Zhuge Liang parted ways around September 20th, and he wandered leisurely on the road for a few days. He returned to Chang'an on September 25th, and then he began to contemplate the calculations and write about the rules of the star map.

As for Li Su, it will take about twenty days to return to Chengdu after starting from Chen Cang and heading south. It is basically half past October, and there is nothing to say in these twenty days. Even if you return to Chengdu, you will definitely have to rush to comfort your wife who is about to give birth and have nothing else to do.

Let's take your eyes back to Zhuge Liang's side.

Zhuge Liang obviously learned from Li Su that he had the talent of "knowing this matter must be practiced", so he did not only rely on calculating his writings. In the past few days, he also took the records of "Zhang Henghunxiang" in the Chang'an Palace, and then studied them in detail and renovated his own things. He tried to prove the "period law of the emergence of the Heart of the Heart", and some other planetary movement rules as testimony as circumstance testimony to completely refute the theory of astrological disasters and strangeness.

(Note: The "armillary celestial sphere" recorded in middle school history books include the ambulance and the ambulance sphere. The former is the celestial sphere, and the latter is an observer with a spy tube, which is equivalent to a fixed angle telescope without lenses. Zhuge Liang only needs to learn from the ambulance sphere here, and does not need to use the ambulance sphere, because he only calculates and does not observe)

Zhang Heng was the Grand Historian during the reign of Emperor Shun of Han. It was more than 60 years ago. At that time, the capital of the court was still in Luoyang, so there must be no real thing in Zhang Heng's mosaic of Chang'an.

When Dong Zhuo was burning Luoyang forcibly moving, he would not move heavy and precise bronze ware, so Zhang Heng's moist elephant had long been melted into copper coins.

Fortunately, all the written materials left by Zhang Heng when he was the Grand Historian were stolen by Cai Yong five years ago in Jiangzhou. After Liu Bei recovered Chang'an, he transported them back in batches. It has not been transported yet, because the conditions in Chang'an are not good, and the palaces and cities have not been completely restored. Cai Yong just transported the copies that had been copied over the years, and the ones that were not copied by the lonely book will not be transported.

Zhuge Liang went to Cai Yong to find information, copied the ecliptic abyss and the five planets of the old elephant, and then adjusted according to the "heliocentric theory" taught by Li Su.

Not to mention that after Zhang Heng developed into the "Huantian Theory", it was actually quite similar to the Western Ptolemy's "earth-center theory". The main difference is that Zhang Heng did not think that the earth was a ball, but felt that the upper half of the celestial sphere was air and the lower half was water, and the earth floated in the water in the center of the hemisphere.

Therefore, Zhang Heng's theory does not prevent the Eastern people from looking at the sky, but their understanding of the earth is a little worse than that of the West. To accept the heliocentric theory, one must overcome a cognitive obstacle to gravity. However, for Zhuge Liang, who has already accepted the setting of "gravity", it is not bad.

In fact, gravity was not discovered by Newton in history. After all, as early as a few hundred years before Newton, humans realized that the earth must be round and sailed around the world. Then gravity must be recognized.

However, people at that time did not know that gravity was "all-round", and only thought it was a unique characteristic of the earth, and even believed that gravity was a magnetic force, so they did not give a formula inverse thrust constant.

Therefore, with the knowledge of people about the 12th century, it is not as difficult as imagined to be able to recognize gravity qualitatively.

After Zhuge Liang finished calculating, he felt that it was not intuitive enough, or he wanted to verify it. He had a flash of inspiration and thought of adding "tooth chain transmission" to his adjusted zodiac surface five-star motility to ensure that "the earth goes one frame a day", gold, wood, water, fire, and Saturn also goes one frame.

In this way, Zhuge Liang inserted 365 toothpicks into the Earth's orbit on the zodiac plate, making it like a coiled machine gun chain, except that the bullet is inserted on it but a toothpick, which serves as the limit convex contact for the transmission of the tooth chain.

