Chapter 858: Solution

Chapter 858
East China Sea time, ten o'clock in the evening.
The street lights are still working.
Under the night sky, in the light, countless Donghai people walked out of their warm home.
They are wearing all kinds of pajamas.
Some even wear only a pair of underwear.
They walked along the street, their eyes dull, like marionettes, slowly...moving.
Unexplained sound from his mouth.
I can't feel the cold of winter at all.
They looked like walking dead, without the slightest anger in their eyes.
In the hall, Zhou Yang frowned.
"Zhou Yang, have you seen it." The person in charge said with a solemn expression.
"When did it start?" Zhou Yang asked.
"It's about an hour after the last patient entered treatment." The person in charge looked at his watch, "That is...two days ago."
Zhou Yang said in amazement, "Cheng Xiaoman has been pushing for two days?"
The person in charge nodded: "Yes, you just finished treating the last patient at that time, and then we plugged Cheng Xiaoman into the instrument, and then this happened outside."
"In the beginning, only the nearby residential areas were affected. Now, almost half of the East China Sea is being affected." The person in charge scratched his head with depression. "Preliminary estimates indicate that there are about 140,000 people entering this state of sleepwalking. ."
"Fortunately, no other accidents have occurred."
Zhou Yang's heart was shocked.
140,000 people... what kind of concept is this!
At this moment, Zhou Yang finally understood.
What did the man behind this incident, the "Cheng Xiaoman" in the consciousness layer mean?
Human beings who lose their consciousness and have only their physical instincts are not walking dead?
"Zhou Yang, what should I do now?" The person in charge was sweating profusely.
The communication channel with Beijing has been kept open.
The East China Sea is under great pressure.
"Everyone, now start to figure out how to interrupt this collective sleepwalking state." The chief executive said loudly.
Zhou Yang's face was so solemn that he walked to the corner of the hall.
"System, what to do?" Zhou Yang said in his heart.
"The host wants to understand why some people are affected, but some people are not?" The system prompts.
Zhou Yang frowned and thought for a moment: "Does anyone have antibodies?"
"Remind the host again, the dream is also a kind of wave." The system said.
"You mean...frequency?" Zhou Yang asked.
"Consciousness, like dreams, are both manifestations of waves. The wider the band covered by the Dream Eater, the more people it will influence."
"Similarly, if the host wants to complete the task and eliminate the Dream Eater, he must expand the band that he can influence."
"In addition, the sound wave coverage of the host needs to be large enough!"
Zhou Yang's eyes lit up instantly.
As long as there is a way, there is no need to worry about it.
Zhou Yang walked with wind and returned to the crowd.
"Papa!" Zhou Yang slapped twice.
The attention of everyone was attracted.
"I need your support!" Zhou Yang said loudly.
"Say, fully cooperate!" The person in charge of the scene said.
"I need a device that can collect ultrasonic waves! I also need a speaker that can broadcast ultrasonic waves. At the same time, I want everyone in the East China Sea to hear it!" Zhou Yang scanned the audience with firm eyes.
Everyone looked at each other.
"Zhou Yang, what are you going to do?" Professor Li asked.
Zhou Yang said solemnly: "All the Donghai citizens who sleepwalking are affected by some kind of ultrasound. Just wake them up."
"Didn't you mean that sleepwalkers can't wake up?" a researcher said loudly.
"I didn't say to wake up on the spot!" Zhou Yang said.
In a short period of time, Zhou Yang made a judgment.
Infrasound and ultrasound, which one does the Dream Eater emit?
From the appearance of the 140,000 sleepwalkers, their physical functions are fairly normal.
So Zhou Yang was extremely bold to speculate that the Dream Eater should use ultrasound.
Because Zhou Yang knew best about the harm of infrasound to the human body.
"I know where it is!" said an official. "In Donghai, there is a sound laboratory with a set of high-precision ultrasonic generators and a complete set of speakers."
"Can you pick up the sound?" Zhou Yang said.
"Of course it can, but the ultrasound produced by the instrument has a limited range..."
Zhou Yang waved and interrupted: "I will record it myself!"
"Huh?" The audience was surprised.
"You? Can emit ultrasound?" One researcher was dumbfounded.
Zhou Yang was too late to respond, but went on to ask: "How can the Donghai people hear the ultrasound I made?"
The person in charge of the hall said in a deep voice, "Zhou Yang, leave this to me, and you will record it now!"
"Good!" Zhou Yang nodded and walked out.
The person in charge immediately contacted the helicopter to stand by outside.
time is life.
...
"System, how can I control the bandwidth of ultrasound?"
On the helicopter, Zhou Yang asked in his heart.
"The host only needs to continuously emit ultrasound, and I will adjust the rest," the system said.
Zhou Yang's heart was instantly peaceful.
Due to the presence of official personnel, the license to use the sound laboratory was quickly obtained.
When the helicopter landed on the top of a certain building, there was already a group of people waiting.
Zhou Yang got out of the cabin and everyone immediately surrounded him.
"Mr. Zhou Yang, please come with me!" A gentle and elegant middle-aged man smiled and made a please gesture, "Your request, my laboratory will fully cooperate!"
"Thank you!" Zhou Yang nodded in greeting.
"Don't say that, to help Mr. Zhou is to help the citizens of Donghai!" The middle-aged man was obviously excited.
A group of people took the special elevator and quickly entered the fully silent laboratory on the 23rd floor of the building.
This laboratory is big enough and high-end enough.
It occupies a whole floor.
"Our laboratory provides a variety of sound sources for major companies around the world. They are all ultra-high-precision, and some sound diffraction experiments are also held here!" The middle-aged man led Zhou Yang into the laboratory. After passing through the disinfection channel, the white protective clothing was changed.
"Mr. Zhou Yang, I take the liberty to ask, what is the approximate frequency of the ultrasound you need this time, so I can let the staff adjust the machine in advance and prepare for recording." The middle-aged humane.
"What is the limit?" Zhou Yang said.
"The highest medical standard can be reached, 30 MHz."
"I'll do it myself...your limit is not enough!" Zhou Yang waved his hand.
"It's impossible!" A staff member spread his hands, "30 MHz is not enough? Besides, Mr. Zhou, how do you record it? Are you going to send out the ultrasound yourself?"
The boss of the laboratory glared at the employee.
Zhou Yang is extraordinary.
The official endorsed him.
Don't cause trouble.
The staff had to sigh.
However, it seemed that he was still not satisfied.
"There is no time, let's just record it!" Zhou Yang said, "As for whether I can send out UHF, you will know soon!"
