Before Yao Doudou finished speaking, the little emperor asked very suspiciously.

"Aren't the sun, moon and stars so big, what else can we see in full?"

After the little emperor finished speaking, Yao Doudou shook his head slightly.

"Your Majesty, do you remember what the minister told you about the extraterrestrial things last time, in this vast universe, the earth we are in is actually very small, although it is larger than the moon, but it is pitifully small compared to the sun, just because we are at different distances, so it looks small, just like we look at the people in the distance are very small, this is the truth."

After Yao Doudou finished speaking, the little emperor also nodded slightly, feeling that what Yao Doudou said was not unreasonable.

"I see, the Heavenly Maiden is really knowledgeable, and I am ashamed of myself."

For the humility of the little emperor, the queen also smiled at the bottom.

It was almost dusk at this time, and the moon had risen from the eastern sky, Yao Doudou pointed the astronomical telescope at the location of the moon, and a large white orange appeared on the lens of the astronomical telescope.

"Your Majesty, what is presented in the astronomical telescope at this time is the full picture of the moon, and please take a look at it Your Majesty."

After Yao Doudou withdrew from the exam, he made a gesture to the little emperor, and the little emperor leaned down and aimed one eye at the eyepiece of the astronomical telescope.

Just when everyone was curious about what could come out of this tube, the little emperor was so frightened that he sat down on the ground, and beads of sweat the size of beans appeared on his forehead.

The queen was also at a loss when she saw that the little emperor was frightened, and for a while, the palace people in the attic were also panicked.

"Your Majesty, what's wrong with you?"

The queen lifted the little emperor from the ground, and the little emperor lifted his crown, looking a little panicked.

"This ball in here...... What is it. ”

Yao Doudou felt a little strange at first, and when the little emperor said the ball, he smiled.

"Heavenly Maiden, what the hell is going on, why are you still happy."

The queen said with a serious face, and Yao Doudou arched her hand to the little emperor and the queen.

"Your Majesty, the telescope you looked at before should be able to see people and things dozens of miles away clearly, and this astronomical telescope can see things thousands of miles away clearly, of course, this must be without obstruction, so it is best to use him to observe the trajectory and shape of the stars in the sky, this ball is the moon."

As soon as Yao Doudou said this, the little emperor swallowed his saliva, if others said so, the little emperor would definitely pull him down to play a hundred boards, and then hand it over to Dali Temple, but Yao Doudou has a pivotal position in the little emperor's mind.

"So it was, but I saw that the moon in the sky was bright and clean, and it was so ...... The astronomical telescope is indeed pitted and uneven. ”

Regarding the little emperor's doubts, Yao Doudou went on to explain to the little emperor, saying that there is no vegetation on the surface of the moon, only hillside dust, so when the sun shines on the moon, the moon will reflect the sun's rays.

When Yao Doudou said this, the little emperor seemed to understand it, and the queen felt that what the Heavenly Maiden said was very reasonable.

"That'...... Is the story of Chang'e running to the moon a false rumor? I saw that there seemed to be no palace above the moon, and there were no pedestrians. ”

The little emperor tidied up his clothes again as he spoke, and Yao Doudou didn't know how to answer the little emperor's question, so he just nodded slightly.

The queen walked in front of the astronomical telescope and leaned over to observe the eyepiece, and sure enough, a white sphere like a large willow orange appeared inside, and when the queen raised her head, she found that the position of the astronomical telescope was the moon.

"Heavenly Maiden, since this astronomical telescope can see the stars thousands of miles away, it should also be able to see other stars."

The queen said happily, and Yao Doudou nodded yes.

"The brightest star than this, the scientific name of this star is Venus."

Yao Doudou pointed the telescope at Venus again, and a golden sphere appeared in the eyepiece of the telescope.

After the queen and the emperor finished reading Venus, they let out a sigh of admiration.

"I really didn't expect that such a small tube could see the whole picture of the stars, what is that...... Celestial Maiden, you said that the earth we are on is a spherical shape, and I still don't believe it, but now it seems that this is indeed the case. ”

The little emperor swung the telescope again as he spoke, pointing it at the moon, and the queen also showed a knowing smile beside him.

"By the way, the Heavenly Maiden, the people of the Taishi Bureau often observe some strange celestial phenomena, so how can you explain it?"

When the little emperor said this, Yao Doudou continued.

"Actually, the Earth we live on is just a member of the solar system family."

Yao Doudou said and made a comprehensive science popularization to the little emperor and queen, and the little emperor and queen were also very interested in listening to Yao Doudou's words, what they didn't expect was that this extraterrestrial thing turned out to come out of Yao Doudou's mouth, and it was not so obscure.

"What the Celestial Maiden said really made me and the queen suddenly open, I thought that this vision of the sky must be a warning to the world, but now it seems that it is just some ordinary natural phenomenon."

As soon as the little emperor said this, the queen shook her head slightly.

"Your Majesty, even if you say that, there must be an internal connection between the operation of all things in heaven and earth, and the saint has clouds, which are formed in the sky and on the earth, just like a person who has a disease in him, and there will be symptoms outside him, so the doctor can prescribe the right medicine for the patient according to what he sees, hears, and asks, so that the medicine can be cured."

Yao Doudou never thought that the queen would have such an insight, and she didn't look like a pampered lady living in seclusion in the courtyard of the deep palace.

"Heavenly Maiden, there is some truth in what this palace said."

The queen looked at Yao Doudou expectantly, and Yao Doudou leaned over in agreement.

"Heavenly Maiden, I like to listen to you talk about some simple truths, it's better to do this, if you have time, you can also go to Taixue to teach and talk about reasoning, I think you are much more clever than those old-fashioned and rotten Confucians, let them also take a good look, how to tell boring things in an interesting and vivid way, in this way, not only can I learn a lot in Taixue, but even those students in Taixue must have benefited a lot."

The little emperor said and went to look at the binoculars again, while Yao Doudou smiled and replied with a promise.

When Yao Doudou came back from the Splendid Pavilion, the little emperor and the queen were still discussing astronomical knowledge with each other, thinking that Yao Doudou should have seen the results of helping the emperor and queen get closer, and Lixiang and Xingxiang thought that the queen would let them return to their side, but seeing that Yao Doudou was pleasing to the emperor and queen, and the queen looked up to Yao Doudou even more, so the two had to continue to stay by Yao Doudou's side.
