Glan Natural Science Academy Chapter 20: Dissecting the frog
one morning, it passed unknowingly.
Seeing that Lei Luo seemed to have some insights into the knowledge he had narrated, Sadra was pleased.
When I thought that when my teacher explained this to myself, he seemed to be like a fantasy to myself. I didn't know why, and I was so angry with my teacher.
Junior Brother is so smart, he might be able to accomplish something in the future.
" Junior brother, the foundation of learning the profound meaning of evolution is to collect natural specimens, just as the foundation of learning the laws of nature is the cornerstone of mathematics. A scholar who studies the profound meaning of evolution, the number of specimens he analyzes and collects, and the degree of quality determine His reserves of knowledge, and in the field of scholars, knowledge is power!"
On the ice and fire bird skin handwritten notes, Lei Luo is recording his enlightenment experience.
One morning’s basic enlightenment study has benefited a lot. It has completely opened the door to Lei Luo’s eagerness to learn natural science knowledge, and has completely eliminated the awe of the great light creator from the heart. Now Sadra seems to be going to teach himself something. Something more practical.
"Brother, shall we go out to collect specimens?"
Lei Luo asked expectantly.
Sadra shook his head.
"Collecting advanced natural specimens requires scholars to go out for a long time, usually with fellow scholars of the same level, or encounters during missions out of a mercenary group. Once you have a certain degree of self-protection ability for your own zero-level academics, it will not be too late to try to go out to collect specimens."
Zero academic.
Rello thought of Ornn’s fireball technique. According to him, he couldn’t really threaten those mercenaries at all.
"Junior brother, you, like me, are of civilian origin and have not received basic enlightenment education, so let's start with the most basic literacy! As the carrier of human knowledge, words are divided into More than 16,700 basic pictographs..."
I thought of some of the past experiences, and Shadura looked regretful.
"You have to study hard. When I was studying writing with my tutor, I was so dull that I would forget it when I learned it. That’s why my tutor kept reprimanding me."
Sadra takes it for granted that Lei Luo has no foundation in writing, so he intends to start teaching from learning to write and literacy. This is why the college will arrange enlightenment tutors for every student who is studying with a contribution badge.
If Lei Luo finishes learning literacy and writing, at least a few months have passed.
literate?
Lei Luo said slowly: "Brother, I have already learned literacy in the small town church!"
"Huh?"
Sadra stopped the quill in his hand and said in surprise: "Junior, you have learned to read? That would be much easier. The instructor is really worried about it!"
After speaking, Shadra turned around and fetched two books from the shelf, namely "Dwarven Language Basic Training" and "Elvish Language Basic Training".
"Brother, since you have come into contact with enlightenment knowledge in the church, you want to talk about Elvish and Dwarf language, should you also be involved?"
The church naturally does not have literacy courses. Since the first day of the church’s seminary, it has been continuously training missionaries as its sole goal. Dwarven and Elvish languages are almost compulsory courses. This is what Shadra has Understand.
Lei Luo hesitated and said: "Although the pastor has taught a little bit, he hasn't actually applied it yet."
Elvish and dwarven languages, although Lei Luo has a certain foundation in learning, but it is not difficult to see that it is not hard to master it when communicating with Krerina on the road.
"It’s okay! You put away the grammar book first, and then you will slowly correct it! Brother, since you already have a certain foundation, our course will be much simpler, waiting for you to learn to analyze natural specimens and energy magnetic fields After that, you can ask your instructor to arrange class lessons for you and learn with other students!"
"Good!"
Lei Luo longing for the color of joy.
If it is really an ordinary civilian enlightenment study, writing literacy, foreign language, analyzing specimens, contacting energy magnetic field, a series of studies, within a few months, I am afraid it will be really difficult to get started, let alone master.
At first, Lei Luo had studied in the church for four years. This shows the huge cognitive gap between common people and nobles.
In Lei Luo's gaze, Sadra took out a box.
呱呱呱.
There were many lively frogs in the box, croaking and barking. After Sadra grabbed one from it and handed it to Leiluo, he took out one and re-covered the box.
This season, there are so many frogs. They should be specially cultivated specimens by brother.
Lei Luo clutched the frog tightly. The slimy frog was struggling constantly in his hands. It seemed that he might escape at any time. Lei Luo had to hold it firmly with both hands to prevent it from escaping.
"Natural specimens are generally divided into five categories: microorganisms, animals, plants, minerals, and fossils. For animal specimens, we generally use anatomy to fully understand their texture and operation, and then make them into organisms that can be preserved for a long time. The specimens provide us with a steady stream of wisdom and inspiration. Today we will start learning from this frog."
While talking, Shadrauo opened the toolbox and skillfully took out a thin needle from it and showed it in front of Lei Luo.
This kind of tool box is also included in the space box that Shadrauo gave Lei Luo, which contains various scalpels, pipe clamps, tweezers, needles, and so on.
"This is a piercing needle. We use it to insert the frog’s central nervous system, destroy its pain perception, and let it calm down. This facilitates our anatomy and observes and learns their physiological secrets. This method is applicable to all animal specimens. "
's focused eyes, as Shadra's piercing needle was gently inserted into the frog's body, the frog that had been struggling suddenly stopped moving, but still breathed, screaming "quack".
"Brother, you try too!"
Leello took the piercing needle that Shadrao handed over, compared to Shadrao's technique just now, and gently pierced towards the frog in his right hand.
However, the frog in his hand struggled even harder, and he let out a "croak".
"Brother, you didn’t find the right central nerve location, don’t worry, grab it and take it slowly~IndoMTL.com~ Lei Luo is embarrassed and started to catch frogs all over the room.
Satura looked at the little brother in a hurry, and couldn’t help laughing: "Junior brother, did you know that when the ancient scholars first analyzed a certain animal specimen, they would take a bite first and use the most primitive way to study , Would you like to try?"
"Forget it!"
After a while, Lei Luo finally caught the frog.
I saw some blood stains appearing on the skin of the frog that had just been pierced by Lei Luo's piercing needle, while the frog that had stopped struggling in Shadrao had no blood stains at all.
Satura leaned over, pointed to the back of the frog, and said patiently: "Here, keep to the left, you try again."
Lei Luo inserted the piercing needle as Shadrao pointed out.
The struggling frog in his hand suddenly stopped, and Lei Luo showed a surprise smile on his face. He breathed a sigh of relief and gently placed the frog on the dissection tray.
Satura put on rubber gloves and said with a focused expression: "When many scholars first learn to dissect biological specimens, they will have some negative emotions, or feelings of guilt, or excitement, fainting, etc. We We must correct our experimental attitude and treat the life and death of specimens rationally. The killing of the research process is only a necessary process for us to explore the truth and knowledge. When it is not necessary, we must avoid killing for no reason."
In the low muttering of Shadrao, the delicate scalpel slid slowly across the white belly of the frog without any hindrance.
It seems that the cut is not the frog skin, but a piece of soft fat cheese solution.
The frog on the disc had no pain, and bright red blood was flowing from the wound.
As Shadrao peeled open the incision with tweezers, the fresh and live internal organs in the frog's abdomen appeared in front of the two of them, and the heart was still beating "gudong" and "gudong".
