Godly Fisherman

"Mengzi, you are optimistic about the boat, I'll go there and take a look." Since you don't understand, then go and take a look.

Yang Meng was shocked when he heard this: "Brother, are you okay? That ship is at least 10 nautical miles away from us. We can't see it without seeing it? How did you get there?" One nautical mile is about 1.8 kilometers. This means that the Arctic Penguin is at least 18 kilometers away from Xiao Peng and the others. There is no lifeboat on the'Guochuan', isn't this going to swim over?

Xiao Peng smiled: "In fact, it is not that far away. It is only 4 nautical miles away from us, which is more than 6 kilometers away. It will soon arrive. The horizon is not as far away as we imagined. At our current height, we can at most. Look at the distance of five kilometers."

Yang Meng looked disdainfully: "Where is the horizon so close? Don't tease me. Besides, how did you figure it out? It must be your nonsense."

Xiao Peng smiled evilly: "Are you sure you want to know?"

Yang Meng nodded: "Just tell me. I don't believe you can come up with a scientific truth."

Xiao Peng coughed dryly, cleared his throat, and said, "According to your height, even if your eyes are 1.7 meters away from the inside, we assume that the earth is a standard sphere. If you stand on the sea, then you can see the most The long distance is the tangent between the position of your eyes and the surface area of ​​the ground. According to the knowledge learned in geometry, we can know that the line between the tangent and the center of the earth is exactly perpendicular to the tangent. Then the center of the earth and the tangent are perpendicular to you Your eyes form a right-angled triangle. The farthest distance from your eyes to the right-angle side you can see is one of the right-angled sides. Your eyes are 1.7 meters above the ground, and the radius of the earth is six thousand three hundred kilometers, which is six hundred. 300,000 meters. According to the Pythagorean theorem, the distance that human eyes can see is 4628 meters. Of course, the earth is not a pure circle, and your eyes are higher than 1.7 meters. So I said, you can see at most five. Kilometers will never exceed this number."

With a click, Yang Meng's pipe fell on the deck. Yang Meng listened to Xiao Peng's words and opened his mouth wide to speak. Seeing Yang Meng's expression, Xiao Peng was also very satisfied, and his desperate reading a while ago finally worked.

Yang Meng shook his head, regained his senses, and changed the topic directly. Xueba and Xueba never have a common language: "Then you want to swim there too? It's too tiring to be so far!"

Xiao Peng smiled and snapped his fingers: "Who said I was going to swim over?" As soon as the voice fell, a black figure suddenly appeared in the sea, and a triangular dorsal fin came out of the water.

Yang Meng took a look and said anxiously: "Fuck, you are a BUG!"

That's right, Xiao Peng had just set off a Jus ferret shark in the sea! Let it be its own driver, eh, Meidi is very.

Yang Meng stretched his head and glanced at the sea: "I'm going, this is a big guy! What kind of shark is this?"

"Ju's ferret shark, well, we all call it a tiger shark, but it and the real tiger shark are two different things." Xiao Peng explained.

"What a mess!" Yang Meng let Xiao Peng's explanation go around.

Xiao Peng said: "We Chinese people seem to like tiger characters in naming. At least three types of sharks in the sea are called tiger sharks. One is a regular tiger shark, which is more common. Except for the Mediterranean and the Atlantic, it can be seen almost everywhere. For other sharks, they are mild. Regardless of their size, they mainly feed on invertebrates and shell animals. There are also sand tiger sharks, which also carry the word "tiger", but they belong to the family of convolute sharks. The sand tiger shark has a fierce appearance, but its personality is often very docile. Unless it is provoked, it is not aggressive. Generally speaking, it is a star in major aquariums. When people see people swimming with sharks, they are often That thing; and the other kind of'tiger shark' is this Ju's ferret shark. Compared with those two tiger sharks, this is really a dangerous guy, extremely aggressive. Nocturnal shark. In fact, it belongs to Real sharks of the order Real sharks, but they are called tiger sharks because they are fierce as tigers.

Yang Meng listened to Xiao Peng's introduction, but he became nervous: "Then you will be fine, will you?"

Xiao Peng smiled: "I'm not afraid of great white sharks. I'm afraid of this little thing? You look at the boat, don't worry about me, I will definitely come back.

Seeing that Xiao Peng had said so, Yang Meng nodded: "Be careful." He said that, but Yang Meng kept spitting out in his heart, small things? The ferret shark is the largest shark in the real shark family. It grows to five meters in length. The seven-meter ferret shark is not a rare thing. Is this the little thing in your mouth?

Xiao Peng took a sheet from the house, spread it on the back of the ferret shark, then climbed onto the back of the ferret shark, and rushed towards the mooring place of the ‘Great Arctic Penguin’ at high speed. Yang Meng's eyes full of little stars-he wants to play too!

The reason why I put a sheet on it is because the shark's skin is too rough. For big sharks like the ferret shark, the scales are like iron files, and the skin of the shark will become bloody.

