"Mengzi, you have a good look at the boat, I'll go over there and have a look. "Since you can't figure it out, let's go and see, this is Xiao Peng's opinion.

Yang Meng was taken aback when he heard this: "Brother, are you okay? That ship is at least 10 nautical miles away from us, and we can't see it if we don't see it?" How do you get there?" One nautical mile is about 1.8 kilometers, which means that the 'Arctic Penguin' is at least 18 kilometers away from Xiao Peng. There are no lifeboats or anything like that on the 'Guo Chuan', isn't this going to swim over?

Xiao Peng smiled: "Actually, it's not that far, it's only 4 nautical miles away from us, more than six kilometers away, and it will arrive soon." The horizon is not as far away as we think, and we can see a maximum of five kilometers at our height. ”

Yang Meng looked disdainful: "How can the horizon be so close? Besides, how did you figure it out, this must be your nonsense. ”

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

Yang Meng nodded: "You can say it." 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 from the inside, let's assume that the earth is a standard sphere, and you are standing on the sea, then the farthest distance you can see is the tangent between the position of your eye and the surface area, according to the knowledge learned in geometry, we can know that the tangent and the center of the earth are exactly perpendicular to the tangent, then the center of the earth, the tangent and your eyes form a right triangle, the farthest distance from your eyes to what you can see is one of the right angled sides, your eyes are 1.7 meters high from the ground, and the radius of the earth is 6,300 kilometers, that is, 6.3 million meters, according to the Pythagorean theoremThe distance that the human eye 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 will say, you can see up to five kilometers, and it will never exceed this number. ”

With a click, Yang Meng's pipe fell to the deck, and Yang Meng listened to Xiao Peng's words, and opened his mouth wide and couldn't speak. Looking at Yang Meng's expression, Xiao Peng was also very satisfied, and his desperate reading some time ago finally had an effect.

Yang Meng shook his head, came back to his senses, and directly diverted the topic, the scumbag and the scholar will never have a common language: "Then you also have to swim over, don't you? It's too tiring to go so far!"

Xiao Peng smiled and snapped his fingers: "Who said I was going to swim over?" As soon as the words fell, a black back suddenly appeared in the sea, and a triangular dorsal fin was exposed to the water, Yang Meng looked at it and said urgently: ", you are a bug!"

That's right, Xiao Peng just enlightened a Ju's weasel shark in the sea! Let it be his own driver, babble, Meidi is very.

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

"The weasel shark, well, we all call it the tiger shark, but it's a different thing from the real tiger shark. Xiao Peng explained.

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

Xiao Peng said: " We Chinese people, it seems that the name is particularly fond of tiger characters, at least three kinds of sharks in the sea are called tiger sharks, one is a regular tiger shark, more common, except for the Mediterranean Sea and the Atlantic Ocean, it can be seen almost everywhere, but the tiger shark character is mild compared to other sharks, don't look at the length of the long, in fact, it mainly feeds on invertebrates and shellfish; And the other kind of 'tiger shark' is this Ju's weasel shark. Compared to those two tiger sharks, this is really a dangerous guy, extremely aggressive. Nocturnal sharks. In fact, it belongs to the true shark family, but because it is as fierce as a tiger, it is called the tiger shark. ”

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

Xiao Peng smiled: "I'm not afraid of the great white shark, I'm afraid of this little thing?" you watch the boat, don't worry about me, I will definitely come back." ”

Yang Meng saw that Xiao Peng said this, and nodded: "Pay attention to safety." The weasel shark is the largest shark in the true shark family, it grows to five meters long at every turn, and seven-meter weasel sharks are not rare, this is the little thing in your mouth?

Xiao Peng took a sheet from the house, spread it on the back of the weasel shark, then climbed onto the back of the weasel shark and rushed towards the mooring place of the 'Arctic Great Penguin' at high speed.

The reason why I put a sheet on it is because the skin of sharks is too rough, and large sharks such as weasel sharks have scales like iron files, and when they are touched by shark skin, their flesh and blood will be blurred.

That's because the shark's whole body is covered with shield scales, and even the shark teeth are actually its shield scales, and because of this, the shark's teeth can quickly grow back after they fall out, and from another angle, the shark is covered with shark teeth.

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

The speed of the weasel shark is not covered, and soon Xiao Peng came to the place where the 'Arctic Great Penguin' was moored, and the people on board were debugging the machine in various ways to prepare for tomorrow's salvage.

Xiao Peng ignored them, went directly to the place where the shipwreck was shipwrecked, and searched for the shipwreck one by one.

But this search result 。。。。。。 It's really disappointing for Xiao Peng!

