No one noticed that after just completing a power competition in Chang'an City, another new power competition has quietly begun.

The Censor's Office has long become the second only to the General's Office. It is not only because of its great power, but also because of its busyness. The orders from here were sent to all parts of the Han Dynasty. As the war dragged on longer and longer, the Han Dynasty's food became less and less. Many places have begun to control food, and almost every grain of food was strictly and precisely arranged at the time and where to use it. All of this was formulated by the Chang'an office.

"Marty, Princess Jiangdu sent a messenger to Lu State, as if she wanted to contact King Lu and the Shi Family." Sang Hongyang was drawing lines on a huge Han map, which were densely packed, like the latitudes of the world. However, if you look closely, you will find that most of these lines were 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 imperial family... don't worry about these things in the future, we can't care about them..." Sang Hongyang sighed. For more than a month, Sang Hongyang's appearance, which was not old, now shows an old look. His deep eyes and clear cheeks, and his white hair, made the censor look like an old man in his sixties.

"The villain understands." Ah Heng lowered his head and responded in a low voice.

"Forget it, go back to the house to rest for a night... The armillary sphere will be officially activated tomorrow. I am also curious about what the general can pay so much attention to?" Sang Hongyang put down his pen and stretched his waist and said.

"It's time for the Marquis to have a good rest!" Ah Heng's face showed a touch of emotion for the first time. Only he knew that his Marquis had not had a decent rest for a month.

Sang Hongyang left the office of the Censorate in a carriage and headed towards his mansion. It was late at night. There were few pedestrians on the streets of Chang'an. Except for some soldiers who were patrolling on routines, no one would go out at this time.

The next day, Chang'an City was destined to be very lively, and the completion of the armillary sphere has long become the most important thing in Chang'an at present. Not only will the Grand General Huo Guang visit Tianji Academy in person today, but the Grandson of the Emperor and most court officials will also attend. Everyone was curious about what this thing was highly valued by the General?

At least two thousand stones can be entered by officials who are more than two thousand stones. As for others, they can only join in the fun outside. However, although they are outside the courtyard, this armillary sphere is too tall and conspicuous, more than three feet high like a three-story attic. Even on Chang'an Street outside the courtyard, you can look up and see a strange object composed of several huge metal rings.

These rings are engraved with patterns and words, and there are a large number of precise scales. It is the main part of the armillary sphere, which is also something that shows the changes in the position of the astrological signs. At the lower part of the main body of these rings, there is a more complex precision device composed of a spy tube and countless metal gears. No one knows how these gears operate, nor what changes will happen after they rotate.

Huo Guang stood nearest to the armillary sphere. On his side were Liu Jin, Sang Hongyang and others, and Huo Xian also came on behalf of Emperor Wu of Han. Next to the ring body of the armillary sphere, Luo Xiahong was standing on a high wooden frame. He held a blank book in one hand and a brush in the other hand, and looked at the armillary sphere seriously. Under the armillary sphere, several Mohist disciples stood in different positions. These people had some levers or iron cables in front of them, including three in the middle and a circular steering wheel, which seemed to be used to control the armillary sphere.

"Mr. Grandpa, let's start..." Huo Guang seemed to be unable to wait, and he said directly to Luo Xiahong on the wooden frame.

Unlike other people's curiosity and expectations, Huo Guang did not care about how the armillary sphere operated. All he wanted was the result, the specific time when the lunar eclipse appeared several months later.

Luo Xiahong stood on the wooden frame and nodded to Huo Guang below. Then he shouted to a Mo family disciple on the armillary sphere: "Open the water gate."

With Luo Xiahong's order, a Mo family disciple on the left pushed a lever in front of him. Then everyone saw a stream of water flowing out of a hollow iron pipe. The water flow was poured into a sink of the same iron. There was also an accurate scale on the sink. When the water surface rose to a certain height, the Mo family disciple pulled back the control rod and the water flow stopped abruptly.

"Start layering and dripping" Luo Xiahong continued to issue instructions, but this time few people could understand what he said.

When Luo Xiahong's order was issued again, another joystick was pulled, and then the water in the water tank began to flow into a thin tube. Following the water pipe as thick as a finger, the water flowed into a container shaped like a funnel. Then the container drips drop by droplets. These water droplets hit the blades, pushing a wheel like a water wheel. Then the wheel slowly rotated, connecting a ball of paper in the armillary sphere, and the ball was driven and rotated slowly.

