A thousand-year-old family that began with the Battle of Makino

Chapter 220 Calendar
Han 7th year

In accordance with the usual practice, the Han Emperor ordered the Yuan Dynasty to be changed again.

Han three years

Taichang Baihe wrote a letter, suggesting changing the naming method of the era, abolishing the previous simple number arrangement method, and replacing it with some kind of "Tian Rui" to name the era.

Baihe then named this year's era after "Yuan Ding", and added the reign names of Jianyuan, Yuanguang, Yuanshuo and Yuanshou to the first four yuan. The Han Emperor thought it was a great good thing and immediately issued an edict to officially name it "Yuan Ding". This year is the "Three Years of Yuanding".

Yuanding four years
The Han Emperor set his sights on the south and sent Anguo Shaoji and Zhongjun as envoys to South Vietnam to persuade the South Vietnamese king Zhao Xing to join him.

However, the Prime Minister of South Vietnam, Lu Jia, was unwilling to return to the Han Dynasty.

June
The treasure tripod unearthed in Fenyin was considered an auspicious omen, and the Han Emperor ordered a discussion on the matter of enshrining him in Zen.

Yuanding five years
Lu Jia, the Prime Minister of Nanyue Kingdom, killed the Nanyue King Zhao Xing and his mother, the Han daughter Xi, and proclaimed himself king. Anguo Shaoji, Zhongjun and other Han envoys were also killed.

The Han Emperor ordered Lu Bode, Yang Pu and others to send troops to eliminate South Vietnam and set it up as nine counties including Nanhai County. The threat from the south of the Han Dynasty was thus eliminated, and the Han Emperor turned his attention to the northeast and northwest.

The seventh year of Yuanding (the first year of Yuanfeng)
The Emperor of the Han Dynasty completed the Feng Chan Taishan, a piece of worship to the heavens and Feng Chan written by famous Confucian scholars all over the world. It was burned by the fire and went straight towards the sky.

At the same time, the Han Emperor ordered the change of Yuan Dynasty, which was called "Yuan Feng".

In the same year, because both Wei Qing and Huo Qubing had passed away, the Han Emperor personally led 180,000 cavalry to the north to conquer the Huns. The Xiongnu chanyu hid in Mobei and did not dare to fight. The Han Emperor returned without success.

In the second year of Yuanfeng
The Han Emperor used the world's death row prisoners as soldiers and ordered his lieutenants Yang Pu and Xun Shen to lead the army to attack and destroy Korea.

When North Korea saw the Han army descending, it killed its king Youqu and surrendered. The Han court established four counties including Lelang County.

The seventh year of Yuanfeng (the first year of Taichu)
The Han Dynasty successively targeted the southwestern Yi, annihilating Qielan, Qiongdu, and Chudu, surrendering Yelang and Ranzhu, and establishing five counties including Zangzhou, destroying Laoshen and Mimo, surrendering the Dian Kingdom, and establishing Yizhou County;
Target the Western Qiang, pacify the Western Qiang, and appoint a captain to protect the Qiang;

In response to the capture of King Loulan and Po Gushi in the Western Regions, this year the Han Emperor sent Li Guangli as general to attack Dawan, Luntai, and Yucheng with about 100,000 banished people and evil young men and thousands of national cavalry. They are fighting with them in the Western Region.

May
Taizhong officials Gongsun Qing, Hu Sui, Taishi Ling Sima Qian and others wrote: "Agricultural production in various places has reflected that the current political year is inconsistent with the spring, summer, autumn and winter that people are accustomed to." It is recommended to modify the calendar.

So the Emperor of the Han Dynasty ordered Gongsun Qing, Hu Sui, Sima Qian and others to discuss the creation of the "Han Calendar", and recruited more than 20 folk astronomical scholars to participate, including Zhili Dengping, Changle Sima Ke, Jiuquan County Hou Yijun, alchemist Tangdu, Bai Guotianxing ordered Zhang Hong, Bajun and Luo Xiahong and others.

