"Lao Ding!"

"I can't say anything this time!"

"That thing salvaged by Class Nine is of great significance, and it must not be allowed to let those laymen destroy the heavens anymore!"

"If it's really a relic of an anachronism, as they say, do you know how much of a shock it will have to the entire archaeological community?!"

Long Guo, inside the office of the General Administration of Education.

Ding Guoxiang took the landline earpiece far away with a disgusted face.

But even so, an old and energetic voice could still be clearly heard coming from the earpiece.

On the other end of the phone, it's no one else.

It is the director of the General Administration of Archaeology that he has just contacted before, and he is also his old classmate, Cao Guorui.

This old man has a fiery temper since he was young, and he originally thought that the other party had reined in a lot after he got old.

But who knew that this product was just a superficial effort.

Now when it comes to antiques, the energy of the past is back...

After the other party's roaring slowed down a little, Ding Guoxiang put the phone receiver close to his ear:

"Didn't you say it before? This matter is entrusted to the General Administration of Education, and your General Administration of Archaeology is not involved. ”

"Why, now that people are getting older, they don't pay attention to credibility? I think you said yes a few hours ago. ”

"It's different!" Cao Guorui roared out again, and Ding Guoxiang silently took the earpiece: "I promised you before, because you told me that their ninth class found a sunken ship, or in the Bering Strait, there may be nothing worth paying attention to, so I relented." ”

"But now it's different, do you know what that pile of gears might be?!"

"What could it be?"

Seeing that his old friend was very anxious, Ding Guoxiang asked casually.

But the answer he got made him feel bad.

"Mechanical computers!"

......

"Mechanical computers?"

"What is it?"

On the deck of the ninth class.

After seeing the pile of mechanical gears on the cleaning subject, a term buried in Ren Yan's heart came to his heart, and he blurted out that he couldn't die.

This made everyone in Class 9, including the drone, all aimed at it.

Ren Yan spread his hands helplessly:

"A mechanical computer, as the name suggests, is a computer made of machinery."

"It also has another name, it's called the Difference Machine."

"Corresponding to our current electronic computer, it is a machine that will appear in the mechanical age."

"In other words, this thing, strictly speaking, could be a computer made up of machinery?!"

Listening to his teacher's explanation, as the most knowledgeable university bully in Class 9, Wang Yu was shocked.

Because of the relatively large amount of extracurricular books read, he has heard the term differential machine.

And for a while, I was fascinated by it.

The reason for this is because this thing is so amazing.

With the rotation of a few gears alone, complex calculations can be calculated, and there is an incredible sense of wonder everywhere.

But in the same way, Wang Yu also has some doubts:

"Isn't this thing a fantasy of the past?"

"I read the book that this thing is just a theoretical possibility, and there is no possibility of reproduction in reality?"

Hearing this, Ren Yan nodded: "Theoretically, this thing is indeed a fantasy. ”

"And mostly from the world of punk, a world made entirely of wasteland and machinery."

"In that fantasy world, this kind of mechanical computer is an indispensable computing tool, and it is also a vital material for major forces."

"But you also know..."

"Fantasy or literary works always come from life, even if they are fabricated out of thin air, there will always be some archetypes."

"Under these conditions, can you confirm that the difference machine depicted in the punk world doesn't have a real prototype?"

After roughly explaining the origin of the differential machine and answering Wang Yu's question, Ren Yan's gaze swept over all the students of Class 9.

At the moment, they were still in a state of horror.

It was as if a nerve endings had been struck by a bolt of lightning, and there was even some hollowness in his eyes.

Seeing this, Ren Yan clapped his hands:

"And, most crucially..."

"How much do we really know about the true history of the past?"

"Is what exists now necessarily correct?"

"This is the fundamental reason why archaeology exists, we know very little about the world of the past..."

After that, Ren Yan coughed angrily twice, so that everyone in Class Nine came back to their senses, and then he made a final summary:

"Of course, everything I'm talking about so far is my own speculation."

