Chapter 422 The Seventeenth Electrocardiogram Experiment

Chapter 422 The seventeenth electrocardiogram experiment...

In the past few days that Gretel has been practicing with animals, Ophelia has also found a target for her training. A ready-made group of barbarians were lined up in front of her, and she could summon them and wave them away, using [Detection Magic] to take photos over and over again:

"Gretel! Why doesn't something look right here?"

"Let me take a look...ma'am, his leg bone was broken before. It wasn't connected well and it's a little crooked."

"Gretel! What are these light and dark things?"

"It's nothing, just constipated."

"Gretel——"

Barbarians can make do without humans. When Grete began to study [Detection of Rot Sacs and Modifications], he gave Ms. Silver Dragon a complete set of frontal and lateral X-ray images of the human body that he had drawn before. Now, Ms. Silver Dragon is holding the [Detection Magic] (X-ray version) he provided, and is enjoying herself...

Well, although there is some difference in physique between humans and barbarians, they are much better than dwarves. That's a difference in proportion, just kidding!

Even though Ms. Ophelia is an out-and-out silver dragon under the appearance of an elf, when she took the thick album, her slender hands sank:

Grete is so young that he can almost be considered a cub in the eyes of the Immortals. How many patients did he treat and how much time did he spend to compile such a thick book?

"This is not just my job." Grete lowered his head slightly to avoid her surprise and exclamation. He drew the pictures one by one with his own hands, but every key point and every noteworthy point in the picture is the result of thousands of doctors summarizing it bit by bit on patients.

Photograph, compare, summarize, and write into a book. Revise again and again, iterate again and again...

Going further back, the world's top scientists, with infinite enthusiasm and curiosity, revealed the secrets of radioactivity to mankind;

It was the sages who explored the functions and harms of X-rays at the expense of their lives and health;

It was the people with lofty ideals who risked their lives, slept in the open air, and walked day and night during the war, to carry China's only 50 grams of radium south, and to preserve the precious fire for the nuclear industry...

How can you throw it lightly?

How can you live up to it!

Therefore, as long as he has the conditions to treat a patient, he will draw an image diagram. I have been painting by midnight for many days and have accumulated it until now. Unknowingly, it is already a thick book.

"Okay, okay... I've finished copying it, and I'll give it back to you." Ophelia threw the album back into his arms, watched him hurriedly stuff it into the space bag, and snapped his fingers:

"I've already understood your [Detection Magic]. It's nothing more than memorizing the images and practicing more. What about the other magic? I've already mastered it. Do you want to watch me try it?"

"No!" Gretel suddenly raised his head and his voice suddenly became louder:

"Don't practice on people! If you want to practice, practice on animals first!"

"Really?" Ophelia joked with him with a smile. Stretch out an arm, lift up your sleeve, and reach out to him:

"Try it. Can you tell it using the ultrasonic magic you mentioned?"

Grete threw the glycerin to her with a dark face. Just look at it. Although B-ultrasound is generally used to see organs, blood vessels, bones and joints are not impossible to observe; however, don't ask me to apply oil for you!

do it yourself!

Ophelia unscrewed the cap of the glycerin bottle in a good mood, poured it into her arm boldly, and drank half of the bottle on the spot. After wiping it on twice, Gretel seemed to see a sparkling silver light under the oily light. Wait, dragon scales?

What is the principle behind your transformation technique? Why do dragon scales still appear under the body of an elf?

He cursed and put his fingers up. The magic is activated, the ultrasonic waves are emitted, and the B-ultrasound observation begins—begin!

"...Wait a minute, madam, can you take the dragon scales back? I feel like I'm not observing the human body, but doing metal flaw detection... I just see the gaps in the scales!"

Fortunately, the ultrasonic frequency of metal flaw detection is generally 0.5 ~ 20MHZ, which is similar to the frequency used by B-ultrasound. Otherwise, if he sends the ultrasonic wave down, not to mention scales, he probably won't be able to see anything...

"Can't you see it anymore?"

"Yeah, I can't see it. It's blocked by a silver plate outside! Madam, you can practice with animals first. Pay attention to controlling the frequency and not harming the animals..."

"Hey, wait a minute!"

The silver dragon girl called out from the side.

Serira and Gretel have traveled together for so long, and have long since learned X-ray magic - of course, whether they can use it well and interpret the images is another matter. However, when her aunt was holding the album and chewing on it, she learned B-ultrasound magic as soon as she got started.

At this moment, the silver dragon girl was holding a shaved live rabbit and was looking at it over and over. Seeing Gretel turning around to leave, she hooked her fingertips, and a wisp of long wind gently swept out and entangled Gretel's feet:

"You're here! Is what I saw correct?"

"You -" Grete wanted to say, but you copied the image! He paused for a moment before he spoke, then turned to Ophelia:

"Madam, could you please study how to display the pictures in the meditation field of view to the outside world and print them on paper? This way, it will also be convenient for me to explain to everyone what the pictures I see represent..."

Ms. Yinlong plunged into research. After Gretel cured the barbarian, he turned around and fell into another research.

...So, how to connect the current drawn from the heart to the cloud screen?

In front of him was a rabbit with its chest and belly shaved and its head turned upward. Take a thin silver needle in one hand, weigh it, and stick it between the left edge of the sternum and the right edge of the fourth rib. Fortunately, rabbits, like humans, have 12 pairs of ribs, so he doesn't have to recalculate the lead positions...

"Summoning the cloud screen... descends... falls above the silver needle... three millimeters... two millimeters... one millimeter..."

The cloud screen shook for a while. Then, the tip of the silver needle on the left pierced the cloud screen, and the moment it didn't touch the right side, it quietly collapsed.

Gretel was expressionless. Pull out the silver needle and spread out the notebook.

The oak stick in the chest pocket stretched out a root, rolled up the [Endless Ink Pen] and landed on the notebook, and wrote:

"The 17th electrocardiogram experiment failed."

"Reason for failure: The silver needles did not enter the cloud screen at the same time, and the elements were disrupted and disintegrated."

"Improvement method: 1. Pay attention to the timing of the cloud screen landing and insert the silver needles at the same time; 2. Confinement the experimental subjects to prevent the silver needles from moving; 3. Connect wires to the top of the silver needles and fix them on a certain plane to maintain a consistent height. "

Well, the third method seems more reliable. After all, the electrocardiogram requires 12 leads. The problem is that after the weak myocardial electricity passes through the wire, it has been so attenuated that it cannot be seen...

Should we develop superconductivity? ——By the way, what kind of metal should superconducting wires be made of, and how low should the temperature be?
