Emiya hung the developed X-rays on a white glass plate and stood in front of them to examine them carefully.

In the black negative, the skeletal shape of the white forearm and palm is clearly revealed.

"It's amazing."

Lai Shiyu tilted her head sideways, and she didn't need to remove the skin and flesh on the outside, so she could see the shape of her bones so clearly, which was really incredible.

"It doesn't seem like there's much of a problem."

Wei Gong studied it carefully, then turned to look at Cui Xiaoxiao, who was sitting in the distance.

"What do you think?"

Cui Xiaoxiao rolled her eyes.

Wei Gong, a guy who doesn't know how to pretend to understand, and he doesn't study medicine, why do you want to pretend to be a doctor, don't you still have to ask me in the end?

And this ancient skill, which is examined by the human eye, has long since disappeared in our time.

Basically, it is diagnosed and treated by machines, and the human eye is time-consuming and error-prone, so why is it so laborious.

She pretended to approach the film and then observed it from top to bottom.

"Hmm. There should be no problem. ”

In fact, Cui Xiaoxiao doesn't understand either.

But at least the bones on the film look like normal people, without obvious bending and shattering, as for the details, who knows what's going on?

Hearing this, Lai Shiyu was a little relieved.

However, for her, her physical condition is clearer than anyone else, and according to her current Ninefold Realm, recovery is only a matter of a day or two.

She didn't care about the results of the examination, but the invisible light inspection just now made her quite interesting.

"Master of the Guard." Lai Shiyu opened her mouth, "What kind of dwarf did you just say?" Is it possible to use other parts of the body besides the hands? ”

"Yes," Wei Gong nodded, "It's just that if you want to examine the organs, you need to use contrast fluid to enhance the contrast, so that you can have a clearer imaging effect." Different contrast agents are used for different parts...... I don't know if there's any material to make here, maybe I'll have to go out and buy some and come back......"

Speaking of this, Wei Gong raised his head to look at her, "Is there anything wrong with you?" I'll take a look at it for you. ”

"Huh!? Yes? No need. ”

Lai Shiyu covered her chest tightly with her hands, looking scared.

What kind of light is that, doesn't it see all the people?

"I know what you're thinking."

Cui Xiaoxiao, who was sitting in the distance, said, "After the invention of X-rays at the beginning, many people felt that there was no privacy at all, and even launched protests against the research and use of X-rays.

She scooped a scoop of ice slurry from a nearby cup and put it in her mouth, then closed her eyes with an expression of enjoyment.

After Jian Rin Sakura issued a fasting order, there was no cost, only clean water and low temperature, and ice slurry mixed with a little sugar and fruit has become Cui Xiaoxiao's favorite delicacy every day.

Especially in a tropical country like Dream Sword Country, it can be said to be a luxury.

Cui Xiaoxiao finished eating the food in her mouth and continued, "But these are all stupid attacks made by some idiots who make judgments because they don't understand science. ”

Speaking of this, she glanced sideways at Lai Shiyu.

I don't know if the other party is really stupid or too generous, I didn't care too much about her insinuation that she was ignorant, but looked at her with interest.

This damn thing, it's like Kenrin Sakura!

"So what is it actually like?" Lai Shiyu asked in a kind tone, just like a good baby who is eager to learn and ask the teacher for advice.

"In fact, because of its short wavelength and high energy, when X-rays shine on matter, only part of it is absorbed by the substance, and most of it passes through the interatomic space, showing a strong penetrating ability. The ability of X-rays to penetrate matter is related to the energy of X-ray photons, the shorter the wavelength of X-rays, the greater the energy of the photons, and the stronger the penetrating force. The penetration of X-rays is also related to the density of the substance, and the differential absorption property can be used to distinguish between substances with different densities. Human flesh and skin, on the other hand, are relatively dense and do not block X-rays. Unless you apply a blind emulsion or contrast solution, such as barium sulfate, to the entire layer of skin. ”

Lai Shiyu looked dazed, and she couldn't understand what Cui Xiaoxiao was saying at all.

"However, X-rays also have great side effects on the human body, so it's best not to take multiple shots in a short period of time."

Cui Xiaoxiao took a bite of ice slurry and continued, "In fact, the technology of human examination through X-rays has been replaced by nano human examination robots as early as the 22nd century. ”

Lai Shiyu raised her head in confusion and looked at the palace.

Cui Xiaoxiao's face was full of pride, "As for nanotechnology, ahhhh......h

Even Wei Gong recognized the seriousness of the matter, and nervously ran over to cover Cui Xiaoxiao's mouth.

"Ah...... I'm sorry, but this sister of mine just likes to talk nonsense, and she thinks about things that are also wild. ”

Cui Xiaoxiao was suffocated by him for a while, and finally broke free from his palm, and quickly lowered her head and took a few breaths of air.

"Humph!" She clasped her hands and turned her face away, not wanting to talk to him any more.

"However, this kid often watches me do things, and I've learned a little bit," Emiya explained in a serious manner, "As for the principle of human examination of this X-ray, as she just said, X-ray can show the denser part of the human body because of its strong penetration, and the skin and flesh outside the bones are generally not imaged, so you can rest assured." ”

"I see." Lai Shiyu chuckled sideways.

However, Emiya saw the X-rays and suddenly thought, what would happen if X-rays could be used to forge swords?

A long sword with its own cold light came to his mind, stuck straight into the center of the square, surrounded by distorted corpses.

Within a radius of a hundred miles, there were no living creatures, even plants withered, dark clouds surged in the sky, and strong winds whistled through the yellow sand.

Radiant Sword ......

emmmm, it doesn't feel good, it's like the end of the world.

Emiya shook his head, dispelling the thoughts in his head.

He raised his head to look at Lai Shiyu.

"Then since there is no problem with the results of the examination," Emiya took a step outside, and then made a gesture of please, "Miss Shiyu, please come with me and tell me what kind of sword you want." ”
