"Attack, is it right to calculate?"

Technical talents are those who are better than his skills. When Zhao Hao showed his real technology, Jing Zheng naturally changed his name.

"Uh, that's right." Zhao Hao's mouth was a little bitter.

Uncle, do you want to be so spiritual?

It’s fine if the disciples are more comprehensible than me, why are you a silly supporting role so powerful?

But he forgot that he was the national astronomical director.

"So every 6,585 and one-third of the day, the solar eclipse in the previous cycle will appear again. So as long as you know that there was a solar eclipse on a certain day in the past, after such a cycle, almost the same solar eclipse will occur again; similarly, if you push forward for a cycle, there will inevitably be a solar eclipse."

"But because each cycle has a fraction of one-third of the day, this will cause the place where the solar eclipse will move westward by one-third of the earth. So if we want to see the same solar eclipse happen again within the territory of the Ming Dynasty, we have to wait for three cycles, that is, 19,756 days."

After a pause, Zhao Hao brazenly declared: "If you want to narrow the scope to the same province, you need to go through a large cycle, that is, 6,444 months, about 521 years and four months. If you want to ensure the same city 100%, it will have to go through 22,325 months, that is, 1,805 years... Of course, the last one is the obsessive-compulsive disorder of scientists, which can be ignored."

Then he looked at the quick recorder Bei and said, "How is this? Is this simple? Don't worry about it in the future, you can't predict it, right?"

Now even the ministers couldn't help but whisper.

"What he meant is that every 521 years, the solar eclipse will come back to the same place?"

“Is it that simple?”

"Just verify it, it's easy to verify it."

The problem finally came down to the knowledge of the ministers, and all the officials who were as stupid as a gangster became active.

Emperor Longqing also said enthusiastically: "Master Bei, please bring all the solar eclipse records of the Northern Song Dynasty and the National Dynasty."

In official historical books, the records of solar eclipses are particularly important. No matter the dynasty changes, no solar eclipse will be missed.

Fortunately, Manager Bei has made full preparations today and brought all the information he can bring.

Soon, the solar eclipse records of the State Dynasty and the Northern Song Dynasty were found from the file.

Then he and his deputy picked up each other.

~~

In Wenhua Palace, the ministers stretched their necks and saw that the two of them copied the solar eclipse records.

Emperor Longqing couldn't help but get up and walked to the table to check.

I also want to calculate, is that so?

But it seems to be a bit uncountable.

Forget it, don't forget it, just watch it quietly for a while, and then go back and sit down.

After a cup of tea, the two supervisors copied the dates of the solar eclipse of the two dynasties on two large sheets of paper.

"See what Zhao Dizhao said is right." Emperor Longqing, who had already returned to the dragon throne, ordered as if nothing had happened.

"Yes, Your Majesty." Superintendent Bei wiped his sweat and pointed at a solar eclipse and recorded:

"Look at this solar eclipse in July of the 40th year of Jiajing. I will see you in Nanjing this time."

After a pause, he calculated: "If you push it forward for 521 years and four months, it would be..."

After forgetting it for a long time, Chief Bei finally issued a date and said: "It was March of the first year of Kangding in the Northern Song Dynasty."

Because the solar eclipse only appears on the new day, it is enough to just count the month.

I saw the deputy of the Imperial Heaven Supervision quickly browse to the first year of Kangding, and immediately opened his mouth like a ghost.

Duke Cheng, who was standing aside, couldn't stand the slap. He snatched the paper from his hand and said loudly:

"On the first day of the first year of Kangding, the solar eclipse in Jiangning..."

The whole scene in Wenhua Hall was immediately silent, and the emperors and ministers who were originally different in expressions all opened their mouths together.

Only Duke Cheng was still muttering with a little regret: "It's interesting, but the place is not right."

After saying that, he realized that the people around him were all open their mouths, as if they had been imposed on a fixed posture.

Zhao Hao smiled and said, "Duke, Nanjing was called Jiangning during the Song Dynasty."

"Oh, is that?" Duke Cheng laughed awkwardly: "The useless knowledge has increased again."

But he heard Mr. Xu say coldly: "Check another one!"

"Yes, yes, check another one!" The little master couldn't help but walked straight to the table, flipped it with his own hands and said, "Check this."

"Yes!" Bei Peijia quickly looked for another date and said: "In July of the eighth year of Hongwu, solar eclipse can be seen in Beijing."

Superintendent Bei quickly picked up the pen and calculated it. After a while, he wiped his sweat with his sleeves and said, "That's eight years since the Tang Dynasty."

"Let's find Tang Dynasty." Xu Fan shouted coldly, and the deputy of the Imperial Heaven Supervision Department hurried out to rummage the boxes and cabinets.

Taking advantage of this skill, Xu Fan asked Bei Peijia to verify the solar eclipse in Shanxi on the first day of July 22nd year of Jiajing.

After calculation, the corresponding date is March of the fourth year of Tianxi, the Northern Song Dynasty...

When Ji Jian Bei found the record of that year, he actually shouted excitedly, regardless of the little Ge Lao's expression of wanting to eat people:

"On the first day of March of the fourth year of Tianxi, Taiyuan solar eclipse!"

"Wow..." All the ministers were so excited that they were noisy.

The so-called "alone syndrome does not exist" and "double syndrome" is true.

"It seems that there is really a regularity..." Emperor Longqing couldn't stop smiling. Seeing Mr. Xu's blue face, he quickly stopped smiling again.

At this time, the deputy in charge came back with the almanac, and when he entered the door, he shouted: "On the first day of March of the eighth year of Dazhong, there will be a solar eclipse in Youzhou!"

After saying that, he and Guan Zheng Bei didn't care where they were, and they couldn't help but shed tears.

It turns out that predicting a solar eclipse is so simple, but we were so worried that we were bald, but we didn't expect it...

"In fact, more accurate predictions require more complex data and calculations. I will teach you this later."

Zhao Hao said warmly to the two Imperial Heaven Supervision officials who were crying like children.

Well, this is science's respect for the technical talents of the Ming Dynasty.

"Thank you, sir." The supervisory deputy quickly gave a deep gift.

"Thank you, Teacher, for not taking grudges." The supervisor Bei actually kowtowed to Zhao Hao four times in front of the emperor.

"Haha, OK, get up."

Zhao Hao was in a very beautiful mood, so he bowed to the white-faced elder Xu and said:

"In the previous hot air balloon experiment, I accidentally bumped into Yuan Fu and almost tied the old man in it. In order to express my guilt towards Yuan Fu, I have named this cycle 'Huating Cycle'!"

Xu Jie rolled his eyes secretly and said to himself that I thank you, I don’t care.

But the old man had a problem of thinking carefully before speaking, so he heard Emperor Longqing laugh and said:

"Okay, such a good story."

"Uh..." Now that Ge Lao Xu doesn't accept it, he has to accept it.

The officials present also offered rainbow farts, but they couldn't help but wonder, why do you always feel that the old man was being fooled?

"I would like to follow Confucius to kill Shao Zhengmao and kill this villain to see him straight!"

Just as he was in a state of harmony, he suddenly heard a murderous roar, which scared the emperor and the ministers.
