Just when Mo Fan was looking at it, a burst of fragrance suddenly came over, and another waiter not far away said: "Dear fellow villagers, this is our store's secret perfume. Just drop one drop, and the house will be filled with fragrance immediately. Everyone, smell this fragrance.

How fragrant it is.”

Mo Fan walked closer and took a deep breath. The fragrance was refreshing. This perfume is also a good thing. He asked: "How much does a bottle of this perfume cost?"

"This scholar only needs 80 yuan to buy a whole bottle."

"80 Guan! So expensive!" Mo Fan said, "But I am not a scholar, I am a scholar."

"It turns out it's Master Juren. I'm so disrespectful." The waiter was shocked. This scholar had actually obtained the title of Juren at such a young age. It seemed like he had a bright future.

The clerk immediately took out a book from behind the counter and said: "Master Juren, please buy this copybook. This is our store's secret water-written copybook. You can use a clean brush dipped in water to write directly on it, and the water will become

It has to be like an ink mark, just like what is written in ink. As long as it dries, it can be reapplied with water again."

The waiter scratched his head and said: "In the boss's words, what is this called... By the way, it's called low-carbon environmental protection. It's most suitable for a distinguished master like you. The boss said this calligraphy is still very famous, what's it called..."

He couldn't remember the name at the moment.

Mo Fan pointed to the copybook and said: "It's "Duobao Pagoda Stele". Yan Zhenqing's post is of course famous. Have you heard of Yan Jinliu Gu?" He looked at the waiter's dumbfounded look and didn't know what to answer. He felt that he was playing the piano to a cow and no longer

Continuing the topic, he asked, "Can ink stains really appear when writing with clear water?"

"Of course you can!" The clerk put away the magnifying glass. Anyway, this thing couldn't be sold for a while. There were many people looking at it, but not many people could afford the price. Seeing that the Juren master in front of him was a wealthy owner, the clerk turned around.

Highly recommend water writing posts and blank water writing cloths.

The clerk took out a new writing brush and a bowl of water, handed the writing brush to Mo Fan, "Master Ju Ren, you try it!"

Mo Fan took the brush, poured some water into it, and asked doubtfully: "Is this how you write?"

The guy nodded and said, "Just write it like this!"

As soon as the tip of the pen touched the water writing cloth, the clear water actually showed ink marks on it. Mo Fan was amazed: "You can really write with clear water! Who is your boss? You are really a new generation who can make these magical things. This water writing

How much does it cost?”

"With only 30 yuan, you can buy this water-based writing post." According to Li Hao, the clerk added words like "only" and "only" before each quotation to give people a sense of great value for money.

feel.

"Interesting, I bought it."

Although I spent another 30 yuan, after all, I was buying things related to calligraphy, and I didn’t expect my father to say anything.

Mo Fan asked the bookboy to pay, and then asked: "The things in your store are so expensive, I don't know what is the most expensive."

The clerk pointed to the upper floor and said: "The most expensive thing is the telescope on the second floor, which costs 8,000 pieces. With that thing, you can see things in the distance as if they are in front of you."

"So magical? I want to see it." Mo Fan walked towards the second floor.

There were also many strange and novel goods on the second floor. Mo Fan asked about it and came to a position near the window. He saw a cylindrical object placed on a tripod. The object was completely black, with one end big and one thin.

The big end is facing the window.

A handsomely dressed young man stood next to the object, moved his eyes to the very thin end, and looked inside. As he looked, he praised: "The people a few streets away seem to be right in front of me.

Same. Wow, that little lady at the government office is very pretty."

Mo Fan stood on tiptoe and looked out the window. There were a few small black spots in the distance. It was so far away that he couldn't tell whether those people were male or female. Can he still see their faces clearly? He said to the clerk: "Yes.

Let me take a look."

The clerk said: "This telescope is worth 8,000 yuan. It is a very valuable item. It was not allowed to try it out. But in order to let the guests understand the goods, we allowed them to pay 100 yuan and then try it out for one stick of incense. If the guest finally decides not to

If you buy it, the 100 yuan will not be returned."

Are you charging money for just looking at it? Mo Fan couldn't help but sigh, the owner of this rare treasure pavilion is so good at making money.

Mo Fan's curiosity had been aroused, so he naturally didn't take the mere 100 coins in his eyes, and immediately asked the bookboy to pay again.

Li Hao set an extremely high price for the high-power telescope, not because he wanted to sell it, but because he had made up his mind early in the morning to charge customers who would try it out. It was 100 yuan per person. If there were more people watching, the fee would be quite high.

considerable.

It was Mo Fan's turn. The waiter lit a new incense stick and asked Mo Fan to come forward and take a look. Mo Fan looked closer and saw pedestrians several streets away. Mo Fan looked away from the telescope and saw that there were

People are like little black dots, but through a telescope, their facial features can be seen clearly.

"Telescope, this is a good name, it really can see far away."

After trying out the telescope, Mo Fan walked around the store again and marveled at everything in the store.

The goods here are all kinds of strange, everything is something he has never seen or heard of, and there are even some things he has never dreamed of. Everything is so amazing!

There is a thing called a watch, which can be used to keep time after being wound. If you look at where the hands go, you can know the precise time. It is much more accurate than a water leakage.

There is something called sunglasses. After wearing those sunglasses, the color of the sky changes throughout the day. The sun is not dazzling at all. The surrounding light is adjusted and the eyes are very comfortable. There is also something called reading glasses, which are said to be specially made for people.

They are worn by older people. Mo Fan wants to let his father try them out some other day. These reading glasses might be suitable for them.

There is a thing called shower gel. It is said that after taking a bath with it, the whole body feels refreshed. Although Mo Fan has never tried it, he is already full of confidence in this rare treasure pavilion. This thing must have its magic.