That’s because the shark’s body is covered with shield scales. Even the shark’s teeth are actually its shield scales. Because of this, the shark’s teeth can grow back quickly after they are lost. From another perspective, the shark’s body is full of teeth. Not an exaggeration. . . . . .

Xiao Peng didn't want to be bloody, so he found a sheet to cover the shark's back.

The speed of the ferret shark is not superficial. Soon Xiao Peng came to the place where the ‘Great Arctic Penguin’ was anchored. The people on the boat were debugging various machines and preparing for the salvage tomorrow.

Xiao Peng ignored them and went straight to the shipwreck under the sea, searching for the shipwreck one by one.

But this search result. . . . . . It really disappointed Xiao Peng!

Apart from the bones, rusty weapons, and broken porcelain in the kitchen, there was nothing good on the shipwreck. Xiao Peng slid around so many boats and found some ingots and coins. The amount was not large. Xiao Peng didn’t bother to salvage it. Later, I thought about it. I couldn’t get the nuts cheaply. Then I took a closer look and found the ones worth salvaging. Let's talk about it when you catch it!

"How can you be so poor?" Xiao Peng couldn't understand: "Is this a group of poor pirates fighting together?"

It's no wonder that Xiao Peng made such complaints. The dozen or so shipwrecks here were obviously sunk by people, and many of the corpses on the ship had obvious damage. The cracks in the bones looked more like cuts like a knife.

Xiao Peng is disappointed and don't want it. When I come down this time, the only certain thing is that these boats are indeed Zheng Shi's Red Flag Gang. The inscription on the bow proves all this.

He still didn't give up, and looked around on these sunken ships again, but the result was still empty. Except for the rusty swords and cannons, some old oil lamps can only be regarded as objects. Now Xiao Peng really felt nausea and his mother opened the door to nausea - the nausea came home. It was so disappointing that the hope was so full.

But there was no way, Xiao Peng also planned to give up, and was about to go back to find Mengzi, but found that the ferret shark could not be found. Turned his head and saw, hey, it was desperately hunting a green turtle.

Everyone thinks that the natural enemy of sea turtles is humans. In fact, they do not know that there are people in the sea who like to hold sea turtles to fight their teeth. This ferret shark is a recognized natural enemy of sea turtles.

Xiao Peng felt painful when he saw green sea turtles. Green sea turtles are also endangered species. They are the only species among sea turtles that eat more seaweeds. Because its staple food is seaweed and large seaweeds in the sea, many green pigments accumulate in the fat, showing lightness. Green, hence the name. Its foraging areas are mostly seaweed-rich freshwater areas, and there are a lot of seaweeds on the submarine reefs not far from the shipwreck area. This should be the reason why this green sea turtle is here. It's a pity that this green turtle was out of luck and ran into a ferret shark.

Xiao Peng just wanted to stop the ferret shark, but he didn't expect the green sea turtle to rush towards the reef. This shocked Xiao Peng. Why? Is this being chased by a ferret shark who wants to hit the reef and commit suicide?

But at the moment when the green sea turtle was about to hit the reef, the green sea turtle disappeared suddenly when he turned around. Now let alone Xiao Peng was stunned, even the ferret shark was shocked, why didn't the deliciousness in his mouth disappear?

The shipwreck disappointed Xiao Peng, but this green turtle made Xiao Peng interested. Did he see an illusion? Haunted under the sea? Thinking of this, Xiao Peng swam to the reef, wanting to find out.

There are a lot of algae growing in the reef area, which made Xiao Peng's advance more difficult. Xiao Peng carefully pushed aside the algae and came to the place where the green sea turtle disappeared.

Xiao Peng looked around and frowned. Except for seaweed and anemone, there was nothing else here. Where did the green turtle go? Xiao Peng looked back at the ferret shark, but the ferret shark was more confused than it. Still looking for green turtles in the seaweed, yes, it seems that it can't count on it.

Xiao Peng was confused. Today’s trip to the shipwreck was really a hell. More than a dozen sunken ships found some silver ingots. A green turtle disappeared out of thin air in front of him. Xiao Peng now only feels 10,000 in his heart. The grass mud horse drifted by, and I must have not read the almanac when I went out today. Why is everything going wrong?

Xiao Peng was depressed. He just wanted to turn around and leave, but he found out: Behind the big anemone, there is a big hole over a meter high! The sea anemone and seaweed covered the hole so tightly that Xiao Peng hadn't noticed it just now.

Xiao Peng's curiosity also came. It seems that the sea turtle ran into the cave? Xiao Peng thought for a while, and put the mind clone directly into the hole. It was so dark inside. Who knows if there is anything ruthless in it? If nothing else, it would be enough if a big eel popped out in such a hole. Xiao Peng drank two pots. Xiao Peng couldn't bear that bite, didn't he?

However, it seemed that Xiao Peng was thinking too much. This turned out to be a natural cave made of volcanic rock. The space inside was not small, except for the poor green turtle, there were no other creatures inside.

Only then did Xiao Peng relax and dive into the cave to find out.
