No one noticed that after Chang'an City had just completed a power competition, a new power competition was quietly launched again.

The Imperial Historian's Office, which has long been second only to the General's Mansion, is not only the great power, but also its busyness is no worse than the General's Mansion. The order to go out from here was sent to all parts of the Han Dynasty, and as the war dragged on for a long time, the food of the Han Dynasty became less and less, and the grain in many places had begun to be controlled, and almost every grain of grain was strictly and precisely arranged for when and where to use, and all this was formulated by the Chang'an Bureau.

"Master Hou, Princess Jiangdu has sent a messenger to the country of Lu, it seems that she wants to contact the king of Lu and the Shi family." Sang Hongyang is drawing lines on a huge map of the Han Dynasty, these lines are dense, like the warp and weft of the world, but if you look closely, you will find that most of these lines are finally gathered in Fushi and Guangcheng.

Ah Heng's voice made Sang Hongyang's hand pause slightly, and then he raised his head, looked at the dark night outside the window, and put down the red pen in his hand tiredly.

"The most ruthless emperor's family..... Don't take care of these things in the future, we can't take care of it....." Sang Hongyang sighed and said, for more than a month, Sang Hongyang's original appearance of not being old now has also shown his old state, with deep-set eyes and clear cheeks, coupled with the sparse gray hair, making this imperial historian look like an old man who is close to sixties.

"The villain understands." Ah Heng lowered his head and whispered.

"Forget it, let's go home tonight and rest for the night...... Tomorrow, the armillary sphere will be officially put into operation, and the old man is also curious, what is it that can make the general pay so much attention? Sang Hongyang put down the red pen, stretched a little lazy waist and said.

"It's time for Master Hou to rest for a night!" For the first time, Ah Heng's face showed a look of emotion, only he knew that his own Hou Ye had not had a decent rest for a month.

Sang Hongyang took a carriage to leave the Imperial Doctor's Office and head towards his mansion, it was late at night, there were few pedestrians on Chang'an Avenue, and no one would go out at this time except for some routine patrol soldiers.

The next day's Chang'an City was destined to be very lively, and the completion of the armillary sphere had already become the most important event in Chang'an at present. Not only will the general Huo Guang come to Tianji Academy today, but the imperial grandson and most of the courtiers will also attend, and everyone is curious about what this thing is that the general attaches great importance to?

The officials who can enter the Heavenly Machine Courtyard are at least more than two thousand stones, and some others can only join in the fun outside. However, although it was outside the courtyard, this armillary sphere was too tall and conspicuous, more than three feet high like a three-story attic. Even on Chang'an Avenue outside the courtyard, you can look up and see strange objects made up of several huge metal rings.

These rings are inscribed with patterns and words, as well as a large number of precise scales, which are the main part of the armillary sphere and the change in the position of the stars. In the lower part of the body of these rings, there is a more complex mechanism of speculum tubes and countless metal gears, and no one knows how these gears work, or what happens when they are turned.

Huo Guang stood in the closest place to the armillary sphere, and beside him were Liu Jin, Sang Hongyang and others, and Huo Yan also came on behalf of Emperor Wu of the Han Dynasty. Next to the main body of the armillary sphere's ring, Luo Xia Hong was standing on a high wooden shelf, holding a blank book in one hand and a brush in the other, looking at the armillary sphere seriously. Under the main body of the armillary sphere, there are several Mo disciples standing in different positions, all of whom have some levers or iron cables in front of them, three of them in the middle, and a ring-shaped rudder, which seems to be used to control the armillary sphere.

"Mr. Changgong, let's start....." Huo Guang seemed to be unable to wait, and he said directly to the falling Hong on the wooden frame.

Unlike the curiosity and expectation of others, Huo Guang didn't care about how the armillary sphere worked, all he wanted was the result, the specific time when the lunar eclipse would appear a few months later.

Luo Xia Hong stood on the wooden frame and nodded at Huo Guang below, and then he shouted to a Mo disciple on the armillary sphere, "Open the sluice." ”

With the order of Falling Hong, a Mo disciple on the far left pushed a lever in front of him, and then everyone saw a stream of water began to flow out of a hollow iron pipe, and the water flow was poured into a water tank of the same iron, and there was also a precise scale on the tank, when the water surface rose to a certain height, the Mo disciple pulled back the control lever, and the water flow stopped abruptly.

"Start layering dripping" Luo Hong continued to give instructions, but this time what he said was not understood by many people.

When the order was given again, another lever was pulled, and then the water in the tank began to flow into a thin pipe, along the finger-thick water pipe, the water flow into a funnel-shaped container, and then the container regularly dripped droplets, these water droplets hit the blades, pushing a wheel like a waterwheel, and then the wheel slowly rotated, connected to a ball of vellum paper in the armillary sphere, and the ball was driven to rotate slowly.