"If you want to really know what this thing is, you're going to need to keep looking for more information."

When the words fell, Ren Yan let out a long breath, feeling that this should be able to completely arouse the interest of everyone in Class Nine to explore.

However, in fact, it was somewhat unexpected by Ren Yan.

After a thick shock, everyone in Class Nine didn't care about the last two sentences that Ren Yan said, but put all their minds on the difference machine.

Especially Ah Wei, who is the most attentive.

The two eyeballs, which were originally gray, immediately burst out with amazing color.

He looked back and forth at the 'Difference Machine' and Ren Yan, and then rubbed his hands:

"So, this thing is worth a lot of money?!"

"How can it be described as valuable? That's pretty valuable! Li Cheng immediately responded: "Didn't you listen to Teacher Ren just now?" ”

"This thing is ancient black technology!"

"If it is really confirmed, it is said that it is astronomical, then it is light!"

"Doesn't that mean that we are in class nine, and we have sent it?!

Ah Wei's eyes burst out with a more intense light again.

Their bodies began to tremble with excitement.

"Uh-huh, it's gone, it's gone!"

On the side, everyone in Class 9 kept drinking.

Only Ren Yan's face turned dark, and he almost fell: "What do you want?!" ”

"It's just that this thing is really a difference machine, you don't want to sell it!"

"Let's not say if anyone can really afford it."

"Do you think if you take out this thing and sell it, the ownership of it will really belong to you?"

"I want to say it again if I am innocent and guilty?!"

When the words fell, Ren Yan glared angrily at everyone in Class 9.

He felt that these children were really a little unimportant.

Seeing this, everyone in Class Nine smiled awkwardly and didn't care much.

They were just talking and joking.

Even if Teacher Ren doesn't say it, they know very well that if this kind of thing is really solid.

It must be the state that will do it.

Now in their hands, it's just a hand, at most, to explore the mystery of this thing, that's all.

More? That's crossing the line!

However, Ah Wei had a bitter face, obviously a little unconvinced.

Ren Yan sighed secretly in his heart, and waved his hand at Ah Wei: "Ah Wei, you come to the captain's room with me." ”

"Others, what should they do!"

After the words fell, Ren Yan turned around and walked towards the captain's room, he felt that he had to teach Ah Wei a good lesson.

Otherwise, this kid may really fall into the eyes of money and can't extricate himself.

If it really develops to this point, it will be a serious dereliction of duty on his part as a teacher.

Hearing this, Ah Wei's expression collapsed, and he followed Ren Yan into the captain's room.

The other students, after casting a sympathetic look, gathered around the 'Difference Machine' again, wanting to explore a thing or two.

Now, the attraction of this thing to them has increased exponentially.

At the same time, inside the live broadcast room.

A group of netizens also immediately launched a search.

After a while, the full set of information about the difference machine appeared on the barrage.

It wasn't until this moment that they realized what an outrageous thing Class Nine had caught.

At the same time, I was a little relieved.

I kind of understand why those pirates put this thing in the big treasure chest.

A computer that spans the times, how can it be regarded as a treasure, right?!

Immediately, a new question arose.

Where did these pirates get this thing from, and why could such a valuable item be easily looted by pirates?

And, this difference machine, what exactly does it calculate?

They just found it very clear.

Differential machines, theoretically speaking, can only calculate one type of equation fixedly, and if you want to calculate another equation, you have to use another set of gear sets.

The division of labor is very clear~

......

In the captain's room of the ninth class.

After not thinking about the difference machine for the time being, Ren Yan casually moved a chair for Ah Wei to sit down.

Then he patiently asked, rather strangely:

"I said, how do you think that anything can have anything to do with money now?"

"I've never seen you kid so rich before."

"I even want to sell the difference machine, I don't know what the consequences of this thing being sold?"

"Its best place to return is always a museum."