Just as the ball was rotating, the three people on the edge of the ring-shaped spiral disc in the armillary sphere also put their hands on the spiral disc, and then the three people began to push the spiral disc according to specific rules. Every time they took a step, every time they pushed the spiral disc, it was exactly the same as the rhythm of the water droplets. With the push of the spiral disc, the huge iron rings on the armillary sphere began to operate regularly.

Seeing the changes in front of him, Luo Xiahong stared at the armillary sphere with his eyes closed, and his eyes kept moving on the sphere and the rotating ring. As for the others, they were curious and puzzled for a long time, only Huo Guang's expression was slightly moved.

Huo Guang found that there was a red dot on the sphere that was operated with hydraulic power. If we 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, the position of Chang'an was changing, and those rings representing astrological signs were also changing positions.

As the armillary sphere rotated, Luo Xiahong began to write one text on the blank page, but he only wrote one word at a time, and then continued to observe the operation of the armillary sphere. After a while, he continued to write another word. After repeating this several times, he closed the page and went down the wooden ladder to the ground.

"I have lived up to the general's entrusted time, and it's here." Luo Xiahong handed it to the book with respectful hands. He worked hard for a month and used countless manpower and material resources. What he wanted was this simple time.

There is no vision in the operation of the armillary sphere, and it is not even shocking. Except for a few people who are thinking, most people show disappointment on their faces. Because almost everyone doesn’t understand what the use of turning a few times is like this?

Only Huo Guang's face was excited, and his hands were trembling as he grabbed Luo Xiahong's book of time. Only Huo Guang understood that this was the power of technology, a power that seemed dull but could fundamentally explain the truth. Without Luo Xiahong's lifelong research, without this month's hard work, without this large amount of manpower and material resources, it would never be possible to calculate the exact lunar eclipse time.

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

"Thank you, Mr. Grandpa, and I have important things to do, so I will leave first. The Tianji Academy will be the teacher in the future." Huo Guang bowed to Luo Xiahong excitedly. In front of everyone's eyes, he even gave Tianji Academy to Luo Xiahong directly. Then, under the astonishment of everyone, Huo Guang walked out quickly and got on the carriage that had been ready to be outside. After a moment, he disappeared.

Compared to Huo Guang's popularity, the rest of the people returned home with great disappointment and disappointment. In the end, only three or five people were left before the armillary sphere.

Apart from Sang Hongyang, the crown prince, Huo Xian and Sima Qian, the remaining few people were a young official named Deng Ping.

Sang Hongyang and others looked at Luo Xiahong in confusion. Just as Sang Hongyang was about to ask for a question, the young official named Deng Ping suddenly became excited. He was originally standing outside the courtyard, but he hurriedly ran in after the senior officials left. When he looked at the armpit sphere carefully, he didn't care about the royal grandson and the censor in front of him, and he actually danced in front of these people.

"Haha... I, Deng Ping, have been fortunate in my life, and I was able to see such a great holy object. I have no regrets in this life and death... The sky is like a chicken, the body is like a projectile, and the earth is like a yellow in the middle. I live alone in the sky, the sky is big and the earth is small. The sky is 365 degrees and one quarter of the quarter, and it is also one in the middle, half around the ground, so the twenty-eight constellations are half seen and half hidden. The sky is like the luck of the car hub, and the circumference is endless, and its shape is muddy, so it is called Huntian..." Deng Ping seemed to understand some of the world's principles, and he said to himself like a madman. The more he spoke, he became more and more excited, crying and laughing as if the demon was stunned.

The others were all confused by Deng Ping, and his words made everyone confused and could only look at Luo Xiahong like help.

"I didn't expect that this gentleman could understand the true meaning of the world. My way is not alone..." Luo Xiahong did not explain anything to everyone, but instead praised Deng Ping, who was crazy.

Luo Xiahong's words seemed to have awakened Deng Ping. He stopped dancing and his eyes returned to normal. Deng Ping did not care about the surprised gazes of others. He bowed to Luo Xiahong, and even lifted up his clothes and knelt directly on the ground.

"Now Mr. Meng Changgong explained the ultimate principles of heaven and earth, and used the armillary sphere to demonstrate the movement of heaven and earth stars. Deng Ping is willing to serve the disciples in this life. Please accept my worship!" Deng Ping worshipped Luo Xiahong as a god. This is an extremely fanatical worship.

