However, for one second, all helicopter channels were covered by a harsh noise.

From the cabin video, it can be seen that the people in the helicopter didn’t persist for long, and they staggered in this noise until they completely lost consciousness. Some people also had symptoms of vomiting control …
See here all people mind flash across a weapon for the first time.
"Wave!"
Wave weapons may cause this situation.
But the horse was questioned again.
"What kind of wave weapon can cause this effect?"
"You know, those drivers are all wearing flying headphones."
Sen really thought about it and replied, "Maybe it’s not only that we hear noise attacks, but also that we can’t hear superwaves and infrawaves …"
Wave weapons generally include noise, infrawave and superwave.
The noise is close to usual, but you often see big speakers, but the direction of the waves is constrained, so you can attack people in a specific direction in a directional way, but the attack range is usually as short as a few hundred meters.
However, if the frequency of the secondary wave is lower than 2 Hz, the frequency and intensity should be controlled within a certain range, which can make people upset, dizzy, sick and vomiting, and even insane and manic through continuous influence.
Superwave weapon is beneficial to the high-frequency wave generated by high-energy superwave generator, which can also make people have physiological reactions such as blurred vision and nausea. It can even be used to directional mine clearance and detonate mines, mines and torpedoes.
Of these three kinds of wave weapons, the second wave and the superwave are the most concealed, which makes people kill people in shape.
But …
Laopan watched the helicopter crash out of control after losing its pilot in the video.
He covered his eyes and looked at Sen Zhen.
"Even so, it can explain how such a powerful wave attack is formed."
"How does the wave focus on emission and achieve such high intensity in such a vast environment of the sea?"
It seems that this kind of wave weapon has reached an incredible level to defeat Lao Pan with a helicopter pilot hundreds of meters high.
As he said, waves are difficult to focus and emit directionally, and it is difficult to control.
Second, it is difficult to achieve too much power in a rough environment.
The efficiency of three-wave energy transfer to an object is not high, which also limits its lethality to a great extent
In addition, Lao Pan can list a lot of shortcomings of wave weapons. If it were not for these shortcomings, the wave weapons that are the most successful in the realization of the earth would not be driven away by loudspeakers.
Zhang Tianyuan pulled the video progress bar back for a while before the helicopter was attacked and then pointed to a corner of the picture.
"Look, this sea monster came out from here and the helicopter was attacked in a second."
This base can confirm that the wave attack was issued by the third monster.
"I don’t think the problem of Apollo’s weapons’ reality is too deep. That’s a pioneering thing."
This sentence woke Lao Pan up a little.
He patted his head.
Those aliens have even built wormholes. What’s so hard to accept to build a monster with powerful wave weapons?
This world is science fiction enough.
Now it’s enough to make sure that monsters may have this ability.
Understand this problem, Lao Pan re-ordered.
"I am now instructed that the code name of the monster currently attacking Hong Kong [Horn] is supposed to launch a large-scale high-intensity wave attack. Please ask neighboring PPDC member countries to send man-machine to approach reconnaissance …"
Zhang Tianyuan also spoke to Ning Ji Hua and Taylor, "Send more satellites to stare at this monster. Since this monster has wave weapons, it will always float on the sea with great probability."
The two immediately promised to access more satellite images to the base through the pre-determined emergency procedure soon.
In the monster clear image soon returned to the front.
It’s a lizard-like monster. It floats on the sea surface, covered with vertical banded structures from beginning to end, and it also vibrates violently, and the surrounding sea water keeps rolling like it is boiled …
Mori Zhen gave a brief explanation: "According to the current sea surface image, the horn is about 16 meters long, crawling on all fours, and when the back is shaken with a lot of vibration bands, it will send out high-intensity waves around it, covering almost all frequencies."
"What is the killing range of the wave?" Zhang Tianyuan asked
Mori really looked at the eye data. "It has been detected that 13 decibels of noise can still be detected five kilometers away."
Thirteen decibels …
They looked at each other.
Sudden exposure to this decibel volume can cause ear injuries, and it is common for modern medical methods to cure hearing impairment.
Lao Pan’s face is heavy. "Does this mean that the monster can attack the city residents if it is five kilometers near the coast?"
"I’m afraid not."
Mori really shook his head and the horse added.
"The influence range of monster wave has also expanded sharply. It is speculated that the vibration of monster strap will become stronger and stronger with time."
Yeah!
Zhang Tianyuan closed his hands and held himself deep in thought.
Even he thinks this monster is tricky.
Don’t say this is another monster against him.
The pioneer gave up the original work to participate in the final battle monster group.
From this, it can be seen that they have realized that no matter how big the monster is, unless it can withstand falling from the sun, it will not survive an exile when it meets him.
The pioneers have worked out these two monsters.
One head can fly, and if it falls from the middle, it can also glide with the trend.
A wave can attack at any moment, and he can’t get close …
And the attack range of 5 km wave has exceeded the tunnel operation range when it is opened by visual mode.
Even he had to admit that the pioneers really came prepared this time.
It’s not just Zhang Tian’s elder Pan and others who are also worried about this monster.
They also saw that this monster was specially designed to cope with exile.
"Can our current mecha cope with wave attacks?" Ning Ji Hua asked Laopan.
Ranging from Laopan’s answer to Sen Zhen, he robbed, "But all the mecha’s cockpit departments are completely closed, and it is difficult to pass on the energy of weapons."
"Then we will send another mecha back to protect Hong Kong?"
Old Pan Gang came up with this idea and always woke up with Cai Tiantong on the communication channel.
"At present, there are two monsters at the bottom of the sea. They are also five monsters, and it is difficult to fight with the mecha at the bottom of the sea. Let’s leave two mecha …"
No more talking
Everyone knows what the consequences will be.
Even if the land mecha is not necessarily a monster opponent, let alone the underwater, which is the home of monsters.
Leaving two mecha there is different from letting them die, and it is impossible to complete the plan of nuclear attack on wormholes.
But what will the Hong Kong government do if the mecha are not transferred back to defend?
"Then let’s bring the storm back first?" Laopan tried out the suggestion and watched Taylor’s face as he saw that he was extremely dark.
However, Zhang Tianyuan shook his head.
"What about San Francisco if we send the storm back to Hong Kong?"
"That monster can fly. Once it is not destroyed, it will fly somewhere at a time, which may trigger a monster proliferation crisis …"
This problem is the most serious.
Let a flying monster stay on the earth. What if it’s a pregnant individual like the former rat, and it’s specially smuggled into the earth to give birth, so that its child can be an earth beast?
