Catastrophe

Zhou Gong heard Ren Jiao's question, and shook his head worriedly: "The characteristics of infrasound waves are that they have a wide source, spread far, and can travel far around obstacles. Infrasound waves with a frequency below 1 Hz can reach thousands of people. As far as tens of thousands of kilometers away, it can not only penetrate the atmosphere, sea water, soil, but also penetrate solid reinforced concrete buildings, even tanks, warships, and submarines.

The infrasound wave here is too strong, so strong that it can kill animals in seconds. Without professional equipment, it is difficult for us to resist it. If the infrasound resonates with the surrounding objects, it can release considerable energy. The sound wave of 7 kHz uses a Paper can block it, but infrasound waves of 7 Hz can penetrate reinforced concrete more than ten meters thick, which is the main reason why infrasound waves can ignore the jungle environment and drive away animals. "

Zhang Fang frowned: "That is to say, even if we hide behind a mountain, is it difficult for us to avoid this kind of infrasound attack?"

"Theoretically, this is the case! If we want to avoid the attack of infrasound waves, unless we are in a special room or in a vacuum environment, in theory, if we can build a wall with a lot of vacuum kettles, It can withstand the attack of sound waves, but the environment we are in now seems to be unable to create a vacuum environment.”

Ning Zhe heard that infrasound was so terrifying, and clenched his fists and said, "Zhou Gong, since you understand the principle of infrasound, I believe you can find a solution. The safety of so many of us is all in your hands. !"

Seeing that everyone was looking at him, Zhou Gong responded nervously: "As of now, we can only gamble, I do have a way, but my way may not work, and there is only one chance, if we Do it my way, and if something goes wrong, it's a gamble with everyone's life!"

Ning Zhe looked at the tired-looking people around him, and said seriously: "We keep running away now, death is the only ending, let's bet, we still have at least a glimmer of hope! Zhou Gong, tell me, we What should I do?"

"If my thoughts are correct, the infrasound waves in this rainforest are not disordered, but are driving animals forward like a rolling wheel, so it is useless for us to run along it, but against it. Run, get to the back of it, that's the only way to be completely safe!"

Zhou Gong paused: "We have two difficulties now, the first is how to avoid the attack of infrasound waves, and the other one is to see if my bet is correct, if there is only one infrasound wave to gather in one place, then we will We can dodge it, but if it's like a big wave, we're going to have to die."

"According to this momentum, we will be cornered by these infrasound waves!" Ning Zhe made a decision without hesitation: "Just say how we can escape the sound waves!"

"The viscous semi-fluid can absorb and weaken the energy of infrasound waves. We can look for ponds and use mud to block the transmission of sound waves, but this method is not very safe. We have to find a way to create a vacuum. The difficulty now is It's about how do we create a vacuum."

"Is it okay to explode?" Zhang Fang looked at Zhou Gong and asked, "It will consume a lot of oxygen when it explodes. Can it form a vacuum?"

"No, the explosion can only be regarded as consuming oxygen and reducing the oxygen content in the air." Zhou Gong thought for a while: "But this method may be tried. Whether it is a chemical explosion or a physical explosion, it is all in a very short time. A large amount of gas is produced in it, and the surrounding gas or other media are expelled, forming waves after waves, so there is sound, and we may be able to use this wave to interfere with the transmission of infrasound waves, as for the effect, I can't judge."

"We are now surviving from death, and when there is no other way to go, this is the only way." Ning Zhe waved to the people around him: "Everyone continue to walk forward, look for the pond, Zhang Fang, Lin Bao, you two catch fish with me!"

Lin Bao said in surprise: "Brother, what time is this, do you still want to have a late night snack?"

"I have my use, everyone act! Quick!"

After Ning Zhe's order was issued, everyone at the scene started to rush and regained their energy.

The most important thing in the rainforest is the pond. Everyone quickly found a puddle that was not too big. Zhang Fang threw a grenade down, and most of the piranhas in it turned white, and the others began to exhaust their resources. The tools began to carry water outside, and drains were dug to divert the water.

In less than ten minutes, a group of people squatted in the muddy pond and waited.

In front of the pond, Ning Zhe had placed a fish, a mouse, a hare or something every five meters, and it spread far away.

About six or seven minutes later, the farthest fish suddenly fluttered twice, and then lost its breath.

More than ten seconds later, the second hare kicked his legs.

Lin Bao felt the pressure from his internal organs again, and asked Ning Zhe, "Brother, you just caught fish just to measure the transmission distance and speed of infrasound waves?"

"That's right, we can't see or touch this thing, so we can only observe it in this way!" Ning Zhe took off the ring of a grenade: "Wait a minute I'll call three two one! When I call two , everyone threw grenades ten meters in front of us, and when the count reached one, everyone hid in the mud and tried to keep their bodies as low as possible~www.readwn.com~ As for whether we can survive, we can only see God's will!"

The infrasound waves were still being transmitted to Ning Zhe and the others. Ning Zhe saw the last fish in front of him died and estimated the time: "Three! Two! One!!"

Six or seven grenades were thrown towards the ground ahead, and then everyone plunged into the mud beneath them.

For a moment, Ning Zhe felt that the pressure of the mud made it difficult for him to breathe, and then he began to poke under the mud hard.

A few seconds later, a strong sense of oppression came from all directions. The huge pressure made Ning Zhe open his mouth and swallowed a mouthful of mud.

At this moment, there was a strong sense of distortion in his five senses and limbs, and a strong sense of pain appeared again in his limbs.

The intense pain made Ning Zhe nearly faint, and subconsciously activated his violent ability to resist.

Normally, when people hide in the mud, they should hold their breath and resist, but this kind of pain makes people unable to control themselves at all. Ning Zhe opened his mouth wide and tried to inhale, but he only ate all the mud in his mouth. Under the condition of suffocation , the survival instinct made him straighten his body subconsciously, wanting to go up to breathe.
