Since ancient times, astronomical astrology has been valued by the world, especially the eclipse of the sun and the moon. Only because the rules it performs are related to the two most critical stars, the sun and the moon, so there is a saying that "the experience of the calendar is the experience of the eclipse". That is, through the calculation of solar and lunar eclipses, to verify the accuracy of the calendar.
Li Xin is not an astronomer, but trigonometry itself is closely related to astronomy. The method of using the different shadow lengths of rods to determine seasons and seasons in the calendar has formed a cotangent table. After being fascinated by trigonometric functions, he gradually became more interested in the study of the calendar and the ratio of sunlight and shadow, and he also studied the calculation of solar eclipses along the way.
For him, it was just a little math problem. But for Ge Hong, it is a philosophical and even theological issue. Although he is keen on the Dao, Ge Hong is still a Confucian after all, and the induction between heaven and man in Confucian theory is the interaction between nature and the king's moral issues. Only because a person is not virtuous, will it cause a natural phenomenon. A solar eclipse is one of those serious manifestations.
A mathematician who deduced the occurrence time of a solar eclipse through checking and sneered at the wrong calendar before; encountered a philosopher who believed in the concept of divine punishment, that the solar eclipse is related to the inference of the calendar, but will disappear or appear due to the virtue of the emperor. The so-called "discussion" is bound to not look good.
Li Xin's face became even more stinky: "There is this. I told him that the eclipse limit of the solar eclipse is wrong, and maybe it is because of the influence of the parallax of the moon. He doesn't know the method of functions at all, so tell me about it. It's a lot of trouble, and in the end, I can't argue with me, and you dare to walk away! How can the food limit be calculated as 15 points? It's stupid!"
Liang Feng couldn't understand the food limit and parallax in Li Xin's mouth. But he knew one thing. Li Xin was afraid that he had come up with a new algorithm to calculate the solar eclipse. He turned his head and abused Ge Hong, so that the sullen young man mentioned him with a look of disgust. .
Now is not the time to help them build a relationship. Liang Feng hurriedly asked: "Then next year, will there be a solar eclipse? About when?"
"Yes! More than that, there are three more times!" Li Xin snorted, "The earliest one was on the first day of the first lunar month."
The so-called "solar eclipse is in the new moon, lunar eclipse is in sight", which means that the solar eclipse only occurs on the new moon day of the lunar calendar, which is the first day of the new year. And lunar eclipses only occur on the lunar day, which is the fifteenth. The first day of the first lunar month, the day of the first day of the new year!
Hearing this day, Liang Feng couldn't help but secretly said, God help me too! It is now November, and there are not a few days left until Zhengdan. And the Xiongnu side, in any case, will not send troops to attack Shangdang before Zhengdan. In fact, just after the big defeat, it takes time to prepare food and troops, and the chances of restarting the war in these two months are really low.
What if you do something while a solar eclipse happens? With light shining in his eyes, Liang Feng asked, "I wonder if Zi Le could calculate the exact time of the solar eclipse?"
Three solar eclipses a year are a shocking event, and it is far from the calculation of the calendar. Li Xin was ready to have a fight with Liang Feng. Unexpectedly, this manor had no doubts at all, but instead happily asked the time.
A punch hit the cotton, which made this stunned green a little bit at a loss. Li Xin coughed: "This, I'm afraid it's not very easy to calculate..."
After all, today's astronomy is not developed, and it is very remarkable to be able to release dates. When it comes to the specific time, even if Taishi, who is in charge of the astronomical calendar, comes, I am afraid that he will not be able to tell why.
However, Liang Feng didn't care about this, he bowed to Li Xin and said, "This matter is about the safety of Shangdang, so please give Zi Le a try!"
Although Li Xin is devoted to learning, he doesn't care about things outside the window at all. But he still has a senior brother. These days, he has also been drawn to develop thunderbolt cannons, and he has also heard a lot of terrifying remarks from the Huns. This Shangdang, he stayed comfortable, and the "Nine Chapters of Arithmetic" commented by Master has become the standard teaching material of Chongwen Museum. No matter how different the world is, he knows that it is better to stay here. If the calculation of the solar eclipse can make the Shangdang safer, then why does it matter
After hesitating for a moment, Li Xin scratched the messy bun: "Then I'll try it!"
With Li Xin's words, Liang Feng felt relieved, and immediately asked Yi Yan to return the manuscript to the other party and withdrew from the courtyard.
Standing outside the hospital, Yi Yan frowned tightly: "My lord, what is the relationship between Tiangu Shiri and Shangdang?"
Although he couldn't stand Li Xin's frivolous appearance, after listening to the audience, Yi Yan still understood that the only thing the lord cared about was the time of the solar eclipse. However, when the dog eats the sun, it is too late for others to hide. How can you keep Shangdang by this
"One thing, you are right." Liang Feng sighed, "Unless there is another victory in Lucheng, the Huns will never retreat. If the Huns are allowed to attack, the Shangdang will only be a piece of scorched soil next year, even if they are taken in. All refugees are thrown into the war, and they may not be able to keep the whole territory."
Another point, Liang Feng did not say it directly. Once defeated, the Buddha's halo on his body will be greatly reduced. Without this inspiring protective color, the morale of the Shangdang army and civilians is also extremely terrifying. Let the foundation that was finally laid down was burned to a white ground due to the fire of war. Liang Feng did not want to experience such a thing again.
"Therefore, this opportunity is particularly important!" Seeing the expression on the face of the man beside him, Liang Feng snorted, "If you were to fight in a solar eclipse, would you be afraid?"
Yi Yan was silent for a moment before saying, "If you are the master, your subordinates will not be afraid."
