The correct way to open the elf

Chapter 108 Father Feng's class is open
“Here, I would also like to thank the great sage Anthony and everyone who participated in the compilation of the textbook.

With the resolution of food and safety issues in the camp, children from our three tribes have been given the opportunity to receive education, which is inseparable from everyone's efforts.

I also hope that with everyone’s joint efforts, the Pupu City Campground will become even better.”

As he spoke, Feng Yu bowed to everyone.

Clarence and the students from the Alchemy Institute who came to watch gave Feng Yu applause in affirmation. The only flaw was that the others just stared at him with wide eyes, because except for the Alchemy Institute, applause was not popular in the Green Continent.

Feng Yu responded to the applause from Clarence and others with a smile.

After Clarence stopped the applause, he asked, "Darren, I haven't heard you mention the nine systems yet. Can you tell me more about them?"

Faced with the gossipy looks of these idle people who didn't have a proper job, Feng Yu could only sigh helplessly.

“In fact, it’s still the same old saying. In the end, the power system will not distinguish between you and me.

The nine systems are too large, I will write them down for you to see when I have time.

Here, I would like to tell you some interesting discoveries about the nine systems and life sciences, and I hope it will give you some inspiration. "

Feng Yu glanced at Nitia and continued, "Is there any connection between life and alchemy? In other words, will alchemy research eventually affect life sciences?

Regarding this question, our answer is yes, alchemy is closely related to life. "

Amid the crowd's incredulous and curious gazes, Feng Yu began his performance.

"We all know that blood will coagulate after leaving the body. But by adding certain alchemical reagents, the blood can be prevented from coagulating.

As everyone knows, I have started to make glass similar to magic crystal in the camp.

If we put blood into a glass tube, and observe what is left after the non-coagulated blood precipitates through the transparent glass tube, we will find that the liquid inside is divided into three layers.

The top layer of blood will be a transparent light golden color like honey, accounting for about half. The middle layer is light red, very little, no more than one tenth. The bottom layer is dark red, accounting for about a little less than half.

I will not explain here what each layer is specifically about, because it is difficult to understand and requires basic science as support, just like the elements needed for magic.

Even without adding anticoagulant reagents, the blood will still separate into layers after settling, but it will be divided into two layers. The upper layer is also light gold, but very little, and the lower layer is dark red.

If you are interested, you can find some animal blood and observe it yourself to see if it is the same as what I said.

If you are careful enough, you will find the blood vessels on the back of our wrists. People with certain combat experience know that blood vessels like these that can be seen on the skin, even if injured and damaged, are unlikely to be fatal if they are not treated.

Because the blood flow in them is slow, they heal very well.

We call these blood vessels veins, which means that the blood in them flows calmly.

But on the side of our wrist facing the palm, under the skin that is difficult to see, there are also blood vessels, and the blood in those blood vessels is brighter red than the blood in the veins.

Once damaged, these blood vessels are difficult to heal without treatment because they bleed profusely and with great jet force. This is the type of blood vessel that, once broken, will bleed continuously.

If you are interested, you can put your hand on your wrist and feel it carefully. The blood vessels hidden on the inside of the wrist are beating, and their beating frequency is the same as your heartbeat.

This kind of pulsating blood vessels can also be found in the neck, which is a fatal location. Once injured, it is basically difficult to wait for treatment and will lead to death.

We call these blood vessels arteries.”

Seeing the people present touching their blood vessels unconsciously, Feng Yu smiled and continued, "Our heart is like a steam pump. It pumps blood through arteries throughout the body by beating.

This is why the arteries keep beating at the same pace as the heart.

This is also why it is difficult to stop bleeding once these internal blood vessels are injured, because the blood inside them, like the water pipes of a steam pump, is under great pressure.

Anthony and others then realized that there are two different types of blood vessels. This knowledge was refreshing to them.

Feng Yu continued, "Now let's talk about how blood and alchemy are closely related. Of course, I only know why, and I don't understand the deeper things because I'm not studying this.

There are two types of blood vessels, and because of their different functions, the blood in them has slightly different colors, but why is this?

Every one of us needs to breathe. We cannot survive without breathing. So why do we need to breathe?
We all need to exercise and even fight. After each battle or labor, we feel very tired and our muscles ache. Why is this?

Now I want to tell you about the relationship between these three...

...So, this is the blood supply system in our life, and it is also the basis for living or being able to maintain movement. "

As Feng Yu spoke, he asked one of Clarence's apprentices to prepare a basin of water, a glass, and a cattail stalk.

The inside of mature and dried cattail stalks is hollow. Feng Yu wants to use these things to conduct a small experiment on the effects of oxygen and carbon dioxide on combustion.

Everyone saw that the small candle in the exhaled gas tank did not burn for a while before going out like the one in the air tank, but went out immediately. They believed Feng Yu's words more.

“See, this is the air we exhale, it changes, some of it that makes the fire burn is absorbed by our body, and the air that is released does not make the fire burn.

You may not be able to have an intuitive feeling about oxygen and iron, but you can still see this kind of experiment. This is what I said about the alchemical changes of oxygen in our body that make us move.

Life is actually very complex. We have been trying hard to study life, but we still cannot explore all the mysteries of life. But even so, we have learned a lot of the mysteries of life.

If we want a better existence, we must understand why we exist.

Just like if you want to make alchemy and prepare a potion, you need to understand the properties of the materials. Only by finding the basic rules from the root, we will not be completely clueless when facing unknown changes. "
