Otaku Engineer in Great Tang Dynasty Chapter 888: Engineering, new world! (Next)

"Mo Zhong, come here!"

Li Zexuan, who was about to play a new game, didn't take any immediate action. Instead, he evoked the stunned Mo Zhong next to him.

"Here!"

Mo Zhong quickly recovered from his shock, ran to Li Zexuan's side, arched his waist, and made a sound of hearing.

I saw Li Zexuan approach Mo Zhong's ear, whisper something, and then...

"Huh? Shan Chang! This...you didn't kid me, did you?"

Mo Zhong glared, and he could lay an egg with his mouth open.

"Who has the time to joke with you? Hurry up!"

Li Zexuan has no good spirits.

Everyone in the field was a little dazed when they saw this. They didn't know what Li Zexuan had ordered, and it would make Mo Zhong show this expression.

However, their doubts did not last long. After Mo Zhong ran out, after about half a cup of tea, everyone noticed the abnormality and suddenly shouted!

Because Mo Zhong actually ran to the roof to uncover the tiles!

There is a saying that goes well. If you don’t fight for three days and you go to the house to reveal the tiles, the teachers and students off the field can’t help but say in their hearts: Mo Zhong’s madness? Dare to run to the roof to uncover the tiles?

"Shanchang, do you think you can remove this piece?"

Mo Zhong on the roof squatted down and shouted.

"Om~!"

The students and teachers in the auditorium realized that Li Zexuan had just instructed Mo Zhong to go to the house to reveal the tiles! They couldn't understand what Li Zexuan's move meant, and they couldn't help but talk a lot.

"No way! A little further behind!"

Li Zexuan glanced sideways, then replied.

The ink clock on the roof had to cover the uncovered tiles, and then lifted another one, and asked: "Mountain Chang, is it all right?"

"Sure!"

"Then...then I will go down!"

"Stay on top for a while, I need you later!"

The bizarre conversation between these two people shocked everyone's attention. Fortunately, after saying this, Li Zexuan finally became "normal". He found out from a box on the desk I took a bright triangular glass, and said to everyone off the court:

"Does anyone know the color of sunlight?"

(About optics, the first book of "Physics" in the academy did not mention it)

"Does this need to be asked? The sunlight must be white!"

As soon as the voice fell, Cheng Chumo couldn't help laughing.

"It is obviously red! The sun is so red in the morning, how can it be white?"

Another student immediately retorted.

"What is red? It's obviously yellow, can't you tell the difference between red and yellow?"

After a while, there was a commotion off the court. Li Zexuan coughed slightly and said, "Okay, it's all quiet! No need to fight, then I will let you see what color the sun is. !"

The students calmed down immediately and looked towards the podium with their breath held intently!

Li Zexuan first set up a stand on the podium, with white paper pasted between the stands (as a white screen), and then he used the triangular glass side to face the sunlight (at this time everyone understands that the ink clock ran to the roof What is the purpose of uncovering the tiles? It turned out to be to bring in the sun), a magical scene appeared!

"Okay, do you see anything?"

Li Zexuan pointed at the white screen on the podium and smiled.

"Wow~!"

The teachers and students were in an uproar. They actually saw a colorful spot on the white paper. Isn't this a rainbow?

"Rainbow? It didn't rain, where did the rainbow come from?"

"Yeah! Is it still sunny today?"

"A miracle! Can a mountain leader create a rainbow?"

"No! The head of the mountain should tell us that the sun is seven colors!"

"How is it possible? Why is the sunlight I see white?"

"What is white? Obviously yellow!"

"Red!"

The students were amazed for a while, and some of them started arguing again. Li Zexuan said: "It's all quiet! Through this little game, I just want to tell you that many times what you see with your own eyes may not be true. Yes! For example, sunlight, some of you think it is white, red, yellow, or transparent, but in reality? It is composed of seven colors mixed together!

For another example, have you ever thought about what kind of substance light is? Is it as vague as the sound, or is it a real substance like the rice and flour we eat? "

When everyone heard it, they fell into deep thought.

After a long while, a thinner and young-looking student stood up and asked, "Student Li Yan, ask the head of the mountain, what is light?"

Li Yan, this is Li Chunfeng's son!

Li Zexuan's heart moved. He had seen Li Yan on the entrance examination report card and knew that this kid was Li Chunfeng's son, but this was the first time he saw Li Yan.

Just.....

"Hehe! This is a good question! But let's put this question aside, and then I will show you a little game!"

It was Li Zexuan who gave another fascinating smile, and then said "basely".

Li Yan: "￣へ￣......"

Even as a Taoist, Li Yan, who has cultivated his character for many years and has been quiet and inactive, he couldn't help jumping at this moment. He opened his mouth and thought... He wanted to explode a few swear words, but think about it. Sit back.

Even if he is like that, let alone the rest of the students!

"Mountain long, please tell us clearly first!"

"That's right! Make it clear before playing the game!"

"Cao, do it again! You know how to play games! Be your sister's game!" (This is sister Wang Litai whispering indignantly in private)

Li Zexuan's face was stern, he pressed his hand down, and said, "It's all quiet! I'm not afraid of late for a good meal. I am anxious to eat hot tofu. What are you anxious? Show me carefully and study carefully!"

Seeing Li Zexuan's tendency to go crazy, the students shut their mouths very wisely.

"Mo Yun, bring this thing to Mo Zhong!"

Li Zexuan took out a wooden board (there is a small hole in the wooden board), handed it to Mo Yun, and ordered.

Afterwards, he instructed the students to close all the curtains (the auditorium has glass windows). At this time, Mo Yun had already brought the wooden board to the roof and handed it to Mo Zhong.

"Mo Bell~IndoMTL.com~Use a wooden board to cover the hole in the roof!"

Li Zexuan ordered again.

Mo Zhong did what he said, and immediately the entire auditorium plunged into darkness. Only Li Zexuan had a very thin beam of light that looked particularly conspicuous.

Immediately afterwards, everyone heard Li Zexuan say: "I am holding a piece of paper in my hand. There are two very close slits on the paper. I will put this slit under the beam for a while. What is happening!"

The students and teachers are all wondering: What can happen? Isn't it just that one beam of light becomes two beams?

However, reality slapped everyone in the face once and again, and saw a bright and dark streak appear on the white screen in the dark, with more than two bright streaks! But everyone clearly saw the paper Li Zexuan was holding up, and only two beams of light were separated! Why do so many stripes appear below?
