"Your Highness, do you want to take a look at the moon with your own eyes? It will be dawn soon. If you don't look at it, you won't be able to see it today." Cao Zheng said again.
"No need." Min'er said.
"Would you like to see what the real moon looks like?" Yun Neng understood Min'er's thoughts and asked the other children without saying much.
He thought that Wen Qi or Wen Tou would be the first to rush up, but what he didn't expect was that Wen Luo was the first to walk up to another clairvoyant and lowered his head to look. This clairvoyant was the same as Yun Yong's. The frame has also been adjusted so that the moon can be seen immediately.
Wen Luo stood behind the clairvoyant and watched for a long time. It was not until the sun slowly rose and the moon disappeared that he withdrew his eyes and murmured in a low voice: "The moon is actually like this."
"Yes, the moon is like this. It is completely different from what the literati thought in the past." Yun agreed with a smile.
"But, father, why does the moon revolve around the earth? And why does the earth revolve around the sun?" Wen Luo suddenly asked.
The smile on Yun's face froze. He thought that Wen Luo, like Min'er, was lamenting the destruction of myths in the past, but he didn't expect that she was actually thinking about this.
"Your Highness, these Gezhijian are also studying, but there are no results yet." Cao Zheng replied.
"That's it." Wen Luo muttered again without saying anything else.
‘Is Wen Luo so concerned about astronomy? I’ve never noticed it before. Ask Xiyao or Xiyi later.’ Yun thought in his mind.
"Father, after seeing all this, what is the final conclusion that you are very concerned about?" Wen Qi asked at this time. Although it is amazing to actually observe what the moon and the Milky Way look like, it has no practical significance. Okay, so what was deduced in the end that made Yun very concerned?
"There's no hurry, we still need to observe the last thing in the sky." Yun came back to his senses and smiled.
"It's already dawn, what else can we observe?"
Yun smiled and said nothing. Cao Zheng replied: "Your Highness, what I want to observe next is the sun."
"Observe the sun?" Wen Qi said suspiciously: "Looking at the sun all the time can burn your eyes. Could it be that looking through clairvoyance won't burn your eyes?"
"That's not the case." Cao Zheng explained: "Even looking through clairvoyance will burn your eyes. Therefore, observing the sun is not to look directly with your eyes, but to project the reflection of the sun in the house and observe the reflection in the house." As he spoke, he pointed to the projector beside him and said: "Use this together with clairvoyance to project the reflection of the sun in the house. The sun has just risen at this time, and the reflection projected is dim, so you have to wait a moment. A moment."
"It can still be done like this." Wen Qi stepped forward and looked at the projector carefully and said, "How can this thing project the reflection of the sun on the ground?"
"Your Highness, I can't explain it at the moment. If Your Highness is willing to know, I will explain it to Your Highness after observing the reflection."
"No need. I'm just curious for a moment." Wen Qi said and stepped back.
Afterwards, the children chattered about the real Milky Way and the Moon, and speculated on what special features they would see when observing the sun later. Yun Ze communicated with the officials of Gezhi Prison and asked them how they could ensure that the final conclusion was correct. He also asked Gezhi What else does the supervisor need?
Cao Zheng patted his chest to ensure that the conclusion was absolutely correct, and immediately listed the equipment needed by Gezhijian. Now His Majesty made a comment, and the person who served as Minister of Industry was Yang Shiqi, who had been the supervisor of Gezhijian for five or six years. He would not get stuck in his neck. Of course, we must take advantage of this opportunity to get everything we want.
Yun didn't even look at it. He wrote the word "quasi" on it and stamped it with a seal he carried with him. He handed it back to Yang Zhu and said to him: "Take this to Shi Qi and ask him to send it to you." All these things are given to you.”
"Your Majesty, in fact, there is no need for these many things for the time being." Yang Zhu was a little frightened when he saw so many things on the list and said.
"Just approve it first, so you can ask me for orders when you can." Yun said nonchalantly. Seeing that Yang Zhu was still a little worried, he said seriously: "Gezhijian is very important, not only for navigation, but also for the research and development here in the future. The things are also important to other aspects. I will not stop supporting Ge Zhijian for any reason. Don’t worry, Aiqing.”
