"What's the matter, Heavenly Maiden, are you uncomfortable somewhere? I still have a lot of things to ask you for. ”

After the little emperor finished speaking, Yao Doudou smiled awkwardly.

"Come, give the goddess a seat."

For the little emperor's affection, Lord Shangguan and Pei Shaoling were very surprised, even though the status of the Heavenly Maiden was noble, but she had not yet made any contribution to the country's society, and Lord Shangguan and Pei Shaoling had never received such an honor.

A eunuch brought an embroidery stool to Yao Doudou, Yao Doudou was also standing a little numb, so he sat on it, and the little emperor saw Yao Doudou sitting down steadily, and a happy smile appeared on his face.

"Your Majesty, the two doctors from the Taishi Bureau are still waiting outside the court, isn't it time to invite them in."

The chief eunuch standing beside the little emperor whispered to the little emperor, and the little emperor's brows instantly condensed again, these two doctors were deliberately found by the little emperor to make things difficult for Yao Doudou, but when the little emperor saw that Yao Doudou was so beautiful and refined, he instantly regretted the attention he had made before.

"This ......"

The chief eunuch saw that the little emperor was a little undecided, so he made a slight gesture to the little emperor.

"If it is inconvenient for Your Majesty, then the slave will ask the two of them to go back first."

As soon as the chief eunuch's voice fell, the little emperor said no need.

"Let's invite them in."

After the little emperor finished speaking, the chief eunuch turned around and glanced at the little eunuch beside him, but Lord Shangguan expressed his incomprehension of the little emperor's actions.

"Your Majesty, what are you?"

The little emperor glanced at Lord Shangguan, then at Yao Doudou, and then smiled slightly.

"The teacher and the Heavenly Maiden don't have to be nervous, I just want to take the opportunity of the Heavenly Maiden entering the palace to let two doctors from the Taishi Bureau come to accompany me, one is to discuss some astronomical and geographical knowledge, and the other is to ask the Heavenly Maiden for some strategies for governing the country."

After the little emperor finished speaking, Lord Shangguan stroked his beard and nodded slightly, while Yao Doudou smiled awkwardly, Yao Doudou thought, in addition to eating, drinking, and having fun, I also operate on people, how do I know how to govern the country, this little emperor specially found two doctors to come over, it won't be to make fun of me.

Without waiting for Yao Doudou to think about it, two old men with long beards and white hair dressed in dark official uniforms entered the pavilion and gave the little emperor the courtesy.

"Ahem, Dr. Wang, Dr. Zhao, don't you have any questions to ask the Heavenly Maiden, now that the Heavenly Maiden is here, if you have something to say, please ask."

When the little emperor said this, the two white-haired old men bowed to the little emperor and the heavenly maiden, and the fatter Dr. Wang first asked Yao Doudou questions.

"Heavenly Maiden, Lao Chen has worked in the Taishi Bureau for nearly forty years, although he is not familiar with the astronomical calendar, but he also has a little experience, but there has always been a doubt in Lao Chen's heart, and I hope that the Heavenly Maiden can show it."

After Dr. Wang finished speaking, Yao Doudou nodded slightly, signaling that Dr. Wang had something to say, but it didn't hurt to say it.

"As we all know, wind, rain, thunder and lightning are all natural imaginations, transformed by the turbid air of heaven and earth, and the sky is high and clear, a layer of unstained, it should be an ethereal void, why there are meteorites falling in this void, and I hope that the heavenly maiden can explain her doubts to the old minister."

Dr. Wang said and arched his hand slightly to Yao Doudou, but the other people present heard this question, but they were confused, even Lord Shangguan, who was the teacher of the little emperor, had never heard of this question, Lord Shangguan looked at Dr. Wang, and Dr. Wang put on a scheming look.

Yao Doudou smiled awkwardly, if you use the modern astronomical cosmology, this is just a question that even a child can answer, but she is now in the Shuyun Kingdom more than a thousand years ago, if she uses modern astronomical knowledge to explain, it is obviously not convincing to everyone, Yao Doudou pondered for a long time, and then slowly stood up.

"Dr. Wang, please forgive the people for saying that this Outer Heaven Stone is not naturally generated from the sky, but from ...... Coming from the Taixu Immortal Realm, the Taixu Immortal Realm not only has immortal pavilions, flowers and trees, but also landscapes and stone insects, light and color miracles, and this meteorite outside the sky is a stone that fell inadvertently from the Taixu Immortal Realm......"

Before Yao Doudou finished speaking, Dr. Wang directly slapped his face.

"Heavenly Maiden, you won't be joking with the old man, there are sun, moon and stars beyond the earth, why come to the Void Immortal Realm, please think about it carefully, don't answer randomly."

After Dr. Wang finished speaking, Yao Doudou was silent for a long time, obviously this Dr. Wang also has a certain understanding and attainment of the universe, and he can't just fool around.

Lord Shangguan saw that Yao Doudou had a male face, so he smiled slightly.

"Don't be nervous, although the old man has not studied astronomy in depth, but the sun, moon and stars in the sky have certain operating laws, if you want to answer Dr. Wang's question, you have to start with the five stars of gold, wood, water, fire and earth."

In response to Lord Shangguan's prompt, Yao Doudou reorganized the logic and language.

"Ahem, just now the folk girl was indeed joking with Dr. Wang, the Taixu Immortal Realm does exist, but it exists in places where mortals can't reach it, just now Lord Shangguan talked about the five stars of gold, wood, water, fire and earth, in fact, these five stars have a similar structure to the earth we are in, maybe what I am talking about next will break your perception of astronomical knowledge, but this is indeed the truth, the reason why I am joking with you is that I am afraid that you will not understand the truth of what is said, and then think that I am talking nonsense."

Yao Doudou smiled awkwardly, and Dr. Wang and Dr. Zhao looked at Yao Doudou with disdain, thinking that this is just a little girl with a yellow heart, and look at how much sophistry you can have.

"In fact, according to the people's understanding of astronomical knowledge, the world we are in is actually a spherical shape, and the reason why there is a change of day and night is because this spherical shape is still rotating, and this spherical shape is rotating around the sun, so there is a change of seasons."

As soon as Yao Doudou said this, everyone was confused.

"Nonsense, since ancient times, as we all know, the sky is round like a canopy, the place is like a chess game, the earth is obviously flat, if it is true that we live on a round ball, then the person under the ball will not fall back to the sky."

Dr. Zhao, who was standing next to Dr. Wang, finally happened, but what he said was not good.

"Dr. Zhao, the reason why you think so is because you don't realize that there is actually a thing called gravity in this world, haven't you ever thought that whatever water flows low, everything thrown will eventually fall to the ground, and it is precisely because of such a characteristic that we live on the spherical earth so that it will not fall to the sky."
