Chapter 163 Change the bat! Change the bat again! (6,000)
Anatomy.
Anatomy.
The light of the knife flashed.
Open the chest, open the abdomen, open the neck and head. Observe the internal organs, organs, blood vessels, omentum, and subcutaneous tissue——
When the cause of death is unknown, the scalpel is the torch that illuminates the fog in the darkness.
Gretel was concentrating on the dissection and exploration. The rabbit's lungs, internal organs, blood vessels, and bits and pieces of bleeding were everywhere. The bleeding was extensive, there were no adhesions, inflammation, or other organic lesions, and there were no sharp wounds. Basically, it can be inferred...
...It's done by ultrasonic waves.
"Um, Bernard...Bernard?"
Grete put down his scalpel and was about to call the barbarian over to stew or bake the rabbit, or do whatever he wanted to do with it. When he turned around, the barbarian picked up another rabbit and stood next to him, full of expectations.
Look at him...
The belly of the new rabbit was cleanly shaved, with a slight hint of pink, which contrasted well with the surrounding black hair. It hung in Bernard's hand, kicking its legs desperately, saying "I am very energetic"
, I don’t have heatstroke”.
Well……
Grete sweated profusely. One rabbit is not enough for you! I didn’t want to cut off the rabbit legs!
"Bernard, don't eat this rabbit yet... No, let's not do the experiment now. I have to think about it... What went wrong with this experiment? I have to think about it for a while..."
Gretel went home and finished his routine meditation. He shaped another bone for his "self" composed of spiritual power - there were only eight bones to go before it was complete - and once again devoted his energy to B-ultrasound magic. He thought about it and meditated hard.
,have a bee in one's bonnet……
Well, I tried to think about it over and over again, but I still couldn't find out where the problem was. I had no choice but to calm down and start from the description of B-ultrasound in "Medical Imaging":
"B-ultrasound uses 1 to 10 megahertz ultrasonic waves to propagate in human tissues... uh..."
1~10 MHz?
That is 1,000,000 Hz to 10,000,000 Hz?
What is the frequency of ultrasonic waves emitted by bats?
It’s over, I can’t remember...
But this time, Gretel remembered something again:
The higher the ultrasonic frequency, the worse the tissue penetration ability, but the higher the resolution of adjacent objects; the lower the frequency, the stronger the tissue penetration ability, but the worse the resolution of adjacent objects.
So when he used the echo magic before, he could "see" through the rabbit the rabbit cage, the table and the ground below, but he could not "see" the rabbit's body tissue clearly. Is it true that the frequency of the ultrasonic wave is too low?
Is there any magic that can adjust the frequency of sound waves?
Some images and sounds popped up in Gretel's mind: mineral radio, knob, "Welcome to FM 89.7 MHz..."
Stop, stop! That's listening, not sending!
In any case, it would be good to find the reason why the magic failed. Grete went straight to the laboratory after class the next day, took out five different bats, and lined them up. He picked up the rabbit, applied sweet almond oil on it, and started——
Sure enough there is a little difference!
The flying fox, which is the largest and has the widest wingspan, emits ultrasonic waves at the lowest frequency, and the images in its meditation field of view are also the fuzzy;
The most common and cheapest black bat has a slightly higher frequency and a clearer resolution, but it still cannot meet Gretel's requirements;
It is a small gray bat, only as big as Gretel's palm. The range of the ultrasonic image only covers the rabbit and the rabbit cage...
According to the size of the rabbit, if you reduce it by one circle, you can almost see the internal organs.
The idea of changing to bats was right! Gretel was very excited. However, in the last experiment, the Magic Council provided only 5 types of bats, so he...had to go to the street to buy them.
Amitabha, God bless you, the God of Nature, the God of Magic, etc. all bless you - bats, don’t be too expensive!
He couldn't afford it if it was only 5 gold coins each!
He went straight to the store where he had inquired last time. The young clerk who had promised to pay the deposit and left the goods for him had some impressions of Gretel. When he saw him come in, his eyes lit up:
"Mr. Master, you're here again! - Do you still want the bat?"
How do you know I want a bat?! Gretel was shocked: "How much does one cost?"
"...5 copper coins each, as if alive or dead."
The clerk's voice was muffled. Gretel was shocked: "Did it fall so much?"
"Isn't that true..." The young clerk sighed in frustration. While the shop owner was away, he leaned down on the counter in front of him, resting his chin between his arms. From his skull to his spine, his entire body collapsed into a soft piece.
The word "mourning" is written from top to bottom:
"I don't know which mage published an article, saying that studying bats is dangerous and will lead to disease. Now it's better. Many buyers who ordered bats don't want them anymore, and some even return them after buying them. Our store has a backlog.
There are thousands of them! If I don’t think of a way to sell them, I can’t even afford to serve them..."
There will also be a discount on this month’s salary. Not only this month, but next month, the next month, the next month, and the next month, maybe it will be discounted in half...
"Well……"
The initiator of the big price cut on bats felt a little guilty and a little happy. He blinked and moved closer:
"Does your store have a complete range of bat varieties? If so, I will buy them here instead of going elsewhere!"
"Everything is in order!" The young clerk jumped up. "We have more than ten kinds of products at home! Even if they are not all in order, I can go to other stores to purchase them! Mr. Master, sit down while I run around and collect them all for you.
Come here! How many of each do you want?"
5 copper coins each, one of each of the 20 kinds, is a gold coin. Gretel pinched his wallet, took out a gold coin between his index finger and thumb, and pushed it on the counter:
"It depends on how many species you can collect. If you have 20 species, I will buy 5 of each species first, and then I will buy more after I find the one I want."
"Okay! Don't worry, Mr. Master - otherwise, you can leave your address and I will deliver the goods to your door?"
That afternoon, when it was dark, Grete received a basket full of bats. There were forty or fifty species of bats, large and small, divided into categories. They were all dead, and each species was individually wrapped in a straw bag with paper wrapped around it.
In the strip, write the name of this bat.
Considering that in his previous life, there were only more than 900 species of bats in the world, Gretel suspected that he had collected all the bats in the country.
...The wallet is bleeding.
Gretel endured the heartache, took out half of the gold coins in his wallet, and sent the young clerk away. Turning around, facing the large basket of grinning, scary-looking things, he became angry:
"...Ouch!"
When should I try it?
The number of spells I can cast every day is limited!
Although you are doing experiments, you should try various experimental materials - for example, when Edison invented the electric light, he tried nearly 1,600 filament materials - but there is a team below!
And me?
It’s all up to me to try!
I want an assistant! An assistant!
"Grete, don't be anxious, let's try slowly." His only assistant, Bernard the Barbarian, came over to comfort him, with a considerate look on his face:
