Pirate Spring Fruit

"Hey, what a thick book."

There is much more knowledge about navigation than Bellamy imagined.

The next day, the Portcas Chamber of Commerce directly brought a cart of books over.

He sorted it out for a long time and found out the part that the captain had to learn, and then his head started to hurt.

Driving a sailboat is not just about sailing the boat.

At the very least, you have to know which way the wind is blowing, right?After all, sailboats run on the power of the wind.

You have to know where the channel is, right?

Where is it easy to hit the rocks, where is it easy to be stranded, how many meters of water is the current draft of the ship, and which port is a shallow water port and cannot be docked.

This is the most basic skill of a captain.

"So how did Luffy get the ship up and running?"

Bellamy looked at the thick tome in his hand, and the corners of his mouth kept twitching.

It will take at least a week to finish reading this book.

Memorizing them all would take only a few months.

"No, I can't suffer alone."

The captain is studying hard, how can his dearest men stay out of it?

So Bellamy held a study session and forced his men to start reading.

"Read me at least ten pages a day, assholes!"

This requirement is really very low, but I can’t help but neither Ross nor Drake likes to read.

The two ladies said it didn't matter. The reaction of these two guys after getting the book was exactly the same as his.

His brows were furrowed, his eyes were wandering, and then he was in a daze, in a daze, in a daze, and continued to be in a daze.

Anyway, I just can’t read it.

But you can’t do it if you don’t learn. How can you sail a boat if you don’t learn?How can you go to sea without learning?

Could it be like Luffy, sitting in a small barrel and going to sea?

Don't be ridiculous, if there is a big wave, they will feed all the fish.

So the difficult days began.

------

A month later.

At noon, in the front yard of the martial arts hall.

Mia stood in front of a fish basket, fiddling with something curiously.

Today Bellamy gave everyone a day off to rest.

Everyone has had a very hard time this month, after all, his requirements are so strict.

Several ladies went to the town for a long time shopping and bought back a lot of messy things.

This fish basket was brought back from the port area by Mia, and she didn't know what was in it that could make her so obsessed with it.

Lunch time was coming soon, but from the look of her, she didn't seem to have any intention of cooking.

"Hey, Mia, I'm hungry." Bellamy hurriedly urged when he saw this.

"I know, I know." Such a perfunctory tone.

What was inside made her so curious that she didn't even want to burn the food.

Bellamy walked up to her and squatted down in front of the fish basket.

"This is?"

Isn't this Pipi shrimp?

This thing is really rare, at least in Beihai, this is the first time he has seen it.

"Hey, with this color and these hammer-shaped fists, isn't this a bird-tailed mantis shrimp?"

"Captain, do you know this beautiful shrimp?"

"Tell me about their habits and whether they can be fed." It seemed that Mia liked this kind of creature very much.

Also, the sparrow-tailed mantis shrimp is colorful and very beautiful, especially when it is in the water, it looks like a moving rainbow.

But despite this little thing’s unique appearance, he is actually one of the few bullies in the sea who can walk sideways.

Bellamy remembered that in the aquarium in his previous life, Pipi shrimps were basically not kept.

Because Pipi Shrimp will kill and eat all creatures that are not more than dozens of times its size.

Yes, it is so cruel.

The combat effectiveness of this little thing is unparalleled for its same size.

"Of course it can be fed, but you have to build a thicker water tank to avoid being broken by it."

A thicker tank?Broken?

Mia picked up a sparrow-tailed mantis shrimp and measured it with her fingers. This little thing was probably only a dozen centimeters in size. How could it break the water tank?

Seeing her actions, Bellamy couldn't help but raise his eyebrows, "Don't extend your fingers."

But it seemed that he reminded her a little too late. When the shrimp girl moved her fist, an afterimage flashed by, and Mia immediately screamed in pain.

"My finger!"

Bellamy quickly grabbed her hand and looked at it. Fortunately, it was only swollen and the finger bones were not broken.

"Don't underestimate this guy, its fist can easily create supercavitation bubbles in the water."

The so-called supercavitation, to put it simply, means that the instantaneous acceleration is too fast, the violent friction produces terrifying temperatures, and the water is evaporated before it can react.

Then a bubble appeared in place.

The forcibly ejected air bubble will collapse in the next moment, emitting a strong flash and releasing huge energy.

How huge is this energy? As Bellamy knows, the moment the cavitation collapses, its internal temperature can reach several thousand degrees.

This level of acceleration is impossible even if Bellamy turns on first gear and then turns on super ejection mode.

So even if Mia's finger bones were broken just now, he wouldn't be too surprised.

Because the bird-tailed mantis shrimp is so awesome, this guy was the fastest punching creature in the world in his previous life.

"Wait a minute." When he thought of being the fastest in the world, an idea suddenly flashed in his mind.

Bird Tail Mantis Shrimp. .Supercavitation. . .

Hyperboloid!

"Hyperboloid structure!"

These five big words popped into his mind.

Why the bird-tail mantis shrimp is so awesome is precisely because of its hyperboloid structure.

What is a hyperboloid structure? To describe it simply, it is a saddle.

The saddle is the most typical hyperboloid structure.

To give a few more examples, recurve bows, Sydney Opera House.

They are all very typical hyperboloid structures.

The hyperboloid structure contains huge elasticity. Its principle is to use the least material and contact area to create the most stable structure.

While receiving force, the hyperboloid contracts, stores energy, releases it, and explodes instantly.

This is a classic structure that matches Spring Man almost perfectly.

If he could transform the muscles and bones in his arms into a hyperboloid structure, could he have the power to easily create supercavitation?

Thinking of the excitement, Bellamy hugged Mia and took a bite, "You are really my lucky star."

"I'm going to heaven!"

Bellamy suddenly seemed to go crazy, grabbed a Pipi shrimp and ran away.

Mia wiped the saliva on her face in disgust, picked up the small basket on the ground and shook it casually, "This little thing doesn't have wings? How can it go to heaven?"

"Isn't the captain going crazy reading a book?"