At the same time as the ball turned, the three people on the side of the ring rudder in the armillary sphere also put their hands on the rudder, and then the three of them began to push the rudder according to a specific law, and every step they took and each push of the rudder was exactly the same rhythm as the water droplets fell. As the rudder pushed, the huge iron rings on the armillary sphere began to rotate regularly.

Seeing the changes in front of him, Luo Hong's eyes were fixed on the armillary sphere, his gaze moving over the sphere and the spinning ring. As for the others, they were curious and puzzled for a long time, but Huo Guang's expression was slightly moved.

Huo Guang found that there was a red dot on the ball that operated with hydraulic power, and if he combined with the experience of later generations, Huo Guang could see that the position of the red dot was roughly equivalent to the position of Chang'an on the earth. As the armillary sphere rotated, Chang'an's position changed, and the rings representing the stars also changed their positions.

As the armillary sphere turned, Luo Xia Hong also began to write words on the blank page, but he would only write one word at a time, and then he continued to observe the armillary sphere, and after a while he wrote another word, and after repeating this several times, he closed the page and descended the wooden ladder to the ground.

"Living up to the general's trust, the time has been calculated, and it's in it." Luo Hong's respectful hands handed over the book. After a month of hard preparation, countless manpower and material resources were used, and it was this simple time that I was asking for.

There was no anomaly in the operation of the armillary sphere, not even a shock. Except for a few who were thoughtful, most showed a look of disappointment. Because almost everyone doesn't understand what the use of turning twice like this is?

Only Huo Guang's face was excited, and his hands trembled a little when he grabbed the book that had fallen down to record the time. Only Huo Guang understands that this is the power of science and technology, a power that seems to be prosaic, but can fundamentally explain the truth. Without his life's research, without this month's hard work, and without this large amount of manpower and material resources, it would have been impossible to calculate the exact time of the lunar eclipse.

It is a force that cannot be seen to change society in a short period of time, but it is the foundation of human development and the cornerstone of many disciplines in the future.

"Mr. Changgong, I have something important to do, so I will leave first. This day will be Mr. in the future. Huo Guang excitedly bowed to Luo Xia Hong, and in front of everyone, he directly gave the Tianji Academy to Luo Xia Hong. Then, under the stunned gaze of everyone, Huo Guang walked out directly and quickly, got into the carriage that had been prepared outside, and disappeared after a while.

Compared with Huo Guang's ups and downs, the rest of the people were disappointed and went home. In the end, there were only three or five people left in front of the armillary sphere.

The rest of the people, except for Sang Hongyang, the imperial grandson, Huo Yan and Sima Qian, were a young official named Deng Ping.

Sang Hongyang and the others looked at Luo Xiahong very puzzled, just when Sang Hongyang was about to open his mouth to ask the doubts in his heart, the young official's face suddenly became excited, he was originally standing outside the courtyard, and he didn't run in a hurry until the high-ranking officials left. When he looked at the armillary sphere carefully, he didn't care that there was the imperial grandson and the imperial historian in front of him, so he danced in front of these people.

"Haha...... I, Deng Ping, am really fortunate to be able to see such a great holy relic in my third life, and I have no regrets in this life and death...... The heavenly sky is like a chicken, the celestial body is like a projectile, and the earth is like a middle yellow, living alone in the sky, the sky is big and the earth is small. Three hundred and sixty-five degrees and one quarter of the week, and one of the middle of the day, half around the ground, so the twenty-eight nights are half seen and half hidden. The sky turns like the luck of the hub, the circumference is unprovoked, its shape is muddy, so it is called the ..... of the sky" Deng Ping seemed to understand what the truth of the world, like a crazy self-talk, the more he said, the more excited he became, crying and laughing for a while, as if the magic was gone.

Several other people were puzzled by Deng Ping, and his words made everyone even more confused, so they could only look at Luo Xiahong as if asking for help.

"I didn't expect this gentleman to understand the true meaning of the heavens, and I am not lonely, and I am ......" Luo Xiahong did not explain anything to everyone, but praised Deng Ping, who looked like a madman.

Luo Hong's words seemed to make Deng Ping sober up, he no longer danced, his eyes returned to normal, Deng Ping didn't care about the surprised eyes of others, bowed to Luo Xia Hong, and even lifted the hem of his clothes and knelt directly on the ground.

"Today, Mr. Changgong expounded the truth of heaven and earth, and demonstrated the operation of heaven and earth and stars with an armillary sphere, Deng Ping is willing to serve Mr. with the gift of a disciple in this life, please accept my worship by Mr. Changgong!" Deng Ping worshiped as a disciple, and simply regarded Luoxiahong as a celestial, which was an extremely fanatical worship.

