"Stones?"

"This thing in such a big treasure chest?!"

Look at the contents of the large treasure chest, and then look at the coins inside the small treasure chest.

The brows of everyone in Class 9 furrowed unconsciously, and their mood changed a little.

It's a little unbeautiful.

I feel like I've been completely busy all day.

Look at some of the coins that can't be called valuable, the ones that are so rusty that some of them are so rusty that you can't see any of them.

It's not as good as the copper coins of the Dragon Kingdom!

That thing can at least be used for gua sha when you're in a hurry.

What can you do with these coins? Is it just for viewing?!

Look at the large treasure chest that was supposed to give you high hopes!

Stone?!

Made, no wonder the whole box is so heavy!

As a bunch of pirates, why can't you put something of value in it?

Even if it's a few coins like the other chests?

In this way, you have not forgotten your job.

Right now?

Stone?

What the hell is going on!

After glancing back and forth a few times, Ah Wei sat on the deck dejectedly, and uttered the truest 'cry' from the bottom of his heart in a soulless voice:

"Come on... Can any of you tell me how much these six boxes are worth? ”

"emmm..., this thing might be priceless from a historical standpoint?" Li Cheng squinted his eyes and thought for a while: "But the main problem is that we don't know what the origin of these things is. ”

"And in terms of appearance and its potential ontological properties, this thing is estimated to be worth much even if it proves provenance."

"After all, you can't expect thousands of years of artifacts unearthed in this kind of place, don't you know the soil??"

"Besides, there shouldn't be many people who want to collect this thing..."

As he spoke, Li Cheng casually picked up a coin and played with it.

The first thing he felt about this coin was that it was a bad hand, and nothing special happened other than that.

"emmm, I guess it's not as valuable as the lock we smashed, that thing looks a little bigger, maybe it's still worth researching?"

After that, Li Cheng glanced at the rusted and unreadable locks on the ground.

"Then why are you still smashing?!" Aveden became angry.

Li Cheng shrugged helplessly: "If we don't smash it, we don't know what exactly is inside." ”

"It's better to break a lock than a chest."

"Although this box doesn't look like it needs to be destroyed."

After the words fell, Li Cheng looked at the big treasure chest again:

"As for this thing, seriously, it's probably even less valuable."

"Even if it's thousands of years old."

"But a stone is a stone... Worthless. ”

After speaking, Li Cheng threw the coin back into the treasure chest, and there was a muffled sound.

Then he clapped his hands:

"So, to sum up."

"The value of this thing to us is almost zero."

However, as soon as his words fell, Sun Hao's retorting voice came out:

"If you can't say that, how can you say it's worthless?"

"Doesn't it give us a perfect story?!"

As soon as Sun Hao spoke, Niu Pu immediately followed:

"Yes, yes, a perfect story!"

"We don't know exactly what happened, but there's definitely a story!"

"That's the best value for it!"

As he spoke, Niu Pu glanced at Sun Hao, and the two showed a little tacit understanding, and then said in unison:

"This is a fantasy adventure!"

"This is a biographical historical story!"

"Fantasy?!

”

"Biography?!

”

The words fell, and without waiting for others to release their opinions, the two immediately looked at each other, and they both looked at each other with a deep sense of horror.

"How can this be a biographical story? Do you understand romance! This is Sun Hao's question.

"Jokes, the facts are in front of you, you tell me fantasy, do you understand logic?!" This is the question raised by Niu Pu.

Immediately after that, the two shook their heads, and no one paid attention to anyone.

The previous small boat called 'tacit understanding' and 'fellow way' capsized when it was said to capsize...

Everyone in Class 9 looked at these two two goods expressionlessly, and a capital disdain appeared in their hearts.

They thought they must have been kicked in the head by a donkey.

We're talking about direct value, what potential value are you playing with?!

We're not on the same channel at all, okay?

Seeing this, Ren Yan couldn't hold back any longer, and laughed directly.

It wasn't until everyone's eyes were on him that he reluctantly stopped:

"Alright, don't look at me like that."

"Who made you all so unreliable?"

"You want to sell what you salvaged from the sea?"

"Do you understand the value of antiques~"

"Antiques, to put it mildly, represent the process of human beings in all eras, and are the witnesses of the glory of one country after another."

"It's small, just like Sun Hao Niu Pu said, they represent one story after another!"

"You look at antiques and taste the stories that have happened, which is their most essential value."

"How can this value be measured in money?!"

Hearing this, the eyes of everyone in Class 9 lit up, and they regained their interest as if they were resurrected.

I think they were really in love just now!

still looks down on Sun Hao and Niu Pu.

