The warm sunlight shone into the Zichen Hall through the color-matched glass panes that had just been installed for a few days, leaving a few obvious pillars of light in mid-air.

There are fine dust floating in the air, especially in the area of the beam of light, which can be seen very clearly. Especially when someone walks around, or speaks loudly, you can even see the dust rolling like a stream of water.

Zhang Qian, the secretary and the young eunuch, kneeling less than two feet beside Zhang Shuo, the squire of the military department, watched the changes of dust in the range of the pillar of light without blinking, and his young and fair face was as calm as a statue in a temple.

It wasn't that he was deliberately slipping away, but what was being discussed in the court was far beyond the scope of his knowledge. What white scripture, yellow scripture, into the lodging, and going to the pole, are all nouns that he has rarely heard of before. And ancient astronomical theories such as "heaven, fire, earth and water intersect, yin and yang are born" made him even more unconscious!

In Zhang Qian's view, the calendar is a calendar, and in another time and space, whether it is the lunar calendar used by the Chinese people in the past, or the Gregorian calendar used in the world, it is just a tool for marking and calculating time. Except for making people remember some special days and displaying solar terms, it has no other function, let alone any profound connotation.

And at this moment, everyone else in the court may not agree with his point of view. In particular, those "calendar revision factions" headed by Zong Chuke have raised the accuracy of the calendar to the height of the rise and fall of the country. It seems that a few more lunar eclipses or solar eclipses will lead to disasters from above the heavens and the collapse of Datang in an instant.

The "maintenance faction" led by Wei Juyuan cited a large number of examples to prove that the "Lin De Calendar" still has the advantages that no calendar in the world can surpass. In particular, in the estimation of solar terms and the positions of the five stars of metal, wood, water, fire, and earth, there is little difference between the calculated results and the actual observations of the Heavenly Prison.

"What is called is very small, but because of the distance, even if the position changes, it cannot be observed on the armillary zodiac." Lu Zang suddenly stood up with a hint that he didn't know who he had gotten and launched a fierce attack on the evidence of the "maintenance faction".

This was a bit of a fuss. The armillary zodiac is the crystallization of the sincere cooperation between the armillary eunuch and the general eunuch more than 40 years ago, led by Li Chunfeng. It is composed of three bronze rings, which can be easily observed and measured in the position of most stars in the sky, and can even be estimated and displayed in advance. For so many years after the successful manufacture, many neighboring countries wanted to imitate it, but because they could not guarantee the concentricity of the ring, they had to give up one after another.

And today, Lu Zang used a sentence to deny the artifact that Hun Tian Jian and the general would be the most proud of for decades, how could the officials of the Hun Tian Prison and the prison be the prison endure this breath? Immediately, they pointed the finger at him and scolded him sharply, "Nonsense, Lu Shilang, it's okay if you don't understand, but don't say anything!" ”

"Hehe, Lu Shilang, your director is not here, so don't speak casually!"

"Lu Shilang, isn't this a poem, nor is it a valley in the mountains?"

"Lu Shilang, the cuckoo in Zhongnan Mountain has bloomed again. Where are the hermits in the mountains in the past? ”

……

"From the location of the Moon Palace, you can know that Lu's words are true!" Lu Zang used half of his skills, all in one mouth. Therefore, without hesitation, he launched a counterattack, "Why is the moon position observed by the armillary sphere repeatedly different from the results estimated by the Lin De calendar?" There is no other reason, the Moon Palace is close to the ground, and the change in position is easy to see. And the five-star, waiting for you to wait on the armillary sphere can see that its position is different from previous years, I am afraid that it has gone to its original position for more than 10,000 miles! ”

The words fell, and there was immediately a rebuttal around them. The officials of the Heavenly Prison were eager to drown Lu Zang alive with saliva.

"Although this guy is annoying, what he says is very reasonable." Zhang Qian didn't quite understand what the officials of the Heavenly Prison were saying, so he could only judge who was right and who was wrong on both sides of the dispute based on the knowledge he possessed.

There is no doubt that from a purely scientific point of view, Lu Zang's words make more sense. The moon is indeed much closer to the earth than the five planets of gold, wood, water, fire, and earth. This is common knowledge in the twenty-first century, which is known to almost all children, and there is no need to argue at all.

However, Zhang Qian didn't want to open his mouth to help Lu Zangyong speak. The reason is very simple, first, he knows that the five planets are farther away from the earth than the moon, but he doesn't know how to prove it. Second, long before coming to participate in the pursuit of the dynasty, Zhang Jiuling had already given him enough reminders.

As far as Zhang Qian knows, in the history of another time and space, Zhang Jiuling also served as a prime minister. Therefore, he believes that Zhang Jiuling's sensitivity to politics far exceeds that of himself, an official. Since Zhang Jiuling already suspected that Zong Chuke suddenly grabbed the defects of the "Lin De Calendar" at this juncture, it may be that he has other intentions. He couldn't make himself confused, and he jumped into the whirlpool!

