Godly Fisherman

Due to the obstruction of electromagnetic waves by water, there must be a long and thick cable between the early deep-sea exploration ship and the working mother ship for communication. The Star-Stripe Nation's "Elvin" was the first working mode of this kind, and later With the advancement of science and technology, a new communication method is adopted, namely underwater acoustic communication.

Underwater acoustic communication is to convert text, images and other information into electrical signals through an electrical transmitter, and then the encoder digitizes the information to achieve the purpose of communication. Now due to the communication rate limitation, only photos and voices can be transmitted at present. When the technology of the transducer and algorithm is broken in the future, you can play with the mother ship like in sci-fi movies. Up.

Nowadays, science and technology are advancing with each passing day, and maybe that step will be done soon, but according to the current technology level, it can only send a black and white photo, send a voice, send a text, etc.

Xiao Peng looked at the monitor: "Mengzi, your fourth row of searchlights is not turned on. Is it a malfunction? Over."

After a while, Mengzi's voice came: "I forgot to open it just now. Okay, the collision avoidance sonar called the police. Let me see what's going on. We will contact you later! Over!"

Emilia exclaimed: "This is amazing too, right?"

Xiao Peng said: "It's okay. At present, only a few countries in the world have this technology. This technology has always been owned by those military developed countries, and the old rules —— block China technology, we have this technology now. Technology has been developed step by step through scientific and technological research. Now it can reach a communication distance of 10,000 meters, and it is conquering a communication distance of 50,000 meters."

"Then what are we doing now?" Emilia asked.

Xiao Peng shrugged: "What else can you do? Wait, after you come back, you can watch the video taken by the camera of the "Warrior of the Seas".

What has he never seen in the seabed? He has no interest long ago, so let Yang Meng play this time!

Emilia hurriedly said: "How long will it take to wait!"

Xiao Peng shook his head: "With Yang Meng's character, he must be addicted to it. If it is two thousand three hundred meters, 70 minutes will go down and 70 minutes will go up. Let's see how long he plays! Anyway, it can't exceed 12 hours. ."

"Why?" Emilia asked.

Xiao Peng smiled and said, "Why else? The continuous working time of the Four Seas Warrior is twelve hours."

Emilia complained to Xiao Peng and said, "I blame you, I won't let me go down and take a look at such a fun thing!"

Xiao Peng smiled and said, "Okay, baby, it's too dangerous to go down. Besides, you can't see anything when you go down. It's darkness below 200 meters. What you can see is just a few meters from the light. At a depth of one thousand meters, it is really dark and cold there, and the water depth remains at zero to three degrees all year round, and it will not freeze because the seawater there is also dense and salty, and the pressure is still high. If you can reach that depth, It's equivalent to having thirteen statues of Liberty with pedestals pressed on you. Think about how dangerous it is. They might already regret why they want to go down now."

Emilia complained: "But I want to go down! I want to see the strange fish in the sea."

Xiao Peng shrugged: "If you take a submarine, you may not be able to see it. This'Warrior of the Four Seas' is gravity diving. It is about the same as the diving speed when you throw a rock into the water, and 90% of the fish in the world It is living in the'dusk zone', also called the mid-level floating zone. That is, the position between two hundred meters and one thousand meters below the sea level. And there are not many fish that can be seen under one thousand meters."

"Then what are we doing now?" Emilia asked.

Xiao Peng thought for a while, and showed a wicked smile: "I take advantage of the fact that no one is bothering now, otherwise we will go back to the room and happily do something that only the two of us can do?"

Emilia blushed after hearing this: "What do you think! Don't do it! You just thought about this early in the morning, you are too bad!"

Xiao Peng was taken aback for a moment: "What do you think? I mean let's go back and play chess! You female rascal."

Emilia pinched Xiao Peng a few times angrily: "You obviously meant that! You obviously meant that!"

Xiao Peng laughed and said, "Then you don't want to go? Okay! Let's go fishing then."

Emilia considered for a while and blushed and said, "Then let's go back to the room."

After Xiao Peng heard this, he didn't go back in a hurry, but rummaged through the drawer there.

Emilia asked curiously: "My dear, what are you looking for?"

Xiao Peng replied: "I'm looking for chess!"

"Hate!" Emilia made Xiao Peng smile angrily.

Xiao Peng laughed, holding the intercom and said: "Wang Hu, come and stare at the boat, I'll take a rest!"

Wang Hu and the others were fishing outside. Hearing Xiao Peng's words, Wang Hu handed the fishing rod to Xiaoqiu. No one could stare here. The state of various instruments like the "Warrior of the Four Seas" can be seen here.

