Both parties in the conversation know that in the long run, it is impossible to be with each other.

But at this time, no one mentioned the irreconcilable differences between the two sides, and were talking about harmony.

After roughly the negotiations, the caravan members returned to the inn.

Outside the inn, there were several soldiers sent by Linwu Jun to guard it.

The morals on Si caused tension among the princes. If you want to continue to move in some places, it is impossible to teach publicly like in the past, and promote morals such as equality, synonyms, love, selves, and labor to create wealth.

This is also a compromise. Especially after the alliance four years ago, the Mohist school never mentioned non-attack and stopped war, but kept saying that the world was the highest state of non-attack, and was always seeking to formulate war laws rather than international law similar to the Westphalian system to replace etiquette laws, and other issues such as the princes who have learned about their subsequent purpose.

It’s okay in some large cities in the Central Plains where management is relatively loose, but in Linwu, many actions are under surveillance and will be driven away if they are too out of order.

This is also a kind of self-protection for the vassal king. Trade gradually developed and was no longer a separate market centered on cities. But after gradually being connected by trade, they had to oppose the morality of the Mohist school, but they had to do business and could only be so compromised.

Such inns are more like designated trading places for sea bans rather than concessions, because the Mohist family cannot garrison troops here, and many activities are restricted.

However, there are several cities in Qi, where the Mo family strongholds are more like concessions, because Qi was defeated in the battle five years ago, and the Chu State has not yet failed and the Mo family was not ready to have a quarrel with Chu State before.

In the open space in the backyard of the inn, Shu Junzi and others were setting up the expensive and exquisite telescope to observe the stars rising in the night sky.

Several disciples are looking through the "Sui Xing Positioning Table" and calculate the longitude here based on the observed and calculated time difference between the orbit of Jupiter satellite and the local time.

No one has accurately measured the length of the meridian, but the so-called "40,000 Si Shangli" as mentioned by the two masters, instead of the saying that the day is shrinking by one inch and a thousand miles.

Whether it is Si Shang, Yue, Chu, or Qin, the operating position of the Sui Star satellite remains unchanged.

According to the table revised observations in Si Shang, by calculating the local time by observing the moon locally, the time difference between the two places can be calculated, thereby obtaining the approximate longitude.

The more carefully you observe, the more times you will see, the higher the accuracy of this longitude. It is not difficult to use the North Star to calculate the latitude.

During the Spring and Autumn Period and the Warring States Period, the astronomy of the Xia Dynasty had great progress. The earliest records of Jupiter moons such as "if there is a small red star attached to it" have also appeared, but it has gradually been lost in later generations. In addition, the relationship between destiny in heaven has made it impossible for non-Imperial Heavenly Supervisor to learn astronomy.

For example, the mysterious objects, astronomical books, prophecies, military books, seven stars, Taiyi, and Lei formulas are not allowed in private, and those who violate the rules will be punished for two years. Those who practice astronomy privately will be sentenced. Self-study astronomy will lead to the gradual observing of many astronomical observations that were found in the Warring States Period were gradually obscured.

…………

This time, there were many surveying and mapping teams for the Jiuzhou Mountains and Rivers map. The gentlemen entered Chu from the South China Sea, and several groups entered Chu from the rest of the direction.

Although the reason for saying it is that "The Mo family regards Yu as a saint, and Dayu faces wind and rain to measure the mountains and rivers of the nine provinces, so Mo has upheld the ambition of Dayu", it is still very difficult to obtain permission from the princes.

Because Dayu did something after testing Jiuzhou, he had to make the princes alert, that is, after testing Jiuzhou, he collected the troops from the world and forged the Nine Cauldrons.

This time, when the Mohist family wanted to measure the mountains and rivers of Jiuzhou, it was inevitable that the princes felt that this was not about learning from King Zhuang of Chu to compete for the importance of the throne, but about casting the nine throne by themselves.

Although the Mohist school repeatedly said that there was absolutely no such intention, the princes couldn't help but think more.

After Zhou destroyed Shang, he left a cauldron in Shangqiu, and there was a cauldron in Sanglin Society, and the rest were all in Zhoudu.

The tripod in the Sanglin Society is said to be later when the Song Dynasty was destroyed, and the people of Song Dynasty threw the tripod into Si Shui, but it was fashionable and existed. During the sacrifice, the Song Dynasty used the "Dance of the Sanglin" that required a large number of people.

Now that Song State is in chaos, many nobles are considering the "die" passed down from the Xia Dynasty in the Sanglin Society. If the Mo family had Song State, or controlled Song State, wouldn't it be the only one with a tripod besides the Zhou Emperor?

This time, it was even more meaningful to send people to measure mountains and rivers. It was just an excuse to be high-sounding, and it was worthy of the remaining power of the alliance four years ago, so it was difficult for the princes to refuse.

But the surveillance of these people was not relaxed.

Chu State Yangxia.

This is the first point to enter the surveying and mapping map of Chu from the direction of Song Dynasty in Pengcheng. Some people on Si have been surveying and mapping here for several days. The local county magistrates have always sent troops to follow him, called protection.

