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

The engineer replied, "We don't know, the boat seems to be blocked, the tachometer shows that the propeller is spinning, but the ship is not moving forward at all." ”

Yu Ming first ordered the engineer to stop, and then ordered the diver to go into the water to see, and soon, the diver came back and reported: "One meter below the water, there is an iron cable, it is the one who stopped the boat!" ”

During the Three Kingdoms period, after the fall of the Shu State, in order to prevent the Jin State from the upper reaches of the Yangtze River in Sichuan from going down the river, build a camp near Xisai Mountain, and intercept the iron cable on the river, the Jin general Wang Jun burned the iron cable, and the Wu lord Sun Hao surrendered, so that the later Tang Dynasty poet Liu Yuxi wrote the poem "Qianxun iron lock sinks to the bottom of the river, and a piece of sail comes out of the stone".

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

These iron cables were laid by the Russians, and the Russian army also knew very well that they could not retreat any further, and as soon as the three surnamed cities were lost, there would be Lahassusu left, and Lahassusu was now Tongjiang, and as soon as it was lost here, Lin Yuan's troops would directly face Khabarovsk, so that the land invaded by the Russian army in the central northeast would be returned!

What scared Russia even more was that they didn't know how to cross the border and lay down the territory that originally belonged to the Qing State? Lin Yuan's power in the Northeast Battlefield was so great that it even made people forget that there was still a Qing court in Beijing! And the attitude of the Qing court was even more ambiguous, Li Hongzhang said that he was sick and did not see outsiders, and the huge prime minister's yamen could not find a person in charge!

These twelve iron cables were originally intended by the Qing army to stop the Russian army, but before they were laid on the water, the Russian army came over, and these twelve iron cables fell into the hands of the Russian army.

Despite this, these iron cables still caused Yu Ming countless troubles, and the depth of one meter of water meant that it could stop 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 the stone wall by the river with an iron drill, and the iron rope was attached to the iron drill. ”

Yu Ming said: "You take a few more people, go down to the water, and pull out the iron drill!" ”

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

Yu Ming asked again: "What about the connection between the iron cable and the iron drill?" Can you find a way to break it? ”

The diver replied, "No, the iron cable and the iron drill are cast together." ”

Yu Ming thought to himself: "Then you can only use explosives to explode, but all you carry is black powder, and there is no way to use it underwater." Yu Ming thought about it, so he had to contact Lin Yuan, and after hearing this, Lin Yuan said: "I will quickly transfer the people and equipment to you, I will send a boat, there are three red flags on the ship, you see this ship, just lead them to a place with iron cables, and leave the rest to them." ”

Yu Ming thought to himself: "Wouldn't it be enough to send explosives that can be used underwater?" It's the kind that Deng Hong used to blow up the Yalu River Bridge, so why send a boat? ”

A day later, the ship came, the chimney on the ship was smoking, Yu Ming didn't know any of the people on it, it was normal not to know anyone, there were thousands of people on the Beijing ship, and they definitely couldn't know everyone, and soon Chen Fei came out of the cabin, and saw Yu Ming and smiled: "Old Yu, I heard that you were blocked by the iron rope in the water?" Aren't you a fish? How can you be stopped without a net. When Yu Ming heard Chen Fei's joke, he smiled bitterly and said, "Your joke is really cold, who is here?" Why did you get a boat, 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 dress of various departments on the Beijing ship was obviously different, but this group of people were all wearing the clothes of fishermen in this era, how could they know which part of the road they were!

Chen Fei said: "It was someone from the Beijing ship's maintenance team who came, to be precise, to give the Beijing ship a bath. After speaking, Chen Fei laughed a few times.

This made Yu Ming smile confused, and he asked, "What is a bath for the Beijing ship?" ”

Chen Fei hurriedly said, "Be quiet, don't let them hear!" ”

But it was already late, and one of those busy people came out, who seemed to be the leader of this group of people, he stretched out his hand to Yu Ming and said, "My name is Liu Hui, the captain of the underwater hull maintenance detachment of the Beijing Ship Hull Maintenance Brigade." ”

This big string made Yu Ming a little confused when he heard it, he nodded and smiled: "My name is Yu Ming, marine." ”

Liu Hui smiled softly and said: "Give the Beijing ship a bath, Comrade Chen Fei, I like your metaphor very much." After speaking, he laughed heartily twice, sweeping away Chen Fei's embarrassment.

Liu Hui said: "We all know that the underwater part of the hull will be attached to various organisms, the temperature, salinity, and the nature and quantity of trace elements in various sea areas are not the same, resulting in a variety of attached organisms, although the anti-adhesion coating performance of the Beijing ship is good, but it is inevitable that it will be attached by creatures such as barnacles and mussels, and we are responsible for cleaning them up." ”

Yu Ming understood, he nodded and said, "Oh, so that's the case." As soon as he finished speaking, he understood and asked, "That's not right! Did the captain send the wrong person, I need to blow up the cable, how can I send someone to clean the hull? ”

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

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

Liu Hui said: "Module No. 2! ”

The young man nodded, went back and operated the machine with a few people, Yu Ming asked, "What are you getting this?" ”

Liu Hui smiled mysteriously and did not answer, Chen Fei stabbed Liu Hui with his hand on the side, and said with a smile: "Don't ask what you shouldn't ask!" Go back and copy the rules of secrecy ten times! ”

Liu Hui smiled and said: "We have all reached this era, and there is nothing to keep secret, this is an underwater robot." ”

Yu Ming said "oh", obviously feeling that this answer made him very disappointed, he didn't know much about military techniques, so he felt that underwater robots were no big deal, in underwater repairs, visibility was very poor, the work intensity was extremely high, divers were easily fatigued and could not work for a long time, with underwater robots, for underwater repairs, it was simply a milestone leap!

Liu Hui continued: "Our robot can not only clean up the attachments, but also complete the tasks of rust removal, riveting, plugging leaks, etc., it is no exaggeration to say that even if the propeller of the Beijing ship is damaged, with us, it is guaranteed to be repaired within ten hours!" ”

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?" Isn't it good to blow up the wire with some explosives? ”
