In 1948, an HL cargo ship named "Ulan Gemmechi" encountered a storm in the Strait of Malacca. When rescuers arrived, all the people on board died inexplicably. After investigation by scientists, they found
The main culprit of their deaths was the infrasound waves caused by storms and sea waves.
The frequency of infrasound waves is 0.0001~20Hz (Hertz), which is inaudible to the human ear. The frequency of subtle pulsations in various parts of the human body is generally 2~16Hz, such as 4~6Hz for internal organs, 8~12Hz for the head, etc.
These natural frequencies of the human body are exactly within the frequency range of infrasound waves. Once high-power infrasound waves act on the human body, they will cause strong resonance in the human body, causing damage.
Infrasonic weapons use infrasound waves with a frequency lower than 20Hz to resonate with the human body, causing the resonant organs or parts to shift and deform, causing damage or even death to the human body.
Infrasonic weapons have the characteristics of strong concealment, fast propagation speed, long propagation distance, strong penetration, and do not pollute the environment or damage facilities. Therefore, they are listed as an important member of the new concept weapon family and are bound to become the new favorite weapons on the future battlefield.
Just because of technical problems, infrasonic weapons have never really appeared on the stage. Countries around the world are also secretly studying infrasonic weapons, but the final results have indeed never been achieved. Who knew that Miss Su would give them a big surprise? No, also
Call it a scare!
"Xiao Su, have you really developed infrasonic weapons?"
It's not that they haven't studied sonic weapons, but due to various reasons, the progress of sonic weapons has been stagnant. Xiao Su is really their lucky star in Xia Kingdom!
"If you don't believe it, we can go outside and test it!"
"No, no, no, we believe you, we definitely believe you!"
They naturally believed in Su Leyan's ability, but they were just too surprised.
"Chief, with sonic weapons, our pressure will be greatly reduced to deal with those tens of millions of zombie legions. Without further ado, should we put this matter on the agenda as soon as possible!"
"Yes, we need to act as soon as possible, who knows what those zombie legions will do!"
Over the past six months, they have finally stabilized the situation, but they cannot let those zombie legions break their current situation.
Moreover, zombies and humans will have a battle sooner or later, but it is only a matter of time.
Zombies evolve faster than humans, but now something unexpected happens, they must act in advance.
"Xiao Su, look at what materials are needed to make sonic weapons. You make a list and we will prepare them for you. If Shuguang Base doesn't have them, I'll go find Mr. Lu and make sure to get the sonic weapons out as soon as possible!"
"no problem!"
"Xiao Su, can we old guys follow you during production?"
"sure!"
Su Leyan nodded nonchalantly. To her, sonic weapons were not a black technology. Even without her, they would be able to figure it out after decades of time.
Hearing Su Leyan's words, several senior experts were overjoyed. After the meeting, they followed Su Leyan directly to the laboratory. Soon, Zhang Jianguo sent all the materials.
Not only weapons experts, but Professor Zhou and others also came to participate. Although they are not weapons experts, they are top physicists. With their joining, the speed will naturally be very fast.
However, in order to take care of several veteran experts and professors, Su Leyan deliberately put in all the steps.
A few old guys discussed privately that Su Letan alone could support a country's scientific research capabilities. One can only imagine how strong Su Letan's abilities are!
Although the survivors at Shuguang Base didn't know what happened, they saw the military area packing their bags and had some guesses in their minds, but they were not afraid. After all, the base had an energy shield and zombies couldn't get in, so they were still safe.
However, some people are still a little worried. It seems that this is another war!
"Su Yan, do you know what happened at the base?"
"have no idea!"
"I always feel like something big is about to happen, otherwise why don't you ask your brother?"
"Even if I asked, my brother wouldn't tell me!"
The army has strict discipline, how could her brother tell her such a thing.
"How about asking Captain Xiao?"
Chen Liang's eyes lit up. His uncle is still the management of the base and is highly regarded by his superiors. He should know something. He did not touch Xiao Ze beside him.
"Cousin, why don't we ask my uncle?"
"My dad is very busy every day and is not at home often, so he may not be able to find anyone!"
Everyone nodded in understanding. Captain Xiao helped Su Leyan manage the base from the beginning. Later, the army came over. Although Xiao Hongfu was no longer the top leader, his status in the base was still high and he was very busy every day.
If you make friends, you may not be able to find someone!
Everything in the base remained as usual. As the troops came in and out, the survivors still felt a sense of an approaching storm. Everyone stopped going out to hunt zombies and hid in the base obediently.
Since the above didn't say what it was, they didn't ask, they just stayed there!
The Gale Team did not get any information from Xiao Hongfu in the end. It seemed that the matter was still kept secret, but they always felt that it would not be too simple this time.
"How about we ask Sister Su?"
"You forgot, my dad said that Sister Su is very busy now and doesn't care about us at all. If we go over at this time, it will just cause trouble!"
"That's true!"
Chen Liang touched his chin, but if he just let them wait here, they would be worried, and they didn't know what was going on this time!
"Then what do we do now?"
"Don't leave Shuguang Base during this period. Just wait and see if there's anything we can do to help!"
"Can!"
There is obviously a problem during this time period. As a well-known team of superpowers at Dawn Base, they had better stay at the base just in case.
After the few people discussed it, they went directly back to the gathering place of their team, keeping an eye on the movements of the military region.
On the other side, Zhou Ying, who had been living in Shuguang Base for ten days, was also very nervous. Shuguang Base was suddenly under martial law. For those who didn't know, she thought she had been discovered.
This time she learned to be smart and did not let the system take action. The last time she came to Shuguang Base, she asked the system to cover up her genes. Unexpectedly, it only took a short moment for the data virus to track her down.
If the system didn't respond quickly, it would be really bad. This is why Zhou Ying didn't dare to let the system scan the Dawning Base!
If 666 hadn't happened to be in the process of being upgraded, the last wild system attack would have been exposed, and the data virus was Su Leyan's work.
The moment the wild system appeared, Su Leyan received the alarm system and immediately carried out the final operation, but was finally escaped by it.
