Lao Pan took the microphone: "Send the video."

Soon, the video was sent to the meeting room.

Lao Pan immediately opened it and found that it had little to do with what Cai Tiantong said.

Among the helicopter queues responsible for tracking and reconnaissance, only some of them hang sonar at low altitudes to detect the location of monsters in the water, but most of them are helicopters responsible for logistics support, flying hundreds or even thousands of meters in the air.

Under normal circumstances, a few hundred meters in the air is already safe enough, especially in this situation where monsters have nothing to throw at sea.

However, in the next second, all helicopter channels were covered by a piercing noise.

Judging from the video in the cabin, the people in the helicopter didn’t hold on for too long, they just swayed amidst the noise until they completely lost consciousness, and some people even showed uncontrollable vomiting symptoms...

Seeing this, a weapon immediately flashed in everyone's mind:

"Sonic!"

Only sonic weapons can cause this.

However, another question was immediately raised:

"What kind of sonic weapon can cause this effect?"

"You know, those pilots are all wearing flying headsets."

Mori Mako thought for a while, and replied: "It may not only be the noise wave attack we heard, but also the inaudible ultrasonic and infrasound waves..."

Common sonic weapons are noise waves, infrasonic waves, and ultrasonic waves.

Among them, the noise wave is similar to the loudspeaker that is often seen in normal times, but the direction of the sound wave is restricted, and it can target people in a specific direction, but the attack range is generally only a short few hundred meters.

The frequency of infrasound is lower than 20 Hz. As long as the frequency and intensity are controlled within a certain range, it can make people upset, dizzy, nausea and vomiting, even unconsciousness and madness through continuous impact.

Ultrasonic weapons use high-energy ultrasonic generators to generate high-frequency sound waves, which can also cause physiological reactions such as blurred vision and nausea.

Among these three kinds of sonic weapons, infrasound and ultrasonic waves are the most concealed, killing people invisible.

but……

Lao Pan looked at the video, and the helicopter in it lost control and crashed after losing the pilot's control.

He covered his eyes and looked sideways at Mori Mako:

"Even if this is the case, it cannot explain how such a powerful sonic attack was formed."

"How is the sound wave focused and emitted, and how can it reach such a high intensity in such an open environment like the sea?"

To be able to defeat a helicopter pilot at an altitude of hundreds of meters to a thousand meters at once, in Lao Pan's opinion, this sonic weapon has reached an incredible level.

As he said, sound waves are difficult to focus and emit in a directional manner, and it is difficult to control them.

The second is that it is difficult for sound waves to achieve too much power in an open environment.

Third, the efficiency of sound waves to transmit energy to objects is not high, which also limits its lethality to a large extent.

In addition, Lao Pan can also list a lot of shortcomings of sonic weapons. If there are no such shortcomings, the most successful sonic weapon in practical use on the earth now would not use a loudspeaker to drive people away.

Zhang Tianyuan pulled back the progress bar of the video for a while, before the helicopter was attacked, and then pointed to a corner of the screen:

"Look at the surface of the sea, the monster came out from here, and the helicopter was attacked in the next second."

It is basically certain that the sonic attack was sent by the No. [-] monster.

"As for the practicability of sonic weapons, I don't think it's necessary to get too nit-picky. That's a matter for the pioneers."

This sentence suddenly woke up Lao Pan.

He patted his head.

Those aliens even created wormholes, so why is it unacceptable to create a monster with a powerful sonic weapon?

The world is already sci-fi enough.

For now it is enough to determine that the monster may have this ability.

After figuring out the problem, Lao Pan ordered again:

"I am now issuing an order. The monster currently attacking Hong Kong is code-named [Horn]. It is speculated that it can launch a large-scale and high-intensity sonic attack. Neighboring PPDC member states are requested to send drones to reconnaissance..."

Zhang Tianyuan was also talking to Ning Jihua and Taylor: "Send more satellites to watch this monster. Since this monster has a sonic weapon, there is a high probability that it will always float on the sea."

The two immediately agreed, and soon passed the previously established emergency procedures to connect more satellite images to the base.

The clear image of the monster was quickly sent back to everyone.

It was a lizard-shaped monster, floating on the sea surface, from head to tail, its whole body was covered with vertical band-like structures, and it was still vibrating violently, and even the surrounding sea water seemed to be boiled , keep rolling...

Mori Mako gave a brief explanation: "According to the analysis of the image of the sea surface sent back now, the speaker is about 168 meters long and crawls on four legs. There are a large number of vibrating vocal cords on the back. When shaking, it will send out high-intensity sound waves to the surroundings. Almost Covers all frequencies."

"What is the killing range of the sound wave?" Zhang Tianyuan asked.

Mako Mori glanced at the data: "It has been detected now, and a noise of 130 decibels can still be detected five kilometers away."

130 decibels...

Everyone looked at each other.

Sudden exposure to this decibel volume is not uncommon for inner ear injuries and even hearing impairment that modern medicine cannot fully cure.

Lao Pan's face was serious: "This means that as long as the monster is five kilometers away from the coast, it can attack the residents of the city?"

"I'm afraid it won't stop."

Mori Mako shook her head and immediately added:

"The range of influence of the monster's sound waves is still expanding rapidly. According to speculation, the vibration of the vocal cords on the monster's back will become stronger and stronger over time."

Gee!

Zhang Tianyuan put his hands together, supported his chin and fell into deep thought.

Even he found the monster tricky.

Needless to say, this was another monster aimed at him.