Then next to the base of Hunxiang, make a shaking handle. The handle is also rotated with a belt knot rope with a toothpick wheel. A toothpick corresponds to a knot.

There is nothing much to say about this. Zhuge Liang was no longer familiar with the tooth chain transmission mechanism when he was working on a water truck transmission mechanism. He started dealing with these things three years ago, which was clearer than Li Su. Now that he became a spiritual commander, he can only be considered a return to his old career.

Zhuge Liang inserted 687 and toothpicks on Mars' zodiac plate according to the Mars orbital cycle, which corresponds to the 687 days of Earth in a circle of Mars.

For other Venus and Mercury's orbital cycles, Zhuge Liang also divided the Mercury ecliptic disc in the innermost circle into 88 grids and Venus 225 grids according to Li Subao's answer - these two things can be used as circumstance evidence to verify the correctness of his model.

Originally, Zhuge Liang wanted to add Saturn and Jupiter, but Jupiter had more than 4,300 days on Earth in one circle and more than 10,700 days on Earth. He found that the amount of model projects was too large and he gave up temporarily.

If the court is willing to send him craftsmen, pay for money and have plenty of time in the future, he doesn't mind making a Saturn Zodiac Wheel with more than 10,700 teeth to simulate. Anyway, the production has no technical content, so he is only responsible for giving data, and the craftsmen's physical work is followed.

After the work was done, Zhuge Liang personally shook the handle of the steering wheel to make the water, gold, earth and fire turn at the same speed.

After the experiment, he found another problem - according to the reason Li Su said, Mars had stagnation because the orbit was not a circular but an ellipse. Zhuge Liang initially let the Martian zodiac wheel rotate directly, so the wheel made was a perfect circle, so it would not be used.

After thinking about it, Zhuge Liang divided each zodiac wheel into two parts - the inside is an oval fixed wooden wheel, without turning, the outside is the belt knotted wheel mounted on the wooden wheel, and the "toothpick chain" is also inserted on the belt knotted rope. When shaking the handle to pull the pulley, let the belt rub and slide directly on the wooden wheel.

In order to reduce friction, Zhuge Liang also applied oil to the belt to ensure that the belt tensioned on the oval wooden wheel will not be dragged.

The whole work took him more than ten days to construct (not his own construction, but he had money anyway, so he spent a lot of money to hire a lot of carpenters and cobblers). The moment he finished it, he felt quite accomplished.

"Let's try to turn again. Well, people should always stand facing the earth and observe at the angle of the celestial sphere. Once the three points and one line, the third point is projected on the heart on the celestial sphere. And when the stagnation of the day is stagnation, record the time. Then continue to turn, watch the next time to the stagnation of the day, record the time, and watch the heart again after a few rounds."

Zhuge Liang thought to himself and calculated the test method, and then began to roulette the wheel handle. His wheel handle was coaxial with the Earth's zodiac wheel, and it would be equivalent to 365 days if he turned around, so it was easy to keep accounts.

Soon, Zhuge Liang's expression became very exciting because he found that his experimental instrument basically matched the theoretical algorithm mentioned by Master Li.

On average, every fifteen or sixteen years (circle), an approximate Yinghuo guards the heart will appear, but it may not be facing Xinsu 2, with a slight error.

More importantly, Zhuge Liang recorded the current position of Mars, Venus, Mercury, and after setting it to its initial state, he continued to shake the wheel. The previous and subsequent astrological records are consistent with this year's observation results - in this way, even for outsiders, it can prove that the orbit itself is correct.

With this set of experimental instruments, he would not have to talk nonsense with other officials in the Taishi Ling system and do technical debates, and could directly demonstrate it to laymen. Ladies who don’t even know at all can at least understand the simulation results to know right or wrong, which can directly let laymen in power make decisions and arbitration.

Just like for a poor student, watching the demonstration video directly is not much easier to understand than watching formula debate calculation process?

...

Zhuge Liang was still complacent, not knowing that his "unemployed" and "delayed in recording observation results" and other non-ancient behaviors were recorded by his colleagues.

