Ahem! Ink girl! Are you still busy? ”

After repeatedly promising Sun Simiao that the microscope would be delivered within a month, Li Zexuan came out of the other courtyard and wanted to go to another courtyard to find Mo Lingwei, but was told by the subordinates of the other courtyard that Mo Lingwei was in the workshop, Li Zexuan had to go down to Yunshan, came to the workshop, and found Mo Lingwei in a small room next to the steel factory.

"Mountain Chief~?"

Mo Lingwei raised her head, looked at Li Zexuan with a look of surprise, and said, "Mountain Chief, you can count it on!" In the past month or so, I have fully understood the principle of the generator! Now I'm asking the master of the workshop to try to build it! ”

"Oh~?"

Li Zexuan raised his eyebrows in surprise, and said happily: "Miss Mo is really a natural asset, she can eat through the generator so quickly!" Ahem! But don't worry about the generator, there is a more urgent thing that you need to do! ”

Mo Lingwei frowned slightly dissatisfied, she wasn't the kind of person who liked to give up halfway, "Mountain Chief, what could be more urgent than this generator?" According to my estimate, in more than half a month, I will be able to build a generator, can you delay your affairs a little longer? ”

Don't look at this girl who is usually fierce and arrogant in front of Yan Shaoning, but in the face of Li Zexuan, she is still quite restrained, in the final analysis, Li Zexuan is simply too perfect, knowledge and martial arts can be called the level of a grandmaster, the more you know about Li Zexuan, the more you will have a feeling of looking up to the mountains! So she still respects Li Zexuan, the head of the academy, after all, the master is the teacher!

Now if Yan Shaoning said these words, it would be strange if Mo Lingwei didn't blow up!

"More than half a month! Miss Mo seems to be very confident~! ”

Li Zexuan smiled slightly and said, "But within half a month, the dam will not be built, and even if the generator is built, I am afraid it will be useless~!" And my matter is not difficult for Miss Mo, it is estimated that it will be completed in less than half a month~! ”

When Mo Lingwei heard this, she thought about it with her eyebrows, and finally nodded: "Okay then!" What the hell are you talking about~? ”

Li Zexuan said: "Miss Mo, the academy is about to set up a medical school, I plan to ask you to build a microscope for the medical school, the previous astronomical telescope was to see the stars thousands of miles away, and this microscope is to see the tiny objects around us that cannot be seen by the naked eye, or living things!" ”

Mo Lingweiqi said: "Mountain Chief, isn't this what you said just a magnifying glass?" I've already made one for Master Liu before! Besides, what little things can't be seen with your eyes? ”

Li Zexuan was helpless, the textbooks in the academy included mathematics, physics, chemistry, and geography, but there were no organisms, so not only Mo Lingwei didn't know the concept of bacteria, but all the teachers and students in the academy didn't know.

The reason why he did not include biology in the teaching subject of the college was because of his considerations.

The most basic theoretical basis of biology is the theory of evolution, if he writes in the book that human beings evolved from monkeys, he will not cause an uproar, and Li Er, who claims to be the son of the real dragon, will spare him? How could the descendants of Yan Huang in the world spare him?

Darwin's theory of evolution was put forward in the nineteenth century, when the power of the church was greatly weakened, and the scientific system of Western countries had been formed, and the trend of inclusive thought had been abused, and there was a great tolerance for a hypothesis, of course, the most important thing is that Darwin's theory of evolution really could not find any remarks attacking God, so the church believed that Darwin did not oppose God.

In today's Tang Dynasty, the wisdom of the people has not yet been opened, and everyone still believes in the myth that human beings were created by Nuwa, which is really inopportune to put forward the theory of evolution! Therefore, when Li Zexuan founded Yanhuang Academy, he directly banned the course of biology completely!

Of course, there must be many unreasonable things in this way, which is not conducive to the development of medicine, and he may launch a deleted version of the "Biology" textbook later, but that's all for later!

"Ink girl! A microscope is not the same as a magnifying glass, it has a higher magnification than a magnifying glass and sees things more clearly! As for what is invisible to the naked eye, Miss Mo, have you ever seen rotten meat? ”

Li Zexuan pondered for a moment and said with a smile.

Mo Lingwei was a little confused, she was stunned, and replied, "Of course I've seen carrion, Mountain Chief, what are you saying this for?" ”

Li Zexuan said with a smile: "This meat has been left for a long time, and the reason why it will rot is actually because in the air we breathe, there is a very small, very small, small bug, some of these little bugs will eat meat, and they can digest the meat, so after a long time, the meat will completely rot!" ”

When Mo Lingwei heard this, her face suddenly became frightened, she hurriedly covered her nose, her eyes widened, and said, "Mountain... Mountain Chief, that... Wouldn't that be able to get into our bodies through our mouths and noses! It's over, I'm about to turn into a pile of carrion! I'm still young, I don't want to die yet! ”

At the end, a trace of crying could be heard in this girl's voice!

Li Zexuan rolled his eyes helplessly, and said with some tears and laughter: "Ahem!" Ink girl, although it is true that some small insects can enter the human body through the air, there are many things in our bodies that can kill small insects, so only the body of the dead will rot, and the living will not! Miss Mo, don't worry about it anymore! ”

Mo Lingwei blinked, then put down the slender jade hand covering her mouth and nose, and after holding it for a while, this girl's face turned red, she quickly gasped a few times, and said slightly angrily: "Whew~!" Scared the hell out of me! Chief, why don't you say it all? I thought I was going to rot! ”

Li Zexuan was speechless, and said in his heart that you have a lot of drama by yourself, is it possible to blame me?

"Okay, Miss Mo, let's get down to business, I'll tell you about the composition of the microscope~!"

Li Zexuan coughed lightly, and then saw that there was chalk in this room, and there was a small blackboard, he walked to the blackboard and picked up the chalk, and began to talk while drawing: "The simplest microscope is actually a convex lens, but this convex lens is a little special, its curvature is very large, the focal length is very short, and the magnification is much larger than the general convex lens.

What I'm talking to Miss Mo about today is not this kind of single-convex lens-type magnifying glass, but it is composed of two convex lenses, one with a long focal length called an objective lens, and one with a short focal length called an eyepiece. The light reflected by the object is first imaged through the objective lens, and the object should be between one and two times the focal length of the objective lens to form an enlarged inverted real image, and then the first image of the object is used as the "object" for the second imaging ....... through the eyepiece"
