Chapter 906

This map has text marks, you can clearly see that this is a map near the imperial capital.

Seeing this, Zhao Fengnian could not help but admire the people who drew the map.

Such a small map, not only to clearly draw the outline, but also to mark on the text mark, how did he do it?

"How about it? See that? " , Ruixue looks at Zhao Fengnian for a long time and asks.

Hearing Du Ruixue's words, Zhao Fengnian just moved his eyes from the cylinder.

Staring at the cylinder in my hand, I didn't speak for a long time.

If Zhao Fengnian is surprised to be able to draw such a subtle map, the cylinder in his hand will surprise Zhao Fengnian.

This is indeed a magnifying glass. I mentioned it in my own book.

But no one has been interested in this aspect, Zhao Fengnian himself has been busy with other things, this matter forgotten.

I didn't expect to come back this time, but I saw the finished product. Moreover, the magnifier is composed of two lenses, which has the prototype of microscope.

Microscope, opened the human exploration of the micro world, so that human beings can better understand themselves and the composition of the world.

In addition, optical applications such as telescopes made by lenses enable human beings to see farther and more clearly without being limited to their own field of vision.

It can be said that in Zhao Fengnian's last life, the invention and application of lens laid the foundation of modern science.

"Who invented this little device?" Immediately, Zhao Fengnian asked what he thought.

"Well This was invented by Li Zhen, Li Shi's younger brother. He is now studying in Yongfeng Research Institute. He not only invented this, but also developed a device that can see far away, and has formed a production scale and has been equipped in the army... "

Ruixue for Yongfeng country can be said to know more than Zhao Fengnian, so a talk about this, Ruixue will be endless introduction.

"Oh, Li Zhen, is that child who used plaster to treat fever? How old is he now? Not ten, are you? " Listening to Ruixue's description, Zhao Fengnian asked in surprise.

Li Zhen, Li Shi's younger brother, Zhao Fengnian, remembers this little friend. When he saw him, he was still lying in bed, unconscious.

I remember at that time Li Zhen looked like only six or seven years old, very thin.

How can he now enter Yongfeng college to study, and also research out the application of lens?

Although the world's children mature relatively quickly, generally to 14 years old and Zhao Fengnian's last 18-year-old youth is almost old.

However, scientific research generally requires certain knowledge and experience. Li Shi is so young and should not have received systematic education before. How did he do it?

"Li Shi, is he eleven now? Shall I ask him to come and see you? " Although Ruixue is curious about why Zhao Fengnian has such a big reaction, it can be seen that Zhao Fengnian is very interested in Li Shi.

"Oh, no, when this is over, I'll go to the Research Institute in person. Please put away the beads first. I believe that one day we will go to see the location marked on the map by ourselves! " Hearing Ruixue's question, Zhao Fengnian shook his head.

Now Zhao Fengnian is really curious about the extent of scientific research in his territory during his time.

However, the high-level of the territory has not yet been restored, so I need to sit here and inspect other places.