Baiguo, Chaoge, Taichang Mansion, Tianxingyuan.

This is the highest institution for observing astronomical conditions in the Bai Kingdom. The people inside are all masters who are good at observing astronomical phenomena. Among them, Tianxing Ling Zhang Hong is the most outstanding.

As early as the third year of Yuanfeng, Zhang Hong used instruments to preliminarily speculate on the new calendar in Tianxing Pavilion, the highest peak of Taibai Academy, and simply named it the eighty-one-minute calendar. Too few, and some subordinates have limited abilities.

Afterwards, he reported his findings to Bai Gong's Mansion, which attracted the attention of Taichang Baihe, a powerful man who returned to China to visit his father in due course. Baihe brought part of his findings back to Chang'an and handed them over to Taishi's Mansion for discussion.

This discovery directly shocked Deng Ping, who was in the Taishi Mansion, because this discovery coincided with his discovery, and was even deeper and more accurate than his speculation.

Deng Ping directly approached Sima Qian, the Taishi Ling, and asked him to recommend the great talent who discovered this rule.

Then Sima Qian took him to find Bai He, who wrote a letter, and Deng Ping immediately embarked on the road to the Bai Kingdom.

This discovery has an increasing impact in the astronomical community, because more and more people who are good at astronomical observations have discovered that the current calendar "Zhuanxu Calendar" is no longer suitable for current agricultural production.

Even Xu Gu, the Han court's great agricultural order, wrote to the Han emperor many times. In many places, the best farming opportunities were missed because of the calendar promulgated by the court, resulting in reduced field production or even no harvest. However, they suffered from the lack of new crops. The Han emperor had no choice but to suppress the calendar.

As Zhang Hong's eighty-one-minute calendar spread, scholars from all over the world began to verify the feasibility of this calendar. At the same time, other folk astronomers continued to introduce new calendars based on their own observations and calculations.

However, due to the difference in their respective levels and the differences in the observation equipment they owned, in the end, they had the highest level. The observation equipment was not inferior to that of Zhang Hong of Taishi Mansion in Chang'an, and the laws and calendars he introduced were more popular.

This is also the reason why Gongsun Qing, Hu Sui, Sima Qian and others wrote to the Han Emperor, hoping to gather the power of the world to finalize this matter.

Chang'an, Taishi Mansion
"Gulu Gulu!" A bullock cart stopped at the gate of Taishi Mansion.

An old man with silver hair came down from above. This man was Zhang Hong, the Heavenly Star Commander of the Bai Kingdom.

With the support of his disciples, Zhang Hong slowly walked into the Taishi Mansion. After submitting the official documents, the gatekeepers let them in.

Walking into the designated gathering place, there were already many people here. Some of them were meditating alone in the corner, some were counting with pens on the wall nearby, and some were having a heated debate with others:

"Your calendar is bullshit. I have calculated it. Your calendar does not match the data I observed. According to the algorithm you proposed, there should be no meteors on June 30, the third year of Yuan Shuo. According to My observation is that on this day, there were meteors flashing across the sky, so it’s not accurate!” “My observation is not accurate, so you can guess one for me!”

"I didn't, but I just knew you were wrong."

"You can't be sure even if you don't say it's right? You're actually introducing a new calendar!"

"Aren't you trying to make things difficult for others? Anyway, yours is inaccurate, but the calendar put forward by Zhang Hong, I have speculated, is much more accurate than yours."

"Fart, his calendar is not accurate. I have calculated that there are loopholes in his calendar..."

"Oh? Is there any loophole in my calendar? Please give me some advice!" As soon as Zhang Hong entered the door, he heard someone questioning his calendar. He thought the other party had some new insights.

But when Zhang Hong continued to ask, the man just hesitated and couldn't tell one, two, or three. Zhang Hong understood that he was another person who deceived the world and stole his reputation.

"Brother Zhang!" A call came from behind.

The person who came was a man in his fifties with half-white hair and wearing an official robe.

