After Gu Zetong said this, everyone didn't say more, Gu Zetong stretched out his hand and turned on the walkie-talkie on his shoulder, switched to the frequency of talking to Yu Feng, and said: "Call the sea, I am a stream, please answer when you hear it." ”

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

Gu Zetong said: "We didn't hear the voice of people in the Japanese submarine, and one of our fighters fell to the ground when he went down to the submarine. ”

Yu Feng asked, "Is there someone hiding in the shadows and shooting?" ”

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

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: "The submarine will produce a lot of exhaust gases when it is working, and these exhaust gases are somewhat toxic, such as the hydrogen arsenide gas produced when the battery in the submarine is working, which is a toxic gas, and when the submarine is working, these gases will be replaced by the ventilation system, but our torpedo hit the Japanese submarine, and this hit is very likely to blow up the submarine's ventilation and exhaust system, so these gases remain in the submarine." ”

"And as soon as the ventilation and exhaust system is broken, there will be no fresh air entering the submarine, and the carbon dioxide content inside the submarine will increase, and the oxygen content will decrease, and if our torpedo causes a fire, the oxygen inside the submarine will be further reduced, so it is not surprising that people will pass out inside."

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

Yu Feng said: "I know that those agents are peroxides, which can react with carbon dioxide to produce oxygen, but those things are sealed and preserved, and they will only be opened when they need to be used. ”

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

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

Gu Zetong said: "It's good, we understand. Gu Zetong then called a fighter and said: "Your diving time is the longest, which means that you can work longer in an environment without oxygen, you go down and carry that soldier on your back, remember, be fast, don't inhale." ”

The soldier nodded, took a deep breath, jumped down from the gangway on the side of the hatch, and went down to carry the fallen soldier up, the time was not long, another assault boat came over, and sent more than 20 sets of breathing equipment, accompanied by two officers who knew submarines, Yu Feng sent these two officers in order to make the operation smoother.

Gu Zetong led the people to put the oxygen mask on his face, picked up the oxygen cylinder, and then went down to the submarine, under the command platform is the command room, which is placed with all kinds of operation consoles, and there are a few people in military uniforms lying on the side of the operation platform, Gu Zetong waved his hand, and 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 it with his hand and said, "Send the one alive to the top." ”

When the two soldiers heard this, they carried the unconscious guy outside, and then Gu Zetong said: "Divide into two groups, one group will search forward, and the second group will follow me and search behind, and each group will be equipped with an officer who understands submarines." After Gu Zetong finished speaking, he walked to the cabin in the back, and everyone acted separately.

After passing through the command room, he came to a cabin full of beds, these beds have four floors from top to bottom, and the space on each floor is extremely narrow, and people can only barely turn over when they lie in it, and the officer said to Gu Zetong: "This is the living cabin, there are a total of forty beds, and it seems that the Japanese submarine has more than forty people." ”

The group then walked forward, and behind them was a living cabin, but this living cabin had a separate bed, and the space was also very spacious, and the officer pointed to the cabinet in the cabin with his hand and said to the soldiers: "This is the captain's room, go and open the cabinet, and take away everything with words." ”

After the officer finished speaking, he took out a hemp bag from his backpack and threw it to the soldiers, one of the soldiers took it, opened the cabinet, and stuffed all the paper and notebook inside into the hemp bag, the soldier was collecting information, and the others continued to go forward, and everyone saw two more guys lying on the ground on the edge of the passage, and when they looked over, they found that they were dead, and one of them stretched his hand desperately to the top, as if trying to grasp something on it.

Gu Zetong couldn't help but look up and asked, "What does this devil want to catch when he stretches out his hand?" ”

The officer looked up at the officer, pointed to something like a wrench, and said, "He might want to catch that thing!" ”

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 give me a ladder?" After hearing this, a soldier half-squatted on the ground, patted his shoulder with his hand, and the officer didn't talk nonsense, stepped on the soldier's shoulder and stood up, and quickly jumped down and said: "I understand, that thing is the oxygen regeneration medicine plate switch, and when you pull it, the carbon dioxide can contact the peroxide in it to produce oxygen." ”

Gu Zetong couldn't help but laugh and said: "The little devil is really funny, why should this switch be set at such a high place?" Isn't this embarrassing for yourself? After Gu Zetong finished speaking, everyone laughed, but the officer did not laugh, but said with a straight face: "It's not like this, it may be set up at such a high place to prevent accidental collisions, the cost of oxygen regeneration medicine plates is relatively high, and they can't easily afford it, they may have had accidental collisions before!" ”

Everyone suddenly realized, and the officer pointed to the cabin in front of him and said: "Since they want to open the oxygen regeneration medicine board, it means that there is a lack of oxygen in the boat, and under normal circumstances, oxygen will not be lacking, and the lack is so bad that it makes people unconscious and die, which means that there is a fire in the cabin, and the diesel fuel in the diesel engine room behind is most likely to burn, so everyone should be more careful when entering the diesel engine room." ”

Everyone quickly entered the cabin below, only to see a few "human bodies" lying in it, the reason why it is said to be a human body, because these things only look like people in appearance, the skin has been burned black, like a piece of charcoal, the cabin is full of black ash, obviously there was a fire, the officer nodded and said: "This must be the diesel engine room where the fire occurred, there is nothing to see, let's go back." ”

Gu Zetong said: "Didn't you say that there are more than forty people on this ship? But what we see now is only about 20 or so, and where are half of them? Is it all concentrated in the back cabin? ”
