Oh, the Heavenly Maiden also knows Mr. Meng Qiuhe. ”

The woman said with interest, and Yao Doudou smiled awkwardly.

The woman wanted to inquire further about the matter between Yao Doudou and Mr. Meng, but the other superintendents of the college also entered the academy one after another.

"Yo, isn't this a heavenly maiden, it's really disrespectful."

A sturdy superintendent with a tiger's back stepped in between Mr. Meng and the woman, and saluted Yao Doudou with a fist, Yao Doudou just nodded in salute because he was barefoot.

"The Heavenly Maiden is young, and she can come to this Tianzi No. 1 school to give a lecture, but there is really no one before or after. By the way, I forgot to introduce myself to the Heavenly Maiden, my name is Fan Bichi, and I am the archery teacher of the Tai Academy, if the Heavenly Maiden has time, she can come to the Tai Academy, and the contemptible people can personally teach the Heavenly Maiden to ride horses and archery. ”

As soon as Mr. Fan's words fell, Mr. Meng drove Mr. Fan aside with a goose feather fan.

"Mr. Fan, Your Majesty is about to arrive, you still don't disturb the Heavenly Maiden preparing to give a lecture."

After Mr. Meng finished speaking, Mr. Fan nodded again and again.

After the six superintendents of Tai Academy were ranked one after another, the woman led by her fist saluted Yao Doudou.

"Heavenly Maiden Niangniang, named Ma Yan, is the superintendent of poetry and music in Tai Academy, so I will introduce you to the other five superintendents of this academy."

"This is Mr. Meng Qiuhe, the superintendent of the book school."

After Ma Yan finished speaking, Meng Qiuhe hugged the fan and arched his hand slightly to Yao Doudou.

"This is Mr. Zhu Qinggui, the superintendent of the Imperial School."

After Ma Yan finished speaking, a middle-aged man dressed in green clothes and with a strong bookish atmosphere smiled and bowed to Yao Doudou.

"This is Mr. Luo, the superintendent of Yi Math."

After Ma Yan finished speaking, a middle-aged man wearing a square scarf and dressed in simple clothes also bowed to Yao Doudou.

"This is the Spring and Autumn Archery Superintendent Fan...... Mr. Bichi. ”

When Ma Yan said this, her face showed a trace of disgust, and Mr. Fan gave up his hand again and again, showing a look of admiration for Yao Doudou.

After Ma Yan finished introducing, Yao Doudou also sat at the table and nodded to the superintendents.

"Your Majesty has arrived."

As Gonggong Gao shouted outside the school, the superintendents walked out of the school hall and knelt down to greet him, and Yao Doudou took advantage of this opportunity to quickly put on his shoes.

Just when Yao Doudou also wanted to walk out of the school and kneel to greet the little emperor, he didn't want to collide with the little emperor, if it wasn't for Dr. Ma to quickly support the little emperor, the little emperor would probably have to fall around.

"Your Majesty, Your Minister......"

Yao Doudou wanted to kneel down to apologize to the little emperor and admit his mistake, but was quickly helped up by the little emperor.

"Heavenly Maiden doesn't need to mind, it's because I admire the knowledge of the Heavenly Maiden and want to listen to you talk about some esoteric things as soon as possible, so I'm in a hurry, you better prepare and start talking immediately."

As he spoke, the little emperor walked into the hall and sat down in a position in the center, while Dr. Ma led a group of superintendents to stand behind the little emperor and listen.

Lixiang and Xingxiang looked at the door of the school, Yao Doudou also stood in front of the table, looking at eight pairs of eyes looking at her, Yao Doudou's heart was also inexplicably nervous, although she often went to the university to give lectures in modern times, but in the face of a group of knowledgeable ancients, to tell some knowledge that they can accept and agree with, I am afraid it will take some thought and effort.

"Ahem, thanks to Your Majesty's refusal to give up, invited the minister to give a lecture in this Tai Academy, and Dr. Ma and a group of superintendents raised love, willing to listen to Xinyue's lectures, Xinyue is honored to be, very grateful, Xinyue sees that the professors in the Tai Academy are Confucian classics of the Six Classics and Six Arts, Xinyue does not dare to use this in front of you to get an axe, so Xinyue will talk about some superficial knowledge, and I hope you will teach and criticize."

Yao Doudou said this, and bowed his hand to everyone, but everyone didn't say a word.

Due to nervousness, Yao Doudou suddenly couldn't remember a word of the content she had prepared before, she only felt a blank in her mind, and then Yao Doudou talked a lot of content, and she didn't know whether these contents could be accepted by everyone, and everyone frowned and didn't say a word about what Yao Doudou said, and the little emperor also widened his eyes and couldn't understand it at all.

Because the little emperor didn't shout to stop, so Yao Doudou said for more than two hours, and she still drew on the wooden board behind her after some intelligible explanations, Dr. Ma and the school monitors listened to Yao Doudou's intense point, and also stretched out their hands, seemingly to applaud, but it didn't seem to be applauding.

"Therefore, when a person's speech nerve is traumatized, she cannot speak even if her vocal organs are normal."

After Yao Doudou finished speaking, he wiped off the diagram on the wooden board, and everyone and the little emperor nodded slightly.

"Okay, that's all for today's content, I think everyone is also a little tired, and if you haven't finished speaking, we'll ...... next time."

Yao Doudou stopped halfway through speaking, thinking that she would not be tired to death if she said this, forget it this time, and mention what next time.

"Okay, guys, that's it, I don't know if you have any other questions to ask, if not, then we will ...... today"

Yao Doudou thought about finishing the endding quickly, and then everyone had no doubts, and went straight to class, but the little emperor was still unsatisfied with what Yao Doudou said, although it was late at night, and the candles in the school were about to burn out.

"I have a little question I want to ask the Heavenly Maiden."

The little emperor cautiously raised his hand, and Yao Doudou nodded with a smile.

"Heavenly Maiden, you just said that there is a kind of thing called a movie, that is, you can draw every move of a person, and then broadcast it completely, is there really such a thing in this world?"

Regarding the little emperor's suspicion, Dr. Ma and the superintendents also found it incredible.

Yao Doudou pondered for a moment, and then nodded slightly to the little emperor.

"Yes, Your Majesty, in fact, the principle is very simple."

Yao Doudou said and picked up the paper and pen on the table and made a rectangular paper tube.

"Your Majesty, you see, there is a small hole in the top of this paper tube, and when the candle flame of the opposite candle is projected on the paper wall of the paper tube through the small hole, an inverted shadow will be formed."

Yao Doudou pointed the paper tube at the candle, and the little emperor and the superintendents also came over, and sure enough, the candle flame of an inverted candle appeared on the paper wall.

When everyone saw this magical scene, they couldn't help but be amazed.

"Therefore, if we can make a special kind of paper, so that the hole can be completely rubbed on this paper at the moment of opening, then it can permanently record the most real moment in our lives."

Yao Doudou said this, and everyone nodded slightly.

"And if we completely bring all these moments together, it will become a coherent picture of the film, that is, the film that the minister just talked about."

Yao Doudou said as he took out another book from the table, and then drew a small windmill on each page.