People are the real masters who see the essence through the facts!

That's it, antique!

How can it not be worthless?!

Then they saw their teacher sigh:

"But..."

"If you want to talk about practical value, they may not be very high."

"After all, you also know that this place, it really doesn't have much history..."

"And currency must be regarded as the least valuable of all kinds of antiques."

"Not to mention it's so badly corroded..."

After Ren Yan said that, the eyes of everyone in Class Nine calmed down again, and gradually became expressionless.

Just looked at his teacher so fixedly.

Then why don't you say a p! ’

Seeing this, Ren Yan waved his hand indifferently: "Okay, that's the reason." ”

"Now it's time for you to figure out what to do with the coins."

"Alas, leave one that looks like it, make a commemoration, and hand over the rest, which can be regarded as our contribution to the country."

At this time, Ah Wei seemed to be unusually correct, and he didn't say anything directly.

The other students also nodded:

"Turn it in."

"It's not enough to look at this thing~"

After they finished speaking, Ren Yan nodded:

"Yes, then it's up to you."

"Now, it's time to talk about the stone."

As he spoke, Ren Yansan came to the large treasure chest in two steps:

"First, we have to be sure of one thing."

"The ancients, even pirates, could not be more stupid than us, since we all think that large treasure chests should be filled with valuables."

"How could they not know?"

"So, the value of this giant stone must have been much more valuable than those five boxes of coins at the time."

"Then this thing, after all, is still a stone..."Wang Bo frowned.

"Not necessarily." Ren Yan shook his head: "Historical relics, you can't judge them just from their appearance. ”

"Time will leave a mark on them, whether rust or dust, it can seal its essence."

"At this time, what we have to do is to remove the marks left by time."

After that, Ren Yan clapped his hands:

"Let's get this thing out of this broken box first."

"Inside the box, we don't want to clean it up, let alone soak in the sea."

When the words fell, Sun Hao and Niu Pu, two people who were extremely interested in the story, immediately teamed up with Wang Bo and others to push the box to the ground, so that this 'stone' could be completely rebuilt.

But when the stone came out completely, the expressions of everyone in Class 9 became wonderful again.

I thought that the rust that was originally floating on the stone fell from the metal film tested inside the treasure chest.

But now I look at it, and the rust actually comes from the 'stone' itself.

On the back of the stone, the rust was almost enveloping the stone.

And it's full of potholes.

In addition to this, there are many small 'stones' that have fallen off.

The traces of the surrounding area also look like canine teeth.

"This thing, it's really not a stone..."After the 'stone' came out completely, Sun Hao casually picked up a piece of bits and pieces and looked at it.

But when he looked at it, he felt that something was wrong.

"Eh..., don't you look like gear?"

While speaking, Sun Hao took a small piece and handed it to Wang Bo next to him to take a look.

Wang Bo narrowed his eyes, a little puzzled.

Then he touched it with his hand, and then nodded: "It does mean a bit of gear..."

"But are you sure there were gears in the pirate era?"

"Why not, it's not that difficult to have gears." Li Chengbai is the same as Wang Bo.

"No, I mean there could be metal gears? Shouldn't this thing have come after the Industrial Revolution? ”

"If you want to process a metal component into a gear, is it really possible to do without a machine tool?"

"It's rusty!"

Wang Bo said, and the ninth class suddenly fell into silence.

I even feel a little chill in my back crest.

Oh, yes... In the age of rampant piracy, could metal gears be possible?

If it does appear...

So why are those boxes of coins so poorly made? Can't even make a full circle?

Thinking of this... They suddenly felt colder.

And in the same way, the netizens in the live broadcast room who originally had some balance in their hearts.

also suddenly gasped.

This kind of thing, it's okay if you don't want to, and the more you think about it, your scalp is numb.

An object that should not have appeared in that era, appeared in that era.

Anyone will feel a chill in their backs.

......

On the deck, everyone in Class 9 glanced at each other and tightened their clothes.

They both saw a little fear in each other's eyes.

Ren Yan's brows gradually furrowed.

After pinching his chin and thinking for a moment, he leisurely spat out a word:

"Anachronistic relics..."

"Anachronistic relics?" Hearing this, everyone in Class 9 once again looked at their cheap teacher.

"That's right, a relic of the wrong time." Ren Yan nodded:

"The relic of anachronism is a special term in the archaeological world, referring to the thing in front of us, which seems to be far more advanced than the speculative age."

"Whenever this kind of thing appears in the archaeological world, it always causes a storm."

"Looks like we're not getting nothing this time..."

After that, Ren Yan sighed slightly again, a little lamented by the luck of Class Nine...

