Due to the obstruction of water to electromagnetic waves, there must be a long and thick cable between the early deep-sea exploration ship and the working mother ship. This was the first working mode of the "Irwin" of StarCraft. With the progress of science and technology, a new communication mode was adopted, namely underwater acoustic communication.

Underwater acoustic communication is to convert text, image and other information into electrical signals through an electric transmitter, and then the information is digitized by encoder to achieve the purpose of communication. At present, due to the limitation of communication speed, only photos and voice can be transmitted at present. When the technology of transducer and algorithm is broken through in the future, we can play with the mother ship like in science fiction movies.

With the rapid development of science and technology, we may be able to achieve that step in a short time. However, according to the current level of science and technology, we can only transmit a black-and-white photo, a voice and a text.

Xiao Peng looked at the monitor: "Mengzi, your fourth row searchlight is not on, is there something wrong? It's over. "

After a long time, Mengzi's voice came: "I forgot to open it just now. OK, the collision avoidance sonar has called the police. I'll see what's going on. We'll contact you later! Over

"Isn't it amazing?" she sighed

Xiao Peng said: "it's OK. At present, only a few countries in the world own this technology. This technology has always been owned by those military developed countries, and the old rule is to block China's technology. The technology that we have now is developed step by step through scientific and technological research. Now, it has reached a communication distance of 10000 meters and is tackling 50000 meters of communication distance. "

"What are we doing now?" Amelia asked.

Xiao Peng shrugged: "what else can I do? Wait. When you come back, you can watch the video from the camera of the four seas warrior. "

What's going on at the bottom of the ocean that he hasn't seen? He has no interest for a long time. Let's give it to Yang Meng this time!

"How long will it take?" Amelia said in a hurry

Xiao Peng shook his head: "with Yang Meng's character, he must be addicted to it. Besides, if he is 2300 meters long, he will go down in 70 minutes and come up in 70 minutes. He is watching how long he plays! It's not more than 12 hours anyway. "

"Why?" Amelia asked.

Xiao Peng said with a smile, "why else? The continuous working time of the four seas warrior is 12 hours. "

Amelia complained to Xiao Peng and said, "it's all your fault. I won't go down and have a look at such a funny thing!"

Xiao Peng said with a smile: "OK, baby, it's too dangerous to go down. Besides, you can't see anything when you go down. It's dark under 200 meters. What you can see is the range of several meters illuminated by the light. Moreover, at a depth of 3000 meters, it is really dark and cold. The water depth is kept at zero to three degrees all the year round, and it will not freeze because the sea water there is also dense, salty and under great pressure. If you can get to that depth, it is equivalent to 13 statues of liberty with bases on your body. Think for yourself how dangerous that is. They may have regretted why they went down now

Amelia complained, "but I just 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 that the" Four Seas warrior "is gravity diving, which is similar to the diving speed when you throw a stone into the water. 90% of the fish in the world live in the" twilight zone ", also known as the mid-level planktonic zone. That's 200 meters to one kilometer below sea level. And when you go down a kilometer, you don't see many fish. "

"What are we doing now?" Amelia asked.

Xiao Peng thought for a moment and showed a bad smile: "while no one bothers us now, or we will go back to the room and do something that only we can do."

Amelia blushed after hearing this: "what do you think! Don't do it! Don't do it! It's too bad of you to think about this in the early morning

Xiao Peng was stunned: "what do you think? I mean, let's go back to chess! You rascal. "

Emilia angrily pinched Xiao Peng a few times: "you clearly mean that! That's exactly what you mean

Xiao Peng said with a smile, "don't you want to go? ok Let's go fishing

Amelia thought for a moment, blushing, "let's go back to the room."

But Xiao Peng didn't go back to the drawer.

Amelia asked curiously, "honey, what are you looking for?"

Xiao Peng replied, "I'm looking for chess."

"Disgusting!" Emilia made Xiao Peng laugh.

Xiao Peng laughed and said with his walkie talkie, "Wang Hu, come and stare at the boat. I'll go and have a rest."

Wang Hu and Wang Hu are fishing outside. When they hear Xiao Peng's words, Wang Hu gives the fishing rod to Xiaoqiu. No one is watching here. The status of various instruments like the four seas warrior can be seen here.

