Chapter: 5412

Wanbao Army soldiers were seen moving three near-defense cannons from container boxes into the open, and Lang Hong Jun looked at them with a mixture of surprise and awe. He had heard Wanbao Army mention this before, asking him to help test-fire these defenses. Although he knew nothing about weapons, he was very familiar with electronic technology-related techniques.

This is Lang Hong Jun's first time seeing near-defense cannons up close. Before, he thought they were just big machine guns, but when he saw them in front of his eyes, he realized that they were actually so massive, especially the six arms-thick gun barrels that looked both rough and long, giving off a sense of grandeur.

The entire near-defense cannon looked like a tank's cannon turret part, with a movable muzzle and a rotating base plate, making its fire coverage range very wide.

Lang Hong Jun watched Wanbao Army soldiers assembling without stop, unable to help but ask Wanbao Army beside him, "Wanbao Master, can one just casually buy such a vicious weapon now?"

Wanbao Army nodded, saying casually, "In Eastern Europe, it's basically just that."

Lang Hong Jun asked in surprise, "Don't anyone care?"

Wanbao Army shook his head and laughed, saying, "These things don't care about here; private transactions also don't care. All sorts of armed groups from Africa use their weapons and equipment, mostly bought from here."

Lang Hong Jun said, "I can understand buying an AK47, but is it too much to buy near-defense cannons...?"

Wanbao Army pointed to one of the near-defense cannons and laughed, saying, "This thing is also an AK, just with a bigger barrel diameter, thirty millimeters."

As he spoke, Wanbao Army nodded his head and said to Lang Hong Jun, "Lang Big Brother, I have a question to ask."

Lang Hong Jun hurriedly said, "Go ahead."

Wanbao Army opened his mouth and said, "Look, I plan to deploy these three near-defense cannons in the glass houses on top of the three observation points, install them simply, and then use helicopters to lift them up. The roofs of the glass houses can all be opened, but this thing requires high installation requirements to ensure shooting accuracy and no malfunction. When using it on the road, it must be securely fixed on a concrete foundation with rebar, which is not difficult, but Mr. Ye hopes I can quickly withdraw these three near-defense cannons after use, and the faster the better. How can I achieve this? Manual disassembly would take quite some time, but once this thing really opens fire, I won't have much time to evacuate it. Do you have any way to let me disassemble it in one minute and lift it away with a helicopter?"

Lang Hong Jun circled his jaw and walked around the near-defense cannon, then opened his mouth and said, "The requirements for using this thing are just to use heavy-duty bolts to secure it, ensuring that it doesn't shake during shooting."

Wanbao Army nodded his head, saying, "That's right!"

Lang Hong Jun thought for a moment and said, "If you can buy these things, then buying a few explosive bolts shouldn't be a big problem?"

"What are explosive bolts?" Wanbao Army curiously asked.

"For aerospace use," Lang Hong Jun said. "You know about multi-stage rockets? It's just three-stage rockets connected together, launching at first with one stage firing, and then when it reaches a certain height, the fuel consumption of the first stage is almost depleted, and it needs to quickly realize separation from the second stage rocket. Then the second stage rocket will quickly fire again, but the requirement for the connection of this rocket is very high, and its rapid separation requirement must be completed in an instant. Therefore, aerospace scientists have invented a type of explosive bolt that is essentially a heavy-duty bolt with a blasting device and ignition device inside. When needed, all you need to do is send an electric signal, and the entire bolt can be blasted apart, allowing for instantaneous separation."

Wanbao Army recalled the image of rocket launches and suddenly realized, saying out loud, "I understand now, that thing is indeed fast! Usually, the booster separates in an instant and blows open."

"Ah, yes!" Lang Hong Jun nodded and said, "This thing is very precise, ensuring that it only explodes itself without damaging the equipment connected to it. It's not just used in rockets; even fighter pilots' ejection seats rely on it for instantaneous separation."

As he spoke, Lang Hong Jun added, "You can use explosive bolts to secure this three-barrel cannon. When needed, you can just detonate the bolt and have this thing detach from its base. If you want to do it faster, prepare a tow rope in advance, and when the time comes, blow up and separate, then airlift the whole thing away directly."

"Great idea!" Wanbao Army was excitedly gripping his fists and exclaimed, "Thanks for the suggestion, Lang big brother! I'll arrange for someone to go purchase it right away."

Meanwhile.

The capital of Northern Europe is Oso City.

Zhou Youguo, who had parted ways with Ding Yuan Bo Yun like a song, was sitting in a bar in Oso City sipping a drink. JrNovels.com