"Brother Deng!" Zhang Hong saluted slowly. He was on duty in the mansion. Hearing that Zhang Hong was coming, he hurriedly came to charge Deng Ping.

"Brother Zhang, you are finally here. I still have some questions about your calendar, and I have wanted to ask you for a long time." Deng Ping then asked the question, and Zhang Hong did not hide his secrets. The two of them were like this at the door Talked about it.

The people inside who were all doing their own things were attracted by the conversation between the two and gradually gathered around. Listening to the debate between the two most powerful astronomical masters in the world, they felt that if they heard the truth in the morning, they would die in the evening.

Just when Zhang Hong and the two were talking intensely and the others were listening intently, a voice interrupted them.

"No, I don't agree with Mr. Deng Ping's proposal to set up twenty-three solar terms. I think we should follow Mr. Zhang Hong's suggestion and set up twenty-four solar terms, because twenty-two of the one hundred and thirty-five months are food festivals. If the cycle is divided according to the twenty-three solar terms,..."

After hearing the visitor's opinions, Deng Ping felt enlightened and looked at him and said, "Who are you?"

Because the person who came here was really too young, probably only in his early thirties. Due to the difficulty of astronomy, he had to spend a lot of time observing the stars, and he also needed strong financial resources.

Therefore, most of those who are successful in astronomy are old people in their fifties or sixties. There are very few people under the age of forty, let alone those in their early thirties. It is rare to see them in a hundred years.

"People in Baxia County fell into disgrace."

Deng Ping was surprised and said: "Are you Luo Xiahong? No wonder, I have long heard that there is a wizard in Bajun who knows the heavens and geography. He is young and seems to be a gift from heaven. Is it you?"

Luo Xiahong saluted and said, "I don't dare!"

Zhang Hong also asked curiously: "How can you be so in-depth about celestial phenomena at such an age?"

Luo Xiahong said with a smile: "My family has been doing business for generations, and my ancestor was a Miao Niang who was granted the title of fourth-class uncle by Empress Ren. Therefore, she has always been recognized by the people in Bashu. After that, the family business moved to Bajun, where it remains until now."

I have been fond of astronomy since I was a child, and my grandmother was very supportive. She not only invited experts in astronomy at that time to teach me, but also funded me to cast instruments for observing astronomy.

But as I grew older, I felt more and more that the world was a bit strange, so I built an observation device in my hometown of Langzhong, calling myself an armillary sphere. With the help of the armillary sphere, I understood the laws of celestial phenomena more clearly... ·”

As Luo Xiahong talked about his life and the process of inventing the armillary sphere, he also elaborated on his theory of armillary sky and denied the theory that the world is covered with heaven.

This caused a commotion among a large number of astronomical scholars in the academy.

"The earth is round, not square? Fallacy!!!" An alchemist stood up and said excitedly, which was seriously inconsistent with his worldview.

"That's right, you are deceiving the public with your lies. Our ancestors have said that the sky is round and the earth is round. How can it be that everything you say is round? It's ridiculous." Taoist defenders kept jumping out to accuse.

Deng Ping and Zhang Hong did not say anything, because at their level, they already had guesses about whether the earth was round or square, but they did not dare to publicize it. That is to say, Luo Xiahong was young and did not know the importance of it.

"Okay! Today we are discussing the issue of laws and calendars, not the theory of round squares." Deng Ping stopped the group of people from verbally criticizing Luo Xiahong, and took Luo Xiahong and Zhang Hong to other courtyards to continue the discussion.

Just when the three of them were about to enter the courtyard, "Can you take Pindao with you?"

A man dressed in Taoist robes said: "In the lower Tang Dynasty, I have some doubts and opinions about Layman Zhang Hong's eighty-one-minute rule. I hope to discuss it with you."

Deng Ping turned sideways and expressed his invitation to come in, and then closed the courtyard door, no longer caring about the chaos caused by Luo Xiahong's Huntian theory outside.
