Disguised as a man to be a schoolmaster

Chapter 201 Sonic Weapon?

The policeman has been tortured by this lighthouse and has gone crazy. Although it is the age of civilization with advanced technology, but if he sticks here, he is almost going crazy!
Thank goodness, finally, someone from above came down!
Zhuge Qingqing took out a notepad and asked while observing the surrounding information.

"What's the situation now?"

Police Xiao Wang: "We still dare not get close to the cordon. As long as we enter the cordon, we will hear a special buzzing sound. Before, we did not make any preparations. Several of my comrades were confused by this sound, like As if in a daze, they dropped the guns they were wearing and walked directly into the lighthouse in a daze! After entering the lighthouse, they only heard a scream, and then never came out again!"

Zhuge Qingqing: "How many of you are there?"

"We first received a report from a villager here, saying that he had lost a cow. We sent out the police with four people, but the four policemen never came out. Later, we arranged for [-] colleagues to come together. Seek. Now me and my companion are the only two left."

Zhuge Qingqing wrote in his notebook: "A total of 25 people, 4 people disappeared first, then 18 people disappeared, and the remaining 2 people."

She looked at the data on the notebook and hesitated for a moment.

This number is wrong, where did the other person go?
Only then did Zhuge Qingqing realize that there was another person who reported the crime she had forgotten, so she changed the number of missing persons to 19.

She raised her head and asked, "Where is the informant who asked you to find someone?"

The policeman was taken aback, "I don't know."

When he first called the police, he hadn't called the police yet.

Since then, he has never seen the person who made the report.

Another policeman, Xiao Qi, said, "My colleagues and I were patrolling the perimeter. When we found that something was wrong with other comrades-in-arms, we fired warning shots to no effect. We didn't dare to take risks when we didn't find a safe way to get in. Go in. We know that something must have happened to them inside, but we have to spread the news, otherwise we will only be wiped out."

"Okay, thank you for your cooperation!"

When Zhuge Qingqing asked, Ye Junyu took out the sound wave detector prepared in advance, and was searching for sounds of various frequencies.

"Squeeze --"

"Beep beep-"

"Card--"

Ye Junyu changed several frequencies in total, and finally received a voice that sounded very harsh.

"This is infrasound. The frequency is very low. Infrasound will interfere with the normal function of the nervous system and endanger human health. Infrasound of a certain intensity can cause dizziness, nausea, vomiting, loss of balance and even depression."

Zhuge Qingqing: "If this infrasound wave is controlled by someone, I think it is the culprit that caused your colleague to lose his mind!"

Chen Xi frowned. She had seen it on the news before. This kind of sonic weapon can kill people invisible. Someone put a sonic generator into the sea. dying soon.

If human beings are exposed to super-strong infrasound waves, it will cause deafness, coma, and even death!

Since infrasound waves have very long wavelengths, they are not easily attenuated in most media, so their propagation distance can reach very long.

If someone really brought this sonic weapon to the lighthouse, what was his purpose?
