Since ancient times, astronomical astrology has been important to the world, especially the eclipse of the sun and the moon. Only because the rules of its execution are related to the two most critical stars, the sun and the moon, there is a saying that "the experience of the calendar, the experience is the eclipse". That is to verify the accuracy of the calendar through the calculation of the eclipse of the sun and the moon.

Li Xin is not an astronomer, but trigonometry itself is closely related to astronomy. The method of using the different shadow lengths of the rods in the calendar to determine the seasons and seasons has already constituted a cotangent table. After being fascinated by trigonometric functions, he gradually became interested in the study of the ratio of the calendar and the sun's light and shadow, and by the way, he also studied the calculation of the solar eclipse.

For him, this is just a small mathematical problem. But for Ge Hong, it is a philosophical and even theological issue. Although he is keen on avenues, Ge Hong is still a Confucian after all, and the interaction between nature and man in Confucianism is the interaction of all things in nature and the moral issues of kings. Only because people are not ethical will cause natural phenomena. The eclipse is just one serious manifestation.

A mathematician who passed the calculations and deduced the time of the solar eclipse, and laughed at the previous calendar error; met a philosopher who believed in the idea of ​​heavenly punishment, and the solar eclipse was related to the calendar inference, but would disappear or appear due to the virtues of the emperor. The so-called "discussion" will certainly not look good.

Li Xin's face worsened: "That's right. I told him that the eclipse limit of the solar eclipse was wrong, and maybe it was because of the moon's parallax. He didn't know the function at all. Tell me Hustle and entangle, but in the end he couldn't argue with me, so he dared to go away! How can the food limit be counted as fifteen points? Stupid!"

Liang Feng didn't understand what the food limit and parallax in Li Xin's mouth were. But he was clear. Li Xin was afraid that he had figured out a new algorithm for predicting the solar eclipse. He turned his head and cruelly tortured Ge Hong, only to make the gourd-like youth mention him with a look of disgust .

Now is not the time to help them build a good relationship. Liang Feng asked urgently: "Then next year, will there be a solar eclipse? About when?"

"Yes! More than there, there are three more!" Li Xin snorted, "The earliest one was the New Year's Day."

The so-called "solar eclipse in the new moon, lunar eclipse in sight" means that the solar eclipse only occurs on the new lunar new day, that is, the first day of the lunar calendar. The lunar eclipse only occurs on the lunar calendar, which is the fifteenth. The New Year's Day is the first day of the New Year, the day of Zhengdan!

Hearing this day, Liang Feng could not help but secretly said, God helped me too! It is now November, and there are not a few days left before Zhengdan. On the Xiongnu side, in any case, they will not send troops to attack the Shangdang before Zhengdan. In fact, just after the big defeat, it takes time just to prepare for food and personnel, and the chances of restarting the war in these two months are really low.

What if something happens during a solar eclipse? With eyes gleaming, Liang Feng asked: "I wonder if Zi Le might calculate the exact time of the solar eclipse?"

Three solar eclipses a year are shocking things to say, and it is far from the calculation of the calendar. Li Xin was ready to fight Liang Feng for a match. Unexpectedly, seeing that this man had no intention of questioning at all, he happily asked the time.

A punch in the cotton made this stunned boy a little confused. Li Xin gave a dry cough: "This, I'm afraid it's not easy to calculate..."

After all, today's astronomy is not too advanced, and it is already quite remarkable to be able to launch a date. When it comes to time, even if Taishi, who is in charge of the astronomical calendar, comes, I am afraid it is impossible to tell why.

However, Liang Feng didn't care about this, he said to Li Xin: "This matter is related to the safety of the Shangdang, please give Zile a try!"

Although Li Xin is devoted to learning, he doesn't care about affairs outside the window at all. But at any rate, he still has a senior, who has also been sent to develop thunderbolt guns these days, and he has also heard a lot of how terrible the Huns say. This Shangdang, he stayed comfortably, and Master's commentary "Nine Chapters of Arithmetic" became the standard textbook of Chongwen Museum. No matter how different the world is, he knows that it is better to stay here. If the eclipse is supposed to make the Shangdang safer, then what's the matter?

After hesitating for a moment, Li Xin scratched the tousled bun: "Then I will 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 small courtyard.

Standing outside the courtyard, Yi Yan's eyebrows frowned tightly: "Master, what is the relationship between Tengu Shiri and Shangdang?"

Although he couldn't understand Li Xin's frivolous appearance, after listening to the audience, Yi Yan understood that the lord was only concerned about the time of the solar eclipse. However, on the Tengu eclipse day, it is too late for others to hide. How can you keep the party with this?

"One thing, you didn't make a mistake." Liang Feng sighed, "Unless there is another victory in Lucheng, the Huns will never retreat. If the Huns are allowed to invade, the Shangdang will be scorched next year, even if they are taken in. If the refugees are all involved in the war, it may not be able to protect the whole territory."

There is another point, Liang Feng did not say directly. Once defeated, the Buddha's aura on him will be greatly reduced. Without this inspiring protective color, the morale of Shangdang soldiers and civilians would be extremely terrible. Let the foundation that was finally laid down, burned to a white ground due to the war. Liang Feng didn't want to experience such a thing again.

"Therefore, this opportunity is particularly important!" Liang Feng said, looking at the expression on the face of the person beside him, "If you are fighting in a solar eclipse, are you afraid?"

