The correct way to open the sprite

Chapter 108 Father Feng's Small Classroom Begins
"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 the food and safety issues in the camp, the children of our three ethnic groups have the opportunity to receive education, which is inseparable from everyone's efforts.

I also hope that with the joint efforts of everyone, the Cattail City Camp will become even better. "

With that said, Feng Yu bowed to everyone.

Clarence and the students who came to watch from the Alchemy Research Institute gave Feng Yu applause and affirmation. Xing applauds it.

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

After stopping the applause, Clarence asked, "Darren, I haven't heard you talk about the Nine Systems, can you tell me in detail?"

Faced with the gossiping eyes of these idlers who didn't have a serious job, Feng Yu had no choice but to sigh helplessly.

"Actually, it's still the same sentence, the power system goes to the end, it doesn't distinguish between you and me.

The nine system is too huge, I will write it down for everyone to see when I have time.

Here, let me tell you some interesting discoveries about the nine major systems and life sciences, and hope to give you some inspiration. "

Feng Yu glanced at Nitya, and then said: "Is there any relationship between life and alchemy? In other words, after the research of alchemy, will it also affect the science of life?

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

Under the unbelievable and curious eyes of everyone, Feng Yu started his performance.

"We all know that blood will coagulate after being separated from the body. But by adding certain alchemy reagents, the coagulation of blood will be prevented.

As you all know, I have started firing glass that resembles magic crystals in the camp.

If blood is put into a glass tube, and we observe the things after the uncoagulated blood settles through the transparent glass tube, we will find that the liquid inside is divided into three layers.

The uppermost layer of blood will be transparent and light gold like honey, accounting for about half of it, the middle layer is light red, very little, no more than one-tenth, and the bottom layer is dark red, about half less.

I won't explain what each layer is here, because it is difficult to understand and requires basic science to support it, just like magic requires elements.

Without the addition of that anticoagulant reagent, the blood will also separate after precipitation, but it will be divided into two layers. The upper layer is also light gold, but it is rare, 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. Anyone with certain combat experience knows that even if the blood vessels that can be seen on the skin are injured and damaged, they will still be damaged if they are not treated. Hard to kill.

Because the blood in them flows slowly, they heal well.

Our side calls this kind of blood vessel venous blood vessel, which means that the blood in it flows calmly.

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

If this kind of blood vessel is damaged, it is difficult to heal without treatment, because their bleeding volume will be very large, and they are very ejective. Once damaged, this kind of blood vessel will bleed continuously.

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

This kind of beating blood vessel is also found in the neck, which is a fatal position. Once injured, it is basically difficult to wait for treatment and it will lead to death.

These blood vessels are called arteries. "

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

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

This is also the reason why such built-in blood vessels are difficult to stop bleeding once they are injured, because the blood inside them, like the water pipe of a steam pump, has a lot of pressure inside. "

Only then did Anthony and the others realize that there are two types of blood vessels. This kind of knowledge is refreshing for them.

Feng Yu went on to say: "Now let's talk about blood and alchemy. Of course, I only know why, and I don't understand too deep things, because I don't study this aspect.

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

Each of us has to breathe, and we cannot live without breathing, so why do we breathe?
We all have to exercise, even fight, and every time we finish fighting or working, we feel very tired and our muscles are sore. Why?

What I want to tell you now is the relationship between these three...

...So, this is the supply system completed by blood in our life, and it is also the foundation of life or being able to keep moving. "

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

The inside of the mature and dried cattail stalks is empty. Feng Yu wants to take these things and give them a small experiment on the combustion of oxygen and carbon dioxide.

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

"See, here's the air we exhale, and it's changed, and something in it that allows the fire to burn is taken up by our body, and the gas released doesn't allow the fire to burn.

You may not be able to feel intuitively about oxygen and iron, but you can still see this kind of experiment, which is why I said that oxygen undergoes alchemical changes in our body to make us exercise.

Life is actually very complicated. We have been working hard to study life, but we still can't explore all the mysteries of life, but even so, we still understand a lot of mysteries of life.

In order to exist better, we must understand why we exist.

It's like knowing the characteristics of materials if you want to make gold and configure potions. Only by fundamentally finding the basic rules can we not be ignorant when facing unknown changes. "