Outside the inn, dozens of Chu people wearing leather armor, carrying spears or carrying muskets, stood outside. Recently, Chu Mo's relationship was extremely tense due to the chaos in the Song Dynasty, and many Chu people did not dare to contact the Mo family again.

However, even if there are commands and guards, they cannot stop the thoughts of some people seeking knowledge.

Gan De, a native of Chu, wandered outside the inn, looking at the guards, and was still hesitating whether to go in.

Gande was an astrologer with his ancestral skills. His ancestors were astronomers of the Zhou Dynasty, or as people of the Category.

The so-called "after You and Li, the ministers and ministers do not remember the time of the rule, and the king does not report the new chapter. Therefore, the children of the Chou people were dispersed, either in the Xia or in the barbarians." This means that after the riots of the people, the Zhou Dynasty had declined, and the children of the Chou people were scattered in various countries.

Under the hierarchy, there is a very obvious characteristic that the son inherits the father's business, and different people have different identities and professions, which is destined at birth.

People in the Mo family are scholars, and are passed down from father to son, and sometimes they are used directly as their own surnames. For example, many people in the Mo family are like this, such as Gongfai and Zaimi.

Gan De's ancestors can be traced back to Gan Pan, a famous minister during the Wu Ding period of the Shang Dynasty. The Shang Dynasty attached importance to divination and was passed down from astrology. It is called the study of "Wu Xian". It is said that Wu Xian used divination and Wu Peng used to be a doctor. Gan De received a lot of astronomy education since he was a child.

Gande's ancestors were also proficient in divination and astrology. They even assisted Wu Ding in directors with a statement that God sent a dream to "God taught saints to the people" so that Wu Ding could avoid the opposition of the nobles and reuse Fu Ding.

It is precisely because he inherited the astronomy of the Shang Dynasty that in history, when he used the Star Classics to describe the Year Stars, he used more ancient Chinese literature from ancient times.

For example, ancient zodiac signs such as the Great Wilderness, the Red Fenruo are used less than the twelve earthly branches.

There are different opinions about the inheritance of this strange name. Some say that it originated from the exchange between the Xia tribes and ancient Babylon in ancient times. Shetieg is the ancient Babylonian transliteration of Virgo, so these strange names are found; some say that Shetieg is the clearness of the Xia in ancient times for different constellations, and Shetieg is the different names of three close constellations.

Gande himself didn't know the reason for this, because everything was too long. No one knew whether it was transliteration or ability or pronunciation of ancient languages.

The reason why Gande stood outside the inn today wanted to communicate with the inn inside was due to his observations of the starry sky over the years.

He observed with his naked eyes and summarized the retrograde cycle and general orbit of Mars and Venus; he saw with his naked eyes that there should be a moon-like satellite around Jupiter; he discovered that Jupiter's speed would feel fast and slow when observing on the earth; he drew the earliest star table...

These achievements are not just his own contribution, but should be regarded as a summary of the scholarship of people that his family has been passed down.

Before the Mohist school proposed the new cosmology theory, Gande had already vaguely opposed the Gai Tian theory.

When the big debate was underway four years ago, Gander's mother was seriously ill and he had to stay by his side to take care of him and did not participate.

However, he was considered to be the first among the scholars who recognized the astronomical theory of Si Shang, except for accepting the cosmic theory of Si Shang.

If the earth is round and moves around the sun, and Venus and Jupiter also move around the sun, then the retrograde trajectory of Mars and the various results of the changes in Jupiter's movement speed that he observed and summarized can have a more reasonable explanation.

Because Mars revolves around the sun and because Mars is closer to the sun, sometimes Mars will feel that it is retrograde when observing it, which is the simplest and most perfect explanation.

When he heard that the Mohist family saw the moon around Jupiter with a telescope, Gande could no longer sit still. He also observed the abnormal stars around Jupiter with his naked eyes, so he really wanted to take a look.

When Si Shang rose, he turned a blind eye to the outside world and kept looking at the stars at home, sorting out the astronomy passed down from his ancestors.

When Si Shang shocked the world and the Hundred Schools of Thoughts were controversial, his mother was seriously ill and he did not catch up.

Later, his mother died of illness and he was mourning at home. He began to read books on astronomy and mathematics on Si. He had a very good foundation in mathematics and astronomy, and he had some understanding in several years.

Now it is quite famous in the Yangxia area. Most of the local nobles interact with him. The State of Chu also invited him to serve as an official, but he refused before.

Since the decline of the Zhou royal family, the time when the accompanying ministers were in charge of the rule of law was not recorded, and all countries used their year names as the chronological unit.

It is okay to use it in this country, but when communicating with the vassal states, you must use the Year Star Anniversary Method.

Otherwise, Chu said that this was a certain year of King Chu. When communicating with Wei, the Wei people would have to convert that this was a certain year of King Wei.

The advantage of the year of the Year Star is that the whole world is the same. Jupiter reincarnates in a cycle of twelve years. Although it is not exactly twelve years, there will be a difference in about a hundred years, so it is not useful for the time being.
