Young Eunuch Qin breathed a sigh of relief, no matter where the new system was wrong, at least he didn't make a mistake. No matter how precise the instruments made by the pen and the fun www.biquge.info and the pavilion are, there may be errors and omissions, but the sun in the sky will never be wrong. The newly made timekeeping instrument, no matter how delicate it looks, must be tested by the sun in the sky. The simple table is unpretentious, but it is the most accurate measure to test time.

"Click-" A large bead of sweat fell to the ground and disappeared in the blink of an eye.

Yang Weide didn't dare to wipe his sweat, his eyes didn't dare to blink, and he stared at the shadow cast by Gui on the table. He has even lost his senses, everything is instinctive. At the moment when Kei's shadow on the table was the shortest, he waved his arm mechanically.

A crisp bell rang, and sound waves rippled in the hot air, causing ripples.

All the officials and students of Si Tianjian sighed, if it was a game, they would have won.

"Noon has arrived, the leakage is accurate, and there is no error!"

The sound came down from the observatory, hitting Ouyang Xiu's ears like a big bell, he only felt his head buzzing, and he couldn't help but hold Shi Quanbin beside him, and his steps staggered.

"Officials, be careful! Look at your pale face, isn't it heat stroke? There is medicine in the car, take a sip! ”

Shi Quanbin supported Ouyang Xiu and asked the people around him to go to the car to get medicine.

Young Eunuch Qin secretly let out a long breath, carefully put the official hat on his white-haired head, and watched Yang Weide slowly walk down from the observatory with a serious face.

In front of Young Eunuch Qin, Yang Weide said in a deep voice: "The time on the engraved pendulum has passed quickly, and it is not in line with Gui Biao!" ”

Young Eunuch Qin nodded: "It's five tenths of a quarter faster, it should be correct!" ”

"Yes, it's a little more than half a quarter faster-" Yang Weide nodded blankly, "More than half a moment, how can this be?" Xu Beizhi, Yan Beizhi, and many people in Si Tianjian participated, how could they make such mistakes and omissions? They've been checking for a long time, and they shouldn't have made such a mistake! Before we left, we deliberately missed the school with the carving in front of the Xuande Gate, and there were no accidents along the way, it shouldn't be, it shouldn't! ”

Ouyang Xiu took the medicine handed over by Shi Quanbin, raised his head and took a sip, frowning and said, "This is medicine?" How does it smell so big! Ah, it feels stronger than the usual drinking! ”

Shi Quanbin said with a smile: "This is Huoxiang Zhengqi Water, when the Marquis of Yongning County was in Yongzhou, thanks to this medicine to relieve miasma, I heard that there are a lot of living people!" It is good to have wine in the medicine, and it is very effective in relieving the heat. ”

Ouyang Xiu was suspicious, drank the medicine, and felt that his brain was clearer.

Before the two returned to the pendulum, Ouyang Xiu asked Yang Weide and Young Eunuch Qin: "How is it?" Is the moment of the pendulum wrong? ”

Yang Weide nodded: "If you look at it, the pendulum is more than half a quarter faster!" ”

"More than half a moment!" Ouyang Xiu took a breath of cool air, "How can the leakage used by Si Tianjian be more than half a moment?" This, that's too much of a difference! How do we go back and confess? At this moment, is it still placed in the Luoyang Division Heavenly Prison? ”

Yang Weide shook his head gloomily and did not speak. The difference of a few days is more than half a quarter, so the pendulum cannot be used at all. Maybe like what Xu Ping did before, it is okay to put it in people's homes, but Si Tianjian is absolutely unacceptable. Not to mention more than half a moment, even a tenth of the heavenly prison can't accept it.

Ouyang Xiu was dumbfounded, and he didn't know what to do for a while. Before leaving, Xu Ping also specially ordered him to take this trip as the main thing, but he didn't expect to encounter such a tricky thing, what should I do?

Seeing that everyone was calm and did not speak, Shi Quanbin said: "Officials, I don't know if you still remember what the Marquis of Yongning County ordered before the prison?" ”

Ouyang Xiu smiled bitterly: "What words?" The system said that this trip was mainly for me, but I didn't know what to do? Is it possible to ask Young Eunuch Yang to adjust the time of the pendulum to the same as the engraving leak on the observatory, and then slowly compare? ”

"It must not be adjusted!" Yang Weide flatly refused. "Before leaving, wait for the system to be specially ordered, not allowed to adjust the time!"

Shi Quanbin took the hands of the two and said, "That's not what I said, do you remember that the marquis said such a sentence." In this world, not only are the regions different, but the time of day is not necessarily the same, and anything can happen. ”

Ouyang Xiu's eyes lit up: "It seems that Xu Zhizhi really said that—yes, he did say it!" ”

Thinking of this, Ouyang Xiu and Yang Weide glanced at each other: "Could it be that Xu Beizhi has already thought of this section?" The reason why there are errors and omissions in the pendulum is not because the timing is inaccurate, but because the time of day in Kaifeng and Luoyang is different——"

Speaking of this, Ouyang Xiu closed his mouth. This question is not easy to talk about, there is a total of one day, and there must be a suitable explanation for the different times of the day, and it is not dare to guess. If you talk nonsense without thinking clearly, you will be seen as frivolous.

