It happened to be the sixteenth day, and the moon was the roundest. Zhao Yan did not return to the other courtyard after the class in the afternoon, and none of the people who were listening to the class left. The supper was provided directly by Taoist priests in the microscope. Many people even planned to live here tonight. The free rooms in the houses of the village houses in Shangshui Village were almost stolen.

After having supper in the microscope, Zhao Yan immediately came to the Wanfa Hall where he was teaching. A high platform had been set up here, and the telescope that had just been made was also mounted on the stage. The telescope was as thick as a bowl, and the middle was fixed on a rotating bracket. After Zhao Yan climbed onto the platform, he was slowly adjusting the telescope.

In fact, this telescope was manufactured yesterday. Zhao Yan took it to the courtyard for private purposes. Last night, he used this telescope with Cao Ying and others to observe the entire night sky. The most important one was the moon. Speaking of which, although this telescope still has many shortcomings, such as the large color difference, the structure is relatively simple, and the multiple is a bit low, etc., it can clearly see the craters on the moon. Of course, they are all relatively large craters, and the smaller craters are still invisible.

Zhao Yan was fiddling with the telescope on the stage, and the people below were waiting anxiously. The sun had not set completely yet. Although the moon in the sky could be seen, it was not the best time for observation, so they could only wait patiently.

As the sky slowly darkened, the round moon in the sky became brighter. At this time, Zhao Yan could already see the crater on the moon from the telescope, which also made him smile at the corner of his mouth. He looked back at Cao Qi and others standing in the audience. In addition, Ouyang Xiu, Han Qi and others who received the news also came here, and are waiting below now.

Just when Zhao Yan was about to let Cao Qi and the others go on stage to watch one by one, he suddenly saw people outside shouting loudly: "Your Majesty is here!"

When he heard that Zhao Shu had come, not only Zhao Yan was very surprised, but Cao Qi and others also did not expect that Zhao Yan quickly came to the audience and came to the door with Cao Qi and the others to greet him. As a result, Zhao Shu was accompanied by Zhao Xu to enter the courtyard of Wanfa Hall. When he saw Zhao Yan, he immediately laughed and said, "Yan'er, you have done such a major thing. Why didn't you notify your father earlier? If you hadn't learned the news accidentally, you might have missed this grand event!"

"I didn't expect my father to be interested in such trivial matters, and my father was busy with government affairs, so I didn't dare to tell my father." Zhao Yan also smiled and replied. He really didn't expect that observing the moon could alarm Zhao Shu.

"Haha, this is not a trivial matter. The things you talked about during this period have caused a storm throughout the Song Dynasty. Everyone is discussing whether the moon is a big stone? Will it fall if we live on a ball? In addition, why does the earth under our feet revolve around the sun and so on. Even I will hear some such discussions in the court. Today, Yan'er, you said that you can see the true face of the moon with your own eyes. Of course, you cannot miss this opportunity for your father!" Zhao Shu laughed again at this time.

With Zhao Yan's lectures in the microscope, he became famous. Of course, there were many controversies in the content of Zhao Yan's lectures, which was also the consensus of all scholars of the Song Dynasty. However, no matter how controversial it is, Zhao Yan's reputation of erudition and talent has been spread. Everyone was very curious about Zhao Yan, the prince. Zhao Shu was naturally very pleased to see his son gaining such a great reputation based on his talent.

Seeing Zhao Shu so happy, Han Qi, Ouyang Xiu, Cao Qi and others also stepped forward to salute. As a result, Zhao Shu was excited to let them flatten, and then chatted with each other for a few words. Zhao Yan took this opportunity to say hello to Zhao Xu, but at this time, Zhao Xu pulled him and said, "Third brother. Can you really see the moon in your telescope? In addition, there are really no fairies and jade rabbits on the moon?"

Seeing Zhao Xu's anxious look, Zhao Yan couldn't help but feel funny and said, "The moon is extremely desolate, and there is not even the air we can breathe. How could there be any fairy and jade rabbit? Unless the fairy and jade rabbit don't have to breathe."

When Zhao Xu heard Zhao Yan's answer, he couldn't help but look disappointed on his face. He had so many beautiful ideas about the moon. In fact, not only him, but most literati of all generations had unique feelings for the moon, otherwise there wouldn't be so many poems related to the moon. Unfortunately, Zhao Yan now told them the bloody truth. It turned out that the moon, which looked extremely beautiful, was actually a desolate big stone, and there were no fairies or jade rabbits.

"Yan'er, can you see your telescope? I can't wait now!" At this time, Zhao Shu said again. He was not as sentimental as Zhao Xu. For people of his age, the achievements of his children and grandchildren are much more important than the moon.

