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

Stop fussing now.

At the same time, because of this accident, everyone in class nine also discovered the flaws in the current number of class nine.

One, there is no complete ship detection system, and the whole ship has to go to check if something goes wrong.

It is easy to miss and waste time.

It took them nearly 6 minutes to find the watertight cabin that was hit just now.

If there is any hidden injury in Class Nine in the future, why won't you be able to sleep during the investigation? !

As for the second point, it is the wooden outer hull of Class Nine.

Although this thing is convenient and hard enough, it is still prone to the risk of cracking due to the texture of the material itself.

Just like this time, although there is no great risk, this kind of worry is inevitable.

So for these two visible problems.

Everyone in Class Nine clapped their hands and decided to improve immediately after arriving at Suluo Port.

For the first question, add a scanning system and you're done.

The second question is even simpler, they plan to directly wrap a layer of iron on the outside of the hull.

Although it may seem nondescript, but fortunately it is safe!

As for the class fee for these two tasks?

There is no other way, these are all imminent matters, and if you want to save them, you can't save them.

Seeing classmate Ah Wei who looked hopeless and wanted to go to the deck immediately to find Li Cheng's blood-splattered five steps, Ren Yan finally couldn't bear to stop him.

"It's just five steps of blood splashing, it's inhumane."

"Next time, you should directly deduct Li Cheng's pocket money..."

Hearing this, Ah Wei stagnated, and after thinking for a while, he nodded reluctantly:

"It's okay..."

"How do you say that this kid is also the chef of all of us, it's really broken, and it's not suitable."

Ren Yan was taken aback for a moment, always feeling that student Awei's starting point seems to be very strange.

At the same time, he began to sympathize with Li Cheng for a little while.

This kid's current class status is probably on par with pots and pans?

Shaking his head, after throwing these miscellaneous things out of his mind.

Ren Yan silently sighed:

"Okay, let's go back to the deck first, so we haven't processed a bunch of tuna yet."

"Also, I have to explain something to you."

After finishing speaking, Ren Yan turned and walked towards the deck, and Ah Wei and the others immediately followed.

On the deck, the students of Class Nine gathered together again.

Next to it, there is a large pile of tuna they caught before.

Everyone stared at Ren Yan with burning eyes, expecting their teacher to give them an answer.

Now, they've probably confirmed that the tuna is a good thing, but they still don't understand.

What a good fish, why can't you think about it if you can't think about it?

And there is such a great power, no matter how you think about it, it feels incredible.

Ren Yan didn't bother to talk nonsense, after letting everyone find a place to sit down, he grabbed a kitchen knife, picked up a tuna and started to process it.

Explain as you go:

"I know your confusion."

"Thought a creature shouldn't be like this."

"But as I said before, tuna is not very courageous, and it is easy to be frightened."

"Once it is frightened, it will immediately turn on the charge mode."

"The big ball of bait Li Cheng used to not only startle the tuna with a big movement, but also make the tuna riot because of the fragrance it emits."

"Accidents may happen if either of these two occurs, let alone the combination of the two."

"But even so, it doesn't have to bump into the south wall, it's just a matter of turning a corner." Wang Bo asked with a frown.

Ren Yan looked up at him and waved her hand:

"The average speed of this thing in the sea can reach 80 kilometers per hour, and the instantaneous explosive force can reach nearly 200 kilometers per hour."

"It will be very close to our No. [-] shift."

"Under this kind of haste, under normal circumstances, you can't react at all."

"If you are surprised again, let alone."

"Of course, under normal circumstances, tuna can turn, and it's a [-]-degree right-angle turn."

"The secret of this is hidden in its fins."

"The fins of this thing have a natural hydraulic device, which is why it has such a high speed."

While speaking, Ren Yan had already scratched off the fin of the tuna, rinsed it with water casually, and threw it to everyone in class nine.

The fins of this fish are not big, even in terms of the size of the tuna itself, it can be called a mini.