"I dare not be ashamed, Your Excellency can see the meaning at a glance, and you are also a fellow Taoist, you and I can be commensurate with Taoist friends." Luo Hong helped Deng Ping up, and he also looked relieved.

A person like Luo Xiahong doesn't care about fame and fortune at all, he is a real Taoist person, and the title of Taoist friend is not a title between Taoist priests as in later generations, but a name between like-minded people who pursue the truth together.

"Huainan Deng Ping has seen a long fair friend." Although Deng Ping is young, he is also the kind of person who really does learning, he doesn't care about what title and seniority, since Luo Hong is commensurate with Taoist friends, he also calls Luo Xia Hong as Taoist friends.

"As soon as Deng Taishi said this, he probably understood the principle of this armillary sphere, and Mr. Changgong also asked Sima Qian to bow down!" After thinking about it, Sima Qian also bowed to Luoxiahong.

Deng Ping is the new Great Han Taishi Ling after Sima Qian.

"Mr. Sima, explain to Lone." Liu Jin asked Sima Qian with a curious expression. Now Sima Qian is the general Sima in the General's Mansion, and he is also an important minister of two thousand stones, but Liu Jin is still used to calling him Mr. Sima, and there is also a meaning that the two are close.

"The will of the grandson, the minister will get an axe in front of Mr. Changgong!" Sima Qian looked at Luo Xia Hong and smiled apologetically. The imperial grandson asked, and Sima Qian, as a courtier, had to answer.

Luo Xiahong smiled and nodded, and also looked at Sima Qian seriously. He knew that Sima Qian was the former Taishi Ling, and the Sima family had been Taishi Ling for generations, and he also had unique insights into astronomy and astronomy.

Then Sima Qian explained the principle of the armillary sphere in a simple and popular way, and the meaning was similar to what Deng Ping said just now, but it was easier for ordinary people to understand. With Sima Qian's simple explanation and image metaphor, Sang Hongyang and others also realized that this seemingly simple thing contains huge truths and knowledge.

"I don't know if Mr. Changgong is convenient to reveal, what did Mr. just record? Why do the generals attach so much importance to it? Sang Hongyang had a superficial taste of these doctrines, he was more concerned about what Huo Guang was calculating with the armillary sphere, and what he was going to do?

Luo Hongyan glanced at Sang Hongyang with some embarrassment, and then he saw that everyone, including the imperial grandson, was looking at him seriously and showing curiosity. Luo Xia Hong thought for a while and said: "The general didn't say that this matter needs to be kept secret, since the imperial doctor asked, the old man will not hide it." From the beginning of the construction of the armillary sphere, the general actually asked for only a lunar eclipse in a few months, and the old man did not know what it was used for! ”

"The time of the lunar eclipse?" Everyone silently repeated this sentence in their hearts, they couldn't understand that what Huo Guang had gotten in the end was just a celestial phenomenon. Judging from Huo Guang's performance just now, that time was very important to him, so important that he didn't want to wait a moment longer to get the time and leave.

When Sang Hongyang and the others were still in Tianji Academy, Huo Guang had already returned to the Hou Mansion quickly. This time he did not return to the General's Mansion, but his home in Chang'an, the Marquis of Anyang.

In the Hou Mansion, Huo Guang closed his study, and at this moment he was writing on the blank book that recorded the time of the lunar eclipse, page by word. What he wrote was no longer a simple letter, as if he were writing a delicate and vast plan.

After a long time, when most of the people in Chang'an City didn't want to talk about the armillary sphere anymore, Huo Guang's study was reopened. Except for a few people who know the true principle of the armillary sphere, most people think that it is a thunderous and rainy, useless thing.

Huo Guang walked out of the study, holding a delicate wooden box in his hand, which was not only sealed with a copper lock, but also sealed with wax in the gaps.

"If you have money, immediately send the most reliable people, send some more people to ensure that nothing goes wrong, and take my jade pendant, send this thing to the Juyan Department, and hand it over to Wu Ya." Huo Guang handed the wooden box to Zhen Youcai, took off the jade pendant on his waist, and solemnly commanded.

Huo Guang had an agreement with Wu Ya that in addition to him himself, only this jade pendant could represent him. In addition, Wu Ya can refuse to carry out the orders of the Li Fan Yuan and even Huo Tang. And the reason why Huo Guang is so solemn is only because there is a book in the wooden box that records the time of the lunar eclipse.

Thank you for the most cute Azi Meow monthly pass, although this thing is really useless for me to hit the street, but in the middle of the night in this autumn cold and drizzle, it is still quite heartwarming!
