Chapter 668 Missing

"That's the spirit I see in you."

"This spirit is the treasure of Si Tianjian, so you can't leave, you should calmly accept the title of the first bachelor of Huangsong University of Technology, so as to inspire future successors to follow your footsteps and continue to explore!"

"Since the beginning of China, countless learnings have been lost, the Han and Tang dynasties have been continuous, and no one can understand the ancestor's "Fixation", this kind of thing cannot be allowed to continue in our hands."

"So I thought of some ways to change the way we record this science, so that it no longer has the difficulty of being inaccessible and having to be taught orally in order to comprehend."

"This is the basis for promoting our knowledge, so as to attract more colleagues to contribute to this knowledge."

But these are trivial matters to you, and there are no constraints. Because your knowledge doesn't need these things, you have gone ahead of us, to heights that are difficult for us to reach. ”

"What we want to do is to translate your knowledge into something that everyone can understand and study. So Wei Gong, you don't have any burden, just those boys, you should be treated as an ancestor! ”

"You can count them with your eyes closed, can they still be reasonable?! Did someone say something weird? I'm going to check it out, I can't clean him up! ”

Wei Pu Lao burst into tears: "No, no, Fengyuan Calendar, Lao Er thought it was perfect, and the prison judge and Zhang Tianshi introduced the precession so that it could be adjusted year by year, this method was already above Lao Er, and it also solved Lao Er's confusion for many years." Your knowledge is higher than that of Lao Er, and Lao Er is ashamed and does not dare to take the post. ”

"Fengyuan Calendar", with the beginning of spring as the New Year's Day, the year is set at 365 days, the 31st day of the big month, the 30th day of the small month, the 24 solar terms are arranged at the end of the first half of the month, the beginning of the second month, in fact, it is quite similar to the calendar of later generations, and it is also the most advanced calendar today.

However, Su You and Zhang Tianshi made a move, making this method more advanced, and refined the two systems of the sun and the Taiyin, to return to the year to determine the year, to the lunar calendar to determine the month and day, although it is complicated, but in the 24 solar terms, with the yellow longitude declination as the degree, with the sun along the ecliptic from south to north through the equator of the focus of the vernal equinox, the yellow longitude every 15 degrees for a solar term, a total of 24 solar terms, every 30 degrees for a medium air, a total of 12 middle terms.

The day when the sun and the moon are closest to the same line as Bianjing and the moon is between the sun and the earth is the new day, that is, the first day of the month. ”

If there is no medium gas in a month, it will be intercalated.

To put it simply, the first step is to determine the month with the etheric cloud, the new moon is the new moon, the full moon is the fifteenth, and between the two new moons, it is a month.

The second step is to determine the solar terms with the sun, and the longest day is the summer solstice and the shortest is the winter solstice.

The third step is to take the month of the winter solstice as November.

The fourth step is to combine the solar terms and months to see whether there is a leap month, whether there is a leap winter month, and the appearance of a leap wax month.

The fifth step is to determine the first day of the first month according to the winter moon and whether there is a leap month.

Then the cycle, every four years through the leap month, adjust the error of the day, and the 24 solar terms, through accurate calculation and measurement, to ensure that it is not interfered with by the counting of the day and the month, with the yellow longitude, accurately arranged at a certain time and time when it should be.

Compared with the original "Fengyuan Calendar", this calendar is actually inferior in the accuracy of counting the day, but it takes more care of the living habits of the Song people.

In terms of solar terms, it is much more accurate than the original "Fengyuan Calendar".

Because the climate, plant growth, and sunlight are closely related, it is of great significance to guide agricultural production.

There is also a new version of the "Fengyuan calendar", based on observation, every year will make a fine-tuning of the error, this height, indicating that the new calendar has completely mastered the rules of the sun and the moon, no matter how many years in the future, can ensure its accuracy.

Su You patiently explained: "The foundation is done by your old man, we are just adding bricks and tiles to make it more thorough and accurate, now that the new calendar has been revised and improved, I will ask the court for credit to your old man." At this time, how can you go? ”

"Next, we have to follow your train of thought to calculate the solar and lunar eclipses that have occurred in history one by one, this project is also very large, but it is also very important, and it has a milestone-like role in exploring the historical chronology."

In the history books of Chinese dynasties, there is a "Astronomical Chronicle", which records special celestial phenomena.

