"Lord, the old man has carefully studied your books, and I have to say that the lord of the country seems to have broken through the slightest opportunity, which makes the old man doubt whether you are the star of the earth!"

"I can't afford your old fallacious! You're okay to stop me, don't you just want to compliment me? There is something that I don't need to worry about. Pen Fun Pavilion www.biquge.info"

The two looked at each other and smiled, and said, "There is really something to trouble the lord of the country, I know that you are busy, just take the time to give us a lecture." After speaking, the two of them told Li Yang in detail.

Many of the people in this school are descendants of witch doctors, and many of the tribes on the island of Ryukyu are also the leaders of the tribes, because in this miasma-ridden place, the fight against terrible diseases has always been a job that has been carried out from birth to death. These students have their own unique plot for medicine.

In order to change the backward status quo on Ryukyu Island, Li Yang also sent some doctors to the island to practice medicine, at this time some other disciplines on the Ryukyu Island are very unified is the Li Yang school, only medicine is the vein of witch doctors and Chinese medicine, sometimes integrated with each other, sometimes poured into each other, but overall Chinese medicine is better, but in the treatment of tropical diseases, Chinese medicine is sometimes not more effective than experienced witch doctors.

Finally, Li Yang, who was looking forward to the stars and the moon, regarded him as a living encyclopedia, and naturally would not let him go.

It is rare that there are still so many people who are interested in medicine on the Ryukyu Island, unlike the Central Plains doctors, whose status is not high, which also leads to many treasures of Chinese medicine that have not been handed down, but are later called pseudoscience.

But Li Yang really doesn't know anything about Chinese medicine, but as a person with basic biological knowledge, how interesting would it be if he introduced some knowledge of Western medicine into the witch doctor and Chinese medicine?

Thinking of this, Li Yang happily agreed to the request of the two, and there was no need to wait until tomorrow, just start talking now.

Old Master Hou is nothing, Wang Er is excited, after all, he is a crippled person, and he always has the most naïve illusions about medicine.

Soon a classroom was full of people, not only interested students, doctors in the school, but also some teachers came to have fun.

There are three people next to the podium holding charcoal or brushes, ready to record Li Yang's every word, which will be another textbook.

"Well, people and kittens and dogs outside are essentially the same, they are all composed of the five elements of gold, wood, water, fire and earth." Li Yang still decided not to introduce too esoteric concepts, and in some places still used familiar things.

"Even if you haven't studied the structure of animals, you should have killed chickens, ducks or other animals, so I'll compare the five internal organs of people, the heart, and fire, which is the source of power for us to move, I call it blood circulation, and blood transports energy to all parts of the body."

"The liver and gallbladder belong to wood, which is a sewage pool for detoxification and detoxification, and it is also a small storehouse for storing blood, and it is also very useful."

"The lungs belong to gold, the organ that we breathe the spiritual energy of heaven and earth, without him, the nourishing qi in the sky cannot be used by me, and without the nourishing qi, people will die. As for Qi cultivation, I'll find a way to catch some for you next time. Li Yang smiled slyly and continued.

"The spleen and stomach belong to the earth, which is the foundation of human beings, and we rely on it to absorb nutrients from food, otherwise we will only slowly age and die."

"The kidneys are water, which I also call the urinary system, and all the waste products of the body are excreted by it. Only when these five elements are normal, people will live normally and healthily. ”

Looking at the nodding action of everyone in the audience who understood clearly, well, it seems that my set is not deep, and Chinese medicine has already been studied, and everyone can understand it.

"Next, I want to talk about our brain, that is, the head, there is a line in addition to the five elements, I call it the nervous system, all our senses, actions, are received by the nervous system, and then make actions."

Everyone has never heard of this thing, although everyone knows that the brain is the most important, but how the brain works, the nerves are too small, not as easy to be studied by humans as blood vessels or urinary systems, and the things of the nervous system have not been studied thoroughly until today, Li Yang just wants to inject some forward-looking information to promote these diligent and inquisitive people to study more.

Instructed the students to catch a small tree frog and find a bottle of water from the school, Li Yang put the frog on the table, and stabbed the tree frog with a wooden stick to eat the pain and jumped around.

"Look, its brain knows that it hurts, and it will jump when it stabs it."

After Li Yang finished speaking, the students below couldn't hide their smiles, and they would definitely jump.

"Then ......" Li Yang asked the guard for a dagger, took the knife in his hand, cut off the head of the tree frog, and hung the dead body on the wall behind him.

The people below all looked at Li Yang curiously, not knowing what he was going to do. Li Yang dipped a little bit of water with a wooden stick and put it on the back of the headless tree frog, and the corpse of the tree frog twisted strangely, and its limbs were desperately pulled behind it, as if he wanted to erase the water behind it.

There was a low shout from the lecture hall, and a teacher shouted in a suppressed voice: "Tree frogs can also cheat corpses?!" ”

Li Yang smiled in his heart, this is an experiment for the introduction of the nervous system, which shows that the control of animal behavior is not only the role of the brain.

I tried my best to explain it to everyone in popular words, so that everyone was fascinated by it, and I couldn't imagine that there was such a secret in this body. Presumably, after today's vivid biomedical class, I wonder how many students who originally aspired to be generals have changed their careers to become doctors.

Although it is still unfinished, it is indeed not too early, Li Yang is not simply a teacher, he always has government affairs to deal with. After promising that Old Master Hou and Wang Er, who had bright eyes, would come tomorrow for a day, Li Yang hurriedly said goodbye and left.

After spending the last few days of his time in the Ryukyus, he hurriedly set off for Miyako Island.

At this time, the glass factory has begun large-scale production, quartz sand is not difficult to find, there are many quartz mines that can be mined in the Ryukyu Islands, but in order to make good glass products, the grade requirements for quartz ore are quite high, and the screening process of quartz sand and the subsequent firing process are even more difficult, Li Yang himself is also half a bucket of water swaying, can only give full authority to the craftsmen, with the exchange of simple formula step by step test, at least now can make more crystal clear translucent glass, The money in exchange for the product is also enough for the glass factory to operate its own hematopoiesis.

After a long period of construction of the cement plant, the kiln has been put into use, and a kiln is still being built, and the craftsmen have successfully fired several furnaces of cement after improving the air supply method, but because the trial production has just begun, the hardening speed of the burned cement is completely uncontrollable, and the material of the same furnace will also have the problem of uneven solidification, which naturally requires the craftsmen to have a headache to improve.

At this time, the technical level was backward, and the quality of the cement made was definitely not much better, but Li Yang was not prepared to use these low-quality cement to build twenty or thirty-story buildings or viaducts, and it was enough to pour the walls of the bungalows.