There are also some officials who have been living in the Taishi circle left over from the Li Jue era, who are also dissatisfied with his behavior of directly turning over the table and destroying all the jobs of the Taishi officials who are not in the history.

After all, if Zhuge Liang's plan was accomplished, no one else had learned it. It turned out that he had accumulated many years of work experience and could not continue to use it. He was denounced as a heresy, so why wouldn't all be laid off?

Fortunately, Zhuge Liang was in a tough backstage, and the Grand Historians knew that Zhuge Liang was the right general, and did not dare to move lightly. So they just wrote down Zhuge Liang's deviant behavior in their small notebook first, and would not take it out for the time being, waiting for the right opportunity.

However, this opportunity came soon - it turned out that some foreign princes also had genius staff members, and observed the extremely fierce "Yinghuo Shuxin" this September.

So, Zhuge Liang himself did not realize that he would soon be pushed to the forefront and fight against the doubters and disaster factions.

This kind of thing will be bizarre to later generations think of it, but it was a complete basic operation at that time. As we all know, in the era of heaven and man, Ying Huo Shuxin was a weapon for the opposition to attack those in power, forcing the rulings to commit suicide and give up important positions, especially in the Han Dynasty, which was harmed by Dong Zhongshu, which was so easy to use.

Now the emperor is reluctant to die and is not hostage by the thief ministers. Those princes who are in the heart of the world, who have not found an excuse to fight and expand their territory after pacifying their internal Yellow Turban thieves, have long been impatient. Of course, they also have to seize this opportunity to condemn the emperor, at least to condemn the emperor's close ministers.

So, the one who jumped out this time was Yuan Shu.

...

It turned out that as early as more than ten days ago, just in mid-September, some of the advisers and celebrities from Yingchuan and Nanyang County under Yuan Shu had observed this abnormal celestial phenomenon.

There are still many talents in Nanyang and Yingchuan. The Yingchuan faction likes to spread the most remarks such as "Stars gather in Yingdi, and there will be many wise men in the place", and has formed gangs and ranks for their own party to build momentum.

The talents in Nanyang County are mainly Sima Hui, Huang Chengyan, and Pang Degong. After several years of history, these people gathered under Liu Biao's command due to the defeat of Yuan Shu. At that time, Liu Biao's power in Xiangyang County expanded to the north bank of the Han River, including Xinye and Deng County.

But in this time and space, Nanyang County is still under Yuan Shu's hands, and not Zhang Xiu, who was controlled by Liu Biao, who was remotely controlled by Liu Biao. Therefore, Liu Biao's Xiangyang County is not large in area, and famous scholars from the north of Han Dynasty, such as Sima Hui and Huang Chengyan, still lived in Yuan Shu's jurisdiction.

At that time, Yan Xiang, under Yuan Shu, was the first to discover "Ying Huo Shuxin", and then reported it to Yuan Shu, and advised him to take the opportunity to attack the imperial center - not to target the emperor, but to target Dong Cheng, and to describe this super fierce sign as "Dong Cheng blocked the king's road and was inappropriate."

Yuan Shu was overjoyed when he heard this and immediately asked Yan Xiang to submit, posing as "clearing the emperor's side and rectifying the celestial phenomena."

Unfortunately, Yan Xiang's professionalism is a bit awkward. He just noticed that Mars stopped in Xinsu Er for a while, but he didn't understand the more detailed professional interpretation.

Yuan Shu gave him this task, of course he had to make complete preparations and make solid theoretical efforts before he could set out. Yan Xiang could fully imagine that after he went to Hongnong, he would be refuted by the central officials such as Taishi Ling Taicheng, so he had to prepare a professional and excellent astronomical troll to stop.

Yan Xiang was the first to think of Sima Hui, so he prepared a gift as early as September 12th, and went to Sima Hui's hometown, Yangdi County, Yingchuan County, and solemnly came to ask Sima Hui to accompany him on a business trip.