But it is such a small thing that gives the tuna an incredible swimming ability.

Everyone in Class Nine formed a circle, stacked up and down, wanting to see the secrets in the fins, but it seemed that they didn't find anything different.

I just feel that the muscles connecting with the body seem to be quite developed.

And in between there is a compartment of a lighter color, but there is nothing unusual about it.

"That's the compartment." Ren Yan said at the right time.

"In that compartment, there is this biomass hydraulic system, but it cannot be seen with the naked eye. You have to find something to zoom in to see it."

"Of course, a certain degree is fine."

"You can understand all of these, and use them as the capital to go out and brag in the future."

While speaking, Ren Yan smiled self-deprecatingly.

To be reasonable, in her previous life, Ren Yan did a lot of things like collecting gossip and bragging.

It's just that now it has become a piece of knowledge in his teaching.

I have to say, this feeling is really amazing.

Hearing this, the eyes of the students in Class Nine lit up, as if they had discovered the secret of their teacher's erudition!

But Ren Yan was unmoved. After laughing, he began to explain the following question:

"As for the power of this thing that you were wondering about before."

"Actually, that's a better explanation."

"Because tuna grows itself into a fleshy cannonball when it grows up, with tight muscles all over its body, and in order to keep the body alive."

"They're full of hemoglobin all over their bodies."

"This is also the reason why tuna cannot be kept for a long time."

"Too perishable."

"And this kind of body structure, coupled with their rapidity, and the shape of a cannonball."

"Think about it, how would it feel to be hit by this thing?"

"The Sea Cannonball isn't called for nothing."

"The tuna that hit our boat before should not be big, otherwise it would be impossible to have such a small scar."

Speaking of this, Ren Yan has also broken down the tuna into two sides.

It was completely placed in front of everyone in class nine.

In their eyes, these two huge tuna meat exuded a sense of strength.

Although it looked miserable because of the bloodstains.

But they can still feel the power contained in those muscles.

Seeing this, everyone in Class Nine nodded suddenly, and had a new understanding of tuna.

"Then why did this thing die as soon as it landed?"

After a while, Wang Yu frowned.

He hasn't figured it out yet.

"Because this thing can't breathe on its own."

Ren Yan explained:

"Their way of breathing is very unique. They breathe by allowing the water to continuously wash over their gills."

"They don't have the ability to inhale on their own."

"That's why they have to be quick."

"They can only survive if there is a constant flow of water into their gills."

"And because of this, they even swim when they sleep, which can be said to be a model of continuous progress from birth."

Speaking of this, Ren Yan suddenly laughed:

"Oh, right."

"Speaking of a model."

"Actually tuna evolved this way mainly to avoid being caught."

"It will die as soon as it stops, and the meat will spoil quickly, which will make it taste particularly unpalatable."

"And under normal circumstances, there is no marine life that can chase it, so it can be said to be extraordinarily safe."

"But this group of unlucky guys met such a freak as humans."

"The tight meat quality and high concentration of hemoglobin make it the top red meat in the seafood market."

"So the price of this thing is very high now."

"This may be another example of self-defeating..."

Hearing this, everyone in Class Nine was a little bit dumbfounded.

Simply put, the creature tuna is constantly adding points on the way to survive.

Forcibly added a flesh and blood cannonball to himself.

Escaped the hunting of all marine life.

But in the end, it somehow became the way humans like it.

In front of other sea creatures, humans directly ntr.

There is such a miserable smell everywhere.

As a result, Class Jiu suddenly felt a little distressed when he looked at the pile of tuna beside him.

These days, such a real creature is hard to find...

But looking at it, they felt that something was wrong:

"No, Teacher Ren."

"If the tuna is really like what you said, it is impossible for us to catch it."

"The speed is so fast and the strength is so great, so why not drag us into the sea?"

"This thing, you can't catch it without a few good guys fishing together?"

"Yeah." Ren Yan washed her palms and nodded: "Theoretically, that's true."
