"Mr. Yang, do you do this deal?" Luo Xiaoqiao waited for him to calm down before he began to ask.

The apple trees on Daqing Mountain are early ripening, and many of them bear fruit in July and August, and according to Cai Fushan, who has been taking care of the fruit forest, they can ripen in a month.

Luo Xiaoqiao looked over one day and had a whim. I asked my subordinates to cut out some words on black paper and paste them, and told them to watch them regularly and not let them go.

In this way, this batch of fruits was even so precious that it was bagged before the rain, and finally lived up to her expectations, and this time it helped her a lot.

"Do!" Yang Yuannian straightened his mind, "How many princesses are there?" I want fifty, can I? ”

"Yes", Luo Xiaoqiao smiled, his own fruit forest is big, the old man is a birthday, this is a free way to publicize.

"Mr. Yang, what do you think about the tomb?" Luo Xiaoqiao climbed down the pole.

Yang Yuannian's face shook unconsciously, this Princess Jing is really good at picking the right time.

"Mr. Yang, as long as you agree that our railway will pass over there, the conditions will be driven by you." Luo Xiaoqiao is sincere.

She is not afraid of the other party's lion opening her mouth, to whom, what routines to use, this is not a greedy for money. If it's too much, they will change the route.

"Yes, according to what you said, find a master to repair a feng shui river..."

As soon as Yang Yuannian's words came out, Luo Xiaoqiao smiled: "Mr. Yang, thank you for your contribution to the Northland." ”

……

With the launch of Apple, the people of Xingcheng, especially the big families, are about to go crazy.

"Princess Jing's Zhuangzi is out again!" The streets are full of people talking to each other.

Even the middle seam of the Northland Times was advertised.

It's not that she is using her power for personal gain, but she pays advertising fees according to the market price.

Didn't you see that household Ge Zhengtong, has his face been much better recently? The advertising fee for this newspaper page alone brought him how many silver taels.

"Master, wife, the Wang family store is selling new products, shall we go and have a look?" A housekeeper came in and asked questions.

The lady in charge clenched her hands tightly, and she was about to scold the princess Jing to death in her heart.

Where did she get the idea? This year has not yet reached the end of the year, and the public high school has almost spent a year's budget.

But did you make her not buy it? Naturally, she was still unwilling, such good things were necessities, and it was hard to find anything, so how could she not buy them?

Several ladies were extremely conflicted, and asked their subordinates: "Do you know what it is?" ”

Madame thought to herself, it can't be some toilet paper, right? If there's another thing, they'll have to buy it.

"It's Apple, it's going crazy out there."

The ladies breathed a sigh of relief, and after a while, they remembered and asked, "What is there to grab for apples?" ”

"Madam, go in and take a look, the words on the apple are long!"

"What? How is this possible? Even the most calm old lady of the Cai family couldn't help it.

"Go out and buy me a few to see."

"Old lady, ten taels of silver each, how many do you want?"

"Shhhh Why is it so expensive? ”

"I heard that at this price, the good ones are almost sold out," the little guy continued.

"Go out and buy ten, let's cheer for the girl." Mrs. Cai said magnificently.

When the little guy came back, one by one, they couldn't sit still anymore, and even the barely maintained calmness on their faces showed a hint of cracking.

"Old lady, is this a "long life"? The eldest lady trembled her hands and touched and touched.

"Daddy! Scared the hell out of me! How can Apple write long words on its own?! Sun Yangbo's family naturally saw it.

He glanced at Chu Renyi in the crowd, and the two sides tacitly agreed, how could this be something that human beings could do?!

This woman will be a scourge!

……

Luo Xiaoqiao didn't expect that Xingcheng apples almost caused panic among the people, and he knew that Cai Fushan, a fruit farmer, came out to explain, and took people to Daqingshan to see it before it calmed down.

Although I know how to grow it, the effect of black paper is not good after all, and there are not many that can be sold in good condition.

