Mo Fan was seeing it, and suddenly a burst of fragrance came over, and another guy not far away said: "Fellow villagers, this is the secret perfume of our store." Just drop a drop and the fragrance will fill the house immediately. Let's smell it, how fragrant this fragrance is. ”

Mo Fan approached and took a deep breath, a fresh fragrance refreshed people's hearts, this perfume is also a good thing, he asked, "How much is a bottle of this perfume?" ”

"This talented man can buy a whole bottle for only 80 yuan."

"80 times! It's so expensive! Mo Fan said, "But I'm not a showman, I'm a lifter." ”

"It turned out to be a man, and the little one was disrespectful." The guy was surprised, this scholar was so young, he actually won the examination to make a name for himself, and it seems that he has an unlimited future.

The guy immediately took out a book from behind the counter and said, "Master Juren, you can buy this copybook." This is our secret water writing notebook, with a clean brush to boil water, you can write directly on it, the water becomes like ink, just like the ink is written. As long as it is dried, you can repeat the water and write. ”

The guy scratched his head and said, "In the words of the owner, what is this called...... That's right, it's called low-carbon environmental protection. It is most suitable for a man with status like you. The proprietor said that this calligraphy is still very famous, what is the name...... "He couldn't remember the name for a while."

Mo Fan pointed to the post and said: "It's "Duobao Pagoda Tablet", Yan Zhenqing's post, of course it's famous, have you heard of Yan Muscle and Willow Bone?" He looked at the young man's dumbfounded expression, and felt that he had played the piano to the cow, so he stopped continuing the topic, and asked, "Can you really write with clear water to show ink?" ”

"Absolutely!" Guy, put away the magnifying glass, anyway, this toy can't be sold for a while, there are many people who see it, but not many people can afford it. Seeing that the old man in front of him was a rich man, this guy turned to recommend water writing posts and blank water writing cloths.

The man took out a new brush and a bowl of water, and handed the brush to Mo Fan, "Master Juren, you try!" ”

Mo Fan took the brush, soaked it in clean water, and said suspiciously: "Just write like this?" ”

The guy nodded, "That's it!" ”

As soon as the tip of the pen touched the water, the ink appeared on it. Mo Fan was amazed: "You can really write with clear water!" Who are your owners? To be able to make these magical things is really a generation of aliens. How much does this water post? ”

"It only takes 30 pieces to buy this repeated use of water to write posts." According to what Li Hao said, adding words like "only" and "only" before each quotation gives people a sense of value for money.

"Interesting, I bought it."

It took another 30 times, but after all, it was about calligraphy, and I don't think my father would say anything.

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

The guy pointed upstairs and said, "The most expensive is the telescope on the second floor, 8,000 yuan." Look at things in the distance with that play, just like what is in front of you. ”

"So amazing? Let's see. Mo Fan stepped forward to the second floor.

There are also a lot of new and strange goods on the second floor, Mo Fan asked, and came to the position near the window. I saw a cylindrical object placed on the tripod, the object was completely black, one end was large, the other was thin, and the big end was facing the window.

A well-dressed young man stood beside the object, and his eyes were drawn to the very thin end, and he looked inside. As he watched, he also sighed and praised: "The people a few streets away look like they are right in front of me." Wow, that little lady in the direction of the government is very beautiful. ”

Mo Fan tiptoed to look out of the window, there were a few small black spots in the distance, so far away, those people couldn't tell whether they were men or women, and they could still see their faces clearly? He said to the guy, "Let me take a look too." ”

The guy said: "This telescope is worth 8,000 yuan, it is a very valuable item, and it is not allowed to try it, but in order to let the guests understand the goods, it is allowed to pay 100 yuan, and then try to see a stick of incense." If the guest finally decides not to buy, the 100 will not be returned. ”

Take a look at it and also collect money? Mo Fan couldn't help but sigh with emotion, the owner of this Rare Treasure Pavilion was too good at making money.

Mo Fan's curiosity had been aroused, and he naturally didn't pay attention to the mere 100 yuan, and immediately asked the scholar to pay again.

Li Hao set a high price for the high-powered telescope, not wanting to sell it at all, but to pay attention early in the morning and charge the guests who tried it. 100 Wen per person, if there are more people watching, this fee is also quite considerable.

When it was Mo Fan's turn, the man lit a new incense stick and let Mo Fan come forward to watch. Mo Fan's eyes came forward to look, and he saw pedestrians several streets away. Mo Fan left the telescope and took a look, the people there were all small black dots, but in the telescope, the facial features and physiognomy could be seen clearly.

"Telescope, that's a good name, and it's really far away."

After trying out the binoculars, Mo Fan walked around the store again, marveling at everything in the store.

The goods here were strange, and everything was something he had never seen or heard of, and there were even things he could not have dreamed of. It's all amazing!

There is a thing called a watch, which can be timed after winding, and you can know the exact time by looking at where the hands go, which is much more accurate than a water leak.

There is a thing called sunglasses, after those sunglasses are worn, the color of the sky changes all day, the sun is not dazzling at all, the surrounding light is adjusted, and the eyes are very comfortable. There is also a type called reading glasses, which is said to be worn exclusively for the elderly. Mo Fan wanted to let his father try it another day, and these reading glasses might be applicable.

There is a thing called body soap, and it is said that you can feel good when you take a bath. Although Mo Fan hadn't tried it, he was already full of confidence in this Rare Treasure Pavilion, and this thing must have its magic.

