"Okay, okay~! I won't tell, I won't tell. You two are innocent, okay?"

Li Zexuan was too lazy to talk to Yan Shaoning. He thought to himself that this guy was really single based on his strength. What could he do?

"But when do you two plan to do this? It's going to be dark in a little while!"

But Li Zexuan looked at the sky and couldn't help but said.

"Well……"

Mo Lingwei looked up, then threw the ice cube in her hand to Yan Shaoning, muttering: "No more fun! No more fun! Let's talk about it tomorrow! It's really strange, the situation yesterday can't be replicated~! "

Suddenly receiving another ice cube, Yan Shaoning almost jumped up because of the ice. Hearing Mo Lingwei say that he would not play today, he quickly threw away the two ice cubes in his hand, and then rubbed them hard until they were about to freeze. hand.

Li Zexuan couldn't help but asked curiously: "What happened yesterday~? What situation did you two encounter yesterday~? Tell me and I will listen. Maybe I can give you some help~!"

Mo Lingwei glanced at Li Zexuan suspiciously, thought for a while and then said: "Chief, let's first say that I invented this thing, you are just helping me improve it, and you are not allowed to take credit from me~!"

Li Zexuan looked dumbfounded, "What credit can I take from you~? Hey, if you don't want to say it, forget it, I just have to go home and rest~!"

"Hey, hey! Chief, don't leave yet! I'll tell you, I'll tell you!"

Mo Lingwei became anxious, and the little girl quickly rushed in front of Li Zexuan to block the way, and then said:

"I... yesterday when I was demonstrating how to make fire with ice cubes to Xiao Ningzi, I accidentally discovered that when two convex ice cubes are separated by a certain distance, you can see things in the distance clearly through them, just like the clairvoyance in the storybook. Very magical~!

It's a pity that Xiao Ningzi accidentally dropped the ice cube and broke it on the ground. As a result... As a result, we will never be able to restore the magical phenomenon before! We were doing this experiment just now~! "

The more Li Zexuan listened, the more surprised he became, because according to Mo Lingwei, these two people might have accidentally created the telescope! He held his chin, thought for a while and said:

"Miss Mo, the reason why you can't restore the magical phenomenon before is actually because the distance between the two ice cubes is wrong!"

Mo Lingwei retorted: "Impossible! The distance between the two convex ice cubes yesterday is probably about the same as the distance we placed today?"

Li Zexuan explained with a smile: "Even if your distance today is exactly the same as yesterday, it is impossible to have the artifact phenomenon like yesterday! In fact, Miss Mo, you have ignored one issue from beginning to end, and that is the ice cubes you used today. The surface of the ice cube is probably not as convex as the ice cube I used yesterday!”

Mo Lingwei nodded, "Well, that's possible. After all, it's my first time to make this thing myself. How can I make it exactly the same every time? But even if it's different, what's the impact~? "

Li Zexuan smiled slightly, pointed to the ice mirror that was broken into several pieces on the ground, and said, "Of course it has an impact! Miss Mo, you used this ice cube to make fire yesterday. Do you understand the principle~?"

"I...I...of course...don't understand!"

Mo Lingwei opened her mouth and said with some embarrassment: "I saw this method from the notes of the ancestor of the Mo family. It said that using this convex ice cube, the sunlight can be turned into a small dot, and then That little spot is very hot and can ignite something."

Li Zexuan suddenly realized that he had roughly learned from Mo Huai that Mo Zi had done a lot of research on geometric optics back then, and he could produce images with small holes. In comparison, using convex lenses to focus light seemed childish. Shaking his head, Li Zexuan said to Mo Lingwei and Yan Shaoning, who was listening with interest:

"You two come down with me, and I will tell you how this legendary clairvoyance was made, and I will give you a task~!"

After saying that, regardless of whether they agreed or not, Li Zexuan turned around and went downstairs.

After Mo Lingwei and Yan Shaoning heard these words, they were stunned at first, and then they were surprised. They looked at each other and quickly followed.

"Hey! Xiaoxuan, you mean we can create clairvoyance?"

"Hey! Chief, please wait!"

……………………

After a while, Li Zexuan arrived on the fourth floor, then passed through the office area of ​​the twin towers in the center of the building and entered the teaching area. Then he found a classroom and pushed the door directly in. Mo Lingwei and Yan Shaoning had already followed.

Seeing that Li Zexuan seemed to want to give a lecture, the two of them found two seats in the first row and sat down. Mo Lingwei privately glanced at the neatly arranged tables and stools in the classroom, the high podium, and The smooth blackboard felt very novel in her heart.

"Miss Mo, let me first tell you the principle of making fire from ice cubes!"

Li Zexuan first drew a convex lens on the blackboard, then looked at Mo Lingwei and said, "The shape of this ice cube is convex. Let's call this structure a convex lens..."

In one classroom, two students, and one teacher, the first class at Yanhuang Academy unfolded quietly. No one could have imagined that such an inconspicuous class would open a new chapter in the development of optics in ancient China. !

"Miss Mo, do you now understand the principle of light gathering through convex lenses~?"

Li Zexuan never expected that Mo Lingwei would be such a inquisitive person. You told him that convex lenses can converge light, and she would ask you why it can converge. Well, you can draw a light path diagram to explain to her why convex lenses It can focus light, but it inevitably involves the issue of the refractive index of different media. As a result, she asked what the refractive index is and how these refractive indexes are obtained...

Therefore, this small piece of physics knowledge lasted for two quarters of an hour. Thanks to Li Zexuan's previous major, which had a lot of optical components, his theoretical foundation was quite solid. Otherwise, it would have been really possible for this little student to talk about it. The girl was stunned by the question!

But what is gratifying is that the two "students" Mo Lingwei and Yan Shaoning were very serious about listening to the class.

"Well, I understand~! Chief Shan, please continue to tell us about clairvoyance!"

Mo Lingwei twitched her chin and smiled at Li Zexuan.

Yan Shaoning also nodded and said, "Well, I understand, Xiaoxuan, please continue talking!"

Although Li Zexuan was an otaku in his previous life, it does not mean that his expressive ability is poor. On the contrary, in serious communication with others, his expressive ability has always been very good and his thinking is particularly clear. Perhaps it is because of this that he Mo Lingwei and Yan Shaoning could quickly follow his thoughts.

"Well, okay! Now that you understand this, the next step is very simple~!"

First update!

Thank you Gusheng_JUN for the 10,000 rewards!

I slept until nine o'clock. I originally planned to have lunch and then sleep in the afternoon, but I saw that someone was offering ten thousand yuan to remind me! Well, in this society, if you have money, you can really do whatever you want, so you won’t sleep in the afternoon!

emmmm...Xia Ke has a dream. He hopes that one day he can have Li Zexuan's hand speed and write more than a hundred chapters a day, shutting down all of you who rush for updates, and letting you catch up on updates every day and post book reviews continuously. There is no time to remind you!