Being able to accurately deduce the exact time of astronomical phenomena such as solar and lunar eclipses, comet appearances, and fluorescent entry into the palace that occurred in the Central Plains in previous years can provide strong evidence for historical dynasties, which will be a major contribution of science to historical research.

In the minds of the rulers of the dynasty, this article is probably more important than determining the 24 solar terms every year, and countless historical events, especially those that occurred in the three dynasties of antiquity, need to be redefined and interpreted at that time.

Wei Pu took Su You's hand: "Lao Er has been poor since he was a child, lives in the shrine, and takes divination as his profession, and the "Chongtian Calendar" calculates that there will be a solar eclipse in July of the first year of Xining, which is not right. ”

"If it is usual, Lao Er will not say it, the new emperor is on the throne, how can he commit such a big mistake, Lao Er therefore wrote to the Heavenly Supervisor to correct the matter, and then it was as Lao Er said."

"Therefore, I have received the grace of Your Majesty, and I will not be useless because of the disability of the old man, and I will be entered into the Si Tianjian and the "Fengyuan Calendar" will be repaired."

"At that time, Si Tianjian was different from today, ** was full, Lao Er had no help at all, so he could only deduce alone, and it took seven years to get a rough idea."

"Or after the prison sentence arrives, set up an exam, promote talents, and in just two months, the calendar will be revised and perfected, if Lao Er can meet the prison sentence seven years ago, "Fengyuan Calendar", why delay so far? Why is it delayed so far......"

The old man has also been suppressed for too long, and he has a depressed breath in his chest, and today he finally expressed it, and the tears in his blind eyes were bursting, and he couldn't stop it.

Su You also had tears in his eyes, so he comforted him, and at this moment, Shen Kuo rushed over: "Shaobao, Your Majesty has an edict asking you to go to the Privy Council immediately." ”

Su You was shocked: "Western affairs? ”

Now he is Jing Zhaoyin, and the Privy Council summoned him, it can only be because of his qualifications as a military chief in Shaanxi.

Shen Kuo's face also turned pale: "There are rumors in Beijing that Wang Shao will overthrow the army." ”

Su You couldn't help but feel dizzy: "How is it possible?!" ”

Lao Tzu, the butterfly, actually lost the trump card of the Great Song Dynasty in history to attack the Qingtang Dynasty? !

Coming to the door, the people who watched the book in Zhentang were already discussing, Zhang Qi prepared the horse, and Tong Guan gave his hand to Su You: "Shaobao, the official family summons you." ”

Su You turned over and got on his horse: "Go!" ”

The three horses galloped outside the Privy Council, Su You threw the horses to Zhang Qi, and asked Tong Guan, "Is the military report true?" ”

Tong Guan followed Su You and said, "The military report was sent by Captain Guo, and Wang Jingluo has not heard from him for more than a month. ”

Entering the northwest hall of the White Tiger Hall, in front of a huge sand table, Zhao Ji, Wang Anshi, Chen Shengzhi, Cai Ting and others were already discussing.

Wang Anshi saw Su You coming in: "Mingrun is here." ”

Su You arched his hand: "I have seen Your Majesty, I have seen the Prime Minister, the Privy Council, and the Deputy Envoy." ”

Cai Ting said: "It's not a polite time, Guo Kui reported that the prince had entered the Exposed Mountain, and it had been thirty days since then, and there was no return, and he was worried about the situation in Xihe, so he went to the court." ”

Su You said: "Then I'll read the military newspaper first." ”

Cai Ting found the file and handed it to him, Su You read it at a glance, and then asked, "What about the military report in the early stage?" ”

Cai Ting flipped out a bunch of Northwest newspapers: "Here." ”

Su You finished reading them one by one, and the previous recital was very clear, in June, Wang Shao played a play, saying that Shima had cultivated properly and was ready to cross the Tao River again and occupy the peripheral areas of Hezhou, such as Kangle, Jiehe, and Liujiachuan.

At the end of June, the first strategic goal was achieved, and Wang Shao continued to march and occupied Pingqiang City and Xiangzi City again.

By mid-July, Wang Shao had been slowing down the pace of the offensive, stockpiling supplies at Xiangzicheng, while continuing to consolidate the outer areas of Hezhou, once again forming a siege of Hezhou.

At this point, Wang Shao's steps are exactly the same as at the beginning of the year, and it seems that he wants to copy the steps he has gone through again.

However, on July 14, Wang Shao suddenly moved his camp, conquered Muzang City, followed by a U-turn and went south into Taozhou, plunged into Lugu Mountain, and disappeared!