Herald completely forgoes the combination of monsters that participated in the final battle in the original book.

It can be seen from this that they have realized that no matter how big a monster is, unless it can withstand the damage of falling from space, otherwise it will not be able to withstand a time-space exile.

That's why the Herald came up with these two monsters.

It can fly at one end and has perfect flexibility. If it falls from space, it can also glide along the trend.

One end can launch sonic attacks all the time, and he can't get close at all...

And the five-kilometer sonic attack range already exceeded the operating range of visually opening the space-time tunnel.

Even he had to admit that the pioneer really came prepared this time.

Not only Zhang Tianyuan, but Lao Pan and others were also worried about this monster.

They also saw that this monster was specially designed to cope with the time and space exile.

"Can our current mecha deal with sonic attacks?" Ning Jihua asked Lao Pan.

Before Lao Pan could answer, Mori Mako said: "Yes, the interior of the cockpit of all mechas is completely sealed, and it is difficult to transmit the energy of sonic weapons."

"Then let's send another mecha back to protect Hong Kong?"

As soon as Lao Pan put forward this idea, Cai Tiantong, who has been hanging on the communication channel, immediately reminded:

"Currently there are two monsters on the bottom of the sea. They are also level five monsters. In addition, it is difficult for mechas to fight under the sea. If we only keep two mechas..."

No need to go on.

Everyone knows what the consequences of that will be.

Even on land, a mecha might not necessarily be an opponent of a level [-] monster, let alone on the bottom of the sea where movement is difficult, which is the home of monsters.

Leaving only two mechas there is tantamount to letting them die, and the nuclear attack on the wormhole plan is impossible to complete.

But what will the Hong Kong government do if the mechs are not adjusted to come back to defend?

"Then let's turn the storm crimson back first?" Lao Pan tentatively made this suggestion, while paying attention to Taylor's face, seeing that he was already extremely dark.

However, Zhang Tianyuan shook his head.

"Turn Storm Crimson back to Hong Kong, what about San Francisco?"

"That monster can fly. Once it is not eliminated in time, it may fly somewhere next time. Maybe it will trigger a crisis of monster proliferation..."

This problem is the most serious.

Let a flying monster stay on the earth, what if it is a pregnant individual like the standing mouse before, and it is specially smuggled to the earth to give birth, what if you want your child to be an earth beast?

Isn't this equivalent to letting monsters take root on the earth?

Others also thought of this question, and their faces were gray for a while.

This is simply a trolley problem.

Either give up the Hong Kong government, or give up San Francisco, or give up the nuclear attack on the wormhole plan...

Just when everyone was having a headache, Zhang Tianyuan suddenly said:

"The Pangu should also be able to withstand sonic attacks, right?"

Mori Mako nodded instinctively: "Yes, its design technology is advanced, and its tonnage is heavier. Whether it is sound waves, electromagnetic lasers, its defense effect is the best among all mechas..."

After speaking, she realized Zhang Tianyuan's hidden meaning.

Others also looked over.

Chapter 213 Follow your orders!

"President, are you planning to drive the Pangu to fight against monsters?" When Lao Pan asked this sentence, he didn't know whether he would support this decision or not.

Ning Jihua frowned, "Isn't this too dangerous? The size of a level five monster is already about the same as that of the Pangu, so let's give up the plan to attack the wormhole with nuclear weapons."

Even Taylor nodded beside him, "We still need the guidance and help of the Mutual Rescue Society in this time and space, Mr. President, please don't be impulsive..."

Taylor's mouth moved, and he was about to suggest abandoning San Francisco. Compared with losing Mutual Aid, what is San Francisco?

But at this moment, Zhang Tianyuan waved his hand:

"I just use the mecha to get close to monsters, I don't use mechas to fight monsters."

He was crazy to drive the mecha to fight monsters.

Although he can pilot the Pangu solo, he hasn't received a lot of mecha training. If he really uses the mecha to fight monsters, his results may not be much better than those little kids in Huan Tai Er.

So he just planned to use the mecha to cover a layer of turtle shell, to gain the chance to accept the monster.

After he gets close to the monster, he can send it on a trip directly.

After hearing Zhang Tianyuan's explanation, Ning Jihua and Taylor still felt that the risk was too great.

Only Lao Pan hesitated for a moment.

Front-line personnel like him have seen countless tragedies caused by monsters, and hope that the disasters brought by monsters will come to an end.

This is arguably the closest they've come to ending the monster crisis.

He didn't want to give up halfway like this.

It's just that his idea obviously won't be supported...

When he was in a daze, Zhang Tianyuan suddenly patted him: "Old Pan and Makoto Mori, you should prepare for it. We will return to the Mo Yulan base later, and I will attack with the Pangu. You can provide me with the monster's march." path."

"We don't wait for the monster to reach the sea, we will attack as soon as we are ready."

This shot seemed to have an electric current passing through Lao Pan's body, which made him tremble, and then he came back to his senses and saluted Zhang Tianyuan with a straight military salute: "Follow your orders!"

Mako Mori also puffed out her chest, and also saluted.

After finishing speaking, the father and daughter left immediately to inform Mo Yulan's base to check the mecha and prepare for dispatch.

Ning Jihua saw that Zhang Tianyuan had made up his mind, he sighed and did not persuade him any more.

On the contrary, Taylor refused to give up.

He really would rather give up San Francisco than Zhang Tianyuan take the risk.

After all, Zhang Tianyuan is also his backer now, who would want his backer to take risks?
