Zhang Shouen was stunned for a moment and asked, "Lin Shuai, what do you want to disassemble the cannonball?" ”

Lin Yuan said with a smile: "We have to replace the charge inside, that's why I want you to take the black powder charge cannonball, the black powder can be poured out, and the black ladder mixed explosive is heated and melted and put in, and it is solidified inside, and we have no way to replace it." ”

Several fighters took out the disassembly tools and took a lot of effort to disassemble the warhead, revealing a full load of black powder.

Lin Yuan said: "Pour out three-quarters of the black powder inside." Then he said to Liu Yufeng and his subordinates: "You guys, go and grind this graphite into powder." ”

Everyone didn't know what Lin Yuan wanted to do, but they knew that Lin Shuai explained the reason to them, and they didn't understand, so they simply didn't ask anymore and went to work.

At this moment, Chen Fei came over to find Lin Yuan, and when he saw this hot labor scene, he asked with a smile, "What are you doing here?" ”

Lin Yuan smiled: "I'm making new weapons. ”

Chen Fei said "um" and said, "I'm here to tell you that Xu Feng has returned to Hunchun City." ”

Lin Yuan asked in surprise, "What is he going to do when he goes back?" Why are you in such a hurry? ”

Chen Fei said: "He said that there are still his people in the city, and he wants to go back to join us inside and outside, and he heard that the Russian army is going to close the city, so he left in such a hurry." ”

At this time, Zhang Shouen came over and asked, "Lin Shuai, according to your request, three-quarters of the black powder has been poured out, what will you do next?" ”

Lin Yuan saw that Liu Yufeng hadn't finished it yet, so he said, "Wait until Liu Yufeng finishes grinding the graphite." Chen Fei looked at Zhang Shouen and Liu Yufeng, and said with a smile: "I know what new weapons you are going to make, you want to make carbon fiber bombs, right?" ”

Lin Yuan smiled: "Do you still know about the carbon fiber bomb?" It's not easy! ”

Chen Fei said: "Although I don't know as much as you, I have also heard of this kind of bomb, which is specially used to deal with power generation systems, but ......"

Speaking of this, Chen Fei frowned slightly, and Lin Yuan asked, "What did you think of?" ”

Chen Fei said: "Your approach is too rough, isn't it? Does it work? ”

Lin Yuan said with a smile: "Compared with ordinary bombs, carbon fiber bombs mainly need to consider three problems, the manufacture of carbon fiber, the opening of the warhead and the throwing of carbon fiber regiments, these three problems I have solved with soil methods." ”

At this time, Liu Yufeng came to Lin Yuan with a box of ground graphite powder and asked, "Do you think this is okay?" ”

Lin Yuan said: "Grind it finer." ”

Liu Yufeng then went back to grinding, and after a while, Lin Yuan said: "Load all these graphite powders into the shell warhead." ”

Zhang Shouen led the soldiers to load the graphite powder into the warhead, and Lin Yuan waved his hand to everyone and said, "Let's go, let's try this cannonball." ”

When everyone came to the shooting range, Zhang Shouen ordered his subordinates to bring an 82-mm mortar, dig a shallow pit in the ground, and then put the mortar's seat into the shallow pit, open the bipod on the gun, and ask Lin Yuan: "Lin Shuai, where are we aiming?" ”

Lin Yuan said with a smile: "You don't need to aim at the target, just hit it at will." ”

Zhang Shouen personally operated the artillery, put the shell into the cannon body, "boom", the shell flew out of the muzzle, fell to the ground and made a "bang", after the sound, the shell actually poked straight on the ground, did not explode!

Zhang Shouen frowned and said, "This may be a bad bomb!" ”

Lin Yuan got up and walked towards the shell, Zhang Shouen hurriedly stopped him and said, "Lin Shuai, this bad bomb may explode at any time, you can't go over, it's too dangerous." ”

Lin Yuan smiled: "It's okay, the shell has exploded, I don't believe you came to see me." ”

Zhang Shouen walked to the cannonball suspiciously, Lin Yuan pointed to the cannonball, and said: "Look at the cracks on the shell, the cannonball didn't explode just because the amount of black powder in it is too small, you go back and make another cannonball, this time change the amount of black powder in the cannonball to one-third." ”

Zhang Shouen went back to do so, and soon made a new cannonball, and tried it again, this time the cannonball was blown up after landing, although a part of the graphite powder was ignited, but there was still a lot of graphite powder floating out.

Lin Yuan said with a smile: "Very good, according to this ratio, make more of these shells, and we will call them graphite shells in the future." ”

Chen Fei said: "If our shells can blow up the transformer, what else do we use graphite powder for? ”

Lin Yuan said: "The range of our shells is not enough, so we must use graphite powder. ”

Chen Fei looked dazed and thought, "Could it be that the range of the cannonball will increase after adding graphite powder?" He wanted to ask again, so Lin Yuan said to him: "Okay, wait until tomorrow and you will understand, let's go back and deploy a way to break through the barbed wire." ”

The next day, after everything was deployed, Lin Yuan led a battalion of troops to the periphery of the transformer, and the Russian army also saw the Chinese troops, so they were heavily guarded. Lin Yuan said to Zhang Shouen: "Replace the instantaneous fuse on the body of the projectile, and this time we will use the time fuse." ”

Zhang Shouen asked, "Lin Shuai, how long is our time fuze set?" ”

The time fuse produced by Lin Yuan's arsenal uses a clock and watch timekeeping structure, that is, the gear turns a certain number of turns to ignite the initiating charge, and when it is used, it can be set at different times according to the different nature of the target. ”

Zhang Shouen set the time fuse of the cannonball, put it into the cannon body, and the cannonball slid down the barrel, making a "bang" sound, and after falling to the bottom, the "boom", the shell rushed into the sky with a terrible whistling sound.

When the shell flew to the highest point, it did not continue to fall, but with a "bang", it exploded in the air, and the graphite powder inside was blown by the wind and fell fluttering on the positions of the Russian army.

Lin Yuan turned his head and said to Chen Fei: "My intention is not to let the shell explode the transformer, but to let it explode in the air, I just calculated the time when the fuse was installed according to the ballistic performance of this shell and the direction of the wind, and the graphite powder after the shell exploded was blown down by the wind on the Russian position." ”

Chen Fei nodded, it turned out that this was the case, and after speaking, he pointed to the transformer and said, "Look, their transformer has not changed at all!" Lin Yuan smiled helplessly: "What is made by soil methods just doesn't work, it seems that the amount of carbon fiber that fell on the transformer of the Russian army is not enough." ”

Chen Fei hurriedly asked, "What should I do then!" ”

Lin Yuan couldn't help but laugh out loud and said, "How can you forget such a simple truth, wouldn't it be okay to launch a few more!" Chen Fei also smiled, Zhang Shouen then fired more than a dozen shells, more and more graphite powder fell on the transformer, graphite powder from the outside of the iron box heat dissipation hole, light graphite powder was adsorbed on the coil of the transformer, graphite is a good conductor, connected between the two coils suddenly formed a loop, instantly generated a huge current, the huge heat generated by the current actually melted the steel coil.

When the transformer is working, a large amount of heat will be generated, and the heat is transferred by the cooling oil inside, but the huge heat directly ignites the cooling oil, and suddenly flames emerge from the iron box of the transformer.
