However, what Zhao Yan didn't expect was that he had just answered Ouyang Xiu's question, but he saw that the contemporary Heavenly Master Zhang Sizong sitting next to Cao Yan suddenly stood up and said, "Your Royal Highness, Poor Dao is also very interested in things outside the solar system, I wonder if you can tell us more?" ”

"What Brother Zhang Dao said is good, Poor Dao is also very interested in things outside the solar system, and I also ask the county king to help me solve my doubts!" At this time, I saw Liu Mingkang, who was on an equal footing with Zhang Sizong, also asked with a solemn face. ＋◆

Looking at Zhang Sizong and Liu Mingkang standing below, Zhao Yan suddenly felt that the expressions of these two people were a little too strict, which made him feel strange, but since these two people wanted to know the situation outside the solar system like Ouyang Xiu, Zhao Yan couldn't refuse anymore, so he had to talk about the Milky Way outside the solar system, and finally the universe composed of countless galaxies.

For the understanding of the universe, Zhao Yan is not an astronomer after all, he only knows some general situations, and his understanding of the universe is very limited even in future generations, so Zhao Yan can only pick out some things he knows and tell them, the most important of which is to tell them the vastness and mystery of the universe.

"There are many explanations of the universe, and some people say that the universe is a unity of time, space, energy, and matter, and that it exists objectively. It is also said that the universe is actually a product of our visual and tactile senses, a world of thinking, which only depends on people's will and exists objectively. Of course, you may not understand what I say, but you just need to know that there are too many secrets in this universe waiting for us to explore, excavate, and discover! Zhao Yan finally concluded again that there is no unified definition of the universe in later generations, and he can only copy the explanations seen in some materials in later generations, as for whether Cao Tong can understand it, it is none of his business.

Zhao Yan uses too many new terms in his explanation of the universe. Ouyang Xiu and the others all seemed to understand it, but Zhao Yanxian, Zhang Sizong and Liu Mingkang were obviously relieved, the two and Cao Tong glanced at each other, and then they both showed a knowing smile, as if they had put down a big stone in their hearts?

Next, Zhao Yan continued to ask questions from the people below, because Zhao Yan had promised to let them see the true face of the moon with their own eyes. So these people stopped dwelling on this issue for the time being, and began to ask all kinds of questions, most of which were about some questions in the solar system, and Zhao Yan also answered them one by one, and other people couldn't ask Zhao Yan these questions when they saw them, and each question was explained very reasonably, which made these people who listened to the lecture believe in Zhao Yan's theory again.

Seeing that it was not early, Zhao Yan was about to announce that today's class was over, and he would come to give a lecture tomorrow afternoon. But at this time, he saw Shen Kuo, who had not spoken, suddenly stood up and asked: "King Jun, just now you said that you can let us see the true face of the moon with our own eyes, but it will take a while, I want to ask how long you have to wait?" ”

In fact, among the people listening to the lecture below, Zhao Yan valued Shen Kuo the most, because he felt that others might not understand, but Shen Kuo, as the greatest scientist of this era, would definitely understand, and Shen Kuo had not asked any questions just now. This made Zhao Yan even more convinced of his own judgment, and now he heard that he was anxious to see the moon with his own eyes. This also made Zhao Yan smile slightly: "If you want to see the moon with your own eyes, you need something called a telescope, this kind of thing is not easy to make, but Daomen has solved a big problem, and now it is much easier to make a telescope, wait a minute, I will discuss it with Daomen." It should not take more than a few days, as long as the telescope can be built, the surface of the moon can be seen. ”

"Telescopes? Could it be ......" Cao Yan was stunned for a moment when he heard Zhao Yan's words, and then couldn't help but say excitedly, he had already thought that this kind of telescope should be related to glass. Actually, it's not just him. Zhang Sizong and Liu Mingkang next to him also thought of glass and microscopes, especially the magic of microscopes, which made them believe in Zhao Yan's words even more.

"I see, thank you King Jun!" Shen Kuo immediately bowed to Zhao Yan deeply, he knew that Zhao Yan was very knowledgeable before, and even he was ashamed of himself, but until today, he didn't appear, Zhao Yan is simply an unknown treasure, and the knowledge that flows from him is simply endless, which also greatly satisfies his desire for the unknown.

After Shen Kuo sat down, although there were still people who wanted to ask questions, it was not early now, so Zhao Yan did not answer any more questions, but announced that today's class was over, and the content he would talk about tomorrow would be mathematics, if everyone was interested, they could continue to come to listen to the class.

