Shen Wanqing asked, "Then have you come up with any good solutions?" ”

Lin Yuan shook his head and said, "I haven't figured it out after thinking about it for a long time, and I was just about to ask you, since you're here, you can help me figure out a way." ”

What Lin Yuan didn't expect was that Shen Wanqing actually laughed "Ha Luha", and she was about to laugh out of her tears, Lin Yuan asked in wonder, "Why are you laughing at Lu?" What's so funny about this? ”

Shen Wanqing said: "The method of punching is very simple, you are so smart, there are so many methods, you didn't expect it, and you thought about it for a long time, do you think I can not laugh?" ”

When Lin Yuan heard this, he immediately asked, "Then you tell me, how can you punch holes?" ”

Shen Wanqing smiled: "Of course I used a cutting machine......

Lin Yuan immediately said: "Didn't I already say that the cutter is not good?" That thing is not only very loud, but also requires a large gas cylinder and power supply when it is used, and it will definitely not work with a cutting machine, Wanqing, don't be kidding, hurry up and find a way to come out. ”

Shen Wanqing said: "Who said we have to get the cutter into the crater to punch holes? Why don't we make holes in a fuel tank in advance, then put the dye in it, and then have people take this modified tank and secretly sneak up to the tank and change it? ”

Lin Yuan hurriedly said: "So that's the case, I didn't expect it, okay, let's go and test it." Although it was already late at night, the technical team was still working overtime to repair and improve the equipment, Lin Yuan came inside, found the comrade in charge of cutting the technique, and said to him: "I want a tank tank with holes." ”

The responsible comrade didn't ask too much, so he took a tank fuel tank, then moved the cutting machine out, and asked: "Lin Shuai, do you want to punch a hole, how big a hole do you want to punch?" ”

Lin Yuan thought to himself: "I really haven't thought about this, the size of the hole is also very important, if this hole is too big, it will have no effect, because the dye will leak before you get out of the minefield; If the hole is too small and the dye leaks too little to be effective at all, then how big should the hole be? I guess I can do the math. ”

Lin Yuan silently calculated in his heart: "The dye is a fluid, and the speed that flows out of the hole must conform to the laws of fluid mechanics, fluid mechanics, this is a compulsory course for pilots, and I got the highest score when I was studying." Lin Yuan took out the communicator, looked up a few formulas, then brought the data in and calculated, and said, "Let's make a five-millimeter hole and come out." ”

The comrade in charge nodded, and then said: "I'll let the cutter warm up for a while." At this time, Shen Wanqing said: "I suddenly thought of a question, you said that if the Russians didn't transport the tanks away immediately after we loaded them, wouldn't the dye run out?" ”

Lin Yuan smiled: "You don't have to worry about this, I've already thought about it, the tank is now planted in the mud with its head down, so we will punch holes on the side of the fuel tank, so that the dye will not leak out, but when the Russians put the tank flat and start transporting it back, the dye will definitely leak out." ”

Shen Wanqing asked again: "What if the dye does not flow to the ground, but flows on the body?" ”

Lin Yuan said: "I also reconnoitred, the turret turned an angle, and the fuel tank in the tail was just aimed at the ground. ”

Shen Wanqing nodded, the responsible comrade was also ready, so Lin Yuan asked the responsible comrade to make a hole above the fuel tank, and then found a tank to experiment, and found that there was still a lot of dye left in the distance from the minefield, Lin Yuan was relieved, and now he just waited for the dye to arrive, and he could send someone to install it.

Lin Yuan got the fuel tank and asked people to inquire about the movements of the Russian army, and the person who came back reported: "The Russian army has not moved, and it has not let people come out to continue to get the tanks back." Lin Yuan thought to himself: "After all, the number of their cars is still too small, and it will take a long time for them to transfer the next one after I blow them up." ”

Early the next morning, someone came to report to Lin Yuan, saying that the dye had been delivered, Lin Yuan hurriedly went to get it, and when he arrived at the place, he unscrewed the lid of the bucket and found that it was wrong, he had seen the dye before, and now this dye is very different from the original, the original is bright orange-yellow, and now it has become a transparent color, Lin Yuan thought: "This can't be water." ”

Lin Yuan sniffed it lightly and found that this liquid had a strange smell, it was definitely not water, Lin Yuan couldn't help but wonder what this thing was? He called his comrades in the convoy and asked, "Is this thing a dye?" ”

The comrade replied, "Like." ”

Lin Yuan frowned and asked, "What do you mean?" ”

The comrade said: "I have also heard of this dye, but I did not take it from the original place, but specially gave it to me by the political commissar Han. ”

Lin Yuan thought to himself: "What the hell is going on?" At this moment, Shen Wanqing walked over from a distance, saw the comrade and asked, "Did you bring something?" ”

The comrade pointed to the vat in front of him with his hand and said, "It's all here." ”

Shen Wanqing smiled and said, "Okay, thank you very much." The comrade also smiled and said, "I have something else." After speaking, he turned around and left, Lin Yuan listened to Shen Wanqing's meaning, as if she knew this dye very well, so he asked her, "What?" Do you know what's going on with this thing? ”

Shen Wanqing nodded and said with a smile: "Of course, this kind of thing was sent by Political Commissar Han by me." ”

Lin Yuan asked, "What about my original dye?" ”

Shen Wanqing said with a smile: "I thought about it for a while, your kind of dye is too obvious, the enemy will definitely realize that they will show the way when they see them sprinkled on the ground, so I changed a dye for you, this dye reagent is sprinkled on the ground, and there is nothing abnormal from the appearance, but under the irradiation of infrared rays, there will be obvious bright colors, don't our tanks have infrared searchlights?" At night, when you take a photo of it, you can know the route of the minefield. ”

Lin Yuan said: "That's great, let's find someone to replace the fuel tank!" The job of changing the tank was simple, and it was not difficult for our people to get to the vicinity of that tank, so there were no problems. Lin Yuan sent a reconnaissance team to replace the fuel tank with the tank.

After the change, Lin Yuan began to wait for the Russians to get the tank away, Lin Yuan didn't wait for much time, just after the change at night, a large group of Russians came to the side of the tank during the day, this time they got two cars, one end of the cable made of steel wire was tied to the tank, the other end was tied to the car, and then started the car, in fact, the tank just had its head stuck in the mud, as long as the head was pulled out of the mud, the tank itself could come up from the bottom of the crater, and the two cars pulled it, and the tank immediately walked out of the pit.

As soon as the fuel tank was flattened, the dye began to leak, Lin Yuan called the infrared picture to see, the dye was displayed as bright red under the infrared image, and Lin Yuan knew that the dye had taken effect. The Russians' cars quickly pulled the tanks back to their own camp, indicating a conspicuous path in the minefield.

Lin Yuan immediately decided to break through the minefield in the early morning of October 6 and conquer the Russian positions in Kent Mountain!