"I accept the decree." Yang Zhu saw Yun saying this. Although it was strange, he was not worried that Yun would take it out on him when he gave up Gezhi Prison, so he bowed and agreed.
Yun said a few more words to them, glanced at the roof, and said with a smile: "The sun has risen so high, it's time to observe it."
"Yes." Cao Zheng agreed, and he and Sichengtang moved the clairvoyant and the projector together, pushed open the east roof and put the clairvoyant up, adjusted the position and then closed the roof, leaving only one room that could accommodate just enough space. The gap in the clairvoyant tube made the room very dark. Seeing this, Min'er subconsciously tensed up and hugged Wen Luo tightly. Sichengtang adjusted the direction of the projector, aligned it with the clairvoyant, and turned on the projector.
In an instant, a yellow scene appeared in the room, and part of the sun was projected onto the ground. Even after passing through the projection, it illuminated the room and reflected everyone's faces.
Wen Qi and others were startled at first, and then looked at the projection on the ground carefully. But after a while, Wen Qi asked: "Dad, what can you see in this?" Except for the yellow, there was nothing but yellow. Although it was novel to be able to observe the sun in this way, Yun couldn't let them watch it just because of the novelty.
"Don't be anxious." Yun said, and then said to Sichengtang: "Zoom in."
Sichengtang immediately increased the magnification of his clairvoyance, and the sun projected on the ground became even bigger, encompassing everyone inside, and many people's bodies were also yellowish.
But Wen Qi looked at it for a while and still didn't find any difference. He was about to speak again, but at this moment Wen Qi suddenly said: "Sister, what is that under your feet?"
"What is what?" Min'er subconsciously took a step back, and everyone also looked at where she originally stayed. At this glance, Wen Luo saw something different: "Why is there a black spot here?" She asked as she asked. As he said that, he broke away from Min'er's arms, walked back and wiped it on the ground twice.
"Hey, why can't I erase this black spot?" she asked again strangely.
"Could it be that this black spot is on the sun and not on the ground?" Min'er said subconsciously.
"How could this happen?" Wen Qi asked, "How can there be black spots on the sun?"
"How can there be no black spots on the sun?" Wen said: "We still don't know what the sun is and why it can emit light. What's so strange about having black spots on it?"
"Well," Wen Qi was speechless for a moment and didn't know how to answer. Wen Ze continued: "Before closing the roof just now, I took a look at the eldest sister's feet. There was no such big black spot. It can be seen that it must be on the sun."
"There are such black spots on the sun? It's really strange." Others (mainly the guards) couldn't help but started talking: "Why is there such a thing on the sun?"
"Isn't it said that the sun is just a big fireball? It burns brightly all day long. Is this the remaining firewood that the immortal put into the fireball?"
"The sun is much bigger than the earth. It is a small black spot on the ground. I don't know how big it is on the sun. It is at least one foot square, maybe ten feet square. How can there be such a big firewood left over?"
"Who knows what immortals use to make firewood? Maybe the firewood in the sky is many times bigger than that on the ground."
"Ahem!" They were discussing in full swing when Yun coughed and everyone stopped talking. In fact, they all knew the rules and knew they shouldn't talk too much, but they couldn't help but start talking after seeing such a magical sight just now;
At the same time, the princes did not say anything and made their voices obvious. Now that they were reminded, they immediately understood that they should not speak, and they all stopped talking.
"Sichengtang, open the roof, don't look anymore." Yun ordered again. Sichengtang vaguely agreed, only to hear a "click", the yellow hall disappeared, and the room became bright again.
.
"It feels better to keep the light on." Wen Qi couldn't help but whisper.
"Your Majesty," Cao Zheng explained: "What the Sixth Prince of the Emperor just discovered is what I want to show to Your Majesty and Your Highnesses. The sunlight is not very strong now. If the sunlight is more dazzling, you can see it more clearly."
I saw this thing. Because this thing appeared pitch black on the sun, I called it a sunspot."
"But sunspots are not just black dots or squares. If you use clairvoyance to the maximum extent, you can see that different sunspots look completely different, and they are weird and indescribable."
