn was more like a designated trading place for the opening of the sea ban than a concession, because the Mo family could not garrison troops here, and many activities were quite restricted.

On the Qi side, there are several Mo strongholds in the cities that are more like concessions, because the Qi State was defeated in the First World War five years ago, and the Chu State has not yet failed, and the Mo family was not ready to fight with the Chu State before.

In the open space in the backyard of the inn, the gentleman and the others were setting up their expensive and delicate telescopes to observe the stars rising in the night sky.

Several disciples were looking at the "Star Positioning Table", calculating the longitude here based on the observed and calculated orbital time of Jupiter's moons and the time difference of local time.

The length of the meridian has not been accurately measured, but the theory of 40,000 Si Shangli as stated by the so-called two masters is adopted, rather than the saying that the day shrinks by an inch and a thousand miles.

Whether it is in Sishang, Yue, Chu or Qin, the operating position of the Suixing satellite is unchanged.

According to the revised observation table in Sishang, the time difference between the two places can be calculated by observing the moon locally, and the approximate longitude can be obtained.

The more carefully and often you observe, the more accurate this longitude will be. Latitude can be measured using the North Star, which is not difficult.

During the Spring and Autumn Period and the Warring States Period, the astronomy of Zhuxia had made great progress, including the earliest records of Jupiter's moons such as "if there is a small red star attached to its side", but it was gradually lost in later generations, and the relationship between the Mandate of Heaven made it impossible for non-Qin Tianjian to study astronomy.

Such as all the occult artifacts, astronomical books, prophecy books, military books, Qiyao calendars, Taiyi, and thunder formulas, private people are not allowed to have them, and those who violate them will be imprisoned for two years. The same applies to those who study astronomy privately. Self-study of astronomy was punishable, which also led to the gradual obliteration of many astronomical observations that existed during the Warring States period.

…………

This time, Sishang sent people out to carry out a map of the mountains and rivers of Kyushu, and there were many teams that entered Chu from the South China Sea, while several teams entered Chu from the rest of the directions.

Although the reason is that "the Mo family takes Yu as holy, and Yu measures the mountains and rivers of Kyushu in the wind and rain, so the Mo people hold the ambition of Yu", but in fact it is still very difficult to get the permission of the princes.

Because Dayu did one more thing after measuring Kyushu, this matter had to make the princes vigilant, that is, after measuring Kyushu, he collected the world's soldiers and cast Jiuding.

The Mo family wants to measure the mountains and rivers of Kyushu this time, which inevitably makes the princes feel that this is not to learn the importance of King Chuzhuang's victory, but to cast Jiuding by themselves.

Although the Mo family repeatedly said that there was absolutely no such meaning, the princes couldn't help but think about it.

After Zhou destroyed the Shang that year, one tripod was left in Shangqiu, and there was another tripod in the mulberry forest society, and the rest were in Zhoudu.

It is said that when the Song Kingdom collapsed, the Song people put the Ding into Surabaya, but this fashion and existence, and when the Song Kingdom was strong, it also used the "Mulberry Forest Dance" that required a large number of people.

Now that the Song Kingdom is in turmoil, many nobles are considering the "Ding" handed down from the Xia Dynasty in the Sanglin Society. If the Mo family won the Song Kingdom, or controlled the Song Kingdom, wouldn't it be the only one in the Mo family other than Zhou Tianzi who had a ding?

This time, he directly sent people to measure the mountains and rivers, which was even more of a bit of a statement, but it was just an excuse to be high-sounding, and it was worth the prestige of the great victory of the Huimeng four years ago, and the princes could not refuse.

But there is no relaxation in the surveillance of these people.

Chu Guoyang Xia.

This is the first point to enter the surveying and mapping map of Chu from the direction of Pengcheng Song State, some people in Sishang have been surveying and mapping here for several days, and the local county magistrate has always sent troops to follow, called protection.

Outside the inn, dozens of Chu soldiers wearing leather armor and holding spears or carrying muskets stood outside, and recently the relationship between Chu and Mo was extremely tense because of the civil strife in the Song Dynasty, and many Chu people did not dare to contact the people of the Mo family again.

However, even if there are orders, even if there are guards, they can't stop the minds of some people who seek knowledge.

Chu Gander wandered outside the inn, looking at the guards and still hesitating whether to go in.

Gander was an astrologer, an ancestral craft, and his ancestors were astronomical officials of the Zhou Dynasty, or they were called domain people.

