Chapter 20: Dissect a frog

Views:

The whole morning passed unknowingly.

Seeing that Lei Luo seemed to have some insights into the knowledge he had narrated, Shatuoluo looked relieved.

I think that when the tutor explained these things to me, it seemed like a fairy tale to me, completely ignorant of the reason, and made the tutor very angry.

Junior brother is so smart, maybe he will be able to achieve something in the future.

"Junior brother, the basis of learning the mysteries of evolution lies in the collection of natural specimens, just like the foundation of learning the laws of nature is the cornerstone of mathematics. A scholar who studies the mysteries of evolution, the number of specimens he dissects and collects and the quality of the samples determine his knowledge. reserves, and in the field of scholars, knowledge is power!"

On the Ice Fire Bird Skin Notebook, Lei Luo is recording his enlightenment experience.

The basic enlightenment study in the morning has benefited a lot. It has completely opened the door to Lei Luo's desire to learn natural science knowledge, and completely eliminated the awe of the great and bright Creator. Now Shatuoluo seems to be teaching himself some more practical things. something.

"Brother, shall we go out to collect specimens?"

Lei Luo asked expectantly.

Satoro shook his head.

"Collecting advanced natural specimens requires scholars to go out for a long time. Usually, they are accompanied by scholars of the same level, or they meet by chance during missions when joining the mercenary group. This is not urgent. You need to learn the basic courses first, and wait until you have mastered your own. It is not too late to try to go out to collect specimens after you have a certain self-protection ability."

Level zero academic.

Lei Luo thought of Ornn's fireball technique. According to him, it couldn't really threaten those mercenaries at all.

"Junior brother, you are the same as me. You are a commoner. You have not received basic enlightenment education, so let's start with the most basic literacy! As the carrier of human knowledge, characters are divided into 16,000 More than 1,700 basic pictographs…”

Thinking of some past experiences, Shatuoluo looked regretful.

"You have to study hard. When I was learning characters with my tutor, I was always reprimanded by my tutor because I was too dull and would forget what I learned."

Shatuoluo took it for granted that Lei Luo had no foundation in learning characters, so he planned to start teaching from learning to write and read. This is why the academy will arrange an enlightenment tutor for every student who is studying with a contribution badge.

In that case, at least several months would have passed by the time Lei Luo finished learning how to read and write.

Literacy

Lei Luo said slowly: "Brother, I have already learned how to read in the church in the small town!"

"ah?"

Shatuoluo stopped the quill in his hand, and said in surprise: "Junior brother, you have already learned how to read? Then it will be much easier, the teacher is really worrying for nothing!"

After finishing speaking, Shatuluo turned around and took two books from the bookshelf, namely "Basic Training in Dwarf Language" and "Basic Training in Elvish Language".

"Junior brother, since you have been exposed to enlightenment knowledge in the church, you should also have something to do with elvish and dwarf languages, right?"

Naturally, the church does not have literacy courses. From the first day of the birth of the church seminary, the only goal is to continuously train missionaries. Dwarven and elf languages are almost compulsory courses, which Shatuoluo naturally understands.

Lei Luo hesitated and said, "Although the pastor has taught some, he hasn't applied it in practice yet."

Although Lei Luo has a certain foundation in learning Elvish and Dwarf languages, it is not difficult to see from the communication with Clarina on the way that this is really not a mastery.

"It doesn't matter! You put away the grammar book first, and I will correct it for you later! Junior brother, since you already have a certain foundation, our next course will be much simpler. Let the instructor arrange class courses for you, and study with other students!"

"good!"

Lei Luo looked forward to the color of joy.

If it is really an ordinary commoner's enlightenment study, writing and literacy, foreign language, specimen analysis, exposure to energy magnetic fields, a series of learning, I am afraid it will be really difficult to get started in a few months, let alone master it.

Back then, Lei Luo had studied in the church for four years, which shows the huge cognitive gap between commoners and nobles.

Under Lei Luo's gaze, Shatuoluo took out a box.

Quack quack.

Inside the box were many alive and kicking frogs, croaking and croaking. After Shatuola grabbed one from the inside and handed it to Lei Luo, he took out one himself and re-closed the box.

There are so many frogs in this season, it should be the specimens specially bred by senior brother.

Lei Luo held onto the frog tightly, the slimy frog struggled in his hand, it seemed that it might fall out of his hand at any time, Lei Luo had to use both hands to hold it tightly 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 dissection to fully understand their texture and operation, and then make biological specimens that can be preserved for a long time. We provide a steady stream of wisdom and inspiration, let's start learning from this frog today."

While talking, Shatuoluo opened the toolbox, skillfully took out a thin needle from it, and showed it in front of Lei Luo.

There is also a toolbox of this kind in the space box given to Lei Luo by Shatuoluo, which contains various scalpels, pipe wrench, tweezers, needles and so on.

"This is a bone-piercing needle. We use it to insert the frog's central nervous system to destroy its pain perception and make it quiet. It is convenient for us to dissect and observe and learn their physiological mysteries. This method is applicable to all animal specimens."

Focused eyes, following Shatuoluo's bone-piercing needle gently inserted into the frog's body, the struggling frog suddenly stopped moving, but was still breathing, "croaking".

"Junior brother, try it too!"

Lei Luo took the bone-piercing needle handed by Shatuoluo, compared with Shatuoluo's technique just now, and lightly pierced the frog in his right hand.

However, the frog in his hand struggled even harder, and with a "croak", it came out of his hand.

"Junior brother, you didn't find the right position of the central nervous system, don't worry, grab it and take your time."

Lei Luo was ashamed and started catching frogs all over the room.

Sha Tuoluo looked at the little junior brother in a hurry, and couldn't help laughing: "Junior brother, do you know that when ancient scholars dissected a certain animal specimen for the first time, they would take a bite first and study it in the most primitive way. Don't try?"

"forget it!"

After a while, Lei Luo finally caught the frog.

I saw some blood stains on the skin of the frog that had just been pierced by Lei Luo's bone-piercing needle, while the frog that Shatuluo had stopped struggling had no blood stains at all.

Sha Tuola leaned over, pointed to a spot on the frog's back, and said patiently: "Here, keep to the left, and try again."

Lei Luo inserted the bone-piercing needle as Shatuoluo pointed out.

The struggling frog in his hand suddenly stopped, and Lei Luo showed a surprise smile on his face, heaved a sigh of relief, and gently placed the frog on the dissecting tray.

While putting on the rubber gloves, Shatuoluo focused his expression and said: "When many scholars first learn to dissect biological specimens, they will have some negative emotions, or guilt, or hyperactivity, haemorrhage, etc. We have to correct ourselves The experimental attitude, the rational treatment of the life and death of the specimen, the killing of the research process is only a necessary process for us to explore the truth and knowledge, and when it is not necessary, we must avoid killing for no reason.”

In Shatuoluo's low-pitched murmur, the delicate scalpel slowly slid across the frog's white belly without any hindrance.

It seemed that what was cut was not the skin of the frog, but a piece of soft, greasy cheese.

The frog on the dissection plate no longer felt any pain, and bright red blood flowed from the wound.

As Shatuluo peeled off the incision with tweezers, the fresh viscera in the frog's abdomen appeared in front of the two, and the heart was still beating "gudong" and "gudong".