Yi Yan was silent for a moment before he said, "If you are the master, your subordinates are not afraid."

The hidden meaning of these words is extremely simple. If it were not for him, Yi Yan would probably not choose this time to play. This is the terrible impact of the astronomical change. Even if you are brave and brave like Yiyan, you can't completely eliminate the impact of the eclipse. Can others escape it?

"Then make good use of it." Liang Feng walked towards the back hall, "this time, we have to set up a perfect plan!"

※

It has been a long time since I visited the government office last time. Ge Hong sat in the guest seat with some uncontrollable confusion in his heart. Taishou Liang has always regarded him as a guest of honor. If something happens, he will go to the Xishan Taoist Temple as soon as possible, and he does not need to run errands personally. This kind of courtesy naturally made Ge Hong extremely useful. Coupled with the fantastic ideas that he had never seen before, he stayed in the Shangdang party, concentrated on refining alchemy and learning medical skills. Even the war from the Huns did not give him the thought of leaving him at all.

But today, the monarch did not go to the Taoist temple, but he was invited to the palace. How can such a weird behavior not surprise Ge Hong? Is there something important to discuss with him?

With the sound of footsteps, Liang Feng stepped into the main hall. An official uniform with a solemn face. He hadn't seen him dressed like this for a long time, and Ge Hong stood up with an agitated spirit: "The mansion!"

Liang Feng rolled his sleeves and sat on the main seat: "Ge Lang, please sit down."

He didn't use the name "Ge Lang" instead. The doubts in Ge Hong's heart were even worse, and he sat back: "Dare to ask the monarch to invite Hong to come, but what's the matter?"

"Yes. It's about the party." Liang Feng didn't explain, but asked instead, "The official Ge Lang worshipped General Fubo, have you ever thought of becoming an official?"

Ge Hong did not expect to hear such a question. He does have a general title. Before quelling the chaos in his hometown, he made military exploits, and the court awarded him as General Fubo. However, because of the exclusion of his fellow villagers and his own background, Ge Hong resolutely took the crown, left the army, and went to Luoyang to find his way. Only then did he come to Shangdang.

He only briefly talked about these things, but the other party never meant to invite him into the scene, but instead did his best to help him concentrate on studying. If you change individuals, Ge Hong might feel that the opponent despise his talents, only Tu Dan said. But Liang Taishou was not such a person. On the contrary, this person appreciates all his research from the heart. Not because of his origin, not because of his tongue, but because of his ideals. He really wanted it, and he was obsessed with the road.

Such a person is a confidant. It is precisely because of this that Ge Hong, who has always been reticent, gradually let go of his heart. Not only did he discuss Dan Dao and Ge Wu with the other party, but he even occasionally talked about the ideas in his mind. The appearance of Chongwenguan and Shuguan allowed him to see another method of selecting materials. Regardless of foreign objects, only recognize talents and virtues. If it is promoted and used by the court, can a southerner like him also enter the court in an upright manner, instead of being rejected by the central government and ridiculed 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 needs is his other talent. A talent that will not be valued by others, but can save countless people. In order for more people to live in peace, he cares about whether he is an official or not.

But today, Fu Jun actually asked him so!

His heartbeat speeded up sharply, and Ge Hong opened his mouth: "I..."

Am I going to be an official?

The side that is weak in words has the upper hand. Ge Hong was dumbfounded, not knowing how to answer.

Looking at the other's expression, Liang Feng already knew the answer: "I want to recommend Ge Lang as the county magistrate and settle down."

The county magistrate is no more powerful than the county officials. Although the official is not big, but when he is well appointed, he is very likely to be promoted and transferred to other official positions. This is not like General Fubo, just a miscellaneous general, but a civilian who can govern a place! Is he competent? In other words, is he willing to give up the Taoist temple that can be settled down and become a magistrate?

After pondering for a long time, Ge Hongcai said, "Do you need me to be an official?"

"Exactly." Faced with Ge Hong's question, Liang Feng answered simply, "The Shangdang is now upset and lacks talents. Ge Lang has been with me for a year, and I also know that Ge Lang has only met people and is courageous. Excellent. It is the good material I need most."

In his words, there is no evasiveness, and he speaks sincerely and decisively.

Ge Hong couldn't help but feel hot in his chest: "What about Taoism?"

Do you want to give up all the experiments that are being carried out now?

"If possible, I also hope that Ge Lang can hold several positions. However, the matter is the first and only one can only choose one. But Taoist Temple, I will stay for Ge Lang, and I will let those Taoists continue to study, never Slowly." Liang Feng said simply.

Is there a more sincere invitation than this? The enthusiasm in Ge Hong's chest is even stronger. This Liang Mansion is different from any official he has ever seen. He respected his hobbies, admired his talents, and even opened the door to let him glimpse the road he had never seen before. Now, he begged each other, wanting to make him an official. Can he refuse such a request?

Ge Hong asked himself, not to mention that it was him, I am afraid that others would not be able to refuse.

Taking a deep breath, Ge Hong said, "Thank you for not giving up, I would like to give it a try!"

Hearing Ge Hong's answer, Liang Feng did not show a smile on his face, but was even more solemn: "Fortunately, Ge Lang agreed, but this county is extraordinary. The name is Yangyi."

The author has something to say: "Book of Jin" in the first year of Guangxi (306) the first month of Wuzishuo, July Yiyoushuo, and the sun is eclipsed. In November, Emperor Hui collapsed. In December, there is another eclipse.