There was nothing good on the shipwreck, except for bones, rusty weapons, and broken porcelain in the galley. Xiao Peng slipped around so many boats, and found some ingots and copper coins and the like, the number was not much, Xiao Peng was too lazy to salvage, and then thought about it, he couldn't cheap crooked nuts, so he salvaged them.

"How can you be so poor. Xiao Peng couldn't figure it out: "Is this a group of poor pirates getting together to make a fire?"

It's no wonder that Xiao Peng complained so much, the dozen or so sunken ships here were obviously sunk by people, and many of the corpses on the ships had obvious injuries, looking at the cracks in the bones, it was more like a knife cut or something like a wound.

Xiao Peng's disappointed don't want it, this time, the only thing that is certain is that these ships are indeed the ships of Zheng Shi's Red Flag Gang. The inscription on the bow testifies to all this.

Xiao Peng still didn't give up, and looked around these sunken ships again, but the result was still empty. In addition to those rusty swords and cannons, it can only be said that some old oil lamps can still be considered objects. Now Xiao Peng really feels disgusting, opening the door to disgusting------ disgusting to the home. It's too disappointing that the end of the hopeful end is like this.

But that can't be helped, Xiao Peng was also about to give up, ready to go back to find Mengzi, just wanted to hitchhike again, but found that the weasel shark couldn't be found. I turned my head and looked, hey, he's chasing a green turtle for its life.

Everyone thinks that the natural enemies of sea turtles are humans, but in fact, as everyone knows, there are people in the sea who like to hold turtles for tooth sacrifices, and this weasel shark is recognized as the natural enemy of sea turtles.

Xiao Peng was a little distressed to see the green sea turtle, the green sea turtle is also an endangered species, it is the only species of sea turtle that feeds more seaweed, because its staple food is seagrass and large seaweed in the sea, so the fat accumulates a lot of green pigment, showing a light green, hence the name. Its feeding area is mostly freshwater areas rich in seaweed, and there is a lot of seaweed on the submarine reef not far from the wreck area, which is probably why the green turtle is here. Unfortunately, this green turtle was unlucky and ran into a weasel shark.

Xiao Peng just wanted to stop the weasel shark, but he didn't expect the green turtle to rush towards the reef, which scared Xiao Peng, what are you doing? Is this a victim of the weasel shark who wants to commit suicide by hitting the reef?

At the moment when the green turtle was about to hit the reef, it suddenly turned around and the green turtle was gone. Not to mention that Xiao Peng was stunned, even the weasel shark was flustered, why was the delicacy gone?

The shipwreck disappointed Xiao Peng, but the green turtle made Xiao Peng feel interested, did he see a hallucination? The bottom of the sea is haunted? Thinking of this, Xiao Peng swam to the reef and wanted to find out.

There was a large amount of algae growing in the reef area, which made it more difficult for Xiao Peng to advance, and Xiao Peng carefully pushed aside the algae to the place where the green sea turtle disappeared.

Xiao Peng looked around and frowned, except for seaweed and sea anemones, there is nothing else here, where did the green turtle go? Xiao Peng looked back at the weasel shark, and the weasel shark was more confused than it. It's still rummaging through the seaweed looking for the green turtle, but it doesn't seem to be able to count on it.

Xiao Peng was confused, today's shipwreck trip is really hell, more than a dozen shipwrecks found some ingots copper coins, a green turtle also disappeared out of thin air in front of him, Xiao Peng now only feels that there are 10,000 grass and mud horses floating in his heart, he must not have looked at the yellow calendar when he went out today, why is nothing going well?

Xiao Peng was depressed, and just wanted to turn around and leave, but he made a major discovery: behind the big anemone, there was a big hole more than one meter high! The big anemone and seaweed covered the hole tightly, so Xiao Peng didn't even find it just now.

Xiao Peng's curiosity also came, it seems that the big turtle ran into the hole? Xiao Peng thought about it, and directly put his mind clone into the hole, which was black and black, who knows if there are any ruthless guys in it? Not to mention anything else, a moray eel popped out of such a hole, it would be enough for Xiao Peng to drink two pots. If there is a big octopus, it will be even more disgusting. If it's a blue-ringed octopus or an Ekiterin sea snake, then Xiao Peng's life may have to contribute, right?

Of course, it is unlikely that Xiao Peng will be killed, but after all, safety first is not it?

However, it seems that Xiao Peng is obviously thinking too much, this cave is actually a natural karst cave made of volcanic rock, and the space inside is not small, except for the poor green turtle, there are no other creatures in it.

Xiao Peng relieved himself and bowed down into the cave, ready to find out.