The big families are about to go crazy.

The train "clicked" and took Luo Xiaoqiao back to Luojia Village.

Unexpectedly, as soon as I opened the car door, I saw the three elders waiting there.

After the third elder saw her, he rushed up excitedly: "Princess, come with me!" ”

"What's so urgent, Third Elder?"

After being together for so long, Luo Xiaoqiao has never seen him so excited.

That old face, full of red light, looked like it wanted to tremble excitedly.

"Princess, you go and see it, come with me!"

"Zisu, you go to King Jing's Mansion and say it, I'll be back later", Luo Xiaoqiao explained and followed him.

Feng Chenhao wanted to go back directly, but seeing their mysterious expressions, he couldn't help but follow.

The door of Tianji Pavilion was wide open, and countless pairs of eyes looked at the door.

"What's the matter?" Luo Xiaoqiao was a little confused.

"Look, princess!"

A young man named Gai Moqin walked up and handed him a copper plate.

"What's this?" Feng Chenhao leaned up, "Isn't it just a copper plate?" ”

Gai Moqin's mouth trembled with excitement, he was a group of people who followed the extraction of silver iodide and participated in the artificial rain last time.

Ever since he got back into play, he's been fascinated by this magical change. The three elders saw that he really liked him, and let him go.

The day before yesterday, he inadvertently put a chopstick on a copper plate coated with silver iodide, just when the little brother wanted to learn mercury to make a mirror, they forgot to cover the bottle when they left at night, yesterday morning, when they came back, they found that the shape of the chopsticks was printed on the plate.

On a whim, he tried something else, and found that the copper plate of silver iodide could be imaged, but it was gone as soon as the sun broke.

So I want Luo Xiaoqiao to help take a look, if... If they're right, then... Is it possible to draw a portrait with this?

Luo Xiaoqiao was almost surprised, is she a butterfly's wings that has opened the door to a new world?

The wisdom of the ancients is amazing!

Isn't this the imaging principle of the oldest cameras?

Luo Xiaoqiao circled around the plate for a long time, took the straw paper to write and draw, and then said to a few people, "It should be what you think." ”

Silver iodide is easy to be sensitive to light, and different things will leave shadows due to different light, but they are unstable, so they will decompose as soon as the sun shines.

The shadow of the chopsticks left behind is most likely because the mercury vapor sprayed up and the color was fixed, so it did not disappear.

"Princess, that's... That—" Gai Moqin flicked his hands and spun in circles excitedly.

"I'm a layman, but I think you can study it again. I remember reading a book by the Mo family, which said that the small hole was imaging, and I vaguely remember what it was called? Luo Xiaoqiao frowned and thought.

Gai Moqin and the three elders glanced at each other: "Jing." The light is like a ray, and the one who is below is high, and the one who is high is down..."

"Yes, yes", Luo Xiaoqiao listened to one head and two big.

"Let's try it, can you use the principle of small holes, don't we still have lenses? Give it a try and make a camera out. ”

"Camera?"

"It's something that can leave people and things behind."

"I can't help with this, I just think it's okay, chopsticks can leave a shadow, people can. We can also find a shadow puppet puppet player and study it together, they understand light," Luo Xiaoqiao said.

"Li Shaoweng!" Feng Chenhao, who had not spoken, shouted out with his eyes shining.

"Let Li Shaoweng come back, his ancestors are masters of shadow puppetry."

"Yes, yes, I followed him to Guzhi Mountain. Crow, you go and call him. ”

"Oh, Third Elder, you guys are really amazing."

When the three elders heard this, their beards were about to rise

Although Luo Xiaoqiao said that she didn't understand anything at all, she still explained the light propagation route of the lens before leaving, leaving a schematic diagram.

Then, she waved her sleeves, and under the expectant gaze of everyone, Shi Shiran left...

It's not her business field, it's not strong, and there are men waiting for her family.
