A treasure-appraisal maniac

In the Panjiayuan Wen miscellaneous entertainment area, Lu Fei followed the flow of people while looking left and right.

After walking around for a while, a stall on the right caught Lu Fei's attention.

What aroused Lu Fei's interest was the size of this stall.

After coming in for a while, the stalls I saw were usually three or four meters long, but this stall was eight meters long, attracting many people to stop and watch.

Lu Fei squeezed in and saw clearly, my dear, this stall doesn't look like selling literature and entertainment, it's just wholesale!

The floor-to-ceiling stall is eight meters long and two meters wide.

All kinds of cultural toys were piled up into more than a dozen hills.

For example, bracelets, no matter what quality or specification, are all piled together, so you can choose whatever you want.

There are also pieces, whether they are made of jade, beeswax, or wood, as long as they are pieces, they are like a hill. .??.??

The worst thing is Wenwan Walnut.

Hundreds of walnuts were piled together, with prices clearly marked at eighty-one pairs.

They say they are sold in pairs, but all the walnuts are mixed together and there is no way to tell them apart.

If you want to ask the stall owner to help you choose, the stall owner will not wait at all, so you can only make enough food and clothing yourself.

Although the goods are arranged in a disorderly manner, it gives people a different visual impact and really attracts the attention of many people.

The stall owner was sitting on the horse in a majestic manner, with two large QR codes hanging around his neck, holding a large amount of cash in his hand, holding a cigarette diagonally in his mouth, and shouted loudly.

"Just pick whatever you want, it's a big sale after the stall is closed!"

"All goods have the purchase price. Whichever one you like, come to me and pay!"

"Boss, how much does this red sandalwood bracelet cost?"

"One hundred dollars!"

"Why is it so cheap? It can't be fake, right?"

"Aren't you talking nonsense?"

"If it really sells for a hundred, am I out of my mind?" the stall owner said with his lips curled up.

"It's really fake

Yeah, then I don’t want it. "

The man said, throwing the string of bracelets into the pile, and was about to get up and leave.

A middle-aged man next to him said with a smile.

"Nowadays, fake red sandalwood is so prevalent that you can't find two genuine ones in Panjiayuan."

"Other stalls sell dog meat with sheep's heads and kill people, but this stall owner is still quite honest."

"Besides, the goods he sells here are all high-quality imitations, and you'll definitely be able to show off by showing off."

"I think your string is pretty good. If you don't want it, I'll take it."

"Hey, this big brother is right!"

"In that case, I want it, and the boss will give you the money."

The middle-aged man's analysis made people around him think it was reasonable, and they immediately rushed to buy it.

Most of the items on the stall are C goods, and some are even D goods. Lu Fei's Jubao Pavilion also needs to buy handicrafts, and he has a certain understanding of the purchase price of these items.

None of the items in the entire stall cost more than ten yuan.

Some items are outrageously cheap, even per kilogram.

But the stall owner used such a weird business method, and there were two shills wading in the muddy water inside, which immediately caused a buying frenzy.

I have to say that this stall owner really has some business acumen.

"Boss, is this Luban box also for sale?"

Um?

Just as Lu Fei was about to leave, a young woman's voice came from the far left side of the eight-meter stall.

Lu Fei followed the sound and saw a young man and woman in their early twenties, holding a six centimeter square Luban box and asking the stall owner.

Lu Fei's eyelids jumped when he saw this Luban box.

The so-called Lu

Ban box refers to a specially constructed wooden box.

Luban box uses splicing technology, using several or even dozens of wooden blocks of different styles to be cleverly combined together.

There are wooden mechanisms in it, and once they are put together, they will undergo many changes.

If someone doesn't understand the structure, opening the box is as difficult as cracking the password of a bank vault, and is an almost impossible task.

Luban box originated in the Spring and Autumn Period. It is unknown whether it was created by Luban, but it does vividly embody the whimsical ideas and infinite wisdom of the craftsmen.

In the Song Dynasty, the craftsmanship of Luban boxes was once again sublimated. Not only were there more and more types and styles, but the mechanism design was even more superb and unimaginable.

In the eleventh year of Jiading in the Southern Song Dynasty, Xu Yan, a craftsman from Jiangnan, created the first coded Luban box and became famous all over the world.

The cryptex made by Xu Yan was not the cipher of the current cryptex.

Instead, a slide is set up in the internal mechanism of the box and locked with balls and circlips.

The internal slide structure is complex. Only in accordance with the established sequence can the balls slide smoothly into the mechanism and then contact the mechanism's secret lock to open the Luban box.

The password Xu Yan set was not the current Arabic numerals, but the Five Elements, or the Eight Diagrams, or something lofty and noble such as Heaven, Earth, Xuanhuang, etc.

At that time, ball machines included Luban boxes, which were almost the only choice for wealthy businessmen and powerful people to hide important items.

It is so safe to have a ball bearing Luban box to collect things.

To what extent is the insurance coverage?

Now there are three Xu Yan's ball machine Kuo Luban boxes in the National Museum. Masters from China, led by Master Kong Fanlong and his disciples, have been studying them for decades. Until now, none of them have been opened. Do you think they are awesome?

However, this is not the most awesome thing.

Although the Luban box designed by Xu Yan for the ball machine is clever, if you encounter someone with a bad temper, you would rather put it inside

If you don't want the things, you will fight to the death and violently demolish them, and it won't work in Ritian's agencies.

But there is a kind of Luban box that has no chance of death.

During the Qing Dynasty, there was a Guoji pawnshop in Jinan Prefecture, and the business was very good.

But in the late Qing Dynasty, the situation was turbulent and banditry was rampant across China.

As the hometown of thieves in Shandong, the "disaster" in Jinan Prefecture is even more serious.

When gangsters come out to pounce on the autumn wind, they must be targeting people with goods, so Guoji Pawnshop, which has considerable assets, has become a key target of gangsters.

At its worst, Guoji's pawnshop was visited four or five times a day, causing heavy losses.

In desperation, we had to close our doors.

The pawn shop could no longer be opened, and the Guo family was worried that gangsters would come to rob their home.

In this case, Guo Chong, a talented young man from the Guo family, invented a daily Luban box.

There are several complex channels inside this Luban box. Part of the mercury is injected into the channels, and atmospheric pressure is used to control the direction of the mercury and transmit the balls to unlock it.

This kind of design may not seem like much nowadays when science is advanced, but in the late Qing Dynasty more than a hundred years ago, this kind of design was simply out of date.

Even if someone breaks a Luban box like this in a hurry, 90% of the time he will accidentally inhale mercury and die from poisoning.

Unfortunately, Guo Chong only made six of these Luban boxes.

On the autumn night of the 29th year of Guangxu's reign, gangsters invaded Guo's house, killed and robbed them, and the young genius Guo Chong died on the spot.

The next day, Lu Fei, who happened to be passing by, heard the news and sneaked into Guo's house to clean the battlefield. No, it should be to survey the scene, and accidentally found the design drawings left by Guo Chong.

Unfortunately, not a single complete Luban box was seen.

But Lu Fei never expected to see a legendary Luban box at Panjiayuan's stall today.