Shi Quanbin said: "No matter what, I think the marquis must have something in mind." Before leaving, he repeatedly instructed us to record in detail what we saw, how to arrange it, and how to do it when we arrived at the place, and then report back to him when we returned. We have no result here, in my opinion, it is better to watch like this, let me watch here, you two write a pleading, ride back to the capital on horseback, and report this matter to the waiting system, how about it? ”

Ouyang Xiu groaned: "It has to be like this? ”

Young Eunuch Qin stood aside with a straight face and didn't say a word. The day is a day, and I have never heard that the time will be different when the place is different, and the time of day will change with the place? However, he is already old and has never been in charge of the Si Tianjian in the capital, so he has no say in this kind of matter. Then he stopped talking and waited to see how it got better.

Yang Weide said: "This matter cannot be delayed, it has been transported to the place, and it cannot be placed here all the time, how to deal with it in the end, we must come up with an idea as soon as possible." When the chief of the stone pavilion mentioned it, I also remembered that this time we traveled Xu Beizhi repeatedly explained that we had to be cautious, as if we realized something. You must know that Xu Zhizhi is a person who has led troops to fight in the past, and he has always disliked verbosity, and this exception is definitely not unintentional. ”

At that moment, several people discussed, and it was decided that Shi Quanbin would stay in place with the armor and watch the carving, and Ouyang Xiu and Yang Weide would ride fast horses back to Beijing. After reporting to Xu Ping, he will make a decision.

In order to avoid omission, Ouyang Xiu asked Qin Shaojian to take a pen and paper, found a shady place next to it, and wrote the pleadings by himself. Several people present read it correctly and drew a monogram together.

The two took two guards with them, so they borrowed two good horses from the armor and rode back to the capital along the post road.

******

"So miserable?" In the small flower hall in the Yongning Waiting Mansion, Xu Ping looked at Ouyang Xiu and Yang Weide, their clothes were untidy, unkempt, and they were all emaciated, and they were really a little surprised.

Ouyang Xiu arched his hand: "Waiting for the system, this time the three of us sent the carved pendulum to the Luoyang Division Heavenly Prison, where did I think of the place, after the test, the new carved pendulum and the old Luoyang carved leakage time can not match." ”

Xu Ping's expression was calm and he asked, "Oh, is it fast or slow?" ”

When Yang Weide saw Xu Ping's appearance, he felt a little bottom in his heart, knowing that he might already know it, and replied: "Waiting for the system, it's fast, it's about half a moment faster." ”

Kaifeng is in the east of Luoyang, according to the direction of the earth's rotation, it is normal to be faster. The two places are three or four hundred miles apart, and more than half a quarter is converted into about seven or eight minutes in Xu Ping's previous life, which happens to be the time difference between the longitudes of the two places.

As for whether the jet lag will be found after the pendulum is transported to the Luoyang Division Heavenly Prison, it turns out that Xu Ping has no bottom in his heart. Theoretically, it should have been discovered, but who knows if there are any accidents that they haven't considered? In his previous life, you would have traveled between the two cities in a car with your watch, and it would have been impossible to detect the jet lag.

Who can be sure in this era? Xu Ping didn't specialize in working in Si Tianjian.

So when these people were leaving, Xu Ping repeatedly told them to be cautious, not to make their own decisions, and to report back to themselves for everything they encountered, which is the truth. Now that they came back and said the time difference between the two places, Xu Ping's heart had a number, and this time it undoubtedly proved the existence of the time difference between the two places in the world.

Seeing Ouyang Xiu and Yang Weide looking at him blankly, Xu Ping smiled: "As long as you don't make any mistakes on the road, then everything happens is normal." I remember saying that two places in the world are not only geographically different, but also may have different times of day. In fact, time and geography are inextricably linked. ”

Ouyang Xiu frowned and said, "To be made, Kaifeng and Luoyang will really meet the different times?" Can the two places be different? ”

"There's something strange about the different times of the day, as long as you walk enough to pay a little attention to it. For example, when I used to be in Yongzhou, I found that the length of days and nights there was very different from that of the Central Plains. One day and one night are the same twelve hours, and in the same season, the days in Yongzhou are longer than those in the Central Plains, and the nights are shorter. Ouyang Xiu, in the future, when you go to other places as officials, if you really work hard in everything, you should find that these are. For example, like Yan Zhizhi, he is more attentive than others in the place, so he will see that the tide is related to the circle of the moon, and he will make a lotus drain. ”

Speaking of this, Xu Ping couldn't help sighing: "People who read often say that learning is nothing more than physical life. But speaking of which, there are many people who are attentive to the study of life, and there are very few people who are attentive to physics. If you don't know the time and geography, how can you know the life of the human heart? Physical life, both are indispensable! If you rot your legs on the same level, this knowledge will be discounted. However, in the study of life, pedantic scholars thought that as long as they sat in the study and read the books of the sages, they could become well-educated Confucians. But I don't know that the reason why a sage is a sage is that learning can make people in later generations look up to the mountains, but it is not something that sits in the study and reads it. Traveling thousands of miles, seeing thousands of people, observing the geography of mountains and rivers, changing at four times, learning comes from here. - Alright, you go down and wash up first, and then we'll talk. ”

(Note: In ancient China, of course, it was not only China, there was no national unified time, it was all local time, which was different from our current time.) Local prefectures and counties all use the principle of Gui Biao to measure the noon of each day, and then divide one day and night into twelve hours with carving, and the official office has a special person in charge. According to the principle of jet lag, as long as you carry a slightly more accurate clock, you will actually notice the jet lag. The main reason for the difficulty in finding out is the lack of accurate timekeeping tools. Of course, if the timekeeping tools were more precise, the solar time would have been found under the system at that time, including the difference between true solar time and peaceful solar time, as well as sidereal time, and these contents would not be covered in the book.