Hearing this, Ah Wei shook his head quite bitterly: "I don't want to, Teacher Ren." ”

"But you don't know how much Class Nine is spending now."

"The daily food cost alone is conservatively estimated to be about 3,000."

"Even if we are at sea, some of them can be self-sufficient, but we have to prepare the necessary supplies, and when we reach other countries, we have to spend the necessary expenses."

"Not to mention, we still have a boatload of pets, you don't know how much that group of pets can eat, and how expensive their feed is!"

"Take cat food as an example, a bag of nutritious standard cat food costs more than 100 yuan, but one bag is enough for a cat for a week."

"On our ship, there are more than 20 cats alone, and other pets eat more!"

"Sometimes I even feel like I'm not having pets, but a bunch of ancestors, and they eat more than we do!"

Looking at Ah Wei who was huffing, the corners of Ren Yan's mouth couldn't help twitching.

Turning his head to look at the short-legged cat he raised, the corners of his mouth twitched even more.

He didn't feed his cat any cat food, he ate whatever he ate.

Aren't you still alive and kicking around?

"Is there such a possibility..., it's that your understanding of pets is a little too much."

"In the past, both pirates and navies would have cats on their ships."

"Do you know why?"

"Why?" Ah Wei blinked in confusion.

"Because it's going to make a lot of noise on the boat, and cats are kept to prevent mice."

"Well, now that you've fed the cats so well, you might as well save money by raising a litter of mice."

"But pets, aren't they all raised like this?" Ah Wei opened his mouth with some pain.

Ren Yan scoffed: "." ”

"If all the pets were raised like this, wouldn't all the pets that used to be guarded have to starve to death?"

"The feeding tutorials that are now being talked about on the Internet are all soft and wide played by pet feed manufacturers in order to make profits."

"Even if some pets are indeed squeamish and precious."

"But do you think they're really fragile enough to kick their legs right away after a bite of leftovers?!"

"Everyone is here to take in energy, and as long as the energy is sufficient, there is no reason why you can't feed it."

"You guys, let's watch less of those breeding tutorials on the Internet in the future."

After the words fell, Ren Yan glanced at Ah Wei with sympathy.

Ah Wei's whole expression immediately squeezed together: "I'll go, it's too dirty..."

"Can it be like this, are they shameless?"

"You talk to the capital about face?" Ren Yan glanced at Ah Wei strangely.

Ah Wei's face turned black in an instant, and then he took out a notebook and opened it to check:

"In addition to pets, we also have a lot of other expenses, let's say this trip to Suluo, we spent a total of 283,253 yuan."

"That's it, I haven't calculated the loss of the ninth class number."

"And, most crucially, we have basically no income right now."

"Since going to sea, the Jiuban business platform has completely lost its partners, and Li Cheng's private dishes have become a thing of the past."

"Only the farm still has a small income, but in order to make the farm better, we have to put a fixed amount of money into it every month."

"With such a back and forth, we are now equivalent to only being able to get in and out."

"We've only just started our voyage, and we're still halfway to our full route."

"You say I don't have to rush Teacher Ren."

"If you don't know how expensive firewood, rice, oil and salt are not at home~"

For a while, Ah Wei's expression was completely bitter.

Ren Yan also somewhat understands the reason why Ah Wei now regards money as his life.

It's not because this kid is greedy, but because this kid has too much sense of responsibility.

I feel that as the chief housekeeper of Class 9, I have to be responsible for all the logistics of Class 9.

But in fact, the logistics of the current situation of Class 9, even if Xiao He comes, it is estimated that there is no trick.

However, Ren Yan was still a little stunned.

During a trip to Suro, they did buy a lot of things, but would there really be 280,000 so much?

In his calculations, it should be in the early 200,000s.

After all, there are still some things that can be returned.

For example, on the day I went to talk by myself, I didn't actually spend too much, not even the cost of alcohol, which is equivalent to prostituting a bar for nothing.

For example, those tools that are purchased also have discounts and returns.

