Li Xiaoyue was very happy and went home to start assembling the microscope.

Some parts are made of cast iron, and then polished smooth to meet her required size.

The craftsmanship of the blacksmith Wang has also been practiced now, as long as Li Xiaoyue asks for it, he can basically make it.

Now start installing the lenses and keep commissioning.

With the lenses that are currently grinding out by Wang craftsmen, they can be magnified up to 20 times, which is amazing!

Li Xiaoyue was holding a green onion skin at this time, watching over there.

Li Changan came back from outside and greeted his mother, "Mother, how are you today?" ”

Li Xiaoyue didn't look up, she was looking at her hair, "It's good today, I have something here, specially made for you, come and take a look!" ”

Li Changan was slightly stunned, his face puzzled, "What's so beautiful about hair?" ”

Hearing this, Li Xiaoyue raised her eyebrows, "You will know it when you see it!" You close one eye and look with the other. ”

Seeing this, Li Changan walked over and looked carefully according to what his mother said.

I was shocked by this look, it's just a hair, why is it so thick?

When his eyes moved away from the microscope and turned his head sideways, Li Changan saw that the hair was still a thin one, and returned to the microscope.

"It's amazing, it's amazing!" Li Changan looked surprised, "Mother, how could you have thought of getting this thing?" ”

Li Xiaoyue smiled, "Last time, I heard you keep talking about what is in the dirty stuff, which will make the wound seriously inflamed and accelerate the ulceration. ”

"When we disinfect it with high wine, we must have killed something, protected the wound, and didn't let it invade the wound to stop the inflammation."

Hearing this, Li Changan nodded again and again, "Yes, Master and I are very curious, but our eyes can't see it." ”

"This thing can magnify things a lot, maybe you can see it."

Li Xiaoyue nodded, "Yes, this lens is not perfectly handled now. ”

"If you change the thickness of the lens and some parameters, you can enlarge it by 10 times, 100 times or even 1,000 times."

"When it's big enough, even the smallest things can be seen. Isn't it, Chang'an? ”

Li Changan nodded again and again when he heard this, "Mother, you are really too smart." I really didn't expect you to take all the words I said casually to heart. ”

"Not only that, but you put it into action, and you used your ingenuity to make this thing. It is my greatest luck to have a conscience like yours. ”

Li Xiaoyue was praised with a smile on her face, "Actually, it's not that good, let's call this thing a microscope." ”

Li Changan nodded, "This name is very good, this is really good news, I want to tell the master!" ”

After speaking, Li Changan ran out happily.

Doctor Liu is summarizing his experience into a booklet and passing it on to his apprentices.

"Master, I have good news here!" Before Li Changan entered the door, he began to speak loudly.

Doctor Liu hurriedly put down the brush in his hand, it must be a great thing to make the always calm apprentice so elated.

Since Liu Yunde returned to Lihua Village, Li Changan's smile has become less and his personality has become more boring.

Except for studying medicine with a stuffy head, I am not in the mood for anything else.

"What's so much fun?" Doctor Liu asked with a smile, he had no children, and he had already regarded Li Changan, an apprentice, as his own child.

This may also be the last apprentice in his life, so he teaches very carefully.

Li Changan tugged on the sleeve of the master's coat and walked out, "Master, hurry up." My mother has made good things again, and I think it is very useful for improving our medical skills. ”

Doctor Liu was puzzled, in addition to high alcohol, what good things did Mrs. Li come up with?

It is good for improving their medical skills, and Doctor Liu is very curious.

The master and apprentice came to Li Xiaoyue's study, and Li Changan couldn't wait to show the master the microscope.

"Master, it's my mother's microscope that magnifies very small things. Look at this hair! ”

Doctor Liu's eyes showed curiosity and leaned over to look, "Ah! It's so big! ”

"Master, if you can magnify enough multiples, you will definitely be able to see smaller substances."

"We've been puzzled, why does a dirty wound accelerate inflammation and suppuration?"

"We've always wondered what's in the dirt, what's in that pus?"

"If we can see them, won't we be able to find more things to kill them and better treat their wounds later."

Doctor Liu thought so, "Your idea is very good! Mrs. Li, is there a way to expand the multiple? ”

Li Xiaoyue nodded, "Of course you can, but you need to sharpen better lenses." ”

"I'm going to collect more transparent water jade, or there will be too many impurities, don't interfere with your vision."

Hearing this, Doctor Liu thought for a while, "Although there are no lenses that are bright enough, the existing lenses are fine." Although there will be impurities, we will discern them ourselves. ”

"The most important thing now is to make a microscope with a larger multiplier first, Mrs. Li is tired!"

Li Xiaoyue nodded, "Okay, I'm having people sharpen the lenses now, and when it's done, I'll call you over." ”

Doctor Liu touched the microscope with his hand, couldn't put it down, and really wanted to move away now.

After all, this is Mrs. Li's study, and it is not suitable for him to stay here as a foreign man.

Seeing what Divine Doctor Liu meant, Li Xiaoyue smiled, "Divine Doctor Liu, don't worry!" When I adjust it, reduce the error, and then calculate the correct multiple, I'll give it to you. ”

"After all, it's the first time I've done it, and there are a lot of things that need to be improved."

Hearing Li Xiaoyue say this, Doctor Liu smiled, "That's okay, I'll wait for Mrs. Li to adjust it here." Only by constantly changing can we continue to improve. ”

"It just so happens that I'm also very busy these days, and I want to write down my experience over the years and some effective recipes, and pass them on to Chang'an in the future."

Hearing this, Li Xiaoyue's eyes lit up, and she thought of something that would benefit the country and the people.

Typography.

Doctor Liu's medical books were printed and passed down.

Engraving printing is more wasteful, and movable type printing is more economical.

However, she only knew the principles of movable type printing, and did not know how to fire movable type and some related materials.

It seems that she will have to spend more money and find someone to study for her.

As long as there is silver, there are people who are willing to research and develop.

Just like the two craftsmen and apprentices of Wang, they have made great progress now and have been able to complete the task according to her requirements.

Li Xiaoyue didn't expect it, but when she thought of it, she got all the useful things in her memory.

Even if it is rough at the beginning, there will be more smart and powerful people in the future, and the research and development will be passed on to benefit more people.

Li Xiaoyue knew that it was more valuable to do this, and it was not in vain for her to come here.

Even in the book, she wants to make her life more fulfilling and meaningful.
