Lin Yuan thought as he walked down the city, and then saw a group of people around the city gate, and there was a donkey cart in the middle of the crowd.

A Qing soldier was getting down from the donkey cart, and said as he got down: "I heard that the little devil planted a mine, and Lao Tzu specially dug one back to open your eyes!" ”

Lin Yuan suddenly thought of something, and shouted at the group of people from afar, "Get out of the way!" Far from that mine! ”

Everyone knows Lin Yuan, and Shangguan's words are supposed to be unavoidable, but what Lin Yuan said is inexplicable, that mine is put on the donkey cart in a good manner, and no one steps on it, how can it explode?

Lin Yuan saw that everyone was stunned there, so he shouted: "Run for me, run as fast as you can!" ”

When everyone saw Lin Yuan's anger, they hurriedly ran over, and everyone just ran to Lin Yuan's side, only to hear a loud "boom" on the donkey cart, and the mine really exploded. The donkey was covered in blood and fell to the ground screaming, and the donkey was surrounded by broken planks and scattered wood chips.

The Qing soldier who brought the mine back was so frightened that he couldn't speak clearly, and stammered and asked, "Lin, Lin Shuai, how did you know that this mine was going to explode?" ”

Lin Yuan smiled: "Let me ask you, how did you find the place where the mines were buried?" ”

The soldier froze and said, "We went on patrol this morning, borrowed a donkey cart from a fellow countryman, and thought that we could hurry up this way, and when we arrived at the edge of the Japanese minefield, we saw that there were footprints in the snow, and there were traces of digging on the snow. ”

Lin Yuan said: "Why didn't you think about it, did that devil bury mines for you to dig?" ”

The soldier thought for a while and said, "We just think that the devil didn't think about it when he planted the mine, so we forgot to clean up the footprints, and besides, no one has ever heard that a mine will explode after it is dug up!" ”

Lin Yuan said: "That's not a mine at all!" ”

Everyone looked at each other, and one soldier asked, "What can be made by digging out of the ground?" ”

Lin Yuan said: "It's a time bomb buried in the ground, waiting for you to dig it, and it will explode after a while!" ”

Only then did everyone understand that Lin Yuan saw that no one was injured, and ordered them to go back and pass on the word to each other, and not to touch the Japanese mines casually. At this moment, Chen Fei walked over with his hands behind his back.

Chen Fei looked at the donkey on the ground with more breath and less breath, and said with a smile: "It seems that the food will be improved today!" ”

Everyone laughed loudly, and Lin Yuan told everyone to disperse, and everyone was busy.

Chen Fei saw that there was no one around, and asked Lin Yuan, "Comrade Captain, what do you think of the little devil's mine array?" ”

Lin Yuan said: "I see that the Japanese minefield is very well laid, they must have prepared snow in advance, and covered the footprints with snow after the mine, so we can't see that the mines were laid in those places at the time." ”

Chen Fei said: "Mines in this era will definitely not use plastic as shells, so we can use metal detectors to find out the mines, metal detectors, you know, is the security guard at the entrance of the railway station to take a wooden plank-like thing, sweep it on people, there is metal on the body, that thing will 'drip' scream." ”

Lin Yuan said: "This thing is not a cutting-edge thing, of course I have seen it." ”

Chen Fei said nonchalantly: "Build dozens of them." ”

Chen Fei said this sentence very easily, as if he was saying something that was too easy to be easy, Lin Yuan smiled helplessly: "How can it be so easy!" We don't even have a single electronic device here, so what are we going to make it for! ”

Chen Fei let out an "oh" and said: "Then it seems that it can't be built, otherwise, let our unmanned reconnaissance aircraft use radar to scan the underground situation, and it will be clear where there are mines?" ”

Lin Yuan once said helplessly: "Don't be whimsical, this kind of thing can't be done at all, a mine is so small, if you want to find it, how high imaging accuracy is needed!" Don't say that our radar can't do it, even the professional remote sensing equipment of the Institute of Geophysics can't! If the mines could be found in this way, there wouldn't be so many undug mines in the world! ”

Chen Fei suddenly realized "oh" again, Lin Yuan said: "Let me tell you one thing, once, I went to visit the army aviation unit, and saw a soldier leading a dog around the helicopter, the rotor of the helicopter was still spinning vigorously, I was very puzzled, and when I asked, I realized that they were using the dog to listen to the sound of the rotor spinning, to estimate the working condition of the reducer, bearings and other parts inside, I was very strange, I thought this can also be heard!" When I asked again, the comrades of Lu Hang smiled and stopped talking. ”

Lin Yuan looked at Chen Fei with a blank look in his eyes, and he didn't say any more, and said bluntly: "What I want to ask is: Do you know how to train dogs?" Let it find the mines underground for us. ”

When Chen Fei heard this, he smiled and said, "You really asked, I did stay in the military dog base for a while, not to mention anything else, I still know how to train military dogs to search for explosives." ”

Lin Yuan said: "Can this method work?" Although I don't know very much, but I also know that different uses of military dogs are to choose different breeds, such as the search for military dogs and for pursuit of military dogs to choose different ways, the former seems to choose a Labrador, the latter choose a German blackback is better, can we find that breed here? ”

Chen Fei shook his head and smiled: "Haven't you heard that sentence?" There are no students with bad grades, only teachers with poor teaching methods, you can see me. After saying that, Chen Fei went to the city to look for dogs.

Soon it was time for lunch, and Lin Yuan was about to eat, when he suddenly saw Wu Yuankai walking in, followed by a servant with a big box.

Wu Yuankai said with a smile: "Lin Shuai, I don't know if you have heard of a sentence: 'Dragon meat in the sky, donkey meat in the ground', a donkey died at the gate of the city today, I specially asked my subordinates to pick up the good meat on the donkey, cook it with heart, and now I specially send it to Lin Shuai!" ”

Lin Yuan thought to himself: "As a general, you must share weal and woe with the soldiers, it is not easy for the soldiers to be full, how can you eat meat?" I just wanted to refuse, but Wu Yuankai ordered the servant to put down the plate and leave.

At this moment, Chen Fei came in from outside and said with a smile: "I found a suitable dog, and I also went to the scene of the explosion to see, it seems that the Japanese explosives are not very sufficient, they use black powder in their mines, and it just so happens that we also have black powder here, so it should not be a big problem to train dogs to search for mines." ”

As he was talking, Chen Fei saw the big box at a glance, he opened the box at once, and the strange fragrance was overflowing, Chen Fei reached out and tore a piece and put it in his mouth, and exclaimed: "Our ancestors' craftsmanship is so good, I have never eaten such a delicious thing." ”

Lin Yuan said: "If we eat it, the soldiers should not be happy." ”

Chen Fei looked at the box and said, "It's good that you don't eat it!" With this thing, it's a lot easier to train! ”