No, probably shouldn't even be lucky.

It's luck.

Since he took over the ninth class by himself, these little cubs have always encountered various things inexplicably, and in less than a year, they are about to catch up with the excitement of Ren Yan's previous life.

When I was still a social animal, I didn't have so much to do.

"That's... So what's going on, Mr. Ren? ”

After hearing their teacher's explanation, everyone in Class 9 seemed a little at a loss for a while.

Theoretically, they have encountered enough things, and they have seen a lot.

But in this new field, they still instinctively feel a little timid.

"Let's see if our guess is correct." Ren Yan stretched his fingers and looked at Ah Wei: "Ah Wei, you go to the warehouse and bring over all the brushes and various cleaning liquids that you may use to clean the deck." ”

"Anyway, we'll have to determine what it is, or when it is."

"It's so rusted now, we're going to have to clean it up first."

"Are you sure... With tools to clean the deck? Ah Wei looked a little embarrassed: "Teacher Ren, although I don't know much about antiques, but I haven't eaten pork, we've seen pigs run~"

"Isn't this supposed to be a bunch of gray-bearded old historians in white coats and magnifying glasses, wiping them down little by little with equipment that can be as fine as a millimeter?"

"You're so simple and rude, are you sure you can?"

When the words fell, Ren Yan squinted his eyes and frowned, gritted his back molars, and asked quite painfully: "Haven't you cleaned up the rusty farm tools?" ”

"Although there may be a difference of hundreds of years between the two."

"But you don't think that metal products will be completely crispy in a few hundred years, let alone that this thing is still soaking in the sea."

"How can you be so delicate as you say, people are not the eldest lady!"

"The ones you see from the Internet are the last fine processing, this kind of metal products that have just been discovered, there are not so many things, if it is too fine, it may not be cleaned~"

After that, Ren Yan waved his hand with a stomachache: "Okay, okay, don't look ahead, let you take it, and then you will learn to deal with it with me simply." ”

"Oh~~~"

Hearing this, Ah Wei agreed with his mouth open, and ran towards the warehouse with a few people.

After a while, he returned again with a large bag and a small bag.

Judging from what Ah Wei brought back, the other party implemented his requirements very well, that is, in terms of understanding, there may be such a deviation.

Looking at the iron pin in the cleaning tool, the corners of Ren Yan's mouth spasmed irrepressibly again:

"It's not... Tell you to take the brush or something, what are you doing with the happy ball? ”

Ah Wei replied very seriously: "This thing is extremely efficient in cleaning stubborn stains, I think you can use it!" ”

Listening to the other party's painstaking efforts, Ren Yan hung down his arm weakly, and the words of the admonition were also deeply stuck in his throat.

"Okay, okay, come here, let's open a small stove today and teach you to simply clean up the potential historical relics!"

Ignoring Ah Wei, Ren Yan raised his head and glanced around, and called all the students in Class 9 over.

Because the current 'suspected' stone is too large, there is no need for a special position, and all students can look at it.

After seeing everyone standing, Ren Yan took out a brush from the tool pile, and after sticking it in a bottle of white vinegar a few times, he poured all the white vinegar on the subject.

I glanced at my watch and waited patiently.

While waiting, he explained to the students of Class 9:

"In the treatment of historical relics, in principle, it is not allowed to use any chemical agents, because we are not very sure of the composition of cultural relics, and if one accidentally causes damage to cultural relics, the gains outweigh the losses."

"Therefore, generally in the rust removal of cultural relics, the most used thing is vinegar, vinegar is weak, and it can also play a role in rust removal for a long time, which can be regarded as the safest way to remove rust at present."

"And this method is called the vinegar bubble method in the cleaning of cultural relics."

"In addition to this, there are mechanical, boiling water immersion, dry brushing and heating methods."

"However, there are several other methods that have too many limitations compared to vinegar foaming and need to be used in specific places."

"For example, for smaller impurities, mechanical methods are often used, and it takes great patience and perseverance to carefully deduct excess impurities by holding a needle artificially."

"Boiling water soaking is mostly used to deal with rust, eighty or ninety degrees of water, soaked for about five minutes, a large amount of rust will fall off, and other rust stains will also loosen."

"At this time, it is often used with the dry brush method, and when the rust is not heavy and can be easily cleaned up, you can use a soft brush to brush off impurities, which is also the method you often see on TV."

"As for the last heating method, it's not much the same as soaking in boiling water, but it's mostly used to deal with slight rust or artifacts that can't be soaked in water."

"Our current rust is too heavy and obviously unusable."

"So the best thing to do is vinegar soaking."