The most important thing is that they can buy the treasury bonds of the Dragon Kingdom!

How could it be so poor?

With this curiosity, Ren Yan took Ah Wei's notebook.

It's full of accounts.

The terms are clear and clear at a glance.

Even in order not to be messy, Ah Wei also made a catalog.

The degree of care can be seen in general.

But looking at it, Ren Yan felt that something was wrong.

He casually found a project for the expenditure of Class 9 and looked at Ah Wei:

"What about the follow-up of your expenditure?"

"Follow-up? What's the follow-up? Ah Wei looked at his teacher in a daze, a little puzzled.

"It's the follow-up destination of this money in exchange for things, now I only see how this money is gone, but I don't see its more specific use."

"In the case of this expenditure, it is true that tools are purchased, but are all of these tools really being used? Will it be redundant? ”

"But I can't see any of this."

"If the tool is less than 100% utilized, does that mean you can still sell some to increase your income?"

Hearing this, Ah Wei's whole person slowly opened his mouth wide, a little incredulous.

He had never thought about that.

Now there are a lot of things that eat ash on the ninth class, it seems that there are indeed a lot?

And Ren Yan did not continue to dwell on this article, but turned to the national debt.

Very good, the national debt is really the same as he thought, only expenditures, no follow-up specifics.

The omission was so great that he was staggered:

"Look at this again, we bought the Treasury bonds, but what about after that?"

"And then again?"

"Won't the national debt bring us income?"

"Where does all this income go?"

"But the teacher... It's true that there is no income from the treasury now, and this is what we have been holding for a long time. Ah Wei retorted weakly.

"No, don't think that holding it for a long time means you don't have to keep it." Ren Yan waved his hand: "There is a specific direction of capital flow in the treasury bonds. ”

"Can't you deduce your own profit from the direction of these flows?"

"Although these are long-term and cannot be obtained immediately, they will always be delivered to you at some point."

"Are you going to wait until then to count them?"

"That large sum of money will immediately destroy your existing accounts, and make everything you have recorded in vain, without any meaning."

"Maybe, I'll have to suffer a lot for this."

"The flow of funds is not a matter of one in and one out, as a big steward, you have to consider the movement of funds at every moment."

"Only then can you make sure that every account is clear and clear."

"And this method, known in the accounting industry as double-entry bookkeeping, is currently the most important and accurate bookkeeping method for all companies."

"If you use this method, do you think what you have recorded is still accurate?!"

After that, Ren Yan shook Ah Wei's account book with a smile.

Ah Wei looked up at the ceiling, thinking frantically about what Ren Yan had mentioned just now.

After a while, his eyes lit up, and he instantly pulled out of the emo state.

If it is really according to what their own teacher said, the potential class fee that exists in their ninth class is much more than the one on the surface.

And these, the follow-up can be guaranteed to be exchanged for funds!

In this way, wouldn't the dilemma they thought about in Class Nine be solved?

Perhaps, the situation that I felt that I couldn't make ends meet before was also my own worry?!

Thinking of this, Ah Wei immediately laughed:

"Teacher Ren, why didn't you say such a good way earlier!"

"I've lost a lot of hair these days."

"You didn't ask~" Ren Yan shrugged.

Seeing this, Ah Wei rolled his eyes and ran out of Ren Yan's captain's room in a hurry.

Looking at his hurried back, Ren Yan instructed in the back: "Remember, this thing is called double-entry accounting." ”

"There should be something written in those books you bought!"

"Got it! Thank you, Mr. Ren! ”

After a while, Ah Wei's voice came from around the corner.

Looking at the captain's room with the door open, Ren Yan smiled and shook his head.

Ah Wei's potential problems have been solved by himself.

Coupled with that differential machine, it was a really fruitful day.

However, Ren Yan is happy here.

Wang Bo rushed in in a hurry:

"Teacher Ren, it's not good!

”

"We've got a guy out of the sea!"