The so-called "after the seclusion and the power, the history of the courtiers is not recorded, and the king does not tell the time, so the children of the people are scattered, or in Zhuxia, or into Yidi", that is, after the rebellion of the people, the Zhou Dynasty has declined, and the children of the people are scattered in various countries.

Under the hierarchy, there is an obvious feature that the son inherits the father's business, and different people have different identities and occupations, which are destined by birth.

They are scholars, passed down from father to son, and sometimes even directly used as their own surnames, such as many people in the Mo family, such as public creation, contempt and other surnames.

The ancestors of Gander can be traced back to the Shang Dynasty Wuding when the famous minister Ganpan, the Shang Dynasty attached great importance to divination, astrology has been passed down, known as "Wu Xian" of learning, legend Wu Xian is a Zheng, Wu Peng is a doctor, Gander has received a lot of astronomical education since childhood.

Gander's ancestors were also proficient in divination and astrology, and even assisted Wu Ding in directing a play in which "God bestows saints on the people" so that Wu Ding can avoid the opposition of the nobles and reuse Fu Shuo.

It is precisely because he is in the line of Yin Shang astronomy that he used some ancient texts in history when he used the year and star chronology to make the star classics.

For example, the names of ancient constellations such as Setig, Great Wilderness, and Chifenruo are rarely used to support the twelve.

There are different theories about the inheritance of this strange name, some say that it originated from the exchange between the Zhuxia tribe and ancient Babylon in ancient times, and Setig is the ancient Babylonian transliteration of Virgo, so there are these strange names; It is also said that Setig is the Ming of the different constellations of Zhuxia in ancient times, and Setig is the different name of the three constellations that are close to each other.

Gander himself did not know the reason for this, because everything was too old, whether it was transliteration or the pronunciation of ancient languages, and no one knew about the evolution of thousands of years.

The reason why Gander stands outside the inn today and wants to have some communication with the ink inside, stems from his observation of the starry sky over the years.

He observed and summarized the retrograde period and approximate orbit of Venus on Mars with the naked eye; He saw with the naked eye that there should be a moon-like moon around Jupiter; He discovered that Jupiter's orbit felt fast and slow when observed on Earth; He drew the earliest star catalogs......

These achievements are not just his own credit, they should be counted as a summary of the knowledge of the people that his family has always passed down.

Before the Mohists proposed a new cosmological theory, Gander had already vaguely opposed the Gaitian theory.

When the debate was going on four years ago, Gander's mother was so ill that he had to stay by his side and not attend.

However, he can be regarded as the first person to approve the theory of astronomy in Sishang among the scholars who inherited the ancient astronomy, in addition to accepting the cosmological system of Sishang.

If the earth is round and moves around the sun, and Venus and Jupiter also move around the sun, then the results of the retrograde trajectory of Mars and the changes in Jupiter's orbit that he observed and summarized can be explained more reasonably.

Because Mars revolves around the Sun, because Mars is closer to the Sun, it ...... Mars sometimes feels like it's retrograde, which is the simplest and most perfect explanation.

By the time he heard that the Mojia telescope had seen the moon around Jupiter, Gander couldn't sit still, and he also observed the anomalous stars around Jupiter with the naked eye, so he really wanted to take a look.

When Sishang rose, he didn't listen to anything outside the window, and he was always looking at the stars at home, sorting out the astronomy passed down from his ancestors.

When Sishang shocked the world and hundreds of schools of thought were arguing and debating, his mother was seriously ill, and he didn't catch up.

After his mother died of illness, he began to read books on astronomy and mathematics in Sishang, and his foundation in mathematics and astronomy was excellent, and he understood it in a few years.

Now he is quite famous in the Yangxia region, and the local nobles often associate with him, and the Chu State has also invited him to come out, but he has refused before.

Since the decline of the Zhou royal family, the ruling history of the courtiers is not recorded, so that all countries use their own era names as the chronological units.

It's okay to use it domestically, but when you communicate with the vassal states, you have to use the chronology method.

Otherwise, the state of Chu said that this was the year of the king of Chu, and when communicating with the state of Wei, the Wei people had to convert this to the year of the Marquis of Wei.

The advantage of the year is that the whole world is the same, Jupiter has a cycle of 12 years, although because it is not exactly 12 years, there will be a difference in about 100 years, and it is not needed for the time being.

Therefore, people like Gander, especially those who are proficient in the chronology of the stars, need to be used by the vassal states to control the astronomy of the calendar, observe the celestial phenomena by the way, and make some divination or predictions.