Mo Fan was an eye-opener, but just as he was amazed, he heard a voice: "Outside the store just now, I seemed to hear my brother say that he wanted to smash my signboard?" ”

Mo Fan turned his head and saw an old man and a young man standing behind him, and the young man asked, "I don't know what's wrong with the signboard of the small shop, so that my brother will smash it quickly?" ”

The look of surprise on Mo Fan's face flashed, and then his face flushed slightly, and he hugged his fists and said: "Junior brother Mo Fan, cursive character Wenxiu, I didn't ask my brother Taigao's surname." ”

Li Hao also followed his example, and Wen Crepe said: "Under Li Hao." ”

"What is the relationship between Brother Li and this Rare Treasure Pavilion?"

"That's where this store opened."

"It turns out that Brother Li is the proprietor of the Rare Treasure Pavilion, and he is disrespectful. The so-called smashing the signboard is just a momentary mistake of the little brother, every item in your store can be called a peerless treasure, and the signboard of the Treasure Pavilion is well deserved. The little brother is open-mouthed, and I apologize to Brother Ziran here! As he spoke, Mo Fan took a deep breath. The merchants of the Song Dynasty attached great importance to signboards, and the idea of smashing signboards was indeed a bit excessive.

Li Hao was just a joke before, he didn't want this Mo Fan to apologize frankly, this person could make friends, and he was a little curious about the scholars of this era, he waved his hand and said: "Forget it, Brother Mo is also an unintentional mistake." Today, it is also fate to be able to meet Brother Mo, it is better to meet by chance, it is better for me to be the east, please Brother Mo to the opposite Taibai Building to drink a few cups. ”

Mo Fanxi said: "That's great, I'm about to ask Brother Li for advice." But it's better for the younger brother to make the east, just as he made amends for what he said just now, otherwise the younger brother will not go. ”

"It's serious, it's serious." Li Hao groaned slightly, turned his head and whispered a few words to the housekeeper Ding Fu, Ding Fu nodded again and again, and went to get a box.

Li Hao took the box and handed it to Mo Fan, and said, "Since Brother Mo insists on having a treat, then the little brother will bother." I think Brother Mo must be good at calligraphy and painting, this box is a toning pigment for painting, and it can be used when it is melted with water. This little toy was given to Brother Mo. "This box of art paint, the box and the trademark text of each paint inside have been scraped off with a razor blade.

"This ...... Brother Li, anything in your store is a rare treasure in the world, how dare my little brother accept such a valuable gift. ”

Li Hao smiled and said: "This thing is not worth anything, it is just a paint for painting, and the painting is valuable. ”

Mo Fan is an open-minded person, hesitated slightly, and took the box. "In that case, thank you Brother Li. At that time, the younger brother will bring the painting to ask Brother Li for advice. However, the younger brother's painting is difficult to get into the elegant hall, but the younger sister has a lot of experience in painting. ”

While chatting, the two walked out of the Treasure Pavilion, and together they came to the Taibai Building diagonally across the street, and found a private seat separated by a screen and sat down.

Mo Fan ordered more than a dozen side dishes and asked the guy to serve two pots of wine. Mo Fan's scholar stepped forward and poured two glasses of wine, then retreated to the side and stood and waited.

The two exchanged two glasses of wine, and Mo Fan finally couldn't help but ask: "Brother Li, that water writing cloth is so amazing, the younger brother is puzzled." Why does Qing Shui turn into ink when it is written? And why does the ink disappear after it dries, and it can be used repeatedly? ”

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

Li Hao shook his head and said: "This is made by the most brilliant craftsman overseas, and the specific production method is a secret of other people's families, and the younger brother doesn't know." ”

"Oh!" Mo Fan felt slightly disappointed, and then asked: "Why can the magnifying glass be so big than the original to see things?" ”

The principle of the convex lens Li Hao is very clear, after all, he is a science and engineering student of a famous university, since this turtle is so curious, he will explain it to him, but I don't know how much he can understand. "We see everything because there's light. The magnifying glass is made of a transparent substance called glass, and light is refracted through the glass......"

Li Hao told the principle of the convex lens, and when it came to Mo Fan's incomprehension, he also asked the restaurant guy to fetch clear water, and drew a simple diagram of light refraction on the water canvas on the spot.

Li Hao said at the end: "The refraction phenomenon is very common, I don't know if Brother Mo has forked fish." The light is refracted and the actual position of the fish is actually lower than what you see, and you have to fork the fish slightly below to get the fish in the middle of the fish. Another example is when you stick a chopstick diagonally into the water, it looks like the chopsticks are bent. As he spoke, he drew a picture of a fish refracted through the water.

To Li Hao's surprise, this Mo Fan was very receptive, and after Li Hao's in-depth explanation, he could actually understand it. Because of this, Mo Fan puffed out his goldfish-like eyes and glared at Li Hao, as if he saw Li Hao suddenly have an extra flower on his face.

The shock in Mo Fan's heart was incomparable, the phenomena that he was accustomed to in life contained such a rich truth, and the knowledge of the person in front of him was really as deep as the sea.

Mo Fan looked at the fading pattern of the water writing cloth, and said thoughtfully: "Brother Li seems to have said unfinished just now, presumably there is more truth here, please Brother Li will explain it for the foolish brother." ”

Li Hao's eyes were reversed, are you really your physics teacher? How many optics lessons will you take on a volunteer? I could go on and on, but if you go deeper, do you understand, for example, using Snell's formula to calculate the refractive index, which involves the ratio of the angle of incidence, the angle of refraction of the sinusoid, you are a turtle, you don't understand trigonometric functions at all, if you can understand it, unless the sun rises in the west.

Li Hao waved his hand and said: "Ge Wu is all kinds of things, and I only understand the skin and man, and I can't extend it anymore, and these studies are too boring." Let's talk about something else. ”