Back then, the "Jiaolong" lost contact on the seabed for an hour and aroused the attention of the Chinese people. The reason for the loss of connection event is that the diver accidentally switched the communication channel to a special communication mode, in which only communication can be performed, and other data channels are automatically closed. In the end, the mother ship on the sea could not receive normal data information, which shocked people.

In fact, the people on the mother ship observe the state of the submarine through various data.

When Xiao Peng happily embraced Emilia and returned to the room, he was in a different state at the bottom of the sea.

"Ah, you didn't vomit?" Yang Meng looked at McAfee with a big bag. That is a vomit bag for McAfee. When the submarine was first launched, it shook extremely badly. Vomiting was most likely to occur within a depth of 30 meters, but it was fine when it was 30 meters below.

McAfee was pouting his **** and lying on the observation window to look out. Hearing Yang Meng's words coldly snorted: "Don't think I don't know what you mean, you just want a chance to stun me! I won't give You have a chance. I said, did we dive too fast? I can't see anything!"

Yang Meng gave him a white look and handed him a towel: "Don't be a curious baby there! Work quickly! Wipe all the condensation water! It's raining in the cabin."

McAfee took the towel: "Then what are you doing?"

Yang Meng coldly snorted: "You come to steer the boat to keep your balance? Then I will wipe it!"

After hearing this, McAfee took up a towel angrily to wipe the condensation on the observation window.

The seven observation windows on the “Warrior of the Four Seas” are all made of special glass in the shape of a truncated cone (the cone is sawn off the upper tip). The diameter of the one close to the inside of the ship is only 250 mm, but in the submarine The outside diameter is 600 mm. It's like a big speaker. The special glass and special shape allow it to withstand high pressure on the seabed without breaking, and it is also convenient for people inside the ship to observe the outside of the ship.

However, due to the low sea temperature and high temperature in the cabin, a large amount of condensate is generated in the cabin, including the observation window and overhead cabin door, which must be wiped off.

McAfee spit out while rubbing, "I thought I could play with the fish, but it turned out well and became a cleaner."

Yang Meng held the head of the joystick and said without turning back: "If we don’t use gravity to dive, and we should have the power to dive, it will be twelve hours after we reach the bottom of the sea. Do you think it’s possible? Besides, you’re not just It’s a cleaner, you’re still our photographer, record all this, maybe this is our last words!"

McAfee was speechless: "You are nonsense enough to talk crow's mouth against me, but you are even more crow's mouth than me!"

But he said so, and he really took out the camera to record what happened between the two in the cabin. Originally, the dive process was very boring, but the two people quarreled and didn't feel bored. After the collision avoidance radar sounded the alarm, the two men stopped the discussion. Yang Meng carefully drove the Four Seas Warrior. After releasing the ballast iron, the hull shook slightly. Yang Meng handed the hydro-acoustic communication radio to Mike. Fei: "Give you a chance to perform and tell the above that we have arrived."

After hearing this, McAfee did not directly communicate with the "Warrior of the Four Seas". Instead, he slumped on the detection window and observed the outside with the light: "It looks so desolate. It's really different from what I imagined."

"Nonsense! This is the deep sea." Yang Meng looked at the screen: "This place is like a small beach by the river, with a piece of yellow sand and a few water plants.

"Where are we now?" McAfee asked.

Yang Meng told him: "Just tell the above, we are here in the middle of the ocean and they will understand."

"Ocean Ridge? What is that?" McAfee asked puzzledly.

Yang Meng explained: "The mountain range on the sea floor is also the largest mountain range on the earth. It traverses all the oceans on the earth. The total length is more than 60,000 kilometers. We are on this mid-ocean ridge now. Have you seen the sonar picture? The first two kilometers is the central rift valley. The Somali basin we are going to is actually a central rift valley. The widest such rift valley is more than ten kilometers, and the deepest can be three kilometers deep. This Somali basin is considered a small rift. "

"There are also mountains under the sea?" McAfee asked.

"Nonsense! This mid-ocean ridge mountain range circled the earth, and not only on the bottom of the sea, some places simply left the surface of the sea and became islands!" Yang Meng explained, "Icelandic volcanoes, right? There are islands such as the Azores, Ascension, and Galapagos, all of which are mid-ocean ridges that protrude from the sea. Shit, what shall I tell you? There is a high-pressure air bottle behind me, press it quickly .Tell the above, according to the sonar that we are on the steep **** of the mid-ocean ridge, I plan to find it nearby——you can work fast! Let you come not as a statue! Wipe, the top ten There is a target in six meters. Didn't we fall into a hole?"

"Huh?" McAfee's face changed a lot after hearing this.