"I am ashamed of being accused of being accused of it. You can see the meaning of it at a glance. You and I can only be called a fellow Taoist." Luo Xiahong also helped Deng Ping up, looking relieved.

People like Luoyanghong don’t care about fame and fortune at all. They are truly Taoist people. The name of fellow Taoists is not the name of Taoists in later generations, but the name of people who share the same minds and pursue the truth together.

"Deng Ping in Huainan has met a righteous fellow Taoist." Although Deng Ping was young, he was also the kind of person who was really a scholar. He didn't care about his name or seniority. Since Luo Yanghong was called a fellow Taoist, he also called Luo Yanghong as a fellow Taoist.

"After saying this, I will probably understand the principle of this armillary sphere. Mr. Chief, please accept Sima Qian's bow!" After some thought, Sima Qian also bowed to Luo Xiahong.

Deng Ping was the new Grand Historian of the Han Dynasty after Sima Qian.

"Mr. Sima, please explain to me." Liu Jin asked Sima Qian with curiosity. Now Sima Qian is the General Sima in the General's Mansion, and is also an important official of 2,000 stones. However, Liu Jin is still used to calling him Mr. Sima, and he also means that the two of them are close to each other.

"The Grandson's order, then I will show off my skills in front of Mr. Grandson!" Sima Qian looked at Luo Xiahong's apologetically smile. The Grandson asked, Sima Qian, as a minister, must answer.

Luo Xiahong nodded with a smile and looked at Sima Qian seriously. He knew that Sima Qian was the former Grand Historian, and the Sima family has been Grand Historian for generations, and also had unique insights into astronomical astrology.

Then Sima Qian briefly explained the principle of the armillary sphere in a simple and simple way. The meaning is similar to what Deng Ping said just now, but it is easier for ordinary people to understand. With Sima Qian's in-depth explanation and vivid metaphors, Sang Hongyang and others also realized that the seemingly simple things contained in them were actually extremely huge.

"I wonder if Mr. Gao is convenient for me to disclose what he just recorded? Why did the general attach so much importance to it?" Sang Hongyang tried these theories briefly. What he was more concerned about was what Huo Guang used the armillary sphere to calculate and what he planned to do?

Luo Xiahong looked at Sang Hongyang with some embarrassment when he heard this. Then he saw that everyone, including the Crown Prince, looked at him seriously and showed curiosity. Luo Xiahong thought for a while and said, "The General did not say that this matter needs to be kept confidential. Since the Censor asked, I will not hide it. From the beginning of the construction of the armillary sphere, what the General asked for was just a lunar eclipse several months later. As for the purpose of it, I don't know!"

"The time of the lunar eclipse?" Everyone was silently repeating this sentence in their hearts. They couldn't understand that Huo Guangda finally got only a time of astronomy after much trouble. Judging from Huo Guang's performance just now, that time is very important to him, so important that he didn't want to wait for a moment and left.

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

Huo Guang closed his study in the marquis's mansion. At this moment, he was writing in a blank book that recorded the lunar eclipse time, word by word, page by page. What he wrote was no longer a simple letter, as if he was writing a precise and huge plan.

After a long time, when most people in Chang'an City didn't want to talk about the armillary sphere anymore, the people in Huo Guang's study opened it again. Except for a few people who know the true principle of the armillary sphere, most people think it is a thing with heavy thunder and little rain, and uselessness.

Huo Guang walked out of the study and held an exquisite wooden box in his hand. Not only was there a copper lock on the wooden box, but it was also sealed with wax in the gap.

"Youcai, immediately send the most reliable people and send more people to ensure that everything is foolproof. Take my jade pendant and send this item to Juyan tribe, and hand it over to Wuya." Huo Guang handed the wooden box to Zhen Youcai, then took off the jade pendant around his waist, and solemnly ordered.

Huo Guang once made an agreement with Wu Ya that except for him who came in person, only this jade pendant could represent him. In addition, Wu Ya could refuse to execute the orders of the Lifan Academy and even Huo Tang. The reason why Huo Guang was so solemn was because there was a book in the wooden box that recorded the time of the lunar eclipse.

Thanks to the cuteest A Zimiao's monthly ticket. Although this thing is really useless to me like this, it is still quite heartwarming in the late night of the cold autumn drizzle!
