"I was working as a pastry chef in Paris, and I came back to my country to sort out my grandmother's belongings, and while I was sorting them out, I suddenly noticed that my great-grandfather had drawn a picture, but it was a little broken in the middle."

As she spoke, Natsumi Kasaka took out a piece of paper and spread it on the table.

Chairman Suzuki looked at the picture carefully, "Memories! It's an egg of memories indeed! ”

Then he was a little uncertain, "But there are gems on it?" ”

Mori Kogoro on the side said, "Maybe it was originally inlaid with gemstones, but it fell off." ”

Conan, on the other hand, walked over and said after looking at the picture for a while, "Could it be that there were originally two eggs on this?" ”

Several people looked at him in surprise, and Conan continued: "Because you see, if there is only one, the outline of this egg will not fit, so could it be that there are two eggs in the original picture, but the middle part has been torn off." ”

With that, Conan picked up the Egg of Memories and looked left and right, and suddenly, under his play, a mirror fell from it.

Maori Kogoro was a little angry, "What are you doing, little ghost!" ”

Conan hurriedly said, "A mirror has been removed!" ”

Maori Kogoro's eyes widened, "What! ”

Xiaolan on the side was also a little anxious, "Conan! ”

The garden on the side hurriedly comforted: "It's okay, the mirror is easy to disassemble, it seems that it was installed later." ”

Conan looked at the mirror with his eyes, and suddenly, his lenses lit up.

"Mr. Nishino, please turn off the lights."

Maori Kogoro was a little angry, "Hey, don't mess around with you little ghost!" ”

The lights are turned off, and Conan pulls out a watch-shaped flashlight and shines a light at the lenses.

An image of a castle is reflected on the wall.

Siruov was a little surprised and said, "Why is there an image?" ”

The cadre on the side said: "It's the magic mirror!" ”

"Magic Mirror?"

"I've heard that there are magical mirrors in Japan and China. ”

"The mirrors are specially finely treated, and some Catholics in hiding in Japan use the crosses reflected on the walls to pray. ”

Xiaolan looked at Yuki Shirakawa beside her with some curiosity, "Harina, do you know this kind of mirror?" ”

In her eyes, if you don't understand something, you can know the answer by asking Haruna.

Hearing her voice, everyone on the side looked over like this white-haired girl.

Looking at everyone's curious eyes, Yuki Shirakawa nodded, "I do know something." This mirror should be similar to a translucent mirror. ”

"Translucent?"

Yuki Shirakawa nodded, "That's right, it's the translucent mirror, the translucent mirror is a bronze mirror called the "magic mirror" with special effects made in the middle and late Western Han Dynasty of China. Embodying the principles of optics and mechanics, the translucent mirror is named because the picture on its back can be reflected on the wall when exposed to sunlight.

The translucent mirror was first recorded in the "Mengxi Writings" by Shen Kuo, a scientist in the Northern Song Dynasty of China: there is a translucent light in the world, and there is an inscription on the back. In order to learn from the sunlight, the back text and the two crosses are all transparent on the wall of the house, and they are clear. ”

Everyone nodded as if they didn't understand.

Conan on the side also lamented the breadth of Shirakawa Yuki's knowledge.

Yuki Shirakawa continued, "As for its principle, it is caused by the fact that there are many small uneven curvature differences in the mirror surface. The mirror surface of the graphic is slightly concave, and the mirror surface of the non-graphic area is slightly convex. The light in the concave area converges, and the light in the convex part diverges, and the bright and dark parts corresponding to the image behind the mirror appear in the image, thus forming the mirror back image and text on the wall. ”

After listening to her explanation, everyone nodded, and Chairman Suzuki looked at her in admiration: "Your knowledge is really quite extensive, amazing!" ”

Yuki Shirakawa shook his head, "President Suzuki has a good reputation. ”

President Suzuki smiled, "Eh, you're a friend of the garden, just call me Uncle Suzuki." ”

Yuki Shirakawa smiled and said, "Okay, Uncle Suzuki." ”

Then the conversation returned to the pattern.

Natsumi Kasaka looked at Mr. Sawabe on the side and asked uncertainly, "Mr. Sawabe, this city?" ”

Sawabe nodded, "Yes, there's nothing wrong with Yokosuka's castle!" ”

Hearing their words, Xiaolan asked with some curiosity, "Is Yokosuka's castle the one that often appears in advertisements?" ”

Natsumi Kasaka nodded, "That's right, that castle was built by my great-grandfather, and my great-grandmother is in charge. ”

Mori Kogoro suddenly said, "By the way, Miss Natsumi, as far as I know, these two eggs were made by your great-grandfather, right?"