"The time is at least ten minutes or more, and some artifacts will even be soaked for 24 hours, but we don't have enough time, so I won't demonstrate so much."

"Remove the rust on the surface and look at the general outline, it will take about ten minutes."

Ren Yan said, and the students of Class 9 nodded in understanding.

There are also many people who habitually take out their mobile phones to make sticky notes.

Ten minutes later, Ren Yan took the brush and carefully began to brush the outermost layer of rust:

"This step, even if it is a dry brushing method, but there is still a difference, because I now know that the rust is too thick, so I don't have to pay too much attention to my movements, as long as I control the force."

"The real dry brushing method is to control the range of the brush between 0.5-0.7 cm from the cultural relics, too close, easy to damage the structure of the cultural relics."

"It's too far away, and it may not be cleaned."

"So this step, what you want is to have a steady hand."

After carefully cleaning for more than ten minutes, it was obvious that a lot of rust had been removed on the surface of the cleaning object, and there were various rust spots on the deck.

Thanks to the long immersion in the sea, these rusts are not very stubborn.

However, when these superficial rusts fell off, Ren Yan's brows furrowed again.

Because within these rust stains, there is a turquoise green.

With the essence of its metal, a thought reluctantly burrowed into Ren Yan's mind.

And there is obviously more than one person who has the same idea as Ren Yan.

After seeing these turquoise, Wang Yu asked:

"This thing is made of copper?"

Ren Yan nodded: "And it may be more than that." ”

"The layer of stone we saw earlier may not be a stone, but a shell made of a layer of other substance."

"Look at this..."

As he spoke, Ren Yan nodded to the other side of the cleaning object: "After a simple cleanup, these stones have begun to detach, and there is also a layer of patina exposed inside. ”

"So this layer looks like a stone, most likely the dust has been accumulated, or the surface layer was deliberately painted by the ancients with some materials..."

"So this thing is a complete piece of metal?" Sun Hao blinked.

"No, it's strictly bronze." Wang Yu shook his head.

"Is there a difference?" Sun Hao was stunned.

"Of course, if it is really a bronze artifact, then our previous speculation about the relics of the wrong era may be wrong."

"After all, bronze has been used by humans since BC, and the first time gears appeared was in the 13th and 14th centuries."

"So, in the days when piracy was rampant, it was quite normal for artifacts with bronze gears to have them."

"Not necessarily." Hearing this, Ren Yan shook his head: "The gear of the thirteenth and fourteenth centuries must be at least half a meter in size, but the one in front of us looks like a dozen centimeters." ”

"There's still a big gap."

"And we don't know what's in there until we get a rough idea."

Ren Yan frowned and looked at the things in front of him, and suddenly had the illusion that Class Nine had caught a big treasure in his heart.

"Go, Ah Wei, boil hot water!"

"We're going to have to clean it up and see what the hell this is."

After a brief thought, Ren Yan looked at the squad leader.

Ah Wei didn't have any ink, so he immediately took Li Cheng to the kitchen to boil hot water.

Ten minutes later, the body of the cleaner became wet, and the water vapor of the birds floated from it.

This time, not only Ren Yan, but even some of the more careful students in Class 9 also picked up the brush and joined the cleaning army.

With his teacher's demonstration, even if everyone in Class 9 is still a little weak-hearted, the progress is a lot faster after all.

As it darkens, they finally clear the entire outline of the object.

But instead of getting better, everyone's faces became more solemn.

In front of them was a rectangular bronze box, covered in turquoise patina.

The shell, as Ren Yan guessed, had a layer of lime shell as protection, but at this time, the lime shell was close to falling apart.

Bronze bodies are exposed everywhere.

At the same time, on top of this shell, there are still some remaining patterns, most of which are round, and many places are completely hollowed out.

And inside this hollow, there are dense stacks of gears.

Although they were not well cleaned, the appearance of the canine teeth betrayed them deeply.

The side of the bronze body also confirms this very well.

But everywhere it can be cleaned, it has revealed what the gears should be.

Even if there are a few small pieces falling off, even after the baptism of time, these sealed gears still bite each other without the slightest deviation.

Install the latest version. 】

The workmanship seems simple, but it gives everyone in Class 9 an unprecedented mechanical rugged beauty.

They may seem rudimentary, but they are uniform.

It seems to be incomplete, but it has passed the test of time and appears in front of them relatively completely.

At this moment, even if there is no need for Ren Yan to say it, everyone in Class 9, including netizens, has already confirmed one thing.

This thing must be a relic of the legendary anachronism.

This kind of seemingly rough but exquisite workmanship, even if it is a modern process, is not easy to make.

Not to mention, it was still in the era of piracy...