After Zhao Yan finished speaking, he finally ended today's lecture, and the people who listened to the lecture below also stood up and saluted him, and then waited until Zhao Yan left, and these people left 6 times, but Zhao Yan did not leave the Taoist temple, but waited for Cao Yan to come out to discuss the telescope.

Before Zhao Yan sat down to take a sip of tea, he saw Cao Yan, Zhang Sizong, and Liu Mingkang hurriedly breaking in, Zhao Yan just wanted to talk about the telescope, but he didn't expect Cao Yan to be the first to say: "Son-in-law, we didn't understand your explanation of the universe we are in today, can you explain it to us again?" ”

Zhao Yan thought that Cao Tong would talk about the telescope first when he saw him, but he didn't expect him to ask about the universe, which made him a little puzzled, but he still tried his best to explain it in words they could understand, in fact, for the universe, the mainstream explanation in later generations is that the universe is the unity of time, space, energy and matter, which is also a materialist explanation. The other is the more idealistic interpretation, which is that the universe is only a product of our visual and tactile senses, and objectively exists in our minds. There are many proponents of this explanation, and even many scientists agree with it.

That is, when Zhao Yan just finished finishing the above two explanations, he suddenly saw Cao Tong laugh and said: "That's right, that's it, that's what we need!" ”

"Hahahaha, I thought that as soon as this doctrine of the king of the county came out, our Daomen and Buddhism would be hit by a huge blow, but now it seems that it is the endless Daomen of our Daomen, and we can even take advantage of this to take a step ahead of the Buddhism, and when the bald donkeys wake up, I'm afraid it's too late to change." Liu Mingkang also laughed proudly at this time, and Zhang Sizong next to him also smiled.

"You...... What do you mean? Zhao Yan asked with a confused face at this time, he still couldn't understand what Cao Tong and the three of them were happy about?

"Hehe, how can the king of the county not understand, according to what you said, there is no moon palace and fairies on the moon, and there is no heaven and gods and Buddhas in the sky, so there must be many people in the world who think we are deceiving, so what the king of the county said today is not a good thing for our Daomen or Buddhism, but the universe that the king of the county talked about later gave us new ideas, maybe our Daomen's eyes can not be limited to the earth, but to focus on the entire universe, since the universe is so vast and mysterious, Is it possible that the immortals created this universe, and is it possible that the universe is where the immortals live? At this time, Liu Mingkang replied, with a somewhat dirty smile on his face.

Zhao Yan heard Liu Mingkang's words, especially the last few sentences, and looked at them with a shocked face, it turned out that the so-called religion was actually like this, and the first thing that came to mind after listening to what they were talking about was to make up for the huge loopholes in their teachings.

Cao Yan was also a little embarrassed at this time, and immediately coughed dryly and said to Zhao Yan: "Son-in-law, although the astronomy and geography you talked about today have not been confirmed, we all believe that you will never lie to us, but what you said conflicts with some things in our Daomen, and if our Daomen wants to survive, we have to change with the times." ”

Zhao Yan finally came to his senses when he heard Cao Yan's words, and immediately looked at Cao Tong and the three of them a few times, and suddenly laughed unexpectedly: "I see, but grandfather, your brain is really flexible, and you actually thought of expanding the pattern of Taoist mythology, so that you can be one step ahead of Buddhism, maybe you can really turn over and press Buddhism under you." ”

Zhao Yan was really not angry about Cao Tong and their use of the content they preached to enrich the Taoist teachings, and even he appreciated Cao Tong very much for their courage to think and do, and it is not a bad thing to have faith, at least it can make people's spirits have a sustenance, not like later generations everywhere to look at money, for money, fame, power and other things, you can sell anything, and there is no bottom line in doing things, that kind of society is undoubtedly very terrible in the eyes of Zhao Yan now.

Seeing that Zhao Yan was not angry, but also expressed his great appreciation, which made Cao Yan and them all breathe a sigh of relief, what they were most worried about was that Zhao Yan would disagree, and even debunk their teachings, but now they can finally rest assured.

Of course, it is not easy for Cao Tong and them to revise their teachings, especially Taoism has many schools, and the mythological system is also a little chaotic, and it is not easy to add new things to this chaotic mythological system, or even completely change it, but Cao Tong has long been prepared enough, as long as the idea is settled, it is natural to concentrate the elites in the Taoist sect to improve.

After the matter of Daomen was finished, then Cao Tong finally remembered to ask Zhao Yan about the telescope, Zhao Yan had already prepared for this, and immediately asked Ya'er to prepare a pen and paper, and then drew a sketch of the structure of the telescope, and explained to Cao Tong some things that need attention, Cao Tong saw that the structure of this telescope was not complicated, and he patted his chest at the moment and assured that it would only take seven days at most, and it could definitely be manufactured.