Your great-grandfather once made these two eggs with your great-grandmother after the Russian Revolution and brought them back to Japan.

Perhaps the gem on the second egg was sold to build the castle in Yokosuka, and the first egg was hidden in the castle and then used this magic mirror to tell us this information. ”

I have to say that Mori Kogoro's reasoning still makes some sense.

Natsumi Kasaka looked for a moment from the bag, "Actually, in addition to the picture, there is also this old key, are you talking about this?" ”

Mori Kogoro said firmly, "In my opinion, this is the key to the place where the second egg is hidden." ”

Siruov touched his chin and said, "Dream eggs with gems!" ”

The cadre on the side also said: "If you find a billion worth of 1 billion, oh no, it must be worth more than 1.5 billion!" ”

At this moment, Natsumi Kasaka sent an invitation to Kogoro Mori, "Mr. Mori, then when you arrive in Tokyo, I hope you can go to the castle with me?" ”

Mori Kogoro agreed, "Of course it's no problem!" ”

Hearing this, Siruoufu on the side, Qianjiangyi, Hanchuan Long and Pu Si Qinglan all rushed to go, which was agreed by Kasaka Natsumi.

……

"Don't move!"

In the room, Ran was gently bandaging Kidd's pigeon.

Xiaolan said with a smile: "The bleeding has stopped, as long as the injury is healed, you can fly." ”

Conan was also pleased, "Really? That's great! ”

Xiaolan sat down, "I don't know if Kidd is dead." ”

Yuki Shirakawa said with a smile: "That guy won't die so easily, don't worry!" ”

There was a knock on the door.

Xiaolan opened the door and saw Han Chuan standing at the door with a camera, "Yes, that's it, I took a picture!" ”

With that, he turned and left.

Looking at his back, I really don't understand what he's doing.

At this time, the voice of the garden sounded from behind him, "Hey, Xiaolan, and Qingna, I'm here to play with you!" ”

Looking back, I found that Sonoko, Natsumi Kasaka and Secretary Nishino.

Xiaolan invited them into the room together.

But Secretary Nishino left in a hurry as soon as he entered the room for some reason, leaving Xiaolan a little confused.

Yuan Zi laughed: "It seems that we have too many beautiful women here, and he is shy!" It's so cute. ”

Then, she said, "By the way, there is also Miss Qinglan, I'll call her!" ”

About what this "magic mirror" is in the magician at the end of the century, I didn't say anything on the Internet, so I checked it myself, and found that this kind of translucent mirror made in the middle and late Western Han Dynasty in China is the most similar, and coincidentally, the translucent mirror is also called "magic mirror".

The reason why it is called a translucent mirror is because when the light hits the mirror surface, the pattern on the back of the mirror will be reflected on the wall facing the mirror. According to the research of relevant experts, it is believed that in the casting process of this kind of copper mirror, the concave and convex parts of the pattern pattern on the back of the mirror are different in thickness, and the casting stress is generated by solidification and contraction, and the compressive stress is generated by grinding after casting, thus forming elastic deformation in physical properties. When grinding to a certain extent, this elastic deformation is superimposed to produce a corresponding curvature between the mirror surface and the mirror back pattern, resulting in this light transmission effect.

Shen Kuo, a scientist in the Northern Song Dynasty, wrote in "Mengxi Pen Talk: Instrumental Use": The world has a transparent light, and there are inscriptions on the back. In order to learn from the sunlight, the back text and the two crosses are all transparent on the wall of the house, and they are clear. People have the original reason, to say that when the casting is thin, the first cold, but the back of the text is poor, and then cold and copper shrinks, although the text is in the back, and the face is faintly traced, so it appears in the light. Looking at it, it is true. However, the Yu family has three jians, and sees that his family has a collection, all of them are the same, and the inscriptions in the literature and painting are not different, and the shape is very ancient. Only this one is as transparent, and other thin ones cannot be transparent. The ancients had their own skills.

I just say this to feel the wisdom of our ancient Chinese people, the Shanghai History Museum has two Western Han Dynasty mirrors
