Lang Hongjun said: "I can still understand buying an AK47, isn't it a bit arrogant to buy a close-in anti-aircraft gun..."

Wan Pojun pointed to one of the close-in anti-aircraft guns, and said with a smile: "This thing is also an AK, but the caliber is a little bigger, 30mm."

Saying that, Wan Pojun smacked his lips and said to Lang Hongjun, "Brother Lang, I have a question for you."

Lang Hongjun hurriedly said, "Say it."

Wan Pojun opened his mouth and said: "Look, I plan to arrange these three close-in anti-aircraft guns in the glass room at the three commanding heights above. It can be opened, but the installation requirements of this thing are very high. To ensure the accuracy of shooting and no drum obstructions, when using the roadbed, it must be firmly fixed on the reinforced concrete base. It is not difficult to fix, but Mr. Ye I hope that I can quickly withdraw these three close-in defense guns when I'm done using them up, and the sooner the better, how can I achieve it? I'm afraid it will take a long time to manually disassemble and assemble, but once this thing is really fired, I don't have much time to evacuate, is there any way for me to dismantle it within a minute and lift it away with a helicopter?"

Holding his chin, Lang Hongjun walked around the anti-aircraft gun, and said, "The requirement for this thing is to fix it with heavy-duty bolts to ensure that it does not shake when shooting, right?"

Wan Pojun nodded: "Yes!"

Lang Hongjun thought for a while and said, "If you can even buy this thing, then it shouldn't be a big problem to buy a few explosive bolts?"

"Explosive bolt?" Wan Pojun asked curiously, "What is that for?"

Lang Hongjun said: "Aerospace is used for multi-stage rockets, right? To put it bluntly, a three-stage rocket is three rockets connected together. When launching, the first-stage rocket is ignited first. After reaching a certain altitude, the fuel consumed by the first-stage rocket It�s almost there, and it is necessary to quickly realize the separation from the second-stage rocket, and then the second-stage rocket will ignite and fly quickly, but the solidity requirements of the rocket�s connection are also very high, and its rapid separation requirements must be completed in an instant, so aerospace Scientists in China invented a kind of explosive bolt. To put it bluntly, the heavy-duty bolt has a built-in blasting device and an ignition device. When needed, as long as the electricity is turned on, the entire bolt can be directly exploded, and then it can be separated instantly."

Wan Pojun recalled the scene of the rocket launch, suddenly realized, and blurted out: "I know, that thing is really fast. Generally speaking, when the booster is separated, it explodes in an instant."

"Yes!" Lang Hongjun nodded, and said: "This thing is very precise, and it can ensure that only itself will be blown up, and the equipment connected to it will not be damaged. It is not only used for rockets, but also for the escape seats of fighter pilots. With that, the hard connection can be undone in an instant.�

Speaking, Lang Hongjun said again: "You use explosive bolts to fix these three cannons. When necessary, you only need to detonate the bolts, and this thing will be separated from the base. If you want to go faster, you should prepare the slings in advance. When the time comes, the explosion will be disconnected, and the helicopter will hang up the sling and take it away directly."

"Good idea!" Wan Pojun clenched his fists excitedly, and blurted out, "Thank you Brother Lang, I'll arrange for people to go shopping."

at the same time.

Osu City, the Nordic capital.

Jiangong Bo Ou Bojun, who had already parted ways with Dingyuan Boyun Ruge, was sitting in a bar in Aosu City drinking.

In the past few days, he started from Bergen and investigated all the way, wanting to know where the missing cavalry guards went, but he has not found any clues related to them.

In fact, when he was in Bergen, he thought about two directions.

Since I am on the line of Cha Xiao's cavalry guards, on the one hand, I can find out where the Xiao Xiao cavalry guards went after Bergen disappeared, and on the other hand, I can also find out what special circumstances the Xiao Xiao cavalry guards had before they came to Bergen .

Among them, the former is naturally the best choice.

Because only by finding the whereabouts of Xiaoqiwei, can we know who rescued Lin Wan'er.

As for the latter, we can only hope that there are some shady problems in Xiaoqiwei himself, otherwise, it is basically a waste of time to check this line forward.

Therefore, Ou Bojun took the lead in choosing the former, and checked in Northern Europe for several days.

I searched all the way to Ausu City, but still haven't found any clues.

When he was depressed, he simply found a bar in Osu City and had a drink.

However, just when he felt a little bit drunk, his mobile phone suddenly received a message from a virtual number, the content was only six short words: the meeting will be held in half an hour.

He reluctantly put away his cell phone, took out two banknotes and put them under the wine glass, got up and walked out of the bar.

Back at the hotel where he was staying, Ou Bojun washed up and opened a special software on his phone on time. JrNovels.com