Since he didn't want to get involved in the vortex, he could only continue to observe how the dust within the range of the pillar of light moved. As the weather gets hotter, the airflow is slowly rising. So, the dust floats upwards most of the time. The position of the pillar of light was from the center of the Zichen Hall to the right, and it slowly moved to the left at a speed that could not be distinguished by the naked eye. This means that the sun has set in the west and evening is coming!

"What about Li Chunfeng, he also said at the beginning that the Lin De calendar can be used for 800 years, but it is only forty-three years, and even the first and fifteenth years of junior high school can't figure it out!" Suddenly, someone sneered loudly in the Zichen Palace, causing the dust in the pillar of light to roll left and right as if it had been swept by a stick.

Zhang Qian's interest was interrupted, and he frowned and looked up, just in time to see Sha Chongyi's familiar face. Sure enough, there is someone in the court who is good at being an official, Zhang Qian remembers that last autumn, this person was demoted to the rank of a certain pastoral supervisor because of slandering himself. Unexpectedly, just a few months later, this person actually put on the official uniform of Shangshu Province again, and he also had the qualification to participate in the pursuit of the dynasty. (Note: Shangshu Province records, from the seven products.) ）

And Lu Zangyong, who had quarreled with the officials of the Heavenly Prison before, had retreated to the side at this moment. Looking at his smug face, it was clear that he had the upper hand in the last round of disputes.

"Thanks to Lao Tzu, the secretary and young eunuch, he is a position with no real power, and he doesn't need to come to the court meeting often! Otherwise, maybe one day I can't help it, and I will jump up and pump people with a big-eared scraper! Not wanting to see Lu Zang with that smug face, Zhang Qianqian secretly muttered in his heart and turned his head quickly.

Where the eye swept over, there were tired or helpless faces. Obviously, most of the people present did not want to get involved in the whirlpool like him. However, there was no way for everyone to escape from the Zichen Palace. Therefore, they can only be patient and sit on the ground in a daze.

"Li Chunfeng served as Taishi Ling for more than 30 years, and was named the male of Changle County by Gaozong. The "Ten Sutras of Calculation" compiled by him is a compulsory course for my Tang Dynasty Guozijian. Someone suddenly stood up and reminded with a sneer, "Sha Lushi, you look down on Li Taishi so much, I don't know what writings you have, can you take them out for me to read?" ”

"This ......" Sha Chongyi suddenly blushed with shame, but he resolutely refused to admit defeat. gritted his teeth and emphasized loudly: "Sha is talking about things." The mistakes of the "Lin De Calendar" are obvious to all. It can't be because its formulator is Li Chunfeng, it will not be easy for eternity! ”

Although there is a suspicion of diverting the argument, there is nothing wrong with it itself. Especially from Zhang Qian's point of view, all scientific theories, as long as there are deviations in practice, can be questioned, even if the person who put forward the theory is a sage.

However, the "maintenance faction" led by Wei Juyuan, the chief supervisor of the secret arts, did not think so. While launching a personal attack on Sha Chongyi, he defended the "Lin De Calendar". It is argued that the fact that the New Moons and Moons of certain months in each year do not coincide with the phases of the Moon is due to the fact that when the Lunde Calendar was first formulated, the method of moving forward or backward the New Year to ensure that there would not be several major months in a row. As long as you wait for three or five months, the new day and the sunset in the almanac will coincide with the moon phase again. (Note: New Year's Day, that is, the first day of the new year.) Looking at the sun, i.e. the fifteenth)

"What's there to argue about, make a statistic about how many of last year's New Year's Day and Wangri do not match the phases of the moon, and soon know whether the "Lin De Calendar" will correct the error by itself?" The more Zhang Qian listened, the more bored he felt, so he changed his kneeling posture and quietly turned his gaze to Zhang Shuo, who was closest to him.

was about to secretly mumble a few words to Zhang and listen to the other party's point of view. But he was surprised to find that Zhang Shuo was carrying a carbon strip and sketching on the wat board. The text that fell on the wat board was not a meeting minutes, but a seven-character poem.

"Uh-huh, cough-cough, cough-cough......" Sensing Zhang Qian's snooping on him, Zhang Shuo quickly put away the wat board and coughed in a low voice.

"It turns out that the famous minister of Kaiyuan also has a time to slip away from meetings!" Zhang Qian snickered in his heart, and quickly looked away, not continuing to annoy people.

He was about to continue to observe the floating dust in the pillar of light, but in his ears, he suddenly heard the voice of Shi Zhongji, "Shengshang, Weichen thinks that it is pointless to continue to argue. Since Hun Tianjian insists that the Lin De Calendar is still accurate and usable, why not compare it with the Nine Execution Calendars that have been introduced to Chang'an along with Buddhist scriptures in recent years? As for the New Year's Day, Wangwang and the lunar eclipse of the next month, if the "Lin De Calendar" can presume these three days accurately, then there is no need to mention the words of the calendar. If the "Lin De Calendar" is wrong for three days, but the "Nine Calendars" are accurate, the "Nine De Calendars" will be replaced by the "Lin De Calendar". lest I continue to make mistakes and make my Tang calendar a laughing stock of the world! ”
