"Okay, okay~! I won't say it, I won't say it, you two are innocent, head office, right?"

Li Zexuan was too lazy to pay attention to Yan Shaoning. He thought that this guy is really only based on his strength. What can he do?

"But when are you two going to get it? It will be dark in a while!"

But it was Li Zexuan who looked at the sky and couldn't help saying.

"Uh……"

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

Suddenly another ice cube was received, and Yan Shaoning almost jumped up because of the ice. This guy heard Mo Lingwei saying that he would not play today, so he hurriedly threw the two ice cubes in his hand, and then rubbed them so hard that they were about to freeze. hand.

Li Zexuan couldn't help but wonder: "What happened yesterday~? What happened to the two of you yesterday~? Let me hear it, maybe I can give you some help~!"

Mo Lingwei glanced at Li Zexuan suspiciously, and then said after thinking about it: "Shan Chief, let's talk about it first, I invented this thing, you just help me improve it, then you are not allowed to compete with me~!"

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

"Ehhh! Chief, don't go! I say I say it!"

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

"I... When I showed Xiao Ningzi the ice cubes to make a fire yesterday, I accidentally discovered that when two convex ice cubes are separated by a certain distance, you can see things in the distance through them, just like the clairvoyance in the novel. , very magical~!

It's a pity that Xiao Ningzi accidentally smashed the ice cube on the ground and shattered it. As a result... as a result, we can no longer recover the miraculous phenomenon before! We are just doing this experiment~! "

The more Li Zexuan listened, the more surprised he was, because according to Mo Lingwei, it was very likely that the two of them had accidentally created the telescope! He pinched his chin and thought about it:

"Miss Mo, the reason why you guys can't recover the miraculous phenomenon before is mainly 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 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 for the miraculous phenomenon of yesterday! In fact, Miss Mo, you have ignored one problem from beginning to end, and that is the ice cubes you used today. It's probably not the same as the ice cubes used yesterday!"

Mo Lingwei nodded, "Well, that's possible, after all, it's the first time I've made 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 had 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. I wonder if you understand the principle~?"

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

Mo Lingwei opened her mouth and said a little embarrassedly: "I saw this method from the handwriting of the Mo family's holy ancestor. It said that with this kind of convex ice cube, the sunlight can be turned into a small dot, and then That little spot was so hot it could ignite something."

Li Zexuan was stunned. He knew from Mo Huai's mouth that Mozi was very researched in geometric optics back then. He was able to image small holes. In contrast, concentrating light with a convex lens seemed like a pediatrician. Shaking his head, Li Zexuan said to Mo Lingwei and Yan Shaoning, who was listening with relish:

"You two come down with me, and I'll tell you how the legendary clairvoyant was made, and I'll give you a task by the way~!"

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

After Mo Lingwei and Yan Shaoning heard this, they were stunned for a moment, then surprised. They looked at each other and quickly followed.

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

"Hey! Chief, wait a minute!"

………………

After a while, Li Zexuan came to the fourth floor, then passed through the office area of ​​the twin towers in the center of the building, entered the teaching area, found a classroom at random, pushed the door open, and Mo Lingwei and Yan Shaoning had already followed.

Seeing that Li Zexuan wanted to give a lecture, the two found two seats in the first row and sat down. Mo Lingwei privately glanced at the neatly arranged tables and stools and the high podium in the classroom, and The smooth blackboard was a novelty in her heart.

"Miss Mo, let me first tell you the principle of making fire with 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 protrudes outward. Let's call this structure a convex lens..."

One classroom, two students, and one lecturer, the first class of Yanhuang Academy started quietly like this. However, no one could have imagined that such an inconspicuous class opened the prelude to the development of optics in ancient China. !

"Miss Mo, do you now understand the principle of concentrating light by a convex lens~?"

Li Zexuan never imagined that Mo Lingwei is such a person who asks the truth. You tell her that the convex lens has a converging effect on light, and she asks you why it can converge. Well, you can draw a light path diagram

Explain to her why a convex lens can converge light, and inevitably involves the refractive index of different media. As a result, she asked what is the refractive index and how did these refractive indices come from......

Therefore, this little common sense of physics ended up talking about two quarters of an hour. Thanks to his previous life, Li Zexuan's major contained a lot of optical components. His theoretical foundation is still solid. The little girl was overwhelmed!

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

"Well, I get it~! Chief, tell us about that clairvoyance!"

Mo Lingwei twitched her chin and smiled at Li Zexuan.

Yan Shaoning also nodded and said: "Well, I understand it too, Xiaoxuan, please continue!"

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

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