Open an aircraft carrier to fight against Japan

After Gu Zetong said this, everyone stopped talking. Gu Zetong reached out and turned on the walkie-talkie carried on his shoulder, switched to the frequency of talking with Yu Feng, and said: "Call the sea, I am a stream, please answer if you hear it." .”

Yu Feng said: "Please tell me about the stream, I am the sea!"

Gu Zetong said: "We didn't hear anyone's voice in the Japanese submarine, and one of our soldiers fell to the ground when he went down into the submarine. I don't know what's going on?"

Yu Feng asked: "Did someone hide in the dark and shoot?"

Gu Zetong said: "Probably not, we didn't hear the gunfire."

Yu Feng thought for a while and said, "Okay, I understand, that soldier must have been injured by the poisonous gas."

Gu Zetong asked, "Toxic gas? What do you mean?"

Yu Feng said: "When the submarine is working, it will produce a lot of exhaust gas. These exhaust gases are somewhat poisonous. For example, the arsine gas produced by the battery in the submarine is a toxic gas. When the submarine is working, these gases will be destroyed. The ventilation system was replaced, but our torpedo hit the Japanese submarine, and this hit probably destroyed the submarine's ventilation and exhaust system, so the gas remained in the submarine."

"And once the ventilation and exhaust system is broken, no fresh air will enter the submarine. The carbon dioxide content in the submarine will increase and the oxygen content will decrease. If our torpedo causes a fire, the oxygen inside the submarine will be further reduced, so It’s not surprising that people faint in it.”

Gu Zetong asked: "Isn't there a chemical in the submarine that can turn carbon dioxide into oxygen?"

Yu Feng said: "I know that those medicines are peroxides, which can react with carbon dioxide to produce oxygen, but those things are sealed and stored, and they will only be opened when they are needed. If the Japanese army does not have time to open them, or there is a mechanical failure, they cannot open them." , then they would have no oxygen to use."

Gu Zetong said: "So that's the case, what should we do now?"

Yu Feng said: "Go down with a soldier with good physical strength first, and bring up the fainted soldier below, and I will send out a small boat to send you some oxygen cylinders and breathing masks. You will not be afraid of harmful gases if you take them down. .”

Gu Zetong said: "Okay, we understand." Gu Zetong then called a soldier and said: "Your diving time is the longest, which means that you can work for a longer time without oxygen. That fighter comes up, remember, be fast and don't breathe in."

The soldier nodded, took a deep breath, jumped down from the gangway on the side of the hatch, and picked up the fallen soldier when he went down. Not too long later, another assault boat came and brought 20 There were multiple sets of breathing equipment, and two officers who were familiar with submarines were accompanying him. In order to make the operation smoother, Yu Feng sent these two officers.

Gu Zetong led the men to put the oxygen mask on their face, carried the oxygen cylinder on their backs, and then went down into the submarine. Below the command platform is the command room, where there are various operating consoles. Seeing several people in military uniforms, Gu Ze waved at the same time, several soldiers rushed forward, put their hands on their necks, and then reported: "Company commander, five are dead, and one is alive!"

Gu Zetong pointed to the top with his hand and said, "Send the living one to the top."

When the two soldiers heard this, they carried the unconscious guy outside. At this time, Gu Zetong said: "Divide into two groups, one group will search forward, and the second group will follow me and search backward. Each group is equipped with An officer who understands submarines." After Gu Zetong finished speaking, he walked to the back cabin, and everyone acted separately.

Passing through the command room, you come to a cabin full of beds. There are four floors of these beds from top to bottom, and the space on each floor is extremely small. People lying in it can barely turn over. The officer said to Gu Zetong : "This is the living cabin. There are 40 beds in total. It seems that the Japanese submarine has more than [-] people."

Everyone then walked forward, and there was another living cabin behind, but this living cabin has a separate bed and is very spacious. The officer pointed to the cabinet in the cabin and said to the soldiers: "This is the captain's cabin. Open the cabinet and take away everything with writing on it."

After the officer finished speaking, he took out a large sack from his backpack and threw it to the soldiers. One soldier took it, opened the cabinet, and stuffed all the papers and books inside into the sack. The soldier was collecting information, and the others Then walking forward, everyone saw two guys lying on the ground by the side of the passage. After looking over, they found that they were already dead. One of them stretched his hand desperately upwards, as if trying to grab something on it. .

Gu Zetong couldn't help looking up, and asked, "What is this devil trying to grab with his hand outstretched?"

The officer looked up, pointed at what looked like a wrench, and said, "He's probably going to grab that!"

Gu Zetong asked, "What does that thing do?"

The officer shook his head and said, "It's too high, I can't see it, who will build me a ladder?" A soldier squatted on the ground after hearing this, and patted himself on the shoulder with his hand. Then he stood up, quickly jumped down and said: "I understand, that thing is the switch of the oxygen regeneration medicine board, and when it is flipped, the carbon dioxide can contact the peroxide inside to generate oxygen."

Gu Zetong couldn't help laughing and said: "The little devil is really funny, why is this switch set at such a high place? Isn't this just to make yourself awkward?" After Gu Zetong finished speaking, everyone laughed, except The officer didn't laugh, but said sternly: "That's not the case. It may be installed at such a high place to prevent accidental touches. The cost of the oxygen regeneration medicine board is relatively high and cannot be wasted easily. They may have made mistakes before." Accident!"

Everyone suddenly realized that the officer pointed to the cabin in front and said: "Since they want to open the oxygen regeneration medicine board, it means that there is a lack of oxygen in the boat. Under normal circumstances, oxygen will not be lacking. The lack of oxygen is enough to cause coma and death. There was a fire in one of the cabins, and the diesel in the diesel engine room at the back is most likely to burn, so everyone should be more careful when entering the diesel engine room."

Everyone quickly entered the cabin below, and saw a few "human bodies" lying here and there in disorder. The reason why they were called human bodies was that these things only resembled people in appearance, and their skin had been burnt black, like a piece of charcoal. The cabin was full of black ash, and it was obvious that there had been a fire. The officer nodded and said, "This must be the diesel engine cabin where the fire broke out. There is nothing to see. Let's go to the back."

Gu Zetong said: "Didn't you say that there are more than 40 people on this ship? But what we see now is only more than 20 people. Where did half of the people go? Did they all gather in the back cabin? "
