Open an aircraft carrier to fight against Japan

Yu Ming quickly asked, "What's under the water?"

The engineer replied: "We don't know either. The boat seems to be blocked. The tachometer shows that the propeller keeps turning, but the boat doesn't move forward at all."

Yu Ming first ordered the engineer to stop, and then ordered the divers to go into the water to see. Soon, the divers came back and reported: "One meter below the water, there is an iron cable, and it blocked the boat!"

The method of using iron chains to cross the river to prevent the enemy from crossing the river has been around for a long time. During the Three Kingdoms period, after the fall of the Shu Kingdom, the Kingdom of Wu built a camp near the Xisai Mountain in order to prevent the Kingdom of Jin from going down the Yangtze River from the upper reaches of the Yangtze River in Sichuan. It was intercepted on the river with iron chains, Jin general Wang Jun burned the iron chains, Wu Lord Sun Hao surrendered, and later Tang Dynasty poet Liu Yuxi wrote the poem "Qianxun's iron lock sinks to the bottom of the river, and a piece of sail leaves a stone".

After a while, another diver came to report: "Underwater iron cables were also found in the waters ahead, and a total of twelve iron cables were found within the water area of ​​more than 500 meters!"

These iron chains were laid by the Russians, and the Russian army knew very well that they could no longer retreat. Once the city of Sanxing was lost, there was only Lahasusu left behind. Lahasusu is now Tongjiang. Lin Yuan's troops faced Khabarovsk directly. In that case, all the land invaded by the Russian army in the middle of the Northeast would be returned!

What scares Russia even more is that they don't know that Lin Yuan crossed the border and conquered the territory that originally belonged to the Qing Dynasty?Lin Yuan's power on the Northeast battlefield is so great that people even forget that Beijing still has the Qing court!The attitude of the Qing court was even more ambiguous. Li Hongzhang claimed that he could not see outsiders when he was sick, but the huge prime minister's office could not find a person in charge!

The twelve iron cables were originally used by the Qing army to stop the Russian army, but before they were deployed on the water, the Russian army came, and the twelve iron cables fell into the hands of the Russian army, and the Russian army was in a panic He went to the doctor and used all the methods that could be used to stop Lin Yuan. This passive defense method has been proved countless times in history: it has no effect at all!

Even so, these iron cables still brought countless troubles to Yu Ming, and the one-meter-deep underwater meant that it could block most of the ships transporting supplies and ammunition!

Yu Ming quickly thought of a solution, and he asked, "How is the iron cable fixed?"

The diver replied: "They pierced into the stone wall by the river with iron rods, and the iron cables were connected to the iron rods."

Yu Ming said: "Take a few more people, go down into the water, and pull out the iron rod!"

The diver replied: "I'm afraid this method will not work. I tried to pull out the iron rod when I was underwater, but the iron rod was inserted so deep that I couldn't pull it out at all."

Yu Ming asked again: "What about the connecting part of the iron cable and the iron brazing? Can you find a way to break it?"

The diver replied: "It still doesn't work, the iron cable and the iron braze are melted and cast together."

Yu Ming thought: "Then we can only use explosives, but what I carry is black powder, and I can't use it underwater." After thinking about it, Yu Ming had to contact Lin Yuan. After hearing this, Lin Yuan said: "I will send you people and equipment soon. I will send a boat with three red flags on it. When you see this boat, just lead them to the place where there are iron chains. The rest will be Let them do it."

Yu Ming thought: "Isn't it enough to send explosives that can be used underwater? It's the kind that Deng Hong used to blow up the Yalu River Bridge. Why send a ship?"

A day later, the ship came, and the chimney on the ship was whistling smoke. Yu Ming didn't know any of the people on board. Fade Chen came out of the cabin soon, saw Yu Ming and said with a smile: "Old Yu, I heard that you were blocked by iron cables in the water? Aren't you a fish? Nothing can stop you." Hearing Fade Chen's joke, Yu Ming smiled wryly, and said, "Your joke is so cold, who came here? Why did you even get a boat? It's so troublesome."

At this time, more than a dozen people came out of the cabin one after another. If they were on the Beijing ship, Yu Ming could clearly know who they were, because the clothes of various departments on the Beijing ship were obviously different, but this group of people were all dressed in In this era of fishermen's clothes, how can we know which part they belong to!

Fade Chen said: "The ones who came were from the maintenance team of the Beijing ship. To be precise, they were taking a bath for the Beijing ship." After finishing speaking, Fade Chen laughed a few times.

This confused Yu Mingxiao, and he asked, "What is bathing the Beijing ship?"

Fade Chen hurriedly said, "Keep your voice down, don't let them hear you!"

But it was too late, one of those busy people stepped out, apparently the leader of the group, he stretched out his hand to Yu Ming and said, "My name is Liu Hui, the captain of the underwater hull maintenance team of the Beijing Hull Maintenance Brigade. "

This long list made Yu Ming a little dazed, he nodded and smiled and said, "My name is Yu Ming, Marine Corps."

Liu Hui smiled politely and said, "Scrub the Beijing ship, Comrade Fade Chen, I like your metaphor very much." After speaking, he laughed heartily twice, sweeping away Fade Chen's embarrassment.

Liu Hui said: "Everyone knows that the underwater part of the hull will be attached by various organisms. The temperature, salinity, and the nature and quantity of trace elements in different sea areas are not the same, resulting in a variety of attached organisms. Although the Beijing ship The anti-fouling paint works well, but it still gets stuck with things like barnacles and mussels, and we are responsible for cleaning them off."

Yu Ming understood, he nodded and said: "Oh, so that's what happened." Just after finishing speaking, he understood, and asked: "No! Did the captain send the wrong person? I need to blow up the iron chain. How do you send people to clean up the hull?"

Liu Hui smiled slightly and said, "We don't just clean up attachments."

At this time, several people moved out a machine from the cabin, and a young man ran over and asked, "What task module do we use?"

Liu Hui said: "Module No. [-]!"

The young man nodded, and went back to work with a few people on the machine. Yu Ming asked, "What are you making?"

Liu Hui smiled mysteriously, but did not answer. Fade Chen poked Liu Hui with his hand, and said with a smile, "Don't ask if you shouldn't! Go back and copy the confidentiality code ten times!"

Liu Hui chuckled and said, "We've all reached this age, and there's nothing to keep secret. This is the underwater robot."

Yu Ming let out an "oh", obviously feeling that this answer disappointed him. He didn't know much about military technology, so he didn't think underwater robots were a big deal. In underwater repairs, the visibility is poor and the work intensity is extremely high. Big, divers are prone to fatigue and cannot work for a long time. With underwater robots, it is a milestone for underwater repairs!

Liu Hui went on to say: "Our robot can not only clean up attachments, but also complete tasks such as rust removal, riveting, plugging, etc. It is not an exaggeration to say that even if the propeller of the Beijing ship is blown up, with us, we are guaranteed to be within ten years. It can be fixed in an hour!"

Yu Ming asked again: "What is the second module?"

Liu Hui said: "It is to let the robot complete the underwater cutting operation and cut the iron cable." Yu Ming thought to himself: "Does the captain have to show off his high technology? Wouldn't it be better to just blow up the iron cable with some explosives?"
