Ancient Chinese spectacles were large oval in shape, with lenses made of crystal, quartz, topaz or amethyst, set in a frame made of tortoise shell, with copper feet attached to the sideburns, or tied to the ears with strings, or directly attached to the hat. Pen, fun, pavilion www. biquge。 info

"My father used to have a pair of purple jade glasses that your Emperor Ming gave me, why did you forget it? If you need it, I'll still have those glasses with me after my father dies. ”

After Prince Wenhala finished speaking, he took out a pair of purple jade glasses in a beautiful box from his close-fitting sleeves, and said with a little reluctance: "These glasses are the only thing I have in mind for my father." ”

"That'...... Prince, am I embarrassed for you? ”

"It's okay, as long as you take it to do something meaningful, I'm sure my father's spirit in heaven will be grateful. My father was very friendly to China during his lifetime. ”

Prince Wenhala said generously.

Wu Wu's heart warmed.

With the relics that Prince Wen Hara left behind the East King, the purple jade glasses took out a small lens and handed it to Wu Wu.

It took Wu a few more days to grind the lenses to a smaller size before they were installed on the camera obscura.

On the day of Xiao Shizi's birthday, the stars held the moon, and everyone took out the treasures at the bottom of the box, pleasing King Han and Princess Han.

Wu Wu suddenly took out a dark box covered with a black cloth, and said mysteriously to King Han, "Lord Wang, I want to conjure a magic trick for you, I can transform Xiao Shizi into this box, do you believe it?" ”

King Han, who was slightly drunk, looked at the little dark box and pursed his mouth, "Girl, they all say that you are smart, but I am not stupid, you fool me so much?" ”

Wei Rujin and the two side concubines on the side also expressed their disbelief in unison.

"Lord Wang, then let's make a bet, if I can turn Xiao Shizi into this small box, you will agree to my request. But this requires me not to mention it now, and I will cash it in when I need it in the future, okay? ”

King Han was happy in his heart, and the two side concubines and Concubine Wei were coaxing on the side, waiting to see Wu Wu's joke, so King Han said loudly: "Okay, this king promises you, you can make a request to this king in the future." ”

"Lord Wang, now, please Xiao Shizi stand on the stage."

While speaking, Zi Yan had already brought Xiao Shizi to the stage dozens of meters away, Wu Yan pointed the camera obscura in the direction of Xiao Shizi, and said with a smile: "Lord Wang, please take a look." ”

At this time, King Han drunkenly poked his head into the dark box wrapped in black cloth to take a look, ah, the side walls on both sides of the box, sure enough, there was a lively little world!

"It's strange, Jin'er, come and see, is this king drinking too much and his eyes are spent?"

King Han hurriedly asked Wei Rujin to put his head into the camera obscura, and after Wei Rujin put his head in, he also had a stunned expression.

After the two side concubines saw it, they were also so shocked that their mouths opened into an "O-shape".

"Monsters, monsters, monsters, lords!"

The three ancient women who had never seen the world pointed at Wu Wu in unison and said, "Lord Wang, quickly arrest her for me." This man must be a demon from somewhere! ”

Especially Wei Rujin, she cried even more: "Lord Wang, this demon girl can hook souls and collect the soul of our little son in that box." ”

After speaking, Wei Rujin went to the stage like crazy to snatch Xiao Shizi, and hugged him tightly in his arms, for fear that he would fly.

Wu Wu didn't expect that the originally scheduled surprise birthday banquet would suddenly change her painting style and put herself in such an embarrassing situation.

At this time, King Han's face also changed a little, probably he had never seen such a strange phenomenon, he couldn't understand the situation at that time, and felt that Wu Wu in front of him was really a little weird.

"The girl is young, is she really a warlock or does she know some kind of magic? Hurry up and recruit from the truth, or I won't be spared. King Han hesitated, but still lowered his face and shouted to Wu Wu.

"Lord Wang, look, Xiao Shizi is doing well on the stage. If I want to do something to Xiao Shizi, why would I take the initiative to invite you to come and see this box? ”

"What's the point?" Han Wang's voice was a little quieter, and his tone was softer.

"Lord Wang, in fact, what your sister-in-law showed you today is just our ancestor's 'small hole imaging'."

Speaking of this, Wu Wu confidently hugged her fists to the guests and said:

"As early as more than 400 years B.C., China's book "Book of Ink" recorded in detail the straight advance of light, the reflection of light, and the imaging phenomenon of plane mirrors, concave mirrors, and convex mirrors. In the Song Dynasty, in the book "Mengxi Bi Tan" written by Shen Kuo, the principle of "small hole imaging box" was also described in detail. ”

At this time, King Han still had an expression that seemed to understand or not, but her two side concubines, Xu Miao and Bai Feiyan, had already shown a happy and convincing expression.

Wu Wu knew that these two talented concubines had already figured out the principle, so she walked up to the two side concubines, bowed slightly, and said with a smile: "Lord Wang, these two side concubines are famous for 'Nanxu and Beiyan', so they must have heard of Mr. Shen's "Mengxi Writings"? ”

Xu Miao and Bai Feiyan were both slightly ashamed to salute Wu Wu, and whispered, "Let the girl smile." ”

At this time, when King Han saw the expressions of the two concubines, his face had eased a lot.

Wu Wu knelt in front of King Han again and whispered: "Lord, I have worked hard to plan this birthday party for Xiao Shizi today, on the one hand, to express my congratulations to Concubine Wei's mother and Xiao Shizi, and on the other hand, I want to give back the old housekeeper Cui Laifu a clean slate. ”

The expression on King Han's face was even more surprised and inexplicable, he seemed to think of something, but he still had an incredible expression and said: "Could it be that this dark box has something to do with the 'palace haunting' incident that night?" ”

"Exactly!" Wu Wu called the King of Han to the side, and whispered to him to explain to him hundreds of years ago during the Five Dynasties period, strong lightning will conduct electrical energy down, and it happened that there was a palace maid passing by that night, so at this time the red palace wall is equivalent to the function of a video tape, and the shadow of the palace maid was recorded in the palace wall.

When he and Wu Wu met in the small kitchen that night, it was a thunderstorm night, and lightning appeared, and the shadow of the palace maid who was recorded hundreds of years ago was transmitted again.

"You mean, this red palace wall is like this camera obscrama you made today, which can record other people's images?"

King Han seemed to have a sudden realization, but he also seemed to be full of doubts.

"Exactly, the prince is wise! Under the action of lightning, the red palace wall contains a special substance, just like the camera obsca I made today. It has the function of recording video. ”

Speaking of this, Wu Wu said with some regret: "It's a pity that my camera obsca is not good enough, I can only let you see the image, but I can't save the image for a long time." ”

Thinking of this, Wu Wu felt that if she could invent a camera in the Ming Dynasty and take pictures of these ancient things, it would be amazing. (To be continued.) )