"Father, you're such a coincidence. The telescope has just been debugged by my son. Now you can see the situation on the moon clearly!" Zhao Yan smiled again. He was still a little confused about who was the first to invite to watch on stage. After all, the identities of Han Qi, Ouyang Xiu and Cao Qi are unusual, but now Zhao Shu has solved this small problem as soon as he comes.

"Haha, then I'm not polite!" Zhao Shu said as he stepped onto the stage, and naturally followed several guards around him. Zhao Yan also stepped forward with him, and then pointed Zhao Shu at the sight of the bright moon in the sky with his telescope. As a result, Zhao Shu was shocked when he just put his eyes on the telescope, but soon he was attracted by the strange craters on the moon.

The telescope designed by Zhao Yan is simple in structure, and the moon seen in the lens is not particularly clear, but even so, Zhao Shu still looked at it for a while before leaving reluctantly. Then it was Zhao Xu's turn to look at it. Although Cao Qi and others behind were anxious, no one dared to urge him.

In contrast, Zhao Xu watched for a longer time because he was still a little unwilling to give up and wanted to find a trace of the life of a fairy or a jade rabbit on the moon, but unfortunately he still found nothing in the end. Finally, after Zhao Xu finished reading it, Zhao Shu and Zhao Xu walked off the stage. Cao Qi and the others immediately rushed to go to the stage to use the telescope, and Zhao Yan had to help them maintain order.

Finally, they waited until several important figures such as Cao Qi finished using the telescope, and then walked off the stage one by one. Although they saw it with their own eyes, they still couldn't believe that the round and bright moon in the sky looked so ugly in the telescope, and the surface was full of scars. Zhao Yan explained to them that it was a circular mountain range, and the moon palace and fairy that were all rumored on the moon were not visible at all.

When Cao Qi and Han Qi finished reading, it was the turn of ordinary people who came to listen to the class. In order to be able to use the telescope tonight, these people had already drawn numbers before, and everyone had to go on stage with the numbers. And because there were too many people, there were also restrictions on the time for everyone to use the telescope.

Zhao Yan, Cao Qi and others accompanied Zhao Shu to a meeting hall for a microscope to rest. It was not until this time that Zhao Shu suddenly spoke: "Yan'er, I heard that the circle-like things on the moon are actually mountains. Why are these mountains so strange?"

"Your Majesty said so much. I also think that the mountains are very strange. Can the prince know how they were formed?" Han Qi also asked at this time. From the moment he saw the true face of the moon, he and Ouyang Xiu and others have been in a trance. Although Zhao Yan had already talked about some of the situations of the moon to the point where he heard it, he could not compare with the shock he saw with his own eyes.

"There are two main reasons for the formation of craters on the moon. The first is similar to the eruption of volcanoes on our earth. The second is the impact of meteorites on the moon..." Zhao Yan briefly introduced the formation of craters. Fortunately, everyone here is knowledgeable, so he can understand Zhao Yan's explanation.

"So that's it. I didn't expect that most of the craters were smashed by meteorites. If there was no such obstacle, they would probably fall on the earth where we live." Zhao Shu couldn't help but speak after hearing Zhao Yan's explanation.

"Father, the moon is wise, and the moon is indeed circling around the earth like a guard, so for such a planet, we live in a satellite, and some other planets in the solar system also have satellites, and there are more than one, so if someone can reach those planets, they may see multiple moons in the sky." Zhao Yan smiled and said when he heard Zhao Shu's words.

After chatting about the moon for a few words, Zhao Shu should go back at this time. After all, as the emperor, it is not easy to be able to come out at night. If he doesn't leave, Han Qi and Ouyang Xiu will probably stand up and persuade him. Zhao Shu knows this very clearly. Instead of letting others rush, it is better to leave on his own initiative.

At present, Zhao Yan, Cao Qi and others sent Zhao Shu away together. Han Qi and Ouyang Xiu would also go to court tomorrow, so they returned to the city with Zhao Shu. As for the moon viewing activities in front of the Wanfa Hall, it still continued. It seems that as long as the moon does not fall, the enthusiasm of those people will never fade.

After seeing Zhao Shu off, Zhao Yan wanted to go back and rest. The telescope had been adjusted. He just needed to fine-tune it as the moon moved. He didn't need to do anything else. In addition, he was a little tired after teaching a day. He yawned and left to Cao Qi. Everyone was so familiar with him. Zhao Yan didn't ask them to send him off, so he left with his guard.

However, just as Zhao Yan just walked to the microscopic front yard, he suddenly heard a familiar voice coming from the corner of the front yard saying: "The prince stays!" (To be continued, please search for astronomy, the novel is better, updated and faster!
