Spring goes and autumn comes.

Soon, at a glance, Chang'an City could be seen full of golden color.

This reminded Li Zhong of the ginkgo tree, and speaking of which, did he remember the dynasty wrongly.

That ginkgo should have been planted by Li Er himself.

"What is the teacher thinking?"

Li Chengqian watched Li Chong lift the curtain and look out the window, as if he didn't know what to think all the way.

Li Chong said: "In addition to the fact that the people are not very full, Chang'an City in this autumn is really beautiful." ”

Education is always inadvertent.

Li Chengqian is now slowly feeling some people's suffering.

Still, it's a volunteering as a teacher.

"You probably don't think so." Li Chong said again.

"That's because you have experienced less now, and when you experience more, you will find that it is really a beautiful thing to be able to calm down like this and look at this autumn scene."

After speaking, Li Chong also gestured and made a photo pose out of habit.

"If you're well fed, of course."

Of course, Li Chengqian could not understand it.

Because, aren't these all commonplace?

Even, the palace is even more beautiful than the one on the side of the road.

"If the teacher likes it, then go into the palace and see, the trees in the palace are taken care of, and they are better than this."

Li Chong had to keep an eye on Li Chengqian.

Finally, he said, "It's okay! It's been a long time since I've seen your queen mother. I don't know what happened to your queen mother. Bring Sun Simiao with you again. ”

In fact......

Li Chong just wanted to see Li Liqing.

I don't know what they've grown like now.

If he is disabled, he doesn't want it.

The carriage soon arrived at Sun Simiao's residence.

After getting out of the carriage, the servant of the family told Li Chong and Li Chengqian that there was a sick person temporarily, and his master had gone to see the patient, and then led the two to the main hall.

Li Chong asked Li Chengqian to take the convex lens, and after grinding it for a few months, the craftsman finally grinded out the convex lens.

Li looked at the quality again, and it was okay.

That is to say, if you want to see bacteria, this multiple may not be enough, but it is not a big problem to watch the moon at night and make a fire during the day or something.

Li Zhong thinks that this should be related to the curvature of the convex lens.

The more curved the arc, the greater the magnification possible.

But it is also more difficult to grind in this way.

But now when it is used as a telescope, the problem is still not big, and it is estimated that there should be at least twenty or thirty times more.

This thing, Li Chong just took it to Sun Simiao today.

Afterwards......

Li Chong should take it to Li Er.

After all, at this multiple, at most, it can only be used as a telescope, and it cannot be a microscope at all.

And soon, Sun Simiao also returned.

When I heard that Li Chong was coming, I was so happy.

"That's what you're talking about microscopes?"

"No, the technology is not up to par, and this can only be said to be a telescope at the moment."

"How do you use it?"

"Just put it in front of your eyes and look at it."

Seeing that things can be magnified in front of his eyes, Sun Simiao is also amazed by this object.

Seeing Sun Simiao's disciple coming back with a blood pressure monitor, Li Chong also asked, "Let you determine high blood pressure by taking the pulse, and you have studied it?" ”

Sun Simiao's disciple was also excited: "The teacher has been able to judge eight or nine by taking the pulse. ”

Sun Simiao glanced at his disciple with a rigorous attitude, and said: "Although the pulse can be roughly judged, it cannot be ruled out whether it is another disease, so even if it can be seen by taking the pulse, the old man still needs to use a blood pressure monitor to measure it, so that Fang feels that it is all right." ”

"It's just that this blood pressure monitor is often prone to breakage." Sun Simiao's disciple also said, "For example, the airbag is leaking or something." ”

Li Chong: "I can't help this, let the craftsmen think about how to improve it in the future." Tomorrow, I want you to come with me to the palace. ”

"What? Your Majesty is sick? Sun Simiao asked.

Li Chong: "It's not true, but I want you to show it to the queen." The queen gave birth to a prince two months ago, and her body may need to be recuperated, and she needs to give some advice on recuperation. ”

If it weren't for Li Chong's face, Sun Simiao might have written something to eat casually and sent it away.