At that time, the Jiaolong lost contact for an hour at the bottom of the sea, which attracted the attention of the Chinese people. The reason for the loss of communication is that divers accidentally switch the communication channel to a special communication mode, in which only communication can be achieved and other data channels are automatically closed. Finally, the mother ship on the sea could not receive the normal data and information, which scared people.In fact, people on the mother ship observe the state of submarines through various data.

When Xiao Peng hugs Amelia back to his room happily, he is in a different state at the bottom of the sea.

"Why, you didn't vomit?" Yang Meng holds a big bag and looks at McAfee. It's a vomit bag for McAfee. When the submarine was just launched, it was extremely shaking. When it was just 30 meters deep, it was easy to vomit, but it was OK when it was under 30 meters.

Michael Fei was lying on the observation window with his buttocks pursed. After listening to Yang Meng's words, he snorted: "don't think I don't know what you mean. You just want to find a chance to stun me! I'm not going to give you a chance. I said, did we dive too fast? I can't see anything! "

Yang mengbai glanced at him and handed him a towel: "don't be a curious baby there! Work fast! Wipe all the condensation! It's raining in the cabin. "

McAfee took the towel. "What are you doing

Yang Meng snorted coldly: "do you want to keep your balance? Then I'll wipe it

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

The seven observation windows on the "Four Seas warrior" are all made of special glass. The diameter of the cone near the inside of the ship is only 250 mm, but the diameter outside the submarine is 600 mm. It's like a big trumpet. The special glass and special shape can make it withstand high pressure on the sea floor, and it can also facilitate people inside the ship to observe the outside of the ship.

However, due to the low temperature of the sea water and the high temperature in the cabin, a large amount of condensate water has been produced in the cabin, including the observation window and the hatch on the top of the cabin, which must be wiped off.

McAfee, while rubbing and tucking aside, "I thought I could play with fish, and make complaints about it, and became a dustman."

"If we don't use gravity diving, we should have the power to dive. When we get to the bottom of the sea, it will be 12 hours later. Do you think it's possible? Besides, you are not only a cleaner, you are also our photographer. Record all this, maybe this is our last words

McPhee was speechless: "you are such a bullshit. You dislike me for talking crow mouth, but you are more crow mouth than me!"

However, he said that he did take out the camera to record what happened in the cabin. Originally, the diving process was very boring, but the two people didn't feel bored when they were fighting each other. After the collision avoidance radar gave out an alarm, the two stopped discussing. Yang Meng drove the "Four Seas warrior" carefully. After releasing the ballast iron, the hull shook slightly. Yang handed the underwater acoustic communication intercom to McAfee: "give you a chance to show your performance. Tell me that we have arrived."

Instead of communicating directly with the four seas warrior, McAfee leaned over the detection window and observed the outside with the light: "it looks so desolate. It's quite different from what I thought. "

"Nonsense! This is the deep sea. " Yang Meng looked at the screen: "here is like a small beach by the river, a piece of yellow sand, erect a few water grass, this is done?"

"Where are we now?" McAfee asked.

Yang Meng told him, "tell the upper authorities that we are the mid ocean ridge, and they will understand."

"Mid ocean ridge? What is that? " McAfee asked, puzzled.

Yang Meng explained: "the mountains under the sea are also the largest mountains on the earth, crossing all the oceans on earth. The total length is more than 60000 kilometers. We're on the mid ocean ridge right now, see the sonar? Two kilometers ahead, that is the central rift valley. The Somali basin we are going to is actually a central rift valley. The widest Rift Valley is more than ten kilometers, and the deepest one can be three kilometers deep. This Somali basin is called a small rift valley. "

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

"Nonsense! This mid ocean ridge mountain range has made a circle around the earth. It is not only at the bottom of the sea, but in some places it simply leaves the sea and becomes an island Yang Meng explained: "Icelandic volcano, you know? There are also Azores, ascension, Galapagos and other islands, all of which are mid ocean ridges protruding from the sea. Why should I tell you this? I have a high-pressure air bottle behind me. Pressurize quickly. Tell the above, according to the sonar, we are on the steep slope of the mid ocean ridge. I plan to find it nearby. You should work quickly! You're not supposed to be a statue! Wipe, there is a target 16 meters above the front. We didn't fall into a hole, did we? "

"Ah?" McPhee's face changed a lot.
