Wei Hongpeng said with a smile: "Our infrasound waves are made of bombs. So it's okay to say that an infrasound weapon is a bomb. This bomb has a special structure. The shock wave from the explosion can be converted into infrasound. This infrasound weapon is known as a 'bomb-type infrasound weapon'. It is the strongest infrasonic weapon of all kinds. We are now using 'tubular infrasound weapons'. out of the infrasonic wave although the intensity is not weak. But it's much inferior to it. ”

Chen Fei nodded. The first time to update and then asked: "Then what do these things have to do with construction machinery?" Why do you want to mobilize a batch of construction machinery? ”

Wei Hongpeng said: "The principle is the same as when we dig a pit with a shovel. Let the infrasound waves propagate underground. Spread underground. There is no need to go through the interface between air and land. Avoid the loss of sound waves at the interface between different media. Last time we just put a few sound arrays in the ground. So just dig a hole with a shovel. But this time we're going to put the bomb in the ground...... So it is necessary to call in construction machinery. ”

Only then did Chen Fei understand. At this time, an officer came over and said to Wei Hongpeng, "Report to the commander." The infrasound weapons emplacement point has been prepared. ”

Wei Hongpeng smiled and nodded. Said: "Very good. Let's get started. After Wei Hongpeng finished speaking, he said to Chen Fei: "Let's go out first." Let them plant bombs. Chen Fei agreed. Follow Wei Hongpeng out of the cabin. At this time, a soldier came over in a transport car...... Bring the transporter closer to the cabin.

The bomb weighed seven tons. Therefore, it cannot be transported by manpower. To solve this trouble. Transport rails and motors are specially set up in the cabin. Bombs can be delivered directly to the transporter. The bomb was sent to the transport vehicle. The transport truck drove to the emplacement point. Drop the bomb. The engineering team then filled in the soil back to the laying point.

Although the fighters were very skillful in their operation. But ten bombs could not be planted in an instant. Wait until the deployment is complete. It was already dark.

When Chen Fei and Wei Hongpeng planted infrasonic bombs. The British soldiers in the opposite tower also noticed. At the time of the last deployment of infrasound weapons. Because Chen Fei asked Wei Hongpeng to take camouflage measures. So the British soldiers on the opposite side could not perceive it. But this time it's a truck. It is also excavators and other construction machinery. It's impossible to disguise yourself.

The British soldiers in the tower immediately reported the movement of the middle camp to McMiller. At this time, McMiller was inside the underground command post. Waiting for the attack of the Chinese. Immediately go up to the tower when you get the news. Stand on the tower and look out at the middle camp. I saw that the camp was busy.

Because Wei Hongpeng set up a camouflage net outside the bomb laying point. So McMiller didn't see the bomb planted. McMiller saw only a large number of construction machinery. More and faster chapters are here.

McMiller couldn't help but say to his subordinates: "Why are there so many construction machinery." The Chinese probably want to dig a tunnel from the ground. ”

McMiller's men were not ignorant of military engineering. He shook his head and said, "I don't think it's possible." Digging tunnels is complex. Will the Chinese choose such a way? ”

McMiller nodded approvingly. More and faster chapters are here. "I don't think it's likely, either. All right. Let's not guess. Order brothers. Be ready for battle. ”

The British, on their part, were unaware of the impending death soundwave. Wei Hongpeng's subordinates had already prepared the detonation device. Wei Hongpeng's subordinates reported: "Troop commander. We've calculated the rearward safety distance. This distance is about 1ooo meters. Our personnel should retreat to 1ooo meters away. ”

Wei Hongpeng nodded and replied, "Okay." I'll know the update as soon as possible. Then he said to Chen Fei: "Although the infrasonic bomb has been designed with sound wave direction. However, some of the sound waves are still scattered in all directions. So we should retreat now. ”

Chen Fei asked, "Are we just going to just withdraw the personnel?" It's okay to leave the equipment inside. ”

Wei Hongpeng thought for a while and said, "It's okay for our equipment to stay inside. More and faster chapters are here. However, I am not sure about the construction machinery of the division's engineering regiment. It is not known that the critical vibrational frequencies of their key components are not within the firing frequency of our infrasonic bombs. ”

"Vibration" is an intrinsic property of objects in nature. Many parts of machinery have "critical vibration frequencies". at this frequency. Parts have the greatest vibration amplitude. If the vibration amplitude is large, the equipment will be damaged. That's why Wei Hongpeng asked such a question.

Chen Fei waved his hand and called the commander of the division's engineering regiment to the front. More and faster chapters are here. Asked: "What is the vibration frequency of your construction machinery parts?" ”

After all, the engineering regiment is a user of weapons and equipment. Not a developer. So it's hard to know such a thing. Really. The head of the regiment was confused when he heard Chen Fei's question. asked, "Senior Commander Chen." What do you mean by question? ”

Chen Fei also thought that it was impossible for him to know about this matter. I didn't ask any more. Wei Hongpeng said on the side: "Otherwise, we will let the construction machinery withdraw." ”

Chen Fei pointed to the opposite side with his hand. "It's nothing to get them out," he said. But I'm afraid that the British on the other side think we're retreating. Come and fish in troubled waters. ”

Wei Hongpeng looked embarrassed. Chen Fei waved his hand. Lang Sheng said: "No matter how much. I'm in charge of this matter. I'm responsible for what happened. The entire crew was ordered to retreat. Construction machinery remains. The retreat time was set at three minutes. Three minutes later. Detonate an infrasonic bomb. ”

Chen Fei's order. And they began to retreat. Three minutes later. The soldiers66 continued to withdraw from the barracks. Wait until all the troops are in the safe area. Wei Hongpeng ordered loudly: "Prepare to detonate." ”

One of the operators pressed the detonation button. Chen Fei only heard a muffled "bang" coming from a distance. These are audible sound waves from the explosion. Then there was no sound. The operator looked at the screen in front of him and said, "Report to the troop commander." Infrasonic Bomb No. 1 was successfully detonated. The measured infrasonic intensity is 85% of the theoretical value. ”

Wei Hongpeng nodded with satisfaction. He said to Chen Fei: "If the measured infrasonic intensity reaches 80% of the theoretical value, it means that the infrasonic wave has been successfully generated. We can now detonate the next infrasonic bomb. ”

Chen Fei smiled and said, "That's good." You have full control. ”

Wei Hongpeng immediately gave the order. Ten infrasonic bombs were detonated one after the other. Infrasound silently swooped down on the British soldiers in the underground command post.

McMiller was in the tower when he heard a dull explosion coming from beneath his feet. I couldn't help frowning. I thought to myself, "What is this exploding?" ”