"Okay, the old man will go with you tomorrow."

"Speaking of which, how is your Qianjin Fang writing?"

"It's still writing, and it's just getting started, how can it be so fast."

"In other words, is it possible to distribute some prescriptions that are often used to major states and counties, if the people are sick, they can go to the medicine themselves, although, the best words, it is natural to find a doctor first, and then prescribe the right prescription after hearing and asking, but sometimes, it is difficult to find a doctor in some places."

"It's admirable that Bachelor Li cares so much about the people."

"I'm just casually saying that if Doctor Sun thinks it's feasible, then I can ask Your Majesty to cooperate."

"These ordinary wind chills, you can really try them, and there are some bruises, burns and the like."

"Speaking of which...... If the sake can be purified and made into high-concentration alcohol, it can be disinfected and sterilized. This should also have a little effect on curing diseases and saving people. ”

"Then why don't you make it?"

Li Chong said: "The main reason is that I don't know how to configure the exact concentration of alcohol. And...... I kind of forgot what percentage of alcohol it was. ”

“……”

Sun Simiao was speechless.

"Then think about it."

"It's like 75 percent. If we use the method of elimination, 90 percent is definitely impossible, and 60 percent is certainly impossible, which is between 70 percent and 80 percent. Take the median value, 75 percent. ”

"Then now that you know, Master Li, you should go and match."

"There's one more problem to solve."

"What's the problem?"

"Ninety-nine percent alcohol, how much volume, how much water, is seventy-five percent?"

Sun Simiao smiled bitterly, "You ask the old man, who does the old man ask?" ”

"It is also said that there is a medicine that can be used to disinfect wounded soldiers and prevent abscess from becoming infected and deadly."

Sun Simiao simply stopped talking and let him continue.

"This stuff is better than alcohol, extracted from the garlic you eat."

"You forgot again?"

"Almost."

Sun Simiao couldn't cry or laugh.

"Therefore, this learning and learning, if you don't use it, it is a castle in the air, and only by the unity of knowledge and action can you really say that you have learned."

"What Mr. Li said is really good. It's like we practice medicine, it's useless to just read what is written in a book, you have to check the pulse yourself. ”

Sun Simiao's disciple also interjected with the same feelings.

Then Li Chong looked at Li Chengqian, "Why don't you ...... His Royal Highness the Crown Prince also studied medicine, and his skills are not pressuring anyway. ”

Sun Simiao hurriedly refused: "His Royal Highness the Crown Prince should learn how to govern the country well, this is the most important thing for today's Datang." ”

Sun Simiao: This is afraid of trouble.

But Li thought about it again, Li Chengqian may not really have that time. After all, if you study medicine, how can you succeed without ten or eight years.

He also gave up and said, "Okay." But I feel like I can at least learn about bruises, and bone correction or something. ”

Because Li Chong thought of his leg injury, some said it was diabetes, and some said that he fell on horseback, Li Chong also thought about it just in case.

Or do you want to learn it yourself?

After all, he was injured in a fall and couldn't do it himself.

Then Li Chong said: "I want to learn to be a bone." In fact, I have been fascinated by medicine for a long time. ”

This bone, you don't need to memorize the name of the medicinal herb, you can get it with two clicks, which is just right for a lazy person like him.

Sun Simiao saw that his interest was so high, of course, it was not easy to refuse.

But it is also a reminder: "This orthopedic is not easy to learn." If you want to complete the study, at least half a year. Of course, it also depends on talent. ”

"Is it so troublesome? Forget it, I won't study it. ”

Because if you think about it seriously, the prince's leg injury is definitely not as simple as a straight bone, maybe it is a comminuted fracture.

It's all shattered, and it's useless.

Li Chong had no choice but to look at Li Chengqian's legs again.

And then it was as if it was a very difficult decision.

"Forget it, let's learn, after all, if you can use it."

Well......

In fact, he prefers to do bone correction for women.

Maybe there's a chance in the future.
