Let you teach, you play games with the worst class?

"Why, now that people are old, they don't pay attention to reputation? I remember you agreed to this a few hours ago."

"It's different!" Cao Guorui yelled again, and Ding Guoxiang silently put away the receiver: "I promised you before because you told me that their Class [-] found a sunken ship, and it was in the Bering Strait. I just let go of something worthy of attention."

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

"What could it be?"

Seeing that his old friend was very impatient, Ding Guoxiang asked along the way.

But the answer he got made him feel bad.

"A mechanical computer!"

......

"A mechanical computer?"

"What is it?"

Nine on deck.

After seeing the pile of mechanical gears on the object to be cleaned up, a term buried in Ren Yan's heart welled up in her heart, and she blurted it out with a good heart.

This made everyone in Class Nine, including the drone, aim at them.

Ren Yan spread her hands helplessly:

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

"It also has another name, called the Difference Engine."

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

"In other words, this thing, strictly speaking, may be a computer composed of machinery?!"

Listening to his teacher's explanation, Wang Yu, as the university bully with the most extensive knowledge in Class Nine, uttered in shock.

Because he usually reads a lot of extracurricular books, he has heard of the term difference machine.

And have been fascinated by it for a while.

The reason is that this thing is too wonderful.

With just the rotation of some gears, complex formulas can be calculated, and there is a sense of inconceivability everywhere.

But at the same time, Wang Yu also had some doubts:

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

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

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

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

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

"Under these conditions, can you confirm that the Difference Engine as depicted in the punk world does not have a real prototype?"

After roughly explaining the origin of the difference engine and answering Wang Yu's question, Ren Yan glanced at all the students in Class Nine.

At this moment, they are still in a kind of horror.

As if the nerve endings had been struck by a bolt of lightning, there was even some emptiness in his eyes.

Seeing this, Ren Yan clapped her hands:

"And, the most crucial point..."

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

"Is what exists now necessarily correct?"

"This is the fundamental reason for the existence of archeology, we know so little about the past world..."

After all, Ren Yan coughed angrily twice, and everyone in Class Ninth returned to their senses. Afterwards, he made a final conclusion:

"Of course, everything I've said so far is also my own guesswork."

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

After saying that, Ren Yan let out a long breath, feeling that this should completely arouse the interest of everyone in Class Nine to explore.

However, in fact, it was somewhat beyond Ren Yan's expectations.

After a burst of shock, everyone in class nine didn't pay attention to the last two words Ren Yan said, but put all their thoughts on the difference machine.

Especially student Awei, who was the most caring.

The two gray eyeballs immediately burst into an astonishing brilliance.

He looked back and forth between 'Difference Engine' and Ren Yan, then rubbed his hands together:

"So, this thing is very valuable?!"

"How can you describe it as valuable? It's quite valuable!" Li Cheng responded immediately: "Didn't you listen to Teacher Ren just now?"

"This thing is ancient black technology!"

"If it is really confirmed, it is light to say that it is an astronomical figure!"

"Doesn't that mean that our Class Nine is out?!

"Ah Wei's eyes burst out with a stronger light again.

The body began to tremble a little due to excitement.

"Yeah, post it, post it!"

On the side, everyone in Class Nine continued to drink.

Only Ren Yan's face darkened, and he almost fell down: "What are you thinking?!"

"Even if this thing is really a difference engine, don't even try to sell it!"

"Is there anyone who can really afford to buy it?"

"Do you think that if you take out this thing and sell it, can its ownership really belong to you?"

"Do you want me to repeat the truth that everyone is innocent and pregnant with crime?!"

After the words fell, Ren Yan glared at everyone in class nine.

He felt that these children were really a little ignorant.

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

They were just joking about what they said just now.

Even if Teacher Ren didn't say anything, they knew very well that if this kind of thing was really confirmed.

It must be the country's action.

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

more?That's crossing the line!

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

Ren Yan sighed inwardly, and waved at Awei: "Awei, follow me to the captain's room."

"Others, what should they do!"

After saying that, 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 might really fall into the eyes of money and be unable to extricate himself.

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

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

After casting a sympathetic look, the other students gathered around the 'difference engine' again, wanting to find out.

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

At the same time, in the live broadcast room.

A group of netizens also started searching immediately.

Not long after, the full set of information of the difference engine appeared on the barrage.

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

Also a little relieved.

I understand why those pirates put this thing in the big treasure chest back then.

A computer that has crossed the ages must be considered a treasure, right? !

Immediately, a new question arose involuntarily.

Where did these pirates get this thing from? Why is such a valuable item easily snatched by pirates?

Moreover, this difference engine, what exactly does it calculate?

They can check very clearly just now.

In theory, the difference engine can only calculate one type of formula fixedly, and if you want to calculate another formula, you need another set of gears.

The division of labor is very clear~

......

In the captain's room of Class Nine.

After not thinking about the difference engine for a while, Ren Yan casually moved a chair for student Ah Wei to sit in.

Then, patiently, he asked rather strangely:

"I said, how do you think that everything has something to do with money?"

"I've never seen you such a money fanatic before."

"You even want to sell the difference machine, don't you know what the consequences might be if this thing is sold?"

"Its best home will always be a museum."

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

"But you don't know how much Class Ninth spends now."

"The daily food expenses alone are conservatively estimated to be around [-]."

"Even if we are at sea, part of it can be self-sufficient, but the necessary supplies must be prepared. After arriving in other countries, we must have the necessary expenses."

"Not to mention, we still have a boatload of pets. You don't know how edible those pets are, and how expensive their feed is!"

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

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

"Sometimes I even feel that what I have is not a pet, but a bunch of ancestors, and their food is more expensive than us!"

Seeing the angry Ah Wei, the corners of Ren Yan's mouth twitched involuntarily.

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

His cat didn't feed himself any cat food, he ate whatever he ate.

Aren't you still alive and kicking now?

"Is there such a possibility... that your understanding of pets is a bit too much."

"In the past, whether it was a pirate or a navy, they would keep some cats on their ships."

"Do you know why?"

"Why?" Ah Wei blinked in confusion.

"Because there will be rats on the ship, and cats are kept to prevent rats."

"It's all right now, you feed the cats so well, it's better to raise a litter of mice to save money."