The hidden meaning of these words is extremely simple. If it wasn't for him, Yi Yan probably wouldn't choose to fight at this time. This is the terrifying impact of the astronomical change. Even if you are as brave and brave as Yiyan, you can't completely eliminate the impact of the solar eclipse. Can other people escape
"Then use it well." Liang Feng walked towards the back hall, "This time, we have to set a perfect plan!"
※
It has been a long time since the last time I came to Fuya. Ge Hongduan sat in the guest seat with some uncontrollable confusion in his heart. Liang Taishou has always regarded him as a guest. If something happens, he will go to the Xishan Taoist Temple as soon as possible, and there is no need for him to run errands in person. Such courtesy naturally made Ge Hong extremely useful. Coupled with those fantastic ideas that he had never seen before, he stayed in Shangdang, devoted himself to refining alchemy and studying medicine. Even the fire from the Xiongnu attack did not make him feel the slightest bit about leaving.
But today, the mansion did not go to the Taoist temple, but invited someone to the mansion. How could Ge Hong not be surprised by such a strange move? What is this important, do you want to talk to him in detail
The footsteps sounded, and Liang Feng stepped into the main hall. Dressed in official uniform, with a solemn face. It's been a long time since I've seen him dressed like this, Ge Hong got agitated and stood up: "Fu Jun!"
Liang Feng tucked his sleeves and was sitting on the main seat: "Ge Lang, please take a seat."
He did not call him by the name of the table, but used the name "Ge Lang". Ge Hong was even more puzzled and sat back: "I dare to ask the mansion to invite Hong to come, but is there something wrong?"
"Yes. It's about the party." Liang Feng did not explain, but instead asked, "Ge Langguan worships General Fubo, have you ever thought about becoming an official?"
Ge Hong did not expect to hear such a question. He does have the title of general. He had made military exploits in his hometown before, and the court rewarded him as General Fubo. However, because of the exclusion of fellow villagers and his own background, Ge Hong resolutely took the crown, left the military, and went to Luoyang to seek the Tao. Then came the Shangdang.
He only briefly mentioned some of these things, but the other party never meant to invite him to the curtain, instead he did his best to help him concentrate on his research. If it was a different person, Ge Hong might feel that the other party was despising his talent, and he only wanted to say Dan. But Liang Taishou is not such a person. On the contrary, the man has a heartfelt admiration for all his research. Not because of his background, not because of his words, but only because of his ideals. The way he really wanted and was obsessed with it.
Such a person is enough to know himself. Because of this, Ge Hong, who has always been taciturn, gradually opened his heart. Not only did he discuss Pill Dao and Items with the other party, but he even occasionally talked about the ideas in his heart. The appearance of the Chongwen Museum and the library made him see another method of selecting materials. Don't stick to external things, only recognize talents and virtues. If it is promoted and used by the court, can a southerner like him be able to enter the court in an upright manner, instead of being rejected by the Zhongzheng system and ridiculed and belittled by the northerners who occupy the court
However, Ge Hong never thought of recommending himself to Liang Feng, just because he understood that what the mansion needed was another talent from him. A talent that will not be valued by others, but can save countless lives. In order for more people to live and live in peace, he cares about whether he is an official or not.
But today, Fu Jun actually asked him that!
The heart beat faster, Ge Hong opened his mouth: "I..."
Am I going to be an officer
The clumsy side of words prevailed. Ge Hong was speechless, not knowing how to answer.
Looking at the other party's expression, Liang Feng already knew the answer: "I want to recommend Ge Lang as the county magistrate and settle down."
A county magistrate is no more powerful than a county government official. Although the official is not big, but if you are well-positioned, it is very likely that you will be promoted and transferred to other official positions. This is not like General Fubo, just a general with a miscellaneous title, but a civilian who can govern a place! Can he do it? In other words, is he willing to give up the Taoist temple where he can settle down and become a local official
After pondering for a long time, Ge Hong said: "Does the mansion need me as an official?"
"Exactly." Faced with Ge Hong's question, Liang Feng answered simply, "Shangdang is in a state of turbulence and lacks talents. Ge Lang has been with me for a year, and I also know that Ge Lang is talented and courageous. Brilliant. It's what I need most."
There was no shyness in his words, and he was sincere and decisive.
Ge Hong couldn't help but heat up in his chest: "What about Taoist Temple?"
Do you want to give up all the experiments that are going on now
"If possible, I also hope that Ge Lang can hold several positions. However, since things are urgent, we can only choose one. But Taoism, I will stay for Ge Lang, and I will let those Taoists continue to study. Take it easy." Liang Feng said simply.
Is there a more sincere invitation than this? The warmth in Ge Hong's chest was even stronger. This Liangfu Jun is different from any official he has ever seen. He respected his hobbies, admired his talents, and even pushed open the door, giving him a glimpse of the avenues he had never seen before. Now, he is begging for each other and wants to make him an official. Can he refuse such a request
Ge Hong asked himself, not to mention him, I am afraid that others will not be able to refuse.
Taking a deep breath, Ge Hong said, "Thank you for not giving up, Hong is willing to give it a try!"
Hearing Ge Hong's answer, Liang Feng didn't show a smile on his face. Instead, he was even more awe-inspiring: "Fortunately, Ge Lang agreed, but this county is unusual. It's called Yangyi."
The author has something to say: "Book of Jin" in the first year of Guangxi (306), the first month of Wuzishuo, the seventh month of Yiyoushuo, and the eclipse of the sun. In November, Emperor Hui collapsed. In December, Renwushuo, there is an eclipse of the sun again.