Yan Xiang's attitude of visiting was kind: "Yan Xiang, the chief clerk of the General Wei, has seen Mr. Shui Jing. I have long heard that Mr. Shui Jing is good at astronomy and geography, and he is inclusive of everything. Recently, I have observed the celestial phenomena at night and saw that the September 1999 is in a sign of being extremely evil. What does the teacher think? General Xiang Mengwei sent him to Beijing soon to make a statement, advise Your Majesty to open up the road of speech, rectify those close ministers who blocked the king's road and did not match the position, and use clear politics to appease the distance and the nearest. However, Xiang's wisdom and wisdom are short and have limited knowledge of the law of heaven. Please help me."

Sima Hui sued the crime with a cane: "I am nearly fifty years old and do not care about the government affairs. I can only watch the stars at night but only entertain myself. Master Yan asked me wrongly."

Yan Xiang's face changed and he wanted to say a few threatening words such as "Is the sword of General Your TV Guard unfavorable?" After enduring it for a long time, he finally got back. He also wanted to give some face to a famous scholar like Sima Hui.

Sima Hui had extensive experience, so how could he not see Yan Xiang's murderous intent? He also had to give Yan Xiang a step, so he took a step back and said with grudges: "Do you think Yan Zhuan doesn't believe it? I am indeed not conducive to doing this. I recommend a friend. This is not the skill of this person, but he is enthusiastic about entering the world, which is not like me evading the world. I wrote a letter and handed it to Yan Zhuan to invite him, and I can get it."

Seeing that Sima Hui was still working together, Yan Xiang was just "a dead fellow Taoist who died but not a dead Taoist", so he took the opportunity to go down: "I hope to hear the details."

"This person is Huang Chengyan, a famous scholar in Nanyang..." Sima Hui said, and sold his teammate's information.

Yan Xiang let Sima Hui go and went back to find Huang Chengyan. It took a few more days to get together with Hongnong's team for advice.

Huang Chengyan is no more than a hermit like Sima Hui. He has a family that needs to be protected and cannot afford to offend Yuan Shu, so he pinched his nose.

Although he also realized that Yuan Shu would definitely not do good things, it was not his Huang Chengyan's management. He was only responsible for interpreting the astrological signs and citing classics to prove that this was indeed a very cruel thing for the court. As for how to persuade the emperor to rectify and carry private goods, it was Yan Xiang's problem.

Yuan Shu's delegation set out from Nanyang around September 20th, and left for seven or eight days. He left Guanguan to Lantian County controlled by Qiao Rui. Qiao Rui heard that the lord's chief clerk Yan Xiang was coming, so he was polite to receive and serve him carefully. Yan Xiang also took the opportunity to ask Qiao Rui about Guanzhong and Hongnong, mainly because he was afraid that there would be experts around the emperor.

Yan Xiang asked, "Has the right general Li Su been on a promise recently? As the Jingzhao Yin, he was a trouble. When the late emperor was still alive, he praised Li Su repeatedly for knowing the will of heaven, and now he respects his theory more and more. This person has always refuted the theory of heaven and man's response to disasters and strangeness. If we encounter Li Su's rebuttal, even if I brought Huang Chengyan and his disciples, I would not be able to argue with Li Su in front of the imperial court, so I had to listen to the will of heaven and man to do my best."

However, Qiao Rui's answer made Yan Xiang very happy: "Master Yan, you are lucky! You don't know yet? Li Su was called as the governor of Yizhou by the King of Hanzhong. He had already taken office more than ten days ago. Now he probably has gone to Hanzhong County."

Yan Xiang was overjoyed: "What? That's really God helping the lord! Li Su is gone, Jingzhao, the land of Hongnong. Regarding the knowledge of the destiny of heaven, who can argue with me and Huang Chengyan's combination, let alone the celestial phenomena itself help me!"

Qiao Rui thought for a while and added: "However, before Li Su left, I heard that he used the quota for the quota of Maocai this year, and used public service to support one of his disciples, named Zhuge Liang, who was 15 years old and was divided into the power of the Grand Historian. I wonder if it will affect the major affairs of the chief clerk?"
