But how do I explain this conclusion to an ancient man, King Han? This can be related to chemistry, physics, projection, video and other terms that modern people understand. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info What should I say so that he will believe it? Wu Wu was in trouble in her heart.

"If he doesn't come up with an ingenious way to make King Han understand from his heart, he will probably be annoyed and angry. On the contrary, if I let the King of Han understand the secret, not only will I admire myself, but the King of Han will definitely admire me so much, after all, this is a high-tech that their ancient people have never seen. ”

"What to do? Travel back in time to get a DVD player? Wu Wu had this thought in her heart.

She remembered the agarwood bed that had once allowed her to travel back in time to modern times and steal 10 bottles of tetracycline tablets.

She didn't hold out hope, but she managed to sleep in that bed.

She tried to meditate many times.

I closed my eyes and woke up to find that I was still in that bed.

It doesn't seem to be a problem with the bed, if she wants to successfully cross back, it may have something to do with something she hasn't yet understood.

Now, she had to think about how to explain the scientific principles of this haunted incident on the red palace wall to King Han. Suddenly, when Wu Wu was in distress, the next day was just dawning, she suddenly heard someone knocking on the door outside the window.

When she opened it, it was actually Zi Yan, the personal maid next to Concubine Wei!

"Sister, I specially came to remind you, in half a month is the birthday of Concubine Wei's mother, people in the house say that my sister is the most ice and snow smart, I am afraid that my sister will not know and forget to give a festival gift, and the mother will be unhappy."

"Thank you sister for reminding me, I must remember."

Wu Wu was about to make tea for Zi Yan, but Zi Yan slipped away like a thief.

"It's weird, this Zi Yan, since I entered the palace, seems to have a good eye for me and treats me well, but after all, she is Concubine Wei's personal maid, she came to remind me today, is it kind or fake?"

Wu Wu was afraid.

She didn't dare to trust someone so easily.

When she entered Daming Palace, she was also like sisters with Furui, but in the end, the truth was so cruel.

No one will be nice to you for no reason, this is the blood lesson that Wu Wu got from her relationship with Fleur.

However, she secretly inquired, and it would indeed be the 2nd birthday of the youngest son of King Han in a while.

It seems that Zi Yan didn't lie to her about this.

"I have to give Xiao Shizi a birthday party that doesn't look like a face, so that Concubine Wei can completely resolve her resentment against me."

"At the same time, this birthday party also has a purpose, so that King Han can understand the scientific principle of the 'palace wall haunting' incident that night."

"By the way, this can also let the suffering old butler Cui Laifu clear himself from suspicion. Then Cui Laifu will definitely thank me in the future, so that I finally have a confidant in the palace. ”

Wu Wu suddenly had a flash of inspiration in her heart, and a perfect plan of "killing three birds with one stone" was brewing in her heart.

Wu Wu Meimei has been planning for a while, and the prototype of a birthday has been completed in her heart.

But this plan can't be completed by her alone.

I'm afraid it will have to rely on Zi Yan and Prince Wen Hara's secret help to make it happen.

The birthday banquet planned by Wu Wu is to take a photo of Xiao Shizi in front of Zhu Gaoxu, the king of the Han Dynasty.

The camera was invented in 1839, when France's Daguerre made the first practical daguerreotype camera.

It is now the eighteenth year of Yongle, 1420 AD, and there are still more than 400 years before the invention of the camera.

Taking a picture of someone with a camera and preserving it was impossible to do it with the level of technology in the world at the time.

However, it is impossible to store it for a long time, so it is enough to image it for a short time.

As long as you can explain the principle of camera imaging to the king of Han and explain to him the scientific principle of the "haunted incident of the palace wall", everything will be easy.

As early as the 13th century, the diligent Europeans appeared in the dark box made of pinhole imaging, and people walked into the camera obsca to watch the image or depict the scene.

It seems that Wu Wu now has to make a sealed box with a small hole on one side, through which the outside of the box will form an upside-down image on the inner wall of the completely dark box.

This is supposed to be the earliest form of the Chinese camera. Wu Wu entrusted this glorious task to herself.

Just do what she said, Wu Wu locked herself in the dormitory, and instructed the little girl Snow Goose: "From today on, any visitor who comes will say that I am not available." ”

After saying that, he locked himself in the house and began to make the legendary camera obscura.

It took three days and three nights, and after the camera obsca was made, Wu Wu put her head into the small hole in the camera obsca and took a look.

No, the image is too blurry.

Wu Wu suddenly remembered that in 1550, Cardano of Italy placed the biconvex lens in the original pinhole position, and the effect of the image was brighter and clearer than that of the camera obscura.

In order to make the image clearer, a magnifying glass must be placed in the small hole of the camera obscura.

I'm afraid I can only ask Prince Wenhala for help.

Just thinking about it, Prince Wen Hara suddenly came, really saying that Cao Cao Cao had arrived.

"Daughter-in-law, what are you doing hiding in your Shaoguang room these days? I've been stopped by your little girl Snow Goose on several visits! Didn't we catch a stonefish for you to eat during this time, so you ignored us? ”

"Where, let me tell you the truth, I actually hope that the fish can be ugly after eating it, and make me more beautiful, who knows, it doesn't work." Wu Wu has given up her face now anyway.

"Well, Xueba, it depends on strength." Wu Wu comforted herself in her heart and said.

"Really? How do I think you've become prettier? ”

Prince Wen Hara quickly glanced at Wu Wu, and there was a light of surprise in his eyes, "I think my sister-in-law has really become beautiful." In particular, the skin has become smoother and more delicate than before. ”

Wu Wu was overjoyed: "Really? You're not comforting me, are you? Prince, I am preparing a secret gift for the prince and the king of Han, but I need your help. ”

"As long as I can do it, I will help to the end."

Prince Wenhala said righteously, but there was an imperceptible disappointment in his heart.

"I'd like to get you a magnifying glass!"

Wu Wu finally spoke.

"Magnifying glass. You have it in China. Sister-in-law is a jack of all trades, why can't she remember it at this time? ”

Prince Wenhala smiled.

Wu Wu suddenly remembered that it was recorded in the Italian book of Marco Polo that as early as 1260 A.D., there was a scene of old Chinese people wearing glasses to read small characters.

At that time, glasses were expensive to cost, so they were used as a symbol of status. It is said that there is a record of a squire exchanging the price of a horse for a pair of glasses. (To be continued.) )
