Chapter 20 Dissecting a Frog

The whole morning passed by unconsciously.

Seeing that Lei Luo seemed to have some insights into the knowledge he told, Shadra looked pleased.

I remember when my mentor explained this to me, it seemed like a fantasy to me. I had no idea why and made my mentor so angry.

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

"Junior brother, the basis for learning the mysteries of evolution lies in collecting natural specimens, just like the basis for learning the laws of nature is the cornerstone of mathematics. For a scholar who studies the mysteries of evolution, the number and quality of specimens he analyzes and collects determines his knowledge reserves, and in the field of scholars, knowledge is power!”

In the Ice Firebird Skin Notes, Lei Luo was recording his enlightenment experience.

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

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

Lei Luo asked expectantly.

Shadra shook his head.

"Collecting high-level natural specimens requires scholars to go out for a long time. Generally, they are accompanied by scholars of the same level, or they meet by chance during missions when joining a mercenary group. There is no rush. You need to start with the basic courses first, and wait until you master your own zero Level academic, once you have a certain ability to protect yourself, it’s not too late to try going out to collect specimens.”

Zero academic level.

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

"Junior brother, like me, you are from common people and have not received basic enlightenment education, so let's start with the most basic literacy! As the inheritance carrier of human knowledge, writing has been divided into sixteen thousand and sixty thousand along with the history of human development. More than 1,700 basic hieroglyphics..."

Thinking of some of his past experiences, Shadra looked regretful.

"You have to study hard. When I was learning writing from my tutor, I was always scolded by my tutor because I was too stupid and forgot what I learned."

Shadra took it for granted that Lei Luo had no foundation in writing, so he planned to start teaching him by learning to write and read. This is why the academy will arrange an enlightenment tutor for each student who holds a contribution badge to study.

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

Literate?

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

"ah?"

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

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

"Junior brother, since you have been exposed to enlightenment knowledge in the church, you should also be involved in Elf and Dwarf languages, right?"

Naturally, the church does not have literacy courses. From the first day of its birth, the church's seminary has been continuously cultivating missionaries as its only goal. Dwarf and Elf languages ​​are almost compulsory courses. Shadra naturally knows this.

Lei Luo hesitated: "Although the pastor has taught some, he has never applied it in practice."

Although Lei Luo has a certain foundation in learning Elf and Dwarf languages, it is not difficult to see from communicating with Krelina on the way here that there is really no 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 courses will be much simpler. After you learn to analyze natural specimens and energy magnetic fields, You can ask your instructor to arrange classes for you and study with other students!"

"good!"

Lei Luo looked forward to the joy.

If an ordinary civilian were to learn how to write, read and write, learn foreign languages, analyze specimens, and come into contact with energy magnetic fields, it would be difficult to get started in just 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.

As Lei Luo watched, Shadra took out a box.

Gua Gua Gua.

Inside the box were many lively frogs, croaking and croaking. After Shadra grabbed one from inside and handed it to Lei Luo, he also took out one and closed the box again.

There are so many frogs this season. They should be the specimens specially bred by Senior Brother.

Lei Luo held the frog tightly, and the slimy frog kept struggling in his hands, as if it might escape at any time. Lei Luo had to hold on tightly 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 dissection to fully understand how their texture works, 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.”

As he spoke, Shadra opened the tool box, skillfully took out a thin needle and showed it in front of Lei Luo.

There is also a tool box of this kind in the space box that Shadra gave to Lei Luo. Inside it is a variety of scalpels, pipe wrenches, tweezers, needles, etc.

"This is a bone-piercing needle. We use it to insert into the central nervous system of the frog to destroy its pain perception and make it quiet, which facilitates our dissection and observation and learning of their physiological mysteries. This method is applicable to all animal specimens."

With focused eyes, as Shadra's bone-piercing needle was gently inserted into the frog's body, the frog that had been struggling suddenly stopped moving, but it was still breathing and screaming "croak".

"Junior brother, you try too!"

Lei Luo took the bone-piercing needle handed over by Shaduoluo, compared with Shaduoluo's technique just now, and stabbed it gently into the frog in his right hand.

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

"Junior brother, you didn't find the right central nervous system location. Don't be anxious, just grab it and take your time."

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

Seeing his junior brother in a hurry, Shadra couldn't help laughing and said: "Junior brother, do you know that when ancient scholars dissect a certain animal specimen for the first time, they will take a bite first and study it in the most primitive way. You want to Don’t you want to 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 thorn needle, but there were no blood stains on Shadra's frog that had stopped struggling.

Shadra came over, pointed to a spot on the frog's back, and said patiently: "Here, stay a little to the left, and you can try again."

Lei Luo inserted the bone-piercing needle according to Shadra's instructions.

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

While putting on rubber gloves, Shadra said with a focused expression: "When many scholars first learn to dissect biological specimens, they will have some negative emotions, or a sense of guilt, or excitement, fainting of blood, etc. We must correct ourselves. We must adopt an experimental attitude and treat the life and death of specimens rationally. Killing during the research process is only a necessary process for us to explore truth and knowledge. We must avoid unreasonable killing when it is not necessary."

In Shadra's low murmur, like a soliloquy, the delicate scalpel slowly slid across the frog's white belly without any hindrance.

It's as if what's being cut is not a frog's skin, but a piece of soft, fatty cheese.

The frog on the dissection plate could no longer feel any pain, and bright red blood was flowing from the wound.

As Shadra used tweezers to peel off the incision, the fresh internal organs inside the frog's abdomen were revealed in front of the two of them, with their hearts still beating "gudong" and "gudong".