Mo Fan's eyes were opened. Just when he was in awe, he heard a voice: "Just outside the store, I seemed to hear my brother saying that he wanted to smash my sign?"

Mo Fan turned around and saw two people, an old man and a young man, standing behind him. The young man among them asked: "I wonder what's wrong with the shop's sign that makes me want to smash it and then kill it?"

A look of surprise flashed across Mo Fan's face, and then his face turned slightly red. He clasped his fists and said, "My little brother Mo Fan, I am a literary practitioner with cursive characters. I haven't asked my brother for his surname."

Li Hao also followed his example and said politely: "I'm Li Hao."

"What is the relationship between Brother Li and this rare treasure pavilion?"

"This shop is opened by me."

"It turns out that Brother Li is the owner of the Qizhenbao Pavilion. I'm so disrespectful. The so-called smashing of the signboard is just a temporary blunder. Every item in your store can be called a peerless treasure. The signboard of the Qizhenbao Pavilion is real.

Well deserved. I spoke so freely and hereby apologize to Brother Ziran!" After saying this, Mo Fan bowed deeply. Businessmen in the Song Dynasty took their signs very seriously, so the idea of ​​smashing them was indeed a bit excessive.

Li Hao just said it as a joke before, and he didn't want Mo Fan to apologize openly. This person is someone he can make friends with, and he is a bit curious about the scholars of this era. He waved his hand and said: "Forget it, Brother Mo is too

It's an unintentional mistake. It's fate that I can meet Brother Mo today. It's better to meet by chance than to meet him. Why don't I serve as a host and invite Brother Mo to have a few drinks at Taibai Tower opposite."

Mo Fan said happily: "That's great, I was about to ask Brother Li for advice. But let me take the lead. Just treat it as an apology for what I said just now, otherwise I will feel bad."

"Serious words, serious words." Li Haowei pondered, then turned to the housekeeper Ding Fu and whispered a few words. Ding Fu nodded repeatedly and went to get a box.

Li Hao took the box and handed it to Mo Fan, saying: "Since Brother Mo insists on treating us, I'm going to bother you. I think Brother Mo must be good at calligraphy and painting. This box is for mixing paints for painting.

Dissolve it with water and it can be used. I gave this little thing to Brother Mo." This box of art paints, the box and the trademark text of each paint inside have been scraped off with a razor blade.

"This...Brother Li, everything in your store is a rare treasure in the world. How dare I accept such an expensive gift?"

Li Hao laughed and said: "This thing is not worth much. It is just paint for painting. The painting is valuable. Then I will have the audacity to ask Brother Mo for one."

Mo Fan is an open-minded person. He hesitated for a moment and then took the box. "In that case, thank you very much, Brother Li. Then I will bring my paintings to Brother Li for advice. However, my paintings are not worthy of elegance.

But my sister-in-law has quite a lot of experience in painting."

While chatting, the two of them left the Treasure Pavilion and went to the Taibai Building diagonally across the street, where they found a seat separated by a screen and sat down.

Mo Fan ordered more than a dozen side dishes and asked the waiter to serve two bottles of wine. Mo Fan's boy stepped forward and filled two glasses of wine, then stepped aside and stood to wait.

The two toasted each other with two glasses of wine, and Mo Fan finally couldn't help but ask: "Brother Li, the water written on cloth is so magical, I can't understand it. Why does clear water turn into ink when written on it? And why is it so cold?

The ink stain will disappear after it dries, and can it be used again and again?”

"Uh," Li Hao really didn't know the principle of water writing on cloth. He secretly complained in his heart, "I'm not a blue cat who can answer a hundred thousand whys."

Li Hao shook his head and said: "This is made by the most skilled craftsmen overseas. The specific production method is a secret passed down from other people's families, and I don't know it either."

"Oh!" Mo Fan felt slightly disappointed, and then asked: "Then why can things seen through a magnifying glass be much larger than before?"

Li Hao knows the principle of convex lenses very well. After all, he is a science and engineering student at a prestigious university. Since this native is so curious, let's explain it to him, but I don't know how much he can understand. "We see things because of light.

This magnifying glass is made of a transparent substance called glass, and light will be refracted when passing through the glass..."

Li Hao explained the principle of convex lenses in detail, and when he talked about something Mo Fan didn't understand, he asked the restaurant waiter to get some water and draw a simple diagram of light refraction on the water cloth on the spot.

Li Hao added at the end: "Refraction phenomenon is very common. I don't know if Brother Mo has ever speared a fish. After the light is refracted, the actual position of the fish is actually lower than what you see. When spearing a fish, you have to spear it slightly lower.

Only when you go there can you spear the fish. Another example is when you insert a chopstick diagonally into the water, it looks like the chopstick is bent." Then he drew another picture of the fish refracted by the water surface.

To Li Hao's surprise, Mo Fan was very receptive. After Li Hao's in-depth explanation, he was able to understand it. Because of this, Mo Fan stared at Li Hao with eyes like goldfish, as if

I saw a flower suddenly appeared on Li Hao's face.

The shock in Mo Fan's heart was unparalleled. A common phenomenon in life could be extended to include such rich truths. The knowledge of the man in front of him was really as deep as the ocean.

Mo Fan looked at the pattern of the water-written cloth gradually fading, and said thoughtfully: "Brother Li seems to have not finished what he said just now. There must be more truth here. Please explain it to me, brother Li."

Li Hao looked back, do you really think that I am your physics teacher? How many optical lessons will I have to give you? I can go on, but do you understand if I go deeper, such as using Snell's formula to calculate

The index of refraction involves the ratio of the sine of the angle of incidence to the angle of refraction. You, a native, don't understand trigonometric functions at all. If you understand it, you can't understand it unless the sun rises from the west.
